FERC Investigation Faults ISO-NE in Capacity Market Fraud

ISO-NE violated its tariff in its handling of construction delays at a Boston-area generating plant, FERC said, slapping the RTO with a $500,000 fine.

In an order issued on Friday, FERC agreed to a settlement requiring the grid operator to boost its compliance program for making capacity payments to the New Salem Harbor Generating Station before it had started operating or even finished construction (IN18-8).

The FERC filing builds on its settlement with the project’s developer, which was recently handed a $17 million fine for misleading ISO-NE about the project’s timeline. (See Developer in ISO-NE Hit with FERC Fine for Capacity Market Fraud.)

ISO-NE has repeatedly denied wrongdoing and called itself the victim of fraud. But FERC made clear in its order that they believe the grid operator played a role in encouraging the Salem Harbor developers to present misleading information about when the project was expected to be finished.

The gas-fired combined cycle generation plant had a planned commercial operation date (COD) of May 31, 2016, when it cleared the RTO’s Forward Capacity Auction In 2013. It was awarded a capacity supply obligation of 674 MW for the delivery year beginning June 1, 2016. FERC noted that the plant, which went into operation in June 2018, was the first new merchant generating resource to clear in ISO-NE’s FCA.

ISO-NE’s Violations

The FERC settlement lays out a detailed paper trail showing that ISO-NE failed to meet its duties under its tariff as the project was in development.

As likely delays popped up, Salem Harbor Power Development repeatedly provided information to ISO-NE about changing milestone dates, which should have led the company and grid operator to put forward a new commercial operation date, FERC found.

Instead, ISO-NE staff encouraged the developer to maintain May 31, 2017, as the COD. ISO-NE’s former director of resource adequacy did so explicitly to avoid triggering the automatic submission of a demand bid in the reconfiguration auction (ARA3) and forcing the company to give away its full capacity supply obligation, FERC said.

ISO-NE also violated its tariff by failing to submit a demand bid and submitting an inaccurate qualified capacity value, FERC’s Office of Enforcement found.

ISO-NE employees had enough information to know that they should have qualified it for 0 MW, FERC said.

Instead, the facility was qualified at 674 MW, which helped it earn more than $100 million in fraudulent capacity payments.

And finally, FERC found that ISO-NE restricted the access of its own Internal Market Monitor to capacity market data, including the narratives filed by the project’s developer, as the situation was unfolding.

“Enforcement concluded that System Planning’s conduct not only violated the tariff, but also frustrated the IMM’s key market oversight role,” the order reads.

ISO-NE spokesperson Matt Kakley said that since the incident, the organization has “taken steps to ensure that no one staff person can take such an action.”

And he noted that the Monitor was still able to obtain the information needed even while access to the data was curtailed.

An Intentionally Light Fine

ISO-NE did not admit or deny the violations put forward by FERC, but it agreed to a $500,000 civil penalty and $350,000 worth of compliance improvements.

Those include expanding a portal for employees to anonymously report potential violations, a new training module on tariff compliance and the role of the Monitor, and compliance monitoring by FERC.

“We recognize that a larger civil penalty might otherwise be appropriate given the magnitude of the capacity payments that ISO-NE made to Footprint,” FERC wrote in its order. “However, such a penalty likely would be passed on to the fee-paying entities, potentially compounding the harm to those entities and undermining the deterrent value of a larger civil penalty.”

ISO-NE acknowledged the possible harm to ratepayers too, by saying that its executives will pay the fine.

“ISO New England’s senior management takes responsibility for the ISO’s role in this matter. Therefore, the financial penalty outlined in the settlement agreement will be paid through a reduction in executive compensation,” the grid operator said in a statement.

Kakley said that will come in the form of a pro rata reduction, and that it will be made public in the form of the RTO’s financial reporting.

ISO-NE Response

The grid operator maintained a defiant tone in its statement on the settlement, saying that the events were precipitated by “Salem Harbor Power Development’s failure to provide accurate and complete information to ISO staff.”

But ISO-NE also recognizes that the investigation “revealed inadequacies in the market rules and our internal controls, and areas where better judgments could have been made.”

It has since changed capacity market rules to include an automatic financial penalty for resources that are behind in their development, and worked to “foster increased information exchange among internal groups.”

The issue of project delays wreaking havoc on the capacity market has not gone away. The results of this year’s capacity auction were significantly delayed while ISO-NE waited for FERC and the D.C. Circuit Court of Appeals to settle litigation over Killingly Energy Center, which had its capacity supply obligation pulled by the grid operator because of its failure to meet milestones and stay on track for its COD.

NJ County Asks BPU to Slow Approvals for First OSW Project

The New Jersey county of Cape May asked the state Board of Public Utilities (BPU) on Thursday to slow the approval process for an easement to run power cables from the state’s first offshore wind project — Ocean Wind 1 — across county land until federal environmental studies are completed.

Michael J. Donahue, representing Cape May County | New Jersey Board of Public Utilities

Michael J. Donahue, a lawyer and former state superior court judge representing the county at two online BPU hearings, said the federal environmental impact study could provide information that is relevant to whether the cable route is feasible or not.

Donahue, who said he also represents 10 of the 16 communities in Cape May County, also urged the BPU to consider alternative routes more acceptable to area residents, many of whom oppose the project.

Danish developer Ørsted is seeking BPU approval for an easement to run cables bringing energy from its Ocean Wind project to a substation that would tie the project to the grid. The developer’s favored route runs through the Jersey shore community of Ocean City, which is in Cape May County.

The case is related to but separate from Ørsted’s petition for an easement running across public land in Ocean City, which the BPU approved on Wednesday. (See NJ BPU Approves Easement Plan for 1^st OSW Project.)

Ørsted’s second petition also seeks BPU consent for the developer to obtain several environmental and other permits needed to get project approval from the New Jersey Department of Environmental Protection (DEP).

The case is the second test of a controversial law (S3926) enacted in July 2021 that allows offshore wind developers to site power cables and equipment on public land regardless of local or state government opposition. If the BPU backs the easement and consents, the developer would not need approval from the county or Ocean City, which also opposes the project.

“The county is not trying to delay or obstruct,” Donahue told the hearing. “But we think it’s important that many of the issues that concern the people of Cape May County be given an opportunity to be heard.”

Donahue said the county had had “discussions over a long period of time” with Ørsted about the project, including an attempt to “modify the impacts, especially in terms of cluttering the horizon.” But the two sides failed to reach an agreement, he said.

“We urge the board, as Ocean City has, to wait for those federal environmental processes to be completed so we don’t have the prospect of having to do all this all over again,” Donahue said. The proposed route could jeopardize sensitive marshes and impact area historical sites, he argued, and it could “conflict with many utilities that already exist” in the area, including sewer, gas and water main lines.

Negative Impact

The 1,100-MW Ocean Wind project, which the BPU approved in 2019, was the first of three offshore wind farms approved by the state to date. The BPU expects to follow the approval of the 1,148-MW Ocean Wind 2 and the 1,510-MW Atlantic Shores in 2021 with a third solicitation for 1,200 MW in the first quarter of 2023. (See NJ Seeks Stakeholder Input for 3rd OSW Solicitation.)

The projects are part of Gov. Phil Murphy’s goal, signed on Sept. 21, that the state have in place 11 GW of offshore wind capacity by 2040. That goal replaced Murphy’s earlier goal of 7.5 GW by 2035.

The Bureau of Ocean Energy Management issued a draft environmental impact statement (EIS) on Ocean Wind 1 on June 22, with comments due by Aug. 23. The draft found that the project would not have major impacts on most of the 19 environmental and related categories scrutinized.

But the 1,408-page report did find that the construction and installation, operations and maintenance, and eventual decommissioning of the project would have major impacts on marine navigation and vessel traffic, as well as commercial and recreational fishing. (See BOEM Draft EIS Finds Potential Major Impacts from 1st NJ OSW Project.)

BOEM held three public hearings on the draft in July. The agency said that after it “addresses the comments provided,” it will issue a final EIS that will “inform” its decision to “approve, approve with modifications or disapprove the project.”

But federal approval is only one hurdle for Ocean Wind 1. Ørsted is seeking a 30-foot-wide easement running about eight miles along the length of Ocean City, a popular tourism and vacation area on the Jersey shore. The 275-kV line will connect the project’s turbines, about 15 miles offshore, to the PJM grid at a substation sited on a now closed coal-fired power plant in neighboring Upper Township.

At issue in the Cape May case is the project’s need for a temporary 18-month easement and a 30-foot-wide permanent easement across county land, both in Ocean City, the developer’s May 20 petition says.

The BPU’s approval of the Ocean City easement on Wednesday was a big step forward for Ocean Wind 1, allowing project cables to pass across land in Ocean City created with funds from the state Green Acres program, which pays to improve parkland and open space.

The case, which involves the same cable route as the Cape May County case, was the first test of the law granting the BPU power to override local officials on issues involving offshore wind projects. The law allows the BPU to do so — and grant approvals on projects — if the agency concludes that they are “reasonably necessary” to the project.

Madeline Urbish, Ørsted’s head of government affairs | New Jersey Board of Public Utilities

As in the earlier case, Ørsted argued that they are. Madeline Urbish, the company’s head of government affairs, told the hearing that the project needed the BPU’s approval to move ahead and meet New Jersey’s clean energy goals, after the developer had held fruitless discussions with Cape May County since 2019.

“Time is of the essence if the project is going to meet its commitment to New Jersey” and reach commercial operation in 2024, Urbish said.

“Cape May County has not been willing to reach the necessary agreements to allow the project to proceed,” she said. The county’s approval and permit consents are required for the project to secure approval from the DEP, whose blessing is needed in turn for the environmental review conducted by the federal Bureau of Ocean Energy Management.

Alternative Route

Donahue countered that in order to limit disruption and negative impacts from the transmission lines, the BPU should consider cable routes for two other offshore wind projects approved by the agency — Ocean Wind 2 and Atlantic Shores — at the same time as the route and easements for Ocean Wind 1.

Instead of running the cables through Ocean City, Ørsted could send them along an abandoned railroad or part of the Garden State Parkway, the main highway along the Jersey shore, he said.

More than a dozen speakers at the two hearings on Thursday opposed either the granting of the easement or the project in general. Many said they are Ocean City residents, and some were clearly upset by the BPU’s intervention in what they considered a decision that should be taken by local officials.

Ocean City’s business administrator, George Savastano | New Jersey Board of Public Utilities

George Savastano, Ocean City’s business administrator, questioned the legitimacy of the law and the “authority” of the BPU to make decisions on the easement issue. “It remains to be seen whether it will survive judicial scrutiny,” he said of the law, citing a section of the state constitution that, he said, states “any law concerning municipal corporations formed for local government or concerning county shall be liberally construed in their favor.”

Savastano also argued that Ørsted’s designation of several alternative routes for the cable means that the chosen route through Ocean City is not “reasonably necessary.” That question is enough reason for the issue to be heard by an administrative law court, rather than the BPU, he said, and urged the agency to send the case to the court.

At a hearing on the first easement case in June, Ocean City called on Ørsted to choose a route that would avoid the municipality and instead send the cable through Great Egg Harbor Bay, coming on shore close to the substation in Upper Township and avoiding Ocean City altogether. Cape May County also supports that route.

Savastano said that the route through Ocean City is shorter, and so likely cheaper for the developer, who should, as a result, be required to divulge the cost of pursuing each of the available routes.

“Until and unless Ocean Wind discloses the cost of each of the alternate routes, the board cannot find that the easements and consents which Ocean Wind claims to need are reasonably necessary,” he said.

The BPU has said in the past that the cost of any of the routes is irrelevant to the discussion because it will be paid for by Ørsted and won’t be an expenditure of public money.

Con Edison to Sell Clean Energy Businesses for $6.8B

RWE Renewables Americas will acquire Con Edison Clean Energy Businesses in a deal valued at $6.8 billion.

Their parent companies, Consolidated Edison and RWE AG, announced the agreement Saturday. It is expected to close in the first half of 2023.

Con Ed CEO Timothy P. Cawley said in a news release that the move will allow the utility to concentrate on its core operations.

“The transaction we announced today will allow Con Edison to sharply focus on our core utility businesses and the investments needed to lead New York’s ambitious clean energy transition.”

Con Ed also said it will continue to invest in clean energy transmission projects, building electrification, energy efficiency, electric vehicle infrastructure, battery storage and other technologies.

Con Edison Clean Energy Businesses operates more than 4 GW of renewable energy projects in North America through its three primary subsidiaries, Con Edison Development, Con Edison Energy and Con Edison Solutions.

RWE, based in Germany, said the Con Ed acquisition will nearly double its capacity in the U.S., give it a broader geographic footprint and expand its project pipeline to include more than 24 GW of onshore wind, solar and battery storage.

RWE is also expanding its offshore wind development efforts to the U.S. Earlier this year, it and partner National Grid submitted a successful $1.1 billion bid to secure OCS-A 0539, the largest offshore wind lease in the New York Bight. It is also a partner in an 11-MW demonstration project planned to test floating turbines in the Gulf of Maine.

RWE’s CEO and CFO have scheduled an investor and analyst conference call Oct. 4. The company said in a news release that the acquisition is a milestone in its growth plans in the U.S., a large and fast-growing market for renewables that recently got a 10-year stabilizing boost in the form of the Inflation Reduction Act.

“The unique combination of complementary portfolios in onshore wind, solar and batteries creates one of the leading renewable companies in the U.S. market,” RWE CEO Markus Krebber said in a news release. “The combined development pipeline, one of the largest in the U.S., provides tremendous opportunities for sustainability and value accretive growth, backed by a strong financial position.”

RWE Renewables Americas has developed more than 3.8 GW of renewable capacity in North America since 2007.

Con Ed said the transaction is subject to customary closing conditions, including expiration or early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and approvals by the U.S. Committee on Foreign Investment and FERC.

USEA Panel Explores How to Cut CO2 as Electricity Demand Increases

The impact of growing power demand driven by the electrification of transportation and buildings is a key problem in the drive to decarbonize U.S. electricity that utilities and regulators must tackle, said Robert Rowe, president of NorthWestern Energy.

Robert Rowe, NorthWestern Energy | USEA

Speaking at an online panel on Friday sponsored by the United States Energy Association, Rowe said U.S. utilities have already made significant cuts in their carbon emissions, but new approaches are needed for regulation and, in particular, rate structures.

The industry needs to spell out its “absolute core goals — safety, reliability, resilience, flexibility, decarbonization … as simply as possible, measurably, and then look at the regulatory mechanisms in place and ask, ‘Do they advance these goals, or do they hold you back?’” he said.

According to the Clean Energy States Alliance, 21 states, plus D.C. and Puerto Rico, have adopted 100% clean energy goals, with deadlines ranging from 2032 to 2050. Many investor-owned utilities, including NorthWestern, have followed suit, committing to clean or net-zero generation, usually by 2050.

Jim Matheson, NRECA | USEA

NorthWestern is “working with others on the electric infrastructure to support [electrification], whether its fleet electrification, personal vehicles, processes,” Rowe said. “There’s a lot of good in there, but the key is cost-effective electrification.”

Jim Matheson, CEO of the National Rural Electric Cooperative Association, argued that President Biden’s 2035 clean electricity goal may not be achievable “without severely compromising the reliability of the electric grid.”

“We think you have to have some form of always-available power,” Matheson said. “It could be nuclear; it could be coal; it could be natural gas. But in a situation where we need more electricity, the question is — how much of the portfolio can be an intermittent resource?”

More time, more advanced technologies and way more transmission will be needed, he said.

Bridge to Bankability

Jigar Shah, director of the Department of Energy’s Loan Programs Office (LPO), sees the challenge in terms of technology “liftoff”: the billions in upfront investment needed to bring new technologies to market.

Jigar Shah, DOE Loan Programs Office | USEA

The LPO’s $465 million loan to Tesla in 2010 — and the company’s payback of the money ahead of schedule — was critical in the electric vehicle manufacturer’s buildout of its Gigafactories and the growth of the now booming EV market in the U.S.

But, Shah said, a range of industry analyses show “there are 20-plus sectors that have to cross the bridge to bankability and reach full market acceptance for us to have a chance of meeting the 2035 goals the president has set down, and right now, those 20 sectors have not crossed.”

It takes about $100 billion in investments to achieve bankability, Shah said. While he sees momentum and growing interest in hydrogen, “in sector after sector, there is an assumption that the commercial markets are ready to go, but I think, in general, they’re really only interested in solar, wind and some battery storage.”

Rowe added that beyond technology risk, developing the ecosystem of supply chains, workforce and permitting will layer on more uncertainties. “Getting all those pieces together, like every transition, it’s messy; it’s complicated; it takes longer than you might have thought at the start,” he said. “But when you look back, you may have accomplished more than you actually did.”

David Naylor, Rayburn Electric Cooperative | USEA

Having a diverse generation portfolio and finding ways to leverage existing transmission and distribution systems were seen by other speakers as familiar, low-risk strategies to move decarbonization forward in the near term.

David Naylor, president and CEO of Rayburn Electric Cooperative, a transmission and generation cooperative in northeast Texas, said his co-op is going “low-tech” by upgrading its conductors “to utilize existing rights of way but get more throughput.”

At the same time, the co-op plans to increase its use of renewable power, from 5% in 2020 to 31% by 2025, according to its website. Other electric cooperatives, which often don’t have to obtain the regulatory approvals required of IOUs, have adopted more ambitious clean energy goals.

New Mexico’s Kit Carson Electric Cooperative this year hit its goal of providing 100% of its daytime power from solar, while keeping rates low.

Grid Management 2.0

Energy efficiency and demand response will become integral tools in grid management and modernization, but Rowe sees a potential obstacle in designing electric rates that encourage grid efficiency.

“Does it make sense to pay for that [efficient] infrastructure volumetrically?” he said. “It’s a little bit like you’ve got one foot on the brake — efficiency — and one foot on the accelerator — volumetric pricing — and you need a one-pedal operation. Where do you try to harmonize?”

Demand management will also be critical for integrating power to meet the increasing demand from EVs, said Matthew Lind, director for industry consultants 1898 & Co., a part of Burns & McDonnell.

He pointed to efforts by Edison Electric Institute to “bring together the electric retail provider and technology companies to develop different kinds of strategies. Demand response and time of use are necessary, but not sufficient. … The size of the resource, the ability to access that resource is going to vary pretty tremendously from area to area, depending on the nature of the demand.

Matthew Lind, 1898 & Co. | USEA

“The ability to curtail that demand on the electric side may be challenging as we further electrify other sectors of the economy,” Lind continued. “But diversity of technologies — demand response being one of those technologies — will allow for reliability and, hopefully, affordability as we make this transition.”

Rowe also cautioned that demand growth encompasses more than capacity. “Even using relatively conservative assumptions about growth, there are some significant capacity challenges on our system, and if growth exceeds that, then we have to redouble our efforts,” he said. “Capacity is not simply a supply concept. It’s how much reserve, how much [flexibility] do you need in all aspects of your system, and what’s the cost and what’s the value of that?”

Shah foresees transportation electrification driving a more radical transformation. Citing figures from Wood Mackenzie, he predicted that by 2030, the U.S. would have about 100 GWh of utility-scale storage on the grid. He also estimated that batteries in passenger and other light-duty EVs could provide as much as 800 to 850 GWh of storage.

“To suggest that this is something other than a mainstream grid operations exercise is ridiculous,” he said. “This will literally become the next way you manage the grid; even if you decide not to pull any power out of the [EV] batteries, that’s V2G [vehicle to grid]; even if you just do managed charging.

“I just think that people are using the model of last year to predict the model of 2030, and they’re just getting it woefully wrong,” he said.

‘Do Big Things’

The energy transition in the U.S. has hit a push-pull stage.

The Infrastructure Investment and Jobs Act and the Inflation Reduction Act provide strong support for clean energy buildout, such as the IRA’s direct-pay provisions that for the first time allow co-ops and municipal utilities to access a range of clean energy tax credits.

But 20 states now have laws prohibiting local jurisdictions from banning natural gas hookups in new construction, and six more are considering similar laws, according to S&P Global.

Rowe said conservative states, like the three in NorthWestern’s service territory, prioritize reliability and affordability and make investments in decarbonization based on those priorities.

“I am very uninterested, deeply uninterested in the kind of polarizing discussions where everybody takes their ideological position,” he said. “On the other hand, everyone is truly concerned about the various severe weather events, truly concerned about resilience. … I wish we could find a broad space where we can agree, and then focus on the most efficient ways to get there.”

Shah sees electrification as an unstoppable process. Banning bans on natural gas hookups may slow but won’t stop the shift to air- and ground-source heat pumps, he said, noting that they are now being installed in 38% of new homes, according to the National Association of Home Builders.

“You don’t replace natural gas in these applications through sacrifice; you replace it through better technology, and people generally like heat pumps a lot better than using natural gas for heating,” he said. “Now we’ve got to train HVAC contractors; we have to train the supply chain. We have to do all the hard work to make sure the transition occurs, and consumer preferences are honored.”

The speed of the energy transition and demand growth, and the need for the industry to stay in front of both will be a core challenge moving forward, he said.

“People have been used to being able to just use their existing infrastructure for longer without really thinking about how to add more infrastructure, but America’s got to be able to do big things again,” Shah said. “We have the right people; we have clearly all the technology, and the question becomes how do we really do big things again? We know how to do this; it’s a human issue around how we move faster, how we move more confidently and then how we export those solutions to the rest of the world.”

Lordstown Motors Begins Production of Electric Pickup Truck

Lordstown Motors (NASDAQ:RIDE) announced late last week that the first two of 50 electric pickup trucks it plans to produce and sell this year had rolled off the assembly line at the former General Motors production plant in northeast Ohio.

But the future of the Endurance model and the company is still in question.

The sprawling factory is now owned by Taiwanese manufacturer Foxconn, which agreed to assemble the Endurance when it bought the 6.2 million-square-foot plant in 2021 for $230 million.

Foxconn is also planning next year to begin manufacturing a small electric car, the PEAR, designed by Fisker. The company has also announced plans to produce an electric tractor in the facility for a small California startup.

Lordstown said in a statement that the 50 trucks it expects to deliver to customers this year are “part of the first batch of up to 500 saleable vehicles we intend to build.”

“We will continue to build at a slow rate as we address remaining part pedigree and part availability issues. We expect to increase the speed of production into November and December,” CEO Edward Hightower said. The Endurance has been crash tested, but the results must still be certified.

The company also noted in a simultaneous filing with the U.S. Securities and Exchange Commission that its production and delivery schedule is dependent upon raising additional capital.

“We expect to deliver approximately 50 units to customers in 2022 and the remainder of the first batch in the first half of 2023, subject to raising sufficient capital,” it said.

The company expects to end the third quarter with “cash and cash equivalents of approximately $195 million” and would continue to explore “capital-raising alternatives,” including partnership discussions with Foxconn, according to the filing.

FERC Commissioners Opine on Western RTO

TEMPE, Ariz. — FERC Commissioners Mark Christie and James Danly spoke last week about the West’s pursuit of greater regional coordination, with Christie praising the region’s “organic” efforts to form one or more organized markets and Danly warning against RTOs that fail to promote competition and reliability.

The commissioners made their comments at the fall joint meeting of the Committee on Regional Electric Power Cooperation and the Western Interconnection Regional Advisory Body, where CAISO, SPP and the Western Power Pool (WPP) pitched their planned market and reliability programs.

CAISO is planning an extended day-ahead market (EDAM) for its real-time Western Energy Imbalance Market (WEIM). SPP launched its Western Energy Imbalance Service (WEIS) and is developing Markets+, a bundle of services that stops short of a full RTO. And WPP’s Western Resource Adequacy Program (WRAP) has attracted participants from across the Western Interconnection. It expects to begin a preliminary phase of operations soon as it awaits FERC approval.

“You’ve got a lot of options in the West now that are percolating up, and what characterizes every one of these options — the WEIM, the WEIS, the Markets+, the EDAM and [the WRAP] — is that these are all organic, that are coming from you,” Christie said. “FERC didn’t tell you, ‘Here it is. Do it.’ They’re being developed by you … to meet your needs, and I think that’s what’s so exciting. I’m a big believer in organic, evolutionary change [that is] bottom-up … and not being forced down from FERC.”

Christie recommended Western stakeholders look at “another organic development,” the Southeast Energy Exchange Market (SEEM), an automated bilateral 15-minute market set to launch later this year.

What’s important to recognize, he said, is that the West does not have to choose between no cooperation and an RTO.

“That’s not the binary choice that you face,” Christie said. “There are a lot of points on the continuum, and it’s for you to pick and choose what points makes sense for you.”

Christie, a longtime utility regulator in Virginia before he joined FERC, urged Western regulators to protect the public’s interests when considering their utilities’ plans to join organized markets.

Oregon PUC Commissioner Letha Tawney, who shared the stage with Christie and moderated the discussion, asked how state regulators could balance their roles of making neutral decisions on regulatory matters before them and advocating for the public’s interests when dealing with organizations such as CAISO, SPP and WPP.

Christie, a founding member of the Organization of PJM States Inc. (OPSI), said a “critically important topic” would be whether to form similar advocacy committees of state representatives in the West.

“It is unrealistic to think that states are not going to be cooperating and working with your fellow state regulators,” he said. “I mean, whatever you choose in the West — whether it’s just an energy market, an energy market plus a day-ahead market, [or a] full RTO with all the bells and whistles — whatever you choose you really need an organization like OPSI” empowered to have an advocacy role.

Governance and cost-allocation are among the issues sure to be argued over, he said.

“Cost allocation in a multi-state RTO with radically different [state] policies is an extremely difficult nut to crack,” Christie said. “And you all are sitting out here in the West … [where] every state not named California has a concern about who gets to appoint the board.”

Danly Speaks

In a separate session, Danly warned that joining an RTO could have significant drawbacks, especially if the RTO cannot ensure it has adequate resources or fair competition.

“I often think that people are not quite perfectly aware of the costs and benefits that market participation has,” Danly said.

“There are undeniable benefits that the markets have delivered,” he said. “They have driven costs for power down. There are efficiencies of scale that are so attractive that even those regions that do not want markets have, as in the case of SEEM, tried to capture as many of those benefits as they can. And that may well be the model that’s used going forward, that people creep right up to the line of a full-on RTO but don’t quite cross that threshold.”

Even so, the costs of joining a market can be “multiple,” Danly said.

“My admonition to any state or utility that’s contemplating joining markets in the West … [is that] you to do it with your eyes fully open,” he said.

A frequent CAISO critic, Danly pointed out the ISO’s problems as recently as last month in maintaining resource adequacy during summer heat waves. On Sept. 6 the utility declared a stage 3 energy emergency, instructing utilities to arm for load shed. It narrowly averted rolling blackouts after the California Governor’s Office of Emergency Services sent out a text alert to millions of cell phones telling residents to “conserve energy now” or “power interruptions may occur.”

The message reduced demand by 2,100 MW in 5 minutes, the U.S. Energy Information Administration said Wednesday.

CAISO has declared energy emergencies the past two summers and initiated rolling blackouts in August 2020.

“One of the biggest [drawbacks of organized markets] is what I think are the fairly evident failures of some of the markets to ensure resource adequacy,” Danly said. “And this is something that in the West you’re well aware of because of very recent experience in having had a squeaker with the hot weather in California [and] merely having made it through that with the lights on.”

Markets that incentivize and subsidize certain types of resources, lowering costs, impede the competition that makes a market work, he said.

“If you have a market structure that does not insulate itself correctly [from anti-competitive forces], then what you’re going to find, as we see for example in New England, is that the jurisdictions in which the market operates are acting to undermine the very premise of the market,” he said.

New England, long troubled by tight natural gas supplies in winter, is facing a more limited supply this year because of the war in Ukraine and the century-old Jones Act, which prevents foreign-owned tankers from bringing U.S. liquefied natural gas to domestic ports and forces New England to rely on Russian LNG.

“Markets, especially in the case of capacity markets, are there to ensure that a sufficient quantity of capacity is delivered,” Danly said. “That’s done by a series of auctions in which market incentives are supposed to draw people into delivering the quantity and type of resources necessary to ensure that the system remains stable and has enough electricity.

“And yet, when you have state policies enacted that serve to suppress capacity prices, then you find yourself short,” he said. “And right now, we have a market in the Northeast in which the market has told us in public, on the record, in a FERC tech conference that given the constraints under which it operates … it is not possible to use market mechanisms to ensure resource adequacy. That should be a chilling prospect for anybody who is considering participation in a market.”

If reliability is a problem in New England, where states “have similar and in-parallel public policy goals … I would just suggest that people imagine what it would be like to join a full FERC-jurisdictional RTO [in the West where] you would have a market that has to be the ultimate deliverer of services and guarantor of resource adequacy for states as divergent in their public policy goals as, let’s say, Oregon and Utah.”

Vegas Plans to ‘Engage Heavily’ in ERCOT Changes

Pablo Vegas, who took over as ERCOT’s CEO on Monday, remembers well his previous time in Texas over a decade ago.

“There were some changes going on at the time,” Vegas told RTO Insider last week from his previous office in Dublin, Ohio, referring to a “big push” for building out advanced metering infrastructure. As COO of American Electric Power’s AEP Texas subsidiary, it was Vegas’ job to ensure advanced meters were successfully installed.

Of course, things have changed since then. ERCOT transitioned from a zonal market to a more granular nodal construct — Vegas was involved in that too — and a 2011 ice event just before Super Bowl XLV in Dallas that led to rare rolling blackouts across the Texas grid. Two years later, a $6.9 billion transmission build was completed, opening the door to the 47 GW of installed renewable capacity now on the ERCOT system.

Then came February 2021 and an icy storm that knocked out almost half of the system’s winter capacity, primarily thermal generation still unprotected from extreme cold weather after 2011, and brought it to within minutes of a total collapse. Those disastrous events have led to greater regulatory and legislative oversight for ERCOT and a lack of trust among many Texans of its ability to keep the lights on.

A recent survey by Data for Progress found power and grid issues, along with immigration, were considered more important for lawmakers to address than even gun violence and general economic issues. “Higher home energy bills are detracting from Texas voters’ quality of life,” the survey firm said, pointing to the financial effects of ERCOT’s conservative operations posture this summer.

So why take this job? Vegas was asked.

A couple of big reasons, he responded.

“One, working for an organization with a really significant purpose is very compelling. ERCOT operates a market that serves 26 million Texans, and it’s a market that is experiencing some of the most dynamic change in the energy industry, anywhere in the world,” he said. “The opportunity to come in and to provide leadership and influence in that kind of environment, with an organization with that kind of purpose, is extremely compelling.

“Then add that it’s in Texas, where our family had a great experience and truly enjoyed our time when we were there,” Vegas said. “It’s at a point in time where I think the opportunity to influence some of the changes that are going to be going on in the market is right in front of us. As a leader, you’re always looking for those opportunities to drive positive change and to create positive change in the work that you and your teams can do. It was really a very unique and special opportunity that was presented and that I was excited to talk to the board about.”

Vegas said he plans to “engage heavily” in the changes being made to the ERCOT market. The Texas Public Utility Commission is currently overseeing what could be significant revisions to the energy-only market by adding dispatchable generation requirements, a “capacity-light” construct once considered verboten in the state. Lawmakers recently asked to review the new Phase II market design before it’s handed off to ERCOT for implementation. (See Texas Lawmakers to Vet ERCOT Market Redesign.)

“I’m looking forward to seeing the results of the work that the team has been doing as well,” he said, adding that he will work with market participants to ensure that the design’s concept and framework “aligns with the overall goals” of legislation passed last year in the winter storm’s wake.

“I plan to dive in and work with all the market participants to help to define the pathway for implementing those Phase II redesigns and to do so in a way as quickly as we can do it reliably and safely,” Vegas said. “Phase II is looking at the longer-term changes that are needed to ensure that the electric market is going to grow reliably along with the economy and … building deeper agility to respond to significant weather events and stresses on the system like it’s been experiencing over the last couple of years. It’s critical. It’s going to be one of the more significant evolutions in the ERCOT market since the transition from zonal to a nodal market.”

Market participants have provided their input last year on the redesign to the PUC but have largely been sidelined since then. A consulting firm, the same one that proposed the load-side reliability obligation mechanism thought to be the construct’s central part, is reviewing the commission’s market proposal. Stakeholders expect the PUC’s final design to be released in November for additional public input.

Transition Phase

Given the increased political and regulatory direction ERCOT now receives, Vegas knows stakeholder management will be a big part of his job going forward.

“It’s making sure that you know how to collaborate with diverse groups that have diverse interests and priorities. That’s something that I’ve worked through my career,” Vegas said. “Having a deep understanding of the political landscape is important. … My history and my work experience have given me a lot of experience and exposure around stakeholder management. Understanding the importance of collaborating with political people is really all a part of the package.”

The ERCOT Board of Directors announced Vegas’ appointment in August, ending a search that dragged on for months. He replaces interim CEO Brad Jones, who replaced Bill Magness when the latter was fired last year after the winter storm. (See ERCOT Names NiSource’s Vegas as New CEO.)

Vegas, 49, comes to the position having spent the previous six years with NiSource, the last two as COO of NiSource Utilities. He was with AEP for 11 years before that, including his stint as AEP Texas’ COO. His compensation will exceed $3 million, significantly more than the $800,000 Magness earned before he was among the ERCOT board members and PUC commissioners cut loose after the storm.

Born in Peru, Vegas grew up in Indiana. He earned a mechanical engineering degree from the University of Michigan and attended the Harvard Business School’s Advanced Management Program. He and his wife and three children plan to move to Texas.

A background steeped in consulting, management, strategy, IT planning and utility operations would seem to have Vegas well prepared for his new role. He and Jones, who provided a candid public face in the interim, will work together for a transition period that ends after October.

“Brad has been incredibly helpful. I’m grateful to have had the opportunity to transition with him because he is such a knowledgeable and deeply passionate for the work of ERCOT,” Vegas said, noting he has been meeting with Jones every week. “He’s been helping me understand the ERCOT organization; its people; the leadership team. … He has helped me understand how the organization has been implementing the [legislative changes] and the recent operational changes.”

Vegas said Jones has caught him up on the market changes since he was last in Texas. He has also spent time with ERCOT’s leadership team in gaining an understanding of the commercial operations, market operations and back-office support functions.

“My takeaways are that, one, we’re ready. We’re ready for this upcoming season and the winter that’s coming. The changes that have been put in place have been validated and verified. We believe that the electric power providers are ready with the weatherization changes that they’ve made,” Vegas said.

“Two, the operating changes that we’ve made in terms of how we utilize the operating reserves … that those processes are ready and that they’ve been executing well. And three, many of the communications changes that have been made are also ready: … how we let people know when we need a conservation and letting people know what’s going on the grid,” he added.

“The big takeaway is that [Brad’s] handing over ERCOT to me in a very prepared and ready condition to take on this winter and then to take on the Phase II market redesign, when we know what that’s going to be.”

Support for Staff

Not everything is running well at ERCOT. Vegas acknowledged morale is low among staff, saying “it has been a difficult couple of years for all our staff.” Indeed, the grid operator’s 12-month rolling attrition rate has climbed to 12.2%, up from 8.2% in August 2021.

“Responding to a terrible crisis like we came out of is extremely difficult for any organization to maintain that sustained level of operational critical readiness. Such a severe event can be very stressful on an organization,” Vegas said.

He said he will work to ensure ERCOT’s staff know they have the regulators and lawmakers behind them and that they’ve “done a phenomenal job of ensuring the ongoing reliability” through one of the market’s “most challenging summers.”

“They have passed the test with flying colors, and so they should feel good about that. They should feel good about the future because we’re going to continue to invest in the work that they’re doing,” Vegas said. “This next evolution of the market design is going to further deepen the ability to deliver the work that we do reliably, and to support the reliable operations of the grid. Those employees at ERCOT get to be a part of that team that is going to chart that future and how we’re going to solve the challenges that brings and to deliver the next generation of successful entrepreneurs.”

Texas Public Utility Commission Briefs: Sept. 29, 2022

PUC Adds Summer Requirements to Weatherization Rules

Texas regulators last week adopted expanded weather preparation rules for generators and transmission utilities during both summer and winter weather events, building on winterization rules passed last November following the devastating winter storm.

The order sets specific temperature standards for 10 geographically distinct areas in the state and establishes minimum and maximum temperatures at which generation owners and transmission utilities need to prepare their facilities to operate. The standards go into effect in 2023 (53401).

“The grid has to be ready for any weather condition, from extreme heat to extreme cold,” Public Utility Commission Chair Peter Lake said after Thursday’s open meeting. “These rules take that into account by setting the baseline preparation requirements for an operator at some of the most extreme weather conditions this state has experienced and requiring the operator to prepare their generation resources and transmission facilities to be able to operate in those conditions.”

Commissioner Will McAdams filed a memo before the meeting directing staff to add requirements that the industry account for wind chill in their cold-weather mitigation strategies. Power plants must weatherize their equipment to handle wind chills of 0 degrees Fahrenheit in most areas and temperatures of up to 96 F.

“I believe that given the cold weather conditions experienced in Texas during both 2011 and 2021, we should consider enhancing the staff-proposed rule by specifically accounting for wind chill based on a uniform weather zone-dependent standard,” McAdams wrote.

The expanded rule removes an exemption process adopted last year for utilities that could not meet mandatory preparation deadlines from supply chain issues or other acceptable reasons.

It also requires ERCOT to deliver a weather study that examines several weather parameters that can negatively affect the grid. The Texas grid operator must update this study at least every five years to account for variability in weather patterns.

The PUC also adopted a weather emergency preparedness report for the Texas Legislature that evaluated emergency operations plans developed by electric utilities, generators, municipally owned utilities, electric cooperatives and retail electric providers (53385).

The report’s authors reviewed 691 plans to identify best practices and assess the entities’ ability to manage emergencies from severe weather conditions and projected peak season conditions. They found 91% of the entities filed a complete report in a timely manner, the highest score among the seven criteria studied. Other criteria included emergency contacts (80%) and the plan’s content (69%).

PUC Appeals to SCOTUS

Following a closed session, the commission authorized its legal staff to appeal the 5th U.S. Circuit Court of Appeals’ recent decision siding with NextEra Energy’s challenge of Texas’ right-of-first-refusal legislation.

The 5th Circuit in August ruled the 2019 legislation (Senate Bill 1938) violates the U.S. Constitution’s dormant Commerce Clause. It remanded the case back to the U.S. District Court for Western Texas. (See 5th Circuit Finds in Favor of NextEra’s ROFR Appeal.)

The Texas Office of the Attorney General will represent the PUC in the appeal. As of Friday, a petition for review had yet to be filed with the Supreme Court, a commission spokesman said.

SCT Proceeding Closed

The PUC closed its oversight proceeding on the Southern Cross Transmission Project, saying it agreed with ERCOT’s solutions to its 14 directives to determine whether the proposed DC tie can safely interconnect with the Texas grid (46304).

The ERCOT Board of Directors in August endorsed the last three regulatory directives. The project has been under regulatory review since 2015. (See ERCOT Board Gives Southern Cross Project a Boost.)

“Is it fair to say that we, the regulators, have completed everything we can at this point in the process and are handing the baton to the private sector, to run with it as far as it can?” Lake asked Commissioner Jimmy Glotfelty, who responded in the affirmative.

“And that’s an important part of how Texas approaches regulation. We want to take care of business that needs to be done for reliability and for our consumers, and then hand it to the private market,” Lake said.

The Southern Cross project would build 400 miles of double-circuit 345-kV line that would be capable of carrying 2 GW of energy into the SERC Reliability region. SCT has FERC approval and a waiver from its jurisdiction, keeping ERCOT free of federal overview and maintaining its status as an island unto itself.

The PUC opened a new proceeding (54166) requiring regular updates from ERCOT on the project’s development. Coordination and SCT’s market participant agreements must be executed before the Texas side of the project can be energized.

Glotfelty Joins WEIM Regulatory Body

The commission accepted an invitation to join the CAISO Western Energy Imbalance Market’s (WEIM) Body of State Regulators, assigning Glotfelty to represent the state’s interests.

The group provides a forum for state regulators to learn about the WEIM and related CAISO developments “that may be relevant to their jurisdictional responsibilities.” It can express a common position on market issues in the ISO stakeholder process or to the WEIM’s Governing Body.

El Paso Electric is a WEIM member.

The now 12-member body is chaired by Thad LeVar, who also chairs Utah’s Public Service Commission.

Maryland: State Met 2020 GHG Emission Goal, but Behind on 2030

Maryland surpassed its greenhouse gas emission-reduction goal for 2020, according to the final data released by the state Department of the Environment.

According to the data, presented to the Maryland Commission on Climate Change during its quarterly meeting Sept. 27, emissions were down 30% below 2006 levels, beating out its aim to reduce GHGs released by 25% over the same period. Even accounting for the pandemic, which lowered expected pollution from motor vehicles, it is projected that emissions would have declined by 26% over the same period, still meeting the goal.

The most significant declines were in the energy sector, credited to the shift from coal to natural gas and renewable power generation. According to the department’s Vimal Amin, electricity-use emissions fell from approximately 43 MMT of carbon dioxide equivalent in 2006 to about 19 million in 2020.

“Two-thirds of our reductions from [2006] to [2020] have come from the electricity sector, and the reductions here are due to a combination of reduced electricity consumption, as well as changes in the generation mix, namely from replacement of coal-fired generation with natural gas and renewables,” Amin told the commission.

Despite the progress, Mark Stewart, climate change program manager for the department, said in-state clean energy generation lags behind being on track to meet the state’s Greenhouse Gas Emissions Reduction Act goals for 2030. One of the principal causes has been a backlog in reviews for new resources in PJM’s interconnection process.

“There’s been a backlog of projects receiving approval from PJM for connection to the grid, and a lot of these projects are renewable energy,” he said. “That PJM backlog has prevented the development of some projects. They’re working on a new system to fast-track some of those projects that are most ready to be implemented, so we’re optimistic that some of that backlog will be relieved within the next couple of years.”

The decline in energy sector emissions has left transportation as the state’s largest source of GHGs, at 35% of 2020 emissions, the majority of which is on-road vehicles. Amin noted that while the sector has also been seeing a general decline, the drop off going into 2020 is attributed to the COVID-19 pandemic.

The state is also currently lagging behind its 2030 goal of having about 800,000 electric vehicles registered in the state, which Stewart partly attributed to the pandemic reducing the inventory of new EVs on the market.

“On-road gasoline consumption is the biggest single source of emissions in Maryland, so we know the transition to zero-emission vehicles is a key component of the current climate plan and of future climate plans for Maryland,” he said.

Commission Reviews Federal Laws and Funding

The commission also evaluated the impact of the federal Inflation Reduction Act and Infrastructure Investment and Jobs Act on state emission goals, as well as how state and partner organizations are coordinating the use of federal funds.

William Ellis, vice president of government and external affairs at Pepco, said two provisions of the IIJA aim to provide resources for utilities to improve grid resilience under climate change. The utility is preparing concept papers that will allow for them to make applications once the submission period opens.

“It’s helping us to just think through and evaluate concepts related to those two topic areas. Some of the things that we’re thinking through are … undergrounding infrastructure, hardening our substations that could be impacted by climate change, as well as just creating a stronger and more resilient grid aimed at reducing outages through automation of controls, as well as enabling greater renewable penetration on the grid,” he said.

State Department of Transportation Deputy Secretary Earl Lewis Jr. noted that authorization of federal funds for the National Electric Vehicle Program was granted last month, allowing the state to go ahead with its work on installing EV charging stations at regular intervals along 23 identified alternative fuel corridors. (See FHWA Beats Sept. 30 Deadline for Approving States’ EV Charging Plans.)

“We’re working to expand Maryland’s robust electric vehicle charging infrastructure that currently has 1,266 charging stations and 3,475 charging outlets as of Aug. 31, 2022,” he said.

The state has also invested $436 million toward its ZEV program, bus pilots and electric bus procurements, with the first buses expected to arrive next year and a goal of converting half of its 700-bus fleet by 2030, Lewis outlined.

Maryland Energy Administration Chief of Staff Christopher Rice said his agency has been working with outside organizations to support their applications for federal aid, such as a $9 million carbon-capture entity paired with a cement factory; Montgomery County seeking 13 hydrogen fuel cell buses for $14.9 million; and a $22.9 million project with the Department of Labor to train workers for offshore wind installation and to upgrade Sparrows Point for OSW deployment. (See related story, Md. County’s Electric School Buses to Provide Synch Reserves for PJM.)

Stewart said that even with the new federal funds, the state’s shift to a goal of reducing emissions by 60% by 2031 under the Climate Solutions Now Act of 2022 leaves a gap in the trajectory of GHG reductions. One of the act’s provisions includes a 20-year global warming potential (GWP), rather than the prevailing 100-year model, which emphasizes GHGs that have a concentrated impact in their first few years after being emitted, most notably methane.

“The IRA did not end up being quite as ambitious as what we modeled last year as federal action, indicating that if we pair state [and] federal action under this framework, we’ll still have a lot of ground to cover to hit 60%,” Stewart said.

Ariz. Regulators Probe CAISO on EDAM, Heat Wave Operations

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px ‘Helvetica Neue’; color: #000000}

Arizona regulators say CAISO’s proposed extended day-ahead market could be a good opportunity for utilities in the state if issues of governance and resource adequacy are satisfactorily resolved.

“Independence of the governing structure is something that will be critical for Arizona,” said Arizona Corporation Commission (ACC) member Justin Olson. “If the CAISO can get that worked out where we have an independent governing structure, and they can address the resource adequacy policies in California, then the CAISO becomes a very attractive market for Arizona utilities.”

Commission Chairwoman Lea Marquez Peterson expressed similar views.

“An independent governance structure will be essential to my support,” Marquez Peterson said.

The comments came during a special ACC meeting on Sept. 21, where CAISO gave a presentation on its proposed extended day-ahead market.

CAISO runs the Western Energy Imbalance Market (WEIM), a voluntary, real-time market that was launched in 2014. Arizona utilities participating in WEIM include Arizona Public Service, Salt River Project and Tucson Electric Power (TEP), which joined in April.

CAISO is exploring an expansion of WEIM through an extended day-ahead market (EDAM). The ISO has been gathering stakeholder feedback on its plan and released a revised EDAM straw proposal in August. (See CAISO Updates EDAM Straw Proposal.)

In August 2021, an enhanced governance framework was approved for WEIM, in which decisions on certain issues are made through the joint authority of CAISO’s Board of Governors and WEIM’s Governing Body. The five members of the board of governors are nominated by the California governor and confirmed by the state Senate. The five members of the WEIM Governing Body are chosen through a stakeholder process, according to Stacey Crowley, CAISO’s vice president of external affairs.

Now, the WEIM’s stakeholder-run Governance Review Committee (GRC) has proposed extending the joint authority model to EDAM, Crowley said. GRC is asking for feedback on what types of decisions should be made through the joint authority.

Marquez Peterson said she’d like to see the joint authority widely applied.

“Ensuring that our voices are heard, and that we have the broadest extent of joint authority — that’s the direction I’d like to encourage,” she said.

Consequences Considered

Resource sufficiency is another issue being hammered out in the EDAM straw proposal. EDAM is not intended as a way for participants to bolster energy supplies when their own resources fall short, said CAISO COO Mark Rothleder. Instead, participants have more options for buying energy, potentially saving money.

The straw proposal would require EDAM participants to pass a day-ahead resource sufficiency evaluation (RSE).

“What exactly [do] you anticipate would be the policy if somebody does not have that day-ahead resource sufficiency?” Olson asked Rothleder.

Rothleder said two possible consequences are being discussed. One of those is a surcharge for failing to meet sufficiency requirements. In addition, he said, stakeholders are weighing whether there should be an “ultimate consequence” for resource insufficiency.

“If things go really bad, should you be able to still rely on those transfers, potentially impacting somebody else?” Rothleder said. “Potentially, the answer is ‘no.’ If you get in that position, and you’re not sufficient on your own, you shouldn’t be able to still rely on those transfers at the same level, or the same level of priority, as someone who did pass.”

Marquez Peterson asked what happens if CAISO is insufficient.

“If we are insufficient, we will follow the consequences,” Rothleder said.

Heat Wave Response

Rothleder also discussed CAISO’s response to the heat wave that scorched California from Sept. 5-9. Rolling blackouts were narrowly averted during the record-setting event, in which CAISO saw demand reach an all-time record of 52,061 MW on Sept. 6. (See California Runs on Fumes but Avoids Blackouts.)

Since the state’s rolling blackouts in August 2020, California has added more than 6,000 MW of capacity, including about 3,700 MW of battery storage. That capacity helped CAISO handle increased loads during the heat wave, Rothleder said. In addition, he said, coordination with other agencies has been improved.

And a few other factors worked in CAISO’s favor, Rothleder said. The heat wave hit the Pacific Northwest a bit earlier, taking some of the pressure off when high temperatures arrived farther south. Hydroelectricity was more available than usual for the time of year. And although temperatures in Arizona reached 107 or 108 degrees, the heat there wasn’t considered extreme, he said.

“This is very alarming to say the least,” Marquez Peterson said. “Without a moderate weather event in Arizona, California ratepayers would have been at public health and safety risk.”

In response to a question from Commissioner Sandra Kennedy, Rothleder acknowledged that CAISO was receiving emergency assistance from Arizona utilities and paying prices above $1,000/MWh.

Sam Rugel with TEP described the situation as “excellent for the ratepayers.”

“Being in the EIM, we were exporting throughout the day, day and night, into the Cal ISO market, in real time,” Rugel said. “And that does roll back to the ratepayers.”

But Rugel said the situation raises questions about resource adequacy.

“As much as this helps the neighbors … they should not be in this situation,” he said.

Regional Markets Explored

The ACC opened a docket last year for the purpose of investigating regional planning, markets and collaboration among load-serving entities in the Western Interconnection.

As part of its research, ACC heard a presentation in August from SPP on its Markets+ proposal, a program under development that will include a day-ahead market in the West.

In September, SPP announced that four Arizona utilities — Arizona Electric Power Cooperative, Arizona Public Service, Salt River Project and Tucson Electric Power — plan to support the next phase of Markets+ development. (See 4 Arizona Entities Commit to Developing SPP’s Markets+.)

ACC’s Utilities Division expects to file a report on regional planning and markets issues by the end of October.
