PJM PC/TEAC Briefs: July 13, 2017

PJM Maintaining Separate Load Peaks in Model

VALLEY FORGE, Pa. — The Planning Committee last week approved PJM’s recommendation to use 10-year historical data from 2003 to 2012 and to change the “world” peak week in its 2017 reserve requirement study.

PJM’s Patricio Rocha-Garrido told stakeholders the RTO decided to separate its peak load from that of the “rest of world” because of software limitations. Coincident peak distributions from the PJM load forecast cannot be used directly in its PRISM (probabilistic reliability index study model) software, which handles model uncertainty by week rather than day-by-day.

“The world” comprises of neighbors MISO, New York, the Tennessee Valley Authority and SERC Reliability’s VACAR region in Virginia and the Carolinas — areas from which the RTO would seek to import generation if it runs short.

(See “ISO-NE out of this ‘World,’ According to PJM Reserve Requirement Study,” PJM Planning Committee/TEAC Briefs.)

“When we have PJM and ‘the world’ peaking on the same week, effectively we’re having PJM and ‘the world’ peaking on the same day,” Rocha-Garrido said.

However, over the past 18 years, PJM and “the world” have peaked simultaneously eight times, while they have not peaked together 10 times.

In response, PJM moved the world peak to Week 11 in the summer and retained its peak on Week 10 to match the “historical diversity” in peaks.

Rocha-Garrido said the 2003-2012 load model, which was also used in last year’s study, was “a close second place” to the top-ranked 2004-2012 time period but had the advantage of an extra year of data.

“We do not see evidence to change that this year,” he said.

The recommendation was endorsed by acclamation, with no objections or abstentions.

RTEP Cycle Revisions Approved

The committee approved revisions to the rules for the Regional Transmission Expansion Plan, agreeing to extend the cycle from one year to 18 months.

PJM’s Amanda Long said the planning cycle will begin in September and run through February of the following calendar year. A new cycle will begin every September, overlapping the previous cycle. (See PJM Making Cost Consciousness a Focus for RTEP Redesign.)

The committee also approved Operating Agreement changes to extend the 30-day competitive proposal window for short-term projects to 60 days beginning about June annually. The long-term proposal window will remain at 120 days.

The proposal was endorsed by acclamation, with no objections or abstentions.

Resilience to Become Planning Driver

PJM’s Mark Sims explained how the RTO’s recent focus on resilience will impact its planning processes.

NERC’s standards require PJM to consider in its planning critical “stressed” conditions so it can manage the system regardless of actual conditions on any day. In addition, NERC requires the RTO to conduct a system assessment and explore potential solutions of low-probability “extreme” events.

As a result, Sims said, PJM will seek to identify “worst offenders,” such as circuits that frequently are involved in low-probability events. (See “PJM Reconsidering Planning Assumptions,” PJM Planning & Tx Expansion Advisory Committees Briefs.)

“It’s not involved in one low-probability event; it’s involved in many. So in my opinion, it’s no longer low-probability,” Sims said, adding that it “might” make sense to fix these issues.

John Farber of the Delaware Public Service Commission reiterated his concerns from a similar conversation during the Operating Committee meeting earlier in the week.

“There are major issues with implementing resilience as a standalone driver in the RTEP,” he said. “Achieving a sufficient level of objectivity to justify its inclusion as a standalone driver in the RTEP is just a difficult challenge to deal with.”

He said it will be difficult to develop objective cost and benefits criteria to justify millions in spending, especially when individual states may have different viewpoints on spending the money.

Greg Poulos of the Consumer Advocates of the PJM States agreed. Developing appropriate metrics will be important to determine how goals will be achieved, he said. The timeline is another issue, he said.

“There’s a lot of concern about things adding up,” he said. “I certainly agree it’s an evolution, but the consumer advocates are concerned it’s a slippery slope. Where does it begin and where does it end?”

Sims assured stakeholders it would be a “very deterministic” process. “I think this paradigm is going to be a little bit of a shift,” he said.

Winter Evaluation

PJM’s Tom Falin provided an update on the RTO’s analysis of winter resource adequacy and capacity requirements, the subject of an issue charge approved by stakeholders last year. The details highlighted the differences across the RTO. (See “Winter Resource Adequacy Analysis Raises Questions,” PJM Planning & Transmission Expansion Advisory Committee Briefs.)

An analysis of the ratio between the winter and summer peaks in each locational deliverability area (LDA) found that the East Kentucky Power Cooperative was the heaviest winter peaking LDA in the RTO, with a winter-summer ratio at about 1.3. The RTO itself is mostly summer peaking with a ratio of .87, and Rockland Electric is the heaviest summer-peaking LDA with a ratio of about .59.

“The heaviest summer-peaking LDAs are basically [in] New Jersey,” Falin said.

The loss-of-load expectation analysis results found that, even including the outliers from the winter of 2014-15 that included the polar vortex effects, and assuming historical forced outages and the maximum historical planned outages, the LOLE was .02 days/year. Falin noted that these numbers only included generator forced outages and that transmission outages would need to be considered as well.

Going forward, Falin said PJM will compute summer and winter reliability requirements for the RTO and selected LDAs while continuing to investigate a winter load forecast model.

Solar Capacity Factors Class Averages

PJM has updated its capacity factors for wind and solar based on actual summer data from 2014-2016.

PJM’s Jerry Bell said the analysis found that wind turbines have a capacity factor of 14.7% in mountainous terrain during peak summer hours between 3 and 6 p.m. and 17.6% in open, flat terrain during the same period. Solar capacity factors ranged from 60% for ground-mounted arrays that track the sun, to 42% for fixed ground-mounted panels, to 38% for all panel types other than ground-mounted.

The capacity factor affects generators’ capacity revenues and a project’s entitlement to capacity injection rights.

Renewable developers can request higher capacity factors for their projects if they can provide evidence to prove their generators operate at higher levels.

The study hasn’t yet considered how capacity factors are affected by degradation of the equipment over time, but Bell said it will be added in the future. Several stations were removed from the analysis because they displayed obvious degradation over time, he said. Degradation is, however, factored into CIRs for stations, he said.

Transmission Expansion Advisory Committee

Transmission Proposal Window Opens

PJM opened a 45-day window last week seeking proposed transmission projects to fix reliability criteria violations on 43 flowgates. The window will close on Aug. 25.

The flowgates were identified in the 2022 analysis: 34 in PJM’s Western Region, six in the Southern Region and three in the Mid-Atlantic Region. The remaining 161 flowgates from the analysis were excluded from the window as either immediate-need projects or under 200 kV, which is PJM’s threshold for opening projects to competitive bidding. The RTO has found that projects under 200 kV tend to be upgrades handled by the incumbent transmission owner.

Updates to AI Analysis

Staff have updated PJM’s beneficiary analysis for the Artificial Island project to address issues raised by stakeholders at the June 9 special Transmission Expansion Advisory Committee meeting. Among the additions was a list of transmission facilities that could compose a stability interface.

Most of the $280 million bill for the project would shift from Delaware to New Jersey and Pennsylvania under two alternative methodologies outlined in the analysis. But it will be up to PJM’s TOs to petition FERC to adopt a new methodology for the project. “PJM does not have the authority to devise or file allocation methodologies as federal law makes clear that the Section 205 filing rights over rates and cost allocation in this area rests with the PJM transmission owners,” the report says.

The project, PJM’s first foray into competitive bidding under FERC Order 1000, has been bogged down in stakeholder infighting for years. In April, PJM’s Board of Managers lifted a suspension on the project and re-awarded it to LS Power. (See PJM: AI Costs Would Shift to NJ, PA Under New Allocations.)

SPP Strategic Planning Committee Briefs: July 13, 2017

DENVER — The SPP Strategic Planning Committee last week directed RTO staff to move forward with a high-priority congestion study that earlier failed to gain traction in the Markets and Operations Policy Committee.

SPP Board Chair Jim Eckelberger suggested that staff incorporate suggestions from American Electric Power’s Richard Ross, who presented the MOPC with a new approach to determining why customers participating in the congestion-hedging market are not being allocated their full auction revenue rights and long-term congestion rights (LTCRs).

Under the AEP plan, staff would study the last cycle of hedge requests, identify unfulfilled requests, determine the effects of counterflow not requested in the ARR process and determine upgrades necessary to allow awarding of those unfulfilled requests.

“There’s significant congestion restricting service,” Ross said. “Members played by the rules, sought out firm service, paid for upgrades on the system, paid for Z2 credits, but still find themselves in a situation where they are paying for congestion because TCRs are not feasible.”

Ross’ approach would focus on the first round of the annual auction, where market participants seek the congestion paths most important to them.

“We use that information to figure out what upgrades are needed,” he said. “We need to go through this process to determine the bottlenecks and how to solve them. The motivation of the [market-clearing] engine is to maximize the clearing of those ARRs or TCRs. What happens is transmission requests or ARRs with small amounts end up eroding away the congestion hedges.”

Ross’ alternative approach was rejected by the MOPC, as was staff’s hybrid approach using some of AEP’s suggestions. Staff was directed to undertake the study addressing congestion in the Texas Panhandle and western Oklahoma during April’s Board of Directors meeting, when directors and members canceled a major 345-kV Southwestern Public Service project near Amarillo. (See SPP Board Cancels Panhandle Line, Seeks New Congestion Study.)

SPP staff are to report back to the board next week with their study assumptions and scope. The study is to be completed no later than April 2018.

During the MOPC meeting, members pushed back against the idea of another one-off study because SPP’s first assessment of future needs — part of its revamped transmission planning process — is due in October 2019.

Eckelberger said, “Let’s ask the staff to bring us back in two weeks its best proposals on how we can swing through this process, learn something and get us a product we can execute in the April time frame of next year, as opposed to waiting until October ’19.

“I’d say it’s pretty easy,” he said. “Don’t put anything in [that study] that’s speculative, like oncoming wind and solar. Use today’s gas prices, because we’re talking about something that works between now and a different approach in 2019.”

Eckelberger suggested to staff and the SPC that any assumption of new wind capacity above 4 to 5 GW with signed interconnection agreements is speculative.

“I don’t consider [the 4-5 GW] speculative,” he said. “I consider it real. It’s going to come by 2019 or 2020. Where it happens remains to be seen.”

The chairman received support from members. Westar Energy’s John Olsen said the congestion study’s April deadline would mesh well with SPP’s transmission planning and help the Economic Studies Working Group in preparing scenarios to be analyzed.

“That’s about the same time we go into heavy data gathering of the [planning study],” Olsen said. “It will be a great help to the ESWG as it determines the next round of futures. It’ll be a great way for them to have a head start on what the futures might look like, and where we need to go.”

SPC Approves Zonal Placement Process Document

The SPC approved minor edits to a process document that lays out the steps SPP must follow in making transmission zonal placement decisions, although the document does little to quell stakeholder objections about cost shifts within the process. (See Divide Evident Between SPP Tx Owners, Users.)

The Transmission Owner Zonal Placement Process document addresses the growth of transmission zones in SPP’s footprint and concerns expressed over the process in FERC proceedings. Since 2004, the RTO has gone from 15 pricing zones and 15 separate zonal annual transmission revenue requirement (ATRR) amounts to 18 pricing zones and 47 ATRR amounts.

“It’s a first step. Denise’s proposal was a first step,” said SPS’s Bill Grant, referring to Denise Buffington of Kansas City Power & Light, who submitted a revision request that was rejected by the MOPC. “There’s still a lot of work to do in this area. If we vote this and move it forward and think our work is done … it’s not even close to being done.”

“This is as good as we’re going to get,” SPP’s Michael Desselle said, noting the SPC had already decided it had done all it could with the zonal-placement issue. (See SPP Advances KCP&L Cost Shift Proposal.)

The process document spells out the following four steps:

      1. The applicant transmission owner (ATO) notifies SPP of its intent to transfer functional control of existing facilities to SPP and to file with FERC to recover the ATRR.
      2. SPP requests project information from the ATO upon notification.
      3. SPP performs integration analysis following a preliminary review of the ATO’s information. This step includes the RTO notifying TOs and network customers in zones into which the ATO could be integrated and providing them evaluation of cost shifts within 45 days after receiving the necessary information.
      4. Negotiation between the affected parties to discuss the zonal placement decision, potential cost shifts and any other resulting issues. The discussion period is limited to 45 days, with SPP available to facilitate if requested.

“I remain concerned because it doesn’t satisfy my concerns about lack of notice,” Buffington said, noting SPP gave an ATO entering KCP&L’s zone several alternatives before contacting the utility. “I understand SPP makes decisions on which zone to place someone, but when you talked to [the ATO], you showed them different options.”

“I’d really like your mindset to be looking out for your members and coordinating with your members,” Ross told SPP staff. “Don’t even look at it as ‘mother-may-I’ with someone who isn’t even part of system. Members who might be impacted should be your first thought, not your second.”

In the end, Grant and Nebraska Public Power District’s Traci Bender were the only members of the 14-person committee to vote against the motion. (Buffington is not a member of the SPC.) Kansas Electric Power Cooperative’s Les Evans abstained.

“I think this is a really good step forward,” said SPC Chair Mike Wise, of Golden Spread Electric Cooperative. “This gives a firm sense of the communication process.”

California Lawmakers Extend Cap-and-Trade

By Jason Fordney and Robert Mullin

California’s landmark program to combat climate change has received a new lease on life — 10 years, to be exact.

california greenhouse gas cap-and-trade
Brown | State if California

Both houses of the California State Legislature voted late Monday to extend the state’s greenhouse gas (GHG) cap-and-trade program until 2030 (AB-398). The bill now advances to the desk of Gov. Jerry Brown, a key supporter of the legislation.

“Tonight, California stood tall and, once again, boldly confronted the existential threat of our time,” Brown said in a statement. “Republicans and Democrats set aside their differences, came together and took courageous action. That’s what good government looks like.”

The outcome is a major victory in Brown’s efforts to ensure that California remains at the forefront of global environmental policy despite President Trump’s moves to roll back the previous administration’s measures to reduce carbon emissions.

Even better for Brown: Both the Senate and Assembly passed the legislation with more than two-thirds of members voting in favor. That margin should protect the bill from challengers who have argued that cap-and-trade constitutes a tax that requires supermajority approval under state law.

The state’s Supreme Court recently declined to review a court challenge by business groups. (See California High Court Upholds Cap-and-Trade.)

The cap-and-trade extension passed the state Senate 28-12, a single vote above the threshold needed to obtain a supermajority. Just one Republican — Sen. Tom Berryhill of Modesto — crossed the aisle to join Democrats who voted unanimously in favor of the measure. Assemblymembers voted 55-21 in favor, with seven Republicans and all but six Democrats — three no votes, two abstentions and one absence — in support.

The bill also mandates that large industrial facilities such as oil refineries upgrade emissions equipment by December 2023, and it increases penalties for pollution. It also requires emission reductions from mobile and stationary sources.

“Californians overwhelmingly support our efforts to tackle climate change; they know it’s an urgent threat and they want us to continue to lead. That’s exactly what we’re doing by extending cap-and-trade,” Senate President pro Tempore Kevin de Leòn said.

The cap-and-trade program will help the state meet its goal of reducing GHG emissions to 40% below 1990 levels by 2030, Brown’s office said last week in drumming up support for the bill.

The measure “extends the program by 10 years in the most cost-effective way possible,” according to Brown. It will ensure that carbon pollution decreases as the emissions cap declines and use of out-of-state carbon offsets is reduced; free carbon allowances will be reduced by more than 40% by 2030, he said.

Lawmakers on Monday also passed AB-617, a bill that provides for neighborhood air monitoring — an attempt to placate environmental justice groups that have been skeptical of cap-and-trade because it doesn’t directly address local pollution in low-income areas.

“The passage of AB-398 and AB-617 builds upon the momentum set forth by last year’s landmark climate change polices; establishing a comprehensive, statewide program that will allow us to achieve our ambitious climate goals, while ensuring the market stability necessary to retain industry jobs and address vital public health and air quality issues,” said Assembly member Eduardo Garcia, a sponsor of both bills.

The legislative package was “the product of weeks of discussions between the administration and legislative leaders with Republican and Democratic legislators, environmental justice advocates, environmental groups, utilities, industry and labor representatives, economists, agricultural and business organizations, faith leaders and local government officials,” Brown’s office said.

Under the cap-and-trade program, large GHG emitters must purchase emissions credits at the California Air Resource Board’s quarterly auctions to cover emissions not accounted for with free credits. Extending the program will keep auction proceeds flowing to environmental initiatives around the state, the governor’s office said.

“To date, these investments have preserved and restored tens of thousands of acres of open space, helped plant thousands of new trees, funded 30,000 energy-efficiency improvements in homes, expanded affordable housing, boosted public transit and helped over 100,000 Californians purchase zero-emission vehicles,” the office said.

Brown said he will continue to pursue climate change policies despite Trump’s pledge to withdraw from the Paris Agreement on climate change, which the president says is unfair to the U.S. Brown recently announced that California will host global leaders in September 2018 for a Global Climate Action Summit to support the agreement.

Brown last week also announced the “America’s Pledge” program with businessman and former New York City Mayor Michael Bloomberg. The governor’s office described the program as “a new initiative to compile and quantify the actions of states, cities and businesses in the United States to drive down their greenhouse gas emissions consistent with the goals of the Paris Agreement.” The initiative will produce a report on aggregate climate change commitments by states, cities, business and educational institutions, and a “roadmap for future climate change ambition.”

Trump Names Energy Lawyer McIntyre as FERC Chair

By Michael Brooks

The White House on Thursday announced that President Trump intends to nominate lawyer Kevin McIntyre as chairman of FERC.

The coleader of Jones Day’s energy practice in D.C., McIntyre has represented energy companies in litigation, compliance and enforcement matters and corporate transactions.

McIntyre, who has been rumored for months as Trump’s choice for the chair, would join more than a dozen other Jones Day alumni in the administration, including White House Counsel Don McGahn, a former Jones Day partner. Trump’s campaign reportedly has paid the firm $3.3 million in legal fees since 2015.

The White House said Trump will ask the Senate to confirm McIntyre for the remainder of former Chair Norman Bay’s term, which ends in 2018, and a full term ending in 2023.

McIntyre’s naming would fill the third Republican vacancy on the five-member commission, which could soon be restored to full strength.

Pennsylvania Public Utility Commissioner Robert Powelson and Neil Chatterjee, energy adviser to Senate Majority Leader Mitch McConnell (R-Ky.), both Republicans, have already advanced out of the Senate Energy and Natural Resources Committee and are awaiting confirmation votes by the full Senate. Trump has also said he intends to nominate Richard Glick, general counsel for the Democrats on the committee. (See Trump Taps Senate Aide, Former Lobbyist for FERC.)

Trump has yet to officially nominate Glick, however. And Chatterjee and Powelson are on a list of 44 others awaiting a confirmation vote.

The Senate has been mired in its effort to repeal the Affordable Care Act. McConnell on July 11 announced he would delay the chamber’s usual August recess for two weeks to ensure more time to complete action on legislation and nominations.

FERC has been down to one commissioner — acting Chair Cheryl LaFleur — since the departure of Commissioner Colette Honorable at the end of last month. It has been without the necessary three-person quorum since Bay left in February.

Acting FERC Chair Cheryl LaFleur (second from right) will be joined by four new members if Democrat Richard Glick (far right) and Republicans Kevin McIntyre (center), Robert Powelson (far left) and Neil Chatterjee win Senate confirmation.

The Natural Gas Supply Association and the Center for Liquefied Natural Gas released a joint statement praising McIntyre’s nomination but lamenting the amount of time it is taking to restore FERC’s quorum.

“Billions of dollars of investment and thousands of job opportunities in the U.S. continue to be sidelined by a lack of a quorum at FERC,” NGSA CEO Dena Wiggins said. “It is essential that the nominees be given the opportunity to be approved as quickly as possible.”

CLNG Executive Director Charlie Riedl added: “Restoring a quorum at FERC is essential to the LNG approval process, and we hope that Kevin McIntyre and the rest of the nominees will have their floor vote as soon as possible.”

EIM Leaders Endorse CAISO Gas Constraint Measure

By Jason Fordney

FOLSOM, Calif. — Western Energy Imbalance Market (EIM) leaders last week endorsed a CAISO proposal that would allow the ISO to constrain output from natural gas-fired plants across the EIM in response to potential restrictions on gas deliveries.

The five-member EIM Governing Body voted unanimously to approve applying to the entire EIM footprint the gas constraint developed by CAISO in the Aliso Canyon Gas-Electric Coordination Phase 3 straw proposal. That vote and other advisory decisions will go before the ISO’s Board of Governors later this month.

CAISO originally created the mechanism — which gives the grid operator authority to curtail output from plants in gas-constrained areas — to address reliability worries stemming from the outage at the Aliso Canyon gas storage facility. The latest proposal would extend that authority throughout the footprints of both the ISO and the EIM.

Restrictions on gas withdrawals from the 86-Bcf facility near Los Angeles have created supply concerns for power plants, and there are efforts underway to shut the facility down for good as residents still complain of health problems from the massive gas leak discovered there in October 2015. The California Public Utilities Commission is exploring closing the facility completely. (See Study to Weigh Aliso Canyon Shutdown.)

If FERC approves the plan sanctioned by the EIM body, the market tool will not expire in November as previously planned. CAISO said the tools will be in effect until it completes development of a set of commitment cost and default energy bid enhancements.

Greg Cook, CAISO’s director of market and infrastructure policy, told the body that there are continuing operational risks from the outage at Aliso Canyon. The constraints will address situations in which EIM gas-fired plants have limitations on the amount of gas they can burn in excess of what is scheduled, as well as when generators have limited firm pipeline capacity and additional capacity is not available when gas demand is high.

Governing Body Chair Douglas Howe questioned whether the program could create opportunities for market abuse and whether CAISO’s Department of Market Monitoring supported the measure. The department recently commented that the ISO had not fully justified the plan. (See Qualified Support for CAISO Gas Constraint Plan.)

“How convinced can we be that we won’t be opening up the door to market abuse in the EIM portion” outside CAISO? Howe asked.

There will be a well-vetted market process to make sure there is a legitimate physical constraint and opportunities are not created for market abuse or other unintended consequences, CAISO Vice President of Market and Infrastructure Development Keith Casey told Howe. The tools would only be used to manage physical supply problems on the system, not for economic purposes.

CAISO said it plans to follow a recommendation from the Monitor that it automate the process by which transmission paths are deemed uncompetitive, which triggers the mitigation measures.

The board yesterday also unanimously approved a proposal to include additional gas price indices to be used as a price threshold in the net benefits test, and changes to the board’s charter regarding its interaction with the Regional Issues Forum.

MISO Ponders Reserve Scheduling Fix

By Amanda Durish Cook

MISO is considering the possibility of factoring transmission constraints into its reserve requirement modeling to help prevent occurrences of scarcity pricing.

Staff are evaluating changing the algorithm underpinning the minimum zonal reserve requirement to reflect energy flow constraints. Under current practice, MISO calculates reserve requirements for a single operating day three days in advance using an offline study to produce results to be posted in time for the day-ahead market.

But actual operating conditions can change from original study assumptions, said MISO Senior Manager of Transmission Security Planning Mike Mattox, adding that the three-day modeling timeline has been in place for about 10 years.

Chatterjee | © RTO Insider

Dhiman Chatterjee, director of market evaluation and design, said a reserve model that does not capture constraints in the interim can unnecessarily create scarcity pricing for reserves.

MISO staff began taking notice of the issue after events occurring April 1, when an offline study predicted an 84-MW minimum contingency reserve requirement for Zone 6, which encompasses Indiana and a slice of Kentucky. In reality, more reserves were needed to compensate for generation and transmission outages in southeast Louisiana, including the shutdown of the Waterford 3 nuclear unit. As a result, Zone 6 experienced an outflow of energy to the south, triggering operating reserve scarcity conditions for 152 five-minute intervals during the day, with spinning and supplemental reserves clearing at about $200/MWh during 131 intervals and $1,100/MWh during 21 intervals.

“We’re really focusing on the event in April. We saw some relatively high prices for the reserves. … In this case, we saw it was bit counterintuitive so we dug into that,” said Chatterjee during a July 13 Market Subcommittee meeting.

MISO Principal Advisor of Market Development and Analysis Yonghong Chen said the constraints can be accounted for in the day-ahead modeling process to address reserve deliverability. Chen said that had the modeling more explicitly accounted for constraints, there would have been more inexpensive prices and a reduction in post-reserve deployment congestion.

“There is really no need to go into scarcity pricing,” Chen said.

Chatterjee said MISO is in the early stages of analyzing an additional modeling step that it could implement by the end of this year or early next year. He said staff would return to the subcommittee next month to update stakeholders on the feasibility of the change.

CAISO Monitor Says EIM Bid Limits No Longer Needed

By Jason Fordney

FOLSOM, Calif. — Energy transfer capacity in the Western Energy Imbalance Market (EIM) footprint is now sufficient to justify removing bid limits that are in effect for members PacifiCorp, NV Energy and Arizona Public Service, CAISO’s internal Market Monitor said last week.

Hildebrandt | © RTO Insider

Analysis by the Department of Market Monitoring found that EIM areas are structurally competitive during almost all intervals, Director of Market Monitoring Eric Hildebrandt said July 13 in a briefing to the EIM Governing Body at CAISO headquarters.

The power sellers are now limited to submitting EIM energy bids at or below cost-based default energy bids at all hours. They must get permission for the change from FERC, which requires companies joining the EIM to file for authority to charge market-based rates. PacifiCorp and NVE are both subsidiaries of Warren Buffett’s Berkshire Hathaway Energy.

“We are prepared to submit comments in support of the filing” to lift the restrictions, Hildebrandt said, noting that the Berkshire companies are potentially pivotal in a very small portion of intervals. Automated bid mitigation procedures effectively mitigate market power when imbalance demand is greater than transfer capacity, he said.

Under-mitigation in the 15-minute market, when congestion occurred but bid limits were not triggered as they should have, fell to 1.5% of intervals in the first half of 2017, compared with 17% a year earlier, he said. CAISO’s rules effectively limit the companies’ market power when EIM areas are not competitive.

The companies have been trying to get the mitigation measures lifted. They had argued that the measures imposed by FERC are out of proportion to the market power risks from imbalance energy, because of the small amount of load served by imbalance. They also said they have no incentive to exercise market power because they are large consumers of imbalance energy and would lose money if prices are too high.

But FERC cited market power concerns in May 2016 when it denied a request by NVE and PacifiCorp to rehear a previous decision that prohibited the two companies’ generating units from offering energy into the EIM at prices above default energy bids. (See Berkshire Denied Rehearing on EIM Market Power.)

Growth in EIM Transfer Capacity Has Increased Market Competitiveness, Monitor Says | CAISO Department of Market Monitoring

An economist with the Market Monitor said late last year that increased transfer capacity in the EIM is limiting congestion and reducing participants’ ability to use market power in their balancing authority areas. (See Increased Transfer Capacity Reducing EIM Congestion.)

FERC late last year also denied a request by NVE, PacifiCorp and 19 other Berkshire affiliates to rehear a decision prohibiting the companies from offering power at market-based rates in four neighboring balancing areas in the West, including the PacifiCorp East (PACE), PacifiCorp West (PACW), Idaho Power and NorthWestern Energy areas. The commission rebuffed the companies’ contention that an earlier ruling had denied them due process because it failed to notify them of “newly announced standards” for determining market power. (See FERC Upholds Berkshire Market-Based Rate Ruling.)

The EIM already includes the PACE and PACW areas, while Idaho Power is slated to join the market in April 2018.

NYPSC Extends Con Ed Demand Program

By Michael Kuser

ALBANY, N.Y. — The New York Public Service Commission last week approved an indefinite extension for Consolidated Edison’s demand management program in New York City’s Brooklyn and Queens boroughs, which aims to defer an estimated $1 billion in local infrastructure spending.

The commission’s July 13 order retains the original Brooklyn-Queens Demand Management (BQDM) program’s $200 million budget but caps expenditures on utility-side non-traditional solutions — such as storage batteries — at $50 million, including what the company has spent to date.

Con Ed has so far spent $46.56 million on the program, according to the most recent BQDM quarterly report.

The program allots Con Ed $200 million to procure market-based, distributed energy resource solutions such as energy efficiency, energy storage, distributed generation and demand response to achieve load reductions on the sub-transmission feeders supplying the company’s Brownsville No. 1 and No. 2 substations. The program aims at achieving 41 MW of customer-side DER and load reduction, as well as 11 MW of non-traditional utility-side solutions by summer 2018.

“In the absence of the BQDM program to meet the anticipated load growth in that area, Con Edison would have to construct a new distribution substation, a new switching station and substation feeders between the two,” Marco Padula, deputy director for market structure at the state’s Department of Public Service, told the commission. “This major project collectively was projected to cost approximately $1 billion.”

According to Padula, the program has provided Con Ed the flexibility to plan several infrastructure projects to be in service by summer 2019 and further delay the need for the new substation to 2026.

“Specifically, the additional solutions include the installation of capacitor banks, transformers and a 60-MW load transfer to the Glendale network,” Padula said. “With the extension, the company will have the opportunity to procure more DER that will allow it to delay the new substation and defer the need for the Glendale project and also enable possible future deferral for other traditional infrastructure projects.”

A New Normal

Newly appointed commission Chair John B. Rhodes lauded the successful concept design and Con Ed’s successful performance to date in meeting its implementation checkpoints on time and under budget.

“The BQDM program has also provided for important learning opportunities for other utilities, for stakeholders and for the commission, as non-wire alternatives have become part of New York state utilities’ standard business practices,” said Rhodes. “What was new has now become a normal.”

New York City supported the proposed extension in comments filed in April but wanted Con Ed to provide more detail on the cost-effectiveness of non-wire alternatives compared to traditional infrastructure investments. The city raised the possibility of doubling the utility’s incentives for some of the work performed under the program, specifically the Glendale project.

In response, the commission ordered that deferral of the Glendale project must be considered part of the BQDM program — and not as a separate non-wire alternative — that “shall not be eligible for further shareholder incentives beyond what has already been authorized.”

The commission also ordered Con Ed to continue filing quarterly reports and semi-annual cost-benefit analyses on the program, as well as an updated implementation and outreach plan reflecting the new realities inherent in the program’s extension.

The New York Battery & Energy Storage Technology Consortium also filed comments in support of the program, particularly its aspect of broadening the market for DER.

New York-based consultancy Peak Power, however, opposed it, as well as Con Ed’s methodology, load forecasting and auction procurement mechanism. Con Ed replied to all the parties’ comments in May and refuted Peak Power’s criticisms.

The extension order said the commission “does not agree with Peak Power’s characterization of Con Edison’s reporting on the BQDM program as being not transparent or that this proceeding lacks a record to support the company’s proposal.”

Commissioner Diane Burman alluded to criticism of the program but said that “reliability is paramount” and that it’s important to extend the program to avoid losing “the value that we see BQDM is providing.”

“We are seeing more of these [programs] from other utilities looking for similar non-wires alternatives and we’re even starting to see some non-pipes alternatives on the gas side,” Commissioner Greg Sayre added. “We make sure that each program that’s brought to us provides the benefit to ratepayers, compared to the traditional network investment, so we end up with a benefit to ratepayers, to the company and to the environment.”

Central Hudson Recovers REV Costs

The PSC also issued an order last week approving Central Hudson Gas & Electric’s deferral accounting authority and recovery of incremental costs associated with the state’s Reforming the Energy Vision (REV), which requires the state’s utilities to generate 50% of their energy from renewable resources by 2030. The commission’s order authorizes CHG&E to recover more than $1.8 million for incremental external labor costs associated with developing its distributed system implementation plan and related grid modernization efforts.

Michael Worden, DPS director of electric, gas and water, testified that the company incurred the costs as a direct result of commission orders for utilities to integrate DER into their systems and to develop interconnection portals to help facilitate DG interconnection.

“The utilities were also directed by the commission to develop hosting capacity analyses that are intended to identify more technically feasible locations on the distribution system where distributed generation projects could interconnect,” Worden said.

He pointed out that much, if not all, of the work represented in the order would have taken place through the natural process of grid modernization occurring prior to the REV proceeding.

“All of these efforts can be correlated to the increase in distributed resources that’s not only being seen in New York state, but nationally as well,” Worden said.

Burman said she understood “the need for Central Hudson to have regulatory certainty and clarity,” but she noted “that it is potentially cloudy in what it means, what is deemed reasonable and how they will be able to have cost recovery. … I don’t want this to be seen as there’s an unending pot of money for external labor.”

Illinois Zero-Emission Credit Suit Dismissed

By Rich Heidorn Jr

A federal judge on Friday dismissed challenges to Illinois’ zero-emission credit program, saying the customers and independent power producers who filed suit lacked standing and failed to exhaust their remedies at FERC.

U.S. District Court for the Northern District of Illinois Judge Manish S. Shah ruled in favor of motions by the state and Exelon to dismiss the case. “The ZEC program falls within Illinois’s reserved authority over generation facilities. Illinois has sufficiently separated ZECs from wholesale transactions such that the Federal Power Act does not pre-empt the state program,” the judge wrote in a 43-page opinion (17-cv-1163, 17-cv-1164).

The ZECs were authorized by the Future Energy Jobs Act, which the Illinois legislature approved in December after Exelon threatened to close its Clinton and Quad Cities nuclear plants. Following the bill’s signing, Exelon pledged to keep the plants — which it said had lost more than $800 million over the last six years — operating for another 10 years, saving 4,200 direct and secondary jobs.

2 Challenges Combined

The Electric Power Supply Association (EPSA) and members Calpine, Dynegy, Eastern Generation and NRG Energy filed suit in February, saying they stand to lose millions because the subsidized nuclear plants will suppress capacity and energy prices. (See IPPs File Challenge to Illinois Nuclear Subsidies.) The court combined EPSA’s suit with one filed by customers of Exelon’s Commonwealth Edison utility. Exelon intervened in both cases to defend the ZEC program.

On Monday, EPSA and its members filed an appeal with the 7th U.S. Circuit Court of Appeals. NRG spokesman David Gaier said the plaintiffs will ask for an expedited ruling. “If upheld, the Illinois decision would effectively strip FERC of its authority to regulate wholesale markets, would harm ratepayers, and threaten FERC’s ability to drive investment in energy infrastructure,” he said.

Initial briefs are due Aug. 28 under a schedule set by the 7th Circuit on Wednesday. Consolidated briefs are due by Sept. 27 and reply briefs by Oct. 27.

The suits both alleged the ZEC program violates the U.S. Constitution’s dormant Commerce Clause and that it is pre-empted by the Federal Power Act. The consumer plaintiffs also said the ZECs violated the Fourteenth Amendment’s Equal Protection Clause because only Illinois ratepayers will be billed to pay for the subsidy. The court cited an estimate that the ZECs will cost state ratepayers $235 million annually over 10 years.

Illinois modeled the ZECs on renewable energy credit programs enacted by Illinois and most other states, which have not been found to intrude on federal jurisdiction. The Illinois Power Agency will issue ZECs equal to 16% of the electricity delivered by each electric utility to retail customers in the state during calendar year 2014. Retail suppliers are required to purchase the ZECs under 10-year contracts ending May 31, 2027. The price for each ZEC is EPA’s social cost of carbon minus a “price adjustment,” based on energy and capacity prices.

Legal Tests

The Illinois suits raised state-federal jurisdictional issues similar to two cases the Supreme Court ruled on last year. In a January 2016 ruling, the court rejected EPSA’s challenge to FERC Order 745, upholding the commission’s jurisdiction over wholesale market operators’ compensation of demand response. (See Supreme Court Rejects MD Subsidy for CPV Plant.)

The same issues have been cited in EPSA’s federal court challenge to the New York’s ZEC program. (See related story, NY, Ill. Cite Allco Ruling in Defense of ZECs.)

EPSA and its members also have filed complaints asking FERC to subject the subsidized nuclear plants to the minimum offer price rule (MOPR) in capacity market auctions.

Plaintiffs’ Standing

In evaluating the motions to dismiss, the court assumed the facts represented by the plaintiffs were true; the case was terminated without any fact finding on the “injuries” the plaintiffs claimed.

To establish the right to sue under Article III of the Constitution, Shah said the plaintiffs must show an “injury in fact” that is “fairly traceable” to Illinois’ conduct and can be fixed by the court. Shah ruled that the plaintiffs lacked Article III standing to challenge the price adjustment, noting Exelon’s observation that eliminating the price adjustment would result in the ZECs being priced at the social cost of carbon. “The injury caused by the ZEC subsidy is not traceable to the price adjustment, because that injury would exist even if the statute were cured of its ties to wholesale auction prices,” Shah ruled.

The judge also ruled the consumers did not have statutory standing for their complaint because the states have authority to regulate retail sales, making the retail surcharge funding the ZECs “outside of the zone of interests of the federal statutes.”

Dormant Commerce Clause

The court was no more sympathetic to the generators’ dormant Commerce Clause claim that the ZECs favor the Clinton and Quad Cities nuclear plants and discriminate against nuclear generators outside the state. “Regardless of whether ZEC recipients are in Illinois or not, the generator plaintiffs’ injury from lower wholesale prices remains the same, and the consumer plaintiffs will receive higher bills,” the judge said. “Since plaintiffs’ injuries are not traceable to the alleged in-state favoritism, they do not have Article III standing to challenge it.”

Shah said the validity of dormant Commerce Clause claims “turn on a ‘sensitive, case-by-case analysis’ of the facts, including the ‘purposes and effects’ of the law at issue.”

“Where the statute regulates even-handedly to effectuate a legitimate local public interest, and its effects on interstate commerce are only incidental, it will be upheld unless the burden imposed on such commerce is clearly excessive in relation to the putative local benefits,” he said. “The governor’s and some legislators’ celebratory remarks about the potential job-saving effects of the law do not negate the ZEC program’s environmental purpose and public health interests.”

Pre-emption

The plaintiffs had asked for an injunction to block the ZECs on the grounds that the program is pre-empted by FERC’s authority under the Federal Power Act. Shah ruled the FPA makes FERC responsible for adjudicating such issues and generally does not authorize private causes of action.

“Parties can bring a complaint to FERC if they believe a practice interferes with the markets or creates unjust or unreasonable rates or practices; FERC can take corrective actions to ensure that wholesale rates and practices remain just and reasonable; and parties that disagree with FERC’s decision can seek review in the circuit courts,” Shah said. “A coherent regulatory policy for interstate electricity markets is a desirable outcome, and it is one that private suits undermine.”

He also said the EPSA and Hughes rulings found that “pre-emption applies whenever a tether to wholesale rates is indistinguishable from a direct effect on wholesale rates.”

“The qualifier ‘direct’ is important; influencing the market by subsidizing a participant, without subsidizing the actual wholesale transaction, is indirect and not pre-empted,” he continued. “Since a generator can receive ZECs for producing electricity and the credits are not directly conditioned on clearing wholesale auctions, ZEC payments do not suffer from the ‘fatal defect’ in Hughes.”

Shah also said FERC was equipped to respond to any “market distortion” resulting from the nuclear subsidies. The plaintiffs’ contention that Illinois’ program conflicts with FERC’s preference for competitive auctions is “too broad a theory of pre-emption and would inappropriately limit state authority,” he said.

“So long as FERC can address any problem the ZEC program creates with respect to just and reasonable wholesale rates — and nothing in the complaints suggest that FERC is hobbled in any way by the state statute — there is no conflict,” he said. “The complaint … does not allege that FERC is damaged in its ability to determine just and reasonable rates. The regulatory structure remains unaltered, and FERC’s power undiminished. Consequently, the ZEC program does not conflict with the Federal Power Act.”

Shah’s ruling on this point appears to differ from the Supreme Court’s ruling in Hughes, which saidMaryland cannot regulate in a domain Congress assigned to FERC and then require FERC to accommodate Maryland’s intrusion.” In that case, however, the court ruled that Maryland’s contract for differences subsidy directly and improperly tied the generator’s compensation to PJM capacity market prices.

Equal Protection Claim

Also rejected was the consumers’ complaint that they were being discriminated against because only Illinois ratepayers would fund the ZECs. “The Constitution only requires Illinois to treat equally the people within its jurisdiction. As such, Illinois does not run afoul of the Fourteenth Amendment by treating Illinoisans differently from citizens from other states that live in the MISO or PJM regions,” Shah said. “Furthermore, the complaint does not allege that Illinois could have imposed a surcharge on people in the MISO and PJM regions that lived outside of Illinois.”

The judge noted that courts usually allow plaintiffs to amend a complaint after an initial dismissal. “Here, however, the deficiencies in plaintiffs’ claims cannot be cured with different allegations,” he said. “These plaintiffs cannot pursue the legal theories they have articulated (or they do not have standing to do so). Therefore, I decline to give them leave to amend.”

Divide Evident Between SPP Tx Owners, Users

By Tom Kleckner

DENVER — The divisions between SPP’s transmission owners and their customers could not have been starker than they were during the Markets and Operations Policy Committee meeting last week.

Twice, load-serving transmission owners overwhelmingly endorsed voting items favorable to their customers and companies. One was a revision to SPP’s transmission zone placement process. The second was a motion to reject staff’s recommended scope for a high-priority study that didn’t address their concerns with the RTO’s transmission planning process, which they say hasn’t resolved systematic congestion on certain parts of the system.

Both times, the larger number of transmission-using members — 77 of the committee’s 95 voting members — resulted in the TOs coming up on the short end after hours of back-and-forth comments.

“We had a good discussion. I’ll leave it at that,” MOPC Chair Paul Malone, of the Nebraska Public Power District, told the Strategic Planning Committee during its post-MOPC meeting Thursday.

Transmission Planning Process

Large load-serving entities complain that they are footing most of the bill for transmission expansions that also benefit transmission developers, wind developers and small municipal utilities and cooperatives.

Several members questioned the need for the high-priority study of congestion in the Texas Panhandle and western Oklahoma, pointing to recent changes to SPP’s transmission planning process. Staff have streamlined the number of assessments into a single 10-year study that will produce an annual expansion plan addressing reliability, economic and policy needs. The process’s first results will be shared in October 2019. (See “SPC, MOPC Approve Improvements to SPP’s Tx Planning Process,” SPP Strategic Planning Committee Briefs.)

A frustrated Greg McAuley of Oklahoma Gas & Electric told the MOPC that while the TOs weren’t in lockstep, they all want to protect customers from additional costs.

“What you see are those that have companies that have to pay for these things are being outvoted. That’s a concern this organization needs to reconsider,” McAuley said. “Our customers have just paid for [transmission planning process] improvements. What I’m hearing today is we’re asking [our customers] to pay another million dollars for another ad hoc study, because our process does not work.”

Transmission Zonal Placement

Kansas City Power & Light’s Denise Buffington, who shepherded the zonal-placement revision request (RR172), tried to take the MOPC’s rejection of her proposal in stride. While waiting for a runner to bring her a microphone during the SPC’s discussion of the proposal, she asked wryly, “Can I just scream?”

Buffington urged board members in attendance to consider adding additional municipalities and cities as members besides the large membership expansions, such as the Integrated System and Mountain West Transmission Group.

“Obviously, the votes that happened at MOPC show those that are paying the bills have less of a vote than those that aren’t paying the bills,” she said. “I encourage you to consider in your strategic-analysis plan all types of membership expansion that affects the pool and members.”

The load-serving TOs approved Buffington’s revision request by a 15-3 margin, with the Basin Electric and Western Farmers cooperatives joining Grand River Dam Authority in opposing it. However, the transmission-using owners voted down the motion 30-12, with seven abstentions, leaving the proposal 11 percentage points short of the necessary 66% approval.

“I just want to put everyone on notice that we will be appealing to the board,” Buffington said immediately after the vote. The Board of Directors and Members Committee meets July 25 in Denver.

“Shocker!” responded Heather Starnes, legal counsel for the Missouri Joint Municipal Electric Utility Commission and a nay vote.

Buffington has been working on RR172 for two and a half years to address what she says is a gap in the SPP Tariff.

Staff currently determine which of 18 transmission pricing zones to place new TOs in, which can result in cost shifts for those in the incumbent zone. (See SPP Advances KCP&L Cost Shift Proposal.)

The revision request was modified after “robust” stakeholder debate at the SPC and Regional Tariff Working Group, Buffington said. She said the modified RR172 is a “middle ground” and improves transparency in the new member zonal placement decisions by providing advance notice to TOs and their customers, allowing potentially affected entities to provide feedback before SPP makes a decision.

Buffington said RR172 also mitigates costs of zonal-placement decisions and protects both existing and new customers from cost shifts.

“This RR is primarily focused on the cost-shift issue … when SPP creates or expands multi-owner zones,” Buffington said. “KCPL has tried to come up with compromise but hasn’t been able to gain consensus. The alternative is litigation. To me, that’s a lot of risk on both parties.”

Some of those opposing the measure said there wasn’t enough time to study the revisions to the proposal. Others questioned whether the MOPC should be voting on a Tariff change without any working group’s approval. Some cited the “radical new policies” network customers would face in becoming TOs and fears of encroaching on FERC’s rate-setting authority.

“Does this group, as a Markets and Operations Policy Committee, really want to pass a Tariff revision when FERC should be the decision-maker? Rates are in the FERC purview,” said South Central MCN’s Brett Hooton. “We’ve had a lot of long SPC meetings on this topic. I don’t know that rehashing all that is going to change anyone’s opinion today.”

Starnes agreed with Hooton.

“We’ve beaten this horse until it’s bloody and no one recognizes it anymore,” she said, calling for the vote.
