ISO-NE Again Defends Capacity Auctions

By William Opalka

ISO-NE CEO Gordon van Welie last week again defended the RTO’s capacity auction to congressmen who say market practices have led to inflated electricity rates for New England ratepayers.

In an eight-page, single-spaced letter sent Monday, van Welie reminded the New England congressional delegation of his testimony three years ago that highlighted the dramatic shift in the region’s market.

“Since then, 4,200 MW of resources have either announced plans to retire or have actually retired. Importantly, since 2013, the region’s Forward Capacity Market (FCM) has procured over 4,700 MW of new capacity resources — demonstrating that the FCM is procuring new, economically competitive resources to meet the region’s energy needs,” he wrote. (See Prices Down 26% in ISO-NE Capacity Auction.)

Van Welie’s letter was a response to a March 14 letter sent to FERC and the RTO by the delegation members after results of the 10th Forward Capacity Auction were filed.

“While these clearing prices were the result of a ‘competitive auction’ according to ISO-NE, the results are roughly equal to FCA 8, an auction that triggered administrative pricing rules due to lack of competition. They are also triple the capacity payments derived from the auctions prior to FCA 8,” the delegation wrote.

The congressmen acknowledged that prices declined more than 25% from FCA 9, but they noted that the previous year was a record $4 billion.

Ten senators and representatives joined in the letter, which was written by Massachusetts Democrats Rep. Joseph P. Kennedy III and Sen. Edward Markey. The members have repeatedly complained to FERC, without success, about alleged market manipulation. (See Congressional Meeting Fails to Sway LaFleur on Capacity Results.)

Van Welie said that market participants respond to price signals.

“We share your goal of ensuring that prices in the capacity market are just and reasonable. The FCM must and does signal the true value of capacity in New England. Artificial prices (whether too high or too low) do not benefit regional electric reliability or New England residents,” he wrote.

ERCOT Stakeholders Agree on Lost Opportunity Costs Rule

By Tom Kleckner

AUSTIN, Texas — ERCOT’s Technical Advisory Committee last week agreed on a method for paying lost opportunity costs to generators ordered to ramp down for grid reliability, a solution that will now go to the ISO’s Board of Directors.

Stakeholders discussed three options brought forth by ERCOT staff to address Nodal Protocol Revision Request 649 (Addressing Issues Surrounding High Dispatch Limit (HDL) Overrides), which was remanded back to TAC during the board’s February meeting. (See LOC Rule Sent Back to ERCOT’s Stakeholder Process.)

Staff’s preferred option was the first of three it presented: rewriting the NPRR’s language to replace compensation for opportunity costs with “justified” losses suffered by qualified scheduling entities (QSEs) holding existing contracts. The QSEs would have to provide an attestation of loss, calculations and supporting documentation to recover a claim.

A second option proposed software changes to override the resource node’s LMP, which would have created difficulties at the 98 nodes with at least two generator connections. The third, and priciest option, at $200,000 to $300,000 plus ongoing support, would pre-position manual constraints associated with each resource node in the system model.

As the discussion wore on, it became apparent stakeholders were coalescing on the first of ERCOT’s options.

“This seems to be a quickly diminishing issue,” said Shell Energy’s Greg Thurnher, representing independent power marketers. “It looks like Option 1 is the remedy.”

Brandon-Whittle,-Megawatt-Analytics-web — Whittle

“We think Option 1 is the way to go for now,” said Megawatt Analytics’ Brandon Whittle, speaking for Odessa-Ector Power Partners and Koch Services. “It puts the onus on the people who might get hurt. No generator wants to be paid back for their losses because of HDL overrides. We’d rather adjust the LMPs.”

The proposal passed by a 23-5 vote, with two abstentions. The NPRR will go before ERCOT’s board April 19. Staff will revise the revision request’s impact analysis and better define energy bilateral contracts.

Odessa-Ector, a subsidiary of Koch Ag & Energy Solutions, initiated discussion of the issue when it claimed its combined cycle plant had lost $300,000 because of three days of dispatch overrides in November 2012. ERCOT submitted the NPRR to satisfy a settlement agreement with Odessa-Ector after the company filed a complaint with the Public Utility Commission of Texas (docket #41790).

Luminant’s Amanda Frazier expressed a preference for an earlier version of the NPRR, which failed to secure sufficient votes. But she said that in subsequent discussions, “ERCOT has eliminated a number of concerns we originally had.

“The damages are limited to those attested to by the resources, and compensating the actual damages rather than the opportunity costs is a good compromise,” she said.

Resmi Surendran, ERCOT senior manager of market analytics and design, highlighted staff’s efforts to reduce HDL overrides, which peaked at more than 348,000 minutes in 2011. The numbers have steadily dropped since then, with only 57 minutes of overrides recorded last year.

Surendran attributed the improved results to increased operator training, their ability to enter manual constraints, the availability of new generic transmission constraints and topology improvements.

Whittle sought reassurance from ERCOT that the NPRR’s cost can be reduced from its current staff estimate of $100,000 to $150,000.

“We try to implement [any changes] at the minimum cost we can,” said Kenan Ögelman, ERCOT’s vice president of commercial operations. “We’ll definitely go back and see if we can’t reduce the cost. I just can’t give you a number, right now.”

SPP Briefs: State of the Market, Study w/ AECI

The SPP Market Monitoring Unit’s State of the Market report for the winter months once again highlighted wind generation’s growing importance within the RTO’s footprint.

According to the report, which covered December 2015 through February 2016, wind generation accounted for 17.7% of SPP’s energy, a 43% increase from last winter. Wind generation accounted for 12.4% of energy production last winter and 10.2% during the winter of 2014.

As if to punctuate the point, SPP set a new wind peak during the evening hours of March 28, shortly after the market report was released. The RTO’s new wind peak of 10,809 MW at 9:22 p.m. CT broke the previous record of 10,783 MW, set March 21. Wind penetration reached 40.34% March 28, short of the 41.1% high set March 7.

Wind generation peaked in February, producing nearly 21% of SPP’s energy, according to the Monitor’s report. SPP has 12,397 MW of installed and available wind capacity in its footprint, with another 33,819 MW in various stages of development.

The increase in wind power came at the expense of coal generation, which saw the percentage of energy it produced fall to 46.3% for the month, down from 57% in February 2015.

The report said the increase in wind generation “comes [with] an increase in congestion.” Most congestion in the SPP footprint can be found in the “wind alley” of the Texas Panhandle, western Oklahoma and western Kansas.

The Monitor measures congestion by a constraint’s shadow price, “which reflects the intensity of congestion on the path represented by the flowgate.” It said the shadow price “indicates the marginal value of an additional megawatt of relief on a constraint in reducing the total production costs.”

Shadow prices reached almost $60/MWh on one flowgate and topped $40/MWh on at least two other flowgates.

The Monitor report also said gas costs continued to drop during the winter, with an average Panhandle Hub cost of $1.98/MMBtu, more than 30% lower than 2015 ($2.90/MMBtu) and nearly two-thirds lower than 2014 ($5.68/MMBtu).

The average real-time balancing market’s winter 2016 LMP was $17.82/MWh, down from $25.20/MWh in 2015. The day-ahead market’s average LMP was $18.33/MWh, down from $25.73/MWh last winter.

SPP, AECI Begin Biennial Joint-Study Process

SPP and Associated Electric Cooperative Inc. (AECI) began their biennial joint-study process with a call for stakeholder feedback and input on a proposed scope last week.

The SPP-AECI Interregional Stakeholder Advisory Committee (IPSAC) has identified several voltage and congestion issues in Missouri and Oklahoma, but the committee said April 1 it is giving stakeholders two to three weeks to comment on the scope. A separate meeting will be scheduled for the study scope’s formal endorsement.

The IPSAC will evaluate the SPP and AECI transmission systems and determine whether “mutually beneficial” joint projects exist. A joint planning committee comprising a representative from each staff will determine cost allocations on a case-by-case basis, with responsibility “assigned equitably” based on the constraint being resolved — and subject to approval of each region.

The two entities have been performing joint studies every other year since 2010, as outlined in their joint operating agreement. The 2014 study identified 463 potential needs along the SPP-AECI seam but resulted in no joint solutions.

Stakeholders asked staff whether this study might solve long-standing constraints in the Lake of the Ozarks region in central Missouri.

“We studied some alternatives in the last joint-study process related to a 345[-kV line] across this lakes area, but we did not see a lot of economic value or immediate reliability concerns a line across that area would solve,” said David Kelley, SPP’s director of interregional relations. “But constraints obviously move around, so we’re always willing to look at an alternative.”

James Vermillion, a senior planning engineer for AECI, said the association’s latest 10-year Long Range Transmission Plan has identified almost $40 million in improvements to maintain grid reliability. Still, that is down from the 2009-19 plan, which identified more than $221 million in projects.

AECI, based in Springfield, Mo., is owned by and provides wholesale power to six regional generation and transmission cooperatives.

Peabody, Arch Announce 465 Layoffs at 2 Wyo. Coal Mines

The two largest coal mines in the U.S., both in Wyoming, announced massive layoffs last week. Peabody Energy cut 235 people, or 15% of the workforce, March 31 at North Antelope Rochelle. Arch Coal said the same day it was cutting 15%, or 230 people, at its Black Thunder Mine.

Until now, Wyoming’s coal industry has largely avoided the massive cutbacks seen in Appalachian coal operations. The two mines, which produce about 100 million tons of coal a year, are generally regarded as among the most cost-effective mines in the country.

PacifiCorp to Close Coal Unit At Wyoming’s Kemmerer Plant

PacifiCorp has abandoned plans to convert a coal unit at its Naughton Plant in southwestern Wyoming to natural gas, saying it will now retire the unit at the end of 2017. The company said the move is a result of declining electricity demand and reflects the costs of installing environmental upgrades to meet federal haze requirements.

PacifiCorp’s initial plan had been to shutter Unit 3 for five months, starting at the end of 2017, and convert it to natural gas. The estimated cost of the conversion was $160 million. Natural gas had been a cheaper option for complying with regional haze requirements than upgrading the unit’s coal burning equipment under the Oregon-based utility’s initial calculations.

Berkshire Power Pleads Guilty To Emissions Violations

Berkshire Power, the operator of a Western Massachusetts power plant, has agreed to plead guilty and pay $8.5 million for tampering with air pollution monitoring equipment and reporting false data about emissions levels.

Federal prosecutors say that employees at Berkshire Power in Agawam, Mass., manipulated the emissions monitoring system between January 2009 and March 2011 to conceal excess emissions. The actions were violations of the federal Clean Air Act.

The plant’s managers also violated the Federal Power Act for lying to ISO-NE about the plant’s availability to produce power, the first-ever criminal charges under that statute, according to the Justice Department.

MISO Proposes 3 New MTEP 17 Futures

By Amanda Durish Cook

MISO last week proposed the adoption of three new future scenarios intended to inform the development of the 2017 Transmission Expansion Plan (MTEP 17).

Jenell McKay, a MISO senior analyst, told participants at a March 30 workshop that stakeholders are seeking a “range of modeling futures and some form of carbon reduction modeling” to assist in the planning cycle.

The three retooled “futures” include:

An “existing fleet” narrative in which MISO’s generation fleet is largely unchanged because of low demand and no carbon regulations are modeled. Already-planned coal retirements are factored into the scenario, and remaining coal units retire only after reaching their 65-year age limits. MISO also assumes renewable tax credits will expire in 2022, existing nuclear units will stay online and low natural gas prices and a stagnant economy curb renewable growth. As a result, gross aggregate demand grows at just 0.3 to 0.4%, and the energy growth rate is similarly low at 0.4 to 0.5%.
A “policy regulation” future based on the final Clean Power Plan rule, with a 25% reduction of carbon emissions across MISO, which drives 16 GW of coal retirements and increased reliance on mid-range-priced natural gas. MISO also assumes that nuclear units remain online and non-nuclear, non-coal generators retire according to 55-year age limits. Aggregate demand grows at the current 0.8 to 0.9% rate, while energy growth hovers around 0.7 to 0.9%.
An “accelerated alternative technologies” future in which a “robust” economy propels expanded demand, leading to a 35% carbon reduction and steering MISO to 24 GW worth of coal retirements. This future assumes high natural gas prices, retirement of non-nuclear, non-coal generators at 55-year age limits, license renewals for nuclear units and continuation of renewable tax credits beyond 2022. Aggregate demand and energy consumption growth rates both surpass 1% under the scenario.

To address stakeholder concerns about price volatility, all future scenarios assume a 30% variance between high and low natural gas prices during the study period. McKay said assumptions about storage technologies were not included in any of the narratives but could be inserted during an “R&D phase” over the next few months.

In response to several questions about why MISO is not modeling a business-as-usual case for MTEP 17, McKay responded that industry uncertainties about carbon regulation, coal retirements and renewable penetration made a definite BAU scenario elusive. “We didn’t feel comfortable calling anything business-as-usual,” she said. “For instance, if the CPP is upheld [following court challenges], the policy regulation future will be the business-as-usual case.”

Matt Ellis, MISO manager of policy studies, said stakeholders can still weigh in on the futures. “Do they pass a smell test? Are they reflecting what’s already happening on your factory floors?” he asked.

MISO hopes to continue discussion about the futures at an April 20 Planning Advisory Committee before putting them to a vote at the May PAC meeting.

OMS Asked to Back Modeling Allowance Auction

Meanwhile, the Organization of MISO States could urge MISO to model a carbon emissions allowance auction after being approached by the Coalition of MISO Transmission Customers about the issue last week.

Coalition representative Robert Weishaar told a March 31 OMS meeting that he raised the issue with MISO staff, who he said were “reluctant” to model the net cost of CPP CO₂ allowances that are auctioned rather than allocated.

Weishaar said he was not advocating an auction over an allocation but wanted to see both hypotheticals in MISO’s CPP modeling. “We’ve taken a particularly critical interest in MISO CPP modeling to date,” he said.

Calling the omission a “gap in the MISO modeling approach,” Weishaar asked for OMS’ support in endorsing a future letter on the matter.

Libby Jacobs of the Iowa Utilities Board said she would support such a letter, but other OMS members expressed indifference.

Texas Public Utility Commissioner Ken Anderson said an auction may affect generator dispatches and the fuel mix, but those points were moot. “Because we’re in the ‘just say no’ camp to the CPP, we’re not particularly interested in MISO modeling,” Anderson said.

How Utility Conservatism is Hampering Tx Innovation

By Rich Heidorn Jr.

WASHINGTON — Risk-averse engineers and outdated utility ratemaking structures are preventing quicker deployment of innovative technologies that could avoid transmission line rebuilds and save money, speakers told the Infocast Transmission Summit last week.

The discussion came in a session on how technologies such as dynamic line ratings, phasor measurement units and HVDC can increase the capacity of existing rights of way.

McCall © RTO Insider (utility, transmission) — McCall © RTO Insider)

Jack McCall, vice president of sales for Lindsey Manufacturing, likened DLRs and PMUs to technologies that can increase vehicle speeds on a curvy highway: PMUs are like Ferraris, which can take curves at high speeds; DLR, he said, is like straightening the road.

Gregg Rotenberg, president of Smart Wires, quoted former Southern Co. CEO David Ratcliffe, who said there are three types of transmission organizations: ostriches, who choose to ignore change; deer, who are frozen in place by change; and lions, who will seek to capitalize on the change and “are going to eat a bunch of ostrich and deer.”

Ali Amirali, senior vice president of private equity fund Starwood Energy Group Global, offered a fourth type: cats, who are indifferent to change. He cited the Bonneville Power Administration, which he said views its mission as delivering hydropower to preferred customers and does not seek to maximize the capacity of the system because it’s not part of the agency’s “mandate.”

“And they curtail wind all the time,” interjected Hudson Gilmer, vice president of commercial markets for Genscape.

DLRs, which can measure conductor temperature, sag and line capacity, as well as detect icing and “galloping” — high-amplitude, low-frequency oscillation caused by wind — have been available for more than a decade, but early applications required scheduling an outage and deployment of bucket trucks and crews. “And once it was on a line, congestion is almost like whack-a-mole; it moves around on your network,” Gilmer said. “And then it’s very hard to get [operations and maintenance] dollars to move it to a new place.”

“If you look back over the last 10 to 20 years, there have been so many studies done both in North America and elsewhere in the world that show that dynamic line rating truly does expose easily 10% to 25% additional capacity on any transmission line almost on a regular basis,” added McCall. “It’s a very low-hanging fruit.”

Newer DLR technologies, such as those sold by Genscape and Lindsey, are easier to install but still face institutional inertia.

(utility, transmission) — Amirali *© RTO Insider*

“Why do we not have real-time monitoring? … It’s not the technology. It is the policies. It is the standards. It is the personnel and it’s the decision making,” Amirali said.

“The people who are running the grid — me included, [a] former operator — are about the most conservative people on Earth,” he continued. “We are trained to be conservative. Because [if] an engineer takes a risk and he’s successful, nobody really knows about it [because] the system operates the way it was supposed to. We take a risk and we fail: Chernobyl!”

The resistance to change also is a function of utilities’ organizational structures and revenue models, speakers said.

“Risk doesn’t stop us from doing deals,” Rotenberg said. “The bigger challenge is those transmission organizations who choose to look at all the risk in front of them in terms of how fast the world is changing, how fast generation and load are changing and say, ‘No I’m just going to keep building the lines and reconductoring every line possible because I think my ratepayers will keep paying it.”

“What a utility gets rewarded on is deploying capital,” agreed Amirali. “Why build one line when you can build two?”

Rotenberg said his company has proposed a $30 million deployment of its technology for a western utility as an alternative to a $175 million reconductoring.

“Every regulator who’s heard about this project is saying, ‘How can I make sure my utility does it?’

“Eight of 10 [utility] CEOs … do understand [the value of cheaper non-transmission alternatives]. Only six out of 10 vice presidents of transmission understand that,” Rotenberg said. The transmission vice presidents’ view, he said, is that congestion is “not my cost.”

McCall said FERC should offer DLR compensation based on the difference in LMPs with and without constraints the devices relieve, similar to the way it designed the compensation scheme for demand response in Order 745.

Amirali said the commission also should reconsider its 2010 Western Grid Development ruling (EL10-19), which approved use of storage to defer a transmission upgrade but said such resources could not be used for any other purpose if they are receiving a rate of return. He said the ruling discouraged more widespread use of storage.

“You’re buying a Cadillac for one day a year,” he said. “It’s a wasted use of an extraordinarily dynamic asset.”

Bouchard © RTO Insider — Bouchard *© RTO Insider*

In a separate session, Philippe Bouchard, vice president of business development for Eos Energy Storage, praised Maine regulators for requiring utilities to evaluate untraditional transmission alternatives.

“It’s not a requirement that they go purchase energy storage or demand response or anything else. It’s just integrating that viewpoint into the methodology of looking at all available resources to meet their needs,” he said. “And there’s some really great opportunities, 15 or 20 miles of transmission lines that are stretching into the pockets of Maine that are ripe for [transmission and distribution] deferral.”

Jeffrey-Hein,-Xcel-Energy-web — Hein *© RTO Insider*

Jeffrey Hein, senior manager of regional transmission policy for Xcel Energy, said planning regions across the country have included non-transmission alternatives in their procedures. “This may now begin to introduce some competition, to …. pit technology against technology, old, new, what’s best to place where.”

Rotenberg said “one or two big wins” are all that’s required to change the mindset.

“Once we have one or two projects that everyone was certain were going to be a new line or rebuild and turn it into a non-wires alternative, everyone’s eyes will open up,” he said. “The hurdle [for building new lines or upgrades] is going to become much higher. The certainty … that that upgrade is required for a very long time is just going to keep going up and up.”

ERCOT Approaches 50% Wind Penetration Mark

ERCOT, wind — Roscoe Wind Farm at sunrise *Source: Wikipedia*

ERCOT continues to creep closer to the 50% mark for wind penetration, reaching 48.28% of load on March 23. The Texas grid operator said last week it generated 13,154 MW of wind energy at 1:10 a.m., when the overall load was 27,245 MW.

The ISO’s previous high for wind penetration was 45.14%, set on Feb. 18. Its wind peak remains 14,023 MW, also set Feb. 18.

ERCOT has 15,764 MW of installed wind capacity. Wind energy accounted for 18.4% of its system generation in 2015.

Inspection Finds Broken Bolts At Entergy’s Indian Point Unit 2

More than a quarter of the bolts securing plates directing water around uranium fuel rods at Entergy’s Indian Point 2 nuclear reactor were found to be either broken, deformed or missing, according to a report released on March 29.

The March 7 inspection by Entergy found that 227 of the 832 bolts were either damaged or missing, a failure rate of 27.2%. The company and the Nuclear Regulatory Commission may order a similar inspection of Indian Point 3 to see if there is a similar bolt issue.

The missing fasteners are a concern because similar bolt damage was identified as the cause of a partial meltdown of the Fermi reactor in 1966.

FERC Delays Approval Of 2 Pa. Pipelines

FERC has delayed the timetable to review two proposed Marcellus Shale natural gas pipelines, pushing the potential approval dates into early 2017.

The Atlantic Sunrise project in Pennsylvania, a Williams Partners project, was seeking authorization from FERC by the end of April. The FERC schedule expects the review to be completed in January 2017. That pipeline is planned to run south from Susquehanna County to link up with an existing Transco pipeline in Lancaster County.

The PennEast Pipeline, a $1.2 billion 114-mile line that is to run from Northeastern Pennsylvania into New Jersey, sought approval from FERC by August of this year. But the FERC schedule shows the review won’t be completed until March 2017. PennEast is a UGI project.

Bird Conservancy Group Targets 3 Wind Farms

The American Bird Conservancy says that three proposed wind projects near migration routes or important avian rookeries should not be built because they represent threats to endangered birds.

The conservancy said the turbines at two of the proposed wind farms, in North Dakota and in Kansas, are near migratory paths of the federally protected whooping crane. A proposed wind farm in northwest Missouri could threaten some of the migrating birds that use the Squaw Creek National Wildlife Refuge, including snow geese, bald eagles and trumpeter and tundra swans.

“There’s plenty of data to suggest that plenty of birds are being struck by the blades on these turbines,” a conservancy spokesman said. “Hundreds of thousands at a minimum.” The conservancy said wind farms in such areas should probably be prohibited.

Federal Weather Researchers See Record Ice Retreat in Arctic

NASA and the National Snow and Ice Data Center say the maximum ice buildup in the Arctic is coming in low this year. Ice growth for February was 1.16 million kilometers below average. And March’s reading, at 14.52 million square kilometers, was the lowest maximum extent on record.

This is the second straight winter that showed below-average maximum ice extents.

DOE Wants to Move 7 Tons Of Plutonium Cross Country

The Department of Energy is considering shipping nearly 7 tons of weapons-grade plutonium from the department’s Savannah River Site in South Carolina to the Waste Isolation Pilot Plant in Las Cruces, N.M.

The plan is going forward despite the fact that the New Mexico plant has been closed since February 2014 due to a fire and unrelated radiation release there. The plutonium was to be de-weaponized at the South Carolina site, but now the department plans to dilute it to a level where it can be shipped. The New Mexico facility is more than 2,000 feet below ground.

“The importance of keeping nuclear materials out of the hands of terrorists is clearer today than ever and is essential to protecting our nation and allies,” said the National Nuclear Security Administration.

FERC Staff: Reject Coaltrain ‘Rhetoric’

FERC staff told the commission Friday that a Pennsylvania-based power trading company’s response failed to dent their case that the company made riskless up-to-congestion transactions to collect line-loss payments. Staff asked the commission to uphold its findings and order the company to pay $42 million in penalties and unjust profits.

“Despite the rhetoric deployed throughout their lengthy submissions, the respondents do not credibly rebut the factual and legal conclusions in the staff report,” staff said in its response to Coaltrain Energy’s March 4 filing (IN16-4). The company’s answers to FERC’s Order to Show Cause contended it didn’t manipulate the market, that its trading strategy wasn’t deceptive and that it didn’t engage in wash trades or try to affect market prices.

As part of its response, staff included screenshots of one Coaltrain trader’s computer showing that he entered 137,800 MWh of “Over-Collected Losses” trades just three minutes after starting work on one day — evidence, staff said, that the trades were not based on “any meaningful research” but were intended to profit on the losses alone. Staff said Coaltrain also made misleading statements to PJM’s Independent Market Monitor in July and August 2010 in which it “falsely promised to stop making trades aimed at [collecting line-loss payments] after the IMM warned that trading to do so was illegitimate.”

FERC Orders MISO to Charge Uniform Interconnection Fees

By Amanda Durish Cook

MISO must charge equal fees to all generators entering its interconnection queue regardless of whether they are internal, external, new or existing resources, FERC ruled last week (EL15-99).

The commission also directed MISO to revise its Tariff to spell out procedures related to external resources entering the queue, a process currently described only in the RTO’s Business Practice Manuals. FERC agreed with a group of MISO generators who contended that the absence of an explicit Tariff provision created a lack of transparency around the nature of RTO service agreements with external resources.

“The commission requires that matters that significantly affect rates and services, are readily susceptible of specification and are not so generally understood be in the Tariff rather than Business Practice Manuals,” the order stated.

FERC considered the issue significant enough to open a separate Section 206 proceeding (EL16-12) to review MISO’s Tariff and require revisions outlining specific procedures and milestone payments for all interconnection customers.

The ruling stems from a complaint by a group of internal MISO generators who contested the RTO’s practice of exempting external generating resources from paying a significant fee levied on any new internal resources seeking to enter the final stage of the interconnection process.

At the outset of the definitive planning phase (DPP), any new MISO interconnection customers within the footprint must make an M2 milestone payment to fund system impact and interconnection facilities studies, as well as a later network upgrade facilities study, before preparing a construction schedule and cost analysis. Existing internal generators are exempted from the payments. MISO also waives the fee for both new and existing generators outside its footprint under the assumption that those resources have already established interconnection agreements within their own balancing areas.

The complainants contended that the differing payment requirements represent a competitive disadvantage for them because external generators face a “significantly lower entry fee than generation internal to MISO.” The generators further argued that the lack of monetary collateral tied to the DPP phase could lead external resources to submit speculative project requests or nonchalantly withdraw projects, forcing MISO to revise its study assumptions and thereby delay other projects in the queue. They asked FERC to consider two options: Either force MISO to require all new interconnection customers to pay the milestone payments or eliminate the payments altogether in the interest of fairness.

In its answer to the complaint, MISO said the request to treat existing external generation identically to new internal generation was unjust and unreasonable. The RTO pointed to the milestone payment exemption for existing generation, also noting that the payments are refundable upon finalizing a generator interconnection agreement. The RTO said it would resolve the payment dispute by charging “some form” of initial payment to external customers wanting to enter the queue.

In its ruling, FERC went a step beyond the complainants’ original request by requiring all interconnection customers — including existing internal generators — to post milestone payments.

“All interconnection customers, whether they are new or existing, or internal or external, are seeking interconnection service and will be entering the DPP,” the commission said. “The Tariff provisions should ensure that all interconnection customers, internal and external, and new and existing, are treated comparably.”

FERC gave MISO 60 days to update its Tariff with the changes related to the interconnection process. The changes must include a pro forma service agreement and initial payment details for external resources. A final order on the matter is expected by Nov. 30.

GridLiance Closes Deal for Tri-County Co-Op’s Tx Assets

By Tom Kleckner

Competitive transmission company GridLiance announced Monday it had closed its acquisition of about 410 miles of 69- and 115-kV transmission lines and related substation infrastructure from Tri-County Electric Cooperative (TCEC) in the Oklahoma Panhandle.

GridLiance CEO Ed Rahill called the transmission acquisition — GridLiance’s first —”an important milestone” for its business model to partner with cooperatives and other public power agencies.

GridLiance, which was formed in 2014, acquired Tri-County’s transmission assets and assumed full operational responsibility through its South Central MCN subsidiary, effective April 1. Under the transaction’s terms, GridLiance will represent the co-op and its members’ interest “in planning and development of new transmission projects within” SPP, the company said.

The company announced the deal in September. (See GridLiance Makes First Acquisitions.)

Rahill said his company would assume operations and maintenance responsibility for Tri-County’s assets, with the latter’s “boots on the ground” employees providing some O&M services.

“Over the long term, we can provide TCEC with a clear path to invest in SPP transmission projects that will reduce network congestion, increase service reliability and lower service costs,” Rahill said.

Tri-County CEO Jack Perkins said the move will allow the co-op to focus on its distribution system, with GridLiance upgrading the transmission assets. “Equally as important, we look forward to jointly investing with them in transmission projects that were previously inaccessible to us,” he said in a statement.

Headquartered in Hooker, Okla., the cooperative serves about 23,000 meters in the Oklahoma Panhandle, southwestern Kansas, the northern border of the Texas Panhandle and parts of Colorado and New Mexico.

GridLiance says its planning and development models are focused on providing more reliable transmission to public power customers, “hedging rising costs for regionally planned projects.” In addition to jointly planning, developing, owning and operating new transmission assets, GridLiance says it will work with entities such as Tri-County to identify “existing transmission infrastructure that can be more efficiently and cost-effectively upgraded and integrated into their RTO.”

GridLiance also announced Monday additions to its operations and compliance teams with the appointments of several regional-industry veterans to leadership positions: Kevin Hopper (late of Associated Electric Cooperative Inc.), president of the SPP Region; Neal Chapman (LS Power), vice president of engineering; and Jim Useldinger (Kansas City Power & Light), vice president of operations.

All three will be based in GridLiance’s Kansas City office and directly oversee the newly acquired TCEC transmission assets’ engineering and operations functions. The company said they will work with COO Noman Williams and Trent Carlson, regulatory and compliance vice president, to “build out its platform into other regions.”

GridLiance has also added several former SPP employees in recent months, including Brett Hooton, the RTO’s senior interregional coordinator, and Jody Holland, its manager of steady-state planning.

GridLiance is backed by Blackstone Energy Partners, an affiliate of New York private equity giant Blackstone Group.
