MISO: Data Still Lacking for Detailed Solar Capacity Credits

By Amanda Durish Cook

CARMEL, Ind. — MISO says the time is not yet ripe for creating a detailed solar capacity credit process, but it is leaning toward adopting a process similar to the one used to establish wind credits.

The RTO last week said it will continue its practice of using individual operational data to determine credits — with new solar units continuing to receive a 50% capacity credit — until more operational data are available to perform a full credit study. At that point, it will likely use its effective load-carrying capability (ELCC) measurement, a loss-of-load expectation-based study that examines the MISO system with and without certain resources, staff said.

Speaking during a Sept. 12 Resource Adequacy Subcommittee meeting, MISO Resource Adequacy Coordination Engineer Eric Rodriguez said the increasing number of proposed solar projects entering the interconnection queue portend a need for a study process. Solar projects comprise 35.7 GW of MISO’s 90-GW interconnection queue, but the RTO currently has just 314 MW of solar generation in commercial operation in front of the meter.

“Three hundred fourteen megawatts is not enough to perform the ELCC,” Rodriguez said.

Rodriguez pointed out that MISO first conducted an ELCC study for wind resources when MISO had between 5.6 and 8 GW of installed wind generation on its system. He said MISO would determine another accreditation process if a solar ELCC capacity credit study resulted in an unreasonably low credit.

He also told stakeholders that “other potential methods for crediting solar’s contribution to serving load will be investigated.”

“I hope we make good use of this buffer of time,” said Customized Energy Solutions’ David Sapper, suggesting that MISO’s wind capacity method might not work best for determining solar capacity credits, especially because the RTO’s recent renewable impact study shows that solar plays a role in managing the day’s traditional gross peak hour but leaves a more pronounced net load to be attended by other resource types. (See MISO Renewable Study Predicts Later Peak, Narrower LOLE Risk.)

MISO Manager of Probabilistic Resource Studies Ryan Westphal said the RASC will take up how solar is most effectively studied for capacity accreditation in 2019.

Other stakeholders urged MISO to act quickly on the issue, given that utilities file 15-year resource plans and would like to accurately gauge the value of their solar capacity.

Western RC Transition ‘Hot Topic’ at WECC Meeting

TEMPE, Ariz. — It’s been two months since Peak Reliability announced it will be winding down its operations at the end of 2019, but the issue won’t recede into the background any time soon, Western Electricity Coordinating Council members heard last week at the group’s annual meeting.

Just the opposite: Industry participants must now race the clock to ensure the Western Interconnection makes a smooth transition into a new era of balkanized reliability coordinator (RC) coverage.

“The hot topic of the day, and will be for the coming months … is the RC issue,” CEO Melanie Frye told the WECC board of directors Wednesday, the same day she revealed that CAISO is slated to provide RC service to about 72% of the West’s net energy load. (See CAISO RC Wins Most of the West.)

“Count me among those heartsick at what’s going on with Peak,” said Brian Theaker, director of market affairs at NRG Energy who also sits on WECC’s Member Advisory Committee (MAC). “I mean, we spent all this effort to put together the West-wide, interconnection-wide view, only to have it unravel like this, and I’m still just shaking my head from it.”

“I know that the Eastern Interconnection operates with multiple reliability coordinators … and the lights don’t go out,” said NERC Trustee Roy Thilly, who said NERC’s board has asked for a report on developments related to the RC issue at each of its meetings. “But the transition, I suspect, creates its own set of issues that we need to watch very carefully. We don’t want any gaps, no communication failures; and the structure has got to work in terms of the geography.”

Here’s more of what RTO Insider heard during the event about what Thilly jokingly referred to as “the little thing called the Western reliability coordinator set of issues.”

Transparency, Independency

Ortiz | WECC

David Ortiz, acting director of FERC’s Office of Electric Reliability, noted that the West consists of a network of load connected by a “relatively sparse” transmission network compared with the eastern U.S.

“The result is a system in which disturbances here in Arizona can be felt immediately in Washington,” Ortiz said, pointing out the region has deployed a collection of wide-area remedial actions schemes to support transmission operations. “Perhaps more than any region, maintaining reliability in the West does require a wide-area view.”

He said a successful RC transition will entail more than just the new RCs assuming Peak’s key functions. “This also requires that transmission operators and balancing authorities throughout the West work hand in hand with their reliability coordinators to maintain reliability.”

WECC members representing consumers expressed concerns that the new RC arrangement will be less transparent and provide them reduced input into reliability issues.

Maury Galbraith, executive director of the Western Interstate Energy Board (WIEB), previously told RTO Insider that WIEB has special concerns about how CAISO is proposing to govern its new RC. He noted that, unlike at Peak, CAISO’s member advisory committee would consist only of industry representatives. Also, CAISO does not plan to open RC meetings to the public, nor would meeting notes be made available to the public.

At the WECC meeting, Galbraith told WECC board members that WIEB’s Western Interconnection Regional Advisory Body (WIRAB) has submitted written comments to CAISO focusing on concerns about “transparent” and “independent” decision-making by the proposed RC, and a meaningful role for WIRAB to provide input and advice on RC activities.

Galbraith noted that WIRAB representatives had recently met with CAISO officials about their concerns, “and I’m hopeful that we’ll be able to resolve some of these governance issues with the folks at the Cal-ISO in the next several weeks.”

David Clark, a Utah Public Service Commissioner who also sits on both the WECC MAC and WIRAB, said state regulators have become accustomed to “an approach to RC coordination that has given us a lot of opportunity to participate, to observe, to gain comfort with the independence that’s been evident and the schemes that are used to remediate troubling — even threatening — conditions. In the future, we’re going to have a much different model, and we want to make sure that we don’t lose sight of some key principles as this new model evolves.”

Clark said those who have a statutory obligation to represent the interests of electricity customers “want some means of assuring ourselves that the daily, hourly, even minute-by-minute coordination is occurring effectively, independently of any improper influence. So we need transparency to be able to achieve that level of comfort.”

“We think WIRAB has an important role to play in this, and so we’re looking for WIRAB to be able to advise whoever is setting the policy for the reliability coordination function,” Clark added.

MAC representative Fred Heutte, of the Northwest Energy Coalition, said WECC end-use members seek “an appropriate role” for providing “broader input” into oversight of the region’s multiple RCs. “Not so much about the details, or about issues related to management of multiple RCs. But rather, what’s the appropriate role for the non-BA, non-TO stakeholders in the RC process.”

“That will be quite a bit different than what we’ve seen with Peak with member class representation and an independent board and a MAC and all that. The structures that will be in the new RCs will be quite different, but we think the same themes are involved,” Heutte said.

‘Clarity of Communication’

A guest panel on how reliability coordination works in the Eastern Interconnection — with its multiple RCs — pointed to the need for a different kind of transparency.

MISO seams management expert Ron Arness pointed out that his RTO coordinates its reliability activities with eight RCs.

“Transparency [into neighboring areas] is important,” Arness said, emphasizing the importance of “clarity of communications,” managing loop flows and developing congestion management tools. He also emphasized the importance of accurate internal and external models and performing drills to test coordination.

“It’s necessary to have a wide view,” Arness said.

Warren | WECC

Cameron Warren, manager of transmission operational planning at Entergy, noted that his utility joined MISO’s market and RC services in 2013 after functioning as its own RC since 1998. He offered a piece of advice to his Western counterparts facing the switch to a new RC.

“You’re moving to a company that’s not as familiar with your territory as you are,” Warren said. “Training is key.”

Lorissa Jones, of the Bonneville Power Administration, asked whether outage coordination policies are aligned throughout the East.

Yes, Arness answered. “It is important that outages are coordinated and communicated,” he said. “That clarity of communication is important here.”

WIRAB’s Galbraith asked how MISO provides transmission congestion relief to its neighbors that don’t participate in organized markets. Arness pointed to the RTO’s use of the transmission loading relief process.

“It does not take economics into account” in dispatch orders, instead functioning “purely on a reliability basis,” Arness explained.

“Is there some sort of higher-level forum where RCs from the Eastern Interconnection get together to collaborate and talk about interconnection-wide models or broader issues that affect more than one RTO or TOP?” Frye asked.

“I’m not aware of an official NERC organization that deals with the coordination of [energy management system] models, but people — like myself — we have a communication process,” Arness responded. “We’ve worked out a process where [MISO’s RC function knows] when MISO updates models, and we have to know when our neighbor updates their models, and we have to know how MISO’s going to get a copy of those models and know what those changes are. So that’s a structure and a process that’s built-in. It’s paramount.”

WECC board Chair Kris Hafner asked what the West should do — or avoid — as it transitions to multiple RCs.

Warren pointed to the importance of “having the RCs get together, communicate, lay out the operating agreements on how they’re going to manage any congestion that’s going to impact one utility or another. And ensuring that they go into it with a true wide-area view.”

Arness reiterated the importance of clear communication.

“Make sure clarity of communication is in place not only within the reliability coordination entity and all the various people that are working on reliability coordination, but also with neighbors. … Have the coordination agreements in place that spell out that that’s going to occur.”

7th Circuit Upholds Ill. ZEC Program

By Rich Heidorn Jr.

Illinois’ nuclear generation subsidies do not interfere with FERC-regulated wholesale power markets, the 7th U.S. Circuit Court of Appeals ruled Thursday in the latest judicial pronouncement on state-federal jurisdiction over the electric industry.

The 7th Circuit ruling in Electric Power Supply Association v. Anthony M. Starr upheld a July 2017 district court ruling and was consistent with an amicus brief by FERC that said the Illinois zero-emission credits program did not violate the Federal Power Act. Starr is director of the Illinois Power Agency. (See Analyst: FERC Asserts Role in Handling Nuke Subsidies.)

The court’s opinion cited the Supreme Court’s 2016 Hughes v. Talen ruling, in which the court rejected Maryland regulators’ attempt to subsidize a combined cycle plant, saying that the state’s contract for differences — which required the generator to bid into and clear the PJM capacity market — could distort prices. The court cautioned that its opinion should not “be read to foreclose [states] from encouraging production of new or clean generation through measures ‘untethered to a generator’s wholesale market participation.’”

“And that’s what Illinois has done,” the 7th Circuit said Thursday. “To receive a credit, a firm must generate power, but how it sells that power is up to it. It can sell the power in an interstate auction but need not do so. It may choose instead to sell power through bilateral contracts with users (such as industrial plants) or local distribution companies that transmit the power to residences.”

EPSA had contended that the ZEC program infringed on FERC’s jurisdiction by indirectly regulating interstate energy markets by using average auction prices as a component in a formula that affects the cost of the ZECs. But the court said the value of ZECs does not depend on the generators’ auction offers.

“Every successful bidder in an interstate auction receives the price of the highest bid that clears the market. The owner of a credit receives that market‐clearing price, with none of the adjustments that Maryland law required,” the court wrote. “The zero‐emissions credit system can influence the auction price only indirectly, by keeping active a generation facility that otherwise might close and by raising the costs that carbon‐releasing producers incur to do business. A larger supply of electricity means a lower market‐clearing price, holding demand constant. But because states retain authority over power generation, a state policy that affects price only by increasing the quantity of power available for sale is not preempted by federal law.”

The court also rejected claims that Illinois’ program violated the dormant Commerce Clause, saying “the cross subsidy among producers may injure investors in carbon-releasing plants, but only those plants in Illinois (for the state’s regulatory power stops at the border).”

The court noted FERC’s June ruling requiring PJM to change its minimum offer price rule to address capacity market price suppression from state subsidies for renewables and nuclear power. (See FERC Orders PJM Capacity Market Revamp.)

EPSA had contended that FERC’s ruling was proof that the Illinois statute must be pre-empted. “But that’s not what the commission said,” the court noted. “Instead of deeming state systems such as Illinois’ to be forbidden, the commission has taken them as givens and set out to make the best of the situation they produce.”

EPSA said it was reviewing the order and hadn’t decided whether to seek a Supreme Court review. A similar court challenge is pending in the 2nd Circuit over New York’s ZEC program. (See 2nd Circuit Hears New York ZEC Appeal.)

“Today’s decision confirms that state subsidy programs such as nuclear bailout ZECs can harm wholesale markets,” EPSA said in a statement. “FERC told the 7th Circuit the commission can mitigate these negative effects and today’s opinion relies on that representation. EPSA now expects FERC to act promptly in the pending PJM capacity market docket to prevent the acknowledged harms state ZEC programs inflict on federally-regulated wholesale power markets.”

Analysts at ClearView Energy Partners issued a research note Thursday predicting the 2nd Circuit will also uphold the New York ZECs. “If the ZEC’s opponents seek review at the U.S. Supreme Court (via a petition for a writ of certiorari), we think they face an uphill battle,” ClearView said.

The analysts acknowledged however, that the 2nd Circuit’s rejection of the New York ZEC program “could meaningfully improve the prospects for Supreme Court review” to resolve the split rulings.

WECC: Name to Remain the Same

By Robert Mullin

TEMPE, Ariz. — The Western Electricity Coordinating Council’s effort to clarify its mission will no longer include a name change, the group’s new chief said Wednesday.

Under previous CEO Jim Robb, WECC last year revived a proposal to change its name to “Reliability West” as part of a broader campaign to rebrand its image to reflect its refocus on its core reliability assurance mission after the 2014 bifurcation that divided WECC in its current form from what would become reliability coordinator Peak Reliability. (See WECC Finding New Direction in Old Mission.) The business case for the name change was set out in a November 2017 white paper.

The WECC Board of Directors tabled the name change in June after an advisory vote among the group’s members and also in light of WECC’s continued search for a replacement for Robb, who left his role to take over the top post at NERC. (See NERC Names WECC Chief to Top Post.)

“The rationale for the name change had some substantive content to it,” Chair Kris Hafner said during a quarterly meeting of the WECC board Sept. 12. “It was thought to basically bring to closure any lack of clarity posed by bifurcation and the respective roles of Peak and WECC and to avoid any role confusion.” That latter point became “a moot issue” after Peak’s July announcement that it would cease operations at the end of 2019, she noted. (See Peak Reliability to Wind Down Operations.)

“The hope Jim Robb had was to recast WECC in light of its new mission, to remove the ‘coordinating’ term from its name to avoid confusion with reliability coordinator — or planning coordinator,” Hafner said.

She added that brand clarity was another factor driving the change, given that other organizations share the WECC acronym, particularly the Wisconsin Energy Conservation Corp., which operates in four Western states in the electric power space.

Despite those issues, it turns out WECC’s name will remain unchanged.

Frye | WECC

“I appreciate the decision that the board made back in June, coming in as a new CEO to have an opportunity to be part of the conversation that I think is really thoughtful,” new CEO Melanie Frye told the board. “I think that it makes sense at this time to not proceed with a WECC change in name, but to do some things … to mitigate the risks and those things that we identified in the business case.”

Key among those things: changing the organization’s web address from a .biz to a .org to reflect its status as a non-profit.

“With that it would give us the opportunity to refresh the brand — the look and feel when someone visits our webpage, and know that they’re dealing with a reliability organization, not a conservation council,” Frye said, adding that WECC could refresh its logo and color palette in what that would “really identify and distinguish ourselves” from the other “WECC” entities. It would also build relationships with those organizations to handle situations when correspondence is misaddressed to them, she said.

Frye also suggested that WECC’s rebranding emphasize use of the shorthand version of its name, rather than the spelled-out version.

“I think the goal would be to not divert focus from our staff or from the industry in trying to address any change of name of the organization,” Frye said.

She told board members she would report back to them in December on any progress staff make in addressing the issues identified in the name change business case, and how they plan to proceed in 2019.

MISO to Focus on Customer, Employee Relations in 2019

By Amanda Durish Cook

MISO hopes to become more customer- and employee-focused in 2019, unveiling plans for a new feedback tool, a data gathering project and a new committee.

The RTO plans to create a Customer Experience Steering Committee next year that will examine customer perceptions of it and explore improvements it can make in interacting with them. It has yet to decide who will sit on the committee.

MISO also said it will create and introduce a “Voice of the Stakeholder” program to gather both customer and employee opinions. Senior Vice President and Chief Customer Officer Todd Hillman said MISO plans this year to begin “journey mapping” — collecting data by following customer requests or comments from submittal to the RTO’s response and eventual outcome. MISO has hired management consulting firm West Monroe Partners to assist on the project.

Hillman said MISO will create a “centralized platform” for capturing feedback from customers and employees to transform itself from a “service provider to a collaborative entity to a trusted RTO adviser and partner.” Speaking during a Sept. 11 conference call of the Corporate Governance and Strategic Planning Committee of the Board of Directors, Hillman said MISO will eventually examine and rank customer- and employee-experience improvements similarly to how it uses the Market Roadmap process to set priorities for market improvements.

MISO Director Mark Johnson asked if stakeholders will really offer ideas using the Voice of the Stakeholder program.

“They’re actually eager to provide the feedback, but the mediums we provide are limited,” Hillman responded. “We need to make this more routine.”

Hillman also said MISO’s current employee feedback tool was put in place in the early 2000s and is now “feeble.”

“There’s nothing more dangerous than asking employees what they think and not being able to act on it,” he added.

Meanwhile, MISO is circulating a survey through Sept. 26 to identify possible improvements on its current customer training process.

Unidentified: MISO to Use Prior Export Limit for Zone 5

By Amanda Durish Cook

CARMEL, Ind. — The Resource Adequacy Subcommittee has allowed MISO to use last year’s capacity export limit for Missouri’s Zone 5 after the RTO could not identify the limit.

MISO recently released zonal capacity import and export limits from this year’s loss-of-load-expectation study but said it could not find transmission constraints or a capacity export limit for Local Resource Zone 5. In its place, the RASC by consent allowed the Loss-of-Load-Expectation Working Group to use last year’s 2,122-MW export limit for the zone in the 2019/20 Planning Resource Auction.

MISO’s capacity export limits determine a local resource zone’s export capability on transmission for the PRA. When MISO cannot determine a transmission limit, it uses a generation-limited transfer study, which simulates further stressing of the transmission system after the RTO hypothetically runs out of generation to dispatch in the zone. The study is meant to discover whether a zone’s first transmission constraint would occur only after all the zone’s generation is dispatched at maximum levels.

In Missouri’s Zone 5 this year, no constraints were found even after the generation limited transfer study, said Laura Rauch, MISO director of resource adequacy coordination.

“We did run into an issue with Missouri capacity export limit,” Rauch told stakeholders attending a Sept. 12 RASC meeting.

Rauch also said MISO’s current process doesn’t provide for another analysis if it is unable to determine zonal transmission limits after an initial analysis and a generation-limited transfer study. “This is a situation that is not documented in our process,” she said. “We wanted to bring this to the RASC because this is a policy issue.” Rauch said the LOLEWG will begin working on a solution and codifying a new process.

Customized Energy Solutions’ David Sapper asked for more discussion on MISO’s options. He said because the RTO could find no constraint, the zone’s capability is hypothetically unlimited.

“I think it’s worth a round of feedback,” Sapper said.

“For the auction clearing, we do need to input some number, whether that’s 9,999” or another value, Rauch said.

RASC Chair Chris Plante said it was unlikely that imposing a limit as low as 2,000 MW or as high as 9,999 MW would affect auction clearing results.

Sapper pointed out that MISO using the previous year’s limit potentially opens the doors to using other previous capacity auction values. It could become that the “past is not prologue,” he said.

Consumers Energy’s Jeff Beattie asked the room if anyone thought the one-year adoption would violate MISO’s standard to value reliability first. Rauch said that standard does contain language allowing use of historic capacity limits when appropriate.

“Our view of Zone 5 is that there isn’t significant change from last year,” Rauch said.

New CONE values

MISO has also made its annual FERC filing to update its cost of new entry values for the 2019/20 planning year. The RTO’s CONE now ranges from a low of $81,640/MW-year ($223.67/MW-day) in Louisiana and East Texas’ Zone 9 to a high of $89,960/MW-year ($246.47/MW-day) in Missouri’s Zone 5.

“The estimates are down from a year ago, as they were last year, about $2,000 to $3,000 across the board,” MISO adviser Mike Robinson said.

CONE represents the estimated annualized capital cost of constructing a 237-MW nominal capacity combustion turbine plant in different locations in the footprint. MISO uses CONE as the maximum offer and maximum clearing price in its PRAs.

NYISO Business Issues Committee Briefs: Sept. 12, 2018

RENSSELAER, N.Y. — NYISO has asked FERC to reject a complaint by the Independent Power Producers of New York (IPPNY) seeking to bar the ISO from allowing PJM resources to sell installed capacity into Zone J using unforced capacity deliverability rights (UDR) facilities (EL18-189).

Presenting the monthly Broader Regional Markets report, Rana Mukerji, senior vice president for market structures, told the Business Issues Committee on Wednesday that IPPNY incorrectly assumes that transactions across Zone J merchant transmission facilities (MTF) would be subject to curtailment on the same basis as non-firm service within PJM. IPPNY also has not shown that transactions across the Zone J MTFs are no longer deliverable to the New York Control Area interface, Mukerji said.

“Whether the Zone J MTFs have firm TWRs [transmission withdrawal rights] or non-firm TWRs makes no practical difference for curtailment purposes,” NYISO said in its Aug. 20 response to IPPNY’s July complaint. “It was therefore reasonable for the NYISO to conclude that the TWR conversions do not impact the deliverability of transfers across the Zone J MTFs.”

PJM filed its response Sept. 5, saying that curtailments necessary for reliability would happen concurrently between the merchant facilities and PJM load on a pro rata basis. (See Perceiving Lack of Support, NJ Seeking Bigger Voice at PJM.)

Strengthening Unsecured Credit Scoring Model

The BIC endorsed changes to NYISO’s unsecured credit scoring model following its first review of the methodology since 2009.

John Jucha, senior credit analyst for corporate credit, said that to qualify for unsecured credit, a market participant must meet financial, credit rating and on-time payment history requirements.

The review found that the model was still performing “within an acceptable range” overall but that the calculation of revenue/market capitalization was not a reliable predictor of default for public companies, Jucha said. It also found that size variables were not represented in the model despite their “strong predictive power.”

Rating all market participants — including corporates, financial institutions and government entities — on the same scorecard may mask differences between them, the analysis found.

Under the new model, the 12.7% weighting for revenue/market cap will be replaced with a measure of total assets. The ISO also will consider using third-party credit ratings for non-corporate segments such as municipalities and financial institutions. It will also create additional rules for the qualitative assessment of market participants to reduce subjectivity under the current “open-ended assessment.” Additional changes were made to automate data entry and improve model transparency.

The BIC vote urges the Management Committee to recommend the changes to the Board of Directors.

Revisions to OATT Attachment L

The BIC voted to recommend the Management Committee approve revisions to Attachment L of NYISO’s Open Access Transmission Tariff updating terms regarding transmission congestion contracts (TCCs).

Gregory R. Williams, manager of TCC market operations, said the updates to Section 18.1.1 (Table 1A) of Attachment L followed an annual review. Among the changes were revising contract expiration dates from Dec. 31, 2017, to Dec. 31, 2027.

The ISO will seek approval of the revisions at the MC meeting Sept. 26.

Updating 2017 CARIS Database

Senior Planning Engineer Chen Yang reviewed changes NYISO is making in its Congestion Assessment and Resource Integration Studies (CARIS) Phase 1 database for Phase 2 studies extending through 2036. The Phase 1 base case covers the years 2017-2026.

Phase 2 of the Congestion Assessment and Resource Integration Studies (CARIS) database will aid in evaluating economic transmission projects through 2036. | NYISO

The Phase 2 base case, which will be used to evaluate regulated economic transmission projects and optional studies, incorporates retirements, additions and changes to in-service dates for more than a dozen generating facilities. The new model also reflects transmission capacity increases or other changes regarding six grid projects.

The ISO’s rules require it to review the changes with the BIC but do not require committee approval.

ISO to Begin Incorporating 100+kV Tx Facilities in Markets

Shaun Johnson, director of market mitigation and analysis, briefed stakeholders on a project to begin scheduling and pricing lower-voltage transmission in the day-ahead and real-time markets, beginning with four 100+kV facilities in November and 18 in December.

NYISO is the NERC transmission operator (TOP) for 230-kV and higher transmission in the state while the transmission owners are the TOPs for the lower-voltage system. The ISO helps the TOs manage constraints on the lower transmission lines through transaction curtailments, phase angle regulator adjustments, day-ahead reliability unit (DARU) commitments and other out-of-market actions, which can harm price formation efficiency and price transparency.

Johnson said the project will reduce out-of-market actions by allowing the market software to use more efficient solutions to thermal overloads when such solutions are available. It also will more accurately represent the cost in locational-based marginal prices to secure the system, he said.

NYISO’s Market Monitoring Unit, Potomac Economics, had recommended the move in each of its State of the Market reports since 2014, leading the ISO to publish a white paper on the topic in June 2017.

The MMU said that incentives to invest in resources on the 115-kV system in upstate New York are inadequate and that managing lower-voltage facilities through out-of-market actions has increased power supplier uplift payments and contributed to the need for cost-of-service contracts to keep older resources operating. At times, transfer limits on internal and external interfaces are reduced to manage 115-kV security.

LBMPs up 40% Year-on-Year

NYISO LBMPs averaged $42.56/MWh in August, up 7.5% from $39.58/MWh in July 2018 and nearly 40% higher than the same month a year ago, Mukerji said in his monthly operations report.

Year-to-date monthly energy prices averaged $46.37/MWh in August, a 30% increase from a year ago. August’s average sendout was 537 GWh/day, higher than 529 GWh/day in July and 477 GWh/day a year earlier.

Transco Z6 hub natural gas prices averaged $3/MMBtu, up about 10.5% from July and up 39.2% from a year earlier. Distillate prices climbed slightly compared to the previous month but were up 33.8% year-over-year. Jet Kerosene Gulf Coast and Ultra Low Sulfur No. 2 Diesel NY Harbor averaged $15.67/MMBtu and $15.36/MMBtu, respectively.

Total uplift costs and uplift per megawatt-hour came in higher than July, with the ISO’s 59 cents/MWh local reliability share in August up from 44 cents the previous month, while the statewide share dropped from -57 cents/MWh to -61 cents. Uplift, excluding the ISO’s cost of operations, was -2 cents/MWh, higher than -13 cents in July.

Thunderstorm alert (TSA) costs in New York City were 14 cents/MWh, down a third from 21 cents in July. TSAs are called when actual or anticipated severe weather conditions lead the ISO to reduce transmission limits on the UPNY-SENY interface, which often leads to severe congestion. Because a TSA may alter the capability of the transmission system in ways that are difficult to hedge in day-ahead markets, day-ahead prices reflect the probability-weighted expectation of infrequent high-priced events in the real-time market.

CAISO RC Wins Most of the West

By Robert Mullin and Tom Kleckner

TEMPE, Ariz. — CAISO is poised to take the lion’s share of the West in the competition for reliability coordinator (RC) customers, the Western Electricity Coordinating Council revealed Wednesday.

Speaking during the Regional Entity’s Wednesday board meeting, WECC CEO Melanie Frye said her organization has received tentative RC commitments from balancing authorities and transmission operators representing all but 2% of net energy load in the West.

The results: 72% of the region’s load will likely sign on with CAISO’s new RC, while 12% of load will go with SPP.

WECC and NERC requested that Western BAs and TOs declare their RCs by Sept. 4. The action became necessary when Peak Reliability, which has been providing the Western grid’s RC function following a major outage in 2011, announced in July that it will wind down its services by the end of 2019.

Frye also confirmed that BC Hydro is moving ahead with plans to set up an RC covering its own territory in British Columbia, Canada, representing about 7% of WECC load. Its neighbor to the east, the Alberta Electric System Operator (another 7% of load), will continue to provide for its own RC needs.

“Clearly, we need to follow up with the uncommitted to see where their intentions lie,” Frye said.

Among the uncommitted are Avista in northern Washington and Public Service Company of New Mexico (PNM), the state’s largest utility.

Frye said PNM was “leaning in one direction, but after hearing what their neighbors were doing, they are back into consideration.” The utility last month announced that it intends to join CAISO’s Western Energy Imbalance Market, while its neighboring BAs have recently signaled they are selecting SPP as their RC. (See PNM Seeks to Join Energy Imbalance Market.)

WECC declined to list the BAs’ RC selections, telling RTO Insider it would instead defer to each BA to make its own announcements.

But a map released by WECC at the meeting shows the SPP RC will still grab a big slice of the inland West, largely a product of the Western Area Power Administration’s decision to deepen its relationship with a market operator that already serves part of its sprawling transmission network. (See WAPA to Divide RC Services Between CAISO, SPP.)

CAISO’s RC will dominate the West Coast, Idaho, Montana, Nevada and Utah — areas heavily represented in the EIM. Frye offered a caveat regarding the map: “These are the draft nonbinding footprints that came in at our request. … Official commitments aren’t due into CAISO until Nov. 1.”

On Monday, SPP confirmed that 15 Western utilities have indicated they will use the RTO’s RC services:

  • Arizona Electric Power Cooperative
  • Black Hills Energy’s three electric utilities: Black Hills Power; Cheyenne Light, Fuel and Power; and Black Hills Colorado Electric
  • City of Farmington, N.M.
  • Colorado Springs Utilities
  • El Paso Electric
  • Intermountain Rural Electric Association
  • Platte River Power Authority
  • Public Service Company of Colorado (PSCo)
  • Tri-State Generation and Transmission Association
  • Tucson Electric Power
  • WAPA’s Desert Southwest, Rocky Mountain and Upper Great Plains-West regions.

The list did not include some utilities that WECC’s map indicates have also chosen SPP, including two small pockets in the Pacific Northwest which align with Avangrid’s recently inaugurated wind-heavy “Green Balancing Authority” on both sides of the Columbia River. Southern California’s Imperial Irrigation District, which has historically had a contentious relationship with CAISO, also appears to have selected SPP as its RC.

The RC elections will give SPP a presence in 21 states, adding Arizona, California, Colorado, Oregon, Utah, Washington and what appears to be a thin slice of Nevada to the 14 states where it currently has members: Arkansas, Iowa, Kansas, Louisiana, Minnesota, Missouri, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas and Wyoming.

PSCo had announced Sept. 11 that it had selected SPP as its RC provider. Ironically, the company in April all but put the kibosh on SPP’s planned integration of the Mountain West Transmission Group, announcing that it was withdrawing from the Rocky Mountain group and its efforts to join the RTO. (See Xcel Leaving Mountain West; SPP Integration at Risk.)

SPP COO Carl Monroe said he welcomed the news that PSCo has joined others in selecting the RTO as its RC. Those committing to SPP include all of the original Mountain West entities except Basin Electric Power Cooperative and two WAPA regions.

“We’ve worked hard over the last several months to demonstrate the quality and breadth of our service in terms of technical expertise, a customer-centric approach to doing business and the integrity of our people and processes,” Monroe said.

The RTO has said it remains committed to adding the rest of the Mountain West as members. However, that work has been overtaken by the Western RC initiatives. It said it will soon finalize plans for the governance and operation of its Western RC services, taking input from customers, neighboring RCs and regulatory stakeholders.

SPP plans to become certified as an RC in the second half of 2019 and to begin offering services in December 2019.

Frye said WECC will now begin “analytical work” related to transmission that crosses RC boundaries and look into whether there are “different types of studies we can do around frequency” issues. She said her organization also wants to convene a monthly call with BAs and TOs to consider a Western Interconnection-wide plan for transitioning to the new RC arrangements.

WECC will work with NERC to ensure the new RCs are certified and their members are properly registered.

“We’re also working with BC Hydro and [British Columbia] officials to see what kind of certification-like activity they will want to do in that province,” Frye said.

FERC, NERC to Probe January Outages in MISO South

By Rich Heidorn Jr. and Amanda Durish Cook

FERC and NERC announced Wednesday they are conducting a joint inquiry into the January cold snap that resulted in generation outages and loads that approached summertime highs in MISO South.

Uncharacteristically frigid weather prompted MISO to initiate a maximum generation alert for the South region for Jan. 17-18. With low temperatures averaging 13 degrees Fahrenheit on Jan. 17, MISO South’s peak load hit 32.1 GW, just short of the region’s all-time high of 32.7 GW set in August 2015.

MISO South reported about 17 GW of generation outages and derates that day, including nearly 10 GW in forced generation outages. Entergy Louisiana reported that about 32,000 homes and businesses lost power.

The FERC-NERC announcement cited “reports of multiple forced generation outages, voltage deviations and near overloads during peak operations.”

The inquiry, which FERC and NERC said is not an enforcement investigation, will seek to identify the causes and contributing factors to the event along with recommendations for improving operations in the future.

“This inquiry is timely as it will allow us to identify and share any potential lessons learned as we approach the coming winter season,” NERC CEO Jim Robb said. “It is also especially relevant that as the Western Interconnection reliability coordinator function fragments among multiple providers that we understand and underscore the importance of seamless RC-to-RC interactions.”

The Midwest Reliability Organization, ReliabilityFirst, SERC Reliability and utilities in the region will work with FERC and NERC staff on the inquiry.

The RTO declared conservative operations and a cold weather alert for MISO South — which spans Arkansas, Louisiana, portions of Mississippi and part of eastern Texas — beginning Jan. 15, when most of Louisiana was under a winter weather advisory.

Independent Market Monitor David Patton told stakeholders in March that if the RTO had not made emergency power purchases for South, regional supply would have dipped below load for several hours.

The Louisiana Public Service Commission called for an investigation of the episode in January. (See Louisiana Regulators Question MISO South Max Gen Event.)

MISO spokesman Mark Brown said the RTO doesn’t mind re-examining the event.

“While MISO and its neighbors worked together to maintain system reliability during the event, we recognize the opportunity to collaborate on changes that improve coordination during extreme events. We welcome the opportunity to advance the understanding within the industry and how MISO and its neighbors can continue to work together to support reliable and efficient operations,” Brown said in an emailed statement to RTO Insider.
