Mexican Market Poised to Withstand Political Change

By Tom Kleckner

HOUSTON — It’s a sign of the Mexican electricity market’s growing strength that at least some industry experts expect little change after the country’s presidential elections next year.

The country’s constitution limits presidents to single six-year terms. That means every six years, a new president and administration — usually from the Institutional Revolutionary Party (PRI) — is guaranteed to take power, leading to months of transitory uncertainty for the energy sector.

Derek Woodhouse, a partner with Woodhouse Lorente Ludlow, has been advising Mexico’s Energy Ministry (SENER) on implementing the wholesale market and drafting the geothermal energy law and regulations. He expects 2018 to be different.

“Regardless of who wins the election … they’re not going to be able to dramatically change what’s being done,” Woodhouse said during a Gulf Coast Power Association luncheon last week.

For one, Woodhouse said, market reform was written into Mexico’s constitution three years ago. “Second, because the market rules have been put in place, and can only be changed now by the market itself. It will be hard for them to mess up things,” he said.

“I think in many ways, that’s why it was assigned this way, so it can support political changes, and political changes will not affect dramatically what is going on.”

Continuity or Inertia?

Woodhouse would know. In the late 1990s, he was part of a team drafting the country’s initial market reform proposal. When Vicente Fox ended 71 years of PRI rule with his surprise victory in the 2000 election, it put a halt to the market reforms.

“When Fox won the election, nothing happened — not for 12 months,” Woodhouse said. “That’s a political risk of having a new party [in control], because then you cannot have the same teams running the show.”

Woodhouse said the difference now is the nearly three dozen market rules that have been — or soon will be — put in place since new industry laws and regulations were passed in 2014. They govern everything from financial transmission rights auctions to market registration and outage scheduling. A code of conduct and operating guidelines and procedures are among those rules yet to be developed.

Still, further changes will only be expedited if the PRI manages to replace incumbent President Enrique Pena Nieto with another one of its own, Woodhouse said.

“Then you have continuation. At the end of the administration, people … probably know they’re not going to be here, so why take any risk? Why start something you’re not going to end? That triggers a year of nobody doing anything,” Woodhouse said.

Continuity does reign within the Energy Regulatory Commission (CRE), an independent body from the state-owned Comision Federal de Electricidad (CFE) that has long controlled Mexico’s electricity business. CFE is currently being restructured into separate generation, transmission and distribution businesses.

Woodhouse said inertia during the transition between administrations can still be a problem, however.

“You need to wait for the new panel to take over those positions, to learn what to do, and start doing it,” he said. “You have 12 to 18 months that nothing happens. It’s sad because it shouldn’t be like that. They have the tools to make changes, and they’re simply not using them.”

Growing Private Sector Role

SENER is implementing the wholesale market in phases through 2018. It consists of short-term markets (day-ahead, hour-ahead, real-time and ancillary services), medium-term auctions (three-year energy and capacity contracts), long-term auctions, FTR auctions, a capacity balancing market and the 20-year clean energy certiﬁcates market for instruments equivalent to 1 MWh of energy from clean sources.

The market’s third long-term auction last week set a new low for average prices at $20.57/MWh, bettering the $33.47/MWh average set in September 2016, according to preliminary results. Mexico will add 2.56 GW of capacity from 16 new projects, with a total investment of $2.36 billion by international players from Canada, China, France, Italy, Japan and Spain.

Among the winners was Consorcio Engie Eolica, a consortium involved in one of the Tres Mesas wind farm phases in Tamaulipas. (See Energy Wildcatter Hopes to Make His Mark in Emerging Mexican Market.)

Eventually, SENER will hand over the keys to CRE. (See Mexico’s Power Market Continues to Gain Strength.)

Woodhouse says there is still a steep learning curve for those used to the old way of doing things. No longer can CFE sell energy to the end user.

“We’re devising something that will allow them to look good politically but still incentivizes the private sector to negotiate contracts,” said Woodhouse, who has focused his career on private-sector participation in infrastructure projects traditionally reserved for the public sector.

“Hiring consultants would lengthen the process by 12 months, so we came with the idea of allowing them, from the top, to sit down and negotiate,” he said. “They’re not used to doing that. That was perceived as something corrupt. We are giving them that option because now, legally, they can do it. But they’re still very nervous. ‘Yeah, but how is it going to look if I sit down and discuss a contract with someone?’”

Woodhouse said the market is just awakening, with many players “just learning how to play the game.” Only five companies are listed as qualified suppliers, and a number of their contracts are in the 1- to 3-MW range.

“They’re testing the waters to see how their software runs,” Woodhouse explained.

FERC Rejects NERC Bid to Reduce Transparency

By Rich Heidorn Jr.

FERC last week rejected NERC’s request to eliminate public posting of self-reported compliance exceptions and to expand compliance exceptions to include some moderate-risk violations.

“In most situations, information on NERC’s resolution of compliance and enforcement matters should be transparent and publicly available,” the commission said. The rejections came in an order in which the commission accepted NERC’s annual report on its Compliance Monitoring and Enforcement Program (CMEP) (RR15-2-005).

In February 2015, the commission allowed NERC to move to a risk-based approach to compliance monitoring and enforcement, which allowed low-risk violations of reliability rules to be recorded and mitigated without formal enforcement actions. It also allowed registered entities that passed a NERC review of their internal controls to self-log and mitigate minimal-risk violations, subject to periodic, rather than individual, reviews by the Regional Entity. (See New NERC Enforcement Methods Allow Self-Logging Minor Risk Issues.)

Incentive Lacking?

NERC said the commission “unintentionally removed an incentive for registered entities to participate in the program” when it required public logging, contending that it had reduced interest in the program.

The Edison Electric Institute, the ISO/RTO Council (IRC) and MISO transmission owners were among those supporting NERC’s proposal to eliminate public posting. The IRC noted that only 59 of more than 1,200 registered entities participate in self-logging, saying that the incentives to participate were inadequate.

The American Public Power Association, Electricity Consumers Resource Council, National Rural Electric Cooperative Association and Transmission Access Policy Study Group opposed the elimination of public posting in a joint filing, saying the transparency was needed to educate the industry and preserve the credibility of NERC’s enforcement program. They said that because compliance exceptions are a significant percentage of noncompliance, the public disclosures allow registered entities to understand compliance requirements. They also said the public posting could help identify unnecessary or redundant reliability requirements.

The commission said it agreed with the commenters who supported continued public disclosure. “The value of maintaining the transparency of self-logged noncompliance continues to outweigh the asserted benefit that might accrue from increasing the incentive to participate in the program,” FERC said, citing the “minimal” burden of public posting and the benefits it provides in “educating industry and ensuring consistency across NERC’s and the Regional Entities’ compliance and enforcement programs.”

Find, Fix and Track Program

FERC also rejected NERC’s proposal to expand the compliance exceptions program to include moderate-risk noncompliance, although all commenters supported NERC’s request.

Moderate-risk violations that have been corrected are currently subject to the Find, Fix and Track (FFT) program, which allows NERC to process them through informational filings instead of the formal Notice of Penalty procedure.

“We are not persuaded that the claimed efficiency gains in processing certain moderate-risk violations as compliance exceptions, rather than as FFTs, are sufficient to outweigh our concerns with treating many moderate-risk noncompliances through a nonenforcement track,” FERC said. “While this approach may be appropriate for minimal risk violations, NERC has not adequately justified this limited approach for moderate-risk violations.”

The commission also raised questions about the FFT program, saying its staff had identified a compliance exception involving falsification of battery testing records by a registered entity’s employee that was disposed of via the FFT process. “The commission does not consider it appropriate to process instances of noncompliance involving falsification of records as compliance exceptions or FFTs,” it said. “Rather, such circumstances warrant a full Notice of Penalty.”

NOPR on Training, Coordination of Protection Systems

In a separate Notice of Proposed Rulemaking, the commission proposed reliability standards PRC-027-1 (Coordination of Protection Systems for Performance During Faults) to ensure protection systems used to detect and isolate faults operate in the intended sequence.

The NOPR also proposed the approval of reliability standard PER-006-1 (Specific Training for Personnel) to ensure that personnel involved in real-time operations are adequately trained (RM16-22).

Generators’ Rehearing Bid on ISO-NE Scarcity Rules Denied

By Rich Heidorn Jr.

FERC last week rejected a request to expand its time frame for relief in a dispute over ISO-NE rules punishing resource withholding (EL16-120-001).

In January 2017, FERC agreed with the New England Power Generators Association (NEPGA) that ISO-NE Scarcity Rules Unfair to Generators, FERC Says.)

FERC set a refund effective date of Sept. 30, 2016, the date NEPGA filed its complaint.

NEPGA filed a rehearing request asking the commission to apply the revised PER — and any resulting refunds to capacity suppliers — to an Aug. 11, 2016, scarcity event.

FERC on Thursday rejected the request, saying it would impose “an unforeseen and significant increase in costs” to load.

“Such application is inconsistent with the commission’s notice requirements under the [Federal Power Act],” FERC said. “We recognize that there is a lag between when the event occurs and when the billing to reflect the PER adjustment takes place; that lag in billing, however, does not satisfy the notice requirements under the FPA.”

The January order said the amount of the PER increase would be determined in an evidentiary proceeding if stakeholders were unable to reach a settlement.

On Aug. 31, Settlement Judge H. Peter Young certified an uncontested settlement requiring ISO-NE to increase the daily PER strike price for each hour “by the amounts that actual five-minute reserve shadow prices exceed the pre-December 2014 reserve constraint penalty factors (RCPF) values for 30-minute operating reserves and 10-minute non-spinning reserves ($500/MWh and $850/MWh, respectively).”

The revised strike price will replace the strike price value in hourly PER calculations for Sept. 30, 2016, through May 31, 2018. The settlement has not been approved by the commission.

NEPGA President Dan Dolan and ISO-NE officials could not be reached for comment.

SPP to Modify Service Agreements with KMEA, Sunflower

FERC last week accepted network transmission service agreements between SPP and Kansas Municipal Energy Agency (KMEA) and Sunflower Electric Power, pending modifications to address the inconsistent treatment of a generation resource (ER17-889).

The commission directed SPP to make a compliance filing within 30 days to resolve a modeling discrepancy in the power-flow analysis, which failed to account for a 9-MW gas turbine (Garden City 2) at KMEA’s Jameson Energy Center in Garden City, Kan.

SPP agreed to file revisions to KMEA’s service agreement to reflect the additional network resource, with an effective date of March 1, 2017, and to remove a reference to the unit that imposes revenue crediting requirements.

The RTO filed with FERC in January service agreements between it and KMEA as a network customer, and between it and KMEA and Sunflower as a network customer and host transmission owner, respectively. Commission staff tentatively accepted the agreements in March while FERC lacked a quorum.

Sunflower and its Mid-Kansas Electric owner, which also includes five co-ops and a not-for-profit electric company, intervened to point out the initial service agreement with KMEA excluded Garden City 2 but required the unit to pay revenue credits as a network resource. They requested FERC require SPP to remove the unit from the revenue credit payment or add Garden City 2 as a network resource.

SPP acknowledged its mistake and said it performed an additional analysis using updated model information, reposting the results in an aggregate transmission service study in February. It confirmed network service for KMEA used Garden City 2 as a designated network resource, effective March 1.

FERC OKs Cost Allocation of PJM Transmission Projects

By Rory D. Sweeney

FERC last week approved cost responsibility assignments for 39 baseline upgrades recently added to PJM’s Regional Transmission Expansion Plan (ER17-2362).

The allocations were filed on Aug. 25. Thirty-five projects will be allocated to the transmission zone in which they are located, including five projects of less than $5 million each. Two projects will address Form 715 local planning criteria, and 28 involve circuit breakers and associated equipment. The remaining four projects are “lower voltage facilities” that are allocated based on the solution-based distribution factor (DFAX) method.

Old Dominion Electric Cooperative challenged two of the DFAX allocations, saying it was unable to replicate PJM’s analysis. It asked the commission to direct PJM to provide the detailed information “for the sake of transparency” and to determine whether the upgrades are appropriately allocated entirely to the American Electric Power zone. ODEC questioned PJM’s 100% allocation of another project to the American Transmission Systems Inc. zone, arguing that the results of the DFAX analysis produce a 1.32% allocation to ATSI.

FERC accepted PJM’s defense of its allocations. The RTO said because only ATSI had a DFAX percentage greater than 1% for project b2898 — reconductoring the Beaver-Black River 138-kV line — that zone was assigned the entire cost of the $20 million project.

PJM said it used “an appropriate substitute proxy” for the baseline projects, reactive power upgrades that can’t be addressed by DFAX analysis, which measures over transmission lines or transformers. PJM developed an “interface comprised of the lines and transformers that surround the entire AEP system,” a localization method PJM often uses “because the majority of reactive power upgrades are intended to provide local voltage support.”

ODEC has also asked the D.C. Circuit Court of Appeals to overturn FERC’s policy of allocating all costs from Form 715 projects to the zone of the transmission owner whose criteria triggered the upgrades. ODEC said the cost allocation for the two Form 715 projects should be subject to the outcome of its challenge.

AEP Base ROE Complaints Ordered to Settlement

By Rory D. Sweeney and Tom Kleckner

FERC said last week it didn’t have enough information to decide on complaints that American Electric Power affiliates are raking in unreasonable returns for transmission projects in PJM and SPP, instead establishing hearing and settlement judge procedures.

In PJM, American Municipal Power, Blue Ridge Power Agency, Craig-Botetourt Electric Cooperative, Indiana Michigan Municipal Distributors Association, Indiana Municipal Power Agency, Old Dominion Electric Cooperative and Wabash Valley Power Association filed complaints that AEP’s current 10.99% base return on equity is excessive. They requested a base ROE no higher than 8.32% and asked for refunds with interest. The change would save them $142 million annually in transmission costs, they said (EL17-13).

The complainants hired a consultant to develop a peer-group analysis that included 25 utilities similar to AEP. That analysis found a “zone of reasonableness” of between 5.62 and 9.46% and that the median of the values, 8.32%, was more appropriate than the midpoint.

Multiple state agencies intervened to support the complaint, including the Indiana Office of Utility Consumer Counsel, the Office of the Ohio Consumers’ Counsel, the Virginia Division of Consumer Counsel, the Virginia State Corporation Commission and the Indiana Utility Regulatory Commission.

An ad hoc group of large commercial and industrial end-use customers also commissioned an analysis, which found an appropriate zone between 5.64 and 9.44%, recommending a base ROE of 8.22%.

AEP responded with its own analysis that found an appropriate zone between 6.41 and 11.71% and that using the midpoint of the upper half of the range, rather than the median, was consistent with FERC rulings.

FERC found the complaint compelling enough to explore further and called AEP’s argument that the current rate falls within the reasonable zone “unpersuasive.”

“The commission has repeatedly rejected the assertion that every ROE within the zone of reasonableness must be treated as an equally just and reasonable ROE,” the order said, setting a refund effective date of Oct. 27, 2016.

SPP Complaint

FERC also established identical procedures for East Texas Electric Cooperative (ETEC) in its complaint against AEP subsidiaries Public Service Company of Oklahoma (PSO), Southwestern Electric Power Co. (SWEPCO), AEP Oklahoma Transmission and AEP Southwestern Transmission, setting a refund effective date of June 5, 2017 (EL17-76).

The cooperative in June asked the commission to reduce the companies’ 10.7% base ROE to 8.36% within SPP’s AEP West pricing zone. PSO and SWEPCO’s current base ROE derives from a transmission formula rate settlement agreement filed Feb. 23, 2009.

ETEC contends the base ROE is no longer just and reasonable and that its ratepayers are currently overcompensating the AEP West companies by $36.6 million annually.

The companies countered that the 9.53% upper end of an ETEC consultant’s zone of reasonableness falls more than 100 and 80 basis points below the ROE that FERC previously approved for ISO-NE and MISO, respectively.

The commission said it was “unpersuaded” by the argument, saying “the relief [ETEC] seeks here is an ROE that falls well below the current ROE, based on different facts, risks, proxy companies and time periods” than those in previous decisions.

Downstate NY to Pay 90% of AC Tx Projects

By Rich Heidorn Jr.

FERC on Thursday approved NYISO Tariff revisions ordering downstate residents to pay 90% of the cost of AC transmission projects stemming from public policy needs (ER17-1310-001).

The projects, which include the estimated $1 billion Edic-Pleasant Valley 345-kV line and the $246 million Oakdale-Fraser 345-kV line, are intended to relieve downstate congestion by upgrading the AC transmission systems north and west of New York City.

The cost allocation was proposed by the ISO at the direction of the New York Public Service Commission, which said 75% of the costs should be allocated solely to the downstate load zones that will benefit from the congestion relief, with the remaining 25% allocated regionally based on load-share ratio. “According to the New York commission, this method will allocate approximately 90% of the transmission project’s cost to ratepayers in the downstate region, and about 10% to upstate ratepayers,” FERC said.

FERC rejected a protest by four State Assembly members, who said the regional allocation of 25% was too low to account for “some of the financial and societal benefits to ratepayers statewide.”

The commission said the proposed allocation satisfies Order 1000’s requirement that it be “roughly commensurate” with the benefits that the load zones receive, citing a study published by the PSC that found 89.5% of the costs should be allocated to the downstate load zones.

However, the commission added that the ISO’s filing “does not prevent the selected transmission developer from submitting its own proposed cost allocation method for the AC transmission upgrades. The Tariff specifically provides that the selected transmission developer may also file, for the commission’s approval, an alternate cost allocation method or request that NYISO use the default cost allocation method (i.e., load-share ratio).”

ROE Settlement

In a related order, the commission approved a settlement with New York Transco — affiliates of the New York Transmission Owners, Consolidated Edison of New York, National Grid, Iberdrola USA and Central Hudson Gas & Electric — to decide questions regarding their potential compensation for the projects (ER15-572).

The commission had set the matter for hearing in April 2015. (See Divided FERC Trims ROE on NY Tx Projects, Orders Hearing.)

The settlement, which will apply only if NY Transco is selected as the developer, includes a 9.65% base return on equity and a 100-basis-point adder that will apply up to the cost cap, which was defined as the capital cost bid plus an 18% contingency and an inflation factor of 2% per year.

The commission said the settlement, which was unopposed and endorsed by both the New York PSC and FERC staff, “appears to be fair and reasonable and in the public interest.”

Cost Containment

FERC did not rule on state regulators’ proposed cost-containment mechanism, under which ratepayers would be responsible for 80% of any overruns above the estimated cost of the project and retain 80% of any savings.

The commission said it couldn’t rule because the ISO had provided only a description of the risk-sharing proposal without Tariff language. “As such, [the mechanism] is not properly before us,” the commission said. “NYISO states that it plans to file Tariff sheets for the 80/20 risk-sharing mechanism after concluding its stakeholder process.

“In regard to implementing the 80/20 risk-sharing mechanism, because the New York commission recognizes that [FERC’s] policy on cost recovery allows transmission developers to recover costs that are prudently incurred, it proposes to limit the selected transmission developer’s ability to recover costs associated with cost overruns by reducing the allowed return on equity for the transmission project,” FERC added.

Selection Process

NYISO received 16 proposed projects from six developers in response to a February 2016 solicitation for solutions to address the transmission congestion. In a January order, the PSC told the ISO it “should proceed to a full evaluation and selection, as appropriate, of the more efficient or cost-effective transmission solution to meet the” public policy transmission need.

NYISO spokesman Michael Jamison said the ISO hopes to release draft results of its analysis by the end of the first quarter of 2018. “Subsequent to that, the NYISO will select the more efficient or cost-effective project. At that time the NYISO will work out a developer agreement with the chosen party, and that party can initiate actions with the state under the Article 7 transmission siting process.”

ISO-NE Planning Advisory Committee Briefs: Nov. 16, 2017

WESTBOROUGH, MA — Boston leads large, northeastern cities in economic growth, outpacing both New York and Philadelphia in payroll employment, Moody’s Analytics economist Ed Friedman told the ISO-NE Planning Advisory Committee on Thursday.

According to figures compiled by Moody’s from the U.S. Bureau of Labor Statistics, Boston posted better than 2% growth in payroll employment for the three months ending September 2017, compared to approximately 1.7% growth in Philadelphia and less than 1.5% in New York City.

“The job growth in Boston is quite strong and significantly above the U.S. pace, which is around the 1.5% mark,” Friedman said.

Friedman characterized New England job creation in the aggregate as “slow but steady” at 1% per year and said that housing price gains in the region are mostly keeping up with the national average of just more than 6% for the year ending in August 2017. Of the six states in the region, only New Hampshire and Massachusetts exceeded the national average; housing prices in Massachusetts, where health care remains a strong economic driver, increased by almost 7%.

Both Connecticut and Vermont lost population in the past two years. Nonetheless, Moody’s expects economic growth in the region to continue in 2018 at about 1.3%, with “some deceleration consistent with the demographic challenge” of lost population, Friedman said.

RTO Readies Maine Resource Integration Study

ISO-NE on Thursday presented a draft of its Maine Resource Integration Study to the PAC, its first transmission planning study to employ queue clustering under Tariff revisions approved by FERC Approves ISO-NE Queue Clustering.)

The Northern and Western Maine grid was built to serve the small loads in the area and lacks capacity for the more than 5,800 MW of proposed new resources, mostly wind, that have filed interconnection requests. The 5,800 includes duplicate requests.

The resource integration report will provide the basis for system impact and facilities studies, which will identify the upgrades required for resources that proceed to interconnection and their cost allocations, said Al McBride, ISO-NE director of transmission strategy and services.

Maine 2027 Needs Assessment Moves Forward

The RTO’s draft Maine 2027 Needs Assessment study is ready for stakeholder comment, Jinlin Zhang, ISO-NE lead engineer for transmission planning, told the PAC.

Comments and notifications by proponents of state-sponsored requests for generation should be submitted to pacmatters@iso-ne.com by Dec. 3.

The study identifies reliability-based needs in Maine for the year 2027, considering future load distribution, resource changes in New England based on Forward Capacity Auction 11 results, and 2017 solar and energy efficiency forecasts.

Planners look at reliability over a range of generation patterns and transfer levels, how the study coordinates with the New Hampshire Needs Assessment, and all applicable NERC, Northeast Power Coordinating Council (NPCC) and RTO transmission planning reliability standards.

The completed draft report and intermediate study files will be presented to the PAC in the first quarter of 2018.

RTO Begins Zone Planning for FCA 13

ISO-NE has begun assessing transmission transfer capability, generation retirements and new resources to set capacity zone boundaries ahead of FCA 13 for 2022/23.

The process includes evaluation of the zones as determined for FCA 12, McBride said.

Each year, the RTO must identify weaknesses and limiting facilities that could impact the transmission system’s ability to reliably transfer energy in the planning horizon. Any new boundaries require a filing with FERC, McBride said.

The process of certifying transmission projects begins in October and is coordinated with that month’s Regional System Plan (RSP) Project List update to ensure consistency. Transmission owners are required to provide models and contingency definitions. The RTO will determine certifications by January; the list of certified projects will be presented at the January Reliability Committee meeting.

Transmission upgrades identified for Southeast Massachusetts/Rhode Island (SEMA/RI) are not expected to change the boundaries of the area. Planners do not expect such upgrades to be fully certified for FCA 13, nor will transfer limits be updated in time for that auction in 2019.

Any major resource retirements received for FCA 13 will be considered in the zone formation process, McBride said. No major retirements were received for FCA 12.

Time-Sensitive Tx Needs Determination

Pradip Vijayan, ISO-NE senior transmission planning engineer, made a presentation on how the RTO identifies time-sensitive transmission upgrades — those required within three years and thus not subject to the competitive solicitation process.

RTO officials consider when an upgrade will be required after identifying improvements in a needs assessment.

Needs identified from a short-circuit analysis are considered time sensitive unless they are driven by future projects that have an in-service date beyond three years of the completion of the needs assessment.

Steady-state needs observed at off-peak load levels are considered time sensitive. Those seen at peak load levels may or may not be time-sensitive.

The RTO will add a document detailing the process to its Transmission Planning Technical Guide, Vijayan said.

Tx Planning Assumptions Update

ISO-NE is continuing to update the probabilistic methodology and minimum load level used in its transmission planning assumptions, Director of Transmission Planning Brent Oberlin said.

The generator dispatches used in base cases in his report showed the potential for a significant number of generators to be simultaneously unavailable, especially in the Eastern Connecticut (ECT) area. ISO-NE said in October that it would revise the scope of its 2027 needs assessments for ECT, Southwest Connecticut and New Hampshire over stakeholder questions about dispatch modeling assumptions. (See “Tx Planners Rethink 2027 Needs Assessment,” ISO-NE Planning Advisory Committee Briefs: Oct. 18, 2017.)

The ECT data showed that up to 488 MW of generation could be unavailable at peak load. The largest generator in the ECT study area is Montville 6 (413 MW), with 13 other generators totaling only 253 MW, which shows that the presence of a single large generator in an area with a low number of smaller generators can skew the results, Oberlin said.

The new methodology solves the issue by recalculating the upper limit of generation outages using the probabilistic method by excluding the large generator for dispatches in which it is assumed in service. By applying this method to ECT, the maximum amount of generation unavailable is limited to 115 MW in cases with Montville 6 in service.

The new methodology lowers the minimum load level to 8,000 MW from 8,500 MW, correcting an error on the handling of Maine mill loads (currently 320 MW) in the evaluations, Oberlin said.

Cauley Resigns; NERC Launches Search for Replacement

By Rich Heidorn Jr.

NERC announced Monday that its Board of Trustees had accepted the resignation of CEO Gerry Cauley, effective immediately, following his arrest for domestic abuse.

The organization said General Counsel Charles Berardesco will continue to serve as acting CEO while the board seeks a search firm to recruit a replacement.

“NERC has a talented staff and an experienced leadership team that is well-equipped to continue the forward momentum on key initiatives,” Board Chair Roy Thilly said in a statement. “I am confident we will continue to meet milestones and expectations going forward. NERC remains committed to maintaining the reliability and resilience of the bulk power system.”

A NERC spokeswoman declined to comment when asked whether Cauley would receive any severance payment. “Any personnel action is confidential,” she said.

Also pictured are Board Chair Roy Thilly (to Cauley’s right), and board members Jan Schori (left) and Frederick W. Gorbet (foreground). | *NERC*

NERC had placed Cauley on a leave of absence after his arrest for battery, a misdemeanor, for allegedly assaulting his estranged wife in the early morning of Nov. 10. The police report documenting his arrest states that his wife, Jean Cauley, sustained bruises and scratches and was experiencing a great deal of pain in her back.

The report quoted Jean as saying he attacked her after she discovered him having cybersex with a “young female employee of his.” (See Cauley Arrest Tied to Relationship with NERC Subordinate.)

Jean, a former probation officer and child abuse investigator for the state of Florida, posted a comment about the incident on her LinkedIn page Sunday: “Who knew that when I married a CEO — and me with a background in law-enforcement — [I] would be a victim of a violent crime by her husband to the point of a back being broken,” she wrote. “It shows that no one is exempt from domestic violence and that we should all support each other as women.”

Cauley, 64, had served as NERC CEO since January 2010, and was often the face of the reliability agency in hearings before FERC and Congress. By Monday afternoon, however, his biography and photo had been removed from the web page listing the organization’s management.

No End Seen to State-Federal Tensions

By Rich Heidorn Jr.

BALTIMORE — State-federal tension over electricity policy is likely to continue even after current debates over nuclear and coal subsidies end, speakers told the National Association of Regulatory Utility Commissioners’ Annual Meeting last week.

In fact, said former FERC Commissioner Tony Clark, “things are probably going to get more tense and more difficult before they get easier.”

Clark, an adviser for Wilkinson Barker Knauer who left the commission in September 2016, said there will be pressure for additional state interventions because of the impact of renewables on energy market prices. “Increasingly we see even … relatively new gas units that are stressed in certain markets. Any resource that has higher fixed costs and variable operating costs is going to be challenged in any sort of market where you have price takers with zero variable cost units that are at the margins.”

In addition, he said, FERC may begin asserting its authority on power “from the edge of the grid,” such as rooftop solar.

“Up until this point, FERC has kind of walled that off and basically … been able to ignore what happens since that’s been on the state jurisdiction side of things,” he said.

“It’s hard to argue that all of these exponentially growing resources at the edge of the grid — in which a sale is by default a sale for resale — [is not] federally jurisdictional activity. To this point it hasn’t been that big a deal. It’s becoming a very big deal.”

Ari Peskoe, of Harvard Law School’s Environmental Policy Initiative, said legal challenges to Illinois’ and New York’s zero-emission credits for nuclear plants “expose a question that courts have not addressed in the 20 years of restructuring: May a state provide an incentive for energy production without intruding on FERC’s exclusive jurisdiction over energy sales? Perhaps the state authority over generating facilities means just that — the facilities themselves, and not the energy that they produce,” he said.

“There’s little doubt that states can enact all sorts of command-and-control regulations over pollution from those facilities. States can issue emission limits or simply prohibit the burning of fossil fuels within their borders. But what about financial regulation of pollution and avoided pollution? And what about state regulation of utility portfolios? ls there some limit on state power that limits states just to those traditional integrated resource plan tools?”

Peskoe filed an amicus brief defending the Illinois ZECs. “Expanding the scope of FERC’s exclusive jurisdiction to swallow up ZECs, [renewable energy credits] and other emissions taxes and allowances will disrupt how the industry and how regulators have understood jurisdictional limits,” he said.

If the courts accept opponents’ reading of the Federal Power Act, “we can expect lawsuits about a range of state programs,” he said, adding, “Now concerns about market distortions from ZECs seem pretty quaint in light of [the U.S. Department of Energy’s] recent Notice of Proposed Rulemaking.”

Peskoe said that if ZECs survive the current legal challenges, “existing state policy would be relatively safe from these pre-emption challenges going forward. Then the action turns back to FERC and what FERC is going to do.”

He said FERC’s May 1-2 technical conference on integrating wholesale markets and state public policies “was a really positive step … so I hope that the DOE NOPR and whatever happens after it doesn’t sort of suck the air out of the room and that conversation keeps happening.” (See RTO Markets at Crossroads, Hobbled FERC Ponders Options.)

Clark said FERC must determine when state actions reach a “tipping point” for its markets. “Whether you think the ZEC is the tipping point or the DOE NOPR is the tipping point, there is a tipping point that FERC has to be concerned about in terms of its maintenance of the integrity of the wholesale market,” he said.

“What happens when say … coal-friendly states decide, ‘It looks like RECs and ZECs are the way to go. What we need now is a coal energy credit,’” Clark asked.

“We are called the Environmental Policy Initiative, so we don’t love the idea of coal credits,” Peskoe responded. “I’m somewhat comforted by the fact that about 30 states actually enacted RPS and, so far, zero states have enacted coal standards.”

Former Commissioner Marc Spitzer (2006–2011) was more succinct: “If they’re zero-emission coal, go for it!” he joked.

Spitzer, a partner with Steptoe and Johnson, also supported ZECs, saying states are “entitled to deference and forbearance.”
