Michigan Dam Ordered Shut over Safety Breaches

By Amanda Durish Cook

FERC last week ordered the shutdown of a Michigan hydroelectric project over longtime safety violations — the most significant of which relate to inadequate spillway capacity.

The commission will revoke the license for Boyce Hydro’s 4.8-MW Edenville Dam in northern Michigan on March 1 following its Feb. 15 cease generation order and denial of the company’s request for rehearing on the issue (10808-058).

FERC dismissed Boyce’s arguments that the commission didn’t consider corrective measures the dam had already taken; that it doesn’t have authority to order a dam to shut down; and that the cease generation order was arbitrary and capricious. FERC has been threatening to close Edenville since late last spring.

The commission last month gave Boyce until March 1 to correct violations, some of which that have persisted since 2004, including:

Failing to increase spillway capacity to address the increased likelihood of more frequent flooding;
Performing unauthorized dam repairs and excavation;
Neglecting to file a public safety plan or follow its own water monitoring plan; and
Failing to acquire all property rights and to construct required recreation facilities near the dam.

FERC has repeatedly told Boyce to construct two auxiliary spillways to reduce the risk of flooding, “a grave danger to the public,” the commission wrote.

“Boyce Hydro’s license includes terms and conditions concerning dam safety, property rights, water quality, public recreation and safety, and other areas of public concern,” the commission said. “Boyce Hydro has a long history of noncompliance with those terms and conditions … [and] failed to comply … except for the obligations to acquire and document certain property rights (although the lack of designs for the new and revised spillways makes it difficult to determine if it has acquired all necessary property rights).”

The commission in January granted Boyce a temporary stay of shutdown until the beginning of March so the company can use the dam’s powerhouse to pass flows to alleviate ice formation on spillway gates during winter. (See Michigan Dam Faces Shutdown over Longtime Safety Concerns.)

FERC said Edenville’s current spillway can only currently handle 50% of a probable maximum flood.

The commission ordered Boyce last year to file plans to construct spillways and provide public access and recreational facilities by late 2017, but the filings never materialized, it said. Although Boyce had hired an engineering firm to design a new spillway and promised to create an escrow account for 50% of its gross revenues to fund construction, FERC found those plans insufficient, saying that it would take the company two years to save enough money to fund spillway construction.

“Given that the public has already been at risk for more than 13 years due to the licensee’s refusal to remediate the project spillways, we cannot accept a proposal that will perpetuate the problem even longer,” FERC said.

The commission expressed disbelief that Boyce’s lengthy history of noncooperation would change now.

“After weighing the relevant factors, commission staff determined that the violations required prompt action and that the licensee’s persistent pattern of noncompliance provided strong evidence that it would not make serious efforts to come into compliance absent an order disrupting its operation,” the commission wrote.

FERC said it didn’t take the economic impacts of a shutdown lightly but said the move is “a situation of Boyce Hydro’s own making.”

Boyce can seek a rehearing of the order before a FERC administrative law judge within 30 days.

Trade Group Seeks Expanded DR Measures in MISO

By Amanda Durish Cook

A distributed energy resource trade group is calling on MISO to open its markets to customer-owned demand response and urging state regulators and utilities to develop programs that reimburse small DR providers.

The Advanced Energy Management Alliance (AEMA) last week issued a white paper containing model Tariff language intended to extend access to MISO’s wholesale markets to customer-owned demand-side resources.

The white paper suggests that states in the RTO’s footprint adopt DR programs like those in New York and the portion of Indiana in PJM.

MISO AEMA Demand Response Hydropower — | *Advanced Energy Management Alliance*

“While not new to the Midwest, the growth and development of demand response in the region has largely stagnated,” AEMA wrote. “To create shared value for utilities and consumers, states should take near-term action to create robust demand response programs where demand response is lacking and evolve demand response program design in territories that have had the same tariffs for over a decade.”

Like in the PJM area of Indiana, AEMA suggests having utility-qualified DR providers register their customers with a utility, which would then enroll the customers in MISO’s DR program. The utility would receive capacity credit for customers they enroll, and DR providers would get either an average price from MISO’s annual capacity auction or 35% of the net cost of new entry. AEMA said the approach would be “an effective means for stimulating cost-effective DR while working within existing state and MISO market constructs.”

As an alternative, AEMA said MISO could adopt New York-style programs that concentrate on reducing transmission and distribution costs and stay independent of wholesale capacity programs.

The organization also said that if states agree, MISO could devise Tariff rules for peak load management, distribution-level services and, eventually, additional wholesale market programs.

AEMA also suggested that Midwestern states allow bilateral contracting between utilities and DR providers. Under this scenario, the utility and the provider contract for a specific number of megawatts for enrollment, a price per megawatt and program design — including the terms of dispatch.

“AEMA is eager to collaborate with MISO-based utilities, regulators and system operators in this endeavor. Our goal is not to overturn existing bans that prohibit demand response providers from directly enrolling customers in wholesale market programs, but instead to develop new creative approaches to exploiting the full potential of demand response,” the group said.

It said new DR resources are less expensive than running aging generation.

“Energy leaders in the Midwest should not let excess capacity stop them from pursuing all cost-effective demand response,” the organization said.

AEMA Executive Director Katherine Hamilton said the white paper is a “roadmap” for state regulators and utilities.

“We hope that this white paper is used as intended — to inform and offer options for regulators and utilities seeking to partner with third-party providers and consumers. AEMA members seek to grow our businesses while giving consumers additional choices and providing cost-effective, environmentally sustainable services to the electric grid,” Hamilton said.

Several utilities in MISO states have interruptible DR programs, but AEMA said those programs need to evolve.

MISO had 10.7 GW of wholesale DR capacity in 2016, 8.9% of its annual load peak. The RTO’s DR is mostly derived from interruptible load and behind-the-meter generation under state-regulated and utility-run programs and accredited as load-modifying resources or emergency demand resources.

ITC Subsidiary Gets OK to Buy Michigan Tx Assets

FERC last week authorized an ITC Holdings subsidiary to purchase transmission assets from a small southwestern Michigan city.

The ruling authorizes Michigan Electric Transmission Co. to spend $201,206 to buy transmission assets at the Black River Substation from the City of Holland Board of Public Works (EC18-21). The assets include surge arrestors, relay panels, circuit breakers, backup relays and disconnect switches that Michigan Electric plans to use in its transmission operations.

The commission said the acquisition was consistent with the public interest and won’t hinder competition in the area. Michigan Electric has also pledged to hold all transmission customers harmless from any transaction costs for five years.

“The proposed transaction does not involve any change in ownership or control of any generating facilities. Accordingly, the proposed transaction will not have any impact on concentration in any relevant market,” FERC said. The commission also said that prior experience suggests that sales involving only the transfer of transmission facilities are unlikely to result in uncompetitive activity.

Ameren Rate Incentive Rejected by FERC

FERC last week declined to grant Ameren additional transmission incentive rates for portions of the company’s 500-mile Grand Rivers project in Illinois and Missouri.

Ameren sought a 100-basis-point incentive adder for the return on equity for the Illinois Rivers and Mark Twain components of the project, which is intended to create a continuous 345-kV path from Iowa to Indiana. The company also requested authorization to assign the incentive to any affiliate that undertakes the development, construction or ownership of those portions of the project.

FERC Grand River Project — Grand River Project | *Ameren*

The commission said the segments were already too far developed to be considered risky enough for incentive rate treatment (ER18-463).

“We find that, due to the late stage of … development, including the substantial completion of the Illinois Rivers component, Ameren Transmission has failed to demonstrate that the remaining risks and challenges associated with the components warrant the requested ROE incentive,” the commission sad. “A project that is further along in construction and thus closer to completion typically faces fewer remaining risks and challenges, and we find that is true here.”

FERC agreed with the contention by the Organization of MISO States and the Missouri Public Service Commission that Ameren had already spent 77% of its cost estimate on the two lines when it asked for the rate incentive in mid-December, when permitting risks were minimal and already covered by a previously approved abandonment incentive. Ameren had argued that the two lines face “unprecedented” risks that are not covered by its other rate incentives.

The commission has previously granted several incentives for the Grand Rivers Project, including 100% construction-work-in-progress recovery, abandoned-plant recovery, a hypothetical capital structure and the authority to assign incentives to affiliated entities.

FERC Finalizes Frequency Response Requirement

By Rich Heidorn Jr.

New generators seeking interconnections must be equipped to provide primary frequency response, FERC ruled Thursday (Order 842, RM16-6).

The commission said the requirement that generators have governors or other equipment to respond automatically to frequency disturbances must be included in the pro forma generator interconnection agreements (GIAs) for both large (20 MW+) and small generators.

The rules will apply to new generation and existing generators that seek a new interconnection agreement because of “material modifications” to their facilities. The commission declined to order existing generators to retrofit their facilities to provide the service, saying it would be “prohibitively expensive” for some.

The final rule makes only small changes from the commission’s November 2016 Notice of Proposed Rulemaking, which cited concerns by NERC and others that frequency response has declined with the loss of traditional synchronous generation and the increase in asynchronous renewables. (See FERC: Renewables Must Provide Frequency Response.)

The commission cited a 2010 NERC survey that found only 30% of generators in the Eastern Interconnection provided primary frequency response and that only 10% provided “sustained” response. The commission said the existing pro forma large GIA — which required primary frequency response from only synchronous generating facilities — does not reflect technological advances allowing nonsynchronous generation to provide the service.

The commission set operating requirements of a maximum droop setting of 5% and a deadband setting of ±0.036 Hz.

“We find that the establishment of minimum uniform operating requirements for all newly interconnecting generating facilities is preferable to the fragmented and inconsistent primary frequency response settings currently in place throughout the Eastern and Western Interconnections,” FERC said. ERCOT already has minimum frequency response requirements, FERC noted.

FERC agreed with recommendations by the Edison Electric Institute and the Western Interconnection Regional Advisory Body that it modify the rule to explicitly prohibit interconnection customers from blocking their governors’ ability to respond to frequency deviations.

“One of the commission’s concerns with the current lack of clear, uniform primary frequency response requirements is NERC’s finding indicating that a number of generator owners/operators have implemented operating settings that have effectively removed the availability of their generating facilities from providing timely and sustained primary frequency response (e.g., wide deadband settings, uncoordinated plant-level controls). The reforms adopted in this final rule, to be applied uniformly to new generating facilities, are intended to eliminate these practices.”

The commission disagreed with the National Rural Electric Cooperative Association’s (NRECA) contention that the rule is premature, saying “adopting these requirements now is more prudent than waiting until the lack of primary frequency response undermines grid reliability, a point acknowledged by NERC’s Essential Reliability Services Task Force.”

Headroom, Compensation

The commission rejected EEI’s proposal that generators be required to maintain headroom — allowing them to increase output in response to low frequency — and receive compensation for doing so. “If future conditions necessitate a headroom requirement, we will then consider any appropriate compensation,” it said.

FERC also said it would consider on a case-by-case basis requests from transmission providers seeking to impose a headroom requirement “in a particular factual circumstance” that includes a compensation mechanism.

The commission said compensation is not necessary because “the cost of installing, maintaining and operating a governor or equivalent controls is minimal.” FERC estimated the cost of adding governors to new wind and solar generators would average $3,300/MW, about 0.2% of total capital costs for wind and solar.

FERC also rejected requests that it order compensation for traditional generators that provide inertial response. “No commenter asserts that inertial response trends on the Eastern and Western Interconnections are approaching levels that could threaten reliability. In addition, because inertial response is provided automatically by the rotating mass of synchronous machines as system frequency deviates and is not controllable, synchronous generating facilities do not incur additional incremental costs to provide inertial response,” the commission said.

Exceptions and Accommodations

The commission exempted or offered accommodations to some classes of resources:

Combined heat and power (CHP) generators that are sized to serve onsite load and have no ability to export power to the grid will be exempt from the operating requirements but must install a governor “in the event that there is an increased need in the future for primary frequency response capability.”
Energy storage will only be required to provide frequency response within specified operating ranges representing minimum and maximum states of charge. The commission said the accommodation would prevent the premature degradation of storage resources.
Distributed energy resources will be required to provide frequency response only when they are allowed to ride through disturbances, the commission said in response to Xcel Energy’s concern that dynamic frequency response at the distribution level can interfere with anti-islanding protections. The rule does “not supersede a generating facility’s ride-through settings or require an interconnection customer to override anti-islanding protection or any protective relaying that has been set to disconnect the generating facility during certain abnormal system conditions,” the commission said.
Nuclear generators are exempt from the rule because their licenses with the Nuclear Regulatory Commission often restrict providing frequency response.

No Exemption for Wind, Small Generators

Wind generation must comply with the requirement, the commission said, rejecting an exemption request by Sunflower Electric Power and Mid-Kansas Electric.

“Unlike certain CHP or nuclear generating facilities, the record does not indicate that there is an economic, technical or regulatory basis for a generic exemption for newly interconnecting wind generating facilities,” FERC said. “In particular, we are persuaded by [the American Wind Energy Association’s] assertion that the proposed primary frequency response capability requirements can be met at low cost for new wind projects, and that newly interconnecting wind facilities should not have difficulty complying.”

Small generators also will not be exempt. The commission said the rule will not result in “unduly burdensome” costs or create a barrier to entry, noting that PJM has not seen a decrease in small generator interconnections since it required nonsynchronous generation to install enhanced inverters with frequency response capability. “We are persuaded by commenter assertions that that small generating facilities are making up a growing percentage of the generation resource mix, and that as the market penetration of small generating facilities increases, there will be a growing need for primary frequency response from these generating facilities,” FERC said.

The commission rejected NRECA’s request that individual balancing authorities be permitted to seek waivers from the rule but agreed that “unique circumstances or needs of some individual regions or areas may warrant different operating requirements.” FERC said it would consider variations based on Regional Entity reliability requirements; variations that are “consistent with or superior to” the final rule; and “independent entity variations” filed by RTOs and ISOs.

The revised GIAs are due 70 days after publication of the rule in the Federal Register.

ISO-NE Study Finds Wind ‘Spillage,’ Price Separation

By Rich Heidorn Jr.

ISO-NE could see substantial “spillage” of renewable energy and large price separations because of transmission constraints under scenarios considered in the RTO’s 2017 Economic Study, officials told the Planning Advisory Committee on Wednesday.

The study was requested by the Conservation Law Foundation to evaluate scenarios for meeting Massachusetts and Connecticut climate laws and the Regional Greenhouse Gas Initiative’s emission caps.

The study was based on the “Renewables Plus” scenario from the 2016 Economic Study, which modeled the year 2030 — the only scenario in the 2016 study to meet the RGGI cap. (See Study: New Resources Could ‘Crowd Out’ Old in ISO-NE.)

ISO-NE RPS Wind Power Regional Transmission Overlay Study — | *ISO-NE*

Under Renewables Plus, the generation fleet met existing renewable portfolio standards, and new renewable or clean energy resources were added above existing RPS requirements.

The new study looked at three additional scenarios:

“EE + Offshore”: Added more energy efficiency and offshore wind while reducing imports from Canada by 1,000 MW.
“Onshore Less EE/PV”: A variation on the business-as-usual base case from the 2016 report, with onshore wind boosted to 7,000 MW (nameplate capacity) from 4,800 MW in the reference case.
“Wind Less Nuc”: Assumes the Millstone nuclear plant retires by 2030, five years ahead of its license expiration, with the gap filled by renewable/clean energy resources.

The study found all three scenarios met projected demand, even with transmission constraints based on the “as-planned” system’s internal and external transfer limits.

If transmission constraints are not relieved, the RTO would see “spillage” of wind power north of the Surowiec-South interface, leading to lower prices in Northern Maine than southern New England. For example, under the constrained scenarios, 7 to 18% of renewables would be spilled, with 22 to 89% of the spillage north of Surowiec-South.

In the constrained Wind Less Nuc scenario, average LMPs would range from $13.78/MWh in the Bangor Hydro Electric subarea in northeastern Maine, to $38.71/MWh in the NH subarea (which includes most of New Hampshire, eastern Vermont and southwestern Maine) and $37.18/MWh in Boston.

Electric production by natural gas plants fluctuates with assumptions regarding plant retirements and price-taking offers ($0/MWh) by renewable resources. EE + Offshore has the least gas-fired energy, while Wind Less Nuc has the most gas production, especially when the transmission system is constrained.

EE + Offshore had the lowest total production costs, coming in 28% below the Renewables Plus reference case assuming transmission constraints. Onshore Less EE/PV had the highest costs, 77% above the constrained reference case.

Only one scenario, EE + Offshore, is as good as the Renewables Plus scenario in meeting the RGGI 2030 emission targets.

CLF staff attorney David Ismay said the two emission-reduction targets, which were also used in the 2016 study, were intended to “bracket” the goals RGGI might embrace in its latest program review. RGGI’s emissions cap declines by 2.5% annually through 2020. The group announced in August that it would seek an additional 30% reduction in emissions from 2020 levels.

“We expressly worked … to design all three scenarios to meet [RGGI] emissions targets,” Ismay said.

“We’re starting to get a better picture of what the grid needs to look like in order to meet our climate laws and emission regulations that are already on the books,” he explained in an interview later. “We really need a grid that’s different from what we have now. I think that will give legislators, regulators and the ISO information on the kind of mix we need to comply with these laws. … It’s really helpful to see the impact of adding 1,000 MW of EE or 1,000 MW of wind.”

Stakeholders have until April 2 to submit requests for additional economic studies. Requests should be emailed to PACMatters@ISO-NE.com.

MISO Evaluating Economic Modeling for Tx Projects

By Amanda Durish Cook

MISO is embarking on a review of its entire economic planning process in an effort to more accurately capture the benefits of cost-shared transmission projects.

“This is not about MISO saying the existing process is broken or flawed,” Matt Ellis, of the RTO’s Economic Planning Users Group, told stakeholders at a Feb. 13 Planning Subcommittee meeting.

Ellis said MISO is looking forward to FERC-level discussion on best practices for planning and that it will continue to talk about economic models throughout 2018.

MISO especially wants to take a fresh look at:

The economic impacts of transmission outages;
Voltage and local reliability resource commitments, especially in MISO South load pockets where performance has lagged;
MISO’s emergency energy supply and how it’s being valued in economic models when it defers transmission and generation investment or prevents scarcity pricing and loss-of-load events;
Accounting for likely import and export flows in adjusted production costs; and
Forecasted renewable resource ownership and which members will actually purchase the energy and benefit when considering renewable portfolio standards.

Further, the RTO plans to hold stakeholder discussions through June on other possible measurable benefits that could be valued in the modeling of market efficiency projects. It could consider such benefits as the deferral of reliability projects; savings that could arise from opening up it contract flow path with SPP that bridges MISO South and Midwest; reduced transmission energy losses; reduced ancillary services costs; and deferral of capacity expansion stemming from increased capacity import/export limits.

MISO economic modeling market efficiency projects — | *MISO*

Ellis asked for member companies’ engineers to come forward with other ideas about overlooked benefits of market efficiency projects that could be assigned a monetary value.

Minnesota Public Utilities Commission staff member Hwikwon Ham cautioned that renewable standards are set by state legislatures and can be changed. Ellis responded that MISO is looking for that kind of information and other input.

He also said timely changes to MISO’s modeling could affect how it judges potential projects in its annual Market Congestion Planning Study for the 2018 Transmission Expansion Plan.

“We are fully aware that having a process review in parallel with having the process is not an ideal situation. It introduces a lot of ‘what-ifs,’” Ellis said. He promised that MISO would test any projects affected by an economic model change using both the old and new models and that it could delay implementing the new aspects of economic modeling.

MISO announced its plan the same week it proposed to lower the voltage threshold for market efficiency projects to 230 kV, and two weeks after FERC ordered a technical conference on how PJM, MISO and SPP coordinate generator interconnection studies after developer EDF Renewable Energy complained that the RTOs’ modeling standards violate the FERC requirement for transparent open access interconnection service.

Con Edison Q4 Earnings Up 144%

Consolidated Edison’s fourth-quarter net income increased 144% to $505 million ($1.63/share) from $207 million ($0.68/share) in 2016, the company said last week.

Total revenue for the quarter increased 9.38% to $2.961 billion.

The company reported 2017 net income of $1.525 billion ($4.97/share), compared with $1.245 million ($4.15/ share) in 2016. Total revenue was down slightly in 2017 but remained above $12 billion.

PJM PSEG Con Edison earnings Q4 — Con Edison Composition of Regulatory Rate Base as of Dec. 31, 2017 | *ConEd*

Con Ed said its adjusted earnings for 2017 excluded the remeasurement of deferred tax assets and liabilities upon enactment of the federal Tax Cuts and Jobs Act, the effects of the gain on the sale of a solar electric production project, and the net mark-to-market of Con Edison’s clean energy businesses.

The company’s earnings presentation showed the new law reduced the net deferred tax liabilities for its Con Ed of New York, Orange and Rockland Utilities and Rockland Electric subsidiaries by more than $5 billion collectively.

Con Ed plans to meet its 2018 capital requirements through internally generated funds and the issuance of securities. The company’s plans include issuing between $1.3 billion and $1.8 billion of long-term debt at its utilities and additional debt secured by its renewable electric production projects.

The company also plans to issue up to $450 million of common equity in addition to equity under its dividend reinvestment, employee stock purchase and long-term incentive plans. The plans do not reflect the provision to utility customers of any tax law benefits that may be required by the New York Public Service Commission or the New Jersey Board of Public Utilities.

NYISO Business Issues Committee Briefs: Feb. 14, 2018

RENSSELAER, N.Y. — NYISO power prices surged to an average of $99.55/MWh in January, up 89% from December and 148% from the same month a year ago, Rana Mukerji, senior vice president for market structures, told the Business Issues Committee on Wednesday.

The ISO’s year-to-date monthly energy prices averaged $101.54/MWh in January, an increase of 142% from a year earlier. Average sendout was 463 GWh/day, compared with 444 GWh/day in December and 431 GWh/day a year ago.

New York natural gas prices jumped 136% for the month, averaging $17.94/MMBtu at the Transco Z6 hub. Prices were up 369% from a year ago. Gas prices peaked at $140.06/MMBtu on Jan. 4, near the end of a two-week cold spell.

FERC on Jan. 12 granted a waiver request enabling the ISO to consider incremental energy and minimum generation offers that exceed $1,000/MWh if the generator is able to demonstrate such costs. The waiver covers Jan. 4 to Feb. 28. (See FERC Grants NYISO ‘Cold Snap’ Offer Cap Waiver.)

Distillate prices gained 28.2% year over year, with Jet Kerosene Gulf Coast averaging $14.47/MMBtu. Ultra Low Sulfur No. 2 Diesel NY Harbor averaged $14.83/MMBtu, up from $13.91/MMBtu in December.

The ISO’s local reliability share was 59 cents/MWh, up from 9 cents/MWh the previous month, while the statewide share dropped 74 cents from the previous month to -$1.52/MWh. Total uplift costs were lower than in December.

Evaluation of Energy Market Offer Cap

Reviewing the Broader Regional Markets report, Mukerji highlighted NYISO’s ongoing effort to resolve differences between regional offer caps that may interfere with economic- and reliability-driven interchange scheduling.

FERC this month accepted NYISO’s Order 831 compliance filing, which requires the grid operator to cap incremental energy offers at the higher of $1,000/MWh or a resource’s verified cost-based offer, which in turn are capped at $2,000/MWh when calculating locational-based marginal prices.

Mukerji also noted that FERC last month accepted the ISO’s motion to terminate its obligation to submit annual informational filings on its implementation of interface pricing and congestion management and market-to-market coordination initiatives with its neighboring RTOs/ISOs.

The report also said the ISO has analyzed real-time commitment (RTC) and real-time dispatch (RTD) convergence and last month presented the Market Issues Working Group with recommendations to continue to aid the convergence this year. The ISO aims to improve modeling consistency between RTC and RTD and assess improvements to look-ahead evaluations to facilitate more efficient scheduling and price convergence.

NYISO also is working to clarify the minimum deliverability requirements for external capacity from PJM into the New York Installed Capacity (ICAP) market, Mukerji said. At the Jan. 17 BIC meeting, the ISO received approval for ICAP Manual revisions regarding the documentation requirements for capacity imports across the PJM AC ties, which will become effective May 1. (See “BIC Recommends ICAP Manual Revisions,” NYISO Business Issues Committee Briefs: Jan. 17, 2018.)

Day-Ahead Market Congestion Settlements

The BIC on Wednesday recommended that NYISO’s Management Committee approve revisions to Attachment N of the Tariff that provide a methodology to allocate day-ahead market congestion rent shortfalls and surpluses resulting from changes in transmission facility availability to the responsible transmission owner.

Operations Analysis and Services Supervisor Tolu Dina explained how the methodology uses a de minimis threshold to determine circumstances when allocations to responsible TOs are not calculated.

The threshold applies to day-ahead constraint residuals (shortfalls and surpluses resulting from changes in transmission facility availability) that are less than $5,000, provided the sum of all such residuals below the threshold is not greater than $250,000 or 5% of the sum of all residuals for the month. Attachment N currently requires the ISO to conduct certain informational calculations once a year to help in assessing whether the de minimis threshold level presents any concerns.

External Capacity Rights

The BIC approved revisions to the ICAP Manual to better define the amount of capacity that can be imported into New York from neighboring control areas for the 2018/2019 capability year.

Josh Boles, the ISO’s manager for ICAP operations, said the New York State Reliability Council regulates the amount of emergency assistance from neighboring RTOs and “we’re only allowing imports up to a level where we would violate the one-day-in-10 criteria.”

Alternative Methods for Determining LCRs

The BIC recommended the Management Committee approve revisions to the Market Administration and Control Area Services Tariff to establish an alternative method for calculating locational minimum installed capacity requirements.

NYISO natural gas prices business issues committee — | *NYISO*

Zachary Stines, associate market design specialist, presented NYISO’s market design for determining locational capacity requirements (LCRs) for localities that minimize total cost of capacity at the level of excess condition while maintaining the reliability criterion and not exceeding transmission security limits.

The NYISO plan evaluates net energy and ancillary services revenue at different levels of installed capacity using data from the most recent of either the capability year after a quadrennial “demand curve reset” or the annual update.

The ISO has incorporated into the proposed Tariff revisions incremental revisions recommended by stakeholders at the Feb. 6 Installed Capacity Working Group/Market Issues Working Group meeting, Stines said.

BIC Rejects On Ramp/Off Ramp Changes

The BIC also voted against recommending that the Management Committee approve a market design proposal and related Tariff revisions for eliminating localities and revising the existing on ramp/off ramp rules to create a new locality.

Zachary Smith, manager of capacity market design, told the BIC that the proposed methodology is based on reliability planning principles developed to determine whether to create and eliminate localities.

The proposed design was intended to make locality price signals direct investment to supply that provides the greatest reliability benefit.

Mark Younger of Hudson Energy Economics called the proposal “a flawed market design.”

“It is attempting to use the transmission security test to estimate a resource adequacy requirement,” Younger said. “The result of the NYISO’s test as proposed is that it will understate the resource adequacy needs and would therefore result in creating localities too late and eliminating them too early.”

Mukerji said that while the ISO has fully mapped out its resources and budget for the year, stakeholders could choose to juggle priorities in a related working group to make room for reworking the on ramp/off ramp proposal.

PJM Board Punts Capacity Market Proposals to FERC

By Rory D. Sweeney

PJM’s Board of Managers will ask FERC to choose between proposals by its staff and its Independent Market Monitor to insulate its capacity market from state-subsidized generation.

Rather than choose just one of the capacity reform plans on offer, the board instead voted Wednesday to direct PJM staff to file both the capacity repricing proposal it recommended and the MOPR-Ex proposal promoted by the Monitor.

“The board has decided that reform is necessary,” CEO Andy Ott wrote in a letter to stakeholders Friday. “The board has chosen a path that will definitively move the policy question to FERC while proposing a process that maintains opportunities for active, continuing involvement from stakeholders.”

Each proposal “represents a distinct, just and reasonable policy alternative to address the consequences of state intervention” in energy markets, Ott said.

“Deciding between these policy options requires a balancing of federal and state interests, raising questions of federalism and comity that have already presented themselves before the courts, including the U.S. Supreme Court.”

The board didn’t disclose its determination until Friday in order to develop an explanation for its decision. The vote came after a flurry of politicking over the past week from stakeholders, who sent seven letters to the board, almost all of which asking that the board not support PJM’s plan. Exelon was ambivalent about the RTO’s plan but asked that the board reject the Monitor’s plan.

The decision moves PJM another step closer to culminating the work of the Capacity Construct/Public Policy Senior Task Force (CCPPSTF) that dominated stakeholder activity in 2017. Stakeholders were at one point considering 10 different proposals, but the field eventually narrowed to proposals from PJM and the Monitor.

PJM said its plan would accommodate generator offers from state-subsidized plants by allowing them to bid into capacity auctions but ensure they don’t suppress competitive prices by removing those offers in a second “repricing” stage of the auction.

The Monitor’s proposal, known as MOPR-Ex, would extend the RTO’s minimum offer price rule (MOPR) to all units indefinitely, but in alternative versions it included carve-outs for states’ renewable portfolios and public power self-supply. Stakeholders, who saw the Monitor proposal as having the least impact on the current construct, backed it all the way to the Markets and Reliability Committee, but all of its different versions stalled there last month after Ott announced he would be recommending the RTO’s plan to the board no matter the outcome of the vote. (See “No Consensus on Capacity Revisions,” PJM MRC/MC Briefs: Jan. 25, 2018.)

The board’s decision represents a win for Monitor Joe Bowring, who had been maneuvering for months to navigate his proposal to stakeholder endorsement despite PJM’s clear indication that it would not support the proposal.

The board directed staff “to present the advantages and tradeoffs associated with each policy approach,” Ott said. Staff should make their preference known in the filing, but that “should the commission decide instead on a policy of mitigation, PJM believes MOPR-Ex would be effective in preserving competitive outcomes in PJM’s markets.”

The board also directed the filing to request “a time-bound settlement judge proceeding” after FERC chooses a proposal “with expectation that such a process will bring refinement, compromise and more consensus support for what ultimately will be presented to the commission later this year as a package of proposed rule changes.”

The board confirmed that the upcoming Base Residual Auction in May will proceed under the current capacity auction rules.
