ERCOT: No Consensus on Operating Reserve Changes

By Tom Kleckner

AUSTIN, Texas — ERCOT will send state regulators a white paper that outlines potential revisions to its operating reserve demand curve (ORDC) but makes no recommendations because of a lack of consensus on the need for changes.

The Technical Advisory Committee unanimously endorsed the white paper Thursday as “responsive” to questions Public Utility Commissioner Ken Anderson raised regarding the ORDC’s performance last summer.

In a memo to his two fellow commissioners in October, Anderson called for a PUCT review of the methodology behind the ORDC, a price adder intended to reflect the value of reserves.

ERCOT instituted the ORDC in June 2014 in response to a PUCT order. Energy and reserves were previously priced separately, and ERCOT could show low energy prices during a reserve shortage, creating reliability concerns.

‘Unexpected’ Results

Anderson said the ORDC was an improvement. During late summer, however, he said it produced “unexpected” results, citing Aug. 13, when he said “the ORDC adder did not seem to reflect appropriately” a reduction in physical responsive capacity (PRC) — online generation able to quickly respond to system disturbances.

ERCOT operators can take out-of-market actions, such as calling Energy Emergency Alerts (EEA), when PRC drops too low. On Aug. 13, operators deployed non-spinning reserve service (NSRS) as the PRC dropped to 2,371 MW. However, real-time online reserve capacity (RTOLCAP) was 3,629 MW and wholesale prices reflected that availability.

Anderson’s memo — known as “the Aug. 13 memo” — questioned whether the inputs used to calculate the loss-of-load probability should be reevaluated. “I ask the question because at certain hours of certain days last summer the price adder resulting from the ORDC seem to suggest [a loss-of-load probability] of well under 1%, even though ERCOT was considering making conservation appeals.”

Some stakeholders quoted in the white paper cited Anderson’s observation, saying the incident demonstrated that the ORDC “is not aligned with operations.”

Other stakeholders said that the ORDC is performing as intended. “There was sufficient additional offline generating capacity not counted in PRC available to the system during the 8/13/15 event, so it was appropriate for ORDC to recognize a low loss-of-load probability,” the white paper said.

The Aug. 13 incident came just three days after ERCOT set a new peak demand of 69,877 MW.

ERCOT staff said the initial assumption was that the behavior was related to ORDC. However, it has since determined the event is related to how available reserves are counted.

Coordinated Review

Anderson suggested PUCT staff coordinate their work with ERCOT’s in reviewing ORDC parameters. That includes the 2,000-MW threshold for operating reserves and whether they should be more closely correlated with the PRC, the value of lost load (currently $9,000/MWh), the calculations that go into the ORDC’s loss-of-load probability curve and other data inputs.

ERCOT’s Supply Analysis Working Group developed the 14-page white paper to address each of Anderson’s bullet points and provide more informed discussion on his request. It collects stakeholder recommendations and staff analysis, but the paper “is not intended to address any threshold issues such as what an appropriate reserve margin is for the ERCOT region or how it should be attained,” it said.

The paper also was endorsed by ERCOT’s Wholesale Market Subcommittee, though it was careful to note the endorsement “does not reflect any unanimous recommendations by either WMS or SAWG.”

SAWG stakeholders did agree that operators should not be given additional discretion in calling an EEA and that the “effective price cap” should remain at $9,000/MWh.

TAC Chair Randa Stephenson, of the Lower Colorado River Authority, praised the working group for its “Herculean effort in a short amount of time” before making it clear to the committee what it was endorsing.

“We’re not endorsing the white paper, because there are lots of ideas but little discussion. But we’re endorsing the white paper as being responsive to Commissioner Anderson,” said Stephenson, newly re-elected as the TAC’s chair.

ERCOT staff will file the white paper while staff, stakeholders and PUCT staff continue their ORDC review.

ERCOT Explains Delay in CRR Auction Results

On another matter, ERCOT staff explained a recent three-day delay in posting the results of February’s monthly congestion revenue rights (CRR) auction as a result of “new, unidentified software behavior that was not compatible with our procedures.” Staff said the error was not identified until CRR systems attempted to transfer auction transactions to the settlements systems and pre-assigned CRRs were not priced in the auction.

Market participants were notified the CRR auction was invalid 6 ½ hours after the incorrect results were initially posted Jan. 14. Updated results were posted almost 72 hours later, on Jan. 17.

Staff told the TAC the issue can be resolved with process changes.

Protocol Revision Requests OK’d

The TAC also unanimously approved eight protocol revision requests, ranging from aligning protocols with NERC reliability standards to reactive-power testing requirements:

NPRR691, Alignment of Protocols with NERC Reliability Standard BAL-001-TRE-1;
NPRR713, Reactive Power Testing Requirements;
NPRR720, Update to Settlement Stability Reporting Requirements;
NPRR734, Digital Attestation Signature Authority Expansion;

MISO Seeks Adjustments on Capacity Import Limits

By Amanda Durish Cook

MISO told FERC last week that it needs to adjust the formulas in its calculation of capacity import limits to avoid reliability problems.

The RTO made its case in a request for clarification Friday in response to FERC’s Dec. 31 order to change the way it conducts capacity auctions (EL15-70, et al.).

FERC said MISO’s $155.79/MW-day maximum bid was too high and that its approach to determining capacity import limits doesn’t take into account counter-flows. (See FERC Orders MISO to Change Auction Rules.)

MISO addressed the maximum bid issue in a compliance filing in which it submitted rule changes to set the initial reference level — part of the calculation of the opportunity cost of exporting capacity to PJM — to $0/MW-day. But it said it needs two adjustments to FERC’s order regarding its treatment of capacity imports.

Illinois Attorney General Lisa Madigan and the Illinois Industrial Energy Consumers also filed a clarification and rehearing request Friday.

New Year’s Eve Order

FERC’s New Year’s Eve order found that MISO’s calculation of local clearing requirements is unjust and unreasonable “because it could underestimate the impact that counter-flows from capacity exports have on the capacity import limit.”

The commission ordered MISO to adopt the Independent Market Monitor’s recommendation that adds back the amount of capacity exports included in base power transfer to eliminate the negative impact that capacity exports have on the calculation of the capacity import limits.

However, MISO said that two adjustments need to be made to comply with the order and maintain reliability.

First, the RTO proposes to remove the impacts of exports from the capacity import limit calculation. “If the full value of the exports must be realized exclusively through revisions to the capacity import limit, the capacity import limit calculation may overstate system capabilities, thereby causing a reliability problem,” MISO wrote.

MISO also asked to subtract the amount of exports from non-pseudo-tied resources from the local clearing requirement. In prepared testimony, Laura Rauch, MISO’s manager of resource adequacy coordination, said pseudo-tied units cannot be relied on because their “output is not directly available to the MISO region to relieve a constraint or in the case of an emergency.”

MISO said FERC should “recognize the benefits exports can make in terms of satisfying local resource requirements.” Rauch said that non-pseudo-tied resources that export their power outside of MISO can still meet local resource needs if needed during peak loads because MISO retains dispatch control over the resources. Rauch said the compromise would “accurately remove the impacts of exports from the capacity import limit calculations while acknowledging the support that these units may provide for their local resource zones.”

MISO’s position was supported by an affidavit from Market Monitor David Patton.

Should FERC refuse to clarify or grant rehearing, MISO asked the commission to allow it to employ its revised calculations to the 2016-2017 Planning Reserve Auction without an auction results resettlement. The auction is scheduled for April 1.

Illinois Wants ‘Going-Forward’ Costs Cleared Up

The IIEC and Madigan also sought clarification or rehearing on the Dec. 31 order, worried that “going-forward costs” could be interpreted to include sunk costs.

“The commission should clarify that the going-forward costs used to calculate facility-specific reference levels may include only prospective fixed costs that would be avoided by shutting down the facility during the forthcoming MISO planning year… The plain language of the term ‘going-forward costs’ implies that the only costs that may be included are costs that have not yet been incurred,” the two parties wrote in a joint filing.

The Illinois parties are also asking that FERC explain “the procedure to be employed by the Independent Market Monitor for calculating lost opportunity costs in establishing facility-specific reference levels.”

MISO Chief Operating Officer Richard Doying said during a Jan. 26 Markets Committee of the Board of Directors meeting that MISO will make a second compliance filing by March 30. To increase capacity supply and lower prices in the future, FERC gave MISO 90 days to develop default, technology-specific avoidable costs in time for the 2017/18 capacity auction.

In addition to FERC-ordered changes, MISO’s creation of a two-season capacity market could be filed by spring and help alleviate pricing concerns associated with the 2017/18 auction, Doying said. (See MISO Proposes Two-Season Capacity Market.) Doying said he would have more details on MISO’s response to PRA changes in June, after filings are made.

FERC Denies AEP’s Capacity Performance Waiver Request

By Michael Brooks

FERC last week denied American Electric Power’s request for a waiver of nonperformance penalties under PJM’s Capacity Performance construct for delivery year 2019/20.

AEP filed the request in November on behalf of four of its vertically integrated utilities that traditionally participate in PJM’s capacity market as fixed resource requirement entities rather than in the Reliability Pricing Model: Appalachian Power, Kentucky Power, Wheeling Power and Indiana Michigan Power. The company argued that the waiver would make it easier for its utilities to decide whether to remain FRR entities by the March 7 deadline.

“To be clear, if AEP makes the election to remain an FRR entity for the 2019/2020 delivery year … it will comply with the CP rules applicable to FRR entities, including submitting a capacity plan comprised of 80% Capacity Performance qualifying resources,” AEP said. “AEP seeks, simply for the sake of making that election in March 2016, a limited waiver of sections of the Tariff and [Reliability Assurance Agreement] imposing heightened nonperformance charges on FRR entities beginning in the 2019/2020 delivery year.”

AEP pointed to numerous factors making the decision more difficult:

Capacity Performance has not yet been implemented, and neither PJM nor market participants have any experience with the new rules. (Delivery year 2016/17, the first to include Capacity Performance resources, begins June 1.)
States in its service territories have yet to file compliance plans in response to EPA’s Clean Power Plan and EPA has not finalized its federal implementation plan, which would be imposed on states that do not file their own plans.
Several cases before the U.S. Supreme Court regarding federal vs. state jurisdiction over market resources, including demand response. (The court has since ruled on the question of DR, reversing a lower court’s decision voiding FERC’s jurisdiction over DR resources. See Supreme Court Upholds FERC Jurisdiction over Demand Response.)

Last year, the commission approved PJM’s Capacity Performance proposal, including the provision that FRR entities would be subject to the same nonperformance penalties as those participating in the auctions. Under the new construct, the resources in FRR entities’ capacity plans must be at least 80% Capacity Performance. The decision to include FRR entities was opposed by state regulators, who saw it as infringing on state jurisdiction by effectively eliminating states’ choice to opt out of the capacity auction process. (See FERC OKs PJM Capacity Performance: What You Need to Know.)

FERC was not convinced. The uncertainties faced by AEP are not unique to the company, the commission said. It suggested that AEP’s utilities should simply elect to remain as FRR entities for now and reconsider its decision next year after gaining experience under Capacity Performance. “We disagree that AEP’s election requirements are different from other similarly situated resources deciding whether to select the fixed resource requirement alternative or to participate in PJM’s RPM capacity auction,” FERC said.

The commission was also unpersuaded by AEP’s claim that the waiver would not harm any other market participants. Granting the waiver would not be fair to other FRR entities who did face nonperformance penalties, FERC said.

AEP’s request was opposed by PJM, the Independent Market Monitor for PJM, the PJM Power Providers Group and the Electric Power Supply Association. The Indiana Utility Regulatory Commission supported the waiver, arguing that RPM participants had more flexibility than FRR entities, as the former are able to buy out of their future capacity positions in the RTO’s three Incremental Auctions.

The Base Residual Auction for delivery year 2019/20 is scheduled for May 11 to 17.

SPP, SaskPower Make First International Trade

OKLAHOMA CITY — SPP completed its first international transaction late last year, thanks to Canadian interconnections that came with the Integrated System’s addition to the RTO last year.

SPP Executive Vice President and COO Carl Monroe told the Regional State Committee last week that SaskPower, the principal electric utility in Saskatchewan, came to the RTO’s aid during a mid-December “emergency situation” in North Dakota. Monroe said SaskPower was able to “facilitate power” during a storm and after some transmission outages via existing interconnections in the state.

The RTO would not divulge additional details, claiming market sensitivities.

Bruce Rew, vice president of operations for SPP, told the committee the Integrated System also has helped with market-to-market congestion between the RTO and MISO.

The system “is very integrated with MISO in the upper Midwest,” Rew said. “The market solutions with IS seem to be working very well for us.”

SPP CEO Nick Brown thanked the committee for “being instrumental in helping us engage with your states” as the grid operator prepares to help its region comply with EPA’s Clean Power Plan.

“We, as SPP staff, have been asked to assess the impacts of implementation,” Brown reminded the committee. “We do continue to urge regional approaches over state-by-state approaches … but the biggest challenge for us is we don’t know what to plan for yet.”

Last week’s quarterly RSC meeting was the first led by Patrick Lyons, chairman of the New Mexico Public Regulation Commission. Lyons welcomed Nebraska Power Review Board member Dennis Grennan as the committee’s 10th and newest member.

Utilities’ Restoration Plans Pass FERC, NERC Review

By Rich Heidorn Jr.

A joint FERC-NERC review of nine unnamed utilities’ system restoration and recovery plans found them “for the most part … thorough and highly detailed” but also identified room for improvement and called for additional studies.

“The reviewed plans require identification and testing of black start resources, identification of primary and alternate cranking paths, and periodic training and drilling on the restoration process under a variety of outage scenarios,” the report said. “Likewise, the joint staff review team found that participants had extensive cyber security incident response and recovery plans for critical cyber assets covering the majority of the response and recovery stages.”

Staff from FERC, NERC and Regional Entities gathered information from “a representative sample of nine registered entities with significant bulk power grid responsibilities, including some entities that are registered with NERC in multiple functions.” The report emphasized that the staff review “was not a compliance or enforcement initiative.”

The report identified several opportunities for improving readiness through measures including improving the clarity of some NERC reliability standards.

It also took note of best practices used by some participants that went beyond NERC requirements, such as the inclusion of illustrations and step-by-step procedures in restoration plans and conducting drills that involve the actual transfer of control center operations to an alternate site. “The actual evacuation and verification of functionality of recovery resources can reveal unknown issues or problems through use of the alternate site’s cyber assets,” it said.

Recommended changes included:

Clarification on when system changes will trigger a requirement to update restoration plans. “In considering these measures, the kinds of events that may warrant an update to the system restoration plan should be identified, taking into account the length of time the system is affected, as well as the overall objective of ensuring that restoration plans are generally flexible enough so that system modifications can be addressed without continuous updates.”
Exercises and drills testing the transition from transmission operator island control to balancing authority area control error and automatic generation control.
Cyber security incident response plans and recovery plans for critical cyber assets should designate accountability at the cyber asset level (e.g., energy management system (EMS) servers, remote terminal unit concentrators, network routers).
More detail on the types of cyber security events that should trigger a response and reports. “While the team recognizes that [Critical Infrastructure Protection] version 5 will require responsible entities to have processes to identify cyber security incidents, consideration should be given as to whether any additional clarification or improvements are needed once some experience is gained with CIP version 5,” which takes effect for some assets on April 1.
Expanding the use of cyber security technical expertise and advanced technical tools.
Reducing the risk of recovery plan “inventory assumptions.” It said “entities may assume that hardware from external sources or other third-party vendor support needed for recovery of critical cyber assets will be available, without necessarily having measures to ensure availability. Likewise, entities may not consider interdependent or common-mode failure scenarios, which can create the need to recover multiple critical cyber assets concurrently from the same vendors.”

Among the studies recommended were:

Assessing system restoration steps that may be difficult if operators lose supervisory control and data acquisition computer systems, inter-control center communications protocol or EMS functions.
Identifying factors to be considered for replacing black start resources, including locational diversity and dual-fuel capability.
Determining the benefits of including existing or future voltage source converter DC lines in restoration plans.

Companies Propose Multi-state Projects in New England

Hydropower and wind power developers have submitted two proposals to supply electricity to three New England states to meet renewable energy goals. Rhode Island, Connecticut and Massachusetts jointly solicited projects for more than 5,000 GWh of clean energy.

Anbaric Transmission and National Grid proposed building the 60-mile Vermont Green Line transmission system to deliver 400 MW of hydropower from Canada and electricity from a proposed wind project in Beekmantown, N.Y. The line would be buried along public roadways and underneath Lake Champlain to connect with the ISO-NE grid.

Central Maine Power and Emera Maine proposed building about 150 miles of new transmission lines and substations to deliver up to 1,200 MW of electricity from wind projects in the northern part of the state that are planned or under development. The Maine Renewable Energy Interconnect project would largely follow existing rights of way.

Mo. Lawmakers to Wash. State: More Time on Colstrip Plant

A delegation of Montana lawmakers recently made a pitch to their counterparts in Washington state to save the coal-fired Colstrip power plant — or at least give them time to plan for a partial shutdown.

A bill before the Washington State Legislature would authorize Colstrip’s largest owner, Puget Sound Energy, to file a plan to decommission Colstrip’s two oldest units and to allow the utility to buy additional ownership in one of the two newer units.

Four Montana lawmakers told a Washington State Senate committee on Jan. 20 even a partial shutdown would have dire economic consequences on the southeastern Montana community of Colstrip and on industrial users across the state that depend on cheap power from Colstrip Units 1 and 2.

AWEA Says Iowa Edges out California as No. 2 Producer

Iowa now is the second-largest wind-production state in the nation, edging past California in the annual rankings compiled by the American Wind Energy Association. Iowa now has about 6,000 MW of installed capacity, with the addition of about 300 MW in the fourth quarter of 2015.

Texas remains No. 1 with nearly 18,000 MW of installed capacity.

AWEA Manager of Data and Analysis John Hensley said about 5,000 MW of wind came online in the final quarter of 2015, the highest quarterly improvement since the fourth quarter of 2012. In both years, federal tax credits supporting wind production were set to expire, triggering a surge in construction.

Groups Challenge NIPSCO Fixed Rate Hike

The Citizens Action Coalition and the Environmental Law and Policy Center are challenging Northern Indiana Public Service Co.’s proposed 82% increase in the monthly fixed charge for residential customers, saying the boost from $11 to $20 would inordinately affect low-income, minority and elderly customers.

The consumer organization and the environmental group told the Utility Regulatory Commission that the proposed fixed-rate increase would also undermine the viability of energy efficiency programs. The groups urged NIPSCO to improve assistance to low-income customers.

NIPSCO says the rate increase is necessary to defray costs such as $95 million spent on distribution improvements and $90 million spent on meter replacements. The utility says that most of a customer’s bill would still be associated with the volume of electricity consumed, retaining an incentive for customers to conserve.

State Delays Controversial Plant After Lawmakers Raise Concerns

Gov. Sam Brownback’s administration is suspending plans to build a new power plant in Topeka after lawmakers raised concerns about the project’s cost.

The Department of Administration, which oversees the state’s facilities, struck a $19.9 million deal with Bank of America in December to finance construction of a new energy center, which would provide heating and cooling for the capitol and four other state office buildings. Lawmakers of both parties raised concerns that the tax-exempt municipal lease with Bank of America was made without legislative approval.

“[Lawmakers] asked for some more time,” said Brownback. “We followed the proper process, but if they think there’s ways that we can save money, I’m willing to let people take more looks at those items.”

DEQ Wants Better Records of Underground Natural Gas Storage

The Department of Environmental Quality wants energy companies to keep better records of underground natural gas storage infrastructure in light of a continuing Southern California methane gas leak involving a failed 61-year-old pipe.

Some of the state’s aging natural gas storage facilities have been in place since 1941, and the DEQ is worried that utilities like DTE Energy and Consumers Energy aren’t reporting enough on the condition of their storage infrastructure. In 2013, the state had more natural gas stored underground in depleted gas formations than any other state: 58 storage fields containing 1.1 trillion cubic feet of natural gas.

“If a piece of steel has been in the ground for 60 to 70 years, it could be corroded,” William Harrison, a geosciences professor at Western Michigan University, told MLive. “That’s why they monitor and test these wells on a regular basis.”

PSC Says Net Metering Rule Stands for now

The Public Service Commission declined to reconsider its new net-metering rules for solar customers, which have attracted criticism from solar advocates as well as trade associations representing electric cooperatives.

The new rules, approved in December after a five-year drafting process, provide for net-metering customers to receive credit for 7 cents to 7.5 cents/kWh of power distributed on the grid. Solar advocates had proposed the customers receive the going retail rate, which is about 10 cents/kWh for customers of Entergy, one of the state’s two investor-owned utilities. The utilities had sought a lower rate.

The Electric Power Associations of Mississippi, which represents distribution cooperatives, and the South Mississippi Power Association, a transmission and generation cooperative, asked the PSC to reconsider the rules, saying they were an illegal intrusion into retail rate-setting. Entergy said it was satisfied with the rules as passed and is “moving forward with net-metering implementation.”

PSC: NorthWestern Must Explain Tax Burden Portion of Bills

The Public Service Commission last week voted 4-1 to require NorthWestern Energy to spell out how much of customers’ bills goes toward paying company taxes. The regulators criticized a state law that permits NorthWestern to pass its tax burden along to ratepayers directly with little control from the PSC.

“Year after year, the Department of Revenue uses an extremely subjective method to calculate NorthWestern’s property taxes. State law then sticks ratepayers with the bill,” PSC Chairman Brad Johnson stated in a press release. Legislation to end the pass-through failed to gain traction in 2015 in spite of the commission’s unanimous approval.

“The automatic pass-through of taxes to NorthWestern’s customers is nothing more than a hidden sales tax on energy,” said PSC Vice Chairman Travis Kavulla. “Consumers deserve to know what they are really paying for.”

CPP Requirements Could Cost Some Montanans $178 Annually

Montana-Dakota Utilities customers could end up paying an extra $178/year if the utility has to upgrade its coal-fired plants to meet new federal environmental standards.

The Public Service Commission is meeting Feb. 9 to determine whether to sign off on MDU’s 21% rate increase request, some of which would go toward upgrading its coal-fired plants.

MDU’s plan to upgrade its plants may not be sufficient to meet the new Clean Power Plan standards, and some question whether the utility might be making a bad investment. “You shouldn’t want to make large capital investments in power plants that are then subject to other regulations that could shut them down,” said PSC Vice Chairman Travis Kavulla.

BPU Approves 28-Mile, $130M Nat Gas Pipeline

By a vote of 5-0, the Board of Public Utilities last week approved construction of a 28-mile natural gas pipeline, but the $130 million project still needs state and local approvals. The Southern Reliability Link, proposed by New Jersey Natural Gas, would run from Chesterfield, through military-held Joint Base McGuire-Dix-Lakehurst before terminating at NJNG’s system in Manchester.

Company officials and BPU President Richard Mroz have said the pipeline is necessary to provide supply reliability and to meet future demand.

The project continues to be hotly contested, however.

Jeff Tittel of the New Jersey Sierra Club had strong words against the decision. “This pipeline is not for resiliency; it is for growth and development along the coast,” he said. “The BPU does not listen to the people, they just do what the utility companies want,” he said. “Putting in this pipeline will be like putting a blowtorch in people’s backyards.”

Environmental Groups Plan Opposition to Four Corners Plant

A coalition of environmental groups has given legal notice that it plans to oppose the federal approval of operations at the Four Corners Power Plant and Navajo Mine.

The groups on Dec. 21 filed a 60-day notice of intent to sue the U.S. Office of Surface Mining, the U.S. Fish and Wildlife Service and other federal agencies for approving the Four Corners Power Plant and Navajo Mine Energy Project last summer. The approvals gave the coal-fired plant the ability to operate until 2041.

The environmentalists contend that the U.S. government’s impact study on the plant and the mine that supplies it was flawed. The groups claim the study failed to look at enough viable clean energy alternatives for power generation at the plant and failed to consider the impacts from carbon pollution.

Solar Tax Credit Bill’s Fate Uncertain in Legislature

Legislators have proposed extending a solar tax credit that is set to expire at the end of the year. A similar extension was approved with bipartisan support in both houses of the Legislature last year but was vetoed by Gov. Susana Martinez.

House Bill 26 would allocate $5 million annually for residents who install solar thermal or photovoltaic systems at their homes or businesses. They would receive a tax rebate of 10% of the cost of installation — up to $9,000 — until 2019. The proposed rebate will then decrease each year until 2024.

The current tax credit has been in effect since 2006, and over the last five years an average of $38 million has been spent installing solar panels. In 2014, 1,600 people were employed in solar jobs, according to the Legislative Finance Committee, and solar installations have grown an average of 81% between 2010 and 2013.

Mine Shutting down, Laying off 95 Employees

Dakota Westmoreland’s Beulah coal mine will lay off 95 employees in March and April as it winds down coal deliveries to the nearby Coyote Station power plant, which is switching suppliers.

The Coyote Station will start receiving coal in May from a new North American Coal operation called the Coyote Creek Mining Co., now poised to dig just to the southwest of Dakota Westmoreland. Dakota Westmoreland will retain 40 employees to produce the half-million tons it is scheduled to deliver annually through 2021 to another power plant.

Coyote Station is operated by Otter Tail Power, one of four owners, along with Montana-Dakota Utilities. Owners said they switched coal suppliers because North American offered a better price. Dakota Westmoreland, whose 9,000-acre Beulah surface mine complex produced 2.9 million tons of lignite annually, is owned by Westmoreland Coal.

Power Plant Emissions to Worsen Lake Erie Algal Blooms

Researchers say pollution from fossil fuel plants will contribute to severe algal blooms in Lake Erie, which are expected to double over the next 100 years.

Researchers Noel Aloysius, of Ohio State University, and Hans Paerl, of the University of North Carolina at Chapel Hill, said that along with fertilizer use, additional rainfall and runoff caused by the changing climate contributed to 2015’s unprecedented algal bloom in Lake Erie. The two said toxic algal blooms are putting Lake Erie’s commercial fishing industry at risk.

The researchers contend the emission of nitrogen oxides from fossil fuel plants, which run into the water, also exacerbated blooms.

State Paying Millions More in Wind Incentives than Planned

A controversial tax incentive designed to lure wind developers to the state has drained nearly $45 million from state coffers in two years, beyond what officials had expected.

The state tax commission paid wind companies $27.3 million in cash incentives for 2013, the most recent tax year for which data is available, up nearly 50% from $18.2 million claimed the year before. Lawmakers had anticipated claims would tally $19 million in 2018. Lawmakers approved the credit in 2001 in a line tacked onto a bill releasing money for boating safety.

Supporters and critics of the state’s zero-emissions tax credit agree that its impact will continue to grow as developers build wind farms to meet increasing demand for renewable energy.

FERC has rejected requests to reopen hearings on a plan to expand Spectra Energy’s Algonquin Pipeline project, saying its review of the environmental impacts was adequate. The decision means Spectra can go ahead with its plans to expand the line, which starts in New York state, crosses Connecticut and terminates in Massachusetts.

Several organizations had asked for either a stay or a rehearing, including the Allegheny Defense Project, Riverkeeper, individual landowners and several towns in Massachusetts and New York.

The expansion project will add 37.4 miles of pipeline and related compression facilities in New York, Connecticut and Massachusetts. A majority of the project, however, involves replacing existing pipeline in order to increase capacity to 342,000 dekatherms of gas a day.

Senate Dems Calling for EPA to Regulate Methane Leaks

Twenty-one U.S Senate Democrats are calling for EPA to step in and regulate methane leaks from oil and natural gas wells. The group is led by Sens. Brian Schatz of Hawaii and Sheldon Whitehouse of Rhode Island.

They charge that EPA’s most recent rules don’t go far enough to control methane, as the new regulations do not apply to existing wells drilled before the rules’ passage.

“Moving forward with this rulemaking would sustain our international leadership on this issue and put forward a precedent that other countries can follow, much as they have done with our current methane commitment,” the group’s letter states.

NGSA Weighs in with Complaint on FERC NOPR

The National Gas Supply Association said it has “numerous concerns” about a proposed FERC rule requiring RTOs to disclose more information about parties with which they do business. FERC issued a Notice of Proposed Rulemaking calling for more information to prevent market manipulation.

The commission held a technical conference on the NOPR in December. In post-conference comments filed with FERC, the association outlined some of its concerns, even though the rule is aimed at RTOs and ISOs, rather than gas suppliers.

Although the proposed compliance obligations would not apply directly to the production, sale or transportation of natural gas, the association said the vague language in the proposed rule could make NGSA members “connected entities” for providing such services to ISO/RTO market participants, the association said. The group is concerned that suppliers might be forced to disclose commercially sensitive information.

DOE, NM Regulators Reach Settlement on Nuke Waste Incidents

The Department of Energy, the New Mexico Environment Department and a number of contractors have reached a settlement regarding incidents at a nuclear waste site and the Los Alamos National Laboratory. The settlement provides for $74 million for environmental projects at the Waste Isolation Pilot Plant, as well as for Los Alamos and surrounding communities.

The projects include the construction of an offsite emergency operations center, replacement of drinking water lines at Los Alamos and a fund to pay for monitoring in the future. The settlement brings an end to struggles between federal authorities, state officials and contractors related to a series of nuclear waste mishandling and spillage events.

MISO: 2015 Record Year for Unit Commitment Efficiency

By Amanda Durish Cook

MISO’s operators met their targets for minimizing online generation on 99.2% of the days in 2015, a record.

“This represents the best annual performance MISO has ever achieved on this metric,” said Vice President of Human Resources Greg Powell. “This also represents the best year that MISO’s ever had on unit commitment efficiency.”

The operators’ performance is penalized for Reliability Assessment Commitment (RAC) unit commitments and rewarded when online generation is minimized and sufficient to meet demand and constraints. Each day that MISO operators miss the goal costs market participants about $200,000 in uplift charges. Powell examined unit commitment efficiency and other annual metrics during a short-term incentive presentation at the Jan. 26 Human Resources Committee of the Board of Directors meeting. About 84% of short-term incentives were paid out, compared to 2014’s 69% and 2006’s all-time record of 87%.

MISO gave staff excellent ratings for unit commitment, reliability and compliance performance and said all strategic goals were completed.

The lowest ratings were on metrics for cost efficiency improvement, the customer satisfaction survey and capital budget. The RTO also said the year’s customer satisfaction survey received a passing — “threshold-plus” — grade, with 81% of those surveyed providing an average rating of five or better from a seven-point scale.

MISO rated its market funding efficiency — a measure of shortfalls or surpluses in financial transmission rights funding — at 94.8%, earning it a threshold-plus grade.

Operations spending came in 1.2% over budget, earning an “excellent” rating.

In keeping with the reliability performance of the prior eight years, no severe failures or violations occurred in 2015.

“2015 was a pretty good year for MISO,” Powell summed up.

Board member Paul Feldman praised 2015’s operation, saying MISO resolved the year’s issues “quietly” and expeditiously.

MISO Director Judy Walsh said she would like the RTO to examine what drives incentive payout, as hitting the metrics is becoming “day-to-day” routine.

MISO Steering Committee Briefs

MISO and PJM will begin creating an alternative to their current pseudo-tie market rules during a Feb. 18 joint and common market meeting. The discussion will coincide with the retirement of MISO’s pseudo-tie task team in February.

In the 2016/17 planning year, PJM expects MISO to request 2,061 MW worth of new pseudo-ties. PJM has said it wants to address immediate concerns before June 1 and explore long-term alternatives to its current agreement with MISO sometime after. Among other changes, the RTOs want to develop an outage notification process, better firm flow entitlement considerations, accurate pricing based on unit location, calculations dealing with congestion and market-to-market settlements and improved LMP convergence. MISO and PJM staff met on Jan. 5 to review a preliminary operating guide.

Kent Feliks, American Electric Power’s manager of regulatory and RTO policy, asked if the proposed changes stemming from the meeting might affect pseudo-tie requests that are scheduled for March. Kim Sperry, MISO’s director of market engineering, said the Tariff changes resulting from the joint meeting might include an option for existing pseudo-ties to continue under current rules or adopt the new ones. MISO Senior Director of Regional Operations David Zwergel said the issue would be long-term with potential Tariff changes and “lots of discussion,” and he didn’t foresee instantaneous changes.

The RTOs’ meeting signals the end of MISO’s pseudo-tie task team, created last year. “We don’t plan on extending the task team. Its six-month life has run its course, and it’s served its duty,” Zwergel said, adding that remaining pseudo-tie issues could be assigned to the Planning Advisory Committee.

The Steering Committee unanimously passed a motion to assign two immediate pseudo-tie issues to the PAC: concern that the current transmission service request evaluation processes “do not appropriately capture pseudo-tie impacts to MISO’s transmission system” and whether pseudo-tied resources have an “obligation to inform the native balancing authority of the intent to suspend or retire.”

Stakeholder Redesign Continues with Training, Resource Adequacy Charter and Management Plan

Michelle Bloodworth, MISO’s executive director of external and stakeholder affairs, said stakeholder redesign training for chairs and vice chairs of committees and subcommittees should be completed by May.

Bloodworth called the redesign a “landmark decision,” saying it will reduce MISO’s stakeholder bodies by 29% and meetings by more than 20%.

She also said implementing the redesign shouldn’t interrupt other work in MISO’s entities. “Everyone is very cognizant that we don’t want to halt any work that’s moving through committees,” she said.

“I look forward to this time next year us taking a look back on [the progress of the stakeholder process],” MISO President and CEO John Bear said at an informational forum a day earlier.

Now, MISO is focusing on the timely posting of agenda information ahead of meetings. Part of the stakeholder redesign stipulates the posting of meeting materials seven days in advance of parent entity meetings. Bloodworth said in 2015, materials were posted on-time about 65% of the time for the PAC, Market Subcommittee and Reliability Subcommittee. She suggested that MISO parent entities strive for a 75% goal of on-time material posting ahead of meetings in 2016.

Under the redesign, MISO has already eliminated the Trading Hubs Task Force and created a Resource Adequacy Subcommittee (RASC) that will consolidate two working groups and a task force. (See MISO Redesign Proceeds with New Committee.)

The Steering Committee approved a draft charter and management plan for the newly formed RASC, set to replace the Supply Adequacy Working Group, Demand Response Working Group and the Electric and Natural Gas Coordination Task Force.

“The objective of the Resource Adequacy Subcommittee (RASC) is to provide input and policy guidance to MISO management and the Advisory Committee on all market and operational activities and processes that facilitate adequate planning resources within the MISO for the long-term planning horizon,” according to the subcommittee’s draft charter.

RASC meetings will be held on an as-needed basis and be open to all stakeholders. Bill SeDoris, director of MISO integration for Northern Indiana Public Service Co., said once the RASC has leadership, the charter and management plan will be “fine-tuned” to further refine RASC responsibilities, with a final plan and charter brought before the Advisory Committee on Feb. 24. The RASC will oversee MISO’s Loss of Load Expectation Working Group.

“This is just us getting the process moving,” said Steering Committee Chair Tia Elliott. “It’s a good place to start.”

SeDoris said some resource adequacy responsibilities outlined in the Market Subcommittee’s charter and management plan might have to be separated out for the RASC so the two subcommittees don’t replicate tasks. Despite the concern, Steering Committee members approved the MSC’s charter and management plan. Elliott said they could be revised later if necessary. The topic will be discussed at February’s Steering Committee meeting.

Study Contemplates New York REV’s Impact on System

By William Opalka

RENSSELAER, N.Y. — NYISO and the New York Public Service Commission have begun a joint study to determine how a changing generation resource mix will affect the bulk power system over the next 15 years.

The PSC outlined the study at the Wednesday meeting of the NYISO Management Committee.

The recently unveiled State Energy Plan, part of New York’s Reforming the Energy Vision initiative, set a goal of 50% renewable energy generation by 2030.

The PSC has started a proceeding to develop a clean energy mandate to reach the goal (15-E-0302). Gov. Andrew Cuomo has ordered rules completed by June. (See New York Would Require Nuclear Power Mandate, Subsidy.)

The study’s goals are to determine what mix of generation and distributed energy resources will be needed by 2030 to meet public policies, and what gas and electric transmission upgrades are needed to serve generation and maintain reliability.

“There are going to be significant renewable energy resources needed to comply with both the [federal] Clean Power Plan and the SEP,” said Leka Gjonaj, chief of the Bulk Electric System at the PSC.

Models would be run contemplating various scenarios for 2024 and 2030, extrapolating results from NYISO’s most recent transmission needs analysis. Sensitivities — such as the retirement of the Indian Point nuclear facility, high natural gas prices, high load levels and the reduction or loss of dual-fuel generation — will be included.

Another scenario contemplates compliance with the CPP under different schemes. The third is implementation of the SEP and REV.

The study would determine resource mixes under each scenario and the infrastructure needed to support them. Ratepayer impacts are outside of the scope of this study.

Some members of the committee questioned how the study can incorporate the clean energy standard when its rules have not been finalized.

The base case scenarios and sensitivity results of the study have deadlines that run from February to July, with a final report due Aug. 9.

The consultants in the study will be paid about $850,000, with about $550,000 coming from NYISO. The ISO will also be contributing about one full-time-equivalent employee on the project, although several staff members will participate.

Also participating are the New York State Energy and Research Development Authority, New York Department of Environmental Conservation, the Utility Intervention Unit of the Department of State and the New York Transmission Owners.
