SPP, MISO Try to Bridge Joint Study Scope Differences

By Tom Kleckner

SPP and MISO are inching closer to agreement on a second joint transmission study on their seams, though they continue to disagree how “targeted” a targeted study should be.

The two grid operators have agreed to conduct another transmission study this year, using the carbon-constrained scenarios in SPP’s 2017 Integrated Transmission Planning 10-Year Assessment and MISO’s 2016 Transmission Expansion Plan as starting points.

The study, to be completed in the first quarter of 2017, will use the needs identified in the regional studies to develop solutions that benefit both RTOs. It will model the years 2020, 2025 and 2030; SPP will have to create a model for 2030, which is not included in the 2017 ITP10.

MISO prefers limiting the study to the seams between it and the Integrated System, which joined SPP last October, while SPP favors looking at a broader geographic area.

Staff shared the draft scope with the RTOs’ Interregional Planning Stakeholder Advisory Committee on Aug. 2, with SPP’s Seams Steering Committee again taking up the issue Aug. 3.

MISO staff said it preferred to focus on process improvements this year, but it did propose that a set of five needs — three belonging to SPP, two to MISO — be included in the joint study. SPP suggested 10 regional needs, eight in its footprint and two in MISO’s, that it said would “provide the most value to be evaluated” in the Coordinated System Plan study.

Time Best Spent

MISO agreed to a joint study this year only after a May meeting of its Planning Advisory Committee. (See “MISO Rethinks Coordinated Study with SPP,” MISO Planning Advisory Committee Briefs.)

“We have to ask ourselves, where is our collective time best spent?” said MISO’s Eric Thoms, manager of planning coordination and strategy, in arguing against a broader study. “The 2014-15 [study] took three extra months. It took a herculean effort to finish … that’s the most diplomatic way to define it.”

“My impression was [MISO has] already decided what they want to do, and it’s up to us to convince them otherwise. I don’t like that position,” SSC Chair Paul Malone, of the Nebraska Public Power District, said at Wednesday’s meeting.

The IPSAC conference call also left some SPP stakeholders questioning the stakeholder meeting process. The Wind Coalition’s Steve Gaw expressed concern that the decision to use a targeted scope was made prior to the joint stakeholder meeting.

“I thought the [IPSAC] call was about defining the scope,” Gaw said at the SSC meeting. “It confused me that a decision has already been made about [the scope] being targeted.”

David Kelley, SPP’s director of interregional relations, agreed with Gaw. “The way you described it should have been the way to work,” he said. “We bring issues to the table, [and] we decide if they’re enough to warrant a study.”

Staff set an Aug. 24 deadline for stakeholders to submit comments on the draft scope. MISO has another PAC meeting scheduled Aug. 17 that could further clarify the study’s final scope.

The IPSAC has tentatively selected Sept. 7 to finalize the scope with stakeholders.

Task Force to Look at Non-Order 1000 Regional Cost Allocation

In a related matter, the SSC voted 8-5 to create a task force to revise a proposed business practice for regional cost allocation of seams projects outside FERC’s Order 1000 process. The task force will use a white paper that has already been through the stakeholder process to document the policy. The group will be chaired by Oklahoma Gas & Electric’s Jake Langthorn.

In November, FERC rejected SPP’s proposal to create a new class of seams transmission projects; staff has been trying to determine how best to respond ever since. (See FERC Rejects SPP Proposal for Seams Transmission Projects.)

MISO Market Subcommittee Briefs

MISO will monitor maximum generation procedures as a result of pricing errors during a late July max gen warning, the RTO’s Kevin Larson said at last week’s Market Subcommittee meeting.

Jeff Bladen, executive director of market services, said pricing corrections for the multiple scheduled resources and one emergency resource were “relatively small” and represented less than $1/MWh. (See “June Energy Prices Up Across Footprint; New Emergency Pricing Encounters Snag in July,” MISO Informational Forum Briefs.)

David Sapper of Customized Energy Solutions asked if MISO could have withdrawn the max gen warning.

Rob Benbow, MISO’s senior director of systemwide operations, said the RTO forecast that high loads would persist throughout the day. “It’s one of those things where you’ve got data saying one thing, but … the load did not materialize,” Benbow said.

In the coming months, Bladen said MISO would review the performance of the new emergency offer floors.

Task Team to Take on 5-Minute Settlement Issue

MISO has charted a course for achieving five-minute settlement calculations with the creation of a six-month-long task team.

John Weissenborn, MISO’s director of market services, said the task team will discuss which day-ahead, real-time and financial transmission rights charges might be impacted, and identify changes needed for the Tariff and Business Practices Manuals. It will then shape the subsequent compliance filing due this winter.

Weissenborn said MISO hopes to have five-minute settlement language completed by December. The RTO expects five-minute settlements of energy resources and operating reserves in place by January 2018.

Currently, MISO’s real-time settlement occurs with an hourly average price while real-time operating reserve settlements are already conducted on a five-minute basis.

FERC Order 825, issued in June, directed RTOs to align settlement and dispatch intervals in real-time markets by January 2017.

However, MISO said even after Order 825 is implemented, interchange transactions will continue be settled at the 15-minute intervals that were instituted last June, as the settlement is performed using five-minute prices.

Weissenborn said MISO will have to explain the continued used of the 15-minute interchange transaction settlements in the compliance filing to FERC. “I think we’ll be successful in explaining that,” he said.

Brian Garnett of Duke Energy asked if the RTO expects companies to provide information on a five-minute basis.

Weissenborn said MISO “spent a lot of time talking with SPP on their implementation.” He said SPP experiences roughly 10% of market participants reporting at five-minute intervals and uses a curve fitting to calculate the rest. Weissenborn said most companies within SPP continue to report meter information hourly.

MISO Wants Future Control in Flow-Control Resources

Beibei Li, a senior operations engineer, said MISO is evaluating the need for optimization of flow-control resources to follow a real-time dispatch target.

MISO says its flow-control resources “are not directly represented in the market dispatch process” and that its inability to control them leads to inefficiency in the physical flow. This inefficiency, the RTO said, could impact AC system dispatch and “introduce unnecessary losses and congestion across the surrounding AC system.”

The RTO envisions increased use of several types of flow-control resources in the future, including HVDC lines, phase shifters, variable frequency transformers and series compensation flexible AC transmission system devices, designed to increase control and power transfer capability on the network. (See MISO Grid Meets ‘Big Data’.)

Li said MISO wants to be able to optimize its fleet of flow-control resources by the fourth quarter of 2018.

MISO staff plan to return to the October MSC meeting to deliver an update with project objectives and rough work plan.

Real-Time Offer Enhancements Start Time Delayed, Storage Assignments Divvied Up

Bladen reported that MISO’s real-time offer enhancements project will be delayed more than a month while MISO runs additional software testing.

The project, which will allow market participants to make overrides to real-time offers in MISO’s portal, is now scheduled for an early September go-live date. MISO was expecting to have the project completed by the end of July.

Although real-time offer enhancements are on hold, energy storage work is moving ahead. Bladen said MISO has divvied up tasks related to creating a storage policy.

Clarifying a storage interconnection definition has been referred to the Planning Advisory Committee and Interconnection Process Task Force. The Resource Adequacy Subcommittee will tackle how behind-the-meter generation can participate in the capacity market and decide how a stored energy resource capable of providing four hours of continuous power can participate in the regulation market.

Bladen also said MISO has had a low response rate to its annual customer opinion survey. MISO sent out 1,200 requests for responses to market participants. Bladen said just 9% of companies had responded as of Aug. 2. “That’s quite low, even at this stage in the process. We would very much like to get above the 9% we’ve got so far,” he said.

The survey window was extended by a week and is open until Aug. 12.

FERC Certifies Settlement of Entergy’s 9th Annual Bandwidth Filing

FERC last week certified a settlement between Entergy Services and the Louisiana Public Service Commission in the corporation’s ninth annual bandwidth filing under its system agreement, saying it “resolves all issues of dispute” (ER15-1826).

Entergy filed the settlement in March. In April, FERC staff filed supporting comments and Louisiana PSC staff approved the agreement, which had been set for hearing and settlement procedures in October. (See FERC Sets Hearings for Entergy’s Cost Allocations.)

ferc, entergy — Entergy’s Nine Mile 6 Plant in Westwego, La. *Source: Entergy*

At issue was Entergy’s exclusion of its Arkansas subsidiary from the allocation of its operating companies’ 2014 production costs. The corporation’s cost allocation under its system agreement has been regularly challenged by regulators since it took effect in 2007.

Entergy’s six operating companies essentially operate as one system, although each has different costs. Payments are made annually by Entergy’s low-cost operating companies to the highest-cost company in the system, using a “bandwidth” remedy that ensures no company has production costs more than 11% above or below the system average.

Hundreds in Financial Limbo as Solar Credits Fade Away

Hundreds of rooftop solar users have been thrown into financial limbo after the state’s Department of Revenue warned in July that it had run out of money to fund tax credits intended to promote installations.

Lawmakers decided last year to cap the solar tax credit program in the face of worsening budget woes. Legislators also widened the cap to cover everyone who purchased solar in 2015, including those who bought their systems well before any changes were proposed.

The solar tax credit is among the most generous in the country, covering up to 50% of the first $25,000 spent to install a rooftop solar system, or up to $12,500 total. It can be combined with a 30% federal tax credit for extra savings. The program had a 2017 sunset, but lawmakers went a step further last year and capped credits for purchased systems at $25 million.

Kinder Morgan Pipeline Project Surveying Begins

Kinder Morgan surveyors are mapping the route of its proposed 2-mile natural gas pipeline, part of the three-stage $86 million Connecticut Expansion Project, through a state forest.

The state Department of Conservation and Recreation granted permission for surveying and marking the pipeline’s right of way through Otis State Forest. No permission for land clearing has been granted as the developers await FERC approval, and legal challenges to the project continue.

Opponents argue that the old-growth forest is protected by the state constitution, as the land was acquired by the state for conservation a decade ago at a cost of $5.2 million.

Governor Signs Clean Energy Bill

Gov. Charlie Baker on Monday signed a bipartisan bill that requires utilities to obtain 9,450 GWh annually of clean energy from large-scale Canadian hydropower, onshore wind power and solar, and 1,600 MW of offshore wind from developers who currently hold federal leases.

“Massachusetts is always at the forefront of adopting innovative clean energy solutions, and this legislation will allow us to build on that legacy and embrace increased amounts of renewable energy, including hydropower,” Baker said. The bill was passed a week ago in the waning hours of the recently concluded legislative session. (See Massachusetts Bill Boosts Offshore Wind, Canadian Hydro.)

AG Accuses Enbridge of Mackinac Safety Violations

Attorney General Bill Schuette says Enbridge Energy’s application to install more pipeline support anchors is evidence that the company’s Line 5 pipelines under the Mackinac Straits are currently in violation of safety standards, which require pipe-support anchors at least every 75 feet.

Enbridge recently submitted a request for a permit to install up to 19 additional anchors. The company says it informed state officials of the need for more support after a June inspection.

The company has been under heightened scrutiny since a 2010 pipeline break spilled more than 800,000 gallons of oil into the Kalamazoo River. In July, it agreed to pay $177 million to settle claims in connection with that spill.

Supreme Court Nixes Net Metering Referendum

The state Supreme Court last week unanimously ruled to block a referendum from appearing on the Nov. 8 general election ballot that could have restored favorable net metering rates to customers. The court ruled that the way the question was formed was “not only inaccurate and misleading, but also argumentative.”

The referendum question has been seen as a battle between NV Energy and the solar industry. The state, after heavy lobbying from NV Energy, set lower net metering rates this year. Many solar companies announced they were leaving the state, saying the new rates effectively suffocated the solar industry there.

Solar advocates expressed disappointment in the ruling, but said they would pursue alternative strategies. “We look forward to crafting strong solar policies that give Nevadans the freedom to power their homes and communities with clean solar energy,” said Erin McCann, campaign manager for Bring Back Solar.

Regulators, AG Doubt PNM’s Smart-Meter Claims

Public Regulation Commission staff have expressed doubt about the public benefits of Public Service Company of New Mexico’s plans to install advanced metering infrastructure (AMI), while eliminating the jobs of the 125 employees who monitor them.

Charles Gunter, accounting bureau chief for the PRC’s utility division, said the commission staff support the concept of advanced metering, but PNM’s projected costs to replace about 531,000 electricity meters “are uncertain and indicate that the AMI project would not produce sustained savings, compared to the existing metering system, until 2024.”

The attorney general’s office also submitted testimony from an expert witness, Columbia Group President Andrea Crane, who said the project would result in a net cost of $12 million instead of the net savings of nearly $21 million that PNM claims.

McCrory Denies Discussing Duke Coal-Ash Warnings

The state toxicologist said he discussed with Gov. Pat McCrory the “scientifically untrue” health advisories the state released that downplayed the risk of well water contamination near Duke Energy plants, but the governor’s office strongly denied ever having that conversation.

State Toxicologist Kenneth Rudo testified in a deposition that state-issued health advisories saying the water was safe to drink were wrong and that he told McCrory and other state officials. Rudo, in a later interview with The Charlotte Observer, said he spoke with the governor by phone for about four minutes and said he advised that well owners should be warned of the risk, as an earlier state-issued comment had done. Instead, the state issued a statement saying tests showed well water met federal clean water standards.

“We don’t know why Ken Rudo lied under oath, but the governor absolutely did not take part in or request this call or meeting as he suggests,” Chief of Staff Thomas Stith said in a statement. Lawmakers passed legislation calling for Duke to provide clean drinking water to affected residents.

State Working to Fill Abandoned Coal Mines

Contractors are pumping about 7,500 cubic yards of grout into an abandoned underground lignite mine, part of a project conducted by the Abandoned Mine Lands Division of the Public Service Commission. The drilling and grouting project will prevent dangerous sinkholes from forming as a result of mine subsidence.

The cost of the work is covered by federal reclamation fees on active coal mines. The division has conducted two major and one minor project this year; since its start in the 1980s, it has conducted more than 100 reclamation projects, usually finishing four to 10 annually.

Wilton was the focal point for state lignite mining in the early 20th century.

Mead Appeals to Interior On Coal Lease Moratorium

Gov. Matt Mead appealed to the U.S. Interior Department to end its moratorium on new coal leases in a 76-page letter with 4,179 pages of attachments sent to Secretary Sally Jewell and Bureau of Land Management Director Neil Kornze.

“States like Wyoming, where coal is produced and environmental stewardship is a model for the nation, were not consulted and were caught by surprise,” Mead wrote. “Now, national revenues, energy users across the nation, coal miners and their families are at risk. The justification for this moratorium and the manner it was unveiled are unjustifiable.”

Mead said the moratorium, announced Jan. 15, is dramatically impacting jobs, energy security and energy independence, and that it specifically targets the state, the nation’s leader in coal production. The state produces roughly 40% of the nation’s coal, most of which is mined from federal land.

Report: More EE Standards Under Obama than Any Other President

Under the Obama administration, the Energy Department has finalized more energy efficiency standards than under any other administration, a recent report said.

Regularly updating and creating energy efficiency standards has been part of the department’s duties since President Ronald Reagan signed the National Appliance Energy Conservation Act in 1987. While the department has been publicly touting its progress, the report by two independent groups, the Appliance Standards Awareness Project and the American Council for an Energy-Efficient Economy, validates its claims. The department has adopted 45 standards under President Obama and will potentially adopt 10 more before his term ends next year.

The runner-up to Obama is President George W. Bush; under his presidency, 27 standards were adopted. Bill Clinton’s administration adopted the fewest with only six, the report said. Obama made energy efficiency a top priority for the department after it fell behind in its mandated update quota under Bush, according to the report.

NRC Issues Final Safety Report for Duke Nuke

The Nuclear Regulatory Commission issued the final safety evaluation for Duke Energy’s proposed Williams States Lee nuclear plant to be built in Cherokee, S.C., bringing the company one step closer to beginning construction. The commission found no safety issues to prevent the plant from being built.

Duke applied for the licenses in 2007 and received the commission’s final environmental impact statement in 2013, but it still hasn’t made a final decision on whether to go ahead with construction. That decision would come after the commission has issued the two necessary operating licenses, according to the company.

DOJ Opens Investigation into Westar-Great Plains Deal

Coming on the heels of a Missouri Public Utilities Commission staff recommendation that the commission should have jurisdiction over the pending $12.2 billion Westar Energy-Great Plains Energy merger, the federal Department of Justice is also looking into the deal.

Word of the Justice Department investigation came in a report Westar filed with the Securities and Exchange Commission. “We and Great Plains Energy intend to fully cooperate with the DOJ in its investigation,” Westar said in its filing, which did not give details about the reason for the inquiry.

The PUC staff filing said it is looking to see if it can claim jurisdiction, even though Westar operates only in Kansas. Great Plains operates in Missouri. “Staff maintains that all of the known evidence supports a determination that the proposed transaction is detrimental to the public interest and ought not be permitted to go forward,” the staff said.

EIA Predicts NA Carbon-Free Power to Grow to 45% by 2025

The Energy Information Administration projects that by 2025, energy generation from renewable and nuclear resources will grow from 38% to 45%. Part of the outlook is predicated on the recent agreement between the U.S., Canada and Mexico to attain a goal of 50% by then.

EIA also included energy efficiency in the figures, but it didn’t break out the three resources. It predicted a decline in coal-fired generation of about 13% by 2025 and an increase in natural gas generation by 4%. It noted that Canada has already attained a level of 80% clean energy generation, primarily because of its large hydroelectric capacity.

Mexico’s combined nuclear and renewables should grow to 29% by 2025, EIA said. The outlook assumes EPA’s Clean Power Plan is upheld.

White House Requiring All Agencies to Consider Climate

The White House Council on Environmental Quality last week issued guidance under the National Environmental Policy Act that requires all federal agencies to consider the environmental and climate implications of projects.

The directive requires agencies to quantify greenhouse gas emissions and note the potential climate change impacts of each project during the review process. “This increased predictability and certainty will allow decision-makers and the public to more fully understand the potential climate impacts of all proposed federal actions,” the council said in a statement.

The policy change was first proposed in 2010. Republicans complained that it would allow the Obama administration to institute regulations without congressional approval.

NRC Upholds Entergy’s ‘No Booze’ Policy at Vermont Yankee Plant

The Nuclear Regulatory Commission upheld Entergy’s zero-tolerance rule for alcohol at its Vermont Yankee nuclear plant. The commission’s decision was prompted by Entergy’s 2014 suspension and firing of an employee after unopened bottles of alcohol were found in a private vehicle.

A company panel of managers later overturned the suspension, but a further company review reinstated it. A company spokesman said the zero-tolerance policy extended even to empty alcohol bottles that were headed for recycling. “You can’t even have the perception” of alcohol on site, the spokesman said.

At the time of the violation, the plant, which has since been retired, was in full operation with 636 employees.

NRC Reviewing NextEra’s Plan to Correct Seabrook Concrete Issue

The Nuclear Regulatory Commission is reviewing NextEra Energy’s plan to address concrete degradation issues at its Seabrook nuclear generating station.

The degradation is being caused by an alkali-silica reaction (ASR) in the concrete throughout the plant. It was first discovered in 2009 when Seabrook employees found portions of an underground electrical conduit tunnel degrading. It has since been found in numerous walls throughout the plant.

ASR is a chemical reaction that forms a gel in some concrete mixtures. The moisture-caused reaction forms the gel, which then expands and forms cracks. Approval of NextEra’s plan is critical to NRC issuing a license extension.

FERC Approves Apple’s Solar Marketing Plan

FERC last week approved Apple’s application to sell solar capacity at facilities it owns in Nevada, Arizona and California on the wholesale market. The ruling allows it to enter the wholesale market with 20 MW of generation capacity in Nevada, 50 MW in Arizona and 130 MW in California.

“Based on your representations, Apple Energy meets the criteria for a Category 1 seller in all regions and is so designated,” FERC wrote in a letter to Apple attorneys.

Google also has received FERC approval to sell solar capacity into wholesale markets.

Despite Lengthy Negotiations, PJM Cost Allocation Settlement Still Finds Detractors

By Rory D. Sweeney

Years in the making, a settlement between PJM and transmission owners over the RTO’s procedure for allocating the costs of major transmission projects is receiving criticism from stakeholders that say they weren’t invited to the table.

The case has dragged on for nearly a decade, with FERC’s orders on how to allocate costs for transmission projects at or above 500 kV twice being remanded by the 7th U.S. Circuit Court of Appeals back to the commission.

PJM’s “postage-stamp” cost allocation for the projects was challenged by the RTO’s Midwestern utilities. The method billed all PJM utilities in proportion to their load, regardless of where the projects were located.

The commission had originally approved the postage-stamp method in 2007 and attempted to justify it in its order on remand. The court, however, ruled that FERC had again failed to show how a western utility would benefit as much as an eastern utility from new transmission facilities in the east. (See FERC Orders Proceedings to Decide PJM’s Postage-Stamp Cost Allocation.)

In June, after more than a year of negotiations, a large majority of stakeholders submitted to FERC a settlement that created a cost allocation formula for projects approved prior to Feb. 1, 2013, when PJM abandoned the postage-stamp method (EL05-121).

“The overwhelming majority of the PJM transmission owners and all of the state regulatory authorities that have actively participated in this proceeding are either settling parties or have agreed not to oppose the settlement,” the filing reads.

The agreement would require collecting fees from customers on the eastern side of PJM’s territory and distributing them to customers on the western side. For projects that have been or will be completed, the settlement assigns 50% of costs on a load-ratio-share basis and the remaining 50% under the solution-based distribution factor (DFAX) methodology — the same method used for regional 500-kV projects approved since 2013.

Abandoned or canceled projects would be assigned using the violation-based DFAX method. The charges would be retroactive to Jan. 1, 2016.

Retroactive Issues

The settlement didn’t sit well with Direct Energy and the Retail Energy Supply Association, which argued they were neither invited to participate in the settlement talks through the PJM stakeholder process nor informed that they’d be expected to pay for the result.

On Monday, RESA appealed the denial of a previous motion to intervene in the case. In the appeal, the group stated that the settlement would require its members to pay their allocated share retroactively, “even if the customers who should be billed for the amounts have migrated to another supplier.”

Under deregulation, customers of the load-serving entities that make up RESA’s membership can switch companies quickly, so LSEs aren’t able to pass along retroactive charges to those who’ve left in the interim, the group said.

The denial, written by Acting Chief Administrative Law Judge Carmen A. Cintron, called RESA “a party that is uninformed of the delicate and complex negotiations that transpired in its absence.”

“When entities wait unreasonably long to seek intervention, [FERC] has stated that they ‘assumed the risk that the parties would settle the case in a manner not to their liking.’ Such is the situation that RESA’s delayed request has created for itself,” Cintron wrote.

RESA said it only became aware of the proceedings by reading the published settlement and that its suggested changes would “create minimal, if any, disruptions.”

“This is not a situation where an intervenor seeks to scuttle a settlement,” RESA said.

The group suggested two options to solve the issue: change the date for when charges should go into effect to sometime in the future, or put the burden of recovering the costs on electric distribution companies.

RESA is “hopeful” its new arguments will allow it to intervene, spokesman Bryan Lee said.

Marji Philips of Direct Energy said her company estimates the settlement will cost eastern ratepayers about $287 million.

“The LSEs are going to wind up having to pay for these costs that everybody agreed should be rate-based, and the calculation when it was originally done was done incorrectly,” she said.

Comments Pro and Con

Direct Energy and RESA are not alone in their opposition to the settlement. Linden VFT, which owns merchant transmission facilities, said it would not receive benefits in the settlement commensurate with the costs it would incur. In filed comments, Linden said the solutions-based DFAX method is “unduly prejudicial” to companies like itself.

But many stakeholders filed comments in support of the settlement.

“Pennsylvania’s ratepayers have been unfairly burdened, since 2007, with an excessive portion of those costs associated with the transmission projects encompassed by the settlement,” the state’s Public Utility Commission said. “The settlement agreement resolves those inequities and establishes a more reasonable and equitable cost allocation for both previously incurred costs as well as costs yet to be recovered.”

PJM Board Halts Artificial Island Project, Orders Staff Analysis

By Suzanne Herel

The PJM Board of Managers has suspended the controversial Artificial Island transmission project pending a “comprehensive” staff analysis to be completed by February, at which time it will decide a course of action, CEO Andy Ott said in a letter to stakeholders Friday.

“It has become evident to all involved that the projected costs to resolve the problems at Artificial Island have increased significantly. PJM has been examining alternatives in an attempt to offset some of the increases,” Ott wrote. “In addition, questions have arisen about whether the currently proposed solution would perform as intended without further expense. Because of these concerns, PJM has come to the conclusion that a pause in the project is necessary before any new financial obligations are incurred by the project developers.

“In light of the current uncertainties around the changing scope and configuration of the project, it is imperative that we understand the basis for any alternatives that may exist to manage the operational issues at Artificial Island.”

FERC, DFAX, cost allocation, PJM, Artificial Island — Salem and Hope Creek Nuclear Reactors on Artificial Island *Source: Wikipedia*

This is the second time the board has overturned the stability project — PJM’s first competitive solicitation under Order 1000.

Initially, PJM planners recommended awarding the work to Public Service Electric and Gas, but the board reopened bidding to finalists following protests from spurned bidders, state officials and others. (See PJM Board Puts the Brakes on Artificial Island Selection.)

PSE&G, one of three entities eventually designated to build a 230-kV transmission line from the New Jersey nuclear complex under the Delaware River to Delaware, said Friday it was “committed to working with PJM and will provide PJM with any information and support they request.”

LS Power’s Northeast Transmission Development, picked to construct the transmission line, said Friday it was “disappointed” by the board’s action.

“The modeling errors in question do not relate to Northeast Transmission’s designated portion of the Artificial Island project and Northeast Transmission was not involved [in] the associated modeling activities,” it said. “Northeast Transmission was surprised by the PJM board’s decision, as Northeast Transmission had received no indication prior to the announcement from PJM on Aug. 5 that PJM had any concerns with PJM’s or PSE&G’s modeling of the system protection and control upgrades.”

Pepco Holdings Inc., chosen to work with PSE&G on the project, did not immediately respond to requests for comment.

The board approved the stability fix for the complex that houses the Salem and Hope Creek nuclear generators last summer. But in April, PJM revealed that PSE&G’s portion of the project — which the RTO initially pegged at $137 million — had nearly doubled to $272 million once the transmission owner completed a detailed analysis. (See Artificial Island Cost Increase Could Lead to Rebid.)

“PJM conducted a preliminary estimate regarding the interconnection to Salem,” a PSE&G spokeswoman said Friday. “We then conducted a detailed, design-level analysis of the interconnection to Salem. We had not previously prepared a detailed estimate for Salem because our proposal would have terminated in Hope Creek.” (See PSE&G Defends Artificial Island Cost Increase.)

The sticker shock prompted PJM planners to consider other alternatives, including terminating the line at Hope Creek.

“However, in reviewing this alternative, an issue arose related to one of the other components of the project: that is, whether proposed system protection and control upgrades would perform as intended,” Steve Herling, PJM’s vice president for planning, said in a letter to stakeholders Friday. “Specifically, PSE&G identified an error related to the modeling of circuit breaker clearing times associated with those upgrades. The effect would be a reduction in the margin of stability provided by those upgrades, regardless of any alternatives to the transmission solution under review, requiring further steps and expense to correct.”

In an informational filing with FERC submitted Friday, PJM said, “By virtue of this suspension, all designated entities are placed on notice to cease incurring any new financial obligations on the Artificial Island project until PJM completes its analysis and the PJM board has made a subsequent determination based on that analysis.”

The cost allocation of the project, the lion’s share of which would be charged to customers on the Delmarva Peninsula, led the governors, legislators and consumer advocates of Delaware and Maryland to oppose it. (See Del. Lawmakers Try to Block Artificial Island Plan; Project Still on Track.)

In June, FERC agreed to rehear its order approving the use of the solution-based distribution factor (DFAX) cost allocation method for the project. (See FERC Taking a Second Look at Cost Allocation for 2 PJM Projects.)

Neither of the letters PJM sent out Friday mentioned the cost allocation controversy.

Delaware Gov. Jack Markell released a statement commending the PJM board for its action.

“This decision is one that the state of Delaware welcomes,” he said. “The project as it was proposed would have placed an unjust burden on the state, resulting in higher electric rates for our consumers and businesses. I hope that upon further review, a more equitable solution can be identified.”

Bob Howatt, executive director of the Delaware Public Service Commission, said the agency was still analyzing the board’s decision.

“It seems like the political and economic concerns may have succeeded in stopping what has been called the most efficient and cost-effective solution because PJM and FERC have failed to address the cost allocation issue,” he said, adding that the decision seemed “totally unfair” to LS Power.

Howatt said he worried what effect the suspension would have on the desire of independent transmission companies to participate in the Order 1000 process.

“If I were an independent transmission company, why would I waste a lot of time on a project that could get overturned?” he said. “I just see it chilling the competitive transmission market that FERC has been attempting to create.”

UPDATED: Entergy Sells FitzPatrick to Exelon

By Tom Kleckner and William Opalka

Exelon announced Tuesday it has purchased the James A. FitzPatrick nuclear plant for $110 million from Entergy.

Officials from both companies were joined by Gov. Andrew Cuomo at the plant’s gates to announce the deal, which is subject to regulatory approval.

“We are pleased to have reached an agreement for the continued operation of FitzPatrick,” Exelon CEO Chris Crane said in a statement. “We look forward to bringing FitzPatrick’s highly skilled team of professionals into the Exelon Generation nuclear program, and to continue delivering to New York the environmental, economic and grid reliability benefits of this important energy asset.”

Entergy executives had reiterated last week that the company did not intend to continue operating the troubled plant in upstate New York beyond January 2017.

“There are no plans to continue to run the plant under Entergy ownership,” Bill Mohl, president of Entergy Wholesale Commodities, told analysts during the corporation’s second-quarter earnings call Aug. 2.

The company had announced plans to shut down both FitzPatrick and the Pilgrim nuclear plant in Massachusetts, but it recently said it had opened negotiations with Exelon over FitzPatrick. (See Entergy in Talks to Sell FitzPatrick to Exelon.)

Mohl told analysts if Entergy and Exelon are able to gain regulatory approvals for the transaction, refueling activities would begin in January. Otherwise, the decommissioning process would begin instead.

“We’ve made a commitment to reduce the size of the EWC footprint,” Mohl said. “If we’re unable to reach commercial agreements with Exelon or we’re not able to achieve those regulatory approvals, we’ll begin the regular decommissioning process and stay on the same path that we have previously been on.”

New York’s Public Service Commission on Aug. 1 unanimously approved 12-year subsidies for the state’s nuclear power plants on Lake Ontario, which have been buffeted by market forces. (See New York Adopts Clean Energy Standard, Nuclear Subsidy.)

Entergy reported second-quarter net income of $572.6 million ($3.11/share). That beat analyst expectations of $1.05/share, as polled by Thomson Reuters.

Revenue dropped to $2.46 billion, from $2.71 billion in the second quarter of 2015. The company said its March purchase of a 1,980-MW natural gas plant in southern Arkansas helped support revenue during the quarter.

Company shares, up 18.9% this year before the earnings announcement, have dropped 94 cents since, closing at $80.33 on Aug. 3.

ERCOT Technical Advisory Committee Briefs

AUSTIN, Texas — ERCOT’s Technical Advisory Committee last week rejected a request to allow economic dispatch of reliability-must-run (RMR) units over the objections of the ISO’s Independent Market Monitor and several of its Houston-area market participants.

NRG Texas drafted nodal protocol revision request 784, which addresses how RMR units are priced and dispatched, about the same time as ERCOT made its recent decision to extend into 2018 an RMR contract for NRG’s Greens Bayou Unit 5 near Houston.

The contract requires ERCOT to pay $3,185/hour for the duration of the agreement and an incentive factor of as much as 10% to reserve the 371-MW gas-fired unit’s capacity during summer months through June 2018. (See “Board Expands Greens Bayou RMR Contract to 2018,” ERCOT Board of Directors Briefs.)

NRG’s request would allow security constrained economic dispatch of RMR units to relieve transmission congestion after all other capacity available for transmission congestion relief had been exhausted.

ERCOT-IMM-Director-Beth-Garza-(RTO-Insider)-web — Garza © *RTO Insider*

Market Monitor Beth Garza supported the proposal, which she said would increase the dispatch price of RMR units, allowing other market units to be dispatched to resolve the constraint first.

In ERCOT’s energy-only market, an RMR agreement results from either a poorly designed evaluation process — which mistakenly identifies a resource as needed — or a failure of the market to provide sufficient revenue to justify continued operation of a needed resource, she said.

“Should the failure be in the RMR designation process, the resource is unlikely to be deployed and its energy offer price will be immaterial,” Garza said. “However, if the failure is in the market signal to units in this constrained area, the unit is likely to be deployed and the energy offer price will matter.”

Bill-Barnes,-NRG-(RTO-Insider)-web — Barnes © *RTO Insider*

Bill Barnes, NRG Energy’s director of regulatory affairs, said the request underscores the importance of sending the right price signals in the ERCOT market.

“We’re spending $60 million on an RMR contract for the months of June, July, August and September,” he said. “When you look at the State of the Market report for 2015, the real-time congestion rent for three of the major north-of-Houston constraints is $5 million. We’re spending $60 million to solve a $5 million problem. There are legitimate situations where the market solves the problem in a cheaper way. The boogeyman that is high prices gets pummeled by the boogeyman that is RMR.”

As drafted, NPRR784 would only apply when generator offers are mitigated because there is inadequate competition. RMR units are currently subject to the same offer mitigation as other units in such a situation, with Greens Bayou Unit 5 likely being offered at around $50-60/MWh. When there is adequate competition, RMR units are offered at $9,000/MWh under either the status quo or the NPRR.

The revision request would instead require all RMR units to be offered at the highest possible price that would still allow SCED to dispatch the unit for congestion. In Greens Bayou’s case, the estimates are as high as $700/MWh.

The NPRR failed to gain the Protocol Revisions Subcommittee’s endorsement during a roll-call vote July 14, but NRG appealed to the TAC. The revision request eventually fell short of the necessary two-thirds approval, with 54% positive votes and four abstentions.

NRG on Friday filed another appeal with the Board of Directors, which will consider the proposal at its Aug. 9 meeting.

“How do you prevent future RMR? By sending the right price signals,” Barnes said. “The presence of the RMR is evidence the market signal has failed. 784 addresses the most important RMR issue: How do you send the right price signal? It’s not a perfect solution, but is it better than what we have today? We believe the answer is yes.”

Garza supported Barnes’ position, although she also said she is a “huge believer” in ERCOT’s stakeholder process and “what this room can do.”

“Our position has been the objective of the RMR should be the price should be reflective of the unit not being there, but we should have the energy available to resolve the constraint,” Garza said. “It is absolutely a shortage condition. If that situation did not exist, Greens Bayou would be on the way to the scrap heap right now.

“I’m sympathetic to the argument that, ‘Gosh darn it, we spent $60 million on this unit, why can’t we use it?’” Garza said. “However, believe it or not, those are sunk costs … that don’t change if you resolve this situation. When you’re talking about resources necessary to resolve a transmission constraint, there are two factors: the offer price or mitigated offer cap, and the shift factor of the unit on that constraint — the effectiveness of that unit to relieve the constraint.”

“We generally agree with the IMM … but we disagree that 784 as a one-off is the solution,” said Energy Future Holdings’ Amanda Frazier, chair of the PRS. “We’re concerned [NPRR784] is reactionary. It doesn’t address whether Houston prices are high enough to allow RMR. If we pass this, we’re paying for incorrect price signals.”

Texas-Industrial-Energy-Consumers'-Katie-Coleman-defends-NPRR-784-(RTO-Insider)-web — Coleman © *RTO Insider*

Katie Coleman, with the Texas Industrial Energy Consumers group, represented the PRS position, arguing NRG’s proposal is punitive to loads, encourages unit retirements by providing scarcity pricing in non-scarcity conditions and prevents the RMR unit from solving other constraints beyond a single transmission line.

“We have concerns about requiring loads to also pay $600-800/MWh to use that unit for the very purpose it was placed under an RMR contract,” she said. “We have concerns about the incentive this creates for a generating company with a fleet of units in a certain area to retire units and get high pricing for its other units. [NPRR784] would require Greens Bayou to be priced at the highest possible price to solve, which would preclude it from solving other constraints in area.”

Noting that the revision request has been classified as urgent, Coleman said that electric retailers are concerned its requested September implementation timeline does not provide enough lead time for Greens Bayou and other generators in the area.

Coleman also noted customers are paying for Greens Bayou only until the Houston Import Project goes into service as early as 2018, when it is expected to solve the region’s congestion issues.

“This NPRR is sending a price signal too late to matter,” Citigroup Energy’s Eric Goff said. “The fact the contract exists is interfering with what would happen had the unit been allowed to retire. It gets to the point of whether there’s a weird incentive here.”

“If you’re a load outside of Houston, I have no idea why you’re not outraged,” Barnes said. “If the load in Houston has a small load-ratio share, I can understand why you would want someone else to solve your problem. We’re an energy-only market. Price signal is everything.”

Shortly after the TAC meeting concluded Thursday, ERCOT posted answers to questions it received from its request for proposals for must-run alternatives to the Greens Bayou RMR contract. (See ERCOT Seeks Alternatives to Houston-Area RMR Unit.)

Committee Discusses July 7 System Outage

ERCOT staff shared its analysis of the July 7 outage of its Energy Management System. The outage lasted 102 minutes and resulted in corrupted data being passed to downstream systems, including settlements and reports. Market participants said they saw a perceived drop-off in load and generation, but their primary complaints were around a lack of information coming from the ISO.

“When these things are occurring, I know ERCOT is scrambling to recover and get the grid stable again,” Barnes said. “From a market perspective, it was pure chaos. Market notices should be crystal clear about what is happening.”

“We just knew something was wrong because of operation notices,” Goff said. “Knowing the extent of the outage would be beneficial to the market.”

“We want to share with you the information we definitively know as quickly as possible,” said Kenan Ögelman, ERCOT’s vice president of commercial operations. “The tension we’re trying to balance is how long to hold information back until we can be sure” it’s accurate information.

The problem began at 11:41 a.m., when an operator mistakenly loaded test data into the active system, which corrupted data in the emergency system’s network model. Between 11:59 a.m. and 12:16 p.m., the market’s qualified scheduling entities were instructed to assume constant frequency control. By 1:23 p.m., the data had been corrected and verified, and operations returned to normal.

Corrected prices were posted for the affected SCED intervals, and staff said that it is continuing to evaluate alternatives that may affect subsequent settlements.

Price-Correction NPRR Approved

Barnes was successful with a second NPRR, dealing with ERCOT’s price-correction process following a SCED failure. NPRR696, which Barnes drafted on behalf of NRG subsidiary Reliant Energy Retail Services, passed with 72% of the vote.

“When the SCED system is not running, inputs grow stale. When it starts back up, things don’t make sense,” Barnes said. “It comes down to whether you believe the last best price, or whatever it spits out.”

NPRR696 establishes a price-correction policy that uses the last good price for settlement until ERCOT no longer requires manual action to stabilize the system. Barnes said that correcting prices for settlement intervals corresponding to the active watch period would give market participants transparency to known prices that reflect the last good SCED execution.

“This policy would extend that last good price for another 15 minutes,” Barnes said. “It could be the last high price or the last low price.”

The TAC unanimously endorsed six other NPRRs, a system-change request (SCR) and revisions to the Nodal Operating Guide (NOGRR), the Planning Guide (PGRR), the Retail Market Guide (RMGRR) and the Resource Registration Glossary (RRGRR).

NPRR738: Excludes from performance calculations intervals when an emergency response service generator is unable to meet its obligations because of transmission/distribution service provider (TDSP) outages.
NPRR747: Proposes new definitions related to voltage profiles, defines various entities’ responsibilities related to voltage support and clarifies that the interconnecting transmission service provider or its designated agent may modify a generation resource’s voltage set point.
NPRR767: Changes the eligibility check for the startup portion of the reliability unit commitment make-whole payment. Resources with lead times longer than six hours may submit a settlement dispute to have their resource-specific startup times considered when determining eligibility for startup costs included in the make-whole payment calculation.
NPRR770: Adds visibility and situational awareness to the market by posting the aggregate number of telemetered resources and their statuses to the ancillary service capacity monitor.
NPRR771: Clarifies that TDSPs must ensure an electric service identifier has been created in ERCOT systems before initiating electric service at a premises, avoiding related transactional, billing and out-of-sync issues.
NPRR774: Removes duplicate language regarding the calculation of seasonal transmission-loss factors.
NOGRR155: Clarifies voltage ride-through performance requirements for all generation resources immediately following a fault, stipulating that they must remain online and connected to the transmission system, and also maintain real power.
PGRR046: Aligns the planning guides with NERC’s TPL-007-1 reliability standard related to geomagnetic disturbances by specifying a process for developing geomagnetically induced system models.
RMGRR138: Removes the requirement for retail electric providers serving pre-pay customers to provide a weekly list of electric service identifiers to Oncor, replacing it with the requirement to provide the prepay list upon Oncor’s request.
RRGRR009: Adds three categories of data: voltage limits for resources’ substation transmission level equipment; geomagnetically induced currents and the presence of blocking devices to allow for the study of any vulnerability attributed to geomagnetic disturbances; and a most limiting single element (MLSE) allowing a resource entity to identify an MLSE on lines it doesn’t own.
SCR789: Updates the Network Model Management System topology processor to add a software tool commonly used by transmission-planning entities in ERCOT.
