MISO Stakeholders Provide Ideas on Incorporating Storage

By Amanda Durish Cook

As MISO contemplates expanding its definition of demand response resources to include medium-term energy storage, some stakeholders are asking the RTO to think more broadly about how storage technologies can participate in its markets.

MISO defines medium-term as any storage technology that can sustain output to the grid for four hours.

The RTO is challenged by how to accommodate four-hour capacity offers in its markets, as well as how to create a system of capacity credits and performance and must-offer obligations, Yonghong Chen, MISO principal advisor of market development and analysis, told the Market Subcommittee last week.

“These issues need to be thought through carefully,” Chen said.

MISO staff are discussing including medium-term storage in the DR resource-type II dispatch model, which facilitates offers into the markets for energy, regulation, spinning and supplemental reserves. Staff say they need more clarification on whether storage can be integrated under current market rules.

‘Formidable Task’

The Minnesota Energy Storage Alliance (MESA) says removing market barriers to energy storage is a “formidable task.”

“Our generation mix in MISO is evolving and energy storage technologies are becoming cost-effective in many applications,” MESA wrote in comments to the RTO. “MISO needs to keep pace with market changes in order to meet its obligation to provide unbiased regional grid management and open access to transmission facilities for [storage] projects.”

MESA contends that storage can cut consumer costs by storing “otherwise curtailed generation.” Storage should not be relegated to ancillary services, the group says, but could be dispatched — then redispatched — to supply grid services for more efficient generation. MESA thinks storage could be classified as both a generation and transmission service, and it encouraged MISO to develop new compensation mechanisms, such as CAISO’s flexible ramping product.

John Fernandes, director of policy and market development for Renewable Energy Systems Americas, also cautioned against strictly classifying storage as either generation, transmission or load.

“Such a practice could risk restricting a single storage plant from providing services across these operational buckets, thereby reducing the benefit realized by the system and limiting the ability to make a sound business case for storage development,” Fernandes said. He said that recognizing the fluidity of storage should not require significant Tariff changes.

Revenue Incentives

Manitoba Hydro said emerging storage technologies will require revenue incentives.

“If wind and solar dominate new resource development, storage will be increasingly needed, but, in the absence of an adequate revenue stream for storage resources, there may well be a market failure to supply them,” the company said.

The Energy Storage Association also sought more detail on how energy storage can participate in the MISO markets.

MISO said it would consider implementing a cost of new entry for storage, “similar to what is done for capacity resources.”

The New Orleans City Council said MISO’s January storage presentation posed several questions. (See MISO: Energy Storage Could Work into Existing Market Structure Next Year.)

“It may be difficult to prioritize actions needed to provide truly technology-agnostic products and operations when stakeholders cannot clearly identify barriers that storage developers and market participants face,” the council noted. Council members asked MISO to draft a storage issues statement.

Invenergy — which operates 68 MW of battery storage in PJM’s frequency regulation market but none in MISO — said the RTO has yet to clearly define the market need for storage. “Energy storage, and more specifically battery storage, is not the same as traditional generation and it should not be modeled or studied in the same way,” wrote Nicole Luckey, Invenergy manager of Midwest regulatory affairs.

Valy Goepfrich, WPPI Energy’s vice president of operations and analytics, said MISO’s suggested timeline on storage policy seemed reasonable and agreed that storage issues should be considered on a cost-benefit analysis.

Broader Discussion Sought

Chen said MISO is debating setting up an energy storage task force.

“Some of these issues are beyond the [Market Subcommittee],” he said. “I think we need a broader policy discussion.”

MISO must also determine whether storage will be used behind-the-meter to offset load, which wouldn’t require the RTO to manage the state of charge — a measure of a battery’s capability, akin to a fuel gauge — or if storage is placed in-front-of-the-meter, injecting into the system and requiring MISO to manage the state of charge.

Beyond incorporating medium-term storage, MISO also needs to decide if storage requires its own resource definition.

Chen said further market enhancements needed to incorporate storage might be recommended for MISO’s Market Roadmap process.

“Nothing’s off the table from my understanding,” said Jeff Bladen, MISO’s executive director of market design. “We just want to understand the implications.”

MISO staff this month will seek MSC advice on near-term clarification and present near-term proposals to the subcommittee. Next month, staff will begin drafting a white paper, which could propose Tariff or Business Practices Manual revisions. MISO hopes to present a final near-term storage proposal to stakeholders in late summer or fall.

Enviros Urge Ill. Legislators to Save Nuclear Plants

By Suzanne Herel

A coalition of scientists and environmentalists last week published an open letter to Illinois legislators, urging them to keep all of the state’s nuclear plants operating for their full lifetimes.

Clinton-Nuclear-Plant-(Source-Exelon)-slider-web — Clinton Nuclear Plant *Source: Exelon*

The appeal lent support to legislation that would shore up Exelon’s struggling Byron, Quad Cities and Clinton nuclear plants with $300 million per year that would be paid by Commonwealth Edison and Ameren ratepayers.

“One study found that world nuclear energy has prevented an average of 1.8 million premature deaths from fossil fuel pollution and could prevent up to 7 million additional ones in the future,” said the letter, posted on the site of Environmental Progress Illinois. The group was founded recently by Michael Shellenberger, a former anti-nuclear activist who now is an avid proponent. “Using the same methodology, Clinton and Quad [Cities] prevented 18,640 premature deaths from coal pollution,” it said.

The state’s nuclear plants are at risk, the letter continues, because they are excluded from state and federal clean energy subsidies that are available to wind and solar power. Wind and solar, which make up about 6% of the state’s generation, are intermittent and wouldn’t be able to replace the nuclear facilities, it said.

“One solution might be to expand Illinois’ renewable portfolio standard to include nuclear energy,” it said. “Such a change would allow Illinois to be more ambitious, achieving 70% or more of its electricity from clean energy.”

Among those signing the letter were climate scientist James Hansen, 1976 Nobel Prize winner in physics Burton Richter and Steve McCormick, former CEO of the Nature Conservancy.

Exelon supporters introduced the proposed Low Carbon Portfolio Standard in February 2015, and the company said it would close the three plants unless legislators acted before their summer break (HB3293, SB1585). When the bills languished, Exelon pulled back from the threat, saying, “We remain open to participating in any and all discussions designed to enact a legislative package.”

In late summer, Exelon nuclear units cleared capacity worth $1.6 billion in PJM’s first auctions under its new Capacity Performance model. Among the plants that cleared were Quad Cities, obligated to run through May 2018, and Byron, committed to run through May 2019. Following the auctions, CEO Chris Crane said the company would defer a decision about the plants’ closure for another year.

In November, Crane said that Quad Cities was breaking even, but on a fourth-quarter earnings call in February, he said that it was projected to drop back in the red as a result of low energy price forecasts. It and Clinton are still at risk of being closed, he said.

Exelon supporters introduced the portfolio standard on the heels of a dueling measure, the Clean Energy Jobs Bill (SB1485, HB2607). That bill, which is supported by environmental and consumer advocates and Chicago Mayor Rahm Emanuel, would benefit energy efficiency and wind and solar power.

Exelon’s ComEd also proposed legislation that contains initiatives the company said will “strengthen the security and resiliency of the grid, the construction of microgrids, community solar projects and the expansion of energy efficiency programs” (HB3328, SB1879).

There has been no action on any of the bills since October.

Asked last week about the status of its legislation, Exelon spokesman Paul Adams said, “Exelon, ComEd and [supporters of the Clean Energy Jobs bill] are in the midst of ongoing conversations to drive toward a comprehensive energy policy for the General Assembly to consider. Those conversations have been productive and have focused on common interests among the various groups toward an integrated low carbon energy future that fairly serves all customers, encourages economic growth and creates jobs.”

CEO Flexon: AEP Icing Dynegy out of Plant Sales

Dynegy CEO Robert Flexon says that American Electric Power is blocking companies that opposed its controversial power purchase agreement before the Public Utilities Commission of Ohio from bidding on power plants that AEP is trying to sell.

Flexon told Columbus Business First that Dynegy can’t get its foot in the door to bid on power plants that AEP is selling because Dynegy opposed AEP’s successful campaign to win regulatory approval for the PPA. “The funny thing there is AEP has specifically excluded anybody that dare speak against them in Ohio,” Flexon said.

PUCO recently allowed AEP’s distribution companies to enter into power purchase agreements with several of the company’s power plants, providing them with guaranteed income supported by ratepayers. AEP meanwhile is trying to sell several other plants not included in the PUCO ruling. AEP spokesperson Melissa McHenry said the company wouldn’t comment on plant sale details.

KCP&L to Purchase Power From 2 Missouri Wind Farms

Kansas City Power and Light announced it will purchase power from a pair of wind farms that are now under construction in northwest Missouri.

Under the 20-year deal, KCP&L will buy from NextEra Energy’s 200-MW Osborn wind farm, scheduled to be completed by the end of the year, and Tradewind Energy’s 300-MW Rock Creek wind farm, which is expected to be in service by September 2017.

Courtney Hughley, a spokesperson for KCP&L, said the goal is to use wind power and energy storage to eventually replace base load generation from coal-fired plants like Iatan in northwest Missouri.

US Rating Agencies Give LP&L Positive Reviews for Bonds

Lubbock Power & Light said last week it has received high bond ratings from all three major U.S. financial rating agencies, placing the municipal electric utility in a strong financial position as it moves forward with its transition to the regional grid.

If the utility ties into ERCOT, LP&L will issue bonds to pay for transmission lines needed to connect the city to the larger electrical system. The utility said its capital improvement projects will focus over the next three years primarily on getting its internal system ready to make the transition.

LP&L said Standard & Poor’s Rating Services gave it a “AA-” rating, Moody’s Investor Services assigned an “A1” rating and Fitch Ratings gave an “A+” rating.

CAISO Warns of Possible Summer Blackouts Because of Aliso Canyon

The inactive Southern California Gas Aliso Canyon underground gas storage facility this summer could cause energy shortages and imperil electric reliability, according to CAISO and other agencies.

The storage facility, which was shut down after leaking 100,000 metric tons of gas this winter, represents more than 64% of SoCalGas’ storage capacity, according to a report issued by CAISO, the Energy Commission, the Public Utilities Commission and the Los Angeles Department of Water and Power. The facility supplies fuel to 17 gas-fired power plants that account for about 70% of generation capacity in the region. It won’t be returned to service until later this year.

“Aliso Canyon plays an essential role in maintaining both natural gas and electric reliability in the greater Los Angeles area,” the agencies said in a statement. “As a result, the facility’s limited current operations create a distinct possibility of electricity service interruptions in the coming summer months.”

Temporary Wind Data Towers Now Require Visible Markings

A new state law will require visible markings on temporary meteorological towers used to gather data for wind energy projects, which critics say can be quickly erected and are difficult for low-flying pilots to see. The National Transportation Safety Board reports three fatal aircraft collisions with such towers since 2003.

As of May 30, any tower 50 feet or taller will be covered by the law. Previously, towers under the 200-foot federal threshold were exempt from a requirement for orange-and-white obstruction markings.

“We are very pleased the governor and Legislature passed this law quickly,” said Mike Trout, Aeronautics Commission director. The towers “can be very problematic for agricultural, balloon and helicopter pilots to see.”

Senate Considers Formula Ratemaking Bill

A utility-supported bill that would change how investor-owned electric utilities are regulated has advanced to the floor of the Senate for debate. The “21st Century Grid Modernization and Security Act” uses formula ratemaking and would weaken state utility regulators’ authority in rate-setting.

Ameren argues the bill would provide predictable rate increases that are needed to quickly recoup investments in the aging electric grid. Several large industrial customers oppose the bill, saying the new system will cause rates to rise beyond projections.

State Lawmakers Beat Filibuster, Advance Wind Energy Bill

State lawmakers have advanced a bill that will remove a requirement that wind energy developers need a power purchase agreement in place in order to serve out-of-state markets. Advocates say the measure will encourage more private development of wind farms that would otherwise go to other states.

Opponents tried to halt the proposal by arguing it would only help prop up an industry that relies on federal tax subsidies. But supporters said it would boost development that would generate tax revenue and lease payments for state residents.

The state ranks third nationally in the intensity of its winds, but lags most surrounding prairie states when it comes to installed wind-generating capacity. The proposal would liberate wind developers from having to arrange a power purchase agreement with out-of-state electricity buyers before getting approvals for wind projects aimed at serving regional markets.

Senate Leader Opposes Kinder Morgan Pipeline

Republican Senate President Chuck Morse is taking a stand against Kinder Morgan’s Northeast Energy Direct pipeline project, citing what he called the company’s dismissive attitude to the state’s regulatory authority.

“Given that there are pipeline projects being proposed in New England that provide similar benefits to New Hampshire with far less impacts, I believe that the NED pipeline, as currently proposed, is not the best project to address our current energy market problems,” he wrote in a recent letter to the chairman of the Public Utilities Commission and the state commissioner of environmental services.

Morse told the New Hampshire Union Leader his decision was prompted by Kinder Morgan’s letter to FERC reminding the agency that any restrictions imposed by the state would be pre-empted by federal law. The proposed pipeline would carry natural gas from Pennsylvania to New England, with an 80-mile route across the state.

Offshore Wind Farms Would Impact Beach Tourism, Study Says

A North Carolina State University economic study concludes that many tourists would be unwilling to rent beach houses if they included a view of offshore wind farms. The study from the NC State Center for Environmental and Resource Economic Policy also reports that tourists would expect to receive discounted rates if their viewshed included wind turbines.

“There was a lot of support for wind energy, but no one was willing to pay more to see wind turbines from the beach by their vacation rental property,” said Laura Taylor, the center’s director. “And if turbines are built close to shore, most people said they would choose a different vacation location where they wouldn’t have to see turbines.

“However, the good news is that our results also show that if turbines are built further than 8 miles from shore, the visual impacts diminish substantially for many survey respondents, and it is unlikely the turbines would negatively impact coastal vacation property markets,” she said.

Gov. Walker Lifts State’s Nuclear Ban

Gov. Scott Walker has signed 2015 Assembly Bill 384, revoking the state’s moratorium on new nuclear plants. The law orders the Public Service Commission to consider nuclear reactor construction before it can approve any new nonrenewable combustible-energy facilities.

The law revokes a 1983 state law, enacted four years after the Three Mile Island accident, which banned the state from considering new nuclear facilities until a national nuclear waste storage facility was constructed. There is still no waste repository, but nuclear advocates are renewing a push for atomic energy as a viable emission-free alternative to fossil fuel generation.

The state has one nuclear station, the Point Beach Nuclear Plant operated by NextEra Energy on Lake Michigan.

NYPSC: Minimal Cost to Meet 50% Renewable Goal

By William Opalka

New York consumers will see little change in their electric bills as the state switches to renewable energy resources at an accelerated pace, according to a study released by the Public Service Commission on Friday.

The Clean Energy Standard cost study puts a price tag on the state’s goal of generating 50% of its electricity from renewable resources by 2030.

“New York can meet its clean energy targets with less than a 1% impact on electricity bills (or less than $1 per month for the typical residential customer) in the near term and shows net positive benefit of $1.8 billion by 2023,” the study says. “… The current combination of low energy prices, low interest rates and available tax credits presents a uniquely favorable environment for near-term investment into renewables.”

The net benefit includes EPA’s “social cost of carbon” — an estimate of climate change damages, including changes in agricultural productivity, human health, property damages from increased flood risk and changes in energy system costs. It is projected at about $24/MWh in 2023.

The CES is part of New York’s Reforming the Energy Vision initiative to switch the state’s energy generation mix to cleaner and more distributed resources. It also promotes the preservation of upstate nuclear generation during a transitional period until 2030.

The cost study builds on a white paper released in January that outlined the policy goals (15-E-0302). (See New York Would Require Nuclear Power Mandate, Subsidy.)

PPAs vs. RECs

The study’s base case assumes power purchase agreements and renewable energy credits would be used equally to procure the 5.2 GW of Tier 1 renewables envisioned by 2023, which would be dominated by land-based wind (38%) and solar power developed under the NY-Sun initiative (52%). By minimizing investors’ exposure to commodity price risk, procuring capacity through PPAs would be far cheaper than procurement through RECs, the study said.

Changes in CES program costs as a result of energy prices would be balanced by the effect on ratepayers’ overall bills. “For example, lower-than-expected energy prices could increase the CES program costs, but this would be offset by a reduction in energy bills from lower wholesale energy prices,” the study says.

Nuclear Incentives

The New York CES is unique in that it promotes financial incentives to keep upstate nuclear power plants viable through 2030 to retain their carbon-free generation as the state transitions to renewable resources. (See related story, Environmental Group Urges Ill. Legislators to Save Nuclear Plants.)

“In addition to the cost and benefits quantified in this study, there are significant economic development benefits identified — for example, the proposal to provide new support for upstate nuclear plants would protect 25,000 direct and indirect jobs, $3 billion in direct and indirect economic activity and $145 million in state tax revenue,” according to the study.

Nuclear plants would be subsidized with a formula based on their costs of service. The study used a range of program costs — from $59 million to $658 million — based on low and high assumptions of the cost of generation of nuclear power and future energy prices.

Zero emission credits for nuclear plants will be based on an “open book” assessment of plants’ costs. Detailed cost estimates were not published in the study “to avoid prejudicing this process,” the study said.

The Upstate Energy Jobs Coalition of business, labor, economic development and other organizations reacted swiftly to the news.

“The state’s analysis confirms what most of us already know, which is that the costs of allowing upstate nuclear plants, with all of their economic and clean energy benefits, to close prematurely greatly outweigh the costs of implementing the CES,” said L. Michael Treadwell, CEO of the County of Oswego Industrial Development Agency. “The closure of FitzPatrick, Ginna and Nine Mile Point would be a severe blow to the economy upstate, a region that’s already struggling to turn its economy around.”

Entergy has said its James A. FitzPatrick plant would close despite state efforts to keep it operating. (See NYPSC OKs Ginna Deal.)

The special session will tack on about two hours quarterly to an SIS meeting, she said.

The task force was created under the SIS in December 2013 to improve the quality of synchrophasor data so that it could reliably be integrated into operational decision-making.

Since the group’s inception, the error rate of synchrophasor production data has shrunk from 14.35% to 2.45%.

PJM to Study Frequency Response for FERC Inquiry

PJM is conducting an internal analysis in response to FERC’s Feb. 18 notice of inquiry regarding frequency response, Eric Hsia told the committee. (See FERC Seeking Comments on Primary Frequency Response.)

The commission is seeking comment on whether new or existing resources should be required to have frequency response capabilities. It also wants to know the nature of frequency response compensation within the market optimization process.

PJM will present the results of its review at the May OC meeting.

Hsia said most resources that don’t provide frequency response are 10 MW or less and lack governors. Often these are distributed resources.

Operating Review Shows Perfect Dispatch Saved $33M YTD

A review of operating metrics showed that perfect dispatch has saved $33 million so far this year, with cumulative savings of $1.2 billion since the program was implemented in 2008.

Perfect dispatch, designed to measure how well PJM commits combustion turbines, is the hypothetical least production cost commitment and dispatch — what PJM would spend if it knew and could control all system conditions in advance.

The perfect dispatch rate this year through March was 83.92%.

The average load forecast error performance for March was 1.71%, within the goal of 3%. For the first quarter, all zones had errors below 3%, excluding East Kentucky Power Cooperative, which was above 4.5% (see chart).

The average forced outage rate through March was 3.48%, or 6,252 MW, with the total rate at 13.15%, or 24,743 MW.

PacifiCorp Offers Lessons for Future EIM Participants

By Robert Mullin

PORTLAND — PacifiCorp says future participants in the western Energy Imbalance Market (EIM) should benefit from early lessons the company learned in its efforts to integrate its real-time operations with CAISO.

The EIM got off to a rocky start in November 2014 as transmission constraints between California’s and PacifiCorp’s balancing areas produced price discrepancies that consistently required out-of-market mitigation measures. That issue was resolved by NV Energy’s entry into the market last December, which significantly improved transfer capacity among the regions.

During the first public meeting of the EIM Regional Issues Forum at Bonneville Power Administration offices Wednesday, PacifiCorp staff discussed the challenges and benefits of joining the EIM.

“The first thing I would say is PacifiCorp had the honor of doing this first,” said Sarah Edmonds, PacifiCorp Transmission vice president and general counsel. “Luckily, a lot of those bumps in the road have been addressed.”

A New Language

Edmonds said prospective EIM participants will first need to grasp a new lexicon. “The EIM and the ISO have a whole new set of acronyms that you have to know,” she said.

The second piece of advice: Look at your maps.

“The West is very special,” Edmonds said. “It has all kinds of special arrangements that are grandfathered in. Go talk to your neighboring balancing areas.”

Stuart Kelly, PacifiCorp vice president of major project delivery, said one of the biggest challenges concerned what data to exchange with CAISO, especially data that relate to market settlements.

“Not just the output [to CAISO], but the input back into your system,” he said. Kelly encouraged participants to meet with CAISO staff early in the integration process to learn how the ISO settles transactions.

“I think most operations are not set up to handle the rapidity [of the EIM] and the settlement process,” Edmonds added, noting that dispute rights over energy transactions have time limits. For that reason, an EIM participant must streamline its procedure for generating “shadow settlements” — the participant’s own payout estimates from a transaction — which can differ from those ultimately provided by the ISO.

The settlement process affects not only an EIM members such as PacifiCorp but also non-affiliated utilities within an EIM balancing area that must rely on PacifiCorp to facilitate their EIM transactions. Clay MacArthur, assistant vice president of power marketing and contracts for Deseret Power, said settlement delays have caused problems for his Utah-based electric co-op.

“When you go into nine months and longer [for some settlement data], some of the market signals you thought you would get, you don’t get on a timely basis,” MacArthur said. He added that settlement statements from PacifiCorp at times provide either too much or too little data, requiring the utility to “reverse engineer” the documents to determine what they mean.

“We recognize there are improvements to be made in our settlements,” Edmonds said.

Better Visibility, More Discipline

Joining the EIM also presents new challenges for physical operations.

Describing his company as “a little bit of a problem child” because it operates two balancing areas, PacifiCorp’s Kelly stressed that EIM participants must ensure their network models can be exported to CAISO to facilitate integrated operation.

“If you’ve got [variable energy resources] in your portfolio, you have to get a handle on your forecast,” he said. “The challenge will be predicting when you have some kind of ramp.” Kelly said CAISO’s forecasting model was better than what PacifiCorp had previously relied upon.

Kelly also described outage management under the EIM as “a whole new language” that his company had to get right in order to coordinate schedules with the ISO. He pointed out CAISO’s requirement that it be notified of any system upgrades three months in advance.

“What the EIM requires is a level of discipline in those areas that you have never experienced,” Edmonds said.

That discipline appears to be spilling into neighboring Northwest balancing areas, whose system operators must coordinate with EIM participants.

“I think the implementation issues are getting simpler,” said Russ Mantifel of BPA’s transmission and policy group. “Right now I think we’ve now proved a concept to use EIM to move megawatts that can be scaled up. I think there’s increased visibility and control.”

Edmonds called visibility into neighboring balancing areas “one of the iterative, evolving parts of the EIM.”

Bidirectional Learning

Lessons from the EIM have not been a one-way street, according to forum participants.

“On the other side of the equation, the ISO is learning its own form of Western multiculturalism,” Edmonds said, noting that CAISO must deal with the capabilities of other areas while maintaining its own balancing area. “There’s a bilateral need to understand each other and each other’s lexicons.”

“A lot of these matters are very complex,” said energy consultant Tony Braun, an EIM Transitional Committee member. “You can’t know how complex until you’re in them.”

Despite the complexity, Kelly said PacifiCorp recovered its integration costs within the first year of operation because of the increased efficiency of the market.

“After seeing the benefits, I would encourage others to join,” he said. He also pointed to what he called NV Energy’s “seamless” integration into the market late last year. (See NV Energy has Smooth EIM Integration, CAISO Says.)

“We could not have gotten there as easily as we did — and it was not easy — if not for PacifiCorp having problem-solved a year before,” NV Energy attorney Lauren Rosenblatt said.

Artificial Island Cost Increase Could Lead to Rebid

By Suzanne Herel

VALLEY FORGE, Pa. — PJM planners are rethinking a piece of the Artificial Island project, a move that could alter its scope and possibly require the RTO to solicit new bids under FERC Order 1000.

Salem-Nuclear-Generating-Station-on-Artificial-Island-(Wikimedia)-for-slider, ferc order 1000 — Salem Nuclear Generating Station on Artificial Island

The move comes after Public Service Electric and Gas submitted estimates that nearly doubled the cost of its section of the stability fix from $137 million to $272 million. (See Cost Estimate of PSE&G Portion of Artificial Island Fix Doubles to $272M.)

“We are looking at options to mitigate the cost,” Steve Herling, PJM vice president of planning, told the Transmission Expansion Advisory Committee on Thursday.

PJM has been working with PSE&G and consultants to analyze the cost estimates and design, and their work is nearly done, said Paul McGlynn, PJM general manager of system planning.

The project involves building a 230-kV transmission line from the New Jersey complex housing the Hope Creek and Salem nuclear reactors under the Delaware River to Delaware. Calls for proposals went out three years ago.

After a long, contentious process, LS Power won the job of building the line, largely because of its promise to cap construction costs at $146 million.

LS Power: ‘Nothing Has Changed’

“From LS Power’s standpoint, we’re committed to working with PJM and looking at these alternatives,” Vice President Sharon Segner told the committee. “Our cost cap remains the same. Nothing has changed.”

PSE&G was assigned the tasks of expanding the Salem substation and building a static VAR compensator (SVC) at New Freedom. PSE&G’s work is considered an upgrade and does not include a cost commitment.

Pepco Holdings Inc. was tapped to oversee interconnecting the new substation to the existing Red Lion-Cartanza and Red Lion-Cedar Creek 230-kV lines in Delaware. (See PJM Staff Picks LS Power for Artificial Island Stability Fix; Dominion Loses Out.)

Herling said planners now are considering a new configuration that would terminate the transmission facility at Hope Creek instead of Salem. The buildings abut each other, and Hope Creek would give contractors more room to work, Herling said. However, unlike Salem, it is not on the water, where the horizontal directional drilling to bring in the line would end.

Overhead construction is not an option because of existing 500-kV lines, he said, so the line would have to be buried. But the drilling is not precise; it would have to be done in a wide sweep around the Salem substation, Herling said, or vaults would have to be built.

Timeline at Risk

Any significant change to the plan will affect the timeline, he said. “It could take another year, putting the system at risk,” he said.

There’s also the chance that altering the configuration would end up being just as expensive or simply move the cost from PSE&G’s end over to LS Power’s portion. Expense will have to be weighed with constructability and risk, Herling said.

“Clearly, this is a change in scope for LS Power and PSE&G,” Herling said. “We’re still looking at process implications.”

In an interview, Herling said if that change in scope is challenged, FERC could rule that the project needs to be rebid.

PJM will be reviewing the project with the Board of Managers, which meets next week, but will not be making a recommendation.

“The board may give us more things to go look at,” he said. “We will be working this as quickly as we possibly can to have the board make a decision.”

The project has been controversial not only among the companies that vied for the contracts, but as well as with regulators and consumer advocates in Delaware and Maryland, where most of the cost would be assigned.

In response to complaints, FERC suspended the project’s cost allocation pending additional review, which included a technical conference in January (EL15-95). (See Commenters: DFAX Cost Allocation Inappropriate.)

Eversource CEO Retiring; CFO Named Replacement

By William Opalka

Eversource Energy CEO Tom May will retire in a month and be replaced by current CFO Jim Judge, the company announced Wednesday.

May, 68, will become board chairman after the company’s annual shareholders meeting May 4 in Boston. Under the succession plan, Judge will join the board next month and become chairman at Eversource’s annual meeting in 2017.

James J Judge Eversource Energy 2016 — Judge

May and Judge have worked together for 38 years. For the past 22 years, before and during a series of mergers, May has been CEO of Boston Edison, NSTAR and Northeast Utilities, which was renamed Eversource Energy in 2015. (See Northeast Utilities Rebranding as Eversource Energy.)

NSTAR and Northeast Utilities merged in 2012 to create an electric and gas utility company in Connecticut, Massachusetts and New Hampshire with 3.6 million customers and a market capitalization of $18 billion. The company has joint headquarters in Boston and Hartford.

“Tom May has been an extraordinary leader for more than two decades as chief executive. He has delivered superior results in every category — customer, financial, operations, safety and community,” Sanford Cloud, lead trustee of the board, said in a statement.

Judge will remain in his role as Eversource CFO until a successor is named.

Besides pursuing growth and acquisitions, May has become known for forging partnerships with developers to propose controversial projects that would bring fuel resources into New England.

In 2008, NSTAR and Northeast Utilities formed a joint venture, Northern Pass Transmission, to import Canadian hydropower supplied by Hydro-Quebec through New Hampshire. That project, vehemently opposed by some environmentalists and natural gas generators, is currently undergoing site evaluation by state officials. (See Committee Rules Northern Pass Application Complete.)

Eversource also has a 40% stake in the proposed $3 billion Access Northeast natural gas pipeline with partners Spectra Energy and National Grid. The pipeline would run through New York, Connecticut, Rhode Island and Massachusetts. (See Algonquin Submits Pre-Filing Request for Access Northeast Pipeline.)

Pipeline plans have generated controversy as some state regulators have endorsed a regional plan to have funding come from electricity customers. (See Massachusetts Regulators Endorse Pipeline Contracts.)

Dominion: Tx Project Should be Regionally Allocated

By Suzanne Herel

Dominion Resources is asking FERC to rehear two related February decisions in which the commission reversed a previous order and ruled that transmission projects that solely address a transmission owner’s local planning criteria are not eligible for regional cost allocation (ER15-1387).

In its first application of the rule, FERC said Dominion was solely responsible for the cost of its $160 million, 500-kV Cunningham-Elmont rebuild (ER15-1344). (See FERC Does 180 on Local Tx Cost Allocation in PJM.)

Dominion also has filed a protest of PJM’s compliance filing, which FERC required in its February determination.

The company requested that FERC rule on the rehearing request at the same time it decides on PJM’s compliance filing.

Also asking for rehearing are Old Dominion Electric Cooperative, LSP Transmission Holdings and ITC Mid-Atlantic Development.

Meanwhile, PJM requested a clarification on how it should apply the new methodology to certain projects in its Regional Transmission Expansion Plan.

In its rehearing request, Dominion argued that its proposal has regional benefits and is unlike 98% of Form 715 projects whose costs are designated to the local TO because they deliver only local benefits.

“The other 2% have had their costs allocated at least 50% regionally because they belong to a cost allocation class previously determined to have regional benefits,” it said. “Nothing about the 98% statistic explains why such projects no longer have regional benefits.”
