CAISO Tariff Change Would Extend Market to DER

By Robert Mullin

CAISO has asked FERC to approve a new Tariff provision that would enable rooftop solar and other small distributed energy resources (DER) to participate in California’s energy and ancillary services markets (ER16-1085).

The rule changes create an “initial framework” to extend market participation to DER smaller than 0.5 MW — the current minimum for selling into the ISO’s wholesale market — by allowing for aggregation at the distribution system level.

CAISO is anticipating participation by distributed generation, energy storage and electric vehicle charging stations, but the framework leaves open the possibility for market entry by other types of resources located on either side of the customer meter. This “broad definition” of eligibility is intended to avoid excluding emerging technologies from participating in aggregation.

“The framework will accommodate various resource types as well as different business models, provided the aggregation is capable of operating as an integrated resource and meets specific technical requirements,” CAISO wrote. Those models could include microgrids interconnected to distribution systems as well as third-party aggregators and utilities operating DER.

The rules would bar some resources from participating in aggregations, including generation rated at 1 MW or greater, demand-side resources bid into the market by curtailment service providers and demand response intended to react to grid emergencies. Generating units between 0.5 MW and 1 MW would need to terminate their participating generator agreements in order to join an aggregation. Also excluded would be resources already participating in a retail net energy metering program.

New Participant Type

The Tariff revisions would introduce three new terms into CAISO’s official market lexicon:

Distributed energy resources: Any resource in the ISO balancing area with a first point of interconnection to a utility distribution company or a metered subsystem.
Distributed energy resource aggregation: A “market resource” comprising one or more DER organized to participate in the wholesale market. Aggregations can contain multiple resource types, but resources will be restricted to participating in a single aggregation.
Distributed energy resource provider: “A new type of market participant,” according to CAISO, DER providers would be owners or operators of an aggregation. They would engage the market through a registered scheduling coordinator, which would submit schedules and bids based on the aggregation’s generation distribution factors.

The rules would permit a DER aggregation to operate at a single pricing node or across multiple nodes. Regardless of the configuration, the resources are required to provide a net response at the nodal level consistent with dispatch instructions, with missteps subject to imbalance charges.

Compensation will be based on nodal LMPs, but CAISO will not directly poll meters in an aggregation, so DER scheduling coordinators must provide the ISO with settlement quality meter data in order to receive payments.

In its filing with FERC, CAISO urges approval of the changes by pointing out that distributed facilities already participate in ISO wholesale markets as both generating and demand-side resources.

“The Tariff revisions proposed in this filing do not change those arrangements,” CAISO wrote. “Instead, the CAISO is extending the same opportunity to support the reliable operation of the transmission system to aggregations of distribution-connected resources, recognizing the significant transformation in the industry and deployment of emerging technologies.”

CT Power and Energy Society’s Annual Energy, Environment and Development Conference

Connecticut sees itself as an energy technology and policy innovator, but much work remains to help it maintain its leadership position, speakers said at the annual Connecticut Power and Energy Society’s Energy, Environment and Development Conference last week.

CT Gov Dan Malloy — Dan Malloy *© RTO Insider*

Connecticut Gov. Dannel Malloy said he is looking forward to the Clean Power Plan, which he believes will be upheld in the courts. “In Connecticut and New England, what these rules are saying is ‘finally, the rest of the country is going to have to live by the same set of rules that we’ve had to live by,’” he said.

New England has long complained of being at the ‘end of the tailpipe’ from Midwest polluters. Malloy said the CPP will be good for his state’s environment — and its economy. “I think it will level the playing field, at least with respect with our ability to compete with other states [and] with respect to the cost of the eventual product, electric energy.”

David Kooris, director of the City of Bridgeport’s office of planning and economic development, recounted the difficulties the city had winning state and federal regulatory approval for a 1.6-MW anaerobic digester and cogeneration facility built near a wastewater treatment plant. “The regulatory environment isn’t yet ready to accommodate some of the new technologies we’re talking about. That was a tough regulatory process and [state environmental regulators] were working closely with us, knowing it was an objective of theirs. But it was fairly arduous just because of the outdated aspects of the regulations.”

Daniel Sosland, Acadia Center — Daniel Sosland *© RTO Insider*

Daniel Sosland, president of the Acadia Center, said technology is creating a historic transition in the electric industry. “The question is how fast will we get there. Will markets drive changes? Will policy keep up?” he asked. “The system that we’ve built and has been reliable is a one-way power flow … but in the system we’re building now, the centerpiece is in your community. It’s in your home, it’s in your place of work.”

Jonathan Milley © RTO Insider — Jonathan Milley *© RTO Insider*

Jonathan Milley is director of business development for Vionx Energy, which is developing flow battery technology that proponents say will deliver long-duration energy storage at lower costs than lithium-ion batteries. He talked about storage’s challenges in winning a place in the market. “Storage is trying to find a leg in the three-legged stool in between generation, transmission and distribution, and doesn’t quite know how to fit into the equation.”

Katie Scharf-Dykes © RTO Insider — Katie Scharf-Dykes *© RTO Insider*

Katie Scharf Dykes, the Connecticut Department of Energy and Environmental Protection’s deputy commissioner for energy, spoke of accommodating state public policy goals in deregulated wholesale energy markets. “I hope there’s a peaceful resolution, a productive resolution,” she said. “State public policy goals are not discretionary whims; we have a statutory mandate to cut carbon, and we have an obligation to our ratepayers and our children to address this challenge.”

Paul Hibbard © RTO Insider — Paul Hibbard *© RTO Insider*

Paul Hibbard, vice president of The Analysis Group, said resolving cost allocation questions is essential to overcoming the region’s infrastructure challenges. “The real confusing piece is what consumers will pay for which pieces of infrastructure, how much will that cost and what might be the alternatives.”

State-Sponsored Energy Procurement Moves Ahead in NE

By William Opalka

CROMWELL, Conn. — Requests for proposals for the next rounds of multistate clean energy, efficiency and storage procurement were released on Wednesday.

The RFPs were for resources from 2 to 20 MW as well as energy efficiency and energy storage, according to Connecticut Department of Energy and Environmental Protection Deputy Commissioner for Energy Katie Scharf Dykes.

“It’s clear the transformation in the energy market and the electricity market is really accelerating,” she told the Connecticut Power and Energy Society’s annual Energy, Environment and Development Conference.

In addition to the multistate procurement, DEEP also issued a draft RFP for natural gas resources. The procurements were authorized by the state’s Affordable and Reliable Energy law, passed last year.

Connecticut, Massachusetts and Rhode Island last year released an RFP for large-scale renewable energy projects, reasoning that joint proposals and larger projects would obtain lower costs than states could secure on their own. (See New England States Combine on Clean Energy Procurement.)

The selection of successful bidders will begin in late April.

Eversource Energy President of Transmission Jim Muntz said the RFP for large-scale projects provided a glimpse of how market participants would respond to multiple jurisdictions.

“This was really the first real opportunity for folks to put some reality to their idea and try to marry up with the customers who stated a willingness to pay,” he said. “This is somewhat rare to have that in the neighborhood of a big idea.”

Among the proposals is Eversource’s Northern Pass transmission line, which would carry Canadian hydropower into the region.
In total, about 4,200 MW were proposed. But “big ideas” like undersea transmission lines from Canada or large offshore wind projects were noticeably absent.

Although several projects proposed large-scale wind and transmission in Maine, none were paired with any proposals that would build transmission to move energy farther south. Except for relatively small improvements along the New York-New England interface, no solutions were offered to relieve many of the existing choke points.

Coal-fired plants represented more than 80% of the 18 GW in generation retired in 2015, according to the U.S. Energy Information Administration.

The plants that retired were mostly built between 1950 and 1970, and the average capacity was 133 MW, compared to an average 278 MW of capacity for the coal-fired fleet still in operation. Nearly half of the retired coal capacity was in Ohio, Georgia and Kentucky.

About 30% of the plants that shut down in 2015 went cold in April, when EPA’s Mercury and Air Toxics Standards went into effect. A number of plants received a one-year extension, and they are expected to retire next month.

EPA Expanding Methane Crackdown to Existing Wells

epa

EPA announced it will require existing oil and natural gas wells to abide by tougher methane-emission regulations already covering new wells.

The announcement came during President Obama’s meeting with Canadian Prime Minister Justin Trudeau. EPA Administrator Gina McCarthy said the expansion of the rules was necessary if the U.S. was to reach its goal of cutting emissions by 40% by 2025. “Based on this growing body of science, it’s become clear it’s come time for EPA to take additional action,” she said.

The oil and natural gas industry reacted negatively. “The administration is catering to environmental extremists at the expense of American consumers,” said Kyle Isakower of the American Petroleum Institute.

Solar Market Set to Grow 119% This Year

The U.S. solar generation market is set to increase 119% this year, mostly from utility-scale projects in the pipeline, according to GTM Research in its U.S. Solar Market Insight Year in Review, published in conjunction with the Solar Energy Industries Association.

The forecasted surge of 16 GW of solar that will be installed in 2016 was caused by the expected expiration of federal tax credits in 2016. The tax credit was extended, but not before investors committed their 2016 budgets to some big projects. Utility-scale installations are expected to decline in 2017.

The report said new community solar projects are also growing, and rooftop solar continues to drive solar demand.

Jury Taps Shale Driller for $4.2M in Tainted Water Suit

A U.S. District Court jury in Scranton, Pa., hit Cabot Oil & Gas with a $4.2 million verdict, saying the company’s gas-drilling operations contaminated the well water of two Pennsylvania families.

The families in the Susquehanna County town of Dimock alleged that their water was contaminated by methane after Cabot began drilling in the area. Cabot argued that the methane occurred naturally and was not caused by the company’s action. It vowed to appeal the verdict.

NRC Annual Assessment Shows 96 of 99 Plants in Top 2 Categories

The Nuclear Regulatory Commission released its annual assessment of nuclear power plant operations for 2015, and all but three units were graded in the two highest categories. Of the 96 highest-performing reactors, 85 fully met all safety and security objectives, the commission said.

Arkansas Nuclear One Units 1 and 2 and the Pilgrim plant in Massachusetts were ranked in the fourth category and will receive increased oversight. The Arkansas units landed in the category because of two significant safety findings during inspections, and Pilgrim because of “long-standing issues of low to moderate safety significance,” according to an NRC news release.

Entergy owns both the Arkansas and Pilgrim plants.

US Nuclear Fleet Safer After Fukushima, NRC Says

Nuclear Regulatory Commission Chairman Stephen Burns said that changes the agency instituted after the earthquake-induced meltdown of Japan’s Fukushima Daiichi plant have made the U.S. fleet safer.

“I think the plants are safer than they were five years ago,” Burns told Bloomberg BNA. “A lot of the things we’ve done, I believe, have made a safe situation safer.”

The changes, such as second sets of backup generation, batteries and pumps, addressed failures exposed at Fukushima, said Tony Pietrangelo, senior vice president and chief nuclear officer of the Nuclear Energy Institute. “When you boil it down to its basic, root causes, they lost electricity and they lost the ability to cool the [reactor] core, to maintain the containment integrity and to cool the spent fuel,” he said.

Fire Prompts ‘Unusual Event’ at Watts Bar 2

A pump motor serving the reactor at the Watts Bar 2 nuclear station caught fire, forcing a declared “unusual event” before the Tennessee Valley Authority’s newest station produced any power.

The small fire Wednesday in one of three hot-well pump motors was extinguished within 19 minutes, but the incident required TVA to declare a “Notice of an Unusual Event.”

“Plant personnel extinguished the motor fire, and there was no danger to the public,” TVA spokesman Jim Hopson said. “Other Watts Bar Unit 2 systems were unaffected. Watts Bar Unit 1 was also unaffected and remained safely online throughout the event.”

Studies Show Undersea Cables Don’t Repel Marine Creatures

A trio of recent studies show that magnetic fields emitted by undersea transmission cables don’t seem to harm marine wildlife, a finding that could boost the development of offshore wind energy.

Earlier generations of cables, including undersea telecommunication cables, attracted wildlife such as sharks, which sometimes bit into the cables. Insulating the cables caused the sharks to lose interest, but magnetic radiation prompted some researchers to wonder if the cables served as “electric fences.”

The recent research suggests the magnetic fields don’t affect marine life. “There’s much less concern now,” said Ann Bull, a marine biologist at the Bureau of Ocean Energy Management, who presented two of the studies at the American Geophysical Union’s Ocean Sciences Meeting. Her experiments showed that even where magnetic fields were strongest, creatures such as crabs did not seem bothered.

Bowring Urges Return to ‘Fundamentals’

By Michael Brooks

WASHINGTON — PJM needs to return to “the fundamentals” with market design not “influenced by political whims,” Independent Market Monitor Joe Bowring said last week.

Policymakers should not fear market prices going too high or low, Bowring said in a press conference announcing the Monitor’s annual State of the Market report.

“There’s a million temptations to move away from the basics because somebody might be getting hurt by them,” he said, noting that every sector of the market complains about the rules sometimes. “That’s all good because it’s not supposed to be helping any particular sector; it’s supposed to be reflecting the value of power.”

As in past years, the Monitor found that PJM’s energy, capacity, regulation, synchronized reserve and financial transmission rights markets were all competitive in 2015, as mitigation overcame market power found in all but the FTR market. The Monitor judged the design of the regulation and FTR markets as “flawed” and that of the capacity, day-ahead scheduling reserve and synchronized reserve markets “mixed.”

The Monitor listed 27 new recommendations, 10 of them high priority, for 2015. (See New, High-Priority Recommendations – 2015 State of the Market Report below.) Half of the high priority recommendations relate to the FTR market. (Ten of the new recommendations were listed in prior quarterly reports.)

It also for the first time compiled a list of all recommendations it has made since 1999, listing their status and priority. The report shows that PJM has fully adopted 24% of the Monitor’s recommendations, including 36% of those identified as high priority.

Energy Market

Abundant, cheap natural gas drove down LMPs in 2015, a sign that the energy market is both competitive and effective, Bowring said. “When you have a competitive market, the price of inputs flow through,” he said. “Both price inputs went down — the price of gas primarily — and also load went down. The result is a very immediate decline in prices.”

The average real-time LMP dropped to $36.16 from $53.14 in 2014, when the demand for gas during the January polar vortex resulted in a price spike. Using 2014’s fuel prices, LMPs would have been $41.91, or % higher. Prices were the second lowest since 2002, above only 2012.

Although energy market results generally reflected supply-demand fundamentals, “the behavior of some participants during high demand periods is consistent with economic withholding,” the Monitor said.

Among the new is that PJM define rules for using transmission penalty factors to set LMPs when a transmission constraint is binding and there are no generation alternatives to resolve it.

When system operators allow the limit to be violated, the shadow price of the constraint is administratively set through transmission penalty factors, a form of locational scarcity pricing. Bowring said that there is nothing wrong with PJM doing this, but there are no rules for it in the RTO’s governing documents.

Capacity Market

One of the challenges with this year’s report on the capacity market, Bowring said, was the introduction of Capacity Performance. “The Capacity Performance design incorporated a lot of the recommendations we’ve been making over the last five years, and we think it’s a huge improvement,” he said. “But nonetheless the design that was in place in 2015 was the old design and with all of its flaws. … Going forward, the design has been substantially improved.”

Despite the improvements, Bowring said more needs to be done. For example, PJM’s method for calculating units’ net revenue to determine net cost of new entry “is just wrong,” he said. The Monitor recommends that net revenue reflect the actual flexibility of units to respond to price signals. Bowring also warned against efforts by some stakeholders to dilute the penalties for nonperformance under the new market structure. (See PJM Generator Risk Proposal Faces Resistance.)

Fuel Mix

Coal declined sharply in 2015, from 72.4 GW of installed capacity on Jan. 1 to 66.7 GW on Dec. 31, making up 37.5% of total capacity. Gas, meanwhile, rose to 60.4 GW, or 34%, by the end of the year. The Monitor expects gas to overtake coal as the dominant resource in PJM this year, according to the report.

Net revenue for new entrant combustion turbines and combined cycle units was more than enough to recover CONE in most zones, while “if you built a new coal plant you would recover, at most, about a third of your total investment,” Bowring said. Nuclear plants did not have it much better. “No rational investor would build either a coal unit or a nuclear unit now in PJM given the recovery of their costs.”

Still, Bowring doesn’t expect coal to disappear completely from PJM, even if EPA’s Clean Power Plan survives legal challenges, because regional carbon trading will allow states to comply without huge coal retirements. The volatility in gas prices means that coal plants that have installed environmentally compliant technology can still make money. “I expect coal to be a very substantial part of PJM for the foreseeable future,” he said.

Renewable resources are doing very well because of federal tax credits and state incentives, Bowring said, with solar recovering 175% of its 20-year costs in the PSEG zone.

Demand Response

The Monitor repeated its recommendation, first made in 2014, that demand response be removed from the supply side of PJM markets. While DR is a key part of the wholesale power markets, it should be moved to the demand side and customers and curtailment service providers should have more granular data so that they can respond better to price signals, according to the report. “The method of incorporating it in the PJM market design … simply doesn’t work and is very inefficient,” Bowring said.

Bowring admitted that this was unlikely to happen — but not because of the U.S. Supreme Court’s decision upholding FERC’s jurisdiction over DR. “The Supreme Court decision was actually a good thing because it got rid of all the uncertainty,” he said. “No one was doing anything about DR because they were so uncertain. Uncertainty’s gone. FERC has authority. Fine, that’s great.

“But the Supreme Court did not order them to pay LMP, and not LMP minus G” — the retail price of power — Bowring said, “because the Supreme Court doesn’t know the difference between those two things.”

New, High-Priority Recommendations – 2015 State of the Market Report

Energy Market

To ensure effective market power mitigation when the three pivotal supplier test is failed:

Markup should be constant across price and cost offers, and there should be at least one cost-based offer using the same fuel as the available price-based offer; and
The operating parameters in the cost-based offer and the price-based parameter limited schedule (PLS) offer should be at least as flexible as the operating parameters in the available non-PLS price-based offer. The price-MW pairs in the price-based PLS offer should be exactly equal to the price-based non-PLS offer.

Demand Response

PJM should require nodal dispatch of demand resources with no advance notice or, if nodal location is not required, subzonal dispatch of demand resources with no advance notice.
PJM should eliminate the measurement of compliance across zones within a compliance aggregation area. The multiple-zone approach is less locational than the zonal and subzonal approach and creates larger mismatches between the locational need for the resources and the actual response.

Interchange Transactions

PJM Settlement Inc. should immediately request a credit evaluation from all companies that engaged in up-to-congestion transactions (UTC) between Sept. 8, 2014, and Dec. 31, 2015. If PJM has the authority, PJM should ensure that the potential exposure to uplift for that period be included as a contingency in the companies’ calculations for credit levels and collateral requirements. If PJM does not have the authority to take such steps, PJM should request guidance from FERC. (PJM traders are awaiting a FERC order telling them whether UTC trades will be charged uplift and made subject to the RTO’s financial transmission rights forfeiture rule (EL14-37). FERC had indicated it would rule by last October, but there has been no word from the commission so far. See FERC Issues Request for Comments in UTC Uplift Docket; Ruling by October?)

Financial Transmission Rights

The design of FTRs and auction revenue rights should be modified to ensure that all congestion revenues are returned to load.
All FTR auction revenue should be distributed to ARR holders.
Historical generation-load paths should be eliminated as a basis for allocating ARRs.
Counterflow FTRs should be eliminated.
FTR auction revenues should not be used to buy counterflow FTRs with the purpose of improving FTR payout ratios.

Agencies Suspend Work on State CPP Compliance

The Department of Environmental Quality and the Public Service Commission announced they are halting an effort to draft a compliance plan for EPA’s Clean Power Plan as a result of last month’s U.S. Supreme Court decision to stay its implementation.

The PSC’s executive director, John Bethel, said discussions surrounding the rule’s potential implementation should carry on, however. “The stakeholder process will continue to evaluate what steps will be necessary to comply with the plan should it be upheld. Those activities might proceed on a modified timeline once we understand more what that might be.”

The state agencies said they will “continue to follow modeling efforts by the private sector of potential future energy and environmental policy scenarios.” They plan to have a technical session on energy sector modeling later this year.

It Isn’t Easy Being Green, Commission Says

The Commerce Commission has proposed tightening the rules for retail electric suppliers to market their power as “green.”

Unless a customer’s residence is directly connected to a wind farm or solar panels, the electricity flowing to it cannot be said to be generated by renewable resources, Attorney General Lisa Madigan, who supports the changes, told the commission.

The claim of green energy generally comes from the purchase of renewable energy credits, as all the electricity on the grid is intermingled, regardless of its source, Madigan said.

In a March 3 ruling, Judge Mike Menahan upheld the PSC’s decision to maintain existing “standard rates” for certain wind and solar projects no larger than 3 MW. The Public Utility Regulatory Policies Act requires NorthWestern to purchase power from these qualifying facilities based on the utility’s avoided cost, PSC officials said.

Bill Removing Restriction on Wind Development Stalled

Legislation that would make it easier for wind developers to advance projects in the state appears to be stalled in committee, although an effort is underway to advance the bill to a floor debate through extraordinary measures.

LB824 would remove all restrictions on developing wind energy, according to state Sen. Dan Hughes, who worries that a proliferation of wind energy would ultimately increase power rates. The legislation received the Natural Resources Committee priority designation in February but is now stuck in committee on a 4-4 vote, according to Hughes.

Hughes said it was important to realize that utilities need to also provide backup power for when the wind isn’t blowing, adding to the projects’ cost. “If we currently have excess power generation, I see no reason to build,” he said.

Environmental Group Asks Energy Contracts Be Kept Public

An environmental group is asking the Public Regulation Commission not to impose confidentiality rules that would restrict public access to a coal supply contract, financial information for an Arizona nuclear power plant and other documents that are part of Public Service Company of New Mexico’s request to raise electricity rates.

Western Resource Advocates says information that affects rates charged by the utility should be open to the public. PNM is asking the commission for approval to raise residential rates by 15.8%, increasing annual revenue by about $123.5 million.

The utility said disclosing pricing information would hurt its ability to negotiate the best prices for goods and services. PNM used the same argument last year to maintain confidentiality over a coal supply agreement for the San Juan Generating Station. The PRC accidentally broke the confidentiality agreement when it disclosed the coal supply agreement and other confidential documents in response to a newspaper’s public records request.

Farmington-Bloomfield Utility Case Dates Back to 1960s

Farmington and Bloomfield officials have until March 17 to decide how they will proceed with a legal dispute between them after a judge said a 1960s electric utility municipalization case could be reopened.

Bloomfield argues that under the 1960 agreement in which Farmington acquired its electric system from a private owner, Bloomfield also had the rights to municipalize the power system within its city limits. Farmington had argued that Bloomfield’s rights to infrastructure within its boundaries expired in 1974 under the statute of limitations.

Xcel Customers to Receive More Refunds

Xcel Energy ratepayers will receive a one-time credit — $3 for residential customers — in a $702,656 refund granted because of a settlement over the federal government’s failure to acquire a long-term storage site for spent nuclear fuel.

The Public Service Commission approved Xcel’s request last week to distribute the customer refunds on behalf of its Monticello and Prairie Island nuclear power plants. Commission Chair Julie Fedorchak said 30% of the electricity used by Xcel’s 90,000 customers in the state comes from nuclear sources.

Under the Nuclear Waste Policy Act of 1982, utilities executed contracts with the U.S. Department of Energy for the storage of spent nuclear fuel, but the department never secured a site. Xcel and other utilities sued the department, and the parties settled in 2011.

Proposed NextEra Wind Farm Hits Court Snag

NextEra Energy is facing challenges to get approval for its proposed 87-turbine wind farm in Stark County. A first proposal was rejected last year, while a new version of the project with adjusted siting is currently stalled in a court dispute.

An opposition group, Concerned Citizens of Stark County, claims in a lawsuit that the county zoning board and county commission circumvented proper public notice when it held meetings within a day of each other in December to approve the proposal. Because the suit is unresolved, the Public Service Commission announced that it would delay its public hearing until March 30, giving the citizens’ group more time to review submittals from NextEra.

Some residents are urging NextEra to construct the turbines 2,000 feet from property lines instead of the proposed 2,000 feet from residences.

Operators of New Gas Plant Against AEP, FirstEnergy PPAs

The operators of the newest power plant in the state have said they may take legal action if the Public Utilities Commission approves a guaranteed income plan for power producers FirstEnergy and AEP Ohio.

Oregon Clean Energy, which has nearly completed construction of an 860-MW natural gas plant in the town of Oregon, says the eight-year power purchase agreements proposed by FirstEnergy and AEP would give them an unfair advantage. FirstEnergy and AEP say they need the PPAs to keep their coal-fired and nuclear plants operating and to preserve system diversity and reliability.

Merchant power producers say they will continue to fight if PUCO rules against them. “We could very easily see a scenario where utilities go to the General Assembly to look for a solution,” said Dylan Borchers, an attorney for Oregon Clean Energy, which is owned by Ares Management LP and I Squared Capital.

SPP, MISO Declare Year 1 of M2M a Success

By Tom Kleckner

LITTLE ROCK, Ark. — SPP and MISO staff told stakeholders last week that the market-to-market process across their seam worked well in its first year and that a memorandum of understanding between the two RTOs will solve most remaining problems.

In a meeting at SPP’s headquarters Tuesday, staff said that the process has worked as intended since it began in March 2015. M2M is designed to improve price convergence on flowgates along the RTOs’ 1,200-mile seam. They compensate each other for re-dispatching generation to reduce congestion in a way that reduces overall costs.

“For the most part, it has generally worked very well and as designed,” SPP’s Gerardo Ugalde said. “We had a few issues … and a few procedures were eliminated.”

Through Feb. 15, the RTOs have had 1,075 M2M events (343 requiring settlements), which resulted in $9.5 million changing hands, according to a review of the first year. Two-thirds of the M2M payments came from three SPP flowgates in Nebraska. The RTOs’ analysis showed the shadow prices are generally within $30 of each other.

“[Those] 1,200 miles are, by far, the largest seam of any RTO we’re aware of,” said SPP’s David Kelley, director of interregional relations. “It has become a lot more complex with the integration of the Integrated System.”

Ugalde said shadow prices and price convergence remain the biggest issues along the seam. “The majority of the time, we’re able to [keep prices] under $500” per megawatt-hour, he said. “For the most part, we tend to price converge.”

MISO and SPP told stakeholders they are continuing their development of an MOU to “ensure cost-effective solutions for both markets.” The MOU, they said, will address ineffective real-time coordination on some flowgates, correct calculation errors in settlements and improve some settlement rules.

Seven Principles

Staff has developed a list of seven principles for the MOU. Among them: excluding reciprocal coordinated flowgates from the M2M process based on a threshold test for generators that affect it; recalculating firm-flow entitlements (FFE) due to changes in facility ratings; and capping FFEs to the system operating limits (SOL) for M2M flowgates.

Another principle would give the non-monitoring RTO the ability to switch from controlling market flows to total flow control. MISO’s Ron Arness said he hoped controlling all transmission on a flowgate rather than just market flows will help moderate some of the price and power swings he has seen on the SPP side. He said new processes on the PJM seam have addressed similar situations.

“What we’ve seen with the SPP flowgates is the [swings] are more severe [than PJM’s],” Arness said. “We need to tweak that process.”

Kelley said SPP’s stakeholders are “not comfortable” with exchanging ownership of flowgates. “It’s really who has the more efficient, effective generation to control the constraint,” he said. “There’s no way you can control the SOL when MISO has 900 MW of generation flowing.”

In response to a question by American Electric Power’s Kip Fox, Ugalde said the MOU will solve “60 to 70%” of the M2M problems.

Ugalde said some of the MOU’s provisions will require JOA changes be filed at FERC, while others will necessitate software changes. The RTOs will continue to evaluate the day-ahead exchange of FFEs and settlements.

MISO’s Beibei Li shared an analysis she and others at the RTO have conducted with PJM on interface pricing. Li said the results indicate a common interface method has “merit” in resolving pricing issues.

Adam McKinnie, chief utility economist for the Missouri Public Service Commission, questioned the analysis. “A lot of time and treasure has been spent between MISO and PJM discussing these various options, but you’ve never been able to say how much this will save,” he said.

Li hedged her response by noting congestion varies from year to year. “Compared to the ideal — where we want to be and where we were — we have identified $2 million in improvement opportunities,” she said.

“I wonder whether you’ve already spent the savings on analysis,” McKinnie responded.

‘Freeze Date’

Work is also continuing through the Congestion Management Process Council, which includes SPP, MISO and PJM, to update the 2004 “freeze date” used in determining CMP allocations and FFEs, based on pre-market firm flows. Arness said the council’s members have agreed there is a need to work on freeze-date alternatives, with the goal of making a Tariff filing by year’s end.

“We would like to have an indication we can move forward by the end of the year,” Arness said. “We’ve heard this will be tough, but we’re still working on it.”

Arness said the CMPC has approved guiding principles for firm-flow allocation calculations and a procedure to calculate market-flow impacts associated with external pseudo-tied resources.

However, the council has not been able to move forward with using long-term auction revenue rights to develop M2M FFEs. The RTOs have compared each other’s ARR nomination process and discovered similarities and differences.

MISO, SPP Considering Second Joint Tx Study

By Tom Kleckner

LITTLE ROCK, Ark. — SPP and MISO’s Interregional Planning Stakeholder Advisory Committee met last week to discuss how to improve a process that failed to recommend any interregional projects during its first go-round in 2015.

As required by the RTOs’ joint operating agreement, the IPSAC’s March 9 annual issues review meeting was intended to determine whether a joint study should be performed this year and, if so, what should be in the study’s scope.

Though stakeholders expressed an appetite for another study, they will first provide written feedback to the IPSAC. The committee will then provide a study recommendation to the RTOs’ Joint Planning Committee, which will vote to determine whether a coordinated system plan (CSP) study should begin this year and which transmission issues should be studied.

The JPC — comprising David Kelley, SPP’s director of interregional relations, and MISO’s Eric Thoms, manager of planning coordination and strategy — will be given 45 days to vote after receiving the recommendation.

“When we designed the process, we didn’t want a joint-study process that drags on and on,” said Brett Hooton, SPP’s senior interregional coordinator, in explaining the 45-day timeframe.

‘Triple Hurdle’

Stakeholders will provide comments on the CSP process’ suggested improvements and issues, which included overburdened flowgates, market-to-market congestion, carbon-constrained futures, the MISO North-South flows and what American Electric Power’s Kip Fox “affectionately” refers to as the “triple hurdle” approval process for interregional projects.

“To get through the regional process, a project has to get through three models, three different sets of criteria,” said Fox, AEP’s director of transmission strategy and grid development. “That makes it very difficult to build across the seam.”

The JOA currently requires interregional projects to be agreed upon by both RTOs, improve congestion by at least 5% on either side of the seam and be approved through the respective regional reviews. SPP approval requires a 1.0 benefit-to-cost ratio, while MISO approval requires a 1.25 B/C ratio and limits projects to 345 kV or above.

The first joint study evaluated 67 potential transmission projects and identified three congestion-relieving upgrades, but it was unable to move forward with any of the three. (See SPP, MISO Conclude Joint Study Empty-Handed.)

Several stakeholders said they favored a more targeted study to analyze specific topics instead of another comprehensive process. “We don’t want to see another comprehensive study. Great information, but not very helpful,” said George Dawe, vice president for Duke American Transmission Co.

“We identified three projects and none of them had steel put in the ground,” Fox said. He offered two options to eliminate the triple hurdle: 1) a new interregional project category to allow easier approval and cost allocation, including voltages as low as 100 kV; and 2) adding new benefit metrics following both interregional and regional studies.

“The [adjusted production cost] doesn’t capture all the value of transmission along the seam,” Fox said. His suggested new metrics would include avoided costs, net load payments, and reduced emission rates and operating reserves.

Fox also urged the two RTOs be more flexible with their interregional projects and negotiate solutions beneficial to both sides.

‘Common Sense’

“Let’s use a little common sense,” Fox said. “We want to pay our fair share; you pay your fair share.”

“I think that works when both parties are interested in projects,” responded Jake Langthorn, Oklahoma Gas & Electric’s RTO policy director. “I’m confident SPP wants to do some projects. I don’t have same confidence MISO wants to do any projects.”

MISO bore the brunt of stakeholders’ dissatisfaction with the CSP process. Adam McKinnie, chief utility economist for the Missouri Public Service Commission, said he is “not always impressed” with MISO’s regional studies. Marguerite Wagner, ITC Holdings’ director of SPP RTO policy, said MISO’s 345-kV threshold makes it difficult to fund interregional projects. She noted congested flowgates are constrained by lower-voltage projects.

Davey Lopez, MISO advisor of planning coordination and strategy, discussed a “quick hits” analysis recently conducted with PJM, suggesting a similar process with SPP. However, DATC’s Dawe was skeptical.

“To me, quick hits equals sub-optimal projects,” he said. “I remember quick hits. We got there because we couldn’t do anything through the [PJM] IPSAC.”

A stoic Thoms took much of the criticism in stride. He said MISO “left no stone unturned” in the last joint study, but the cost benefits of the proposed projects “haven’t been there yet.” He said addressing the 345-kV threshold issue is one of MISO’s top priorities.

“I agree finding interregional projects has been elusive,” he said. “MISO sees value in doing coordinated studies and joint evaluation with SPP. We will take all the information here, meet internally, and make that determination as to whether to do another coordinated joint study and what that scope will look like.”

CPP Impacts

DATC’s Bob Burner focused his company’s suggestions on the Clean Power Plan’s impacts and the MISO North/Central-South constraint. Burner said an interregional analysis is needed to better understand the new PROMOD models MISO introduced last year in its Transmission Expansion Planning package.

Wagner likened the SPP-MISO north-south constraint to renting a car, and said transmission expansion could replace MISO’s settlement payments for flows across the seam. “You have these payments, but nothing long-term … no increased flexibility, no increased robustness of the system,” she said. “It’s current money, and you’re going to be paying that into perpetuity instead of for something that might be longer-lasting.”

SPP’s Adam Bell, representing its interregional relations department, reviewed with stakeholders initial feedback gathered by the IPSAC in December following the first study’s conclusion. He said staff reviewed the suggestions it has already received, separating them into process-improvement options, scope-related suggestions and issues to be addressed later.

“We knew this being the first time through the process, we would have significant room for improvement, and that turned out to be true,” Bell said.

Potential improvements include aligning the system plan’s timing with SPP’s Integrated Transmission Process and the MTEP process; aligning the CSP’s models with the RTOs’ regional models; using broader metrics; creating task teams to create more transparency for stakeholders into the process; and providing more information on why projects did not pass screens or were not recommended as interregional projects.

Bell also suggested creating a separate interregional evaluation process to replace SPP’s and MISO’s separate regional review processes and requiring the respective boards of directors to vote up or down on any project recommended by the JPC.

Kelley noted interregional projects have to come through the Order 1000 process. “In lieu of separate regional reviews, we would rely on the results of the interregional evaluations,” he said. “We will still go through three [sets of] approvals but rely on only one review.”

Added Complexity

With the addition of the Integrated System, staff pointed out, the MISO-SPP seam is now approximately 1,200 miles long, and includes more than 60 interconnections, adding to the complexity of determining interregional projects. The concentration of wind energy in the upper Midwest has only exacerbated the situation.

Dan Lenihan, manager of transmission and distribution planning for the Omaha Public Power District, said Nebraska has historically seen heavy north-to-south flows in the summer and a reversal during the winter. “With the large addition of variable energy,” he said, “we’ve seen those north-and-south flows flip on almost a daily basis, depending on how the wind blows.”

“I’m always surprised how this much wind can be added without the transmission to support it,” said Paul Malone, transmission compliance and planning manager with the Nebraska Public Power District. “We’re looking for mitigation on this, or MISO can build some more outlet transmission.”

Xcel Energy asked the RTOs to examine the “very complex” seam along North Dakota. “We would like to determine if any efficiencies in interregional coordination can be found to increase system reliability and provide more cost-effective operational solutions,” said Drew Siebenaler, a transmission and regional planning engineer with Xcel.

Several other stakeholders suggested future studies take into account the growing development of wind energy and other renewables, which are crowding out coal generation.

“Most people acknowledge we’re seeing a shift to lower-carbon generation. I think we missed that in the last study with the [business-as-usual] case,” said the Wind Coalition’s Steve Gaw. “I think it makes sense to make that commitment in the studies going forward. I think it very important, especially considering the seams have increased in distance and we’re involved in a lot more states now.”

Kelley, while welcoming the feedback and asking for more from the stakeholders, pointed out such a study would be the time-consuming, 18-month analysis to which some were objecting.

“If we were to look at a carbon-constrained future, that would be a comprehensive, broad study,” Kelley said. “We could do the exact study we just did, except the [business-as-usual case] would be a carbon-constrained future instead.”

PJM Market Implementation Committee Briefs

VALLEY FORGE, Pa. — Two proposals that would have delayed the disclosure of financial transmission rights ownership following an auction were defeated by the Market Implementation Committee on Wednesday.

Bruce Bleiweis of DC Energy offered a package that would have allowed PJM to post aggregate data after an auction, mask ownership data for three to six months and disclose ownership after one year. It garnered only 10% of a sector-weighted vote.

A PJM proposal would have aligned the release of data with how the RTO treats other information, disclosing full ownership after four months. It received only 21% in a sector-weighted vote. (See “Proposals Would Delay Posting of FTR Ownership,” PJM Market Implementation Committee Briefs.)

Bleiweis said his proposal was intended to provide FTR owners the same confidentiality as other market participants.

The rejections were not a surprise. Several members and Market Monitor Joe Bowring had expressed opposition when Bleiweis won MIC approval of a problem statement to explore the issue in September.

Day-ahead Submission Deadline Moved up

Members endorsed updates to PJM’s regional transmission and energy scheduling practices intended to improve the alignment of the gas and electric markets.

A five-minute “shotgun” start window was created for hourly spot-in reservations (spot market imports), and the day-ahead bid submission deadline was moved from noon to 10:30 a.m.

Operating Parameter Definitions Approved

The committee approved short-term operating parameter definitions and voted to amend a problem statement to set June 1, 2017, as the deadline for permanent clarifications of the terms.

The amendment was proposed by Bob O’Connell of Main Line Electricity Market Consultants and included some clarifications to the terms cold/warm/hot start-up time, minimum run time and cold/warm/hot soak time.

PJM’s definitions were approved by 82% of the members in a sector-weighted vote. O’Connell’s definitions were approved by 60% of the vote. Both proposals will advance to the Markets and Reliability Committee, although O’Connell’s definitions will not be considered if PJM’s definitions are approved.

Clarifications Sought for Bilateral Transactions

Members approved a problem statement and issue charge to clarify rules on how auction-specific bilateral transactions credit bonus payments and indemnification. (See “PJM Proposes Clarifications to Capacity Bilateral Transactions,” PJM Market Implementation Committee Briefs.)

In such transactions, a seller transfers capacity to a buyer, but the obligation for performance remains with the seller.

The problem statement seeks to clarify how nonperformance charges and bonus payments apply to such transactions, and how they would be treated in litigation such as bankruptcies.

PJM Operating Committee Briefs

VALLEY FORGE, Pa. — PJM members last week approved manual and Tariff changes dictating the ramp rates Capacity Performance resources will have to meet to avoid penalties during performance assessment hours.

PJM said it found that many generators are able to increase their output faster than reflected in the ramp rates plant operators entered in Markets Gateway. The new rules will measure generators against the unit’s actual ramp performance between Jan. 1 and March 31, 2016 (or June 1 to Aug. 31, 2015, for units not dispatched in the first three months of this year).

Units would be excused from penalties if they are following PJM dispatch or had approved outages.

The approach is a short-term solution that PJM hopes to have in place before the delivery year starts June 1.

The Markets and Reliability and Members committees will be asked to endorse the changes on March 31, following a special OC session highlighting ramp rate examples on March 22.

PPL SPS to be Removed

A special protection scheme to prevent generator instability if the Susquehanna-Wescosville 500-kV line ever fell onto the Susquehanna-Harwood 230-kV lines is no longer needed with the addition of the Lackawanna-Hopatcong 500-kV line, according to PPL. The SPS — which would have resulted in tripping Susquehanna Unit 1 — will be removed during an outage of the nuclear unit and should be complete by April.

Dominion Zone SPS Retired

A special protection scheme installed in 2007 in the Dominion zone was retired last month. The SPS addressed potential thermal overloads on the Carolina-Kerr Dam 115-kV line. The scheme is no longer needed with the completion of Regional Transmission Expansion Plan project b1793 to rebuild Kerr Dam-Carolina line 22 and project b1793.1 to remove the Carolina 22 SPS.
