SPP Readies for Winter with Improved Wind Forecasts, Gas Coordination

By Tom Kleckner

SPP says improved wind forecasting and coordination with gas pipelines have the RTO well prepared for the coming winter.

SPP engineer Jon Langford said during the RTO’s annual winter preparedness emergency operations call last week that its wind forecaster, Energy & Meteo Systems, has developed a full icing forecast. The forecasting tool, to be delivered in November, compensates for freezing temperatures that shut down wind turbines’ directional systems.

“The wind farm works, but the equipment that turns the turbine [in the direction of] the wind stops working,” Langford explained.

He said SPP’s winter peak load is expected to near 38,000 MW, “if we get close to what we did last year.” That number is less than half of the footprint’s 83,465 MW of capacity.

The winter emergency operations plan is available online but requires a password.

C.J. Brown, manager of SPP’s balancing-authority functions, reminded stakeholders of the Oct. 1 switch to the new gas-day timeline as a result of FERC Order 809. (See “New Gas-Day Nom Process on Track for Oct. 1 Go-Live,” SPP Briefs.) Market participants will now submit their bids and offers by 9:30 a.m. instead of 11 a.m.

“From SPP’s perspective, this presents a good step in the direction where we can be a little more efficient and a little earlier,” Brown said. He also said the RTO has increased its communications with gas suppliers.

“We sure don’t want to rest on our capacity margin and our infrastructure,” Brown said.

Jeff Johnson, a meteorologist for Schneider Electric, predicted below-normal temperatures this winter for SPP’s footprint. He said a slight warming trend in February would be followed by more cool weather in March.

Johnson said the Pacific Decadal Oscillation (PDO), a pattern of oceanic climate variability extending from Alaska to Hawaii, will result in a winter similar to the 2013-14 and 2014-15 seasons.

The PDO “tends to produce a more northerly component to the jet stream,” he said. “That helps deliver more Arctic air out of Canada into the central part of the country.”

Hot Topic: MISO Stakeholders Weigh in Again on Forward Auction Proposal

By Amanda Durish Cook

ST. PAUL, Minn. — MISO stakeholders last week continued their critique of the RTO’s proposed Competitive Retail Solution.

MISO’s proposal and the broader issue of resource adequacy were the “hot topic” at last week’s Advisory Committee discussion moderated by consultant Robert Gee.

Gee began by asking sectors if MISO’s separate forward auction for retail-choice zones was reasonable — or even necessary.

Dynegy’s Mark Volpe said the Independent Power Producers sector believes that a serious problem exists, pointing to the forecasted generation shortfalls in Illinois and Michigan and the 1.9 GW of generation that’s currently pseudo-tied out of Illinois into PJM.

5 GW Departing

“You’ve got 5 GW of generation in southern Illinois — if you count the retirements and suspensions — that’s departing MISO. That’s huge. … It’s clear evidence that a problem exists and has existed for years that needs to be addressed yesterday,” Volpe said.

The IPP sector submitted comments suggesting MISO conduct voluntary forward auctions for regulated states and a “mandatory auction for retail-choice load.”

The Transmission-Dependent Utilities sector has not reached consensus on whether MISO’s forward auction addition is necessary, WEC Energy Group’s Chris Plante said. “I think we have a plurality of members who are opposed to the Competitive Retail Solution,” Plante said. He added that incremental changes could be made, including raising the cost of new entry to two or three times its current amount.

Northern Indiana Public Service Co.’s Paul Kelly said the Transmission Developers sectors is not answering whether the CRS is needed anymore, as it’s clear MISO will file the auction redesign for FERC approval anyway.

“What we’re willing to say as a sector is that the concerns we had have been addressed by MISO, and we’re appreciative of that,” Kelly said. “It’s not as if a forward auction hasn’t existed in America, so we’re not blazing a new trail.”

‘Totally Dysfunctional’

Madison Gas and Electric’s Megan Wisersky, of the TDU sector, said just because a forward auction has been done elsewhere, doesn’t mean it’s been done correctly.

“The eastern forward capacity markets are completely, totally dysfunctional,” Wisersky said. “More and more people are dragged into it, kicking and screaming. We’re not solving it by chasing this ephemeral idea that changing capacity markets are the way to fix it. If you really want to think about it, capacity isn’t even a real product — energy and ancillary services are.” (See related story, Monitor: NYISO Needs Locational Focus, Flexibility — not Forward Capacity Market.)

The Illinois Industrial Energy Consumers’ Jim Dauphinais, speaking for the End-Use Customers, reminded the Advisory Committee that Lower Michigan and Illinois will pay for what is decided. Dauphinais said he was not convinced that a major market change was needed at all and that MISO’s current proposed market rules are “unnecessarily complicated.”

“It treats retail load like an outcast,” Dauphinais said. He said the Independent Market Monitor and MISO’s hybrid solution, which kept both merchant and regulated load on the same prompt auction schedule and applied a sloped demand curve to merchant load, was more reasonable.

Volpe said MISO’s Board of Directors and management should pay attention to the Monitor’s “deep-seated” concerns on price formation in a bifurcated market.

The Public Consumer Group sector voiced concerns that generators in regulated states could voluntarily bid into the forward auction, making them unavailable for local customers. The sector called on MISO to conduct annual testing to confirm actual available capacity amounts.

The Power Marketers sector said moving the auction for competitive areas three years out gives market participants time to plan and budget. The TDU sector countered that argument, claiming MISO has changed the capacity process so often year to year that it has become difficult for utilities to get their bearings. “MISO’s processes in this area have been changing every year since 2009, and the lack of consistency and predictability from year to year creates problems for utilities trying to do their own planning,” the sector wrote.

‘Slippery Slope’ Fear

After multiple stakeholders called the forward auction “a slippery slope,” MISO Director Paul Bonavia asked why stakeholders believed the forward auction construct would eventually cross into traditionally regulated areas.

Once filed with FERC, “I cannot imagine … the possibility that MISO … would apply this proposal to the entire footprint,” Volpe said.

“FERC is not shy about pushing jurisdictional boundaries,” Wisersky fired back.

Matt Brown, representing the Transmission Owners sector, said that while the risk of spreading applies to any new regulation, his sector wasn’t worried MISO would apply a PJM-style forward capacity market to the entire footprint.

“Last I checked, MISO wants to be an RTO five years from now,” NIPSCO’s Brown said, referring to the voluntary nature of RTO membership. “I think MISO has done a good job recognizing that what Michigan and Illinois needs is very different from what the rest of the market needs.”

Bonavia said that while the board wasn’t going to “jump in and start writing Tariff language,” it has heard the concerns.

“It doesn’t sound like — to nobody’s great surprise — that there’s a lot of accord on the Competitive Retail Solution. But I’ll say this as one director: It feels that there’s a pretty strong sense to assure it’s a regional solution that doesn’t bleed over or create the slippery slope that sucks other states into it.”

Awaiting the Details

Indiana Utility Regulatory Commissioner Angela Weber, representing the State Regulatory sector, said she is not sure whether the proposal is reasonable because details, such as the shape of the forward demand curve, have not yet been provided.

Weber said she wanted to make sure that the demand curve is shaped so both competitive and regulated areas in MISO achieve equal reliability and uphold the one-day-in-10-year loss-of-load expectation.

Comments from the State Regulatory sector urged the RTO to “keep in mind that resource adequacy within MISO is largely a state and local responsibility” and said it was “imperative that the current Competitive Retail Solution is shown not to impact existing state and local authority and processes.”

A day later at the MISO board meeting, Director Thomas Rainwater wondered if the problem in Southern Illinois was being “overstated” by the RTO.

Richard Doying, executive vice president of operations and corporate services, said that whether or not the predicted shortfall in the Organization of MISO States survey is accurate, new generation that “no one is building” will be needed in Zone 4. Efficient pricing achieved through the forward auction, Doying said, will encourage investment in new generation.

CAISO Monitor Seeks Congestion Revenue Rights Auction Reforms

By Robert Mullin

CAISO paid congestion revenue rights holders $27 million more than it took in from CRR auctions during the first half of the year, according to the ISO’s Department of Market Monitoring.

That equates to 63 cents in auction revenues for every dollar paid out, leaving California electricity consumers to foot the difference — which mostly goes to speculators, the Monitor says.

The department wants the ISO to address the issue by eliminating or reforming the auction process.

“There’s a shortfall between payments and revenues in the auction, and this money is really ultimately paid by the ratepayers in the market,” Gabe Murtaugh, a department senior analyst, said during a Sept. 14 call to discuss the department’s second-quarter market performance report.

CAISO congestion revenue rights — The graph shows that payments to congestion revenue rights holders consistently exceed the amounts taken in by the ISO during auctions.

The Monitor reasons that ratepayers — who ultimately bear the costs for transmission access charges paid by load-serving entities — are entitled to receive the revenues from transmission.

“When auction revenues are less than the payments transferred to other entities purchasing congestion revenue rights at auction, the difference between auction revenues and congestion payments represents a loss, which is paid out from the day-ahead congestion rent,” the department’s quarterly report explained. “The losses therefore cause ratepayers, who ultimately pay for the transmission, to receive less than the full value of their day-ahead transmission rights.”

Financial traders are the biggest beneficiaries of the current CRR market design, the Monitor has found. During the first half of 2016, those companies made $22.7 million in profits, more than doubling their investments as they paid 49 cents into the ISO’s auctions for every dollar earned.

Over the same period, power marketers and generators took in about $3.9 million and $800,000, respectively, paying 82 and 85 cents for every dollar of congestion revenues earned.

This year’s mismatch extends a pattern that has persisted for nearly five years, Murtaugh said. Since 2012, CRR payments have exceeded auction revenues by more than $500 million.

It all adds up to a need for a change in how the ISO administers the CRR process, the Monitor contends.

One specific recommendation is that the ISO should end the practice of auctioning off excess transmission capacity to third parties after LSEs have received their CRR allocations.

“With this approach, the ISO could still run a market for congestion revenue rights,” the Monitor said. “However, this market would be run only with bids voluntarily submitted by various participants willing to essentially buy or sell congestion revenue rights.”

In other words, the only CRRs available to market would be those allocated to LSEs. CRRs would only be sold if there was a market participant willing to take on the obligation to pay congestion revenues at the market clearing price, thereby reducing ratepayer exposure to market shortfalls.

“In this market, any entity that values hedging against locational price differences, such as generators or marketers, could submit bids to purchase congestion revenue rights,” the Monitor said. “Financial entities, other participants willing to sell hedges or entities wishing to speculate on locational price differences could submit bids to sell congestion revenues rights.”

The Monitor said it is prepared to work with the ISO and stakeholders on additional options to change the CRR market and noted that the ISO’s management is considering adding the issue to its stakeholder initiative catalog this fall.

PJM Attempting to Usurp Market Mitigation Role, Monitor Says

By Rory D. Sweeney

PJM is trying to usurp the Independent Market Monitor’s authority to regulate fuel-cost policies and consequently increasing market participants’ ability to exercise market power, the Monitor argued in a protest Friday (ER16-372).

PJM’s proposed plan for evaluating fuel-cost policies, filed Aug. 16, “would substantively change the roles of PJM and the Market Monitor in the review of offers for market power in a manner inconsistent with the Tariff’s specifications of roles,” IMM staff wrote. “Participants will have the ability and incentive to submit inaccurate cost-based offers.”

The debate over the rules governing fuel-cost policies stems from a 2015 FERC order requiring the RTO to allow day-ahead offers that vary by the hour and the ability of generators to update offers in real time. (See Heeding Stakeholders, PJM Reduces Proposed Fuel-Cost Penalties.)

The Monitor said that daily offers limited generators’ “ability to exploit real-time constrained conditions.” The switch to hourly offers, it said, requires “increased rigor” in mitigation design and the implementation of the three pivotal supplier test in addition to fuel-cost policies.

Other responses to PJM’s filing largely supported the RTO’s effort to develop hourly offer rules, but they differed on how fuel-cost policies should be handled and what role the Monitor should play.

‘Define the Roles’

The Pennsylvania Public Utility Commission and the Delaware Public Service Commission said in a joint filing that “PJM’s [fuel-cost policies] proposal undermines the Independent Market Monitor’s role in detecting and addressing market power concerns” and urged FERC to adopt the Monitor’s standards.

In a joint filing supporting PJM’s proposal, American Electric Power, Dayton Power and Light, FirstEnergy, Duke Energy, Buckeye Power and the East Kentucky Power Cooperative asked the commission to “plainly define the respective roles” of PJM and the Monitor in the process.

“Market sellers are squarely in the middle of a perfect storm created by ambiguous governing documents, new commission directives and a complete lack of clarity concerning the role of the IMM,” the group wrote. “The result is untenable risk associated with submitting cost-based offers without approved fuel-cost policies. Failing to act timely, or at a minimum to preserve the status quo while the commission deliberates, will perpetuate an already fraught state of affairs.”

Dominion Virginia Power reiterated those sentiments in its filing, asking “that the commission establish final authority with one entity.”

The Organization of PJM States Inc. asked FERC to view the docket in a larger context. “Discounting the IMM’s current role could provide a signal to resources that they would no longer be held fully accountable to IMM oversight, potentially eliminating the proper incentive to submit accurate cost-based offers,” OPSI wrote. “The commission should consider the broad implications of approving any filing that usurps the IMM’s existing market power authorities.”

The American Petroleum Institute focused on the structure of the policy itself, saying the rules “need to provide generators some degree of flexibility to procure fuel in the lowest cost manner.” Specific rules about how to procure fuel “may restrict generators in a way that could lead to higher consumer costs.”

API also protested PJM’s proposal that all policies on which the RTO and the Monitor can’t agree on should be referred to FERC’s Office of Enforcement. The group called for a dispute-resolution process instead.

No ‘Bright Line’

The PJM Power Providers Group agreed procurement practices shouldn’t be dictated. “The purchasing of fuel for power generation is a complicated and thoughtful piece of any generator’s business strategy,” P3 wrote. “PJM and the IMM should not attempt to replicate the market or impose a formulaic evaluation on generators, as such a task would prove nearly impossible and more likely lead to chaos during times of system stress.”

Dominion agreed that PJM’s proposal is too restrictive. Fuel-cost policies should not be “a pre-existing, bright-line formula for all market conditions,” Dominion wrote. “This expectation is unrealistic and made more unreasonable by PJM’s failure to first require consultation regarding suspect cost-based offers before they are deemed to be not in compliance with a resource’s fuel-cost policy.”

The company called for a system similar to ISO-NE’s, in which its Internal Market Monitor estimates a competitive offer that creates a “reference price” against which all market offers are compared. It also asked that PJM’s proposed penalty — requiring units without an approved policy to submit an offer of $0 — be replaced with a less punitive option and that companies not be required to submit a policy for each type of fuel at a unit, estimating it would need to maintain more than 100 separate policies.

No matter what FERC’s decision, it should be made quickly, P3 urged. “Every winter that passes without hourly offer flexibility is a winter in which the market is less efficient, suppliers are exposed to inadequate cost recovery and reliability is potentially” compromised, the group wrote.

Monitor’s Proposal

The Monitor proposed a clear delineation between the responsibilities of PJM, which would conduct a compliance review with IMM input, and the Monitor, which would conduct a market-power review without PJM involvement. The Monitor said its review will ask that policies are algorithmic, verifiable and systematic. They would need to show:

a set of defined, logical steps;
a fuel price that can be calculated by the Monitor after the fact with the same data available to the generation owner at the time the decision was made and documentation for that data from a public or a private source; and
a standardized way for calculating fuel costs including “objective triggers” for each method.

PJM proposed a joint review that it would control with input from the Monitor. The RTO’s proposal creates “a critical flaw” because it doesn’t “preserve the Market Monitor’s role in market-power reviews and to tie the consequences for noncompliance to that review,” the Monitor said.

Federal Briefs

Energy Secretary Ernest Moniz said that Congress should pass tax credits to incentivize clean-coal projects, preserving coal’s viability as a fuel.

The comments came as Moniz, speaking at the Mid-Atlantic Region Energy Innovation Forum in West Virginia, deflected charges the Obama administration has treated coal unfairly. “Plain and simple, ‘War on Coal’ is not what this administration has as a policy or has done,” he said. “It starts with — make no bones about it — we and the world are heading to a low-carbon future.”

But he still sees coal as an important fuel source going forward. “Getting the tax credits this year would be a very, very big deal,” Moniz said. “And having the tax credits in place in a trajectory for carbon reduction, in my view, is what the investment community needs.”

Senate Passes Water Bill with Coal Ash Amendment

The Senate passed a water resource infrastructure bill with an amendment that would give states more authority over permitting and the enforcement of coal ash disposal.

The Water Resources Development Act of 2016, which authorizes $10.6 billion in water project funding, also adjusts the Solid Waste Disposal Act to give states authorization to institute their own coal ash disposal rules instead of EPA’s rules. The state standards would have to be “at least as protective” as federal standards.

Environmental groups said the new amendment could result in confusion. “The proposed legislation could effectively remove the EPA rule’s federal minimum stands, which could lead to a patchwork of regulatory requirements,” the Environmental Integrity Project and the Waterkeeper Alliance said in a letter.

NJ, Fed Agencies File Critical PennEast Comments with FERC

Ahead of Monday’s deadline, several federal and New Jersey government agencies filed comments with FERC last week criticizing the commission’s draft environmental impact statement on the proposed PennEast Pipeline.

Among the federal agencies that filed comments were the U.S. Fish and Wildlife Service, the National Park Service and EPA, the last of which concluded the proposed 118-mile pipeline would cause “significant adverse environmental impacts.” The agencies also said the draft EIS omitted a significant amount of information.

The New Jersey Department of Environmental Protection and the New Jersey Rate Counsel were also critical, with the latter saying the developers failed to justify the need for the pipeline. The $1.12 billion project, being developed by a consortium of several companies, would deliver shale gas from Northeastern Pennsylvania into New Jersey.

House Passes Advanced Nuclear Technology Framework Bill

The House of Representatives last week passed a bill that directs the Nuclear Regulatory Commission to create a regulatory framework and criteria that would allow for the licensing of advanced nuclear reactors.

The Advanced Nuclear Technology Development Act of 2016, sponsored by Reps. Bob Latta (R-Ohio) and Jerry McNerney (D-Calif.), requires the Energy Department and the commission to collaborate on the licensing process in order to provide certainty to developers of the technology, which includes molten salt reactors and supercritical water reactors.

“This bill will help provide certainty for innovators and entrepreneurs who are seeking to develop and license the next generation of nuclear technologies,” House Energy and Commerce Committee Chairman Fred Upton (R-Mich.) said. “We should ensure that the Nuclear Regulatory Commission has the expertise and resources to review and license the latest in advanced reactor technologies, and this bill does just that.”

Tribe Wants Review of Enbridge Settlement

A Michigan Native American tribe said it was never consulted on an agreement between Enbridge and EPA in which the company will pay a $61 million fine and spend $110 million in pipeline upgrades to settle claims relating to the 2010 oil spill in the Kalamazoo River.

Part of the settlement calls for upgrades to Enbridge’s Line 5, which carries crude oil beneath the Straits of Mackinac. The Grand Traverse Band of Ottawa and Chippewa Indians, which has fishing rights to the straits under an 1836 treaty, said it was never consulted on the settlement terms.

An attorney representing the tribe said it would have called for a full environmental review of Line 5. Any actions Enbridge takes on that line now are not covered by review requirements. The tribe wants the Kalamazoo spill settlement reopened for review. A Justice Department spokesman said the objection is under review.

NRG Wins Bid for SunEdison Renewable Projects

nrg NRG Energy successfully bid to acquire renewable energy projects around the country from bankrupt SunEdison for $144 million.

The sale, which needs to be approved in bankruptcy court, includes the 200-MW Buckthorn solar farm in West Texas. The project, slated for completion next year, would make the city of Georgetown the largest municipality in the nation powered solely by renewable sources. NRG already owns some wind projects in Texas; the deal would give the company its first solar plant in the state.

The deal could grow to $188 million if milestone benchmarks are met. It also includes solar and wind projects in Utah, Washington, California, Maine and Hawaii. Most of the projects remain in development and require additional investment.

AEP Seen Likely to Sell Remaining Ohio Coal Plants

American Electric Power, which just arranged a deal to sell four merchant generating stations in Ohio and Indiana, is still examining its options for four other coal-fired plants in Ohio with a capacity of 2,671 MW.

One option is to continue to push for reregulation in the Ohio legislature, which could prove to be a long and difficult fight. AEP would prefer to operate in a regulated environment in order to lock in rate certainty. But industry observers believe the more likely option is for AEP to put the plants up for sale.

“We think an outright sale of these assets in 2017 is the most likely outcome,” wrote analyst Andrew Bischof of Morningstar, which values the plants at $800 million.

Amazon Investing in Texas Wind Farm

Amazon is collaborating with Chicago’s Lincoln Clean Energy to build a 253-MW wind farm in Texas that will open by the end of next year. The Amazon Wind Farm Texas will include more than 100 wind turbines that will power Amazon facilities, including its cloud data centers.

Lincoln will build and own the wind farm, but Amazon is contracting to buy 90% of the generated power. “Amazon Wind Farm Texas is our largest renewable energy project to date and the newest milestone in our long-term sustainability efforts across the company,” Kara Hurst, Amazon’s director of sustainability, said last week.

The wind farm is Amazon’s most recent expansion into the Lone Star State. The online shopping giant opened a new “Silicon Hills” corporate hub last year in Austin and, in 2014, leased out office space at the Dallas Galleria complex. Amazon has two Dallas-area warehouses, or “fulfillment centers,” and a large warehouse and customer service center outside of San Antonio.

Apache Works to Calm Fracking Fears Around New Texas Site

Apache Corp. executives are migrating to the town of Balmorhea, Texas, to assure the public that its recent oil and gas discovery in the Permian Basin won’t contaminate the San Solomon Springs. The nearby Balmorhea State Park is centered around a 3.5-million-gallon pool filled and fed by the springs, which keeps the park at a cool 72 to 76 degrees even in summer.

While Apache has leased the mineral rights under the state park, and under the town itself, the company promises not to drill on or under either. The company met with residents and officials in the region Friday to explain how it will keep the oil and water separated.

Apache announced the Permian Basin discovery this month. It said it expected to find more than 15 billion barrels of oil and gas under 350,000 acres near Fort Davis, Texas.

Analysis Recommends Continuing Reduced Con Ed-PSEG ‘Wheel’ for Grid Stability

By Rory D. Sweeney

VALLEY FORGE, Pa. — A power-flow analysis indicates a reduced version of the current flow pattern is the most reliable resolution when the Con Ed-PSEG ‘wheel’ ends on April 30, PJM and NYISO officials said last week.

The grid operators are recommending an “operational base flow” that continues to route 400 MW from upstate New York to New York City through northern New Jersey, a reduction from the 1,000 MW in the current wheel.

Consolidated Edison decided not to renew the wheel arrangement — which it used to move power from upstate New York through Public Service Electric and Gas facilities in northern New Jersey to serve its load in New York City — in a transmission cost allocation dispute. (See PJM, NYISO Seek Input on Replacing Con Ed-PSEG ‘Wheel’.)

To ensure operational flexibility during emergencies, the analysis used three “extreme” cases that focused on high load and high interchange and included 16 scenarios for various interchange distribution options, PJM’s Phil D’Antonio told the Operating Committee last week. It assumed 2,500 MW in exports to NYISO and 1,500 MW in imports to PJM, which are the historical maximums, he said. The analysis applied various percentage distributions of AC interchange on the eastern interfaces (5018, JK and ABC) to determine impacts, feasibility and operational flexibility.

The eight phase-angle regulators (PARs) involved in the analysis were fixed in their pre-existing positions during an initial analysis to determine the percentage of AC interchange that flows over the eastern interfaces. “We didn’t adjust any PARS in the analysis,” D’Antonio said. “We adjusted generation to determine what the flows were.”

Limitations

The analysis identified limitations both in delivering from NYISO to PJM on three lines (A, B and C) between New York City and northern New Jersey, and from PJM to NYISO on two lines (J and K) between Waldwick in northern New Jersey and Ramapo in upstate New York — a reverse of the existing wheel flows. Limitations included exhausted PAR taps, congestion in northern New Jersey and forcing flow from a 230-kV system at Waldwick to a 345-kV system at Ramapo. That system difference seems to be “the most limiting” factor from PJM’s perspective, D’Antonio said. NYISO also found delivery issues on the A, B and C lines using an N-1-1 analysis, he said.

PJM is considering a combination solution that first accounts for the operational base flow and then applies a percentage of the remaining interchange distribution. The J and K lines would shoulder 15%, while A, B and C would receive 21%. Line 5018, a 500-kV span between Ramapo and Branchburg in central New Jersey would receive 32%, and the remaining 32% would continue to flow on several western ties that cross the Pennsylvania-New York border as currently happens.

pjm, nyiso, con ed-pseg wheel — A “reduced” Con Ed-PSEG wheel

The flows would remain largely the same, but at reduced levels. A study of that option set an operational base flow bandwidth on the J/K and A/B/C lines between 300 MW and 500 MW. That option allowed the grid operators to meet their target flows and adhere to protocols, D’Antonio said.

No Surprise

“I don’t think that should come as a surprise to anybody [that] for 30-plus years we’ve been upgrading the Public Service North system with respect to the nonconforming wheeling service, so physically that’s naturally what the system would want to do outside of trying to force flows using the PARs,” D’Antonio said.

From a market perspective, maintaining a full -1000/1000 operational base flow creates the least additional congestion costs at 1.16%. The -400/400 option creates about 50% more at 1.8%, while the strict 0/0 creates the most at 2.14%. All three options are comparable in the productions costs and load payments they create.

Dave Pratzon of GT Power Group asked if NYISO is planning to reinforce its side of the system to better balance the flows now that Con Ed will no longer pay to maintain the wheel.

Several stakeholders have voiced concerns that the proposed solution provides benefits to Con Ed similar to the existing situation but absolves the utility from any responsibility for transmission upgrades. “A lot of people see … New York continuing to lean on PJM’s transmission system,” Pratzon said.

At a joint PJM/NYISO meeting Friday, NYISO reiterated its position that the proposed solution officially canceled the wheel, even if the flows continue.

NYISO will seek stakeholder approval for the joint operating agreement changes before a planned FERC filing in November. The RTOs are targeting the first quarter of 2017 for training and implementation of the new protocols.

MISO Markets Committee of the Board of Directors Briefs

ST. PAUL, Minn. — Independent Market Monitor David Patton said that although MISO markets and operations performed well over a warmer-than-usual summer, there is room for improvement, namely in price-setting protocols.

Patton said MISO’s all-in energy price increased 9% from spring to summer, owing to increased gas prices and load. Summer load peaked at 121 GW on July 21, when a maximum generation alert was called, Patton said during a quarterly report at the Sept. 13 Markets Committee of the Board of Directors meeting.

“On several of these days, we committed a large amount of peaking resources,” Patton said. The Monitor said he was concerned that although July 21 was the hottest day of the year, prices weren’t the highest because utilities self-curtailed and demand response resources were not called on during the emergency maximum generation event. Real-time energy prices peaked at $36/MWh while the day-ahead price hit $78/MWh.

The voluntary curtailments led to a spike in revenue sufficiency guarantee (RSG) payments. Patton also said MISO committed more resources than necessary on some days because of incorrect load forecasting, leading to a “significant” uptick in RSG costs.

Todd Ramey, MISO vice president for system operations and market services, said July 21’s maximum generation event was the RTO’s first since the 2014 polar vortex and the first such event during summer in four years.

Patton also said only a few peaking resources were allowed to set prices on July 21. He said his proposal to expand the amount of resources able to set prices in extended LMP would alleviate dips in pricing during maximum generation alerts. Patton said if his ELMP recommendations were adopted, July 21’s average real-time system marginal price would have been 31% higher and real-time RSG would have been 14% lower.

MISO has said its simulations don’t support Patton’s proposal, which he first made in June’s State of the Market Report. (See MISO Study Undercuts IMM Proposal on Expanding ELMP Pricing.)

Patton also said voluntary load curtailment is “somewhat troubling” because it is not integrated well into MISO’s market and distorts pricing.

“As far as control goes, there’s very little control with voluntary curtailment,” Patton said.

Patton recommended increasing the visibility of load curtailment and categorizing it as DR. He also said MISO could better integrate load curtailment into market products.

“You’re simply raising your hand and saying please curtail?” Director Paul Feldman asked MISO management.

“How much of [the event] was operational versus how much of it was procedural? Are there things we could do from a market perspective?” asked Director Baljit Dail.

“The prices ought to go through the roof in emergency situations,” Feldman added.

Richard Doying, executive vice president of operations and corporate services, said MISO was planning to present alternatives to the Monitor’s ELMP suggestion soon.

“I think it’s good that we have the point of view from Dr. Patton, but we’ll also get the alternatives from a practical point of view,” Director Phyllis Currie said.

Additionally, Patton said the summer was characterized by high congestion in MISO South early and high congestion in MISO North throughout August.

Director Michael Curran asked if market products were keeping pace with emerging issues. “It struck me that there are so many operational and procedural issues. It seems that the market is becoming operationally challenged, and I wonder if we have the tools,” he wondered.

Patton said the results weren’t gloomy, although MISO did experience one operating reserve shortage and local emergency conditions on several days. He said MISO was able to operate at 3% above its planning reserve margin requirement and there were no significant operating reserve shortages. He also said the market performed competitively and reliably and mitigation needs were “infrequent.”

“We’re going to be in emergency conditions much more often,” MISO CEO John Bear said. “Does that mean we’re right at the edge? No.”

Currie asked if MISO had learned any lessons in communicating with balancing authorities over the summer in light of the higher loads. “I think that the current communication protocols are sufficient today,” Ramey said.

Ramey reported that the average summer day-ahead energy price was $29.55/MWh, 3.7% higher than summer 2015, propelled by a 3% increase in load. However, summer saw a 7.5% decrease in natural gas prices compared to summer 2015, averaging $2.60/MMBtu. Wind power production grew 18% from last summer, while installed wind capacity increased by 9%. Planned generation outages averaged 6.3 GW, up 10.7% when compared to last summer, and forced generation outages averaged 14.5 GW, up 6%.

MISO Attorneys Address Board Role in Capacity Auction Conflict

With the capacity auction redesign debate as a backdrop, three attorneys were on hand to clarify the board’s role when MISO’s management, stakeholders and Monitor can’t agree. (See MISO Sees Nov. 1 Filing on Forward Auction; Simulation Shows Price Disparities.)

MISO Senior Vice President of Compliance Services Stephen Kozey said no one should govern the board’s actions, but the board should “certainly” listen to all sides.

Counsel to the board Karl Zobrist said that while the board doesn’t make design changes, it can review proposals and provide or withhold endorsement. Zobrist also said the Monitor can make recommendations and intervene in FERC filings, but the board is under no obligation to advocate the Monitor’s recommendations.

“It’s important that there be a robust dialogue,” MISO General Counsel Andre Porter added.

“We need to make sure we’re listening not only to the IMM but the Advisory Committee and the stakeholders,” Dail said. “But I don’t think we should be saying, ‘This is how market design should work.’”

Zobrist said the board should not blindly defer to management. “You have the duty of care and duty of loyalty … and if you’re confident management is making a good decision, you should support it,” he said.

CAISO Issues Revised Proposal to Expand LSE Definition

By Robert Mullin

CAISO last week released a final draft proposal to expand the definition of a “load-serving entity” to include organizations purchasing wholesale power to serve their own needs.

The ISO’s latest draft seeks to address market participants’ concerns that the wording of the initial proposal could subject them to unwanted obligations. (See CAISO Proposes Broadening LSE Definition.)

CAISO’s Tariff currently recognizes LSEs as only those entities that sell electricity or serve load to end users, a description that covers utilities, federal power marketing agencies and community choice aggregators. A special provision is made for the State Water Project (SWP), a California agency that directly engages the wholesale market to cover its own energy requirements.

The ISO seeks to broaden the definition to accommodate the San Francisco Bay Area Rapid Transit District (BART), which, like the SWP, serves its own load but does not meet the standard definition of an LSE. BART’s transmission contract rights on Pacific Gas and Electric’s network — which predate the existence of the ISO — are set to expire at the end of the year. Those rights will automatically convert to CAISO service, leaving the agency exposed to congestion charges.

A recognized LSE facing a similar circumstance can cover that exposure by seeking a free allocation of congestion revenue rights (CRRs) in the initial round of CAISO’s annual allocation process. In that case, the ISO would treat the expiring contract rights as if they were expiring annual CRRs.

Under current practice, BART is unable to seek that remedy because it does not meet the Tariff definition of an LSE.

For LSEs, the CRR benefit comes with a corresponding obligation: the need to procure enough resources to support their loads plus a reserve margin — the “resource adequacy” provision.

That requirement prompted unease for at least one ISO stakeholder — the Metropolitan Water District of Southern California. While the district is authorized to serve its own load, it currently relies on Southern California Edison to meet its energy needs under a long-term agreement.

During an Aug. 23 call to discuss the proposed definition change, a representative from the water district said his agency was concerned that it would face a resource adequacy obligation upon expiration of its transmission contract rights on SoCalEd’s system.

The latest draft attempts to address that concern by adjusting the language of the revised definition.

“The ISO clarified that an entity must be an end user, have the authority to serve its load through the wholesale purchase of power and choose to exercise its authority to serve its load through the wholesale purchase of power,” CAISO said.

The updated proposal addresses additional issues raised by market participants, including:

Clarifying that the proposed definition applies only to entities serving their own load through the purchase of energy, and not to those generating power on site for their own use;
Describing the CRR allocation impact under multiple scenarios related to entities with or without existing transmission contracts and ownership rights to demonstrate that there will be little or no impact to current CRR allocation participants; and
Removing the term “California” from the definition to include entities such as Nevada-based Valley Electric Association, an existing ISO member.

CAISO has scheduled a Sept. 21 call to discuss the proposal and plans to submit a final amendment for approval to the Board of Governors in late October.
