ISO-NE Capacity Prices Hit 5-Year Low

By Michael Kuser

Prices in ISO-NE’s Forward Capacity Auction sank to a five-year low on a surplus of available resources, the RTO said Thursday.

The preliminary clearing price in Tuesday’s 12th FCA for the 2021/22 commitment period dropped 13% to $4.63/kW-month, its lowest level since 2013. Last year’s auction cleared at $5.30.

Nearly 34,830 MW were acquired in the auction — 1,105 MW more than the target — at a cost of about $2.07 billion, putting the value of the auction $330 million below last year and about half the level of FCA 9.

Resources totaling 40,612 MW qualified to participate in the auction, including 35,007 MW of existing capacity and 206 new resources totaling 5,605 MW.

FERC accepted ISO-NE’s informational filing for FCA 12 last month, rejecting protests from CPower and Tesla, which sought to compel the RTO to re-evaluate the renewable technology resource designation for six solar projects, and from Efficiency Maine Trust, which challenged the methodology for calculating existing capacity qualification values. (See FERC OKs ISO-NE FCA 12 Filing; Rejects Protests.)

Zone by Zone

Like last year, the most recent auction saw the region divided into three zones: Northern New England (NNE), comprising Vermont, New Hampshire, and Maine; Southeast New England (SENE), composed of Southeastern Massachusetts, Rhode Island, Northeastern Massachusetts and Greater Boston; and Rest of Pool (ROP), made up of Connecticut and western and central Massachusetts. System planners modeled NNE as export-constrained and SENE as import-constrained.

Some existing resources dropped out during Tuesday’s auction when prices fell below the level needed to justify carrying the risks of a capacity supply obligation, prompting the RTO to conduct reliability reviews on about 2,775 MW seeking to delist.

The reviews indicated “that transmission lines in a particular sub-region could be overloaded in extreme summer weather, jeopardizing reliability, if about 1,300 MW of submitted delist bids were not available,” Robert Ethier, ISO-NE vice president of market operations, said in a statement. “The ISO will address that potential reliability risk by retaining the resources for the 2021-2022 capacity commitment period. All other delist bids, including other bids in that sub-region, were accepted.”

FCA 12 closed for most resources after four rounds of competitive bidding. The $4.63/kW-month clearing price will be paid to all resources in all three capacity zones in New England, 524 MW of imports from New York and 57 MW from one interconnection with Quebec.

Imports over two other interconnections from neighboring regions, Quebec and New Brunswick, continued into a fifth round, which closed at $3.70/kW-month for 442 MW from Quebec and $3.16/kW-month for 194 MW from New Brunswick.

New and Old

No new large generators cleared in the auction, but included in the 174 MW of new generation that did clear is a new 58-MW natural gas unit and 87 MW of increased generating capacity at some existing power plants, the RTO said.

ISO-NE also noted that 3,600 MW of energy-efficiency and demand-reduction measures cleared the auction, including 514 MW of new resources —the equivalent of a large power plant. Also clearing were 1,217 MW in total imports from New York, Quebec and New Brunswick.

In total, 132 MW of wind and 86 MW of solar facilities cleared FCA 12, including 1 MW of new wind and 21 MW of new solar facilities. Most photovoltaic resources in the region are on the distribution system and don’t participate in the wholesale markets.

Retirement bids that were submitted and accepted before FCA 12 totaled 511 MW of resources, including one large generator — the 383-MW Bridgeport Harbor 3 coal-fired unit. The RTO will file final auction results, including resource-specific information, with FERC later this month.

MISO Resource Adequacy Subcommittee Briefs: Feb. 7, 2018

CARMEL, Ind. — Preliminary estimates show that MISO’s capacity requirements and available supply for the 2018/19 Planning Resource Auction will be in line with last year’s figures.

MISO RASC resource adequacy — Bachus | © *RTO Insider*

MISO has been planning for a systemwide coincident peak load of nearly 122 GW, a zonal coincident peak of 126 GW and a planning reserve margin requirement of 135 GW since the beginning of the year, Tim Bachus, capacity market administration analyst, told the Resource Adequacy Subcommittee on Feb. 7. (See MISO RASC Briefs: Little Change to Capacity Forecasts.)

While the forecast is — so far — steady year-over-year, RTO staff are still reviewing the data and won’t present final numbers until March, Bachus said.

The RTO’s zonal predictions show a capacity surplus similar to last year’s capacity auction, with all zones having enough installed capacity to meet local clearing requirements:

Zone 1, covering Minnesota, the Dakotas and western Wisconsin, is forecast to have a 16.5-GW coincident peak forecast, an 18.4-GW planning reserve margin requirement and a 15.7-GW local clearing requirement. The region has 25.2 GW of total installed capacity.
Zone 2, covering eastern Wisconsin and Michigan’s Upper Peninsula, is predicted to have a 12.2-GW coincident peak, a 13.5-GW planning reserve margin requirement and a 12.7-GW local clearing requirement. The region has 15.4 GW worth of total installed capacity.
Zone 3 in Iowa and Zone 5 in Missouri (combined by MISO to keep pivotal suppliers’ information private) together have a 16.6-GW coincident peak forecast, with an 18.3-GW planning reserve margin requirement and a 14.4-GW local clearing requirement. The zones have just under 27 GW of total installed capacity.
Zone 4 in Illinois is expected to have a 9.1-GW coincident peak, a 10.1-GW planning reserve margin requirement and a 5.2-GW local clearing requirement. The zone has just under 14 GW worth of total installed capacity.
Zone 6, covering Indiana and Kentucky, so far has a 16.6-GW coincident peak forecast with an 18.6-GW planning reserve margin requirement and a 12.5-GW local clearing requirement. The zone has 20.4 GW worth of total installed capacity.
Zone 7 in Michigan’s Lower Peninsula is expected to peak at 19.9 GW, have a 22-GW planning reserve margin requirement and a 20.7-GW local clearing requirement. The region has nearly 25 GW in total installed capacity.
Zone 8 in Arkansas, Zone 9 in Louisiana and Texas and Zone 10 in Mississippi (also combined to protect utility information) are expected to have a nearly 31-GW coincident peak, a 34-GW planning reserve margin requirement and a 28.8-GW local clearing requirement. MISO South combined contains almost 42 GW in total installed capacity.

MISO will conduct its sixth annual PRA during the second week of April.

Scrapping Out-Year Import and Export Limit Estimates?

MISO is recommending that it discontinue its practice of making long-term predictions of capacity import and export limits, saying the results are too unreliable to be used in planning.

“Out-year results are volatile due to uncertainty around future generation dispatch. We don’t have a good picture of what these will be,” said MISO’s Matt Sutton.

MISO each year produces both near-term and long-term predictions for capacity import/export limits between zones to inform its loss-of-load expectation (LOLE) study.

After examining the out-year limits, MISO could not identify any processes that “rely upon these transfer values in resource planning,” Sutton said, adding that creating the forecasts no longer makes sense because the RTO cannot predict with certainty what resources will retire. Although MISO has been producing the long-term forecasts for about four years, no staff member at the meeting could say why they were proposed in the first place.

Customized Energy Solutions’ David Sapper disagreed with MISO’s view, saying there was value in seeing long-term predictions of decreases or increases.

“We might miss out,” agreed Consumers Energy’s Jeff Beattie.

WPPI Energy’s Steve Leovy also said he found value in the long-term predictions and never disparaged MISO for what he deemed to be expected volatility.

“We’ve been thinking about the value of this analysis and what it’s used for ever since a stakeholder comment last year on process improvements,” Sutton said.

CES’ Ted Kuhn asked if the volatility and uncertainty surrounding the process was “a stake in the heart” to any possible effort to conduct a three-year forward capacity market. Sutton said MISO would be forced to make such long-term predictions should it ever decide to adopt a three-year forward market design.

MISO will return to the RASC in March with a decision on whether to discontinue the long-term limit planning.

Possible End to LOLE Work Group

MISO is proposing to disband the Loss of Load Expectation Working Group (LOLEWG) and move its policy discussions into the RASC — but several stakeholders aren’t keen on the idea.

Laura Rauch, MISO resource adequacy manager, said the group has recently had light agendas, while its discussions frequently overlap those in the RASC.

“It’s about efficiency and making sure we have the right people in the room when we discuss policy,” she said.

The LOLEWG is responsible for reviewing and making recommendations about the methodology and assumptions that inform MISO’s annual LOLE study, which calculates planning reserve margin requirements for each load-serving entity.

American Electric Power’s Kent Feliks said he “cringed” at the thought of bringing the group’s technical discussions before a larger audience.

Other stakeholders asked about simply reducing its meetings. Rauch said MISO has already both reduced the number of meetings and shortened their duration.

Dynegy’s Mark Volpe said the LOLE study will face new challenges in the future, including accounting for external zones in the PRA and possible changes to MISO and PJM’s pseudo-tied generation rules. Other stakeholders said the LOLEWG also must work on adequately capturing and estimating MISO’s ever-evolving fuel mix.

“That’s new and unchartered waters,” Volpe said.

Rauch asked stakeholders to provide opinions on the fate of the LOLEWG by Feb. 20. The group is next scheduled to meet on March 6; the lone agenda item is discussion of MISO’s recommendation to sunset the group.

NERC Board Approves Dissolving SPP Regional Entity

By Tom Kleckner

FORT LAUDERDALE, Fla. — NERC’s Board of Trustees on Thursday voted to dissolve the SPP Regional Entity (RE) by terminating the RTO’s regional delegation agreement, ending a reliability oversight role that concerned both the reliability organization and FERC.

With the termination of the NERC-SPP delegation agreement, most of the RE’s 122 registered entities will be reassigned to the Midwest Reliability Organization (MRO), with the remainder joining SERC Reliability Corp. At the same time, NERC will take over compliance monitoring and enforcement of the RTO for two years following the dissolution’s effective date. SERC has been responsible for compliance monitoring and enforcement since 2010.

SPP CEO Nick Brown said he supported the trustees’ decision but was disappointed in NERC assuming SERC’s monitoring role. The RTO said it preferred having ReliabilityFirst take that responsibility. (See NERC Seeks to Oversee SPP Reliability Compliance.)

“Their decision to provide compliance enforcement services for two years was not what we hoped for, but we’re ready to move forward,” Brown said in a statement. “We look forward to working in the NERC arena to improve processes related to regional assignment and compliance monitoring and enforcement.”

NERC will determine a successor for SPP’s compliance monitoring and enforcement after completing its two years of oversight, said the organization’s interim CEO, Charles Berardesco.

SPP said last July that it would dissolve the RE, which is responsible for auditing and enforcing reliability rules in three balancing authorities: SPP, Southwestern Power Administration and parts of MISO. (See SPP to Dissolve Regional Entity.)

SPP was appointed by NERC as an RE in 2007, but Brown said last year it became clear that agreement was “in jeopardy” as the RE’s footprint did not grow to match the RTO’s current 14-state territory. NERC also expressed concerns about the relationship between SPP, the RE and the RTO’s corporate compliance responsibilities.

That dual role also caused problems with FERC, which criticized SPP in a 2008 audit for failing to ensure the RE’s independence from the RTO (PA08-2, AD09-3). The audit called for improved oversight from the RE Board of Trustees to prevent conflicts of interest.

The termination agreement is expected to be approved by MRO next week. Berardesco said the agency will then move “expeditiously” to file for FERC’s “prompt” approval, easing the RE’s concern that it will continue to hemorrhage its staff.

NERC staff said they plan to make the FERC filing as soon as early March. SPP hopes to complete the transition by the end of July.

“We all recognize as the SPP RE goes away, there is the potential for a gap with people leaving,” Berardesco said.

Ken McIntyre, NERC vice president and director of standards and compliance, reassured the trustees that the agency is working closely with the RE to stem further staff losses, saying, “We are closely aligned on the issues as we move forward.”

He said staff are already working on the filing and are only waiting on final approval from the MRO board. “We have every incentive to move forward as quickly as we can. That’s in the best interest of everyone involved.”

McIntyre also said staff have collaborated with MRO and SERC to “ensure a high level of continuity during and after the transfer occurs.”

“I believe the level of staffing they have requested is correct and necessary to handle the number of entities that are transitioning,” he said. “We are confident … that both REs are capable of handling the oversight of the entities in their regions.”

MRO and SERC are both adding staff — including some from the SPP RE — to handle their additional responsibilities. NERC will also provide the REs with additional support.

“Staff has been working with both entities regarding their new responsibilities,” McIntyre said. “We’ve told both entities we would be enhancing our oversight in the next few months, to help them do the work.”

Registered entities were reassigned without looking at RTO or market boundaries, McIntyre said. (See NERC Assigns SPP RE Registered Entities to MRO, SERC.) He told the trustees that incumbent MRO and SERC entities will see only a small increase in cost, if that.

NRG Selling Renewables, Other Assets for $2.8 Billion

By Peter Key

NRG Energy on Wednesday said it has agreed to sell several of its businesses in transactions that will bring the company $2.8 billion in cash and take $7 billion in debt off its books.

The deals, which NRG expects to close in the second half of the year, involve its renewables businesses, its interest in NRG Yield and its South Central Generating subsidiary.

The sales, which require numerous regulatory approvals, are part of the transformation plan that NRG launched last July in response to pressure from hedge fund Elliott Management and private investment firm Bluescape Energy Partners, which a year ago revealed they owned a 9.4% stake in NRG and said they believed its shares were “deeply undervalued and that there exist numerous opportunities to significantly increase shareholder value, including operational and financial improvements as well as strategic initiatives.”

NRG expects to announce more sales over the course of the year and is revising its total asset sales cash proceeds target under the plan to $3.2 billion.

Global Infrastructure Partners (GIP) agreed to buy NRG’s controlling stake and 46% interest in NRG Yield, as well as its renewable development and operations and maintenance businesses, for $1.375 billion in cash.

GIP is a $40 billion private equity fund that “makes equity investments in high quality infrastructure assets in the energy, transport and water/waste sectors where we possess deep experience and strong relationships,” according to the company’s website.

“We view each of the three acquired businesses — the [NRG Yield] stake, the O&M business and the development business — as highly complementary and well positioned to capitalize on the increasing market demand for low-cost, clean energy,” GIP Chairman Adebayo Ogunlesi said in a statement.

The sale is subject to antitrust review under the Hart-Scott-Rodino act and must be approved by FERC, the U.S. Department of Energy, the California Public Utilities Commission, the Connecticut Public Utilities Regulatory Authority and the Pennsylvania Public Utility Commission.

As part of the deal, NRG also has agreed to sell two assets to NRG Yield for about $407 million: the 527-MW Carlsbad Energy Center, a natural-gas fired power plant in Carlsbad, Calif., scheduled to come online by the end of the year, and the 154-MW Buckthorn Solar farm in Pecos County, Texas.

Additionally, NRG will sell its South Central business to Cleco Corporate Holdings for $1 billion in cash. The South Central unit owns and operates 3,555 MW in generation assets consisting of a 75% stake in the 300-MW Bayou Cove natural gas plant in Jennings, La.; the 430-MW Big Cajun-I natural gas plant in Jarreau, La.; the 1,461-MW Big Cajun-II coal and natural gas plant in New Roads, La.; the 1,263-MW Cottonwood natural gas plant in Deweyville, Texas; and the 176-MW Sterlington natural gas plant in Sterlington, La. NRG will lease back the Cottonwood plant through May 2025.

That sale is also subject to antitrust review and must be approved by FERC, the Committee on Foreign Investment in the United States and the Louisiana Public Service Commission.

Cleco Sees Big Growth from NRG Acquisition

Eric Schouest, vice president of marketing-South for Cleco Power, told the Gulf Coast Power Association’s MISO South regional conference in New Orleans on Thursday that his company’s acquisition includes full service wholesale power supply contracts for nine Louisiana cooperatives, five municipalities in Arkansas, Louisiana and Texas, and one investor-owned utility. “We serve about 23 of the 64 parishes in the state of Louisiana. It adds about 23, 24 new ones,” he said.

Environmentalists Push Back on Dynegy-backed Air Standard

By Amanda Durish Cook

Environmental groups have moved to halt an attempted roll-back of Illinois’ emissions standards, which would weaken pollution limits for Dynegy’s coal-fired generation fleet within the state.

The Environmental Defense Fund, Environmental Law and Policy Center (ELPC), Natural Resources Defense Council (NRDC), Sierra Club and Respiratory Health Association last week filed a joint motion to stop the Illinois Pollution Control Board from holding hearings on the proposed emissions rule change until Dynegy completes its merger with Vistra in late April. (See Vistra Energy Swallowing Dynegy in $1.7B Deal.)

The nonprofits argue that Vistra has so far been uninvolved with drafting the Multi-Pollutant Standard rulemaking and won’t be bound to “any of Dynegy’s statements about how it would operate the plants were the rule to be implemented.”

In their motion, the groups say, “It is unknown whether, in a few months’ time, the new owners will wish to pursue the current proposed rule modifications, maintain the current rule, or propose additional or different modifications…In several months…Dynegy will no longer be the decision-makers.”

The groups further contend that while Dynegy’s proposed pollutant rulemaking is predicated on its need for financial relief, the company’s financial picture will be sunnier after the merger.

“The resulting company will have over $4 billion in equity and face an entirely different financial situation, undercutting Dynegy’s main argument for the rule change,” the organizations claim.

Dynegy attorneys worked with the Illinois Environmental Protection Agency last year to revise the state’s 2006 clean air standard for coal plants. The company is seeking to replace the current rate-based emissions limits with an annual cap on sulfur dioxide and nitrogen oxide emissions for the state’s coal fleet as a whole. If approved, the new sulfur dioxide limit would be almost double what Dynegy emitted last year, while the nitrogen oxide cap would be 79% higher. Additionally, the caps would not decline should Dynegy retire or mothball any plants. (See “Illinois EPA Rule Change Still in the Works,” Dynegy Auction Proposal Fails to Gain Ill. Lawmaker Support.)

Dynegy says it will not waver in its pursuit of aggregate annual tonnage caps and contends that the hearings should continue as planned.

“Dynegy’s focus is on business as usual. As a result of anti-trust laws, we have to operate independently of Vistra Energy. We believe the established hearing process that’s being conducted by the Illinois Pollution Control Board should continue,” said Dynegy spokesman David Byford.

More than that, Byford argued, the motion is bad for business in the state.

“The motion by the environmentalists sets a bad precedent and will have a chilling effect on anyone doing business or considering doing business in Illinois. Any prudent owner will undertake a number of internal and external initiatives to help the plants’ viability, and evaluate each plant on a stand-alone basis, just as any business — large or small — would do,” he said in an email to RTO Insider.

Byford also contends that the Illinois EPA estimates that allowable sulfur dioxide emissions under the proposed rule would be 17% lower than under the current rule, while nitrogen oxide emissions would be 24% lower. But environmental groups have said the draft rule will permit overall emissions to exceed those of Dynegy’s fleet in the last two years, and some predict the company will shutter its more expensive coal plants with modern pollution controls, allowing cheaper plants without scrubbers to run.

The groups also argue the rulemaking stands to benefit a company that will soon cease to exist.

“This motion will ensure that Illinois doesn’t rush to change important pollution standards that protect the health and environment of Illinoisans only to help a company that will no longer be in existence by the middle of this year,” said NRDC staff attorney Toba Pearlman.

“The Illinois Environmental Protection Agency has been talking to the wrong company. It’s time to put an end to this poorly conceived, backroom proposal to boost profits at the expense of public health,” said ELPC staff attorney Lindsay Dubin.

The Pollution Control Board held one hearing on the proposed rule change in Peoria last month, and has scheduled another for March 6 in Edwardsville.

Peak, PJM Pitch ‘Marketplace for the West’

By Jason Fordney

Peak Reliability and PJM Connext on Tuesday refined their pitch to attract participants to a new Western energy market, saying they envision “a marketplace built by and for the West.”

“We sense, and we have heard, some people saying it’s coming down to the time for some choice in markets in the West again,” PJM Connext’s Fran Barrett said during a Feb. 6 meeting and conference call hosted by Peak. He added that PJM is “heavily, heavily focused on the bottom line.”

Barrett emphasized PJM’s experience operating a 13-state market in the East, and indicated a focus on reliability, self-governance and providing options for various market structures for potential participants. Officials from the organizations provided more detail on how the new Peak/PJM market would coordinate with other market and non-market areas, including possible congestion management practices.

Peak and PJM Connext this week outlined how their proposed market would coordinate with other market and non-market areas.

Peak and PJM first described their joint market initiative in January. (See Peak, PJM Detail Western Market Proposal.) In a presentation Tuesday, they laid out three possible market options “customized to the needs of participants,” each of which includes a nodal real-time market, day-ahead market, financial transmission rights, integrated settlement and credit management. Settlement would be based on PJM’s structure, modified for the West, with a central counter-party structure and weekly billing.

Interregional Coordination Proposed

Peak and PJM also provided more detail about how their proposed market would coordinate with other areas in the West. Their goal is to implement the market in two phases, the first using an “enhanced curtailment calculator” tool in a process comparable to the transmission loading relief procedure used in the Eastern Interconnection.

pjm connext western energy market peak reliability — Peak Reliability/PJM Connext Proposal for Inter-Regional Coordination | *PJM Connext, Peak Reliability*

A second “market-to-market” phase would be more complex and similar to how PJM conducts coordination with MISO and NYISO. In those cases, the RTOs use combined redispatch as a joint congestion management tool for greater efficiency, and costs are allocated between RTOs based on transmission flows and negotiated historical rights.

Barrett said Peak and PJM did not know exactly what minimum size footprint or configuration would be necessary to make the proposal work, noting they were gathering data to study the issue.

“We haven’t modeled in the Swiss cheese or the string cheese or if we will have people all over the place,” Barrett said, describing the possible variable shapes of the market’s footprint.

CAISO recently announced it will depart Peak, become its own reliability coordinator and offer to migrate Peak’s current members. (See CAISO Bid for Western RTO to Face Competition in 2018.)

NYC, Goals Dominate Talk on Carbon Pricing

By Michael Kuser

RENSSELAER, N.Y. — New York’s Integrating Public Policy Task Force (IPPTF) hit resistance on the first paragraph when it unveiled its final work plan for pricing carbon into the state’s wholesale electricity on Monday.

That section sets out the plan’s intended purpose: to explore incorporating the costs of carbon into the market while “providing the greatest benefits at the least cost to consumers.”

Several stakeholders at the Feb. 5 meeting sought a clearer definition of “benefits,” while others wanted to know why the plan would focus primarily on benefits to consumers. In addition, some expressed concerns about how carbon pricing would translate into actual carbon reductions, given existing constraints within the state.

The IPPTF is a joint effort of NYISO and the state’s Department of Public Service (17-01821). The group’s latest plan includes five issue tracks, reduced from six: 1) straw proposal development; 2) wholesale energy market mechanics (including “carbon leakage” and how to measure emissions) and interaction with other wholesale market processes; 3) policy mechanics, such as setting the carbon charge; 4) interaction with other state policies; and 5) customer impacts. (See New York Stakeholders Debate Carbon Policy ‘Issue Tracks’.)

Energy Market Primer

IPPTF co-chair Marco Padula, DPS deputy director for market structure, clarified that the group wasn’t created to review the contents of the state’s Clean Energy Standard but to achieve the objectives set out in the rule — namely, that 50% of New York’s electricity come from renewable energy sources by 2030.

Padula said the task force should work out the details of each track over the course of the year, as it posts reports from each meeting along with stakeholder comments. The task force will meet nearly every Monday to work through the tracks and plans to develop preliminary proposals by early August to deliver a unified proposal by December.

Erin Hogan, of the DPS Utility Intervention Unit, said the task force needs to better understand what goal is being discussed because state policy calls for 50% of the target to be met by energy efficiency measures, meaning “that renewables needed afterwards would be less.”

In the near future, stakeholders “should perhaps have a primer, maybe a little presentation just to level what exactly we’re talking about, so we don’t tie ourselves up in knots in the middle of meetings without having that level of understanding what the goals really are,” Hogan said.

Representing a coalition of large industrial, commercial and institutional energy customers, Couch White attorney Michael Mager reminded the task force of a key goal of the exercise.

“I don’t care whether you get to it now or when we get to the last track,” Mager said. “At the last meeting … there was some agreement in the room that, in addition to price impacts, we should also be measuring exactly what carbon abatement would be taking place. It doesn’t seem to have been reflected in the work plan, [which] still kind of limits the last track to customer impacts. It doesn’t seem to address anywhere actually measuring whether we’d be reducing carbon emissions at all.”

The Transmission-Emissions Nexus

The predicament of New York’s biggest metro area loomed large during the meeting. Ron Minsk, a consultant to New York City, delivered a presentation that emphasized the need for a new transmission to deliver renewable energy to the state’s largest load center. With a peak load of more than 11,500 MW, the city accounts for approximately 30% of the state’s load. The downstate region, including Long Island, represents about 50%. Minsk’s presentation echoed comments the city filed with the task force in January.

“We don’t want to end up having an approach where we have renewables displacing other renewables,” Minsk said. “So this gets to the transmission issues, which the city has expressed concern about before. It goes to that submission, making sure that the benefits are widely distributed. … Even with new transmission projects that are already on the books, there are transmission constraints that keep upstate power from getting downstate.”

The upstate grid is already pretty clean, with about 85% of generation carbon free, he said.

“In order to meet the state’s goals, you’re going to have to get more renewable power downstate, and, in order to do that, you have to relieve transmission,” Minsk said.

The city’s comments pointed out that NYISO has already drawn a similar conclusion, noting that even if the state adds the desired quantity of new renewables by 2030, it will not realize their full benefits without new transmission or local storage resources — or if renewable development occurs far from load centers.

Mark Younger of Hudson Energy Economics said more renewable generation will provide no consumer benefits whatsoever if it’s built in the wrong location.

“Maybe the proper way to look at it is how are you getting the cheapest dollar per ton reduction, considering that to serve New York City and the southern area, [either] you’re … paying directly for generation there or you’re paying for generation somewhere else and the infrastructure that’s necessary to get there,” Younger said.

The transmission infrastructure is part of the price of achieving the desired carbon reduction, he said.

“You can’t ignore that infrastructure because … it looks very cheap to build all your renewable resources far away, but then incur billions of dollars that you don’t recognize as part of that decision to build the resources far away,” Younger said.

The task force next meets Feb. 12 at NYISO headquarters.

Hartburg-Sabine Tx Project Open for Bids

By Amanda Durish Cook

MISO on Tuesday opened a bidding window for its second-ever competitive transmission solicitation, a process required under FERC Order 1000.

Developers will be eligible to bid on the $130 million, 500-kV Hartburg-Sabine Junction project in eastern Texas until July 20. The congestion-relieving line and substation are slated to be in service by June 1, 2023.

MISO’s Board of Directors last week granted late approval for the project under the RTO’s 2017 Transmission Expansion Plan. (See MISO Board Approves Texas Competitive Tx Project.) MISO expects to select a developer by the end of the year and post a full report on its evaluation no later than Jan. 30, 2019.

“When completed, this project will help bring economic benefits to a transmission-constrained area of Texas,” said Kent Fonvielle, executive director for MISO’s South region.

MISO will judge the proposals based on weighted criteria, which include cost and design, project implementation, operations and maintenance, and participation in the planning process. The RTO has revealed that 11 potential developers will already receive the 5% planning participation credit for suggesting the Hartburg-Sabine project in MISO’s annual Market Congestion Planning Study. They include Ameren Transmission Company of Illinois, Duke-American Transmission Co., East Texas Electric Cooperative, Entergy Texas, Grid America, ITC Holdings, Midcontinent MCN, Midwest Power Transmission Arkansas, NextEra Energy Transmission, Transource Energy and Xcel Energy.

Each proposal requires a $100,000 fee before MISO will begin considerations.

Prospective developers are required to communicate about the project using MISO’s TDQS@misoenergy.org email address and are instructed not to contact any RTO personnel directly. As with its first competitive transmission project in 2016, MISO will publicly post all developer questions and any answers it can provide on its competitive administration webpage. MISO will accept questions about the request for proposals until June 25 and will hold three informational meetings by conference call on Feb. 27, April 9 and May 29.

MISO has redacted some critical energy infrastructure information from the public version of its RFP, including interconnection requirements, some of Entergy’s local planning criteria, the coordinates of the new substation and aerial views of existing lines in the area.

CAISO Sees 2017 Revenue Boost

By Jason Fordney

CAISO’s operating revenues jumped 4.4% to $214 million last year on the back of increased Energy Imbalance Market (EIM) earnings and an uptick in summer activity.

The ISO reported “true operating income” (operating revenue minus operating expenses) of $47.4 million for the full year, compared with $44.4 million in 2016. True operating income fluctuates throughout the year as a large portion of revenue comes in the summer, when energy demand and prices are higher.

CAISO is a nonprofit corporation that earns the bulk of its revenue from a grid management charge (GMC), composed of market services, system operations and congestion revenue rights charges assessed by the megawatt-hour. The ISO also collects other charges and fees, including those for trades between scheduling coordinators. It additionally operates the EIM.

Including depreciation and amortization, CAISO’s fourth-quarter rep o rt showed a $6.9 million net operating income “loss,” but spokesman Steven Greenlee said that is “merely an accounting outcome.”

“The level of net operating income has no effect on our cash flow, budgeting or grid management charges,” Greenlee told RTO Insider.

CAISO collected $47.3 million of its operating revenue from its GMC in the fourth quarter, up from about $45.8 million the previous year. Other operating revenues totaled $4 million during the last quarter. GMC revenue for 2017 grew by 3% to $198.3 million and was higher than what CAISO had budgeted.

August Sees Highest Take

CAISO’s gross market revenues for all services going through the ISO market peaked at $1.2 billion in August, the period of highest summer demand and when the ISO dealt with the impact of the solar eclipse on solar generation. (See Grid O perators Manage Solar Eclipse.) Revenues fell to their lowest in February, at slightly more than $500 million.

The gross revenue figure represents the total value of all energy transactions and related services included on ISO invoices. CAISO recoups its costs through the GMC, which is a small component of these overall market revenues, the ISO said.

Q4 Expenses Grow

The ISO’s fourth-quarter operating expenses were $51 million, up about 16% from the same period a year earlier. Expenses include salaries and benefits to employees, building and facility costs, insurance, outside contractors, legal and auditing services, training, travel and professional dues.

CAISO’s expenditures for consulting and contracting services grew by $2.9 million quarter-over-quarter to $7.2 million. Third-party vendor contracts rose from $2.6 million to $3.5 million between the same two periods.

While expenses grew, they were $7.1 million less than CAISO had budgeted for the year. The ISO cut salaries and wages by about $1 million quarter-over-quarter and had lower “building, leases and facilities” costs, and lower legal and auditing expenses. The ISO cut three full-time positions in 2017, leaving the headcount at 599.

Revenue Exceeds Budgeted Level

Fourth-quarter operating revenues exceeded the budget by $7.5 million, mostly because of EIM administrative charges and forecasting fees beating projections, the ISO said.

CAISO’s Corporate Management Committee approved $19.5 million in projects last year to increase electric system performance and to meet FERC mandates, the ISO said. These include market improvements, technology, customer service, grid readiness and other funds.

The ISO on Jan. 3 had $1.9 billion in collateral from market participants to support $294 million in aggregate liabilities in the market.

SPP FERC Briefs: Week of Feb. 6, 2018

FERC approved an SPP waiver request that allows the RTO to forego performing standalone evaluations in favor of a time-saving cluster scenario for three generator interconnection study groups (ER18-421).

The RTO asked for a limited waiver of its Tariff to enable it to expedite interconnection study requests in its Definitive Interconnection System Impact Study (DISIS) queue, which evaluates the effect of proposed generators on transmission system reliability. The request was limited to three DISIS clusters: DISIS-2016-002, DISIS-2017-001 and DISIS-2017-002.

SPP said the standalone scenario has proven costly, requiring significant time and resources to perform while providing minimal value to interconnection customers. The RTO noted standalone results are informational and not binding, unlike the cluster scenario’s results, and said that as the size of its queue continues to grow, the standalone will become less valuable.

The RTO told FERC it intends to revise its Tariff to eliminate the standalone evaluation and will make the base case study models available earlier in the study process, allowing interconnection customers to perform their own standalone analysis. Several generation developers said their concerns about the loss of information from the standalone scenario would be mitigated by accessing the base case study models earlier, SPP said.

NextEra Energy Resources, Westar Energy, Sunflower Electric Power and Mid-Kansas Electric intervened in the proceeding.

SPP Granted Waiver Request to Resolve Billing Dispute

The commission granted a second SPP waiver request to help resolve a billing dispute over approximately $175,000 in transmission charges and penalties with Missouri’s Carthage Electric & Water Plant (ER18-385).

SPP filed the request with the commission in December, along with revised transmission service agreements showing Carthage as the customer and the Southwestern Power Administration as the host transmission owner. The agreements included terms and conditions that did not conform to the RTO’s Tariff, but they were included to implement the results of SPP’s dispute resolution process related to Carthage’s unreserved use of the transmission system.

The RTO said the agreements were intended to correct errors “made in good faith” and limited to only penalty amounts assessed to Carthage for instances of unreserved use between March 2014, when SPP’s Integrated Marketplace came online, through February 2015. SPP said its billing process was delayed because of changes made in implementing the new markets.

FERC found the revised agreements’ nonconforming changes “appropriately reflect” SPP’s dispute resolution process, enabled the RTO to resolve the billing dispute and will not “lead to undesirable consequences, such as harming third parties.”

MRES Escapes Obligation for QF Purchases

FERC approved a request by Missouri River Energy Services to terminate a mandatory obligation to purchase electric energy or capacity from qualifying facilities within SPP’s footprint and with a net capacity larger than 20 MW (QM18-2).

MRES, an organization of 60 member municipalities that own and operate their own electric distribution systems, made the request on behalf of itself and 33 of its members, which are all SPP members. It said QFs within SPP have nondiscriminatory access to a market that satisfies the requirements of the Public Utility Regulatory Policies Act and warrants termination of a utility’s mandatory purchase obligation under the act.

The commission agreed, rejecting a protest from a wind farm developer as being outside the proceeding’s scope. FERC said the protest did not rebut MRES’ application by showing factors unique to individual QFs, such as operational characteristics and transmission limitations that prevent them from having nondiscriminatory access to markets.

Tri-County CEO Loses Bid to Serve on 2 Boards

The commission denied a rehearing request from a utility CEO prohibited from serving on the boards of directors for both South Central MCN and Golden Spread Electric Cooperative (ID-8117).

FERC denied Zac Perkins, who has served as Tri-County Electric Cooperative’s CEO since May 2016, from holding the interlocking positions in April 2017. He claimed a position on the Golden Spread board by virtue of being a CEO at one of its distribution co-op members, and he said a long-term agreement between South Central and Tri-County entitled him to serve as the co-op’s designated board member with South Central.

The commission said it “generally disfavors” interlocks between two or more unaffiliated public utilities, and that Perkins’ justifications did not distinguish themselves from Federal Power Act’s rules intended to curb corporate relationships.

Perkins said FERC did not satisfactorily explain why its findings were appropriate and did not substantively address the arguments in his application. He said no public or private interests would be adversely affected by his holding interlocking board positions.

The commission disagreed, saying his arguments did not overcome its “well-documented concerns” about interlocks among unaffiliated public utilities and the “arm’s-length bargaining process” that could adversely affect competition and consumers.

Both South Central and Golden Spread are SPP members.
