FERC on Thursday denied Dominion Resources’ request for rehearing of an order rejecting its challenge to ISO-NE’s 2016 Forward Capacity Auction over a paperwork error that excluded capacity from its generating plant in Providence, R.I. (EL16-38-001).
Manchester Street Station | Dominion
The commission on May 2 denied most of Dominion’s February complaint about ISO-NE’s decision to block new incremental capacity from an upgrade to the company’s Manchester Street Station from participating in FCA 10 in February. The three-unit generator boosted its summer capacity by 21 MW to 477 MW.
In September 2015, ISO-NE approved the additional 21 MW for the auction. But the RTO later disqualified the additional capacity because Dominion failed to submit a “composite offer” linking the new capacity and the existing capacity at the plant.
The deadline for composite offers was Oct. 9, 2015. Dominion filed its complaint with FERC just days before the FCA in February.
The commission rejected the complaint in May, finding that the company had received adequate notice of the RTO’s filing requirements in October and November. The commission directed ISO-NE to revise its Tariff to provide greater clarity but denied Dominion’s request to resettle the auction as if the company’s additional capacity had participated.
“We are not persuaded by Dominion’s assertion that the commission erred in determining that ISO-NE did not violate its Tariff and was therefore mistaken in finding that resettlement was not required,” FERC wrote last week. “It would be contradictory to find that ISO-NE’s Tariff was unjust and unreasonable because it failed to provide notice of the filed rate, while also finding that ISO-NE violated the filed rate.”
FERC’s May order did find that ISO-NE’s tariff was “unclear regarding the process for new incremental generating capacity and existing generating capacity at the same resource to participate in the FCA.”
ISO-NE responded with proposed Tariff changes under which it would automatically match new summer incremental generating capacity with excess existing winter qualified capacity at the same resource.
But the commission ordered the RTO on Aug. 30 to further amend its Tariff to automatically match new winter incremental capacity with excess existing summer qualified capacity at the same resource. “We find that there is no reason to limit, based on season, the automatic matching of new capacity with excess existing capacity,” the commission said (ER16-2126).
ISO-NE’s second compliance filing is due by the end of October.
FERC Chairman Norman Bay announced the departure of his chief of staff, Larry Gasteiger, last week at the commission’s open meeting.
Gasteiger, whose last day was Friday, will take the role of Public Service Enterprise Group’s chief of federal regulatory policy. He worked at FERC for 19 years, including as Bay’s deputy director at the Office of Enforcement.
“I am personally grateful to Larry for the help he has given me over the years,” Bay said. He called Gasteiger “clearly one of the most important picks I had to make when I came in as the director of [Enforcement], when I was new to FERC and I was in great need of having a Sherpa.” Bay named Jamie Simler, current director of the Office of Energy Market Regulation, as Gasteiger’s replacement.
Energy Department Plans to Build Experimental Carbon Dioxide Plant
| Energy.gov
The Department of Energy is providing $80 million to build an experimental 10-MW power plant in San Antonio that will use carbon dioxide instead of steam to generate power.
Gas Technology Institute will lead the pilot project with Southwest Research Institute serving as an equal partner. General Electric’s Global Research team will also be involved.
EPA has not properly estimated job losses in the coal industry resulting from the Clean Air Act, a federal judge ruled last week.
The District Court for the Northern District of West Virginia ruled in favor of coal mining company Murray Energy, finding EPA has a “nondiscretionary duty” to track potential job losses and employment shifts from regulations written under the act.
“With specific statutory provisions like Section 321(a), Congress unmistakably intended to track and monitor the effects of the Clean Air Act and its implementing regulations on employment in order to improve the legislative and regulatory processes,” the opinion said.
Plaintiffs to Refile Lawsuit Blaming Fracking Industry for Earthquakes
Lawyers for two Oklahoma women will refile in state court a class action lawsuit that blames the fracking industry for the state’s recent spate of earthquakes.
The plaintiffs previously filed the suit in state court, but Devon Energy removed it to federal court under the Class Action Fairness Act of 2005, prompting them to agree to a voluntary dismissal.
The plaintiffs are required by law to wait one year to refile.
House Committee Investigating WAPA Security Breaches
A House of Representatives committee has asked the Western Area Power Administration to turn over documents by Nov. 1 relating to security breaches at the Liberty substation in Arizona.
The document request is part of the House Committee on Oversight and Government Reform’s investigation spurred by a July 14 Wall Street Journal article describing physical intrusions at the substation, including one in which its control room was ransacked.
There have been no arrests, and security cameras mostly weren’t working.
Interior Secretary Supports Klamath River Dam Removal
Secretary of Interior Sally Jewell sent a letter last week to FERC urging it to approve applications by PacifiCorp and Klamath River Renewal Corp. to remove four hydroelectric dams on the Klamath River.
PacifiCorp owns the dams, and Klamath River Renewal — a consortium of federal, state, tribal and local officials — wants to take ownership for the purpose of demolition.
In a measure that’s considered mostly symbolic, county voters will have the opportunity to vote on Nov. 8 as to whether the dams should be removed.
FERC last week approved a $154.8 million 2017 budget for NERC, its eight Regional Entities and the Western Interconnection Regional Advisory Body (WIRAB) (RR16-6).
The spending plan includes $54.3 million for NERC, $99.7 million for the Regional Entities and almost $760,000 for WIRAB, which was created by Western governors to advise FERC, NERC and the West’s RE, the Western Electricity Coordinating Council.
NERC’s budget will increase 3.6% over 2016, while its workforce drops to about 190 full-time equivalents.
Democrats, Republican Call for Full Disclosure of APS Election Spending
Two Democrats on November’s ballot for seats on the state’s Corporation Commission have aligned themselves with a Republican incumbent in calling for full disclosure by Arizona Public Service as to whether it spent money on the 2014 elections.
Democrats Bill Mundell and Tom Chabin called for an end to “a culture of corruption” and cited alleged personal meetings between Gary Pierce, a former commissioner, and Don Brandt, president and CEO of APS and its parent company.
APS is suing Republican incumbent Robert Burns over his position to force it to make full disclosure. Notwithstanding, Brandt’s company is supporting Burns’ bid for re-election, according to an email Brandt sent to company employees last week.
SoCalEd Proposal Addresses Corona’s Dwindling Electric Supply
Southern California Edison engineers and city officials met with Corona residents last week regarding a proposal to build 5 miles of medium-voltage power lines to address the region’s dwindling electric supply — with one area using 92% of its energy production potential last year.
The proposal calls for primarily above-ground lines, including a 66-kV transmission line carrying power to a new substation. It also includes above-ground transmission lines that would bisect the city’s center.
Construction could begin by 2019, with the lines becoming operational by 2012, according to SoCalEd’s website.
Jacumba Solar Approved to Build Solar Plant in San Diego County
Jacumba Solar last week received approval for a permit to build a 108-acre solar plant in Jacumba, near San Diego Gas & Electric’s East County Substation.
The plant will use a little more than 81,000 photovoltaic panels on roughly 2,200 fixed, tilted racks to generate 22 MW, which it will deliver to SDG&E’s substation through a 1,500-foot-long overhead transmission line, a press release from the San Diego County Board of Supervisors said.
County staff and proponents of the project said it would help the region meet state goals of producing one-half of all electricity from renewable sources by 2030 and cut greenhouse gas emissions.
San Diego, SunEdison Tentatively Extend Solar Panel Agreement
An October 2015 agreement between San Diego and SunEdison for installation of banks of solar panels at 25 sites across the city has been tentatively extended to at least April 2017, and possibly to June 2017, after the company failed to install a single panel. The original agreement called for installation of the first solar panels by last month.
SunEdison declared bankruptcy two months before it was supposed to begin construction and sought an extension for the first batch of projects. In July, city officials formally terminated the agreement’s initial five projects.
The city declined to release the new agreement, stating that it has not yet been formally approved, but it said SunEdison agreed to compensate it for opportunity costs related to the delay.
CAISO Flexible Ramping Product Delayed Until Nov. 1
FERC last week granted CAISO’s request to postpone the start date for implementing the ISO’s flexible ramping product until Nov. 1 — one month later than the original start date (ER16-2023).
CAISO last month petitioned to delay the effective date because it did not learn of the commission’s approval of the product until hours after a conference call scheduled to confirm the roll-out to market participants.
The new market mechanism is designed to improve real-time integration of the increasing amount of variable renewable energy resources coming on to the ISO’s system. The product will also be incorporated into the ISO-run Energy Imbalance Market.
UI Customers, Environmentalists Urge Distribution Rate Reduction
While The United Illuminating Co. seeks a distribution rate increase, 16 environmental and consumer groups are urging state regulators to reduce the current fixed-rate charge of $17.25/month its customers currently pay.
In a letter to the Public Utilities Regulatory Authority, the groups noted that the monthly charge is the highest of any investor-owned electric utility in New England and urged PURA to cut it by $6 to $8/month.
Distribution charges account for 27 cents of every dollar that UI customers pay for their electricity, UI spokesman Michael West said. He said the charge allows UI to provide the level of reliability its customers have come to expect.
State Senators Continue to Push For Legislation to Save Exelon Plants
State senators are continuing to look for ways to prevent Exelon from shuttering it Clinton Power Station and Quad Cities Generating Station nuclear power plants during the next two years.
Exelon lost $800 million on the two plants over the past seven years and announced it would close the plants after state lawmakers ended their spring legislative session without approving its proposed “Next Generation Energy Plan.”
Sponsors of the legislation have been negotiating with Exelon and other interested groups, and Sen. Donne Trotter, a Democrat, said he plans to use the General Assembly’s fall veto session to continue pushing legislation when lawmakers return on Nov. 15.
State regulators last week warned that the proposed $12.2 billion sale of Westar Energy to Great Plains Energy is in jeopardy if the companies don’t supply additional information regarding operational savings, and what departments or functions would remain in Topeka and for how long.
The Corporation Commission said in an order that its staff or the Citizens’ Utility Ratepayer Board could file for relief — which could include asking for dismissal of the merger application — if they maintain that the joint application does not adequately address the agency’s merger standards.
Chuck Caisley, a spokesman for GPE and Westar, said the companies were evaluating the order and are committed to closing the transaction in the spring of 2017 as planned.
Downtown Baton Rouge now has 10 electric car charging stations, and city-parish leaders hope to have 50 stations soon as part of their effort to lure green business.
Previously, the only electric car charging stations were near Louisiana State University and in south Baton Rouge.
Entergy gave a $75,000 grant for purchase and installation of the stations.
Stakeholders Clash over Proposal to Phase out Financial Incentives for Solar
LePage
A proposal to phase out financial incentives for homeowners using solar panels caused a clash of viewpoints last week at a hearing before the state’s Public Utilities Commission.
Residents and small-business owners said the proposal — which seeks to grandfather net-metering credits for current solar homeowners for 15 years and gradually reduce benefits for new solar owners over 10 years — would stifle solar energy’s growth and already is reducing the number of installations. Representatives from utilities, government and consumer affairs testified that the current financial incentives for rooftop solar hurt other ratepayers.
Last spring, the Legislature passed a compromise solar bill following a yearlong study and negotiations among stakeholders, but it was two votes shy of overriding a veto by Gov. Paul LePage.
Lincoln is purchasing its first electric car for about $22,000, along with dual plug-in electric charging stations for privately owned electric vehicles for nine downtown garages. Some of the funds will come from a state grant.
There are currently 67 electric vehicles registered in Lancaster County, but the group that spearheaded the grant hopes the new charging stations will encourage more electric car purchases.
300 Electric Vehicle Charging Stations Coming to Public Locations
Cuomo
Gov. Andrew Cuomo announced last week a five-year New York Power Authority contract for the installation of 300 electric vehicle charging stations at public locations across the state.
The agreement supports the governor’s ChargeNY Program, which aims for 3,000 charging stations online in the state by 2018.
It also is an important step in accomplishing the state’s goal to reduce greenhouse gas emissions 40% by 2030 from 1990 levels and ensure 50% of electricity consumed comes from renewable energy sources by 2030.
NYISO Report Finds Two Localized Transmission Security Reliability Needs
A new NYISO report found two localized transmission security reliability needs that will begin in 2017 — involving New York State Electric and Gas’ Oakdale 345/115-kV transformer and Long Island Power Authority’s East Garden City-Valley Stream 138-kV line — that require remedial action soon.
The ISO said in a press release that it will consider transmission plan updates from the transmission owners and then, if necessary, issue a solicitation for market-based and regulated solutions.
NYISO’s 2016 Reliability Needs Assessment report also found that the state’s bulk power system has adequate power generation resources to meet reliability needs for the next decade.
Feds Plans to Auction Gas Lease Rights for Wayne National Forest
The federal government gave notice last week that it is planning an online auction for Dec. 13 for oil and gas lease rights for Wayne National Forest, which could lead to fracking on public land.
Opponents have 30 days to file a formal protest.
The land is located in the far eastern part of the forest, where there are substantial oil and gas reserves and less opposition to energy drilling.
Commission Recommends Taxpayer-Funded Solar Incentives
The Public Utility Commission voted last week to pass a recommendation to the Legislature that it consider adopting taxpayer-funded incentives for solar energy programs that all residents can benefit from, regardless of their utility provider.
The state already has several taxpayer-funded programs intended to encourage solar energy development, but some of the incentives are scheduled to end soon. There also are a small number of ratepayer-funded programs, for which customers of specific utilities pay.
The commission noted that calculating the benefits and costs of each program is difficult because projects and customers are often eligible for more than one incentive program.
FirstEnergy Rate Case Settlements to Increase Residential Rates
FirstEnergy’s utilities filed distribution rate case settlement agreements with state regulators last week that, if approved, would result in rate increases for residential customers.
Met-Ed customers would see an average increase of 10.7%; Penelec customers 12.8%. Penn Power 10.4%; and West Penn Power 7.2%.
The state Public Utilities Commission is expected to issue final orders on the agreements and new rates on or before Jan. 26, 2017. Pursuant to the agreement, the utilities would not file for additional distribution base rate increases in the state until January 2019 at the earliest.
Dominion Required to Increase Water Monitoring at Possum Point
As Dominion Resources works to drain and consolidate five coal ash ponds at its Possum Point Power Station in Dumfries, state regulators are demanding that it install nine additional wells on the property and test water samples from monitoring wells on a biweekly basis.
Two of the nine additional wells will be monitoring wells installed near the property’s perimeter and may help detect whether groundwater from Dominion’s coal ash ponds is flowing toward nearby residential wells and contaminating drinking water.
Dominion is hoping to receive a solid waste permit so that it can move all its coal ash into one pond and bury it beneath two feet of soil.
Grassroots Effort Opposes Pipeline Extension in Eastern Panhandle
A grassroots effort is growing against a proposal by Mountaineer Gas Company of West Virginia to extend its natural gas distribution line by 56 miles in the Eastern Panhandle.
If approved by regulators, the pipeline project, slated to begin in 2018, would pass through Berkeley, Jefferson and Morgan counties, using buried lines 6 to 12 inches in diameter.
The state’s Public Service Commission has received 70 letters in opposition, said Russell J. Mokhiber, of Morgan County USA blog, who conducted an opposition meeting last week and distributed fliers saying “just say no to the gas pipeline.”
Judge to Decide Fate of Badger-Coulee Power Line Project
A La Crosse County judge will decide the fate of a 180-mile 345-kV transmission line from the La Crosse to Madison areas.
American Transmission Co. and Xcel Energy developed the Badger-Coulee Transmission Line project in 2010, and the Public Service Commission approved it in 2015.
The Town of Holland maintains that the commission did not legally approve the project — estimated to cost about $580 million — because it did not establish a need for it.
MISO announced on Friday it had changed four elements of its proposed forward capacity auction, prompting renewed calls from some stakeholders to delay a FERC filing planned for Nov. 1.
RTO officials — who described the changes as a “refinement” to a “limited set of design elements” — insisted the filing will be made as scheduled.
On an Oct. 21 Resource Adequacy Subcommittee conference call, MISO revealed it had adopted the Independent Market Monitor’s suggestion to incorporate a pivotal supplier test in the forward auction for the RTO’s retail-choice regions.
Officials also said they will include a three-year forward peak load contribution calculation and modify the design’s materiality test, congestion calculation and cost allocation.
Pivotal Supplier Test
The pivotal supplier test would allow the Monitor to identify resources inside or outside MISO’s footprint that are large enough to affect market outcomes. Suppliers identified as pivotal would be subject to the RTO’s existing physical and economic withholding provisions.
Dynegy’s Mark Volpe said that while the Monitor “should certainly suggest marketing monitoring measures,” the pivotal supplier test had not been explored in the stakeholder process and was not simply a “tweak.” He asked for a conference call with the Monitor prior to Nov. 1 to discuss the test. MISO staff said that was unlikely to happen.
Congestion Charges
Under other changes, MISO would allocate congestion charges resulting from the clearing of infeasible resources to buyers rather than sellers as originally proposed. Officials said the change was made to avoid discouraging sellers’ participation in the auction and to align the cost allocation with other FERC-approved capacity markets.
The RTO also said it will limit congestion charges in the forward auction to situations in which constraint changes lead to a less than one-day-in-five-years loss-of-load expectation. MISO’s prior draft allowed congestion charges to occur anytime a locational constraint binds and proved more restrictive under the forward auction than the prompt Planning Resource Auction. The change will maintain the relationship between the variable reliability target and the quantity of capacity procured for competitive retail demand, MISO said.
Consumers Energy’s Jeff Beattie noted that MISO’s retail-choice areas are “heavily interconnected” and said he doubted the new cost allocation would ever occur.
Jeff Bladen, executive director of MISO market services, agreed that new congestion costs would only occur under “extreme circumstances” when incremental resources are need to step in for megawatts that cannot be delivered.
“In a sense, it’s a replacement charge because the constraints modeled need to be changed,” Bladen said. He said the charge is needed because MISO “can’t guarantee feasibility three years into the future.” He noted that ISO-NE, NYISO and PJM use a similar method.
Peak Load Contribution
The addition of a peak load contribution calculation was intended to “alleviate retail customer risk from their purchase/offer obligations” in the forward auction against any PLC changes that take place in the PRA, MISO said.
Bladen said the PLC provides “equal footing between demand and supply resources that enter into the forward auction.”
Materiality Test
The materiality threshold determines whether local resource zones will be included in the forward auction. It will be used in Michigan and Wisconsin, where the zonal boundaries traverse state lines.
The original proposal would have determined materiality based on the potential impact of competitive retail demand on the systemwide LOLE and could change from year to year.
Under the revision, MISO would determine materiality based on the greater of the LOLE impact and a fixed percentage (0.5%) of the systemwide planning reserve margin requirement.
MISO said the change provides a “reasonable balance” between reliability and certainty.
Filing Delay Sought
Several stakeholders asked for a delay in the filing to better understand the latest changes.
“This congestion charge is just not clear yet,” Indianapolis Power and Light’s Ted Leffler said.
Minnesota Public Utilities Commission staffer Hwikwon Ham said he wasn’t yet comfortable with wording on the Tariff changes.
RASC Chair Gary Mathis said if the subcommittee demanded a filing delay, it would only be taken under advisement by MISO. The next scheduled meeting of the RASC will be held on Nov. 2, a day after MISO’s projected filing date.
Bladen said MISO is “very proud of how the proposal has evolved and the balance it strikes.”
“Thanks for your comments and contributions,” he said.
Tesla Motors and Panasonic have announced they plan to produce solar modules together if Tesla’s shareholders vote on Nov. 17 to approve a $2.2 billion acquisition of SolarCity.
The companies have signed a nonbinding letter of intent under which Panasonic would make solar cells and modules at the SolarCity factory in Buffalo, N.Y. Tesla would work out a long-term deal to buy and use those solar panels in a system combining them with its Powerwall and Powerpack battery storage products. That is all contingent, however, on Tesla’s acquisition of SolarCity.
Panasonic is presently spending $1.6 billion so it can produce battery cells that will be used for Tesla’s Model 3 electric car and energy storage products for home and utilities.
Luminant plans to shutter its Oak Hill, Texas, mine, which is one of the four lignite coal mines that feeds its Martin Lake power plant.
The company, which is Texas’ largest power generator, closed three small North Texas mines earlier this year to switch from lignite to Wyoming’s Powder River Basin coal.
Earlier this year, Luminant bought two major gas-fired power plants in northeastern Texas.
Jeffrey Keebler will be taking over as CEO and president of Madison Gas & Electric on March 1, 2017. He will succeed Gary Wolter, who is retiring.
Keebler, who has been with MGE since 1995, presently serves as senior vice president of energy supply and planning.
He holds a bachelor’s degree in finance and economics from the University of Wisconsin-La Crosse and a master’s degree in business administration from the University of Wisconsin-Whitewater.
Regulators: Empire Can’t Raise Oklahoma Rates without Hearing
State regulators last week rejected a request by Empire District Electric to raise Oklahoma customers’ rates to match those of Empire’s Missouri customers.
The state’s Corporation Commission did not rule out a rate hike, but it said Empire would have to go through a rate change hearing to establish justification.
Empire had asked for a rate increase of up to 45.37% per month per 1,000 kWh.
Layoff Plan Set for Fort Calhoun Ahead of Shutdown
The Omaha Public Power District released a plan last week to begin reducing the number of workers at its Fort Calhoun nuclear plant in Blair, Neb., which permanently ceased operations Monday.
As part of the decommissioning, the plant will lay off about 270 workers over the next 20 months in six batches. The first round of cuts — 60 people — is scheduled for Nov. 1, while the second round is set for the first quarter of 2017. Laid off employees will be placed in career transition workshops, OPPD said.
Enbridge announced last week a 5% workforce reduction across the company, amounting to the elimination of 530 jobs in the U.S. and Canada.
The company shed 370 positions in Canada and 160 in the U.S., 45 of which are in Houston.
Enbridge spokesman Michael Barnes said the cutbacks are not related to the company’s plans to purchase Houston-based Spectra Energy in a $28 billion deal expected to close early next year.
Minnesota Power Plans Shutdown Of Two Coal-Fired Generators
Minnesota Power announced last week that it will shut down two of its coal-fired generators in Cohasset by the end of 2018 as it transitions to natural gas and renewable resources.
In June, the Minnesota Public Utilities Commission ordered the utility to shut down Boswell Units 1 and 2 by 2022.
The utility has achieved a 25% renewable energy mix, beating the state’s goal of 25% by 2025. It expects to reduce carbon emissions on its system by about 20% by 2020 and 30% by 2025 compared with 2005 levels.
FERC last week approved an offer of settlement by MidAmerican Energy in which it agreed to reduce its reactive service rate from $0.18/MWh to $0.14/MWh, effective May 1, 2016. The settlement was uncontested.
WASHINGTON — Grid operators assured FERC last week they are confident in their ability to maintain reliability this winter, reporting improvements in gas-electric coordination and monitoring technology.
ISO-NE is making no promises beyond this winter, however, citing concerns over generation retirements and setbacks to efforts to improve New England’s stressed natural gas infrastructure.
It was the second panel on winter preparedness that the commission has convened since the polar vortex of 2014, when frozen coal piles, poorly winterized natural gas plants and other problems idled scores of generators in PJM and the Northeast.
The panel featured the same lineup as last year, except for PJM Vice President of Operations Mike Bryson, who took the place of former COO Mike Kormos, now with Exelon.
After the RTOs’ presentations, FERC staffers also professed confidence in a presentation of their Winter 2016-17 Energy Market Assessment.
The National Oceanic and Atmospheric Administration predicts normal winter temperatures for most of the U.S., with above-average temperatures in Alaska and the South, especially the Southwest, and below-average temperatures in North Dakota, Minnesota and northern Wisconsin. Gas storage is well above annual averages and the mild temperatures should mitigate gas constraints, staff said.
| NOAA
Despite the mild forecast and the unusually warm winter of 2015-16, the RTOs assured the commission that they were being proactive.
“We’re giving winter preparedness the same level of enthusiasm and hyper-awareness as we have the last year … so we’re certainly not sound asleep at the wheels at the heel of a mild winter,” said Wes Yeomans, NYISO vice president of operations. “We have a very good memory of very cold and tight conditions.”
Todd Ramey, vice president of system operations and market services for MISO, agreed. The RTO is “not taking our eye off the ball,” he said.
Unique Market Enhancements
Much of the speakers’ presentations covered ground familiar from last year, they admitted, but there have been a few new developments since then.
Both Yeomans and Bryson said their organizations had hired staff from the natural gas industry to support their control rooms in winter gas-electric coordination. Yeomans said the new hires “help us understand the gas commercial dynamics.”
Bryson said the person PJM hired “is very helpful to us, because he speaks gas, and we don’t.”
“It’s amazing because while we knew he was going to be a good hire, he has provided a lot of insight into the way the gas pipelines [and local distribution companies] think and it forces us to rethink our approach in some ways,” Bryson said.
Yeomans also said the Northeast gas pipeline system is displayed on a large video board in the NYISO control room, with pipelines under operational flow orders brightly lit, which he said enhances operators’ awareness. SPP’s Bruce Rew, vice president of operations, also highlighted his control room’s visualization technology, the Macomber Map, which depicts the transmission system geographically with power flows and constraints. (See ERCOT, SPP Collaborate to Improve Visualization Tool.) The map can also overlay weather systems with the grid, keeping operators aware of potentially hazardous conditions.
Ramey devoted much of his presentation to MISO’s new ramping product. The service holds back a portion of rampable capacity from five-minute dispatch to respond to short-term variations in load. (See MISO Seeks to Launch Ramp Product April 1.) “We found that to be a significant enhancement within our market design” and ensures “there is enough ramp on the system to meet future dispatch needs both known and unknown five to 10 minutes in the future,” he said.
| FERC
California
The closure of the Aliso Canyon storage facility following a massive gas leak continues to be a concern for California, but both CAISO Executive Director of System Operations Nancy Traweek and FERC staff told commissioners that the reduced gas capacity should not threaten electric reliability in the state.
Traweek said CAISO’s increased coordination with pipeline companies and advanced planning during the summer, when the state’s demand peaks, will mitigate any risks associated with Aliso Canyon.
CAISO has asked the commission to extend for an additional year temporary Tariff changes made in response to the loss of the storage facility. (See related story, FERC OKs Natural Gas Index for CAISO.)
“It’s exciting to see that now others in the West are benefiting from energy markets in real time and consolidated dispatch,” Traweek said.
ISO-NE
Peter Brandien, ISO-NE vice president of system operations, said New England would be fine this winter but he was not so sure about future winters.
“We have some units that have indicated they’re going to retire — we have those units this year,” Brandien said. “So this is probably going to be my last best winter.”
When the representatives were asked by Chairman Norman Bay about their overall comfort level going into the winter, all expressed optimism except Brandien, who did not directly answer the question. Instead he talked about the importance of Spectra Energy’s Algonquin Incremental Market pipeline and the region’s dependence on LNG imports.
Commissioner Cheryl LaFleur noticed this, asking how quickly the RTO can get an LNG delivery in the event of an emergency, such as the loss of a pipeline or nuclear plant.
Brandien said that although New England has had sufficient LNG supplies in prior winters, there is no guarantee that it will receive the same amount this year. The region is supplied by three primary facilities: the Everett Marine Terminal in Everett, Mass., Canaport in New Brunswick and the Northeast Gateway off the coast of Boston. LNG ships may dock at the facilities for days without offloading their cargo if they find a better price elsewhere, Brandien said.
LaFleur also asked whether the RTO was preparing for the coming generator retirements.
“I wish I had a good answer that gave me comfort, that as the non-gas resources retire that I had some sort of magic bullet,” Brandien replied. “The region doesn’t seem to be motivated to go down the path to expand the gas infrastructure. They want to invest in different things, [such as] solar, offshore wind, onshore wind [and] energy efficiency.”
‘Cautiously Optimistic’
“The outlook for winter is cautiously optimistic, with markets well supplied for the coming season,” FERC staff told the commission. “Staff will continue to monitor developments within the electric and natural gas markets, with particular attention paid to the issues at Aliso Canyon and in the Northeast.”
Bay praised the efforts of the RTOs. “I think this is another example of the benefits to consumers living in a region served by an RTO/ISO,” he said.
When asked whether presentations by the RTOs on winter preparations would continue every year, Bay said he found them “very informative and very helpful, and it’s so helpful to hear about the different things the RTOs/ISOs are doing to help prepare for winter …”
“Significant progress has been made [since the polar vortex], but there’s always more work to be done,” he said.
CAISO is seeking stakeholder input on how to respond to a solar eclipse that will significantly curtail output from California’s growing solar generation portfolio next August.
“It will not be a total eclipse [in California], but it will affect what solar production we have in California,” Jim Blatchford, an ISO senior advisor for short-term forecasting, said during a Oct. 20 call to discuss the issue.
The state will begin experiencing the effects of the Aug. 21, 2017, eclipse at about 9 a.m. PT, just as solar output is ramping up to its mid-day peak.
CAISO expects output to drop at an average rate of 46 MW/minute, from 6,603 MW to 2,828 MW at 10:22 a.m., when the eclipse reaches its totality.
During next summer’s eclipse, solar output in CAISO’s balancing area is expected to decline from 6,603 MW to 2,828 MW in fewer than 90 minutes, followed by an even sharper upward ramp as sunshine reemerges. | CAISO
“This is just for large-scale utility solar — not behind-the-meter,” Amber Motley, manager of short-term forecasting at the ISO, pointed out.
By that time, the sun will be completely obscured south of Portland, Ore., while California’s San Juaquin and Coachella valleys — both key solar producing regions — will see coverage of around 76% and 62%, respectively. Utility-scale solar output is forecast to be about 5,050 MW below what it would otherwise be without the eclipse.
The loss of output will require steady ramping from other generation sources to cover the 3,775-MW difference between the 9 a.m. peak and the 10:22 a.m. trough.
As the eclipse begins to pass, solar output is projected to increase at a rate of 56 MW/minute until noon — nearly four times the norm for that time of day. That will require a sharp downward ramp of other resources.
Motley noted that the ISO has not calculated the eclipse’s effect on California’s rooftop solar — currently estimated to be at about 5,000 MW — but expects that variable will be factored into the load rather than generation forecast.
CAISO must also focus on the impact of the eclipse on the Western Energy Imbalance Market. Arizona Public Service, NV Energy and PacifiCorp have a combined 3,270 MW in utility-scale solar and 816 MW in rooftop installations.
Arizona and Nevada will not be as affected as PacifiCorp’s sprawling territory, Blatchford noted. Utah alone will experience a 70% reduction in radiance.
The ISO is looking for advice from European electricity planners, who experienced a similar event last year. The planners increased reserves, made strategic use of pumped storage, limited planned outages and reduced DC line capacities between different regions. Germany procured twice its normal level of regulation reserves, while Italy curtailed PV production ahead of the eclipse.
“They were going to lose 90 GW, so they had a lot riding on this,” Blatchford said. “They did a very good job there, I thought.”
In light of Europe’s success, CAISO is hoping to develop a plan that encompasses the West at large. The effort would take up several possible mitigation measures, including cooperation with the Western Electricity Coordinating Council, gas-electric coordination, use of flexible ramping and hydroelectric resources, EIM transfer capability, reserve procurement and development of special operating procedures for the event.
“I think we have a lot of market products that we can use … and help with the coordination of this event,” Motley said.
Stakeholders are asked to provide feedback on potential measures by Nov. 3. The ISO expects to develop an eclipse mitigation procedure early next year, with publication of a final plan targeted for March.
“This is a unique event that we don’t get to deal with on a day-to-day basis,” Motley said.
A Wisconsin wildlife hospital and refuge lost its case against American Transmission Co., as a judge decided that the company has the right to remove trees from the sanctuary’s property.
Walworth County Judge Daniel Johnson ruled against Fellow Mortals Wildlife Hospital in Lake Geneva, Wis., following a four-day trial. Johnson ruled that ATC had the right to cut any trees in the 50-foot easement that in the company’s “reasonable opinion” could pose a threat to its 138-kV line in the future.
“So if the tree can grow tall enough that it reaches the lines even 50 years from now, it could come down,” said attorney Robert Kennedy, who represented the hospital.
Kennedy said this likely means the end for the sanctuary’s “Grandfather Spruce,” an estimated 100-year-old Norway spruce, that had only been periodically trimmed since the easement was granted. (See Wildlife Refuge Preps for Trial Against ATC Clear-Cut.)
But ATC spokeswoman Jackie Olson said the company has not yet formulated a tree-cutting plan for Fellow Mortals. “We respect the care and commitment that Fellow Mortals has for rehabilitating wildlife. Our team is working to plan our next steps,” she said.
No Precedent
At issue was a 1970 easement between the hospital’s previous property owner and ATC’s predecessor, Wisconsin Power and Light. Until recently, the transmission company had allowed periodic trimming of Grandfather Spruce and other trees.
The hospital filed suit after receiving notice that ATC planned to clear-cut the 50-foot easement, which Fellow Mortals said would remove screening that protects its animals from a nearby roadway.
Johnson said he regretted there would be an impact on the sanctuary, but he concluded that the issue was one of “cold, hard real estate,” Kennedy recounted.
Kennedy, however, said Johnson’s ruling would not set a precedent unless the case reached the appellate level.
“It’s possible that other courts at a trial level might rule differently,” he said, noting that many older aging easements bear language similar to the one currently held on Fellow Mortals. “It appears that ATC recognized back in the early 2000s that the easement language was ambiguous and they stopped using that wording. All of the newer easement language is refined,” Kennedy said.
“Easements like this literally allow power companies to destroy large swaths of natural forest,” Kennedy added. “When you consider how many thousand miles of line ATC has and the acreage it covers, that’s a vast amount of natural timber that’s going down. Legislators should have looked at that and done something to protect the natural growth.”
Hospital Prepares for Cutting
In response to the Oct. 13 ruling, Fellow Mortals founders Yvonne Wallace Blane and Steven Blane are working with their staff to move as many animals into the hospital as they can to shield them from the tree-cutting. “We have an order of priorities. I assume they’re able to start cutting at any time,” Yvonne Blane said.
Blane said Johnson visited the habitat and praised the hospital’s work.
“I think the judge didn’t have a choice,” Blane said. “What was worked out [in the 1970 easement] is ambiguous. No one is arguing that line areas [don’t] need to be safe and maintained. But after 46 years of trimming, it’s a change in policy that this company is making.”
Blane said the animal relocation includes capturing 39 birds that are permanent residents of the hospital’s sanctuary area, including a 36-year-old great horned owl that serves as a foster parent to other orphaned owls. She also said her staff is working to release any treated animals that are ready to re-enter the wild. But she said there’s not much she can do for four elderly deer that have been affected by chronic wasting disease and are permanent residents of the hospital; they will have to weather the cutting in a half-acre pen.
Blane said she was proud that the case did not provoke animosity. “ATC attorneys and staff were very respectful. Our issue is not with the people; it’s with the policy,” Blane said.
She said she does not rule out the possibility that the company might return to the occasional trimming schedules, leaving the trees standing. “Perhaps knowing that they can do whatever they want, someone with the ability to be harsh would be kind. They might not care about public opinion, but boy, that would make so many people happy.”
Hospital’s Work Continues
Blane said Fellow Mortals spent $40,000 in donations on the case and was not looking to appeal the decision. She said moving the hospital is impractical because it would cost millions. So the Blanes and their staff plan to continue their work from the current location.
“We have to adjust; we have to move on. We’re not going to let us make this bitter; we’re not going to stamp our feet here. We’re going to show some dignity. One defeat doesn’t ruin everything.”
On Oct. 12, after the third day of the trial, the hospital was called to rescue an immature red-tailed hawk that had gotten caught on an Alliant Energy power line. The bird, which was suffering from hypothermia and shock, had exposed leg muscle from struggling against the pole. Blane said the bird will be in the hospital’s care while the leg heals, perhaps over the winter.
The Sacramento Municipal Utility District (SMUD) announced on Friday it will begin negotiations with CAISO to join the Western Energy Imbalance Market, and other members of the Balancing Authority of Northern California (BANC) may follow.
BANC said a cost-benefit analysis with the Western Area Power Administration’s Sierra-Nevada Region (WAPA-SNR) determined that some of its six members would benefit from joining the EIM.
“We also view the EIM as a tool to help us integrate increasing penetrations of variable renewable energy resources in the future,” Jim Shetler, BANC’s general manager, said in a statement.

The joint powers agency said it will seek an arrangement allowing it to phase in members who want to join the EIM. Any agreement must recognize “the unique situation faced by the BANC members as public power entities and their existing arrangements,” the agency said.
SMUD would be the first BANC member to participate. The utility expects $2.8 million in yearly net benefits from transacting in the market — a figure that nets out the estimated $6.7 million in implementation fees and $2.6 million in annual operations costs.
In a presentation to its board of directors last week, SMUD management said EIM participation will improve the region’s renewable integration, potentially reduce reliance on gas-fired generation and provide “many of the benefits of regionalization while preserving [local] control over resources.”
“We view this is an extension of our existing market engagement with the CAISO,” said SMUD CEO Arlen Orchard. “SMUD also believes this further demonstrates our commitment to collaboratively work with California entities to help achieve the state’s energy and environmental goals.”
SMUD operates under an agreement that enables the utility to bid power into CAISO through a single hub in which one proxy price is selected to represent all connection points between the two areas. The ISO entered into a similar agreement with WAPA last year.
“We are extremely pleased to see a major regional public power utility like SMUD step forward to engage in the EIM,” CAISO CEO Steve Berberich said.
In addition to SMUD, BANC’s members are the Modesto Irrigation District, the cities of Redding, Roseville and Shasta Lake, and the Trinity Public Utility District.
The joint powers agency’s footprint extends from Modesto, Calif., to the Oregon border and includes a portion WAPA’s transmission grid and the U.S. Bureau of Reclamation’s hydroelectric resources in California. The agency’s members also control capacity on the California-Oregon Intertie, one of two high-voltage transmission lines linking California with the Pacific Northwest.

Founded 70 years ago, SMUD serves 1.4 million people, making it the sixth largest municipally owned utility in the country and the second largest in California, behind the Los Angeles Department of Water and Power.
BANC, which began operations in 2011, is the third largest balancing area in California and the 16th largest of the 38 balancing areas in the Western Electricity Coordination Council. Created as an alternative to CAISO, BANC is responsible for balancing load among its members, as well as coordinating system operations with neighboring balancing areas. BANC contracts with SMUD to perform day-to-day balancing functions.
BANC’s announcement came three days after Mexico’s grid operator said it will explore EIM participation for Baja California Norte, a region already interconnected with CAISO. (See Mexico Grid Operator to Explore Participation in EIM.)
The current EIM members are Arizona Public Service, NV Energy, PacifiCorp and Puget Sound Energy. (See Arizona Public Service, Puget Sound Energy Begin Trading in EIM.) Portland General Electric is slated to join the market in October 2017, followed by Idaho Power in April 2018.
CAISO’s latest draft of governing principles for a Western RTO is an improvement, but more changes are needed to win approval from regulators in the states in which PacifiCorp operates, speakers at a California Energy Commission (CEC) governance workshop said Monday.

“Our states are very sensitive to the perception that California can swing a veto,” PacifiCorp Transmission general counsel Sara Edmonds said.
Edmonds was referring to a provision that would institute load-weighted voting on the proposed Western States Committee (WSC) — the body comprising representatives from states considering participating in a future RTO. (See Latest Proposal Fills Out Western RTO Governance Plan.)
Veto Rights
As currently conceived, the voting rule — which requires any initiative be approved by 75% of voting members representing 75% of load — would not only prevent California from ramming through favored policies, but also permit that state to singlehandedly block any measures with which it disagrees.
“Ultimately, why we came to this [voting model] is that it gives some power to the weight of load, but gives all parties the ability to block a vote,” said Stacey Crowley, vice president of regional and federal affairs at CAISO. “It really does drive consensus.”
“I also understand that [weighted voting] is very important to California,” Edmonds said, noting that her company will seek to obtain feedback from state utility commissions on the issue.
Gardner | Western Resource Advocates
“I can tell you that a weighted voting model that gives California veto power will be problematic,” said Jennifer Gardner, an attorney for Western Resource Advocates (WRA), a Colorado-based environmental group that supports the ISO’s bid to regionalize the Western grid. (See Q&A: Western Resource Advocates Sees Benefits from Western RTO.)
In an alternative voting proposal submitted to the CEC last month, WRA pointed out that California would represent 76% of the load in an expanded ISO in which PacifiCorp was the only service area outside the current footprint. Including Arizona Public Service and NV Energy would still leave California with a 61% share, which would fall to a slim majority of 52% with the addition of Portland General Electric, Puget Sound Energy and Idaho Power.
Tiered Voting
WRA’s proposal: a tiered voting process in which every state would hold one vote under most circumstances and the WSC would attempt to work toward consensus. For issues where consensus voting might be difficult, other rules would apply, such as majority voting for day-to-day decisions and two-thirds majority voting for amending bylaws.
Load-weighted voting could apply for decisions related to the WSC’s areas of “primary authority” — tariff revisions that currently fall under the remit of state regulators. The weighting would be simplified so that any state with more than a 50% of the RTO’s load would wield two votes, while all others would get one. Gardner noted that the New England States Committee on Electricity follows a similar practice.
“What’s really important with that group is that they achieve all of their decisions based on consensus,” Gardner said. “If not, they revert to voting based on load.”
Florio | Linkedin
The California Public Utilities Commission’s Mike Florio said he was “taken aback” by the WSC’s limited role in the initial development of the resource adequacy and transmission access charge rules for an RTO.
“I think the counting rules [for resource adequacy] should be uniform for all the states,” Florio said. “That’s why it’s something that should fall to the Western States Committee.”
The ISO has played its strongest role with local resource adequacy, but the process is still in play for flexible capacity, Florio said.
“There is a significant role for the states there that hasn’t been outlined to date,” he added. “I’d think the states would want to have some kind of backstop role.”
Clarity on Roles
“I think we need to get much more clear on the very specific roles between the ISO board and the WSC — and versus the WSC,” said Dede Hapner, vice president of FERC and ISO relations with Pacific Gas and Electric.
Hapner | University of Michigan
Hapner said the most recent governance proposal provided a larger role for the WSC than the previous version and that industry participants must think about areas where the committee could trump the board.
“How much will be acceptable to the FERC?” she asked.
Hapner also advocated for the creation of a “transitional” WSC to begin quickly addressing issues of concern to participating states.
Concurring with that view was Rachel Gold of the Large-Scale Solar Association.
“Seating the WSC earlier — even in informal fashion — will be important to getting to ‘yes’ here,” she said.
Gendron | BPA
Other Western states would likely want to weigh in on rules around resource adequacy and greenhouse gas accounting, Gold noted.
Mark Gendron, vice president of power services at the Bonneville Power Administration, had a similar take. While his agency was pleased with the proposal’s attention to complex technical issues such as resource adequacy, it thinks it will take time to work through those matters.
“We’re concerned that some of the decisions on some of these technical issues could be made prior to the [seating of the] new board and Western States Committee,” Gendron said.
Potential Shortcoming
Cromwell | Linkedin
Robert Cromwell, director of power contracts and resource acquisition at Seattle City Light, pointed out a potential shortcoming in the ISO’s decision to make the WSC a body of general state representatives rather than regulators: Utility commissions might still have to weigh in on whether they could fulfill a WSC decision based on their own state laws.
The panelists found some positives in the latest proposal as well.
“We have repeatedly requested that consumer and environmental advocates be separated [in the Transitional Committee guiding development of the RTO],” Gardner said. “We appreciate CAISO taking our concerns.”
PacifiCorp’s Edmonds supported the proposal’s creation of a Nominating Committee and Approval Committee to select members of the final RTO board — the latter of which would comprise WSC members.
“The current revised proposal appears to shift more responsibilities to states, and I know our states are looking at this,” Edmonds said.
Edmonds also noted that the fleshed-out proposal deferred fewer governance design details to the Transitional Committee, calling that a “good thing.”
Florio and Gendron both complimented the proposal for emphasizing that the WSC should be a collaborative body.
Weisenmiller | CPUC
“I think the emphasis on a collaborative, consensus-based process is appropriate,” Florio said.
Hapner supported the proposal’s shorter transition to seating a final board and agreed with the redistribution of sector representation on the Transitional Committee, which folded generators and marketers into the independent power producers sector and created an exclusive grouping for end-use consumer advocates.
“The consensus seems to be that we’re making progress, but there’s still a lot of work to be done,” concluded CEC Chair Robert Weisenmiller.
