MISO’s Independent Market Monitor is angling for demand response offer floors and attestations of expected levels of energy consumption in the wake of an Arkansas steel mill’s gaming of the MISO demand response market.
Meanwhile, a second demand response resource in MISO might be under fire for promising load reductions and not delivering them.
In late August, FERC accepted a $35 million total settlement between Big River Steel in Osceola, Ark., Entergy Arkansas and FERC’s Office of Enforcement, of which $21 million will be returned to MISO customers. The steel mill for years collected payments from MISO for demand response while not actually reducing electricity use. (See FERC OKs $21M Settlement in Arkansas Steel Mill’s DR Scheme in MISO.)
Carrie Milton, of the Independent Market Monitor’s team, said the IMM is advising MISO to reinforce its rules for demand response resources (DRRs) “to prevent similar gaming in the future.”
“After seeing this kind of conduct, we have recommended [that] MISO establish an offer floor for DRRs and that DRRs indicate their forecasted, pre-curtailment expected consumption,” Milton said during an Oct. 5 Market Subcommittee meeting.
Milton said IMM staff recently referred another MISO DRR to the Office of Enforcement for offering “phantom load reductions” similar to Big River Steel. In this case, the unnamed company collected more than $35 million in payments from MISO.
Neither MISO nor the IMM revealed the name of the company involved with the possible new investigation. MISO said the IMM’s screening first uncovered the “information that led to FERC’s investigation” of Big River Steel.
Milton said the IMM team is working with MISO to gain support for the DRR rule changes.
MISO did not say whether it agrees with the IMM’s proposal but said it is open to exploring with stakeholders what improvements might be necessary.
“Following any situation like this, MISO is closely collaborating with the IMM and FERC to evaluate potential enhancements to help prevent similar conduct in the future, which will be vetted through MISO stakeholder process in an open and timely fashion,” spokesperson Brandon Morris said in an emailed statement to RTO Insider.
LANSING, Mich. — Michigan’s Public Service Commission would oversee siting of major renewable energy projects under a package of legislation introduced in the state’s House of Representatives, which immediately drew praise from supporters and outrage from opponents.
HB 5120 and companion bill HB 5121 would preempt local zoning and give the PSC authority for siting of wind, solar and energy storage facilities of 100 MW or more. HB 5122 and HB 5123 are identical except that they would apply to solar energy storage facilities between 50 and 100 MW. No hearing has been set on the legislation at this time.
An official with the Michigan Townships Association (MTA) immediately blasted the legislation as an “authoritarian” attempt to force small, rural areas to accept large energy facilities and bar local voter referendums on the projects.
“Yes, renewable energy facilities can be contentious in some communities. But the answer is not — and is never — to silence the voices of the impacted residents and communities,” said Neil Sheridan, executive director of the association.
Also opposing the package is the Michigan Farm Bureau, which has said the legislation could harm Michigan’s agriculture industry, as well as the Michigan Association of Planning and the Southeast Michigan Council of Governments (SEMCOG). SEMCOG represents all the city and county governments in Michigan’s largest population area, including Detroit and Wayne, Oakland and Macomb Counties (though those entities also have their own lobbyists).
Not taking a position on the bills thus far are two other significant local government interest groups: the Michigan Association of Counties and the Michigan Municipal League. The Municipal League represents the state’s cities and villages, including Grand Rapids and Ann Arbor (the second- and fifth-largest cities in Michigan, respectively), two communities that have been more aggressive in dealing with climate change issues.
The Municipal League also recently supported HB 5028, which would prohibit homeowners’ associations from barring solar panels on houses.
The MTA represents the more than 1,200 townships in the state — ranging from Canton Township in Wayne County, with a population of greater than 90,000, to Pointe Aux Barques Township in Huron County, population 15 — where most of the major disputes about building renewable energy projects have taken place.
Backing the bills is a coalition of industrial groups that work on and for renewable energy, including the Michigan Energy Innovation Business Council and the American Clean Power Association. Erika Kowall, director of Midwestern Affairs for the ACP, said the legislation showed Michigan was “taking a meaningful step to help counter project delays and ensuring that a clean energy future will unlock economic investment and jobs across the state while protecting the environment.”
Peder Mewis with the Clean Grid Alliance said Minnesota and Wisconsin have systems similar to what Michigan is proposing that maintain local oversight on smaller projects while having state oversight on larger projects.
In keeping with its winter estimates from previous years, MISO said it could run into trouble in January should it experience high load or high outages.
In a winter outlook published last week, MISO said it should fare well over the season under typical demand and generation outages. However, the RTO said it may need to declare an emergency in January if a deep freeze spurs either unusual generation outages or elevated demand.
Otherwise, MISO said it should have sufficient firm resources to cover winter peak load forecasts.
The grid operator predicts a 96.4-GW peak in December under typical circumstances or 101.5 GW in a high-load scenario. It said it should have nearly 115 GW of firm resources to cover peak, though that could be downgraded to 110.7 if generation outages creep up.
MISO said its system most likely will realize a nearly 102-GW peak in January under typical demand or up to 107 GW in an amplified demand situation. It said it should have as much as 121.8 GW or as little as 100.7 GW of firm resources available in its fleet, all but guaranteeing the need for emergency procedures and resources.
System strain will ease in February, MISO said, with a 97.6-GW peak or a less likely 102.4-GW peak. In either case, the RTO said it should be able to handle demand without an emergency, having anywhere from 121.6 GW to 111 GW available in firm resources.
MISO anticipates it will have access to about 10 GW worth of load-modifying resources and other operating reserves this winter if it orders emergency procedures.
MISO declared one maximum generation event last winter during a Dec. 23 arctic blast, a product of high load and high generation outages. (See MISO Winter Recap Centers on December Emergency.)
FERC on Friday rejected a rehearing request by a solar developer of the commission’s denial of its complaint and a tariff waiver over SPP’s interconnection studies for the planned facility (EL22-89).
The commission, citing Allegheny Defense Project v. FERC, denied the rehearing request by “operation of law.” FERC modified the discussion in its previous order but arrived at the same conclusion.
The D.C. Circuit Court of Appeals’ 2020 ruling in Allegheny found the commission no longer could grant rehearing requests “for the limited purpose of further consideration.”
The developer behind Cage Ranch Solar and Cage Ranch Solar II, a 900-MW project in West Texas, sought to reverse the commission’s May decision that found Cage Ranch had not met its burden to show that SPP violated its tariff or conducted its studies in an unjust and unreasonable manner. FERC said the solar facility did not demonstrate the study models underlying the cluster study were defective. (See FERC Sides with SPP Over Interconnection Study Complaint.)
Cage Ranch argued FERC erred by finding its interconnection was the “but for” cause of network upgrades, failing to address the developer’s cost-causation arguments; and that its waiver request did not address a concrete problem.
The commission said it was unpersuaded by the rehearing arguments and continued to find that Cage Ranch had not met its burden under the Federal Power Act to show SPP violated its tariff or that its allocation of costs was otherwise unjust and unreasonable.
“Nothing in the rehearing request demonstrates that the [SPP] study models underlying [SPP’s study] are defective,” FERC said. “Accordingly, we continue to find that Cage Ranch has failed to demonstrate that the network upgrades assigned to Cage Ranch … and the associated [study] payment amount that Cage Ranch was required to post, are unjust and unreasonable and unduly discriminatory or preferential. … None of the issues raised in the rehearing request persuade us that the commission’s conclusions were in error.”
Cage Ranch had said the SPP study in question should not have been used to determine interconnection costs for the solar farm and other customers in the study group because SPP failed to resolve alleged nonconvergence issues. FERC pointed out that the grid operator assigned Cage Ranch network upgrade costs using a modeling approach it applies to all interconnection customers.
Cage Ranch Solar also filed a challenge of FERC’s earlier ruling in August with the D.C. Circuit. It said the orders violate the Federal Power Act and the Administrative Procedure Act and are arbitrary, capricious and an abuse of discretion (23-01227).
Independent entities cannot review and challenge tank congestion charges and revenue credits in the annual true-up process for the cost-of-service agreement between ISO-NE and the Mystic Generating Station, FERC ruled Friday (ER18-1639).
The commission also ruled against a request by a group of municipally owned utilities for additional audit disclosures related to the agreement, saying that ISO-NE’s existing audit procedures and disclosures are adequate.
The ruling responded to both the municipal utilities’ request for additional information and a request for rehearing by Constellation Mystic Power, which argued against FERC’s determination that “interested parties” can review and challenge the true-up. That “could be read to allow interested parties to obtain information that is commercially sensitive, and that poses a security risk,” the company said.
In contrast, the utilities argued that the significant costs of the agreement — which they estimated to be more than $400 million over the first 10 months — necessitated the disclosure of additional information to allow interested parties to challenge the credits and charges. (See Public Power Groups Seek Information on Mystic Agreement.)
Credits account for revenues that Mystic earns from sources other than the agreement, while tank congestion charges refer to any costs associated with the increased need for uneconomic self-scheduling or short-term vaporization LNG.
FERC sided with Constellation, reversing its previous determination and also agreeing that shared revenue from third-party natural gas vapor sales should not be included in the true-up process. The commission said these contested issues are inconsistent with the Mystic agreement’s true up process because “none of them are projected in advance, but rather they are each settled and audited on a monthly basis.”
The commission also denied the municipal utilities’ request for additional audit information, which is “not supported by the Mystic agreement and unnecessary, given the attention that ISO-NE, its auditors and the Market Monitor give these items on a regular basis.” The request “goes beyond the terms of the Mystic agreement, which vests ISO-NE with audit rights and requires ISO-NE to maintain the confidentiality of audit-related information.”
“Allowing all interested parties to review Mystic’s revenues and revenue credit could require disclosure of proprietary information about Mystic’s actual fuel costs,” FERC wrote. “We recognize the potential competitive harm to Mystic, Constellation LNG and the market that could ensue from the disclosure of unmasked, offer-specific, commercially sensitive information to third parties.”
FERC wrote that it is “sympathetic” to the concerns about the high costs of the Mystic agreement, but “there is no record evidence that the Mystic agreement formula rate is being improperly executed.”
“The existing cost review and audit processes, which are facilitated by ISO-NE, its auditors and the Internal Market Monitor … are sufficient to ensure that Mystic adheres to its filed rate,” FERC added.
FERC also accepted a proposal ISO-NE had filed as an intermediate solution, which stopped short of the broad disclosures requested by the public power groups but allows for releasing redacted audit reports, providing summaries of its discussions with Constellation about fuel supply decisions, and making a member of Levitan & Associates’ tank congestion audit team available for questions at several points throughout the agreement.
“We are pleased that the commission has recognized the significant information the ISO has made available regarding the ongoing auditing of Constellation’s fuel supply decision,” an ISO-NE spokesperson told RTO Insider via email. “We will continue to work with Constellation and our stakeholders on ways to provide additional information while protecting confidentiality.”
Hit by one storm after another, Vermont’s largest electric utility is proposing to install battery systems in certain customers’ homes as a resilience measure.
The plan is one piece of Green Mountain Power’s 2030 Zero Outages Initiative, which it calls a first-in-the-nation combination of hardening power lines, creating community microgrids and placing distributed storage assets strategically across its service area — then crunching external data to find the best strategy against power outages on each of 300 circuits.
GMP has been promoting in-home storage units for eight years, and its residential customers now have 5,000 battery units in their homes. The customer waitlist stood at 1,200 when the Vermont Public Utility Commission in August lifted the enrollment cap on two GMP programs to promote in-home storage.
Under one program, GMP leases Tesla Powerwall batteries to customers for 10 years at a discount; under the other, GMP provides an up to $10,500 incentive to ratepayers who buy a system on their own.
In a petition to the PUC Monday, GMP proposes to spend $280 million to increase storm resilience (Case No. 23-3501-PET). Some $250 million would be used to harden 8 to 10% of GMP’s 10,000 miles of overhead lines — either by moving them underground or by protecting them with spacer cables or other devices.
The other $30 million would place battery units in some homes in what GMP calls Zone 4 — areas served by single-phase “last-mile” power lines in rural areas. Some parts of the mountainous state have sufficiently few customers per mile that moving power lines underground or even just hardening them would be less economical than installing batteries.
The utility would cover the cost of the batteries so individual homeowners who couldn’t afford the upfront cost of a battery wouldn’t be left behind.
Ratepayers would pick up the tab, although GMP plans to pursue federal funding.
Other pieces of the puzzle include trailer-mounted energy storage, demand-response-enabled EV chargers and electric school buses with V2G capability.
GMP said the unique aspect of the 2030 Zero Outages Initiative is that it takes all these pieces and overlays them with federal community vulnerability data, topography and other metrics to calculate the best resiliency strategy for each circuit.
Utilities and grid operators nationwide are wrestling with the long-term implications of the clean energy transition and the immediate impact of extreme weather blamed on climate change.
In Vermont, the storms have been coming fast and furious. GMP has spent $115 million on repairs from major storms in the past decade, $45 million of it in just the past year. The three storms with the highest number of outages in GMP history have all hit in the past 12 months.
That is unsustainable, GMP said. It needs to accelerate resiliency efforts so future storms cause less damage and fewer outages.
GMP President Mari McClure said in a news release Tuesday: “We all see the severe impacts from storms, we know the impact outages have on your lives, and the status quo is no longer enough. We are motivated to do all we can to combat climate change and create a Vermont that is sustainable and affordable, but we must move faster. Together with our customers, regulators, our communities and that Vermont spirit that manages to innovate despite all odds, we have all we need to revolutionize the energy system and ensure a stronger, more affordable Vermont.”
If the PUC approves, the $280 million would be spent over the next two years. GMP said it expects the improvements to start yielding savings on storm recovery costs by 2026 and will submit a request for an expanded second phase of improvements to be made through 2030.
In a promising sign, the first 50 miles of power lines relocated underground came through the recent series of major storms undamaged and trees that fell on new spacer cables caused no outages.
GMP serves more than 270,000 homes and businesses in Vermont. It is by far the largest electric utility in the state, and the only one owned by investors.
A spokesperson told NetZero Insider Tuesday that GMP is confident it can secure enough storage units, even amid surging demand for batteries. It already has been working with suppliers.
Thermal energy storage (TES) powered by renewables could be a flexible, cost-effective way to decarbonize heavy industry in the United States, if such projects could access wholesale power prices and rate structures based on cost causation, says a new report from the Renewable Thermal Collaborative and Center for Climate and Energy Solutions.
The technology essentially is a two-fer, capable of providing the high-temperature heat needed for a range of so-called “hard-to-abate” industrial processes, as well as vital grid-support services to ensure power system reliability, according to the report, authored by industry consultants The Brattle Group. Like other storage technologies, it also can be used as a hedge against volatile fossil fuel prices, acting as a sponge to absorb excess renewable power during times of high production and low costs, and discharging during periods of peak demand.
“If widely deployed to their maximum potential, renewable-powered thermal batteries could displace the entirety of the emissions associated with industrial heating demand, amounting to 779 million metric tonnes (MMT, also equivalent to 1 Megatonne) of carbon dioxide equivalent (CO2e) emissions per year in the United States, or approximately 12% of total economy-wide GHG emissions.” the report says.
Globally, renewable TES could slash industrial CO2 emissions by 6,000 MMT per year, or 14.5% of all energy-related emissions, the report says.
A first step for scaling the technology is simply getting it on the radars of critical stakeholders, from potential industrial users to utilities and state and federal regulators, the report says. For example, policymakers and regulators should classify renewable TES as a “qualified technology solution that can be considered equally alongside other alternatives in” state and federal studies examining economy‐wide and grid decarbonization pathways, the report says.
Similarly, the report calls on grid operators to recognize the attributes of renewable TES as a technology that can ramp within minutes or even seconds and operate as either a dispatchable or flexible resource.
Speaking during a recent webinar on the report, Phillip Stephenson, vice president of business development for startup Electrified Thermal Solutions, praised the study for “finally laying out what I think is a great secret we want people to know. … We actually just need to change the rules a bit to match costs and benefits to make this work.
“We are not asking for dumping subsidies on us to unleash a lot of decarbonization and [show] how real these benefits are and how widespread the benefits can be in terms of the grid, which means really [for] the energy transition and society,” he said.
‘The Right Thing to Do’
Thermal energy storage is based on the same basic technology as a toaster or electric stove. Electric power is run through a “resistive material” ― for example, some form of carbon or graphite that impedes power flow, creating heat that can be stored.
The technology has long been used in space and water heating applications, especially in district heating or combined heat and power systems, to capture waste heat for heating and cooling. Such systems often store heat in vats or other large containers of water.
But the high temperatures needed for heavy industry — such as glass, paper and chemical production — typically have required the combustion of fossil fuels. Many companies in these sectors anticipate decarbonizing their factories either by switching from fossil fuels to green hydrogen or cutting their fossil fuel emissions with carbon capture and storage. (See Summit Showcases New Technologies to Accelerate Industrial Decarb.)
Instead, startup companies like Electrified Thermal and Antora Energy have developed technologies that can turn renewable power into high-temperature heat that is stored in special bricks or carbon blocks and released as needed. At present, these and other renewable thermal storage companies can provide heat of up to 750 degrees Celsius, or 1,382 degrees Fahrenheit, high enough to cover 75% of all industrial heat demand, the report says.
Antora, a startup with funding from Bill Gates’ Breakthrough Energy Ventures, recently announced a pilot project in California where the company’s system produced heat at 1,800 degrees Celsius, or more than 3,200 degrees Fahrenheit, high enough to cover almost any industrial process.
Greg Wellman, technology manager of decarbonization for Eastman Chemical Company, talked about the commercial benefits of renewable TES for his firm, a Fortune 500 company producing a range of “specialty materials,” such as bird-friendly glass for building facades.
Spun out of Eastman Kodak in the 1990s, the company is looking at thermal storage because it fits well with its existing natural gas-based infrastructure, and the new systems are modular, meaning they can be sized to try out on a single process or to produce industrial heat for a whole factory, he said.
Another reason Eastman is looking closely at the technology is its potential for price parity with natural gas in the near future, Wellman said. “[When] you think about what’s the long-term trajectory of natural gas pricing, what’s the long-term trajectory of electron pricing … there’s going to be a compelling case to make these changes [to renewable TES], not just because it’s the right thing to do but also because it’s a financially right thing to do,” he said.
The Brattle report notes that for companies like Eastman, renewable TES could allow fuel switching, that is, keeping fossil fuel infrastructure, and natural gas, as backup generation to respond to price fluctuations or emergency events.
Stephenson said the technology also could be an attractive option for utilities anticipating new, higher peaks in energy demand as industrial customers seek to electrify their plants and processes. With renewable TES, industries could electrify “without having those peak demand impacts,” he said.
For utilities, the benefits include improved “economics on their entire system by being able to take all that new heat load coming from the customers … but tuck it under their existing peak by using only off-peak energy,” he said.
Depending on project configuration and rate structure, renewable thermal energy storage can be cost-competitive with natural gas. | RTC
Good for All Customers
Beyond raising industry awareness of renewable TES, scaling the technology will depend on getting it to price parity with natural gas, which, in turn, may depend on a range of factors, such as the configuration of individual systems, rate structures and access to wholesale power prices.
Price parity could vary across system configurations, the report shows, specifically whether the renewable power is located off- or on-grid, whether the system can export power to provide grid-support services or whether the renewable power is coming from the grid itself.
At present, the report says, the most cost-competitive configurations for renewable TES are for projects that “self‐supply or directly contract with a renewable power supplier in an off‐grid or partially grid‐connected status.”
But project configuration often is determined by the specifics of a customer’s site, said Nick Soncrant, Antora’s head of business development.
“If a customer is space-constrained, colocated, new-build renewables will be pretty tough to implement,” Soncrant said. “If a customer is in a renewable-dense region … where the price of power is competitive with natural gas, we can look to work with utilities either under their existing tariff or partner with them to develop a new wholesale market tariff.”
Such new “modern” rate structures are vital for renewable TES to successfully compete with natural gas, the report says. Traditional rate structures, which include generation, transmission and distribution fees, presume “the customer can’t change when they use power,” said Kathleen Spees, a Brattle Group principal and lead author of the report.
For renewable TES to pencil out, Spees said, will require “very principled ratemaking structures of cost causation. … You only apply costs that are really relevant and caused by this sort of customer, which are low because you can really optimize when you would withdraw any power from the grid with a thermal battery,” she said.
“The good news about these modern rate structures, of course, is that they are good for all customers,” Spees said. “They’re good to incentivize all customers to behave in ways that actually reduce costs to the power grid. There is just much more potential and capability to shape whether and when any consumptions patterns take place.”
The report points to two electric cooperatives, the Vermont Electric Cooperative and the Victory Electric Cooperative in Kansas, that have adopted new rate structures based on cost causation. The Victory co-op, for example, has a rate for industrial customers that, the report says, is “aligned with wholesale power prices, consumption during system coincident peak demand and other (smaller) cost components, including local delivery charges.”
841 and 2222
Whether renewable TES projects will be able to access wholesale prices raises another key question: Is the technology covered under either FERCOrder 841 or Order 2222, regulations that require, respectively, that energy storage and distributed energy resources be able to participate in wholesale power markets.
To date, Spees said, “that question has not been specifically asked or answered” and would require one or more affirmative rulings from FERC.
The fact that renewable TES can provide multiple value streams, both storing and discharging power, adds another layer of complexity to the issue, said Jordan Kearns, vice president of project development for Antora Energy.
“We … and other folks in the space have systems that can produce electricity back from these thermal batteries, and it’s kind of hard to argue that’s not a battery that would be covered under 841 or 2222,” Kearns said in an interview with NetZero Insider. “But then how do you treat the heat [that] goes off of it? Are you going to be punished for capturing and … putting that waste heat to good use?”
The report offers several recommendations for grid operators and FERC to ensure renewable TES can participate on a level basis in energy, capacity and ancillary markets, including:
Having the same size requirements for standalone batteries and renewable TES, with a minimum of 100 MW.
Establishing “distinct participation models” for different renewable TES configurations, such as standalone thermal batteries with controllable demand, colocated renewable electricity and thermal battery systems that can be scheduled to charge or discharge power, and TES systems that receive renewable power from the grid.
Allowing thermal batteries to access wholesale energy prices based on the same locational marginal price available to generation resources and electric batteries.
NYISOannounced on Tuesday that the state broke its hourly wind generation record Sunday, generating 1,939 MW from 28 wind power facilities.
The ISO said that meant wind energy met 12.9% of New York state’s electricity demand between 3 and 4 p.m. that day. The previous record of 1,897 MW was set Feb. 17, 2022, during the 1 a.m. hour.
“Wind generation is an important part of the diverse energy mix that helps maintain system reliability for consumers across the state,” NYISO CEO Rich Dewey said in a statement. “While there’s much more work to be done to decarbonize our system, this new record demonstrates wind energy’s increasing contribution to the state’s climate goals.”
“New York’s clean energy transition is ensuring more homes and businesses across the state are powered by renewable energy sources like land-based wind — a shift that is especially important during times of peak demand,” said Doreen Harris, CEO of the New York State Energy Research and Development Authority.
The milestone comes as offshore wind developers exit the power purchase agreements off New England and seek to renegotiate them amid high inflation and supply chain constraints. (See Park City Wind to Cancel PPAs, Exit OSW Pipeline.)
None of New York’s four OSW projects under development have made that move yet, but their developers have said they may be forced to do so if the Public Service Commission does not grant NYSERDA’s request to adjust the reference price for offshore wind renewable certificate contracts to account for inflation. The PSC is set to rule on the matter Thursday (15-E-0302/18-E-0071).
“Unforeseeable economic forces — including unprecedented global supply chain bottlenecks, high inflation [and] rising interest rates, along with permitting and grid delays — have eroded the financial viability of” Empire Wind and Beacon Wind, their developers told the PSC in comments filed Friday, “to the point where contract restructuring is required to permit those capital-intensive projects to move forward. Notwithstanding these severe market shocks, however, the projects remain the most cost-effective means of fulfilling the [state’s] renewable energy mandates.”
In the same docket Friday, the PSC granted a one-year extension for NYSERDA to create an implementation plan for Tier 4 of its renewable resource procurement program. (See NYSERDA Can’t Meet Deadline to Design New REC Plan.)
SACRAMENTO — Nine of the world’s largest manufacturers and suppliers of building heating and cooling equipment have signed an agreement to support California’s goal of having 6 million electric heat pumps installed by 2030.
The deal was announced at a two-day Summit on Building Electrification co-hosted by the California Energy Commission and the Electric Power Research Institute (EPRI), held at the California Natural Resources headquarters in Sacramento.
The broad public-private partnership is being convened in a move CEC member Andrew McAllister said will be “critical in aligning policy and reality.”
The goals of the program, McAllister said, are to:
create the manufacturing capacity to help achieve the state’s goal of installing 6 million heat pumps by 2030;
ensure heat pumps are good citizens of the electric grid by enhancing efficiency and incorporating load flexibility;
collaborate with the CEC to develop a public-private partnership to facilitate policy and market support to bring heat pumps into the mainstream.
“The pledge builds on policies and programs already underway at the Energy Commission, the [California] Air Resources Board, the [California] Public Utilities Commission and the Governor’s Office of Business and Economic Development, GO-Biz. The activities are supported by the California Climate Commitment and federal Inflation Reduction Act, which combined will provide $1.3 billion for efforts to reduce emissions from buildings,” McAllister said.
A body will be convened that includes the nine manufacturers plus other companies in the supply chain, public interest groups, utilities, labor groups and state agencies. McAllister said the partners in the group could “collaborate on initiatives focused on, but not limited to, consumer awareness, contractor training, product availability, performance, efficiency, load flexibility, refrigerant management, data, equity and financing.”
“We can’t do it alone. It takes strengths of partnerships like this to achieve the kind of massive market transformation required to reach our goals,” he said.
The manufacturers are AO Smith, Carrier, Daikin, Johnson Controls, Lennox, LG Electronics, Mitsubishi Electric Trane HVAC US, Rheem Manufacturing and Trane Technologies.
Driving consumer acceptance is a key part of the program, he said. “This new commitment will ensure that grid-friendly heat pumps are widely available and can help consumers understand why they’re a better choice for both comfort and for the climate. The partnership will promote a comprehensive consumer awareness campaign to educate consumers on the benefits of electrification and work on ways to ease the purchasing process.”
The group will periodically report on progress toward meeting the goal of having 6 million heat pumps installed in buildings across California by 2030.
FERC responded to ISO-NE’s request for rehearing on its Order 2222 compliance Friday, agreeing to delay the required timing of implementation while providing a clarification about the responsibility and role of distributed energy resource (DER) aggregators and utilities in providing ISO-NE with metering information and data (ER22-983-002).
Order 2222 directed RTOs and ISOs to remove barriers for aggregations of DERs to participate in wholesale markets. ISO-NE filed its initial compliance in February 2022, and FERC partly accepted and rejected it in March 2023. (See FERC Gives ISO-NE Homework on Order 2222.) ISO-NE requested a rehearing at the end of March.
A significant portion of FERC’s order Friday focused on its requirement that DER aggregators be responsible for reporting the necessary metering information to their respective RTO or ISO. In ISO-NE’s compliance filing, the organization proposed to task the host utility — which refers to either a transmission owner or a distribution utility — with this responsibility.
“Shifting the meter reporting role for [DER aggregations] to the DER aggregator would treat DERAs differently from all other resources participating in New England Markets and place them at a disadvantage relative to all other resources,” ISO-NE wrote in its March request for rehearing.
ISO-NE also interpreted FERC’s order in March to require the exclusion of host utilities from the flow of metering information from the DER aggregator to the RTO. ISO-NE argued that because host utilities typically are in charge of metering, giving the responsibility to the DER aggregator while excluding the utility from the process would be difficult to implement and would require new infrastructure and tariff changes.
In its response to the rehearing request, FERC maintained that the DER aggregator is responsible for providing metering information to ISO NE.
The commission said it disagreed with the “underlying interpretation upon which ISO-NE bases its rehearing request” and said Order 2222 “does not preclude metering data coming from or flowing through the host utility.”
“Metering data may come from or flow through distribution utilities if ISO-NE coordinates with distribution utilities and relevant electric retail regulatory authorities to establish protocols for sharing such metering data and explains how such protocols minimize costs and other burdens and address concerns raised with respect to privacy and cybersecurity,” the commission wrote.
FERC said this clarification would preclude the need for the significant metering changes and burdens highlighted by ISO-NE in its rehearing request.
Also in Friday’s order, FERC sustained part of the March order directing ISO-NE to explain or alter its measurement requirements for some classes of behind-the-meter DERs.
Time Change
In ISO-NE’s initial compliance filing in 2022, the RTO wrote that it would need a response from FERC no later than Nov. 1, 2022, to include distributed energy capacity resources (DECRs) in Forward Capacity Auction (FCA) 18, which is scheduled for 2024 affecting the 2027/28 capacity commitment period. Since FERC did not make a determination until March 2023, ISO-NE argued in its rehearing request that it should not be required to include DECRs in FCA 18.
FERC accepted this request Friday, noting ISO-NE has proposed a new effective date that would require DECRs to be included in FCA 19.
Commissioner Christie’s Dissent
Commissioner Mark Christie dissented with Friday’s order, as he did with the commission’s order in March regarding ISO-NE’s compliance filing.
“Today’s order represents yet another example demonstrating that Order No. 2222 has created nothing short of an incomprehensible quagmire bearing a substantial price tag that will inevitably add to the rising power costs already faced by consumers,” Christie wrote.
He expressed his concern that the order does not adequately address ISO-NE’s concerns and will require “yet another return to the drawing board for ISO-NE and its market participants.”
Christie added that the order “uses the ‘clarification’ as a sword to dispense with the rehearing request, but also as a shield from providing substantive explanation on how this ‘clarification’ addresses each of ISO-NE’s problems and concerns.”
