The nation’s largest public housing authority is trying to jumpstart development of lower-voltage cooking equipment so more of its half-million residents can switch away from gas stoves.
The New York City Housing Authority said Monday it expects this autumn to launch the Induction Stove Challenge, which will call on appliance manufacturers to design and build energy-efficient stoves that can operate on 120-volt/20-amp circuits.
Induction stoves typically operate on 220 volts and 40 or even 50 amps.
NYCHA’s 177,569 housing units typically are equipped with a gas stove and 120-volt line. Upgrading the electric wiring would be impossibly expensive, even if tens of billions of dollars’ worth of deferred maintenance costs had not already accrued in the authority’s 2,411 buildings.
NYCHA wants to replace gas ranges so residents can benefit from indoor-air quality improvements, and as part of larger building decarbonization efforts.
NYCHA is joining with the New York State Energy Research and Development Authority and New York Power Authority on the initiative. They will establish performance criteria and product specifications for the induction stoves, then expect to issue a request for proposals this year, and hope to select one or more manufacturers to design and test the new ranges.
Once testing is complete, NYCHA plans to pilot these lower-voltage stoves and induction-capable cookware in 100 units.
Eventually, NYCHA wants to remove gas stoves from all the buildings it owns, but initially it will aim for 10,000 apartments. It hopes this will be a broad-enough scale that other building owners and will see induction cooking as an affordable option and manufacturers will see the potential for a larger market.
To help build that demand pipeline, NYSERDA has hired the Building Decarbonization Coalition to engage other states and property owners on the project.
The Induction Stove Challenge follows a demonstration project that put induction stoves in 10 units of a NYCHA building in the Bronx.
The stoves were a hit with the residents, and indoor air quality improved. But the effort demonstrated the site’s limits, as well.
The appliances had to be dispersed throughout the building so as not to overload the circuitry — once one apartment got an induction stove, no units directly above or below could get one.
That’s why NYCHA is excited about the possibility of running induction stoves with the standard 120-volt wiring.
“If energy-efficient induction stoves can be redesigned to function in NYCHA buildings,” NYCHA CEO Lisa Bova-Hiatt said in a news release, “it sets an amazing precedent for what can be done with existing infrastructure, some forward thinking, and the necessary funding.”
The New York Public Service Commission on Monday petitioned the D.C. Circuit Court of Appeals to review FERC’s approval of NYISO’s proposal to use a 17-year amortization period in capacity auction demand curves (ER21-502).
NYISO proposed to move from a 20-year amortization period — the assumed time that a hypothetical peaking plant is expected to be operational — to 17 years in response to state legislation that set strict net-zero requirements that are forcing fossil plants to retire sooner.
After rejecting it twice previously, FERC accepted the ISO’s proposal in May on remand from the D.C. Circuit. (See FERC Accepts NYISO’s 17-Year Amortization Period Proposal.) The commission’s rejection had been challenged by the Independent Power Producers of New York.
“The unjustified shortening of the amortization period will needlessly increase capacity auction charges by hundreds of millions of dollars,” the PSC said. The commission’s decision “must be reversed because it fails to provide the requisite ‘reasoned analysis.’”
The ISO’s revisions were part of a suite of changes called the demand curve reset, which altered the assumptions and scope for capability years 2021/22 through 2024/25 to predict the volume of megawatts needed to meet demand.
Stakeholders discussed new proposals to revise PJM’s capacity market and discussed updates to the RTO’s risk modeling methodology during a meeting of the Critical Issue Fast Path (CIFP) process July 17.
The meeting included a second proposal from Daymark Energy Advisors and the East Kentucky Power Cooperative (EKPC) that would modify PJM’s proposal and a presentation from American Municipal Power (AMP) that suggested several changes to the Independent Market Monitor’s proposal.
Daymark CEO Marc Montalvo described its second joint package with EKPC as a trimmed-down version of the PJM proposal, with changes including retaining the annual Base Residual Auction structure instead of moving to a seasonal auction and preserving the fixed resource requirement structure. (See “Daymark and EKPC Propose Base and Emergency Capacity,” PJM Completes CIFP Presentation; Stakeholders Present Alternatives.)
While the proposal retains PJM’s proposed marginal effective load-carrying capability (ELCC) accreditation model, Montalvo said it’s not the preferred long-term solution for a forward market structure as more renewables come online.
The proposal would use an hourly reimbursement model that would pay resources for the capacity they provide in each hour of a delivery year, meaning they would offer their committed capacity into the real-time and day-ahead markets and follow dispatch. Generators would not be paid for their capacity for hours in which they do not do so.
Natural gas resources that have an offer in the markets but are called on too late to nominate for fuel according to the gas pipeline procurement timelines would retain their capacity commitment. Montalvo said the interaction between the gas and electric timelines are an operational issue and ensuring that dispatch doesn’t conflict would be PJM’s responsibility.
Resources would be able to engage in bilateral contracts to meet their capacity obligations and would be expected to do so when prolonged outages are anticipated.
Montalvo said the objective in drafting the proposal was to create a penalty framework that incentivizes performance without jeopardizing the viability of long-term resources when they’re assessed.
AMP Suggests Changes to Monitor Package
AMP’s Lynn Horning gave an overview of several changes the organization believes would build on the sustainable capacity market design proposed by the Monitor.
AMP has its own CIFP proposal that would create subannual accreditation and replace the Capacity Performance penalty construct with a reward and penalty system built around testing performance and providing “pay as you go” capacity payments. (See “AMP Seeks Subannual Accreditation,” PJM Stakeholders Refine CIFP Capacity Market Proposals.)
Horning said the Monitor’s proposal has the benefit of focusing on defining demand for each hour and matching that with adequate load. It also includes locational elements and simplifies the auction clearing process. She said the Monitor’s proposal to create a new accreditation model, the modified equivalent availability factor, also is preferable to PJM’s marginal ELCC approach because it avoids the latter’s interactive effects and improving the focus on real-time operations.
The changes to the Monitor’s proposal made by AMP include allowing natural gas generators to submit start, notification and minimum run time parameters on a shorter time frame based on pipeline conditions and to permit them to reflect a wider breadth of costs related to pipeline service in capacity or energy offers.
The AMP proposal also calls for retaining energy efficiency resources in the capacity market — the Monitor’s package would remove them — and differentiating the availability of demand- and supply-side demand response resources.
Planned capacity resources would be required to notify PJM if they plan to submit an offer in the BRA prior to the posting of the planning parameters for that delivery year, which has been a topic of stakeholder discussion since the absence of planned resources in the 2024/25 BRA was attributed to PJM delaying the release of auction results last year. Resources that do not indicate that they plan to participate in the auction would be permitted to offer only energy bids. (See FERC OKs PJM Proposal to Revise Capacity Auction Rules.)
AMP also called for a second CIFP phase to discuss holding BRAs closer to their associated delivery year, creating a subannual procurement system with time-of-day procurement assessments and exploring additional ways of creating comparability between the capacity market and FRR systems.
PJM Updates Risk Analysis Figures
PJM also presented updated reliability risk modeling figures, aiming to capture a broader range of threats to reliability and evaluate the differences between how an expected unserved energy (EUE) method of deriving the requirement would capture risk and the status quo loss-of-load expectation. (See PJM Continues CIFP Discussion of Seasonal Capacity Market Proposal.)
The new data pare back the preliminary findings PJM presented at the May 30 CIFP meeting, which showed a sharp shift in risk toward winter, particularly under the EUE model. While the new data still have risk concentrated in the winter, the season now makes up only about 64% of the risk under the baseline model, rather than the 96% in the preliminary data.
The presentation also included three additional models that include a longer historical weather lookback — going back 50 years instead of 30 — and two adding in climate change adjustments as well. The longer historical lookback increases the winter risk to 71%, but the two climate change variants both swing risk back to being predominantly in the summer.
Method A, which results in the higher summer risk, estimates the trend that climate change is having on seasonal minimum, mean and maximum temperatures to create adjustments that are applied to historical temperatures to consider how past weather would manifest under future climate conditions. Method B follows the same system, but only for mean temperatures.
AUSTIN, Texas — The National Association of Regulatory Utility Commissioners’ annual Summer Policy Summit attracted more than 1,000 state and federal regulators and their staffs; industry representatives; consumer advocates; and other stakeholders July 16-19 for discussions on understanding and preparing for the grid challenges that lie ahead.
NERC’s recent summer reliability assessment lent considerable fodder to the discussions, with its warning that extreme weather, plant retirements and transmission outages have made supply shortfalls more likely across much of the U.S. The report also stressed the need to maintain and expand a dispatchable baseload generation fleet to keep pace with the higher demands that electrification and climate change are placing on the grid. (See West, Texas, Midwest at Risk of Summer Shortfalls, NERC Says.)
Speaking on a panel discussing the reliability challenges, Stan Connally, Southern Co.’s executive vice president of operations, said shrinking reserve margins are complicating the task of balancing clean energy with affordability.
“Frankly, I think one of the risks as we move forward here is we let those priorities get out of balance,” he said. “It’s just important that we continue having these reliability conversations, because at the end of the day, and in these very, very extreme conditions, our customers need us to have the lights on. Air conditioning matters, right?
“Resource adequacy is a big deal. Shrinking reserve margins are something we have to pay attention to around resource adequacy,” Connally added. “We have an aging fleet. We also have a growing solar base. … Mixing that all together to ensure resource adequacy for the long term has to be center stage of our planning.”
Fellow panelist Stacey Doré, Vistra’s chief strategy and sustainability officer, said her company’s diversified fleet gives it a unique advantage in achieving balance between reliability, affordability and sustainability.
“We do see near-term reliability risks because we think that the projections show that thermal generation is going to be retiring at a faster pace than we can make up for with other assets in the long term,” she said. “We’re all trying to get to the place where we have enough carbon-free, reliable generation to replace those thermal assets … but the pace at which that is happening is not keeping up with the pace at which thermal assets are retiring.”
SPP COO Lanny Nickell said the transition to renewables and decarbonization will continue to take place, “whether or not you like it.” With clean energy goals set for 2050 and progress to be made by 2030, he said he used to be more worried about 2030 than 2050.
“Unfortunately, over the last several months, I’m no longer as worried about 2030 as I am about right now,” Nickell said. “Our analysis has indicated there’s a growing amount of risk that we can’t sustain. We’ve seen about 8,000 MW of thermal generation retired over the last seven, eight years. In that same time frame, we’ve seen about 24,000 MW of wind generation added. That sounds like a pretty good tradeoff. It hasn’t been, and our loss-of-load expectation studies that we have to perform every other year are indicating an increased risk associated with that transition.
“It may sound like we’re three Chicken Littles up here trying to scare everybody, but there are solutions. It’s just a lot of these solutions will take time to see the full effect,” he added.
Nickell reminded the audience that transmission is “an important tool in the toolkit” and offered resilience as an example. Instead of valuing transmission for its reliability and production cost savings through reduced congestion, he said, grid operators also should realize the importance of shipping energy across their seams.
“After Winter Storm Uri, we came to realize that resilience has got to be one of those measures,” he said, noting that when the storm took thermal resources offline in February 2021, SPP was able to meet 14% of its demand with imports from MISO and PJM. “We were importing on a transmission system that’s never seen this much energy flow across it … because we had strong interconnections throughout much of the East and to the West. That’s the value of resilience. It’s like insurance. You don’t really want to have to use it, but man, you’re thankful when you have it.”
Valuing Energy Efficiency
Speaking on a panel debating extreme weather’s reliability implications, former FERC and Texas regulatory staffer Alison Silverstein pointed out that energy efficiency doesn’t need to be accredited for effective load-carrying capability (ELCC) “because it doesn’t break down.”
She said that with an “intentional strategic demand response,” the industry will be able to take advantage of two areas that have “important synergistic effects” for the wind and solar fleet.
“With the right choices and energy efficiency and demand response, you are bringing down the peak overall,” Silverstein said. “With the amount that you need to fill in the evening as the wind is ramping up and the solar is dropping, you have less of a gap to fill out every hour. The more we can do to make our homes and buildings more energy efficient, the less we have to do in terms of that kind of ramping and the less vulnerable we are to the ELCC for this kind of thorough plan.”
Texas established the nation’s first energy efficiency resource standard (EERS) in 1999 by requiring utilities to achieve a specified amount of energy efficiency savings annually. It has since been leapfrogged by 26 other states and now has the weakest EERS in the country, according to a 2021 white paper by the American Council for an Energy-Efficient Economy.
Silverstein posited that the state’s roughly 4 million poorly insulated homes, more than a third of the total stock, is one reason ERCOT has been able to meet record demand this summer. (See ERCOT Demand Exceeds 82 GW for 1st Time.)
“It’s because 45% of Texans are low income and energy insecure. They are setting their thermostats at unsafe levels,” she said. “They are doing voluntary conservation of electricity, not because they’re trying to be good public citizens for the reliability of the grid, but because they can’t afford to consume enough electricity to stay comfortable. If they were able to consume more electricity, our demand would be significantly higher, and [ERCOT CEO] Pablo [Vegas] is going to be pacing the back of the control room.”
Remembering the 2003 Blackout
NARUC President Michael Caron, a commissioner on the Connecticut Public Utilities Regulatory Authority, kicked off the summit by moderating a panel marking the 20-year anniversary of the 2003 Northeast Blackout. The memories of that day still linger with the panelists.
“I think about this every day and before I go to bed at night, which explains the bags [under my eyes]. It was terrifying,” NERC CEO Jim Robb said. “I never thought I would be in the role that I am today.”
Texas Public Utility Commissioner Jimmy Glotfelty was on vacation camping with his family and several others in New Mexico, having just helped stand up an electricity office in the U.S. Department of Energy. Like other government officials, he left D.C. for much of the month. Fortunately, he had access to the camp site’s “communications center,” a closet with one phone and a fax machine.
“I spent the next two and a half days in that phone booth on phone calls with folks from NERC, our [National] Labs, folks from the White House and in Canada, trying to figure out how we would do this investigation, which we’ve never done before and had no real understanding of how to jumpstart it,” Glotfelty said. “We found the path forward that really started the Monday after the blackout, sending teams out to the utilities, out to the ISOs, to NERC, and put a plan together to really study what happened. So, we had all sorts of phone calls back and forth, and it was an interesting place to be for the biggest blackout in North American history.”
Suedeen Kelly was in FERC’s library the day of the blackout preparing for a Senate hearing on her nomination to be a commissioner.
“You felt disbelief at first and then shock and horror, and then a realization that I was soon to join an institution that was amazingly well prepared to try and do something about this,” she said.
An interim report identified the cause — a software bug that left operators unaware they had to shed load after transmission lines drooping into vegetation caused the initial outage — but did not make any recommendations. That came early in 2004 from an independent commission formed by President George W. Bush and Canadian Prime Minister Jean Chrétien.
The report team ran into a late roadblock when the Canadians said the final report had to be translated into French.
“‘How long will that take?’” Glotfelty remembered asking. “‘Three weeks.’ We said, ‘No way.’ We ended up getting support from the State Department, which translated the report in two days.”
The report and the Energy Policy Act of 2005 led to numerous changes in the industry. Most important, it gave greater authority to NERC to enforce standards that previously had been treated as guidelines. It also led to changes in how operators handled transmission outages.
“The greatest thing we did was shed load,” Glotfelty said, referring to ERCOT’s response during the 2021 winter storm that almost brought the Texas grid to its knees. “What happened in 2003 was the wrong action. System operators were scared to shed load. They figured they would get fired or their companies would get beat up by their regulators.
“In Texas, we did that. People still got fired, but we saved the system,” he added. “We saved 30 days of economic and human suffering by shedding load and making sure the transmission system stayed viable. So that was really an important understanding from the 2003 blackout.”
Asked whether the country might see another blackout like the one 20 years ago, Robb said, “I feel generally quite good about how the risks of 20 years ago were addressed.” Indeed, his organization’s recent State of Reliability report found that the North American bulk power system generally remains highly reliable and resilient.
“If you look at the performance of the electric grid as we define it from a reliability perspective, we have made substantial improvements, but the risk profile continues to grow,” Robb added, pointing to renewables’ growing share of the fuel mix. “We are working with our partners — NARUC, the gas sector, the technology sector — to try to figure out how we can solve these issues that nobody can solve with an edict. There’s been a lot of evolution of the model that was created, but I think we should all be extraordinarily [confident].”
Will EPA Rule Accelerate Change?
EPA’s recent proposed regulations to reduce carbon emissions from fossil-fired power plants under Section 111 of the Clean Air Act would set nationwide standards on plants based on whether they are new or existing, their fuel type, frequency of usage, capacity and how long they plan to operate. (See EPA Proposes New Emissions Standards for Power Plants.)
Naturally, the proposal has raised concerns within the industry.
“We are the reliability watchdogs for North America, and we don’t dissect the particularities of this rule,” said NERC’s Fritz Hirst, director of legislative and regulatory affairs. He compared his agency to the Night’s Watch, which protects the main setting of the television series “Game of Thrones” but holds no allegiance to any of the show’s feuding kings and lords.
“Our role was to provide this common good, but I think it is kind of obvious to say that this rule will continue to accelerate the pace of change,” Hirst said. “In NERC’s view, managing the pace of change is the central challenge for reliability.”
In the short term, natural gas will continue to be a primary fuel source, GridLab Executive Director Ric O’Connell said.
“Natural gas just a couple of decades ago was kind of a hobby fuel, right? It was the summer-peaking fuel,” he said. “Natural gas has really come from kind of the sidelines … now it is 40% of our electric generation. The electric system is the largest user of the gas system, and we haven’t really changed the way we contract and think about delivery of gas. It’s now a year-round baseload fuel, and in the winter, it’s really competing with other uses like heating.”
Emily Sanford Fisher, Edison Electric Institute’s executive vice president of clean energy, said with coal fuel’s use down to less than 20% of the nation’s fuel mix, non-emitting resources (renewables and nuclear) account for more than 40% of electricity consumption.
“The industry is in a different spot,” Fisher said, noting that about 50 of EEI’s members have made voluntary commitments to reduce their emissions to zero or net zero, albeit “not on the time frame that EPA puts out.”
“That means that we are generally in agreement about where the industry is headed, and this is really a question about pace and timing and the role of technology,” Fisher said. “Interestingly, all of the conversation in 2014-2015 was about coal. All of the conversation today is really about the role of natural gas, and that reflects this change in our generation mix. You can see from the rule that EPA is pretty concerned about our reliance on gas, and we’d like to make sure that it puts some bumpers around how much gas generation remains a part of our mix.”
Time is Now for Nuclear
One month after taking the stage during Edison Electric Institute’s thought leadership forum to promote nuclear energy’s role in a carbon-free future, Julie Kozeracki, a senior adviser with the Department of Energy’s Loan Programs Office, returned to Austin to highlight advanced nuclear reactors. (See “Nuclear Needs a Breakthrough,” Overheard at EEI 2023.)
Kozeracki said she has been leading a DOE initiative on nuclear commercialization that has resulted in a report, “Pathways to Commercial Liftoff: Advanced Nuclear.” It says advanced nuclear technologies, such as Gen III+ reactors similar to conventional generators and Gen IV reactors that use novel fuels, provide a “proven option” to supply the 550 to 770 GW of additional clean, firm capacity necessary to reach net zero.
“We see there being a need for 200 GW of new nuclear capacity, in addition to the roughly 100 GW we have operating today,” Kozeracki said. “That’s because in any decarbonization scenario, we see there being a need for upwards of 700 or 800 GW of clean, firm capacity. Because regardless of whether you build a ton of renewables or a crazy amount of renewables, you need some firm capacity to help balance the intermittency of renewable generation. And nuclear is one of the only options proven at scale.”
She put in a plug for small modular reactors, saying they can provide more certainty of hitting cost targets and likely will play an important role in the early scale-up. Kozeracki said commitments for new nuclear are needed as soon as possible.
“The time to start on that was yesterday,” she said. “The choices in front of us are not between new nuclear, which could feel risky or expensive, because your other options are also going to be risky and expensive. It’s really important to recognize that nuclear has a vital role to play in getting to decarbonization at scale, and anything we can do to start those conversations and those decisions sooner is going to be really critical for getting us on the path there.
“Everyone keeps saying that they want to be fourth, and they would like someone else to go first, second or third. But you can’t have a fourth reactor if folks don’t sign up for one, two and three.”
Arizona’s decision to join the U.S. Climate Alliance could rev the state’s clean energy economy, some observers said, but others warned that politics could get in the way.
Gov. Katie Hobbs (D) announced this month that Arizona has joined the Alliance, a coalition that includes 23 states, Guam and Puerto Rico. Alliance members promise to pursue policies to reduce climate pollution and promote clean energy deployment.
“Together, we are creating green jobs and businesses, ensuring clean air and water for Arizonans, lowering energy costs and preparing more effectively for a changing climate,” Hobbs said in announcing the move.
Hobbs’ announcement came around the time Gov. Joe Lombardo withdrew Nevada from the Alliance, citing conflicts with the state’s policy of developing a diverse energy portfolio that includes natural gas. (See Nevada Exits US Climate Alliance.)
Michael Barrio, a senior policy principal at Advanced Energy United, highlighted the potential economic benefits of Alliance membership for Arizona. AEU is a business association aimed at achieving 100% clean energy in the U.S.
By joining the Alliance, “we’re really opening the doors to investment,” Barrio told NetZero Insider.
Businesses are attracted to states with a stable and predictable clean energy framework, Barrio said. He noted that a growing number of businesses — including large companies such as Meta — are making clean energy commitments.
“Arizona is signaling that this is a state where those kinds of commitments can be fulfilled,” Barrio said.
Attorney Court Rich, director of the Regulatory and Renewable Energy Department at Scottsdale-based Rose Law Group, said clean energy and related technology represent a “massive” economic opportunity for Arizona. Hobbs has sent a strong message of support by joining the Alliance, Rich said.
“But given state politics, and a GOP-controlled legislature and utility commission, we need everyone on board to make sure Arizona maximizes its potential to be a leader in the clean energy economy,” Rich told NetZero Insider.
“At the end of the day, I would be surprised if joining the Alliance has any impact on Arizona’s actions on emissions,” he added.
Arizona already is making clean energy-related economic progress. A report this year from Climate Power, a strategic communications organization, found that investments in clean energy projects led to 12,720 jobs in Arizona from the time the Inflation Reduction Act became law in August 2022 through March 2023.
Among 191 new clean energy projects nationwide, the report pointed to LG Energy Solution’s plans to build a $5.5 billion battery manufacturing complex in Queen Creek, Ariz., where it will make batteries for EVs and energy storage systems.
States Working Together
U.S. Climate Alliance members take action through steps such as adopting climate action plans, setting zero-emission vehicle standards and developing building performance standards. Hobbs’ office didn’t respond to requests for details on the administration’s next steps regarding climate change.
Diane Brown, executive director of the Arizona Public Interest Research Group, said Hobbs and her newly created Office of Resiliency have “hit the ground running” in terms of pursuing federal funds for clean transportation and clean energy and working with a wide array of stakeholders to address climate change and its impacts.
Membership in the U.S. Climate Alliance will give Arizona a chance to collaborate with other states on best climate practices, Brown said.
“The result of developing and implementing strong climate change mitigation policies will not only reduce climate pollution, but can save consumers money, protect air quality and promote public health,” Brown told NetZero Insider.
Beyond Pledges
Another commitment from Alliance states is to reduce net greenhouse gas emissions by at least 26% by 2025 and 50% by 2030, as compared to 2005 levels, and reach net zero by 2050.
A report this month from the Environmental Defense Fund (EDF) looked at the impact on national climate progress of 24 Climate Alliance states hitting their 2025 and 2030 targets.
Hitting the state targets would reduce by 43% the national emissions gap — the difference between projected emissions and a Biden administration goal to cut nationwide emissions by at least 50% by 2030, the report found.
In updated figures provided to NetZero Insider last week, factoring in Arizona’s membership in the U.S. Climate Alliance and Nevada’s withdrawal, EDF found that the national emissions gap would shrink by 44% if states reach their targets.
But many states are struggling to meet their commitments, the report found. The 24 states in the report are on track to collectively reduce net emissions by 20 to 23% by 2025, short of the 26% target, and by 27 to 39% in 2030, compared to the 50% reduction target.
Pam Kiely, EDF’s associate vice president for U.S. climate, said governors “must drastically step up ambitious and comprehensive policies to cut pollution in line with their goals.” And the Inflation Reduction Act gives them an opportunity to do so, Kiely said.
“Generating that collective impact requires moving beyond just pledges — governors have to deliver on their promises,” Kiely said.
The state most heavily dependent on home heating oil is making significant strides in its campaign to get electric heat pumps in more homes.
Maine Gov. Janet Mills (D) said Friday that 104,000 of the systems have been installed with help from a series of initiatives begun after she took office in 2019.
The goal had been 100,000 by 2025, so she set a new goal: 175,000 additional heat pumps by 2027. Success would mean a significant portion of the state’s 750,000 housing units had at least partially decarbonized.
Maine is a state that would seem at once ideally suited and highly challenging for heat pumps. Few areas have natural gas distribution infrastructure and only 1 in 13 households use it as the primary heating fuel, according to the U.S. Energy Information Administration. As a result, about 60% of Mainers heat with oil as of September 2022, more than any other state.
Air-source heat pumps are less expensive to operate than oil furnaces and can have a lesser impact on the environment. But there is some lingering skepticism in the public mind about their efficacy during cold snaps, and Maine is one of the coldest states in the nation.
The Maine Energy Marketers Association, whose members sell all manner of fuels, is trying to ensure the public is aware of the potential shortcomings of heat pump technology.
However, state residents seem to be voting with their pocketbooks: The number of heat pumps installed statewide has climbed from about 40,000 in 2019 to roughly 145,000 now.
Mills’ office said Friday that heat pump rebates through Efficiency Maine and a low-income heat pump program at MaineHousing have been instrumental in getting the technology installed in the state’s residential and commercial structures.
Efficiency Maine pitches federal tax credits to accompany the state rebates for installation. Together with savings on operating costs, a homeowner can recoup the purchase cost in as little four to six years, the program’s website says, depending on whether they qualify for a low- and moderate-income adder.
Efficiency Maine does, however, warn that a fuel-burning backup system is needed in temperatures below minus 15 degrees.
Legislation Mills signed in 2019 to encourage and subsidize property owner adoption of heat pumps was accompanied by another important effort: development of a workforce to install all those heat pumps.
The state’s community college system expanded its heat pump training courses and has trained 558 technicians to date.
The heat pump campaign is part of a larger effort by Maine to fight climate change. Mills last year signed a law setting the goal for carbon neutrality as 2045 and this year proposed moving the 100% clean energy target date from 2050 to 2040.
Clean energy is important to the climate impact of heat pumps. As the Maine Energy Marketers Association points out, heat pumps are not as green as they seem if the electricity that powers them comes from burning carbon.
White House National Climate Adviser Ali Zaidi joined Mills for her announcement Friday.
“Maine is paving the way for states across the country seeking to build a clean energy future that protects our climate and creates good-paying jobs for all Americans,” he said in a news release.
Mills added: “Our transition to heat pumps is creating good-paying jobs, curbing our reliance on fossil fuels and cutting costs for Maine families, all while making them more comfortable in their homes — a hat trick for our state.”
New York took strong first steps to comply with climate and energy legislation mandating that it reduce its emissions and decarbonize its economy, according to a preliminary review released last week (22-M-0149).
The Department of Public Service gave an upbeat impression in its first annual progress report on New York’s compliance with the Climate Leadership and Community Protection Act of 2019.
“New York State has invested a great deal in its initial efforts to realize the clean energy growth and emissions reduction goals of the CLCPA,” reads the DPS’s conclusion.
Overall emissions reductions | NYDPS
According to the report, New York’s overall emissions production was reduced by 49,499,299 metric tons of carbon dioxide from 2020 to 2022. Mostly this was due to fossil fuel displacement, but it is increasingly being offset by EVs.
The New York State Energy Research and Development Authority during this time collected $1,871,922,708 through its renewable energy credit programs, and 95,937,409 MWh of clean energy was produced from load-serving entities procuring RECs, which contractually obligate generators to deliver certain amounts of renewable energy.
Statewide energy benefits | NYDPS
These are positive signs for New York, since the CLCPA is ambitious: 70% renewable electricity by 2030, 100% zero-emission electricity by 2040 and net-zero emissions statewide by 2050. The policy also mandates the state procure at least 6 GW of solar energy by 2025, 3 GW of storage resources by 2030 and 9 GW of offshore wind by 2035.
The report added that the CLCPA necessitated “an extensive restructuring of the existing grid,” which has driven renewed investment into both upgrading antiquated lines and adding more resilient lines that can tolerate greater voltage conditions from more advanced technologies.
The DPS also highlighted New York’s initiative to decarbonize not only the larger barriers to net zero, but also other critical sectors like transportation and housing, and the DPS commended the state’s actions to promote disadvantaged communities, such as obligating them to receive at least 35% of all decarbonization investments. (See NY Climate Justice Panel Sets Disadvantaged Community Criteria.)
Despite this relatively rosy assessment, New York risks not meeting its goals, given how NYISO reports predict future reliability shortfalls that may require emissions-producing peaker plants to operate past their expected retirement. (See NYC to Fall 446 MW Short for 2025, NYISO Reports.)
These reservations were seen at the DPS’s monthly meeting, during which the inaugural report was delivered and discussed, and several commissioners voiced concern about future costs and reliability. (See “CLCPA Update,” Energy Transition Costs Give NY Utility Commissioners Pause.)
The DPS report calls on state agencies, including itself, to be “more transparent to the public” about its CLCPA compliance to help New York stay on track to achieve a decarbonized economy by 2050. The agency promised to improve its scoring guidance and data reporting criteria (14-M-0094).
Clean Energy Progress
The DPS’s first report card on New York’s CLCPA compliance had useful metrics to show the state’s progress:
66% of New York’s projected 2030 electricity is covered by renewable energy projects that already are operating, contracted or awarded.
46% reduction in statewide emissions produced from electricity and 7% reduction in gross emissions between 1990 and 2019, according to the Department of Environmental Conservation.
1% of the renewable energy standard obligations were met by LSEs, while 99.8% of LSEs under PSC jurisdiction met their RES obligations in 2021 (15-E-0302).
5% of the zero energy credit obligations were met by LSEs, while 99.8% of LSEs under PSC jurisdiction met their ZEC obligations in 2021 (15-E-0302).
5,999 MW of solar resources are either committed or completed as of November 2022, according to the NY-Sun midpoint review, and the NY-Sun program is on track to spend $200 million on projects by 2025 (21-E-0629).
1,301 MW of energy storage resources has been awarded or contracted as of October 2022, which represents 87% of the 2025 target (18-E-0130).
~12,000 MW of proposed ESRs are circulating in New York’s distribution-level or wholesale-level interconnection queues.
144,037 EVs were registered in New York as of May 2023, while 8,002 level two and 1,215 direct current fast charging ports were serving the state’s fleet, according to EValuateNY.
MISO has enacted conservative operations orders, a hot weather alert and a capacity advisory for its Midwest region ahead of the season’s first widespread heat wave set to bake much of the U.S. this week.
The grid operator said a combination of hot weather and load forecast uncertainty is forcing a conservative operations declaration Tuesday through Friday for MISO Midwest. The capacity advisory is effective beginning Wednesday “until further notice,” per MISO.
The National Weather Service anticipates dangerous heat that has been simmering in the West, Texas and Florida will expand this week into the eastern two-thirds of the country, starting in the north-central states and Plains.
MISO has asked its generation and transmission owners to consider revoking or deferring maintenance outages. It also has asked generation owners to notify it of any fuel restrictions and environmental limitations of equipment. MISO said members should be prepared to enter maximum generation emergency procedures, which involve calling on load-modifying resources.
Spokesperson Brandon Morris said MISO and members are preparing for the extreme heat, which could drive 2023’s annual peak demand in the footprint.
“The potential for higher-than-normal demand and tight operating conditions could lead to a system peak for the year. MISO issued alerts and advisories in anticipation of the heat wave to provide situational awareness and notify our members’ utilities to prepare in case additional actions are needed to ensure reliability,” Morris said in an emailed statement to RTO Insider. “We are coordinating with our neighboring grid operators who expect similar conditions. Because of our large, diverse footprint, MISO has several options to obtain power and send it to where it is needed.”
Ahead of the season, MISO predicted July would hold its greatest chance of enlisting the help of its load-modifying resources and leaning on neighbors for exports during blistering temperatures. (See MISO: Little Firm Capacity to Spare This Summer.)
MISO last issued conservative operations instructions in late June, when it struck a rough patch of storms and hot temperatures that also spawned capacity advisories and hot weather and severe weather alerts June 22-30. The RTO also issued a hot weather alert July 19-20 for much of its South region.
AUSTIN, Texas — Texas commissioner Will McAdams, chair of SPP’s Resource and Energy Adequacy Leadership (REAL) Team, set the tone from the outset when he shed his blazer and rolled up his sleeves as the group gathered for its meeting Wednesday.
“It’s July in Texas. Let’s get started,” he said.
For the next nine hours of what McAdams called a “crusher” of a meeting, the REAL Team discussed issues ranging from flexibility and ramp associated with capacity obligations to maintenance outages and their effect on capacity obligations. A central theme emerged around how SPP compensates load-responsible entities for availability or penalizes them for lack of availability during critical hours.
“It’s a lot of ships that we hope are moving in the same direction now, but it’s a lot to coordinate,” McAdams told fellow commissioners during an open meeting the following day.
The team met its first objective when it endorsed a winter resource adequacy requirement (RAR) approved recently by the RTO’s Markets and Operations Policy Committee. The revision request (RR549) will go before SPP’s state regulators and its Board of Directors this week for final consideration. (See “Members Endorse Winter Resource Adequacy Requirement for 2024-25,” SPP Markets and Operations Policy Committee Briefs: July 10-11, 2023.)
The measure applies the same level of validation, study and assessment requirements to the winter season (December through March) that is applied to the summer season, including a deficiency payment for capacity shortfalls. It also assigns an annual deficiency payment to prevent duplicate payments for the same capacity within an annual timeframe.
RR549 is not without its detractors. It barely met MOPC’s approval threshold and cleared the REAL Team with two votes to spare, 9-5. Members removed one of two revisions added during the MOPC discussion over confidentiality concerns.
The measure is effective for the 2024/25 winter season (December through March).
“It was a hairy deal,” McAdams told the Texas Public Utility Commission. “It’s a real shootout. Just trying to provide the mechanisms that ensure resource adequacy is not an easy thing. These are not easy decisions.”
SPP’s board and state regulators created the REAL Team, comprised of 14 independent directors, members, and regulators and their staff, earlier this year. The team has been meeting every three weeks since May. (See SPP’s REAL Team Swings Into Action.)
“I think the REAL Team is a bit of a fusion center,” McAdams told RTO Insider after the team’s first in-person meeting in May. “It’s bringing together corporate members, components of the Members Committee, the stakeholder components of SPP together with [Regional State Committee] leadership as well as board leadership … so that topics can be flagged and, frankly, polled to a degree in terms of resistance to certain staff recommendations and or support.”
The team has created sub-groups focused on resource adequacy, markets and operations. They will lean heavily on the Supply Adequacy Working Group (SAWG), which has primary responsibility for nine of the 11 objectives assigned to the REAL Team.
Its next milestone comes in October, when it plans to consider a ramping capacity requirement, begin addressing the footprint’s need for reliability attributes in the resource mix and endorse tariff changes — RR554 and RR568, respectively — that codify performance-based accreditation (PBA) and effective load carrying capacity (ELCC) policies.
The SAWG is developing both tariff revisions. It has created limitations for catastrophic exemptions that apply to all resource types that will sunset after 10 years of historical data from the units. The working group also has simplified the ELCC tiers by using a two-tiered approach with firm and non-firm transmission service.
More important, the SAWG has prepared a system methodology for upcoming loss-of-load expectation and ELCC studies that evaluates the collective reliability contribution of all ELCC resources to ensure they are correctly accredited.
SPP is responding to FERC’s recent order admitting it had mistakenly approved the RTO’s proposal to use an ELCC methodology to accredit wind and solar resources based on historical performance. The commission has granted renewable developers a rehearing of its original order. (See FERC Grants Rehearing of SPP Capacity Accreditation Proposal.)
The grid operator’s Market Monitoring Unit said it had equity and accountability concerns over the PBA and ELCC. It recommended measuring individual performance in the PBA process against the top 3% net peak load and including all outages, whether forced maintenance or out-of-management control, in the accreditation processes.
The MMU offered two recommendations it said would improve reliability that left one commission staffer shaking his head: the PBA measurement against the top 3% net load and implementing a true-up process at the end of each season.
Keith Collins, vice president of market monitoring, shared an event his team picked up just before July 4, when SPP had issued a resource advisory and then a conservative operations call. He said the MMU became aware of several hundred megawatts of resources, accredited for the summer, that were on outages because of staffing issues.
“They were aware … that whatever they were going to do was going to be accounted for in performance-based accreditation, and they did it anyway,” Collins said. “If we want to think of the incentives and what we’re doing to keep people from making those decisions and contributing to a reliable system, particularly when we need it the most, then we’re not there yet — because they did it anyway.”
SPP’s continued integration of renewable resources over conventional or thermal resources has created operational uncertainty and shortened the staff’s ability to commit resources, according to C.J. Brown, director of system operations. On Sunday, the RTO issued a resource advisory because of high loads, load and variable energy forecast uncertainty, and resource outages; it is at least the sixth resource of conservative operations advisory SPP had called since April.
“Those are very challenging and stressful situations,” he said. “You feel like every one thing you give up could put you into a situation where you’re not able to cover a certain percentage of uncertainty. We have to do that leading up to and including real time, and that starts as much as seven days out. Typically, about four days out is our longest lead time when a decision has to be made, but that’s just a continual process these days.”
“Two years ago, we might have made that decision two or three times a year,” Brown added. “Now it seems like it’s every other week.”
To maintain current levels of capacity until sufficient resource adequacy measures are in place, staff are developing policies — likely including some form of system support resource or reliability must-run contracts used by other grid operators — that “strongly encourage” generation owners to reconsider and postpone retirements. Based on utilities’ integrated resource plans and information gleaned through the transmission process, SPP expects 6.5 GW of gas- and coal-fired resources to retire by 2030.
The problem is compounded by hints of reluctance from renewable developers about investing in an RTO where conventional resources are retained.
“What we’re hearing is some of the recommendations and activities we’re making in the SAWG space and in the REAL space might be shifting renewables to other more profitable regions,” Casey Cathey, senior director of grid asset utilization, told the REAL Team. “Are we defining the requirements at a razor’s edge to where we’re just maintaining the fleet and barely improving? I think we need more markets, we need more carrots to be able to better optimize over a longer time horizon so the LREs can kind of appreciate what kind of supply we actually better recognize … we want to make sure we’re sending the right signal that if we are retaining our conventional fleet, that we have a path forward, because right now it seems like there’s a whipsaw.”
SPP’s generator interconnection dashboard indicates solar resources account for 43% of the projects in the GI queue (45.6 GW of 105.5 GW), followed closely by wind (26.1 GW, 24.8%) and battery storage (19.9 GW, 18.8%). Cathey said solar requests exceeded those for wind for the first time earlier this year.
“We can’t wait [for the solar]. We’ve had 250 megawatts of installed solar for a long time, but we have just not seen that build,” he said. “We’ve been thinking for about six to seven years that this might be our next frontier. Wind is highly volatile, it can be helpful, but a lot of times when wind winds down, solar’s actually doing pretty good.”
Cathey said the potential 90 GW of solar, wind and batteries in the queue doesn’t give him “a lot of comfort,” however.
“If we installed all gigawatts of wind, solar and batteries and we also retired a good portion of our conventionals, we would still have C.J. describing some slides of some conservative operations, and so we need to be balanced here,” he said. “Hopefully, a lot of this gets built but we also need to make sure we’re sending the right signal to either keep resources, conventionals, online for a period of time until another technology can take over.”
RA Forum Draws Industry Interest
The REAL Team will hold its next in-person meeting Sept. 8 in Dallas, the day after SPP hosts a Resource Adequacy Summit at DFW International Airport.
What started as a meeting limited to 75 attendees has blown up into an industry event that has drawn the interest of at least two FERC commissioners, according to organizers. NERC’s and EPRI’s CEOs, Jim Robb and Arshad Mansoor, respectively, have accepted invitations.
“There’s heavy interest nationally to provide forums where the reliability standard concept can be discussed on a national basis, what that involves and what defines resource adequacy, not just within ISOs but regionally,” McAdams said.
SPP has extended invitations to its neighbors, with MISO already accepting. ERCOT also has been invited to attend.
Even without ERCOT, Texas will have a heavy presence. McAdams said PUC staff will attend and energy consulting firm E3 will discuss valuing availability. E3 proposed an LSE reliability obligation construct and several other market designs for the Texas grid operator following the disastrous and deadly 2021 winter storm.
SPP has secured a larger meeting space than originally planned to handle the increased attendance.
NYISOupdated the Operating Committee on Thursday that 89 MW of nameplate behind-the-meter solar was added onto the grid in June. The month’s peak load was 22,867 MW and the minimum was 11,999 MW.
Mark Younger, president of Hudson Energy Economics, referred to the growing megawatts of energy storage resources in New York and asked what percentage of them can sell capacity resource interconnection service. (See “May Operations Report,” NYISO Operating Committee Briefs: June 22, 2023.) CRIS rights are needed to take part in NYISO’s capacity market and can be obtained either through a transfer from a facility with existing rights or from ISO deliverability studies.
Aaron Markham, NYISO vice president of operations, responded, “I believe only half is available to sell capacity.”
Matt Cinadr, a power systems operations specialist with The E Cubed Co., asked whether NYISO has observed any issues with intermittent production and the amount of reserve fuel available.
Markham said, “we’ve definitely seen the levels of intermittent production increasing the volatility on the system, but at this point, it hasn’t been a driver of any reserve shortages.”
“As the amount of intermittents increases, however, I think we’re definitely going to see greater magnitudes of error and need to procure some market products to help manage that going forward,” he added.
DER Manuals
The OC also approved six revised manuals presented by NYISO that will support the implementation of distributed energy resources in New York’s markets.
These DER manuals include revisions to market procedures like ancillary services, control center requirements and emergency operations, and have been reviewed by all other applicable working or stakeholder groups. (See “DER Manual Updates,” NYISO Discovers Market Problem, Opens Confidential Investigation.)
NYISO still anticipates these approved manuals will become effective in parallel with other related DER tariff and market models.
