NY Won’t Meet Renewable Target, Industry Says at Summit

ALBANY, N.Y. — Industry speakers at the 2024 New York Energy Summit told attendees the state has already missed its goal of 70% renewable energy by 2030 even as state officials maintained their optimism. 

Attendees at the Infocast event April 8-10 keyed on New York having some of the nation’s highest clean energy targets and a tough environment for reaching those milestones, which includes 100% zero-emissions electricity by 2040. 

Less often mentioned is that the state is starting from a low baseline, has not estimated cost or fully identified a source of funding for the transition, pledges to give full consideration at every step to fractious stakeholders and has a constitution that empowers local governments to slow or block progress. 

This dichotomy was a frequent point of discussion at the three-day event. 

State officials at the summit spoke of the importance of the looming 70-by-30 milepost, but not about the likelihood of reaching it. 

Private-sector attendees were not so reticent. 

Timothy McClive, director of energy policy and regulation at Central Hudson Gas & Electric, pointed to the math. 

“Renewable has to go from 25% currently up to 70%,” he said. “That would require about a 90 to 95% reduction in the amount of power coming out of gas and oil plants by 2030. That is a huge lift.” 

At the start of a discussion on ramping up onshore wind and solar development, one panelist after another said 70-by-30 is out of reach. 

“We won’t hit it,” said Paul Curran, chief development officer of CleanCapital, “but I don’t think that’s a bad thing, because we’ll have a goal, and the goal is aspirational.” 

“The resource that we don’t have a lot of right now is time — we’re out of time. Everybody is just managing time, and we’re not doing it very effectively right now,” said Keith Silliman, chair of the Alliance for Clean Energy New York’s board. 

“I don’t think we have a large enough labor pool to build that many megawatts in the six construction seasons we have left, and there’s not enough transmission capacity,” said Stephane Desdunes, vice president of grid-scale power development at EDF Renewables North America. He predicted the state would be able to contract the renewables by 2030 but not get them built by then.

But time is not the only hurdle. 

“There are a lot of issues in New York that we have not thoroughly thought out on this clean energy transition,” said Gavin Donohue, CEO of the Independent Power Producers of New York (IPPNY), whose members provide more than 75% of in-state power generation. 

John O’Leary, the state’s deputy secretary for energy and environment, acknowledged industrywide challenges. Contracts totaling more than 10 GW of renewable capacity were canceled in New York as the terms became untenable in 2023. But the projects themselves were not canceled, and many were bid into the expedited solicitation process that followed. 

“I’m confident that the rapid rebid process that is underway with [the New York State Energy Research and Development Authority] will yield projects that can move forward into construction around the state this year. I’m very excited about that,” O’Leary said. “It’s no question that renewable energy has been dealt some major setbacks and experienced a market reset in the past two years, but we are navigating through these challenges.” 

NYISO CEO Rich Dewey told RTO Insider the state presents advantages and challenges to the grid operator. 

“Cost allocation in the multistate jurisdictions tends to be the really contentious issue that ends up bogging down a lot of projects, and the failure to agree on that tends to be the death of a lot of them,” he said. 

“In New York, being a single-state ISO, it’s a much easier task. You still have the upstate-downstate [split] — exactly which customer is going to pay [and] who really benefits, and there’s a careful consideration of that — but I think it definitely makes it easier,” Dewey said. “It’s probably the biggest reason we’ve been so successful with our FERC Order 1000 projects so far.” 

On the flip side, New York has a strong home-rule tradition, and local governments are not shy about exercising it. 

“Siting is hard,” Dewey said. “Siting specifically downstate is much more difficult because of the geography and the nature of the population density. A lot of jurisdictions have local opposition to certain types of development projects.” 

The state’s creation of the Office of Renewable Energy Siting has helped streamline this process, Dewey added, but not smoothed out all bumps. 

Local Opinion

ORES has a delicate choreography to perform: usurping local authority on large-scale projects while still incorporating local input and meeting all the state mandates placed on renewable energy development. 

“For folks here in this room that have built or developed large-scale renewables in New York state, they know that [it’s] more than science, it’s art,” ORES Executive Director Houtan Moaveni said. “It is not easy; it is very challenging work; and it takes a lot of commitment to balance multiple issues at the same time in a parallel path.” 

One after another, speakers raised the same point as Dewey: local opposition to renewable energy construction. 

New York Solar Energy Industries Association Executive Director Noah Ginsburg said small-scale developers wish for something like ORES. 

“We really see New York favorably, based on the sustainability and longevity within the market that we believe exists,” said Zachary Muzdakis, director of market development for Madison Energy. “I think there’s a few areas where we can target improvement,” naming punitive local zoning restrictions and moratoria, and a desire to place generation closer to load centers. 

Dan Voss, senior director of project management at Kearsarge Energy, said New York is a great market. While interconnection has been an issue in other states, siting is the bigger challenge, he said. “We’re finding some inconsistencies from a permitting perspective. Moratoriums, they’re difficult. We’re fortunate to be able to play the long game, but many developers can’t do that.” 

Other Observations

CleanCapital’s Curran said the specificity of New York’s mandates and the commitment behind them have their own benefits. 

“When you go to a bank and you talk about a New York project, they understand what VDER [Value of Distributed Energy Resources] means; they understand the goals going forward,” he said. “Having certainty is an enormous help when you’re trying to explain what you’re trying to do. And that’s a big advantage New York has over other places in the country.” 

ACE NY’s Silliman said he appreciates the commitment of New York’s agencies promoting or enabling clean energy construction but wishes they had greater coordination and a better understanding of how their individual roles fit into the larger whole.

Richard Bratton, director of market policy and regulatory affairs at IPPNY, said New York has some of the strongest climate mandates in the nation, but that is not enough to foster the renewable energy development the state wants. Developers also need to see market price indications that the private sector can profit. 

Joshua Feldman, vice president of investments at Generate Capital, made the case for state and local incentives for projects. 

“It is important for the state of New York to consider the fact that this is true everywhere in the United States and that we are essentially faced with this decision on a recurring basis of, is New York state the best place for us devote our capital? And New York is not the easiest place to do business in. I think having local incentives to make sure that the industry stays focused on New York is critical.” 

John Howard, whose term on the New York Public Service Commission recently ended, said the state’s interconnection queue is better than most. “While it is a nightmare everywhere else, it is some nights just a bad dream here.”

Summit Attendees Receive Updates on NY Renewable Energy Efforts

ALBANY, N.Y. — Development of potential fossil fuel replacements was a recurring focus of the 2024 New York Energy Summit. 

Presentations at the Infocast event April 8-10 focused on alternate energy sources individually and collectively. 

Offshore Wind

Offshore wind is potentially one of the largest components of New York’s energy transition, with multiple wind farms envisioned to provide several hundred megawatts each of emissions-free electricity. 

But it is also the most problematic, relying on limited or nonexistent domestic manufacturing capacity and infrastructure and getting buffeted by macroeconomic trends. The state’s roster of contracted offshore projects was all but erased as rising costs rendered the contracts untenable in 2023, guaranteeing that already huge costs will jump even higher. 

The most recent provisional contract awards carry a weighted average all-in lifetime development cost of $150.15/MWh. (See Sunrise Wind, Empire Wind Tapped for New OSW Contracts.) 

However, with each project carrying a budget in the billions, and billions more in ecosystem investments expected, industry interest is keen. New York’s offshore wind reset was a topic through multiple presentations at the summit. 

Gregory Lampman, offshore wind director for the New York State Energy Research and Development Authority, reaffirmed what is widely known: New York remains fully committed to offshore wind, not just as a source of carbon-free electricity, but as a new industry with its own ecosystem. It just may take longer than expected to come to fruition.

“I think we’re all realizing that our aspirations and the goals and timelines that we had in mind were pretty exceptional,” he said. “The goals are still really massive, and we’re on track to do some really great things over the next couple of years.” 

Adaptation will be key, Lampman said. The state cannot just write contracts for projects; it must work with industry to move projects forward. 

Peter Lion of NYSERDA and David Whipple of Empire State Development said the state’s willingness to provide seed money — with more than $1 billion in grants — has helped advance the new sector. 

“Private industry is unable to do this on their own, from what we’ve seen, and New York is happy to be a public investor,” Lion said. 

Rubiao Song, managing director of energy investments at JPMorgan, said that from a tax equity perspective, the top concerns for investors are supply chain constraints, shortage of vessels and lack of a robust insurance market. 

“Hurricane risk is a real issue here,” he said. “We need a significant presence from the insurers.”  

Sergio Garcia, executive director of project finance in the Americas for Rabobank, said he believes the wind energy projects proposed off the New York coast will obtain their needed financing. 

“I think the expectations have to change a little bit. They’re not going to be financed the same as Vineyard Wind,” he said, referring to the 800-MW facility being built off Massachusetts, which in 2023 became the first major U.S. offshore wind project to put “steel in the water.” 

“I think at that point, banks were overly excited [and] extremely optimistic, and we saw what happened.” 

Yet the willingness to finance these projects endures, Garcia said, despite the slow pace of development and dearth of critical infrastructure such as ports and ships. “It’s not as fast as we would like it to be, but yes, there is appetite for those types of assets.” 

Aude Schwarzkopf, Equinor’s East Coast head of commercial development, said an important piece of infrastructure began to take shape in April as construction started on an offshore wind operations and maintenance port at the South Brooklyn Marine Terminal. Equinor is developing the site for its Empire Wind project but intends it to be a resource for other projects as well. 

“From the developer perspective, 2023 was hell, so it can only get better from here,” Schwarzkopf said. “At least that’s what I hope.” 

Equinor started 2023 with three contracted New York projects and ended the year with none, she explained. But in late 2023, Empire Wind was greenlit by federal regulators, and in early 2024, it won a conditional new contract from New York state. 

“I think that this more stable time is the time that the industry needs to focus on building the supply chain,” Schwarzkopf said. 

Brian O’Boyle, director of transmission development at National Grid Ventures, spoke of Community Wind, his company’s joint venture with RWE. It’s in a much earlier stage than Empire Wind, so it has a long road ahead.  

“I think we’re holding the course” in the face of the industry’s challenges, O’Boyle said. “A lot of it is building the supply chain up more than it is building the individual project, which in itself is a herculean undertaking.” 

Fred Zalcman, director of the New York Offshore Wind Alliance, said some momentum has been lost: Almost every East Coast state with offshore wind contracts saw cancellations in 2023. 

“Is it fatal? No. Absolutely not. And I think in large measure the credit goes to state policymakers,” Zalcman said, noting that NYSERDA took just three months to issue a rush solicitation for offshore wind proposals after existing contracts became untenable in 2023. 

New York’s three previous solicitations had taken 14 months on average to prepare. 

Solar

Discussion of solar energy development at the summit veered between appreciation for New York’s support of community solar projects and dismay at increasing local opposition to construction. 

Nicola Armacost, mayor of Hastings-on-Hudson in Westchester County, discussed the village’s success streamlining its solar permitting process. It is hardly a microcosm of New York state — a small, progressive-minded village with many preservationists among its populace — but the process has helped it gain recognition as a clean-energy community. 

“There isn’t a lot of resistance on either the residential side or on the municipal side, and I think that makes it much easier,” Armacost said. 

Not so in other parts of the state. Resistance to solar and other renewable energy installations is firm, and it is spreading. 

Noah Ginsburg, executive director of the New York Solar Energy Industries Association, said he asked his members to identify municipalities that have enacted restrictions, then had to send out another email telling them to stop because he had enough names to make his point.

“Mayor Armacost, please come and run for mayor in many other towns across New York state that are banning solar,” he said. “It’s easier in many parts of New York state to get a permit for a 100-MW solar facility than a 5-MW solar permit.” 

Solar installations of less than 5 MW have been the majority of those installed in the state and are the majority of those proposed, he said, but they do not qualify for the expedited review the state Office of Renewable Energy Siting provides to larger projects. 

A subset of small solar installations — community solar — has done very well in New York thanks to supportive state policies. In 2023, the state surpassed 2 GW of installed community solar, the most of any state. 

Max Joel, director of NY-Sun at NYSERDA, said the state is on track to meet its distributed solar targets: 6 GW by the end of 2025 and 10 GW by 2030. 

“The residential solar space has been a mainstay,” he said. “I think like everywhere in the country, we do have that doughnut hole in large rooftop commercial and industrial. Not that we don’t have plenty of that, but it hasn’t grown in proportion to the other sectors.” 

Storage

Energy storage is a necessary complement to the intermittent offshore wind, onshore wind and solar generation New York envisions. 

Solar is particularly fickle, with a capacity factor that shrivels to the single digits during the short, cloudy days that mark a New York winter. But wind lulls can be problematic as well. 

State leaders have appropriately ambitious goals for storage, but buildout is off to a slow start. 

Long-duration storage is not available at scale; the present market structure is not favorable for short-term storage; the industry is waiting for the state to finalize a revised roadmap for deployment; and a spate of highly publicized fires has galvanized local resistance to siting. 

William Acker, executive director of the New York Battery and Energy Storage Technology Consortium, said the need and opportunity for intraday energy storage is pressing and the need for longer-duration storage is looming. 

“We’ve got to get going on those things,” he said. “Getting projects built [faces] a number of barriers in New York state, and the roadmap identifies those barriers, creates programs to knock them down and to develop projects. To us this is one of the most important things that needs to happen right now.” 

David Sandbank, NYSERDA’s vice president of distributed energy and transportation, said there is about 12 GW of storage in interconnection queues. NYSERDA itself has contracted 1.3 GW, but less than 300 MW of that is operating or under construction. 

“It’s not a lot. And the 1.3 is about 1.1 right now because of some bulk storage projects canceling,” he said. “I think what you’re going to see in the very near future is a lot of retail 5-MW, four-hour battery storage projects getting built in New York City. There’s about 150 MW right now that are shovel ready.” 

MD Sakib, National Grid’s director of future of electric, repeated that New York now has 250 MW of the 6 GW that the revised roadmap calls for by 2030. 

“Let that sink in,” he said. “There’s a lot that we need to do, and I think there’s a lot of outreach and education that needs to happen.” 

Projects are stalling in the application and review phases, and costs have soared, Sakib said. 

“I think we have the right roadmap in place. … It’s just a matter of getting down to it and making sure we execute those things.” 

Hydrogen

Haiyan Sun, hydrogen and clean fuels program manager at NYSERDA, said hydrogen remains a key part of the state’s decarbonization strategy, even after the U.S. Department of Energy did not award New York and its New England partners the hydrogen hub they were seeking. 

“It will play an instrumental role,” Sun said. “What New York needs to do for hydrogen long term is not going to be affected by whether we have a DOE hub or not. It affected the short-term momentum, certainly, but we respect DOE’s decision. We did not get an answer [on] why we were not selected.” 

Hydrogen will help decarbonize hard-to-electrify sectors, Sun continued. “Hydrogen will also play a critical role in [stability and reliability] of the New York grid while we march along to 70-by-30 and especially when we try to reach zero emissions by 2040.” 

Plug Power Chief Technology Officer Tim Cortes said New York’s support for manufacturing has been an important part of the growth enjoyed by the company, which is headquartered only a few miles north of the capital. 

The proposed federal 45V tax credit rules have given the company pause, however. Much of the hydrogen industry is gnashing its teeth over the draft guidance, Cortes said. 

Jeffrey Goldmeer, director of the global hydrogen value chain for GE Vernova, said technology is not likely to be the sticking point for hydrogen adoption. A greater challenge is likely to be the infrastructure supporting it, he said, recalling a 2021-2022 hydrogen combustion demonstration project at a New York Power Authority peaker plant that was dictated by the availability of green hydrogen, several tanks of which were trucked in each day. 

There is a potential geographic split between where hydrogen is generated and used, Sun said, as well as a seasonal split between the greatest need for green hydrogen and the greatest availability of renewable energy to generate it.

ERCOT, PUC Face Huge Tx Needs in Permian

ERCOT told Texas regulators their initial reliability study of the Permian Basin, the nation’s largest oil production field, indicates “substantial amounts” of local transmission projects are needed to meet the 24 GW of load projected to be added by 2038. 

During the Public Utility Commission’s open meeting April 11, the grid operator’s Kristi Hobbs said it will have to add about 565 circuit miles of new 345-kV lines, eight new 345/138-kV substations with 18 new 345/138-kV transformers and about 344 miles of new 138-kV lines. ERCOT also needs to upgrade about 326 miles of existing 345-kV lines (55718). 

None of that includes “significant” regional upgrades needed to transfer power across the ERCOT system. The grid operator said it will begin identifying import paths into the Permian. 

“There is not a lot of generation within the Permian Basin region to serve all the additional load that is being forecasted,” Hobbs, vice president of system planning and weatherization, told the commissioners. “We will continue looking at revising the plan for the local region as well as coming to you … for what is going to be needed for imports across the state into the region.” 

Hobbs said 58% of the nearly 12 GW of expected non-oil and gas load is composed of crypto mining facilities. Green hydrogen represents 22% of the coming load, with commercial industrials accounting for 12% and data centers 8%. 

“This is just one example of what we’re going to continue to see throughout the rest of the state as we look at reliability plans,” Commissioner Lori Cobos said. 

The PUC last year directed ERCOT to develop a reliability plan for the Permian Basin, a response to legislation passed earlier in 2023 to address the region’s rapidly increasing demand for power. The commission prioritized the plan’s development as it addresses the state’s population and economic growth. 

Saying he senses ERCOT conducts its various modeling studies in silos, Commissioner Jimmy Glotfelty asked Hobbs whether staff could combine some of that analysis. 

“I think this will have an impact on inverter-based resources [in the Permian],” he said. “It will have [an] impact on what we can import to that area and export out of that area, and I just think we need to have a better picture with all of those things modeled together.” 

Hobbs said one of ERCOT’s key goals is evolving the transmission planning process. Staff already are studying 765-kV transmission lines and their integration into the grid. Hobbs promised a report will be delivered to the commission this summer. 

“We’re moving on a fast timeline,” she said. “We recognize the tremendous load growth on the system. We also recognize that the types of resources that are being added to this system are not the traditional resources that we want to plan for. We are looking at ways that we can continue to evolve the process to meet the needs for the fast-growing state.” 

The Permian Basin encompasses 66 counties in southeastern New Mexico and western Texas. It produces nearly 40% of the nation’s oil and roughly 15% of its natural gas, according to the Federal Reserve Bank of Dallas. 

Other Business

In other actions during the open meeting, the PUC approved a 150-MW El Paso Electric (EPE) solar facility (54929) and Xcel Energy subsidiary Southwestern Public Service’s (SPS) rate case (54634). 

EPE’s Texas Solar One is composed of two components: a 50-MW portion the utility plans to dedicate to a voluntary subscription program and a 100-MW portion to serve retail customers. Under an agreement with the city of El Paso, the Office of Public Utility Counsel and Texas Industrial Energy Consumers, EPE will place a capital cost cap on the facility and add a performance guarantee and a commitment to credit its customers with 100% of Texas Solar One’s production tax credits. 

The commission signed off on an unopposed agreement between SPS and various parties that provides for a $65 million increase in the utility’s Texas retail revenue requirement.

FERC Approves Decrease in ISO-NE FRM Offer Cap

FERC has approved a proposal by ISO-NE reducing its Forward Reserve Market (FRM) offer cap from $9,000/MW-month to $7,100/MW-month and delaying the publication of offer data from about four months to a year after each auction (ER24-1245). 

ISO-NE designed the market changes in response to concerns raised by its Internal Market Monitor that recent summer FRM auctions had been “structurally uncompetitive” and that future auctions could be susceptible to market power. 

FRM auctions, held twice annually to procure reserve capacity, will be replaced by ISO-NE’s new day-ahead ancillary services market in March 2025. (See FERC Approves ISO-NE’s Day-Ahead Ancillary Services Initiative.)  

The IMM concluded the previous $9,000 offer cap “substantially overstates a reasonable upper bound on competitive forward reserve supply offers,” while the shorter timeline for offer publication “may provide strategic information to participants” in subsequent auctions.  

In an April 12 order, FERC found that the offer cap reduction provides “sufficient flexibility for resources to participate at their expected costs within the upper end of a competitive offer, while also providing protection from the potential exercise of market power.” 

Then commission also found the delay of offer data publication “balances the need for market transparency with the need to limit the possibility that market information may lead to noncompetitive outcomes.” 

The changes take effect on April 15, 2024, in time for the opening of the first 2024 FRM auction April 17.

Nevada RTO Proceeding Examines EDAM, Markets+ Design

Two competing day-ahead markets from CAISO and SPP are taking different approaches to resource sufficiency and adequacy, according to presenters at a workshop included in an effort that will likely help shape NV Energy’s decision on which market to join. 

The Public Utilities Commission of Nevada (PUCN) hosted the workshop April 10 to discuss regional market designs. 

In CAISO’s Extended Day-Ahead Market (EDAM), balancing areas will undergo a daily resource sufficiency evaluation (RSE) ahead of the market’s 10 a.m. cutoff.  

The balancing areas will work with their load-serving entities and suppliers to ensure sufficient resources and transmission are available to the market, said CAISO Chief Operating Officer Mark Rothleder. The resources must be enough to meet the demand forecast, plus an operating reserve and an imbalance reserve. 

Resources from all participating balancing areas will then be optimized to meet demand across the market and minimize cost, Rothleder said. Entities that don’t pass the RSE will still be able to participate in the market but will be charged a premium. 

In contrast, SPP’s Markets+ day-ahead market will not use a daily resource sufficiency test, said Carrie Simpson, SPP’s director of services development. 

Instead, all load-serving entities in Markets+ must belong to Western Power Pool’s Western Resource Adequacy Program (WRAP), which SPP runs.  

The WRAP includes a forward-showing component that will require participants to demonstrate they have sufficient capacity and 75% of the transmission needed to deliver it seven months before each summer and winter. Those who fail the requirement will face penalties. 

Simpson said obligations coming out of WRAP will inform a day-ahead market participant’s must-offer requirement, “so that we ensure that we have sufficient generation offered into the market.” 

SPP “heard loud and clear” from entities participating in the development of Markets+ about the need for a uniform resource adequacy program, Simpson said. 

“In Markets+, we have a uniform approach so everyone’s on the same playing field,” Simpson said. “To the extent that someone is short today, well, they’re part of the larger program, and we’ll have the capability to have someone else offer for them, and so you get that shared pooling advantage.” 

Rothleder, with CAISO, described EDAM’s resource sufficiency evaluation as “a universal adapter” that can accommodate WRAP, California’s resource adequacy requirements or other RA programs. 

Resources developed under the RA programs can then be used to satisfy resource-sufficiency evaluations, he said. 

“I am not suggesting resource adequacy programs are not important. They are very important,” Rothleder said. “All I’m suggesting is that you don’t have to have a one-size-fits-all resource adequacy program for a day-ahead market optimization to work.” 

The RSE may even be a way to compare different resource adequacy programs, Rothleder suggested. 

“To the extent that the resource adequacy program is performing less than another resource adequacy program, that will be tested by the resource sufficiency evaluation,” he said. 

Competition Heats up

The workshop was part of PUCN’s efforts to find ways to evaluate a utility’s choice of a regional market or RTO. An April 3 workshop focused on studies of day-ahead market benefits. (See Nev. RTO Effort Turns Focus to NV Energy Day-ahead Studies.)  

NV Energy and other utilities across the West are drawing closer to decisions on which day-ahead market to join. Some have already chosen. 

PacifiCorp, the Balancing Authority of Northern California (BANC) and Portland General Electric are among the entities pursuing EDAM membership. CAISO is aiming to launch EDAM in 2026. 

Bonneville Power Administration staff tentatively recommended this month that the agency go with Markets+. (See BPA Staff Recommends Markets+ over EDAM.) 

NV Energy hasn’t revealed publicly its day-ahead market choice. The utility was among more than three dozen entities that participated in developing tariffs and protocols for Markets+, in a process SPP calls Phase 1, but a recent study by The Brattle Group found the utility would realize greater financial benefits from joining EDAM. (See NV Energy to Reap More from EDAM than Markets+, Report Shows.) 

Phase 2, expected to start next year, will begin Markets+ implementation, with a go-live date projected for early 2027. 

Antoine Lucas, SPP’s vice president of markets, said SPP is asking its Phase 1 participants to indicate this quarter whether they’ll be moving forward with Markets+, even if their commitment is nonbinding at this point. 

“I know there is some level of … participants looking to each other to see what they might do,” Lucas said during the workshop. 

When asked what level of participation would be needed to make Markets+ feasible, Lucas said Phase 1 participants decided that 150 TWh of net energy for load annually and two contiguous balancing areas would be enough to move forward. 

WEIS’ Role Clarified

Some entities that join Markets+ might now be participating in CAISO’s real-time Western Energy Imbalance Market (WEIM). In that case, they would leave the WEIM and instead participate in a real-time market that is bundled with the Markets+ day-ahead market. 

The real-time market associated with Markets+ is different from SPP’s Western Energy Imbalance Service (WEIS), a real-time market now in operation, SPP officials noted during the workshop. 

Current WEIS participants, mainly from Wyoming and Colorado, are expected to join Markets+ or SPP’s planned Western RTO expansion, known as RTO West. At that point, SPP expects to discontinue the WEIS, Simpson said.

Counterflow: Offshore Wind Backbone Transmission

The U.S. Department of Energy released a study of offshore wind transmission last month,1 which it said charts a path for a reliable and affordable electric system with HVDC backbone transmission interconnecting offshore wind projects along the East Coast.2 (See DOE Study Adds to Case for Interregional Offshore Grid.)

For starters we need to be clear: In no way does this study establish, or even claim, that offshore wind makes economic sense. Of course it couldn’t, for reasons I’ve given before,3 which are reinforced by all the news of the past year or so.4 Instead, we should be building onshore wind and, where economic, transmitting it from west to east.

What the study actually claims is that hypothetical offshore wind projects of 85 GW along the East Coast, if interconnected among themselves with an offshore transmission “backbone,” would have a positive cost-benefit ratio relative to 85 GW of wind projects separately interconnected to shore with “radial” lines.

In other words, the study claims that if we were to spend $96.3 billion5 on radial transmission lines for 85 GW of offshore wind, it would make sense to spend another $20 billion for offshore north-south HVDC transmission lines to interconnect everything offshore — and, oh yeah, based on year 2050 projections of everything.

Now let’s get to some specific problems with the study.

Legal and Commercial Barriers

Because offshore wind is so expensive, it happens only with large customer (and taxpayer) subsidies through a given state procurement program. For example, in New Jersey’s latest procurement, the developer is receiving $131/MWh in offshore wind renewable energy credits (ORECs) with a price escalator.6 Such procurements effectively or literally require all the wind generation to be delivered to the procuring state.7

Even if a developer were legally able to divert some generation elsewhere, it would have no reason to do so under programs like New Jersey’s where all project revenues are credited back to customers.8 And even if there were no revenue-crediting requirement, a developer isn’t going to divert wind generation elsewhere, such as to New York, except in hours when it could get more than $131/MWh.9 This rarely occurs, and when it does, it is likely that energy prices in New Jersey also would be high.

Energy Price Differences

Assuming the above legal and commercial barriers didn’t exist, let’s examine the study’s principal economic benefit claim: There are huge price differences between different East Coast regions such that there are huge customer savings to be had from moving power up and down the East Coast for injection onshore at different points. “In modeled estimates using the radial topology in 2050, price differences between suitable POIs [points of interconnection] for offshore wind averaged over $100/MWh”;10 for example, “approximately $130/MWh on average between ISO-NE and SERC.”11

This appears to be a mistake. For the year 2050, DOE’s Energy Information Administration projects average generation sector prices of $66.8/MWh in New England and $54.7/MWh in SERC East (South Carolina and the non-PJM portion of North Carolina).12 That is a difference of about $12/MWh, not $130/MWh. The biggest regional price difference is between New England and PJM-East (which contains New Jersey and the Delmarva Peninsula) with a difference of about $16/MWh.13 So there are no $100/MWh average regional price differences that an offshore transmission backbone could arbitrage for the benefit of customers.14 And even if there were, stakeholders subsidizing their state’s wind projects would be none too happy for their wind to be diverted elsewhere in times of high prices.

Oh, by the way, the study’s specific quantifications of customer energy savings are based on a production cost model.15 But, except for the Carolinas and Virginia, customers don’t pay production costs; they pay LMPs.

And the study also implicitly assumes, contrary to actual experience, that resources could and would be dispatched efficiently among regions.16

Resource Adequacy

The study’s second biggest category of claimed benefits is resource adequacy. The study claims $940 million of incremental annual resource adequacy benefit in 2050, relative to a radial transmission design.17 The prime example is that PJM could rely on wind off the Carolinas to be delivered to PJM during peak conditions so the RTO would need less internal generation capacity.18

This also appears to be a mistake. PJM has FERC-approved capacity market rules to ensure resource adequacy that require external generation resources to give operational control to PJM so that external resources are functionally equivalent to internal resources.19 Stakeholders in wind projects off the Carolinas are not going to give PJM operational control.

And if I might pick a nit, the study says Carolina wind would be delivered to “winter-peaking parts of PJM” and specifies Maryland.20 None of the coastal states in PJM are winter peaking, including Maryland.21

Modeling Assumptions

The study has a couple modeling assumptions that seem to put thumbs on the scale.

First, the study assumes “limited [new onshore] interregional transmission.”22 Yes, despite new onshore interregional transmission being all the rage these days, the study assumes nothing is built for the next 26 years.23 If new onshore interregional transmission were built, any price/cost differences would decline as more energy would be deliverable from low-cost areas to high-cost areas, and backbone offshore transmission would be less valuable.

Second, the study assumes “limited-access siting regimes for land-based wind and utility photovoltaics.”24 This assumption is not explained, but it seems safe to observe that if one assumes limited onshore renewable resources, offshore resources will look more attractive. This assumption is belied by the hundreds of gigawatts in proposed onshore renewable resources.25

Incremental Annual Cost

In developing its benefit-cost ratios, the study doesn’t provide detail for its capital costs.26 But the study does drop a footnote for its assumptions on converting capital costs to annual costs,27 and we can back into the annual costs. So, for example, comparing the radial scenario with the backbone scenario, we know that if claimed incremental “economic value” is $3,940 million28 and if claimed incremental “net annual value” is $2,470 million,29 then the implied annual cost is $1,470 million.

If the incremental capital cost is $20 billion and the annual cost is $1,470 million, then that means the assumed annualized cost percentage is 7.35%. But that is not realistic. For example, the annual carrying charge rate for transmission owners in PJM is about 11.8%,30 and annual O&M expense is on top of that.

Engineering Feasibility

I am no engineer, but there is an Argonne National Laboratory study that says HVDC systems can’t have more than five substations: “The number of substations within a modern multi-terminal HVDC transmission system can be no larger than six to eight, and large differences in their capacities are not allowed. The larger the number of substations, the smaller may be the differences in their capacities. Thus, it is practically impossible to construct an HVDC transmission system with more than five substations.”31 And National Grid describes major issues with multi-terminal HDVC systems.32

The DOE backbone design has 26 substations.33 How does that reconcile with the Argonne and National Grid analyses? I have no idea, but these are things the study should have addressed.

And there’s another potential engineering issue called the “most severe single contingency,” which involves the sudden loss of a single source of electric generation, generally around 1,200 MW. It is unexplained how aggregated offshore wind generation delivered onshore in excess of the MSSC would not trigger reliability and reserve issues.

What Else Could Possibly Go Wrong?

Spend $20 billion here, $20 billion there, and pretty soon we’re talking real money. And those who might rationalize spending “only money” on offshore wind backbone transmission should consider how much a focus on standard design among offshore transmission projects, in order to enable backbone transmission, might delay or even frustrate such projects.

In Conclusion

DOE should rethink this.

NY Energy Officials Optimistic About Transition Despite Slow Progress

ALBANY, N.Y. — Regulators, state officials and industry were upbeat about New York’s efforts to decarbonize its grid at the annual New York Energy Summit, staged by Infocast on April 8-10, even as they repeatedly noted that much work needs to be done — namely, building more renewable resources and transmission lines. 

Like many states, New York has committed to expanding generation and transmission capacity while simultaneously reducing emissions. For professionals in the field — whether their motivation is profit, the planet or some combination of factors — the Empire State is a target-rich environment. But the targets are not easy to meet. 

Once again, state leaders have missed their March 31 budget deadline. As of press time, the state still had no 2024-2025 spending plan and therefore no clear indication which policy initiatives will be baked into it, including the proposal by Gov. Kathy Hochul (D) to speed up transmission siting. (See NY Gov. Proposes Streamlined Transmission Review, Permitting.)

John O’Leary, Hochul’s deputy secretary for energy and environment, delivered a keynote overview of the state’s energy transition but could not give summit attendees any insight on proposals that would affect their business strategies. 

“In the parlance of New York state budget making, you might say today is not in fact April 8 but instead March 39,” he said. “We’re certainly into extra innings.” 

Vennela Yadhati, vice president of renewable project development for the New York Power Authority, said Hochul’s transmission streamlining proposal — the Renewable Action Through Project Interconnection and Deployment (RAPID) Act — is critical to the state meeting its statutory targets for decarbonization. The first milepost, 70% renewable energy by 2030, is just six years away, and New York is still far short. 

“I’m sure that you all agree with me that we need this legislation enacted if New York is going to meet its goals,” Yadhati said. 

Faster and Smoother

The RAPID Act would place environmental review and permitting of transmission projects under the purview of the state Office of Renewable Energy Siting (ORES), which in its four years of existence has greatly accelerated the application process for large-scale renewables.

The ORES pre-application process can be lengthy, but it yields an application that is complete and can withstand the close review to which it will be subjected. ORES so far has permitted 15 projects totaling 2.3 GW, the majority of them in less than eight months, Executive Director Houtan Moaveni said. 

“It takes longer to get a heated pool permit in Westchester County than a 500-MW solar project in New York state,” he added. 

An ORES permit is an important milestone, but it is just one piece of a large puzzle. With the impending retirement of more fossil fuel-fired plants, New York needs more generation and transmission capacity immediately, Moaveni said. 

“I’m preaching to the choir,” he told the room. “We really, really have to accelerate the pace of development in New York state.” 

NYISO President Rich Dewey | © RTO Insider LLC

The choir had some prominent members, including the federal and state energy regulatory agency heads and NYISO CEO Rich Dewey. 

FERC Chair Willie Phillips waved the flag for the commission’s own efforts. “We took the best parts of interconnection reform from every part of the country, and no one part of the country is doing … everything that we’re requiring in Order No. 2023,” he said. 

Dewey said NYISO had a head start on Order 2023 compliance and spoke proudly about the ISO’s improvement in managing its queue. 

“When Order 2023 came out, we welcomed that, because we had already been at it for about a year in terms of trying to get our processes fine-tuned,” he said. “We’re happy to report that our SRIS [system reliability impact study] process last year took an average of 132 days. The average of the three years preceding that was 420 days.” 

When asked what differentiated NYISO’s transmission planning from those of other grid operators, Dewey touted the ISO’s “very, very robust” process for identifying reliability needs and New York’s Public Policy Transmission Needs process, in which the state solicits projects and the ISO evaluates and selects the best solution. 

“In the middle of that, we have our economic planning process, and I think that’s where our gaps have been,” he continued. NYISO’s System & Resource Outlook lays out multiple scenarios that might unfold over the next two decades and identifies pathways through them, he said.

It is not an action plan, however. “We don’t have a means to act on that today; it’s more informational,” Dewey said. (See NYISO 20-Year Forecast Highlights Generation, Tx Hurdles to Climate Goals.) 

But the present practice of building transmission one interconnection at a time as needed is neither efficient nor effective, Dewey said. Measures such as proactive infrastructure construction and New York’s new Coordinated Grid Planning Process (CGPP) will address this, he said. (See NY Creates Coordinated Grid Planning Process.) 

Zeryai Hagos, of the state Department of Public Service, explained that the CGPP will attempt to integrate the distribution, local transmission and bulk transmission planning processes on a repeating cycle to identify upcoming infrastructure needs. 

New York Public Service Commission Chair Rory Christian spoke of the imperative to think beyond interconnections and conductors when developing the grid of the 21st century.

If demand-side management isn’t used, that grid must be overbuilt or overused to handle peak load, with a proportionally greater impact on equipment, the environment and ratepayers. 

“Addressing the rise in peak load … is central to the commission’s ability to ensure affordable, safe, secure and reliable access to utility services and just and reasonable rates,” he said. “Our ability to control the peak gives us flexibility that we would otherwise not have. This is the challenge the grid of the 21st century is being designed to meet.” 

NYISO’s Yachi Lin said the ISO’s upcoming report on capacity and transmission constraints will predict a need for 100 to 130 GW of installed capacity in New York in 20 years. This compares with approximately 37 GW of existing generating capability identified by the NYISO Gold Book in April 2023. 

Glenn Haake, vice president of regulatory affairs at Invenergy, applauded the PSC for creating the CGPP and for greenlighting billions of dollars’ worth of transmission projects after decades of minimal investment.

John Howard, who recently completed a term as a PSC commissioner, said transmission investments have long been trimmed when utility regulators review rate cases. As a result, he said, some conductors in New York are as old as he is. 

“It’s certainly something that commissions knew was dropping off the table,” Howard said. 

Christian and many others have spoken of this problem as a way of easing customers’ sticker shock over the costs of the energy transition: The nation’s grid would need extensive and expensive investments even without an energy transition. 

Energy transition challenges notwithstanding, the grid does function well, NYISO COO Emilie Nelson said. 

“One of the things that we do have in New York is we’ve invested in a lot of capability through the years. Our interconnected grid — our ability to move power across each and every border of New York to the neighboring areas — serves us well.”

DOE Releases New Efficiency Standards for Light Bulbs

The Department of Energy has released finalized energy efficiency standards for “general service lamps, which include the most common types of commercial and residential light bulbs.” 

The congressionally mandated standards go into effect in July 2028 for newly produced bulbs and are expected to save $1.6 billion annually on energy costs, cut waste and avoid carbon emissions. Over 30 years, DOE projects the standards will save more than $27 billion on utility bills and cut 70 million metric tons of carbon emissions. 

“Making common household appliances more efficient is one of the most effective ways to slash energy costs and cut harmful carbon emissions,” Energy Secretary Jennifer Granholm said in a statement April 12.  

DOE continues to implement the law on efficiency standards, and so far under the Biden administration, it has promulgated standards that cumulatively save $1 trillion in energy costs over 30 years and could save the average family $100 a year through lower utility bills. The standards cumulatively will cut 2.5 billion metric tons of greenhouse gas emissions, which is equivalent to 22 coal plants, over 30 years. 

The standards increase the efficiency level from 45 lumens per watt to more than 120 lumens per watt for the most common light bulbs, which DOE said is in line with industry trends shifting toward more efficient and longer-lasting LED bulbs. The new standards will save 4 quadrillion BTUs, or 17%. 

The department already has implemented efficiency standards that cannot be met by old, inefficient incandescent bulbs and were specifically directed by the Energy Independence and Security Act of 2007. The standards issued April 12 are part of a congressional requirement that DOE regularly review efficiency standards to ensure consumers benefit from technological improvements. 

The new standards can be met with a broad variety of LED bulbs, but not compact fluorescent bulbs (CFLs), which the market is transitioning away from. LEDs last longer, use less energy and do not contain mercury like CFLs. 

The American Council for an Energy Efficient Economy (ACEEE) welcomed the standard and noted that most light bulbs on the market are LED. A common bulb equivalent to old 60-watt models will use no more than 6.5 watts under the new standards once they go into effect. Many LED models today use 8 to 10 watts, while the harder-to-find compact fluorescents use about 13 watts, ACEEE said. 

“LED technology has gotten even better in recent years, and these standards will ensure that all products on the market catch up with the latest efficiency advances,” said Andrew deLaski, executive director of ACEEE’s Appliance Standards Awareness Project.

MISO Offers 2-stage Plan for DER Aggregations in Markets

MISO hopes it can use a two-step approach to Order 2222 compliance, first using a demand response category in 2026, with full market participation of aggregations of distributed resources still on the RTO’s original 2030 timeline that FERC refused last year.  

MISO revealed at an April 11 DER Task Force teleconference the near-final revised Order 2222 compliance plan it intends to file with FERC. 

The RTO has divided its plan to allow DER aggregations in its markets into two parts. First, it plans to use an existing demand response resource participation category to get aggregations of distributed resources participating sooner, albeit on a limited basis. MISO said it can begin registering DER aggregations under its demand response resource participation model by Sept. 1, 2026, and begin participation by June 1, 2027.  

For demand response participation, DER aggregations must be at least 1 MW and MISO would commit them for either energy or contingency reserves. 

A few years later, MISO would roll out its comprehensive Distributed Energy Aggregated Resource model at the beginning of 2030. It plans to register aggregations beginning June 1, 2029, allow DER aggregations to participate in its energy and ancillary services by Jan. 1, 2030, and finally open capacity market participation to aggregations by June 1, 2030.  

MISO’s Marc Keyser said though stakeholders might think the deadline remains unchanged from the one FERC rejected last year, this proposal has the RTO working on the necessary changes to its settlements system this year to incorporate aggregations. (See FERC: MISO’s 2030 Finish Date on Order 2222 Compliance not Soon Enough; Stakeholders Ask MISO to Share New Order 2222 Go-live Date ASAP.)  

However, MISO would not adopt a wide-ranging, multinodal approach for aggregation. Aggregations would be limited to multiple nodes within a single load-balancing authority and a single load-serving entity, as they are today under its demand response resource model.  

“Adding more locations adds complexity,” MISO’s Kim Sperry said. She said the complexity is not limited to the RTO, but seeps into aggregators and distribution utilities’ processes.  

Sperry said MISO keeping its DER aggregation locational limits in line with its demand response resource rules allows it to not take on “too much too fast.” 

“We’re not trying to bring something brand new to the stakeholder community,” she said.  

Some stakeholders questioned why MISO needs three years of prep work to employ an existing resource model for DER aggregations.  

MISO DER Program Manager Paul Kasper said MISO needs time to complete a new, “foundational” settlement system tool to accept DER aggregations. 

Other stakeholders said the 1-MW size minimum seemed restrictive and pointed out that some states in MISO’s footprint prohibit aggregators from providing demand response and effectively would be shut out of the markets until 2030. 

MISO no longer accepts stakeholders’ written opinions on its revised Order 2222 implementation plan and has until May 10 to file its new compliance. It will present its final compliance plan to stakeholders at the April 18 Market Subcommittee.

Still More Work for ISO-NE on Order 2222 Compliance

FERC on April 11 accepted ISO-NE’s fifth Order 2222 compliance filing while requiring the RTO to make additional changes detailing deadlines for distributed energy resource aggregators to submit metering data (ER22-983-007). 

Order 2222 aims to enable DER aggregations to participate in regional wholesale markets. FERC wrote that ISO-NE’s proposal met the requirements to make DER aggregators responsible for providing required metering information to the RTO, and to create standards for aggregators that work with host utilities to share these data. 

However, the commission concluded that ISO-NE did not meet the requirement to change its tariff to specify data submission responsibilities and deadlines, disagreeing with its contention that these instead should be included in the RTO’s manuals. 

“ISO-NE fails to address adequately the commission’s finding in the Nov. 2 order [the RTO’s third compliance filing] that the meter data submission deadline is a key component of metering practices for DER aggregators that should be included in the basic description of metering practices in the tariff,” FERC wrote.

ISO-NE in February 2022 submitted its first compliance filing to Order 2222, issued in November 2021. FERC directed additional changes, which the RTO submitted in three batches last year. The commission accepted the second and fourth filings without requiring any changes, but it ordered another round in response to the third. (See FERC Accepts ISO-NE Order 2222 Compliance Filing.) 

ISO-NE has 60 days to submit its sixth filing.
