Analysis Group: No Changes to NYISO CONE Method Needed

The Analysis Group told NYISO stakeholders Aug. 22 that it did not recommend any major changes to the annual process for updating the ISO’s gross cost of new entry for generators, saying it did not find any other, more accurate source of data on component costs.

NYISO increases its CONE every year between its quadrennial demand curve resets (DCRs) to account for inflation. It uses data from inflation indices for four major components of engineering, procurement and construction costs: generating equipment, labor, materials and other miscellaneous costs.

Stakeholders have raised concerns that the Analysis Group’s recommendation of a two-hour lithium ion battery storage system as the peaker plant for the 2025-29 DCR — a change from GE Vernova’s 7HA.02 gas turbine — leads to higher CONE values.

But the consultancy said the increase is attributed to factors that are not taken into account in the annual update — and they should not be.

“In our view, annual updates are not designed to replicate a full demand curve reset,” Daniel Stuart, a manager and public policy expert for Analysis Group, told the Installed Capacity Working Group. “They just can’t consider policy changes in market factors, [such as] federal policy that provides a new tax credit for battery storage technology that will never be picked up on an inflation index.”

The consultancy did, however, change an index it had recommended to estimate the generating equipment component for battery storage systems to one that that excludes lead acid batteries.

“That seems like a helpful improvement to exclude a kind of battery that is quite different from lithium ion batteries,” said Stuart. “But beyond that, we have not found any other indices that more accurately reflect the changes and the four cost components defined in the tariff.”

Howard Fromer, director of regulatory affairs for Bayonne Energy Center, expressed concern that utility-scale batteries would not be accurately represented by the new index because they represent a small minority of the batteries included.

“It’s going to get watered down by including a lot of stuff [that] aren’t even subject to tariffs,” Fromer said. “We’re going to miss a huge potential component going forward.”

Stuart asked what other index should be used. Fromer suggested adjusting the index; Doreen Saia, chair of the Albany office of energy and natural resources practice for Greenberg Traurig, said the risk factor could be adjusted.

“Throwing up our hands and saying, ‘We just can’t get there,’ doesn’t ignore the fact that an investor will just throw up his hands,” Saia said.

Amanda De Vito Trinsey, a lawyer with Couch White representing New York City and Multiple Intervenors (MI) — a group of large industrial, commercial and institutional energy consumers — stepped in.

“I hear what everyone’s saying, and I understand the concern,” Trinsey said. “We don’t know what will happen, and so I think we’re doing the best with what we have in place. The city and MI support the process that you have here, and we don’t see any reason to depart. … What we have now captures that risk adequately.”

NERC Following ‘Very Ambitious Timeline’ for IBR Conference

Plans are advancing rapidly for a technical conference to resolve an impasse on a proposed reliability standard, NERC staff told members of the organization’s Standards Committee during its monthly conference call this week.

The technical conference, scheduled for Sept. 4-5 at a still-to-be-announced location near NERC’s Washington, D.C., office, is intended to address FERC’s directive in 2023 — part of Order 901 — to submit reliability standards by Nov. 4 addressing IBR performance requirements, disturbance monitoring data-sharing and post-event performance validation. 

NERC has produced five draft standards relating to FERC’s order, four of which have met the two-thirds weighted stakeholder approval needed for submission to the commission. However, the last standard, PRC-029-1 (Frequency and voltage ride-through requirements for inverter-based resources), failed to receive approval in its most recent formal ballot round that ended Aug. 12. 

The failure of PRC-029-1 to win industry approval and the impending FERC deadline prompted NERC’s Board of Trustees to take unprecedented action to break the impasse. Invoking its authority under Section 321 of NERC’s Rules of Procedure, the board directed the Standards Committee to convene a technical conference to gather input from industry, which it will use to revise the proposed standard. (See “Board Invokes Standards Authority to Meet IBR Deadline,” NERC Board of Trustees/MRC Briefs: Aug. 15, 2024.) 

NERC will submit the revised standard for stakeholder ballot; if it receives at least a two-thirds weighted stakeholder approval, it will be considered approved. 

NERC Manager of Standards Development Jamie Calderon acknowledged the board’s directive established “a very ambitious timeline” for the entire process, which must be finished by the end of September. 

“We have 45 days to plan the conference, implement the conference, take the results of the conference, revise the standard … ballot the standard, and close that ballot. All within a 45-day window,” Calderon said. “It’s absolutely going to be crucial that we are working in concert with the SC throughout.” 

Calderon said the planning has been especially challenging because until Aug. 12, NERC did not know which of the proposed standards, if any, would fail the ballot and what the board’s decision would be for those that did. ERO staff knew there was a possibility they would have to organize a technical conference on short notice, so they “have been working diligently [with SC leadership] to make sure [they] can hit the ground running.” 

While NERC announced following its board meeting the technical conference would take place in its D.C. office, Calderon said interest has grown so rapidly the ERO no longer believes its office will have sufficient space for all attendees. Even capacity at the backup offsite location soon may be reached, she said. To allow as many interested parties to participate as possible, NERC has implemented a virtual attendance option for the conference as well.  

The board has scheduled a special conference call Oct. 9 to discuss the stakeholder vote on the revised standard. A vote of less than two-thirds will not necessarily mean the standard is rejected. According to Section 321, the board has the option of accepting the standard if it receives at least 60% weighted approval. 

Soo Jin Kim, NERC’s vice president of engineering and standards, reminded attendees the technical conference is just one option for getting the IBR ride-through standard over the finish line. Section 321 also allows the board to direct the SC or NERC management to develop a draft standard without stakeholder input and submit it to FERC directly after posting it for a 45-day comment period.

The board previously threatened to invoke this authority in 2023 to pass NERC’s draft cold weather standard, but the measure ultimately was unnecessary after industry approved EOP-012-2 in its final formal comment and ballot period. (See Industry Approves New Cold Weather Standard in Final Vote.) 

“If this fails to get to 60%, we would have to go back to the board to adopt that procedure with a very, very compressed time frame, because we would still need to meet the Nov. 4 deadline,” Kim said. “That does not require a technical conference, [and] it does not require another ballot. So I just want to remind everyone that that path is a little bit more aggressive with regards to drafting and language.”

CAISO Kicks Off New Initiative to Streamline Bilateral Trading

A new initiative to streamline and expand bilateral trading in the Western Energy Imbalance Market (WEIM) and Extended Day-Ahead Market (EDAM) was launched Aug. 20, marking another important step toward EDAM implementation.

The initiative centers on inter-scheduling coordinator (inter-SC) trades, an optional market feature facilitating settlement of bilateral contracts between scheduling coordinators (SCs).

“As we’ve been going through implementation activities, we’ve seen some requests where there may be potential value in inter-SC trade functionality,” said Milos Bosanac, regional markets section manager at CAISO. “The lift to implement this functionality is not extensive, and it’s something that could be included, if approved, within the broader implementation activity of the EDAM effort for May of 2026.”

According to the straw proposal, SCs in the ISO market can submit an inter-SC trade, which is a settlement service for parties of bilateral contracts to offset ISO settlement charges against bilateral contractual payment responsibilities. Inter-SC trades don’t have an impact on market optimization, schedules or dispatch, and currently are supported in the ISO balancing area, but not in the wider WEIM or future EDAM footprint.

There are three types of inter-SC trades involving energy, ancillary services and the integrated forward market (IFM) load uplift obligation. Trades of energy can facilitate settlement of bilateral power purchases or trades of energy between SCs in the day-ahead or real-time markets and can be made at physical generator locations (PNodes) or at aggregate pricing nodes (APNs).

Ancillary services trades can facilitate bilateral arrangements of regulation-up, regulation-down, spinning and non-spinning reserve ancillary services obligations. These are financial-only trades that are not at defined locations in the real-time market. In the WEIM and EDAM markets, ancillary services are not optimized or settled through the market, and therefore, the ISO isn’t proposing to extend this type of trade to the broader markets.

IFM load uplift obligation trades can facilitate transfer of bid cost recovery obligations between parties based on bilateral contract arrangements. Like ancillary service trades, they do not occur at defined locations and operate only in the real-time market, and aren’t being considered for extension, either.

“We’re also not proposing, at this stage, to extend this type of inter-SC trade to EIM and EDAM areas for a couple of different reasons, primarily that this is really a feature of participation in the day-ahead market so it wouldn’t necessarily be applicable in the EIM,” Bosanac said. “The current structure of settlement of the IFM load uplift obligation in the EDAM is with the balancing area, not necessarily with the discrete loads within that balancing area. So, there might not be much value to this type of inter-SC trade.”

For trades at physical locations, settlements occur based on the locational marginal price at the location, and there is no limit to the number of trades that can occur. But at APNs, only one trade can occur per scheduling coordinator each hour. Some stakeholders took issue with the limit on trades.

“This will not meet WAPA’s requirements,” said Tong Wu, representing the Western Area Power Administration. “We need to be able to have multiple trades because we have multiple customers … so although from WAPA’s side there’s only one SC, on the customer side, there will be multiple SCs that we need to trade with.”

Dan Williams, principal advisor of Western markets at The Energy Authority, shared Wu’s concern.

“WAPA has really defined the need statement very well within its resource portfolio for why this needs to exist and how it can be used,” Williams said. “There’s probably still a little more work.”

The initiative received overall support and is expected to be presented to the ISO Board of Governors and Western Energy Markets Governing Body in early November.

DOE Wind Power Reports Show Mixed Results in 2023

The 2024 editions of the U.S. Department of Energy’s wind energy market reports show growth amid challenges. 

Utility-scale onshore wind capacity increased by 6.5 GW in 2023. While that represented a $10.8 billion capital investment, it was the third consecutive annual decline, and the smallest capacity addition since 2014. 

The emerging U.S. offshore wind industry ran into serious problems in 2023, and by May 2024, there still was only 174 MW operational in U.S. waters. But three projects totaling 4,097 MW were under construction, and four other projects totaling 3,378 MW had been permitted. 

Distributed wind capacity nationwide reached 1,110 MW with the addition of 1,999 new turbines in 16 states in 2023. This was more turbines than were added in 2022 or 2021, but the cost and the capacity of those additions was greater than in 2023. 

The difference in 2022 and 2023 average wind speeds is shown across the 48 contiguous states. | Pacific Northwest National Laboratory

DOE’s Wind Energy Technologies Office funded the reports, which were compiled by three DOE national laboratories. 

The office said in a news release that the policies of the Biden administration and funding from the Inflation Reduction Act have accelerated the wind energy sector to the point that it accounted for more than 10% of electricity generated and 12% of capacity added in the United States in 2023. 

It said the U.S. project pipeline is 53% larger than a year ago and projected that annual capacity additions would exceed 15 GW by 2026 and be nearly 20 GW by 2030. 

Onshore Wind

The Land-Based Wind Market Report was prepared by Lawrence Berkeley National Laboratory. 

Highlights include:  

    • Installed capacity surpassed 150 GW in 42 states, with Texas leading in nameplate capacity (41,594 MW) and Iowa leading in percentage of in-state electricity generation (59.2%). 
    • General Electric built the majority of wind turbines installed in the U.S. in 2023 — 58%. Vestas was a distant second at 30%. Nordex and Siemens-Gamesa Renewable Energy accounted for 9 and 4%, respectively. 
    • The U.S. wind industry continues to rely on imports, although the IRA has created renewed optimism about domestic supply chain expansion; annual U.S. production capacity at the end of 2023 stood at 15 GW for nacelle assembly, 12 GW for tower manufacturing and 4 GW for blade manufacturing. 
    • Independent power producers own over 90% of the new wind capacity installed in 2023. 
    • Direct retail purchases of wind power, including corporate offtakers, led the market for new wind energy capacity for a second year in a row, buying electricity from at least 48% of the new facilities; electric utilities were a distant second at 29%. 

Offshore Wind

The Offshore Wind Market Report was prepared by the National Renewable Energy Laboratory (NREL). 

Highlights include: 

    • Using the broadest definition, including the maximum potential capacity of lease areas that are newly designated but not yet sold, the U.S. offshore wind pipeline grew 53% to 80,523 MW as of the end of May. 
    • Just over 25,000 MW of that pipeline calls for floating wind turbines, which still are in the development stage and are not expected to be installed in U.S. waters at commercial scale anytime soon. 
    • Estimated investment in the U.S. offshore wind supply chain has reached $10 billion since President Biden took office; NREL has estimated the need to be at least $22 billion. 
    • State-level policies continue to drive offshore wind development; as of May 31, mandates in eight states total 45,703 MW and non-binding planning targets in five states total 69,427 MW. 
    • Fifteen contracts to purchase 12,378 MW from offshore wind farms have been signed. 
    • The report tallied 68,258 MW installed capacity worldwide as of December 2023, less than 100 MW of it in the United States. 

Distributed Wind

The Distributed Wind Market Report was prepared by the Pacific Northwest National Laboratory.

Highlights include: 

    • Ohio, Illinois and Alaska accounted for 78% of the distributed wind capacity added in 2023. 
    • Large turbines (larger than 1 MW) accounted for 69.5% of capacity added; midsize turbines (101 kW to 1 MW) accounted for 8.6%; small turbines accounted for 21.9%. 
    • The major distributed projects in 2023 were a 4.5-MW facility for a lime manufacturing plant in Ohio, a 2.8-MW facility to support an EV maker’s plant in Illinois and a 0.9-MW facility to serve communities in Alaska. 
    • Only 11% of distributed wind installed in 2023 feeds into the grid for local use, while 89% was installed to supply an on-site use; this was an aberration caused by two particularly large projects at industrial sites. 
    • Significant activity and investment in the small wind market in 2023 suggests development might increase in coming years.

Exec Details MISO’s Tight Spot Between Load Growth, Retirements, Unwieldy Queue

INDIANAPOLIS — Senior Vice President Todd Hillman encapsulated MISO’s current pressure cooker environment of escalating data center demand, a precarious reliability situation and an overwhelmingly large interconnection queue at Infocast’s inaugural Midcontinent Clean Energy Summit Aug. 20.

Hillman said the days of 0.6 to 1% “anemic” load growth MISO-wide are in the rearview. He said MISO is bracing for 10% load growth in the next few years, driven by 14 to 16 GW of new facility demand.

But he added a caveat that MISO has poor visibility into the magnitude and entrances of large loads. Complicating matters, MISO is scraping its reserves as generation retirements continue.

“In the Midwest, we are at our reserve margins,” Hillman said. “We’ve already been driving to this reserve margin without any load growth.”

MISO expects 80-plus GW of retirements in its dispatchable fleet by 2042, Hillman said.

“We’re all waiting for that next thing: ‘Is it small nuclear reactors, is it long-duration storage, is it, is it, is it?’ My question is when will these technologies become commercially viable? Because we need them now,” he said.

For its part, MISO is trying to craft markets that place reliability front and center, Hillman said, invoking MISO’s proposed availability-based capacity accreditation for all resources, efforts to beef up scarcity pricing and exploring a possible new resource adequacy standard to replace the loss of load expectation.

Hillman said the MISO community should take notice of PJM’s capacity auction, where Dominion Energy’s entrance caused its zonal price to skyrocket to more than $440/MW-day. He said the unofficial data center capital of Arlington, Va., contained in the zone provides a cautionary tale for MISO. He said PJM and MISO, which can rely on one another in times of need, cannot count on the other’s imports when both regions are maxed out before emergency conditions descend.

“You can’t have two drunks leaning on each other. One of them is going to fall down. Now I’m not saying MISO is the drunk. I’m not saying that,” Hillman joked to audience laughter.

Hillman said the typical data center can be built in a matter of months. Generation, on the other hand, takes about six years to build, factoring in queue wait times and construction obstacles.

He said the situation is becoming desperate enough that Holtec International will attempt a restart of Palisades’ 800 MW reactor in Michigan after three years of retirement “to the low, low, low introductory price of $2.5 billion.”

Hillman also touched on the double-edged sword nature of MISO’s very active interconnection queue, which potentially could grow to 350 GW if MISO certifies all 123 GW of its 2022 queue submittals.

“The good news is that we have a very robust queue. The bad news is that we have a very robust queue,” Hillman said.

He said MISO’s active queue is so large engineers deem it “technically infeasible” to study potential interconnections.

Hillman reflected on how far MISO has come in two decades. He pointed out that the conference’s location, the Mariott Indianapolis North, was the site of MISO’s first annual meeting in 2005.

Back then, MISO was in the thick of what would become known as “Peakerfest,” Hillman said, where control room operators would over-commit peaking resources out of an abundance of caution. He also said MISO’s then approximately 5 GW wind fleet now stands at 35 GW.

“We’ve basically had three generation renaissances in the last 50 years,” Hillman said of the energy industry. He noted that from about 1969 to 1986 the nation built about 200 GW of coal power, which was followed by approximately 200 GW of new natural gas generation in the 1990s and the early 2000s surge in wind farms.

“Now we’re in the fourth renaissance, and that’s a load renaissance,” Hilman said. He called for a “higher level of debate” on the clean energy transition.

“We have always seen our industry come through,” he said. “It’s going to be quite the ride. It’s going to be quite the adventure.”

CAISO Adjusts Timeline for Storage Bid Cost Recovery Initiative

Responding to significant stakeholder pushback, CAISO has extended the timeline of its Storage Bid Cost Recovery and Default Energy Bids Enhancements initiative to allow more discussion of alternative solutions to refine BCR provisions for storage resources. (See CAISO Proposal Seeks to Refine Storage Bid Cost Recovery.) 

CAISO staff discussed the changes in an Aug. 19 meeting originally intended to review the revised straw proposal slated to be released Aug. 14. But after stakeholders consistently asked for a more holistic initiative, the meeting was spent considering alternative proposals to the first one presented by the ISO.  

“This is a change that we think will support stakeholders to collaborate with us to develop those ideas so that we can continue comparing them to other proposals and determine what is the best path forward given the challenges that we’re trying to solve,” said Sergio Dueñas Melendez, storage sector manager at CAISO. “I want to note that this revised schedule does not change the importance and the sense of urgency that we have in addressing this issue.”  

In 2022, the ISO identified that bid cost recovery (BCR) provisions for energy storage didn’t align with the intent of BCR, resulting in unusually high payments to storage resources. (See CAISO Kicks Off Storage Bid Cost Recovery Stakeholder Initiative.)  

The problem materialized because CAISO’s BCR construct doesn’t adequately consider state of charge (SOC), Dueñas Melendez said, which is necessary for an energy storage resource to support its awards and schedules. It led to two main concerns: that storage assets are not exposed to real-time prices for deviating from day-ahead schedules and that they may have an incentive to bid strategically to maximize the combined BCR and market payments.  

In response, the ISO presented a proposed solution that would redefine dispatch that is unavailable due to SOC constraints in the binding interval as “non-optimal energy,” which would be ineligible for BCR. If a storage resource’s SOC at the start of the binding interval was equal to its minimum or maximum value, the market would rerate or derate the Pmax or PMin to zero in order to capture that the asset is completely full or empty, the proposal says.  

Alternative Proposals

Some stakeholders supported the proposal, including the California Public Utilities Commission’s Public Advocates Office, which described it as “a measured and sufficiently well-targeted approach to ensure that storage resources are not incentivized to deviate from day-ahead schedules to achieve excess BCR payments,” Dueñas Melendez’s presentation said.

Others, such as the California Energy Storage Alliance (CESA), suggested implementing an alternative solution in the interim that would address concerns related to strategic bidding. CESA proposed modifying the formula used to calculate BCR from real-time dispatch minus day-ahead schedule to day-ahead locational marginal price (LMP) minus real-time LMP. This calculation would eliminate the impact of a resource’s bid on BCR payments, according to CESA.  

“Stakeholders have argued for this solution for a couple of reasons: first, because it would eliminate the impact of that resource’s bid on BCR payments, so that way it’s no longer something that they can strategically use,” Dueñas Melendez said. He added that other stakeholders favored the solution because the software they use for automatic bidding uses -$150/MWh bids in the hours representing their day-ahead schedules to firm up those bids or schedules.  

While stakeholders supporting the proposal acknowledged the solution wouldn’t address the concern that storage assets are not exposed to real-time prices for deviating from day-ahead schedules, they argued it would allow for more time to develop a more “holistic” solution.  

Dueñas Melendez highlighted other potential drawbacks of the proposal, including that it would not eliminate buy- and sell-back BCR and that it would pay BCR to resources that are not available in real time. The ISO also questioned how the proposal would be implemented for storage assets in the Western Energy Imbalance Market (WEIM) outside CAISO’s footprint, considering that there is no day-ahead LMP for WEIM storage resources.  

CAISO further questioned CESA’s proposal, stating that the modified calculation could lead to revenue credit in intervals where the resource wasn’t dispatched due to a high offer, as well as unwarranted BCR when the day-ahead LMP is greater than the real-time LMP.  

Don Tretheway, director of markets and regulatory policy at GDS Associates and representing CESA, responded: “The intent of what CESA put out there was really to address instances where there was inflated BCR, so putting out an example that says the CESA proposal results in higher BCR payments … we would never have put that out as an approach, and we did recognize that there would be the need for some additional logic.” 

The intent of the approach, he said, was to show that not using real-time bid prices could help “unwind the inflated BCR payments,” giving the ISO more time to “come up with a holistic solution about what BCR should mean for storage” and what market design enhancements CAISO should pursue.  

CAISO’s Department of Market Monitoring disagreed with the suggestion to develop an interim solution, saying that addressing all issues in track 1 is a better approach than implementing an interim change and then tackling bidding incentive issues — which DMM believes to be the core issue — in a later process.  

The revised straw proposal is now scheduled for release Sept. 3, with the final proposal expected Sept. 30, a month later than the initial timeline. The joint ISO Board of Governors and Western Energy Markets Governing Body will vote on the proposal Nov. 7 instead of Sept. 26.

SDT Recommendations Spark Debate at Standards Committee

Members of NERC’s Standards Committee again debated qualifications for standard drafting team participation at their monthly conference call Aug. 21, with the discussion extending the meeting more than a half-hour over its planned end time.

The committee was considering two proposals submitted by NERC staff to approve members of new standard drafting teams (SDT), along with a proposal to add supplemental members to an already existing team. The new teams were for Project 2024-01 (Rules of Procedure definitions alignment — generator owner and generator operator) and Project 2024-03 (Revisions to EOP-012-2), while the existing team to be augmented was for Project 2022-02 (Uniform modeling framework for inverter-based resources).

Project 2022-02 came first on the agenda. NERC Manager of Standards Development Jamie Calderon explained that NERC recently assigned the project a new standard authorization request (SAR) in response to FERC Order 901, which requires the ERO to submit standards concerning data sharing and model validation for inverter-based resources (IBRs) by November 2025. (See NERC Standards Committee Moves Forward on IBR Projects.)

Because of the scope of the new SAR, Calderon said, the existing SDT members wished to bring in new participants with “additional skill sets [such as] inclusion, performance data and other aspects of modeling.” Industry stakeholders nominated six new members, of which NERC staff recommended five for addition to the team.

The exclusion of the sixth member, who like other nominees was only identified by number during the meeting, sparked questions from Robert Blohm of Keen Resources. Reading off background information provided to committee members, Blohm noted that the candidate was not recommended because their organization “did not support the candidacy [because] it didn’t have the resources … to allocate his time.” Blohm asked if the nominee could still participate in the SDT “if he’s willing to volunteer his own time and put in the effort,” perhaps as an observer.

Committee Chair Todd Bennett, of Associated Electric Cooperative Inc., said that while “each committee member [could] decide on their own” whether they agreed with Blohm, he would look at the employer’s feedback as “a non-supportive recommendation” if he were not an officer and had the ability to vote. Steve Rueckert, director of standards at WECC, said he understood Blohm’s reasoning, but he expected that NERC would already have asked the candidate for their willingness to participate and factored that into their recommendation.

Following his feedback, Rueckert moved for the committee to accept the original slate of five suggested by NERC. The motion passed unanimously.

Next on the agenda was Project 2024-01, which is intended to “address the definitions for generator owners and generator operators within the NERC Glossary of Terms to ensure the inclusion of [IBRs]” that meet recently approved registration criteria. (See FERC Accepts NERC ROP Changes, Drops Assessment Proposal.) Members were asked to approve a chair, vice chair and eight additional members to the SDT for the project.

Rueckert noted that NERC had received 11 nominees for the team and asked why only 10 were recommended. Calderon replied that two of the nominees were members of the same “representative body” and NERC felt that if both were included, it would reduce the diversity of the team.

Blohm argued for including the 11th candidate, observing that “only two candidates among the 10 recommended … have drafting team experience.” He suggested that the candidate, who has previously served as an SDT chair, would add valuable perspective to the team. He moved to amend the proposal to allow all the nominees to serve.

Members largely supported Blohm’s motion, which passed with no objections. Maggy Powell of Amazon Web Services was the sole abstention, saying she was “not particularly comfortable” with the idea of adding people to the team that were not recommended because it “discounts … the work that NERC has done to … vet these participants and [their] qualifications.”

The final project voted on at the meeting was Project 2024-03, which is working on the most recent changes ordered by FERC to NERC’s cold weather standards. NERC recommended a chair, vice chair and 11 members from the 18 candidates nominated by industry stakeholders.

Blohm again warned that the nominees seemed to lack experience serving on SDTs. He observed that of two candidates from the same company, NERC staff had recommended one with no drafting team experience over another who had previously served on SDTs. He suggested switching the two candidates and also adding another two industry nominees, which he said would “make a team of 14, eight members of which — in other words, a majority … would have drafting team experience.”

Members were receptive to Blohm’s suggestion, though there was considerable disagreement about the best parliamentary approach to handling the amendments. Rueckert reiterated Powell’s objection to “discounting NERC’s work based on a short [biography] that we’re seeing presented to us.” He also reminded members that inexperienced candidates could only gain experience by serving on SDTs.

The committee eventually compromised on switching out the two candidates from the same organization, while adding just one of the non-recommended nominees, resulting in a team of 13 total.

ISO-NE: New Mechanisms May be Needed to Ensure Future Grid Reliability

As the variability of generation and demand increases on the New England grid, market enhancements may be needed to promote dispatchable resources, ISO-NE told stakeholders at its Planning Advisory Committee meeting Aug. 21. 

“Current revenue structures may not adequately compensate resources for their value to the future grid,” said Patrick Boughan of ISO-NE, adding that the RTO plans to consider “the need for future market rule enhancements to support the ongoing reliability and economy of the region’s grid.” 

“While the precise nature of these enhancements requires further exploration, they could include new ancillary services intended to incentivize the resource attributes that will become more important as the clean energy transition continues,” he added. 

Curtailment likely will increase in the 2040s, reducing the value of new intermittent clean energy resources, ISO-NE found. An increasing amount of weather-based generation — coupled with increasing weather-based demand due to heating electrification — likely will make peak demand more variable.  

“Since the grid must be ready to serve load under the most extreme conditions, significant quantities of dispatchable resources will sit idle during milder winters,” Boughan said.  

As the renewables proliferate, the spring and fall seasons likely will be the first to decarbonize. By 2050, “almost all carbon emissions are concentrated in a handful of days in the winter,” Boughan added.  

At the PAC meeting, ISO-NE presented results from the Economic Planning for the Clean Energy Transition draft report. 

The study found that multiday storage will become particularly valuable with more renewables on the system, with 100-hour batteries becoming the most cost-effective way to reduce emissions by 2050. New solar resources are projected to be the least cost-effective. 

Dispatchable resources like synthetic natural gas and small modular reactors also would provide significant winter reliability benefits and would reduce the need to overbuild wind, solar and storage, Boughan said. 

“Eliminating carbon emissions through complete electrification of the heating and transportation sectors and a near-exclusive reliance on wind, solar and storage to generate electric power is possible but involves significant cost and unresolved reliability concerns,” Boughan said.  

2050 Transmission Study

Building on the results of the 2050 Transmission Study, Reid Collins of ISO-NE presented more information about the RTO’s modeling of different offshore wind points of interconnection (POIs).  

The original study and an additional consideration of different POIs modeled offshore wind during peak loads and at reduced outputs than nameplate capacity. (See ISO-NE Analysis Shows Benefits of Shifting OSW Interconnection Points.) Collins noted that several stakeholders requested that the RTO model offshore wind projects at full capacity.  

Collins said the analysis is “intended to give a rough estimate of total offshore wind that may be plausibly installed on system without significant curtailment.” 

When looking at individual POIs, ISO-NE found that 22 of the modeled interconnection points could handle an addition of 1,200 MW without upgrades. Just three POIs could go up to 2,000 MW without upgrades, while just one could go up to 2,400 MW. Some POIs would require minimal upgrades to reach these levels.  

“Based on the expected 2033 transmission system, a significant amount of offshore wind may be able to be connected without major upgrades or significant curtailment across a variety of potential POIs in New England,” Collins said. He stressed the need for coordination between the states, transmission owners, project developers and ISO-NE to interconnect offshore wind projects efficiently. 

More upgrades could be avoided if developers accept some degree of curtailment, or if projects are paired with storage or advanced transmission technologies to reduce curtailment, Collins said. 

He said ISO-NE plans to publish more detailed results on this analysis in the fourth quarter of this year. 

Asset Condition Projects

National Grid presented a pair of asset condition projects, with combined costs of about $120 million. The projects include: 

      • replacing components of the company’s Brayton Point Substation and relocating the transformers outside of the 100-year flood plain, with a projected cost of more than $40 million. 
      • a proposed refurbishment of a 345-kV line in central Massachusetts, with a projected cost of about $80 million. 

Avangrid detailed a $218 million increase in the cost of an asset condition project in Connecticut that initially was proposed in 2018. The project initially was estimated to cost $180 million but now is projected to cost nearly $400 million. The company said the cost increase is due to price escalation and inflation, along with an order by the Connecticut Siting Council to change the route of the rebuild to minimize visual impacts. 

Asset Condition Process Updates

Robin Lafayette of Rhode Island Energy gave an overview of the New England transmission owners’ work to improve the process for presenting asset condition projects to the PAC. The New England states have been pushing for more transparency and oversight into asset condition projects. 

The PAC does not have the power to approve or reject projects, but instead is intended to provide stakeholders with information on projects and to solicit feedback on proposals. 

Lafayette’s presentation focused on responding to feedback the TOs have received on the process updates, adding that the TOs will provide more detailed information on process updates in the fall.  

He said the feedback has clarified the need for standardization in asset condition project presentations. 

When assessing the health of transmission structures and equipment, “everyone is reporting on what appears to be a different grade scale,” Lafayette said. “What we’re proposing to do going forward is to all use the same rubric for structures, within the context of a PAC presentation.” 

He said TOs also plan to standardize how they present their evaluations of alternative solutions, including advanced transmission technologies. He added that the TOs plan to review and discuss ISO-NE longer-term planning studies when developing asset condition projects, to provide stakeholders with information on potential overlaps. 

A representative of the Connecticut Department of Energy and Environmental Protection said he’s “particularly interested in hearing more about how the TOs operationalize the feedback they have received.” 

Sheila Keane of the New England States Committee on Electricity, which has been vocal in pushing for more transparency and guardrails around the process, praised the TOs’ responsiveness to stakeholder feedback. (See New England States Raise Alarm on Eversource Asset Condition Project.) 

“What you’ve previewed sounds like it’s going in the right direction,” Keane said.

FERC Rejects Basin Electric Proposal for Crypto Rates

FERC on Aug. 20 rejected Basin Electric Power Cooperative’s proposal to establish cryptocurrency blockchain and large load rate schedules, though it did so without prejudice (ER24-1610).

The commission found that Basin had not met its burden to demonstrate that its proposal was just and reasonable and not unduly discriminatory or preferential. But it acknowledged that there are increasing utility and stakeholder concerns related to the growing number of large loads seeking electric services.

“While we reject Basin’s proposed revisions because Basin has failed to support them adequately, we are sympathetic to Basin’s concerns regarding its ability to serve expected load growth reliably and economically,” it said. “Therefore, our rejection herein is without prejudice.”

Basin’s board of directors on Feb. 16, 2024, approved the rate schedules and associated clarifying revisions needed to incorporate them into its Rate Schedule A. The changes had been in development for years and entailed three crypto rate schedules: one each for the SPP and MISO regions, and one for the Western Interconnection.

The co-op said it would procure energy for crypto loads in SPP and MISO at market prices and pass the costs onto its members, which would pass the costs onto the crypto loads. Basin said it would negotiate a rate with members for crypto loads that were within the Western Interconnection and outside of an RTO market.

To recover general and administrative costs, Basin wanted to assess an additional cost on members serving crypto loads.

Basin said the new schedules were necessary because of “the highly speculative nature of crypto loads,” their high degree of operational flexibility and their uneven, unpredictable load, all of which could result in stranded costs. It said its crypto load was 200 MW in 2023 and that more than 1 GW is expected to locate within its territory.

The proposed large load rate schedule would have applied to new or single-load expansions of 75 MW or greater that were not crypto-related. Basin said these large loads are similar to crypto loads, in that they are highly speculative, but that the nature of that speculation is different.

Projects such as direct-air carbon capture plants, hydrogen hubs and green ammonia factories might be spurred by federal or state legislation and be contingent on government funding, Basin explained. If that funding did not materialize, a project could be canceled, and Basin would be left to bear the cost of the generation and transmission assets acquired to serve it.

Basin said its members are in discussion with 22 large-load projects totaling nearly 5 GW, which is roughly equivalent to the co-op’s entire 2022 peak load.

FERC said that Basin did not provide adequate evidence that all crypto loads pose a greater stranded asset risk than non-crypto loads of similar size. It noted that Basin itself acknowledged that there is a stranded asset risk for non-crypto large loads as well and that the co-op does not have specific experience with stranded costs from existing crypto load within its territory.

Commissioners Lindsay See and Judy Chang did not participate in the order.

Basin did not respond to a request for comment.

San Francisco Ferry Operator Wins $5M Grant for ‘Charging Float’

Plans to transition California’s largest public ferry fleet to zero-emission vessels got a boost from a $5 million grant for charging infrastructure from the California Energy Commission.

The CEC awarded the funds Aug. 14 to the Water Emergency Transportation Authority (WETA), the agency that runs San Francisco Bay Ferry service. The funds will be used to install a “charging float” consisting of a dock, charger and battery storage.

The money was part of $87 million in grant funding the CEC voted to approve during the meeting. Much of the funding went to infrastructure projects for medium- and heavy-duty zero emission vehicles.

State’s Largest Public Fleet

With 15 vessels carrying about 3 million passengers a year across several routes, San Francisco Bay Ferry is California’s largest public ferry fleet.

The fleet runs on diesel, but WETA is planning a transition to zero-emission vessels through its Rapid Electric Emission-Free (REEF) program. The agency has set a goal of shifting half its fleet to zero emission by 2035.

Last month, the ferry service launched the MV Sea Change, a 75-passenger vessel described as the world’s first commercial passenger ferry powered completely by zero-emission hydrogen fuel cells. The California Air Resources Board funded the vessel’s development.

Owned by SWITCH Maritime, the hydrogen-powered ferry will run for a six-month demonstration period. Sponsors of the demonstration service include Chevron New Energies, United Airlines and the Golden Gate Bridge, Highway and Transportation District.

In November, the Federal Transit Administration awarded a $16 million grant to WETA for the electrification of four ferry floats. The project involves structural alterations to the passenger floats, installation of battery banks and vessel charging equipment, and grid connections.

WETA now plans to buy an electric ferry with funding from the Bay Area Toll Authority and the regional Metropolitan Transportation Commission.

Elsewhere on the West Coast, Washington State Ferries announced last month that it is partnering with ABB, a marine technology company, on the design and construction of five new hybrid-electric, 160-auto-capacity ferries. WSF, the largest ferry system in the U.S., has set a goal of running a zero-emission fleet by 2050.

Under mandates from the state legislature and governor, WSF will transition to hybrid-electric power by 2040.

Implementing Blueprints

WETA previously received CEC funding to develop a plan called a blueprint for transitioning to a zero-emission ferry fleet. The agency was one of 34 entities that completed blueprints for infrastructure to support medium- and heavy-duty zero-emission vehicles.

“To be able to move swiftly to deploy infrastructure for zero-emission vehicles, you actually have to have a plan,” Commissioner Patty Monahan said before voting for the WETA funding. “And you have to think about where you want to site it, how it fits with the grid.”

In addition to WETA’s ferry-charging project, the CEC voted Aug. 14 to approve funding for two other projects that came from the blueprints.

The city of Long Beach received $5 million for DC fast chargers and a battery backup system for the city’s medium- and heavy-duty truck fleet. Another $5 million went to Pilot Travel Centers for two rapid hydrogen dispensers and a hydrogen storage tank at a truck stop off Interstate 5 in Southern California.

The CEC awarded grant funding to an array of other projects on Aug. 14. Those include:

    • International Transportation Service received $3 million for hands-free EV charging stations at the Port of Long Beach, including a dynamic charging rail that can charge up to five yard tractors while they’re in operation.
    • Penske Truck Leasing received $7.9 million for chargers at two locations for its growing medium- and heavy-duty EV rental fleet.
    • Skycharger LLC received $10 million for EV chargers at the Port of San Diego for overnight and opportunity truck charging, as well as a 1.7 MW solar-powered microgrid and 1 MW battery storage system.
