The Bonneville Power Administration elicited nearly 150 comments in response to the March 6 draft policy outlining its decision to join SPP’s Markets+ rather than CAISO’s Extended Day-Ahead Market.
BPA’s tentative decision in favor of Markets+ offered little surprise to Western electricity sector stakeholders involved in the development of day-ahead markets in the West.
Still, the draft’s release ended nearly two years of speculation about a potential surprise — or whether the agency might succumb to political pressure and delay its choice to let developments play out around the West-Wide Governance Pathways Initiative’s efforts to bring more independent governance to CAISO’s markets. (See BPA Selects SPP Markets+ in Draft Policy.)
The torrent of comments have (so far) offered few surprises as well, with supporters of each market staking out the many of the same positions they’ve voiced since BPA kicked off its day-ahead market participation stakeholder process in July 2023.
RTO Insider’s round-up of the comments is by no means a comprehensive one, but we have sought to include many from key players in the industry and important constituencies. Additional comments were being posted to the BPA site throughout the day, and we will continue to review them for inclusion in future articles.
BPA officials have said they will respond to the comments and expect the agency to issue its final record of decision in early May.
‘Compelling’ Choice
Unsurprisingly, the consumer-owned utilities (COUs) that make up BPA’s base of “preference” customers largely supported the draft policy and urged the agency to finalize its decision without delay.
A common thread among the COUs backing the draft policy was the market governance issue, with some contending the Markets+ framework provides an independent governance structure that EDAM lacks.
For example, Gary Huhta, general manager at Cowlitz County Public Utility District, urged BPA “to proceed without delay” instead of waiting for the Pathways Initiative to wrap up “development of a partial independent governance structure.”
Pathways is developing a “regional organization” (RO) that will assume governance over EDAM and CAISO Western Energy Imbalance Market.
“BPA’s choice of Markets+ over CAISO’s EDAM is compelling, as its superior independent governance, uniform resource adequacy requirements, [greenhouse gas] design and a congestion revenue mechanism that promotes transmission investments,” Huhta wrote.
Snohomish County PUD shared Huhta’s sentiment. Snohomish noted that for Pathways to succeed, the California Legislature would have to support the initiative. And even if lawmakers back the proposal, Pathways “would not achieve full independence due to the remaining significant intertwining of CAISO and the new regional organization, including shared staffing and a shared tariff.”
“Under the proposal, CAISO would retain the dual roles of a participating balancing authority for one part of the footprint and the market operator for the full footprint that could result in a conflict of interest,” Snohomish contended. “Given the magnitude of trade likely to occur within day-ahead markets, and the potential influence of market rules and market operations over the allocation of costs and benefits of market participation, Snohomish has a strong preference for the fully independent governance structure of Markets+.”
Snohomish is also one of the signatories to the so-called “issue alerts” published recently to highlight the purported advantages of Markets+ over EDAM. (See 7th ‘Issue Alert’ Highlights Markets+ Footprint.)
The Western Public Agencies Group (WPAG), which consists of 27 COUs in Oregon and Washington, supported the draft policy. The organization noted that the policy comes as utilities prepare to sign new long-term provider-of-choice contracts slated to go into effect in 2028 and set the conditions under which BPA sells federal power to customers.
“BPA’s proposal to participate in a day-ahead market is the type of strategic progression needed to meet the moment and to secure the region’s long-term future,” WPAG wrote. “What is more, based on BPA’s extensive analysis, Markets+ appears to be the market for the job.”
Vancouver, Canada-based energy trader Powerex, a key Markets+ backer, said it “strongly supports” BPA’s draft policy, writing that it “reflects thorough analysis, extensive stakeholder input and a clear understanding of the long-term structural, operational and economic implications of organized day-ahead market participation.”
The company said also that it agrees with BPA’s conclusion that the SPP market is the best option “to protect the value” of the federal hydroelectric system and “uphold its statutory obligations, and promote a durable, fair and transparent market platform for Bonneville, its customers and the region.”
‘Ignores the Facts’
But the region’s two largest consumer-owned utilities by number of customers — Seattle City Light and Eugene Water and Electric Board (EWEB) — stood out among COUs in opposing BPA’s draft decision.
“BPA’s decision to join Markets+ does not comply with the agency’s statutory obligation to provide ‘the lowest possible rates to consumers consistent with sound business principles.’ Rather, BPA’s premature decision ignores the facts presented by its own record and analysis,” City Light wrote in comments that extended to 114 pages.
City Light reiterated the key concerns it expressed in a letter to BPA Administrator John Hairston last November after the agency played down the value of the results of a study it had commissioned to compare the potential economic benefits of participating in either market. (See Markets+ Leaning ‘Alarming,’ Seattle City Light Tells BPA.)
“BPA’s own economic analysis indicates that joining the California Independent System Operator’s Extended Day Ahead Market offers the largest benefits to its customers, followed by choosing to not join any day-ahead market,” the Seattle utility said.
City Light said Markets+ “is worse for BPA customers than EDAM by $165 million to $221 million annually — and these losses persist indefinitely into the future,” while continued participation in the WEIM only would provide $79 million to $130 million in greater benefits than joining the SPP market.
The utility also contended that “all available analysis” indicates that Markets+ will not provide the “well connected and integrated market footprint of diverse loads and resources” needed to deliver the maximum benefits for BPA customers.
“BPA’s decision eschews objective analysis and chooses which factors it elevates based on whether they support its preferred outcome. This is not consistent with sound business principles,” City Light said.
Oregon-based EWEB said it agreed with BPA about the need for independent market governance but contended that issue should not be the “sole factor” in the agency’s decision and “must be carefully weighed alongside the critical elements of transmission connectivity and market footprint.”
EWEB expressed concern about what it said are “the inefficiencies associated with a smaller, disconnected market like SPP’s Markets+.”
Like City Light, EWEB encouraged BPA to continue participating in the WEIM over joining Markets+, giving the agency time “to observe the ongoing evolution of EDAM and its progress toward independent governance.”
“By waiting, BPA can make a more informed, strategic decision that not only aligns with its operational goals but also strengthens regional collaboration. This measured approach ensures that BPA chooses the best long-term market option for both its stakeholders and the broader region,” EWEB wrote.
‘Narrow Set of Interests’
The draft policy also found little support among environmental organizations, with many urging BPA to pause or withdraw its draft decision.
In a joint letter, Earthjustice, the Northwest Energy Coalition and Idaho Conservation League said the proposed decision violates the National Environmental Policy Act and the Pacific Northwest Electric Power Planning and Conservation Act.
The trio argued that BPA failed to consider the environmental impacts of its choice in violation of NEPA, noting that the agency has committed “up to $40,000,000 as part of the collateral for a bank loan to support the development of Markets+. The promise to pay these funds is irrevocable, and they will be forfeited if BPA withdraws from Markets+. This commitment of resources prior to any environmental review is contrary to NEPA.”
The groups argued BPA violated the latter act by ignoring the “substantial cost savings of a decision to join EDAM” and instead prioritizing Markets+’s governance design. They pointed to two production cost studies showing that EDAM could provide significant savings for BPA customers under certain scenarios. (See BPA Sticks to Markets+ Leaning Despite Study Showing EDAM Benefits.)
In urging BPA to withdraw its draft policy, the groups wrote that the agency’s “response to public input has been minimal, and its decision-making process has been opaque and appears more focused on catering to a narrow set of interests rather than the broader public good. BPA, however, has a legal duty to serve the best interests of the entire Pacific Northwest, including, among others, the region’s energy, environmental and economic interests.”
Other environmental groups similarly opposed the draft decision. Save Our Wild Salmon Coalition, Sierra Club, Oregon Clean Grid Collaborative and Renewable Northwest all opposed the draft decision in separate letters.
The Washington BlueGreen Alliance, a coalition of labor unions and environmental groups, said BPA did not “fully consider” how its decision would affect not just preference customers, but the Northwest region at large.
“We are concerned that the BPA draft decision to join Markets+ is based on an inadequate analysis of each day-ahead market’s governance structure and economic costs to the region, which will have significant consequences for our region’s climate policies and workers,” the group said.
They also argued that the “fragmented nature” of the Markets+ footprint is likely to result in a less reliable system or require customers to pay more to ensure uninterrupted delivery.
“Substantial increases in BPA’s costs have a direct effect on industrial manufacturing growth and job creation in our states. These costs will likely be passed on to ratepayers, and the impact will be felt most acutely by large energy users, such as industrial and commercial ratepayers,” the group wrote.
Tribal Perspectives
Many of the region’s tribes had their own reason to oppose BPA’s decision and urge postponement, saying they were unable to provide informed — and legally required — consent because of the agency’s lack of “government-to-government consultation” with tribal representatives.
“The federal government’s trust responsibility obligates BPA to ensure that tribes are full partners in managing the lands and resources that are our ancestral inheritance,” the Snoqualmie Tribe in Washington wrote, adding that “tribal values, priorities and rights must be integrated into the” day-ahead market.
Washington’s Yakama Nation urged BPA to delay until it “has engaged in full in meaningful consultation” with the tribe to ensure that participation in a day-ahead market does not “negatively impact” the Yakama’s treaty-reserved resources and rights.
The Confederated Tribes of the Umatilla Indian Reservation expressed similar concerns, pointing to potential risks to its members’ fishing rights on the Columbia River from changes in BPA’s operations.
The Alliance for Tribal Clean Energy echoed those concerns, while also contending BPA’s decision was “rushed.”
“BPA’s accelerated timeline precludes the thorough evaluation of alternative market options that might better align with tribal interests and environmental considerations,” the alliance wrote.
Tech Views
Tech companies and data center developers, including Google, Amazon, Microsoft and Rivian, signed a letter by the Clean Energy Buyers Association asking BPA to postpone its decision.
The companies contended more analysis is needed to consider studies that show a “wide range of potential outcomes, especially the potential for increased systems costs, creates confusion and significant uncertainty for ratepayers.”
“Retail customers in Bonneville’s service territory deserve greater assurance that participation in a [day-ahead market] will not drive undue costs, ultimately borne by ratepayers,” the companies wrote.
They also wrote BPA should wait until the outcome of Pathways, while noting that staffing issues at BPA pose challenges. (See BPA to Restore 89 ‘Probationary’ Staff, Agency Confirms.)
Amazon, which has invested billions of dollars toward the development of data centers in Oregon, issued a separate letter. The company said BPA’s justification for its draft policy “is not sufficient to meet the important threshold of ratepayer protection, particularly in light of other market options available, some of which have been reported by Bonneville studies to save customers hundreds of millions compared to the Southwest Power Pool’s Markets+.”
The company said BPA should hold off on joining a day-ahead market and remain in CAISO’s WEIM while it evaluates its options.
‘Seamless’ Market
CAISO weighed in as well, noting the estimated $97 million in benefits BPA has earned since joining the WEIM in 2022 and pointing to that market’s contribution to increasingly coordinated transmission flows across the Northwest, which it said has resulted in $1.5 billion in estimated benefits for the entire region.
“The seamless real-time operational market created between the Pacific Northwest and other WEIM balancing areas in the West has also become an invaluable tool in supporting system reliability, especially during stressed system conditions, which have increased in frequency and intensity in recent years,” CAISO wrote.
CAISO also questioned BPA’s treatment of the governance issue in its draft, saying the document does “not fully present and consider the enhancements to the ISO’s market governance that will take effect upon implementation” of the Pathways Initiative’s “Step 1” changes to that governance.
The ISO said BPA’s draft additionally neglected to discuss “limitations” SPP has placed on the governance authority of the Markets+ Independent Panel, an issue important for “comparative governance analysis.”
“While the [Markets+] tariff contemplates that the SPP board will give significant deference to the MIP’s decisions, the SPP board nonetheless retains broad authority to overturn such decisions,” CAISO wrote.
