Washington, D.C. - Oregon's U.S. Senators Jeff Merkley and Ron Wyden, and Washington's U.S. Senators Patty Murray and Maria Cantwell today sent a letter urging the Bonneville Power Administration (BPA) to make a careful, deliberate decision about which power market to join. Currently, the BPA is considering joining one of two electricity markets: the California Independent System Operator (CAISO)'s Extended Day-Ahead Market (EDAM) or the Southwest Power Pool (SPP)'s Markets+ day-ahead market. These markets provide opportunities for power suppliers to meet customers' electricity needs at fair prices during peak energy demands by buying excess electricity from, or selling it to, neighboring market participants.
In their letter to BPA Administrator John Hairston, the Senators wrote: "A reliable, affordable and sustainable energy system is necessary for the economic and environmental welfare of the Pacific Northwest. The decisions BPA makes now will have lasting consequences on the modernization and expansion of the electrical grid and energy generation resources across the West. Further, they will significantly impact the region's ability to adapt to extreme weather events and climatic uncertainty in the future. BPA's decision to join a day-ahead market is monumental-BPA must be able to demonstrate that it is in the best interests of communities across the Northwest that are reliant on BPA for both power and transmission services."
The Senators asked BPA a series of questions about its plans to join either EDAM or Markets+, emphasizing the necessity of a reliable, resilient, and clean electrical grid for the economic and environmental goals of the Pacific Northwest.
"Given the critical importance of this decision for the region, we want to be crystal clear: this letter should not be construed as favoring one market over the other. We share a strong belief that any decision of this magnitude warrants thorough evaluation of all options, including joining neither market at this time. BPA should refrain from making any draft or final decisions until there is less uncertainty and BPA can prove that any decision will provide the greatest benefit to the entire Northwest," they concluded.
BPA markets and transmits power generated at 31 federal hydropower projects, the Columbia Generating Station, and several other non-federal power plants. The agency also operates and maintains nearly three-fourths of the high-voltage electricity transmission throughout Washington, Idaho, and Oregon, as well as parts of California, Nevada, Utah, Wyoming, and Montana. It primarily provides power to rural electric cooperatives and public power utilities serving consumers throughout the Pacific Northwest.

Dear Administrator Hairston,
We have heard concerns from across the Pacific Northwest regarding the Bonneville Power Administration's (BPA) anticipated decision to join one of two electricity markets: the California Independent System Operator (CAISO)'s Extended Day-Ahead Market (EDAM) or the Southwest Power Pool (SPP)'s Markets+ day-ahead market. BPA's participation in either market will have major impacts across the West for decades to come. We urge you to act carefully and deliberately.
A reliable, resilient, and clean electrical grid is essential to meeting the economic and environmental goals of the Pacific Northwest. Electrifying our transportation system, buildings, and meeting the demands of our growing manufacturing and data center industries will require access to additional power resources. In tandem, we must ensure that Northwestern residents and businesses continue to receive reliable, clean energy that will keep their lights on and their homes comfortable in the face of increasingly frequent extreme weather events.
In light of these major challenges, we share your view that "Bonneville's customers and electricity consumers across the Pacific Northwest may achieve more benefits from participants coalescing around one regional market in the West." Further, we strongly believe that competition between the two day-ahead markets has improved both offerings, to the benefit of BPA and the region's ratepayers. Nonetheless, there are still a number of uncertainties associated with both EDAM and Markets+.
The CAISO EDAM was only approved by the Federal Energy Regulatory Commission (FERC) in December 2023, and there are still outstanding market governance concerns. We want to recognize the critical role that BPA has played to move governance reforms forward. The firm position taken by BPA that governance reforms were necessary helped inspire the West-Wide Governance Pathways Initiative last year. We see this effort has made real progress, culminating with NV Energy's recent announcement that it intends to join EDAM. Signing of the market implementation agreements will trigger Step 1 of the governance changes proposed in the Pathways Initiative.
Meanwhile, the SPP Markets+ tariff was filed at FERC in April and is still under review. FERC has a new slate of commissioners, and it remains unclear whether the tariff, as submitted, will be approved or found deficient. Indeed, deficiency letters for novel filings are common and require additional time and effort to resolve. Further, the creation of market seams between Markets+ and EDAM-unique given the underlying transmission framework at play with separate balancing authorities and tariffs-may prove challenging to resolve, leaving ratepayers unable to realize economic and reliability benefits.
Given ongoing uncertainties and the changing landscape with regard to both day-ahead electricity markets, we are concerned that BPA has expressed a preference for one market before complete and final information is available for clear decision making. To help us understand BPA's current leaning, please provide answers on a question-by-question basis by August 25, 2024.
A reliable, affordable and sustainable energy system is necessary for the economic and environmental welfare of the Pacific Northwest. The decisions BPA makes now will have lasting consequences on the modernization and expansion of the electrical grid and energy generation resources across the West. Further, they will significantly impact the region's ability to adapt to extreme weather events and climatic uncertainty in the future. BPA's decision to join a day-ahead market is monumental-BPA must be able to demonstrate that it is in the best interests of communities across the Northwest that are reliant on BPA for both power and transmission services.
Given the critical importance of this decision for the region, we want to be crystal clear: this letter should not be construed as favoring one market over the other. We share a strong belief that any decision of this magnitude warrants thorough evaluation of all options, including joining neither market at this time. BPA should refrain from making any draft or final decisions until there is less uncertainty and BPA can prove that any decision will provide the greatest benefit to the entire Northwest. Thank you for your consideration and prompt attention to these questions.
