With California lawmakers passing the bill designed to transition the governance of CAISO’s markets to an independent “regional organization” (RO), new challenges await the West-Wide Governance Pathways Initiative as the coalition seeks to turn a once-elusive goal into reality.
In an interview with RTO Insider, Kathleen Staks, co-chair of the Pathways Initiative’s Launch Committee and executive director of Western Freedom, discussed the future of the multistate RO that will oversee CAISO’s Western Energy Imbalance Market (WEIM) and Extended Day-Ahead Market (EDAM), the latter set to launch in 2026.
Nine state utility commissioners and energy officials launched the Pathways Initiative in a July 2023 letter outlining their desire for increased coordination and expansion of electricity markets in the West. (See Regulators Propose New Independent Western RTO.)
The primary obstacle to realizing that goal has been California’s oversight of CAISO, which operates the markets and whose Board of Governors is appointed by the state’s governor.
“Nobody wants to participate in something where one state has the ability to choose the governing body members,” Staks said.
Previous legislative efforts to regionalize CAISO have failed because those asked California to completely relinquish control of CAISO’s balancing authority and transmission functions, Staks explained.
Pathways took a different approach. Over the course of 18 months, Staks and her team designed the RO to only oversee CAISO’s markets while preserving the ISO’s role in planning California’s grid.
The California legislature voted to approve the initiative’s “Step 2” plan on Sept. 13, authorizing the ISO and California’s investor-owned utilities to participate in the RO. (See Pathways Bill Passes Calif. Legislature in Lopsided Votes.)
But the work is far from over.
“It’s one thing to get the bill passed,” Staks said. “It’s another thing to actually get the thing off the ground. The implementation part still has to happen as well.”
For example, the RO has yet to be incorporated, and the Launch Committee is still drafting the bylaws and policies that will guide the organization. Additionally, FERC must approve the tariff change, and the committee must seat a board and find an executive director.
All those tasks will take time and money.
The group, which has estimated a $7.1 million budget for all three of its phases, hit a financing snare early in 2025 when the Trump administration paused nearly $1 million in funding as part of a larger spending freeze on projects previously promised support by the Biden administration.
There is enough money in the bank to cover expenses through the end of 2025, but the committee needs roughly $2 million for 2026 and about $4.8 million for 2027, staff said during an Aug. 29 meeting.
The group has issued an updated pledge form and a draft funding agreement to solicit additional funding, and it also is considering debt financing as an option.
“Fundraising is not going to be easy,” Staks said. “But I also think that, again, the economic benefits of getting this done and having one large, independently governed market for the West are good enough that we will be able to overcome that hurdle.”
Keeping the Door Open
However, the West will, at least for now, have two day-ahead markets. Because in tandem with CAISO’s EDAM, SPP is developing an alternative day-ahead market for the region — Markets+. SPP is also developing a Western version of its Eastern RTO called RTO West.
Major utilities like PacifiCorp, Portland General Electric and the Los Angeles Department of Water and Power have committed to EDAM.
Meanwhile, entities such as Xcel Energy subsidiary Public Service Company of Colorado, El Paso Electric, Tacoma Power and the Bonneville Power Administration have agreed to join Markets+. (See BPA Chooses Markets+ over EDAM.)
Despite utilities committing to either EDAM or Markets+, Staks said there is still a possibility for a unified market in the West. Utilities could decide to leave the SPP option and instead join EDAM, which has a larger market footprint, Staks noted.
The success of AB 825 “keeps the door open” for creating a larger market in the West, and ultimately an RTO, she said.
The bill “crosses off one of the barriers that have existed for so long … for utilities to decide to join and to go further with a market that is governed by California,” Staks added.
Supporters of EDAM have pointed to production cost studies by The Brattle Group and Energy and Environmental Economics that have found that CAISO’s market option would save ratepayers millions of dollars more than Markets+. (See Brattle Study Finds EDAM Gains, Markets+ Losses for BPA, Pacific NW.)
For example, an October Brattle study found that BPA would earn $65 million in annual benefits from EDAM but face $83 million in increased yearly costs from participating in Markets+.
BPA and other Markets+ supporters have argued the production cost models have limitations and cannot capture the full economic picture. Additionally, BPA staff have pointed to Markets+’s resource adequacy requirements, greenhouse gas accounting mechanisms and especially its independent governance model. (See Western Utilities Set Sights on RTO After DAM Choice.)
After AB 825 passed, BPA told RTO Insider that the bill is a “positive development toward a more equitable market landscape in the West,” but maintained that Markets+ will provide greater benefits for its customers.
“While Bonneville participated in the development of several important provisions in the Pathways Initiative — like broader stakeholder engagement and the assurances for public purposes — BPA has been and remains clear in its desire to participate in a market wholly separate from the authority of any single state or entity,” BPA said.
However, Staks noted that U.S. senators from Oregon and Washington, along with stakeholders in the region, urged BPA to wait for the Pathways Initiative to play out, which the agency did not do.
Citing stakeholder comments, Staks said, “If governance is such a problem, why wouldn’t you wait for the Pathways Initiative, for the California legislative process to happen?” (See BPA Flooded with Comments on Draft Day-ahead Market Decision.)
“I think the response from BPA has generally been, ‘yeah, we don’t even think that the Step 2 proposal goes far enough, it’s not independent enough,’” according to Staks. “I’m not even sure what to say to that.”
“The new RO has sole authority over the EIM and EDAM,” Staks contended. “I don’t know how you get more independent than that.”
She acknowledged the RO will initially be under CAISO’s tariff, “and so there are some challenges inherent in that.”
“But that does not mean that the governance over the market is not … fully independent, because it is, and that was the design,” Staks said.
“We have that [independence] in Markets+, BPA spokesperson Kevin Wingert told RTO Insider. “Markets+ continues to demonstrate the effectiveness of its Western participant-led governance.”
Scott Simms, executive director of the Portland, Ore.-based Public Power Council, which strongly urged BPA to join Markets+ throughout the agency’s decision process, said the passage of AB 825 did not address the organization’s concerns about EDAM’s governance or affect its evaluation of the two options.
“PPC, and other Western entities including BPA, have been very clear about our concerns with the continued relationship between the future regional organization and CAISO under the Step 2 proposal, which prevents establishing truly independent governance over EDAM,” Simms said in an email.
‘Erosion of Trust’
The next steps for the Launch Committee include continuing to support the development of the RO until an independent board is brought on around July 2026. The board will not have power over markets until FERC approves the tariff, but it will assume authority over the RO to pick an executive director, negotiate the service agreement between CAISO and the RO and design the overall strategic plan for the RO moving forward.
The committee will continue to exist to support the board and make recommendations, “but ultimately, those decisions will be made by this independent entity starting next summer,” according to Staks.
“Once we have the RO set up and it has the market authority, then the Pathways Initiative has been successful,” Staks said. “And then we take a victory lap and see what else needs to be worked on.”
The committee consists of representatives from all sectors in the Western power industry that have an interest in developing electricity markets in the region. Staks said the effort is a testament to the importance of collaboration.
She said the debate over EDAM and Markets+ has created an “erosion of trust” and forced people into camps.
“We have an opportunity now, and we have a mandate now to rebuild those relationships,” Staks said. “Because whether we have one market or two, we’re going to have to find a way to work together, because the challenges are too big for us to be divided.”
The country faces “almost existential” challenges, Staks said. She pointed to difficulties of building new infrastructure, the changing generation mix, load growth and “inconsistent policies” coming out at the federal level that are targeting the renewable energy sector along with tariffs impacting supply chains.

“We have not just common ground, but universal agreement that we must be able to provide affordable, reliable energy to our consumers,” Staks said. “Those are fundamental tenets for every state in the West. Those are not political issues. Affordability and reliability are imperatives. And if we can peel away the rest of this noise and come back to those two fundamental tenets, I think we’ve got a good platform to rebuild trust and relationships again.”
