Episode Summary
Executive Summary: The episode examines California’s AB 825 and the Pathways Initiative, which aims to create a voluntary Western energy market by evolving the existing CAISO-run real-time market into a broader regional organization (ROE). Guests Brian Turner and Kathleen Stacks argue that the West’s fragmented balancing authorities waste money and reduce reliability, but governance, state sovereignty, FERC politics, and competing market proposals (SPP’s Markets+) make the path controversial and incremental.
Main Topics: Why a larger Western market matters (Priority: 5/5): The host and guests frame regional electricity markets as a basic efficiency tool: broader geography smooths supply/demand variability, lowers costs, and improves reliability. The West’s fragmentation into 38 balancing authorities is presented as a structural problem the market is designed to solve. The Energy Imbalance Market as the proof of concept (Priority: 5/5): The Western Energy Imbalance Market (EIM) is described as the 5- and 15-minute real-time market that launched in 2014 and proved the concept. It now covers most Western demand and has built trust for expanding into day-ahead markets. Pathways, ROE, and the governance redesign (Priority: 5/5): AB 825 moves forward a new regional organization, ROE, that will take governance authority over the EIM and day-ahead market while CAISO continues operating the software and infrastructure under contract. The design intentionally separates governance from operations. Competing market structures in the West (Priority: 4/5): The Southwest Power Pool’s Western EIM and Markets+ are competing day-ahead market efforts. Bonneville Power Administration’s choice of Markets+ is a major setback and could create an inefficient bifurcated market unless it reverses course. State sovereignty, public policy, and stakeholder power (Priority: 5/5): A major theme is how to preserve state energy policy in a multistate market. The proposed structure embeds public-interest and state-policy representation in governance, seeks voluntary participation, and emphasizes easy exit without penalties. Risks from FERC, Trump-era politics, and capacity markets (Priority: 4/5): The guests discuss concerns that a Trump-aligned FERC could use market rules to pressure clean-energy states or fossil-fuel interests. They say the current design does not add jurisdiction, avoids capacity markets for now, and relies on voluntary service layers and resource adequacy coordination. Incremental expansion toward a full RTO (Priority: 4/5): The initiative is designed as a stepwise path: first governance over existing markets, then expansion of services like ancillary services, transmission planning, interconnection studies, and possibly eventual balancing-authority consolidation—if states choose to opt in.
Key Arguments: Regional electricity markets reduce costs and improve reliability by pooling diverse resources and loads across a wider geographic area. The EIM demonstrates that the West can cooperate successfully in a limited, low-risk way before taking on the more politically sensitive day-ahead market. Separating market governance from market operations is the key innovation that makes a Western regional market politically feasible. Voluntary participation and no-penalty exit are essential in a region where states and utilities are highly protective of sovereignty. The ROE is designed to embed state-policy review and public-interest participation so that market rules do not override state clean-energy or resource policies. Markets should not force a state to consume power it does not want; instead, the market should respect each state’s policy choices while still enabling economic dispatch. The biggest risk to the West is not just politics but fragmentation: competing day-ahead markets create costly seams and reduce the value of regional coordination. Capacity markets are intentionally not part of the near-term design because many Western stakeholders view them as a possible fossil-fuel subsidy and because resource adequacy is being handled through separate voluntary structures. Bonneville’s decision to join Markets+ rather than the CAISO-linked path is economically costly and may still be reversible. The new process aims to learn from older RTOs/ISOs by adding more stakeholder access, public participation, and periodic review, even if that slows decisions down.
Data Points: Balancing authorities in the West: 38 - The West is described as having 38 separate balancing authorities rather than one larger regional market. Coverage of the Western Energy Imbalance Market: 80% of Western electricity demand - The EIM is said to now cover roughly 80% of electricity demand in the West. Value generated by the EIM: $8 billion - Guests say the EIM has generated about $8 billion in value for participating utilities. EIM launch year: 2014 - The real-time market is described as launching in 2014 after development beginning around 2010-2012. First mention of the market idea by host: June 2016 - David Roberts says he first wrote about a Western regional market in June 2016. California legislation: AB 825 - The bill passed in California to advance the Pathways Initiative and establish the next phase of regional market creation. New regional organization name: ROE (Regional Organization Western Energy) - The new governance entity is repeatedly referred to as ROE. Initial board seating timeline: July 2026 - The guests say the new organization will incorporate in January 2026 and seat its initial board by July 2026. Expected FERC/governance authority timing: January 2028 - They estimate the new regional organization will have full authority after tariff changes, likely around January 2028. Markets+ go-live: Fall 2027 - SPP’s Markets+ day-ahead market is described as scheduled to launch in fall 2027. Potential Bonneville-related savings: $700 million/year - A Brattle study is cited as showing this level of savings for California if Bonneville participates in the CAISO-linked path. Savings without Bonneville: about $300 million/year - The expected savings drop substantially if BPA does not participate. Bonneville region loss under Markets+: $200 million/year - Brian Turner says BPA’s own studies show the Bonneville region loses roughly $200 million annually by choosing Markets+. Broader Northwest loss under Markets+: $400 million/year - Turner says the broader Northwest loses about $400 million annually relative to the CAISO-linked alternative. BPA transmission buildout: 1 mile in 5 years - Kathleen Stacks says BPA has built only about one mile of transmission over the past five years.
Pivotal Quotes: "The more area it covers, the more stable, reliable, and low-cost it will tend to be." — David Roberts: Opening framing for why larger regional electricity markets are beneficial. "We created it in 2010, 2011, 2012... [and] since then, we've seen tremendous success." — Brian Turner: Explaining the origins and performance of the Western Energy Imbalance Market as the seed of Pathways. "It is all voluntary. You can get in, you can get out." — Kathleen Stacks: Describing the market’s voluntary structure and exit rights to reassure skeptical states and utilities.
Implications: If successful, the West could gain a more efficient, lower-cost, and more reliable electricity market without forcing states to surrender policy control. But competition, governance fights, and federal politics could still leave the region fragmented and less efficient.
