“At its core, our GHG design allows states to reflect their preferences and policies without impacting other states,” Gilbert said, summarizing the ISO approach and noting the design has been in use in the Western imbalance market since 2014 to reflect California’s cap‑and‑trade program.

Gilbert explained that resources located inside a GHG jurisdiction embed compliance costs in their energy bids, while resources outside that jurisdiction may elect hourly to offer into GHG areas and, if dispatched to serve those areas, receive an explicit marginal GHG payment. The ISO said it also provides data to support state compliance programs and regulators’ monitoring needs.

Utah staff raised concerns that GHG pricing and related reporting requirements could create leakage or disadvantages for non‑GHG balancing areas. Gilbert and other ISO staff said the market design limits price impacts to the GHG area’s bid stack and noted that states have post‑hoc methods to calculate leakage; California’s system operator and regulators have previously described settlement processes intended to quantify and address leakage in certain circumstances.

Commission staff and ISO presenters also discussed recent state‑level legislative and regulatory inquiries. Anya Gilbert and Stacy Crowley said the ISO had communicated with state regulators — including the California Air Resources Board — about whether wholesale market participation would trigger statutorily required emissions reporting, and ISO staff said they would follow up with regulators to clarify obligations under state laws and pending rules.

The GHG framework, the ISO said, is voluntary for resources; it is designed to let states impose their own compliance cost signals while maintaining price formation that keeps impacts geographically contained to the state or jurisdiction that adopted the policy.","mediaType","Video","parentTitle","Meeting with CAISO Representatives","oneSentenceSummary","The California ISO told Utah regulators that its greenhouse‑gas bid framework lets resources reflect state GHG compliance costs and that marginal GHG costs, when dispatched, are paid by load in the GHG jurisdiction — not by the broader market.","taxTitle","Utah Public Service Commission, Utah Subcommittees, Commissions and Task Forces, Utah Legislative Branch, Utah","taxId",72399,"location","Utah","headline","shortSummary",{"_33":76,"_35":36,"_37":38,"_39":77,"_41":78,"_43":79,"_45":80,"_47":81,"_49":82,"_51":83,"_53":84,"_55":56,"_57":58,"_59":85,"_61":62,"_63":64,"_65":86,"_67":68,"_69":70,"_71":72,"_73":56,"_74":56},6199792,"California ISO officials brief Utah regulators on WEIM benefits and EDAM go‑live plan",2655,569000,3224000,"/Search/View?dp=1&key=3823144-9acae3ebff48351e35425035dd0fa507&start=569&end=3224","https://assets.pipeline.soar.com/3823144-9acae3ebff48351e35425035dd0fa507/thumbnail_569000.jpg","/articles/6199792/Utah/California-ISO-officials-brief-Utah-regulators-on-WEIM-benefits-and-EDAM-golive-plan","https://secure.pipeline.soar.com/6199792-18a5c8e12406750b147af8858a1813ad/orig.mp4?Expires=1770451499&Signature=NVVyOzW7xhMvnP-68OY~Lg1zxeRh~g-djtM7mOgDf46jxWG9-92jdDl3WsZtPwY1Af~On~yRmV4OCqIMU6GtvzdxdTkdEgIH2YcUjCP1Dw5Aoz38z8n6a9DLf-pggbhuItTqVjUcWPjxKlPrsGeaNDdfMFwiLqocz7ujh7PIeEsbUNTvepvWPuYZNDjeQAl1cAwq4N1KK3kFgQxGOKJSo9DWsYs6qEL80v~tCzsP-07VpkRR5vfDHJs3WsJTBdZRz4MxNE3jJ22znrlCN7Fr5kdayJls1f~7mwDSr70DNXCrjNL32-Q40PIW0c6bllPBYqjbor1sHBai4-DrzUXm8g__&Key-Pair-Id=KUT5TJCACFTXG","California ISO officials told the Utah Public Service Commission on the record that the Western Energy Imbalance Market (WEIM) has produced multibillion‑dollar economic benefits and that the ISO is on track to launch its Extended Day‑Ahead Market (EDAM) with Pacific‑core participants in May 2026.

“We facilitate market trades, but we do not act as a market participant,” said Anna McKenna, vice president of market design analysis for the California ISO, describing the ISO’s role as neutral operator of the grid and markets.

The briefing covered three operational items that the ISO said drive WEIM benefits: a large, geographically diverse pool of resources that reduces production costs; real‑time optimization every 15 and 5 minutes that helps manage changing weather and renewables; and procedures that test participant readiness so the market produces feasible dispatches. Anna McKenna said WEIM has produced more than $7 billion in estimated economic benefits since 2014 and cited improved reliability and lower emissions as additional outcomes.

Anya Gilbert, lead policy developer at the ISO, and Milos Kosanec, regional market sector manager, described EDAM as a voluntary day‑ahead market that would extend least‑cost, portfolio‑level optimization across a larger Western footprint. The ISO’s planned EDAM functions include an integrated forward market (financial clearing), a residual unit commitment that ensures reliability if the market alone does not produce feasible schedules, and separate pricing for uncertainty. The ISO confirmed Pacific‑core entities are the initial set for EDAM go‑live in May 2026 and listed other expected implementation dates for later participants.

The ISO explained procedures intended to limit operational risk if an entity cannot show sufficient forward resources. The day‑ahead “resource efficiency evaluation” tests whether each participant can meet its forecasted load and uncertainty; ISO staff said the test is run before day‑ahead clearing and uses a high percentile forecast to capture uncertainty. If an entity fails, staff said there is a tiered set of consequences, opportunities to “cure” the deficiency, and a fallback to real‑time WEIM testing if the problem persists.

The ISO also described the assistance energy transfer product that lets entities opt in to pay a defined surcharge when they exceed prior transfer levels during tight conditions. Holly Taylor of the ISO said the surcharge is calculated after market clearing and is tied to a cap price (roughly in the thousands of dollars per unit in the emergency pricing example the ISO described); entities opt in by day for standard use and the product has been used by roughly 10–11 balancing areas at times.

Utah Division of Public Utilities staff asked about detailed benefit calculations and the ISO said it publishes a methodology and quarterly reports and performs counterfactual analysis comparing market outcomes to a no‑market base schedule case. The ISO agreed to provide links and quarterly detail to commission staff.

The ISO asked stakeholders to weigh operational and design choices as EDAM is implemented and said it will continue stakeholder engagement and monitor effects after go‑live. Officials invited regulators and staff to follow‑up technical workshops and training sessions planned before implementation.

The ISO’s presenters at the briefing were Anna McKenna (California ISO, vice president, market design analysis), Anya Gilbert (California ISO, lead policy developer), Milos Kosanec (California ISO, regional market sector manager), Holly Taylor (California ISO), and Stacy Crowley (California ISO, vice president of external affairs).

Crowley said the ISO evolved a joint governance model to include a Western Energy Markets governing body that shares authority with the ISO board. Under a step‑1 package approved last summer, the governing body’s role was elevated with a new mission emphasis on consumer interest and preservation of state and local authority, plus a dual‑filing dispute mechanism for FERC if the board and governing body disagree.

\"We expect that trigger to be met very soon,\" Crowley said, referring to the step‑1 implementation trigger the ISO set (sufficient outside‑California load and geographic diversity among EDAM participants). If that trigger is reached, primary authority over market rules would shift toward the governing body, ISO staff said.

Crowley described step 2 as a possible transfer of market‑rule governance to a separate regional organization that would be independent of the ISO’s corporate structure while the ISO would continue to operate the market’s systems and control center. She said the step‑2 path is reflected in California Senate Bill 540, which authorizes tariff changes that would permit a regional governance arrangement but requires statutory criteria be met before the ISO’s board could approve a transfer.

ISO officials said SB540 passed the California Senate unanimously but that an amendment creating a five‑member regional oversight council was inserted in the assembly and drew objections from supporters of the original proposal. The ISO indicated it is working with California legislators and stakeholders to revise the bill language before the assembly’s committee deadlines.

The ISO said it will continue stakeholder outreach, retain existing independent market‑monitoring and surveillance structures, and revisit governance choices depending on implementation experience and the pace of EDAM expansion.","ISO officials told Utah regulators that a stepwise governance plan would elevate an independent Western Energy Markets governing body under step 1 and could move market‑rule governance to a separate regional organization under step 2, a change that is tied to California legislation (SB540).",{"_33":100,"_35":36,"_37":38,"_39":101,"_41":102,"_43":103,"_45":104,"_47":105,"_49":106,"_51":107,"_53":108,"_55":56,"_57":58,"_59":109,"_61":62,"_63":64,"_65":110,"_67":68,"_69":70,"_71":72,"_73":56,"_74":56},6199783,"ISO advances targeted change to congestion‑revenue allocation to protect transmission customers",1553,6067000,7620000,"/Search/View?dp=1&key=3823144-9acae3ebff48351e35425035dd0fa507&start=6067&end=7620","https://assets.pipeline.soar.com/3823144-9acae3ebff48351e35425035dd0fa507/thumbnail_6067000.jpg","/articles/6199783/Utah/ISO-advances-targeted-change-to-congestionrevenue-allocation-to-protect-transmission-customers","https://secure.pipeline.soar.com/6199783-b1aa8aa1c10110c08f6478cd884b7e53/orig.mp4?Expires=1770451499&Signature=BZ9kobTwUdgDnOkNam4dc3J1PXI4XAvT-u2oGBSPrEh5LrtVjERM-yZUcZpc-ctcjK8Tk4IrCnRVZBuZw5RUOvNz249ebgyJ5YaL6Ppnu0xWJAcQRX86yTvCxCM6hvRFfZiCQfbO-sH3owrfW1MYmt~FuHd1~iAfAjAv3kUCXbCO4fYUupv7B5xYBSzQ6Bs3L3hYE9UvoOq0NpqbCJLqLqkf9MWUwK7P16ixtI7IBclR6Jv1ngeCA0LPr~VZLJQ2NtkMoJzTAzjkmDbF-KF7jg7NeqAprHbUGIBI0Y1Ev0rekP2RMIuB7DausjK5aSbQ6PXsgIDnjHaGnqw6LkgRbw__&Key-Pair-Id=KUT5TJCACFTXG","Milos Kosanec, regional market sector manager at the California ISO, told Utah regulators the ISO has developed a targeted change to congestion‑revenue allocation intended to address stakeholder concerns about parallel‑flow congestion in the EDAM design.

The ISO explained that locational marginal prices (LMPs) have three components: energy, congestion and losses. The difference between the LMP paid to a generator and the LMP charged to load — the congestion component — produces congestion revenues that the market collects and must allocate back to participants through settlement.

Under the EDAM design that FERC approved earlier, congestion revenue associated with a particular transmission constraint was allocated to the balancing area where that constraint is located. Protesters in the Pacificorp tariff filing argued that, when a constraint in a neighboring balancing area drives parallel flows and creates congestion exposure for transmission customers exercising firm point‑to‑point rights, the EDAM entity (for example, Pacificorp) might not receive sufficient congestion revenues to provide the congestion‑cost protection the tariffed rights are intended to provide.

\"We can determine how much of that was due to parallel flow versus an internal constraint,\" Milos Kosanec said, describing the ISO’s ability to disaggregate settlement impacts and the rationale for the proposal.

The targeted change proposed by ISO staff would leave the basic allocation rule in place (congestion revenues generally go to the balancing area where the constraint is located) but would reassign parallel‑flow congestion revenues — that is, congestion revenue tied to impacts of a constraint in another balancing area that affects prices in the EDAM entity’s footprint — back to the EDAM balancing area where the transmission customer exercised its rights. The ISO said the change is intended to ensure that transmission customers who exercise firm rights are not left undercompensated when cross‑area loop flows cause price separation.

ISO staff said they published a final proposal following workshops and written comments, plan to seek approval from the ISO’s governing bodies on June 19 (the Western Energy Markets governing body and the ISO board), and — if approved — would file the change at FERC by the end of June to support EDAM implementation timelines. The ISO said settlement systems are capable of tracking and apportioning congestion revenue disaggregation for settlement purposes, although that accounting is performed in settlement rather than shown in near‑real time.

Utah commissioners and staff asked technical questions about how congestion revenues are measured, how transfer revenue between balancing areas is shared (the ISO said transfer revenue from an inter‑BA scheduling limit is split 50/50), and whether the proposal reduces overall congestion revenue available to other balancing areas. ISO staff said the proposal reallocates only the portion tied to parallel‑flow impacts and will be monitored after implementation; staff also committed to reengage stakeholders and to evaluate additional enhancements as the footprint grows.

The ISO presenters on this topic were Milos Kosanec and Anna McKenna. Utah participants included staff from the Division of Public Utilities and members of the Utah Public Service Commission.","The California ISO proposed a targeted allocation change to ensure that congestion revenues tied to parallel flows are allocated to the balancing area where transmission customers exercise firm rights, a move officials said would preserve congestion‑cost protection for customers who use point‑to‑point transmission rights under EDAM.","actionData","errors"]
