Texas utility regulators have shifted management of the aggregated distributed energy resource, or ADER, pilot program into the Electric Reliability Council of Texas stakeholder process in order for the burgeoning resource to “engage with a larger community of ERCOT market participants,” according to a staff memo recommending the change.
ADER launched more than two years ago, with the Public Utility Commission of Texas organizing the governing task force. “I’m comfortable with this moving to ERCOT now that we’re looking at more technical aspects,” PUCT Chairman Thomas Gleeson said at the commission’s Thursday open meeting.
The ADER pilot has yet to hit its phase one capacity targets, but as of February there were three virtual power plants providing 25.5 MW of energy and almost 20 MW of other reserve services, according to staff’s memo. The program launched in 2022 with a goal to harness 80 MW of flexible resources, but experts say initial limits on the program’s size dissuaded participation.
Commissioner Kathleen Jackson said shifting the program to ERCOT is “the logical next step.”
PUCT staff will continue to monitor the project and recommended that ERCOT report progress on the pilot every six months.
Former Commissioner Jimmy Glotfelty led the ADER effort from the commission, working as a liaison to the task force which developed the initial rules for the pilot with the grid operator. Glotfelty retired from the PUCT last year but told Utility Dive “success, to me, is if in three years, or two years, [ADER has] 300 MW or 500 MW and it’s a general part of the market system.”
Virtual power plants, deployed at scale, can reduce the need for long-term power system investments and are being considered across the U.S., experts say. A 60-GW nationwide deployment could help meet the country’s future resource adequacy needs while avoiding $15 to $35 billion in infrastructure costs over the next 10 years, according to a 2023 Brattle Group report.
