Sandia National Laboratories has selected the Edison Electric Institute (EEI) to lead a forum of the National Consortium for the Advancement of Long Duration Energy Storage Technologies, handing the trade group — which represents all U.S. investor-owned utilities — a central coordination role in a Department of Energy-funded effort launched in 2023.

The consortium's remit is explicit: accelerate commercialization of long-duration energy storage (LDES) technologies within a decade. Sandia formed the group in 2023 together with five partner national laboratories, and it now unites more than 200 industry, academic, and government stakeholders — 215 teaming partners, by the count of Will McNamara, the consortium's principal investigator at Sandia.

"EEI is honored to lead the LDES National Consortium, and we thank the U.S. Department of Energy, Sandia National Laboratories, and the other national laboratories for this opportunity," EEI President and CEO Drew Maloney said Wednesday.

"As electricity demand accelerates, long-duration energy storage can help make the electric system more flexible, reliable, and affordable," Maloney said. "In this new leadership role, we look forward to continuing our work to bring stakeholders together and advance this critical technology."

In the forum leadership role, EEI said it will convene LDES stakeholders — industry leaders, technical experts, national laboratories, government partners, investors, regulators, and technology developers — to identify deployment barriers, develop solutions, and speed commercialization.

What the consortium claims, and what to weigh

EEI frames the commercial case in system terms: proven LDES technologies, it argues, can improve reliability and resilience, reduce supply costs during high-price periods, and optimize infrastructure investment by making better use of the existing grid as electricity demand grows and the supply mix shifts. These are projections, not measured results, and the consortium's decade-long commercialization timeline will test them against actual project economics and technology performance.

The appointment rewards incumbency. EEI was an original teaming partner, active since the consortium's inception, contributing to working groups focused on specific commercialization and deployment challenges. It also helped establish a multi-year collaboration with the Electric Power Research Institute, the Long Duration Energy Storage Council, and DOE to accelerate LDES commercialization.

McNamara credits the consortium's first three years to the breadth of its membership. "Over the past three years, the success of the LDES National Consortium has been driven by the active collaboration of our 215 teaming partners, including EEI," he said. "We are excited and confident that EEI will provide exceptional leadership for the consortium."

For R&D managers tracking storage portfolios, the move signals where DOE's national lab system sees the commercialization bottleneck: not in single-technology breakthroughs but in coordinating utilities, regulators, investors, and developers around deployment barriers. EEI's membership base gives technology developers a single industry interface, though it also concentrates forum leadership in the organization representing the utilities that would buy — or compete with — storage deployments.

The consortium has not disclosed specific funding figures tied to EEI's forum leadership. The initiative remains DOE-funded under Sandia's management, with its stated ten-year commercialization clock running since 2023.

EEI says it will continue convening stakeholders to identify barriers and accelerate deployment, with consortium leadership now betting that utility-sector coordination can move LDES from pilot-stage technologies to bankable grid assets inside the decade.
