Long duration liquid air energy storage system proposed for Vermont

Highview Power Storage and Encore Renewable Energy on Dec. 18 announced plans to develop what they said will be the first long duration liquid air energy storage system in the U.S.

The size of the facility, which will be located in northern Vermont, will be a minimum of 50 megawatts and provide in excess of eight hours of storage (400 megawatt hours).

The project is the first of many utility-scale, liquid air energy storage projects that Highview Power plans to develop across the U.S. to help scale up renewable energy deployment.

The companies said that the Vermont facility will contribute to resolving the longstanding energy transmission challenges surrounding the state’s Sheffield-Highgate Export Interface and enable the efficient transport of excess power from renewable energy resources to help integrate them on the power grid.

Highview Power Storage and Encore Renewable Energy said that other services the facility will be able deliver include market arbitrage, frequency management, reserve, and grid constraint management services.

The companies are in discussions with potential utility and transmission grid operator customers regarding the capabilities and services the facility can provide.

Encore Renewable Energy is a Vermont-based company that specializes in the development, financing, permitting, construction management and O&M of renewable energy projects.
