Project Overview

The 300 MW / 600 MWh Larkspur Energy Storage facility will provide energy and capacity services to the ERCOT grid, enhancing grid reliability and accelerating the integration of locally produced renewable energy. The project will abide by the most stringent design and cutting-edge safety standards to ensure the project maximizes benefits to ERCOT and Upton County.

Construction of the Larkspur facility is anticipated to start in 2025. The 2026 completion of the facility will help grid operators combat the effects of more frequent extreme weather events by increasing capacity and reliability on the grid and in the region.

Situated along a major transmission corridor and directly abutting the Benedum substation, the site’s location minimizes environmental impacts. Larkspur’s site location is optimal for new energy infrastructure as it does not require long transmission lines to connect the facility to the power grid and is conducive to surrounding land uses.
