Construction has started on the Chisholm Grid battery energy storage system, the largest standalone battery energy storage project currently under construction outside of California in the US.
Chisholm Grid, based in Fort Worth, Texas, will have an initial rated capacity of 100 megawatts (MWac) and is expected to start commercial operations by mid-2021.
The Chisholm Grid battery energy storage system was built by Able Grid Infrastructure Holdings, a joint venture between Able Grid and MAP.
Able Grid will provide on-site construction management services and operational asset management services. Astral Electricity, a privately owned energy storage power provider, owns Chisholm Grid.
Astral gave complete notice to proceed to Mortenson in early August and work has already begun on site to align plant and high-voltage transmission components, making Chisholm Grid the largest stand-alone battery energy storage project currently under construction outside California in the United States.
At peak construction approximately 50 workers will be working on-site at Chisholm Grid, and Mortenson has negotiated subcontracts from local trade partners based in Dallas–Fort Worth to ensure local involvement in the project.
