FAQs about Columbia Mobile Energy Storage Container 15MWh

What is the Columbia Energy Storage Project?

Sign up for WPR's email newsletter. The Columbia Energy Storage Project would store excess energy from the electric grid by converting carbon dioxide gas into a compressed liquid form and then converting that liquid back into a gas, powering a turbine to generate electricity, according to the Department of Energy.

Is a new energy storage system coming to Wisconsin?

Photo courtesy of Alliant Energy A first of its kind energy storage system coming to Wisconsin took a step forward this month, almost a year after the project was announced. Alliant Energy filed an application with the state Public Service Commission on Aug. 7 to build a long-duration energy storage system in Columbia County.

Who owns Columbia County's coal-fired power plant?

Columbia County is currently home to a coal-fired power plant owned and operated by Alliant Energy, with partial co-ownership from WEC Energy Group — parent company of Wisconsin Public Service and We Energies — and Madison Gas and Electric. That plant is slated to come offline by mid-2026.

Why is mobile energy storage a stranded asset?

Stationary storage lacks flexibility, suffers from low utilization and from the risk of becoming a stranded asset. Power Edison addressed these issues by developing mobile energy storage platforms: TerraCharge™ and AquaCharge™ for mobile land-based and water-based mobile energy storage respectively.
