Wisconsin’s first large-scale battery energy storage system (BESS) project, the 110MW Paris Solar-Battery Park, has come online.

Wisconsin, US utility Madison Gas and Electric (MGE) is partnering with We Energies and Wisconsin Public Service (WPS) to purchase 30MW of solar capacity and 16.5MW of battery storage from the High Noon Solar Energy Centre.

Three utilities in Wisconsin are seeking regulatory approval to acquire two solar and storage hybrid projects from Blackstone portfolio company Invenergy as part of a wider US$1.92 billion investment.

IPP Invenergy has put a 50MW BESS into commercial operations in Arizona, US, its 10th in the state.

The US Department of the Interior’s Bureau of Land Management (BLM) has progressed nine hybrid solar and storage facilities located across the states of Nevada and Arizona.

Madison Gas and Electric has purchased a solar and battery storage plant with combined capacity of 465MW with WEC Energy Group.

Wisconsin’s Public Service Commission has approved Invenergy 300MW solar farm, to be paired with a 165MW battery energy storage system.

Renewable Energy Systems ranks alongside US firm AES at the top of a new leader-board of energy storage systems integrators; its two new National Grid contracts will see it top the table, it says.
