Temporary generators now online in Roseville

Updated September 29, 2021

Two temporary mobile generators are now online in Roseville following six weeks of construction at Roseville Energy Park.

The two generators were deployed by the Department of Water Resources (DWR) following an emergency proclamation by the governor in July. Each unit can produce up to 30 MW of power, totaling 60 MW of power. The units run on natural gas but can run on a blend of up to 75 percent hydrogen.

The generators would be deployed under emergency conditions determined by the California Independent System Operator (ISO) under a contingency plan developed in coordination with the CEC and the California Public Utilities Commission.

To raise awareness in the communities surrounding these generators, the CAISO has posted a document outlining an order from the US Department of Energy as well as the circumstances under which the CAISO can activate the units.
