In November 2009 Primus Power was one of sixteen companies selected by the Department of Energy (DOE) to receive a Smart Grid Demonstration Program grant. Our $14M award is part of an overall $47M project to commercialize, deploy and monitor a 25 MW • 75 MWh energy storage system to a California utility where it will firm intermittent wind energy.

In July 2010 we received an ARPA-E grant as part of the Grid-Scale Rampable Intermittent Dispatchable Storage program.
