Primus Power is deploying a 25 MW/75 MWh EnergyFarm™ in the Modesto Irrigation District substation in California that consists of a series of EnergyPods™; a plug-and -play zinc-flow battery combined with off-the-shelf components and power electronics housed inside a standard shipping container. The modular design and operation will be field tested at Pacific Gas & Electric with support from Sandia National Lab and the Electric Power Research Institute. The EnergyFarm™ will displace a planned $78M fossil fuel plant. EnergyFarms™ can firm intermittent wind energy and mitigate energy price spikes. During a spike the Farm switches to full dispatch power, reducing energy purchases during costly periods, capturing multiple revenue streams, and shortening return on investment. EnergyFarms™ are scalable from 330 kW/1 MWh up to systems larger than 100 MW/300 MWh.
