Powin Energy has secured a contract to provide San Diego Gas & Electric (SDG&E) with a 6.5MW/26 MWh battery energy storage system in California, US.
The battery energy storage system will be installed at the orange processing facility in Escondido of California, subject to approval from the California Public Utilities Commission (CPUC).
It will be integrated with the electrical grid and improve electricity reliability. The project help revitalize the surrounding community through infill development.
Powin Energy said its Stack140 system will optimise the output from renewable sources with grid demand that doesn’t always coincide with the intermittent production of distributed resources.
The Stack140 modular battery system includes patented Battery Pack Operating System (bp-OS), which offers critical insight into system functions and lifespan through the battery odometer and warranty tracker.
Stack140 is a modular and 140kWh battery array, which can scale from 125kW to multiple megawatt applications
Powin Energy president Geoffrey Brown said: "I appreciate the confidence SDG&E has shown in Powin Energy by selecting us for this important project.
“We continue to find that utilities and IPPs see tremendous value in the fact we do our own engineering, software development, and manufacturing. It makes it easy for us to be adaptable to a given project's unique requirements rather than offering one-size-fits-all solutions.”
The CPUC has suggested SDG&E to install 165MW of energy storage by 2020, which are required to be fully operational by 2024.
According to the Department of Energy's Energy Storage Database, the SDG&E has around 94MW of deployed or contracted storage across 20 projects.
