EPRI leads project for net-zero homes using SunEdison battery systems

The Electric Power Research Institute (EPRI), a non-profit organisation funded by electric utilities to conduct research on issues related to the electric power industry in USA, is leading a project that will see renewable energy development company SunEdison supply battery systems for nine net-zero energy homes in California.

Net-zero energy homes are able to generate and store their own energy and EPRI is investigating what impact these homes, located in Fontana, will have on local electricity grids.

PV Tech Storage reported last year that EPRI, in partnership with utility holding company Southern Company, would be testing and evaluating a 1MW/2MWh lithium-ion battery-based storage system paired with a 1MW solar array in Cedartown, Georgia. That new research project was officially opened today.

For the net-zero homes in Fontana, SunEdison designed the advanced battery systems and will monitor and control them to maximise energy savings and optimise load profile, thus preventing networks from becoming imbalanced.

Other major PV developers have also conducted trials on zero energy homes or offered them as commercial propositions, such as the ‘double zero energy’ home with energy storage and solar PV systems launched in the US last year by a partnership between SunPower and homebuilder KB Home.

For the California project, SunEdison also partnered with Eguana Tech, a supplier of inverters for distributed smart grids and micro-grids, and battery provider LG Chem. It also worked alongside Geli, which provides software for the connection and operation of energy storage and micro-grid systems. Geli’s interface can monitor a storage system’s performance and aggregate systems for virtual power-plant services.
