Electric Power Research Institute (EPRI) is leading a net-zero energy home pilot project in Fontana, California and has chosen SunEdison to supply battery systems form the nine eco-houses to be built. The project is supported by the California Public Utilities Commission, national homebuilder Meritage Homes, and Southern California Edison.

Objective of the project

The research institute is leading the project to evaluate how net-zero energy homes that generate and store their own energy impact the local electricity grid. This project is important for future grid planning because under the California Public Utilities Commission's Energy Efficiency Strategic Plan, California aims to have all new homes be net-zero starting in 2020, and all new commercial buildings by 2030.

"With this project, we're pioneering solutions that will help Californians prepare for the future of the grid, where homes and businesses will be generating their own electricity on a much greater scale than we're seeing today," said Tim Derrick, SunEdison's general manager of Advanced Solutions. "By installing SunEdison's battery systems on these net-zero energy homes, we're able to store solar-generated electricity and better manage the interactions of that electricity with the grid."

SunEdison designed the advanced battery system, and partnered with Eguana Tech, LG Chem and Geli for this project, and will monitor and control the system to optimize the energy savings and load profile. Meritage Homes has already started construction on the homes and expects to complete the first homes by the end of September.

Ram Narayanamurthy, EPRI's project lead, said, "We're using advanced controls and energy storage to manage these mini, distributed power plants that are expected to play a much larger role in the grid of the future."
