Southern California Edison (SCE) and Swell Energy have partnered to launch a home battery program to help homeowners protect their power and strengthen the grid as Californians become accustomed to the new reality of public safety power shutoffs (PSPS).
Home batteries are especially effective when combined with rooftop solar, allowing the home to recharge itself indefinitely.
“Solar and storage can be an incredibly powerful technology combination for a homeowner who is looking to protect their power from service interruptions, planned or unplanned,” said Suleman Khan, CEO of Swell Energy. “And in the bigger picture, grid operators can tap into the distributed power of a networked system of residential solar+storage installations to make the entire region more resilient and secure.”
To incentivize home energy storage, SCE has partnered with Swell Energy to offer a limited number of rebates for qualified Orange County homes for the installation of a Tesla Powerwall 2. Up to 1,500 qualified SCE customers will receive the $5,200 rebate. This rebate can be combined with the state-provided Self Generation Incentive Program (SGIP) and 30% Federal Investment Tax Credit (ITC) to substantially reduce the investment cost to the homeowner.
The home battery program is a part of SCE’s second Preferred Resources Pilot (PRP 2), a diverse portfolio of resources which will work together to strengthen the electrical grid, including energy efficiency, demand response, energy storage and distributed generation. The PRP 2 was developed to test the ability of distributed energy resources (DERs) to serve as a solution to grid instability caused by the closing of the San Onofre Nuclear Generating Station. SCE has commissioned Swell to build an interconnected, dispatchable fleet of 3,000 residential energy storage systems that will be able to provide up to 20 MWh of reduced demand, on demand.
Grid operators are increasingly turning to DERs as a solution to real-time imbalances in electricity supply and demand. Using cutting edge technology, utilities can reduce the risk of fires caused by long distance transmission of energy, and reduce the need for precautionary planned outages due to weather conditions such as high winds.
“I installed solar and storage in my home because it’s important to me to know that my family will have power in an emergency situation. And the rebates and incentives made it quite affordable to do so,” said Sir R., an Irvine customer. “But I also take pride in knowing that my solar and storage system is part of this greater program to strengthen the electricity grid, prevent fires, and reduce our reliance on fossil fuels.”
