We’ve been delivering safe, affordable, reliable electricity for well over a century.
Representing a mix of ethnic backgrounds, generational ties, gender, and life experiences, our leadership team offers a broad array of perspectives and strategic insights.
Climate change and air pollution are serious threats that require the transformation of the way energy is produced and used. Here’s our proposal to do just that.
Today's energy customers are increasingly seeking choice in how they manage their energy. Utilities will evolve to become facilitators of customer choice and the clean energy economy.
The Clean Energy Access Working Group was launched through a groundbreaking partnership to help ensure no community is left behind as we move toward a clean energy future.
At San Onofre, the long and complex decommissioning process will be guided by three core principles.
Meeting California's ambitious greenhouse gas emission reduction goals will require a significant electrification of homes and other buildings.
As fuel for transportation, electricity makes sense.
We're modernizing the grid to support California's transition to a clean and sustainable future.
We're developing and implementing cutting-edge cybersecurity technologies to secure the electricity grid and protect customer data.
We are using battery energy storage to help create a cleaner, more resilient grid.
Our utility, Southern California Edison, is working to incorporate more clean energy into the grid every day.
We're examining whether renewable energy and other cleaner sources can help lessen the need for new power plants in California.
We're making a difference in the community by partnering with local nonprofits that have programs focused on education, the environment, public safety & emergency preparedness, and civic engagement.
Edison Scholars awards $40,000 scholarships to students who want to make a difference in the world.
Our employees are known for their volunteerism, from cleaning beaches to feeding the homeless.
Sustainability is elemental to our vision of a safer, more dependable, and cleaner energy future.
Our teams are diverse and inclusive, and we count on everyone to bring something to the table.
Working here means being part of a collaborative, diverse, and dynamic workplace culture.
It all starts with searching our job listings, and completing an online application.
The Mira Loma Battery Storage Project can store up to 20 megawatts, enough energy to power 15,000 homes for four hours.
Batteries allow us to capture and store energy during times of low demand, when it is plentiful and inexpensive, and use it during times of high demand, when energy is in short supply and more expensive.
As more and more renewable resources such as solar and wind come online, batteries can help smooth out the fluctuations in these resources by storing the energy they generate and supplying it to the grid later when the sun isn’t shining or the wind isn’t blowing. Energy storage can also support local distribution circuits impacted by the high penetration of renewable resources and improve power quality.
Over time, greater reliance on energy storage could offset traditional ways of meeting increased energy demand, such as building new power generation stations.
At the beginning of 2017, Southern California Edison had nearly 400 megawatts of energy storage under contract. That’s almost double the amount that was installed in the entire nation in 2015. These resources include:
SCE entered into contracts for 67 megawatts of battery energy storage to increase grid reliability and to help mitigate the impacts of the projected gas shortages from the 2015 leak and subsequent shutdown of SoCal Gas’ Aliso Canyon Natural Gas Storage Facility.

SCE Unveils World’s First Low-Emission Hybrid Battery Storage, Gas Turbine Peaker System
The 125 megawatts of power purchased for the Preferred Resources Pilot (PRP) include 75 megawatts of battery energy storage. PRP is a multiyear project designed to determine whether “preferred resources”—including solar, wind, energy storage, energy efficiency and energy conservation—can be used to offset the increasing demand for electricity in Orange County.

SCE purchased 260 megawatts of power from battery energy storage providers in 2014 as part of a 2200-megawatt procurement designed to meet local reliability needs for the L.A. Basin. Because energy storage was cost-competitive when compared with other preferred resources, the size of the battery energy storage component was more than five times the amount that the state required – a widely recognized game changer for the storage industry.

When it was commissioned in 2014, the Tehachapi Energy Storage Project demonstration was the largest lithium-ion battery energy storage demonstration project in North America. The facility is located near one of the largest wind generation hubs in the U.S. — the Tehachapi Wind Resource Area. It is capable of supplying 32 megawatt-hours of electricity — eight megawatts of power for four continuous hours, which is enough to power 6,000 homes. With the demonstration concluded, the facility is online as a distribution-level resource supporting SCE’s Monolith substation near Tehachapi, CA.
The Irvine Smart Grid demonstration project, which was conducted in a residential neighborhood on the University of California at Irvine campus, was an end-to-end study of smart grid technologies with multiple energy storage systems. A “smart grid” is an increasingly intelligent and highly automated electric power system that incorporates technological advances in power system hardware, telecommunications, computing and more. The purpose of the project was to examine how to support the increasing contribution of renewable resources to the power system, the changing demands on the system, and how to respond to real-world concerns. The demonstration was co-funded by a U.S. Department of Energy grant.
This battery energy storage system in Orange is SCE’s first pilot system deployed to support its distribution grid. DESI I’s primary purpose is to help industrial customers with reliability, especially during the hottest months when there is an increased demand for electricity. The system is capable of supplying 2.4 megawatts of power continuously for about an hour and a half.
Our utility, Southern California Edison, collaborates with many organizations to support innovation in the areas of renewable sources of energy, grid optimization, and energy storage. If you are working on a project of this nature and need a letter of support or commitment for a California Energy Commission EPIC proposal, DOE or other funding source proposal, we may be able to help.
