Apple Inc (NASDAQ: AAPL ) said on Wednesday it will build a battery-based renewable energy storage facility in central California, near a solar power plant that already provides electricity to all of its facilities in California. the state.

Apple said the project will store 240 megawatt-hours of energy, or enough power to power more than 7,000 homes for one day. It is located next to the California Flats solar plant in Monterey County, about 100 miles southeast of the company’s headquarters in Cupertino, California.

The site sends 130 megawatts of electricity directly to Apple’s California facility during daylight hours, but provides no power at night.

Lisa Jackson, Apple’s vice president of environment, policy and social initiatives, told Reuters in an interview that the company is looking to develop what it believes will be one of the largest battery-based storage systems in the United States.

“The challenge with clean energy – solar and wind – is that by definition they are intermittent,” Jackson told Reuters. “If we can do it, and we can show that it works for us, it removes intermittent concerns and helps the network in terms of stabilization. It’s something that can be replicated or built on by other companies.”

Jackson said Apple plans to share its findings from the project with other companies, but said it’s too early to say precisely how it would do so.

Apple has other projects where it has shared environmental technology advances, including an aluminum smelting joint venture in Canada and an Apple technology recycling lab in Texas.

The company also said Wednesday that 110 of its suppliers are starting to use clean energy for the work they do for Apple, with an expected output of about 8 gigawatts of clean energy as a result, or what Apple said is the equivalent of retiring 3.4 million cars from the streets.

The figure is an increase from last year, when Apple said 70 of its suppliers had transitioned to clean energy for their work with the company, which has set a goal of eliminating carbon emissions from its supply chain by 2030. .
