Apple said the project will store 240 megawatt-hours of
energy, or enough to power more than 7,000 homes for one day. It is located
next to the California Flats solar installation in southeastern Monterey
County, about 100 miles southeast of Apple's Cupertino, California
headquarters.
The site sends 130-megawatts of electricity directly to
Apple's California facilities during daylight hours but does not provide power
during dark hours. Lisa Jackson, Apple's vice president of environment, policy
and social initiatives, told Reuters in an interview the company intends 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 it's by definition intermittent," Jackson told Reuters. "If we
can do it, and we can show that it works for us, it takes away the concerns about
intermittency and it helps the grid in terms of stabilization. It's something
that can be imitated or built upon by other companies."
News portal Verge reported, citing Monterey County's
planning chief, that Apple will receive the battery packs for this facility
from electric-car maker Tesla Inc.
Its setup will consist of 85 Tesla lithium-ion
"megapacks," the report added. Monterey County officials, Apple and
Tesla did not immediately respond to Reuters' requests outside regular business
hours.
Jackson said Apple plans to share its findings from building
the project with other companies, but said it was too early to say precisely
how it would do so. Apple has other projects where it has shared environmental
technology developments, including an aluminum smelting joint venture in Canada
and an Apple recycling technology lab in Texas.
Apple on Wednesday also said that 110 of its suppliers are
now moving to using clean energy for the work they do for Apple, with about 8
gigawatts of clean energy production planned as a result, or what Apple said
was the equivalent of removing 3.4 million cars from the road. The figure is an
increase from last year when Apple said 70 of its suppliers had made the
transition to clean energy for Apple work when it set a goal to eliminate
carbon emissions from its supply chain by 2030.
