Tesla unveiled a new 13MW solar farm on the Hawaiian island of Kauai Wednesday, bringing the state closer to its ambitious goal of sourcing 100 percent renewables by 2045.

The farm includes nearly 300 Tesla Powerpack batteries, which provide 52 MWh of capacity and will allow the farm to sell stored power during the evening. The company estimated that the farm will offset 1.6 million gallons of fossil fuel usage per year in the state, which relies heavily on oil-fired power plants and has some of the highest electric rates in the country.

According to The Verge:

It's the first major solar-plus-storage project for Tesla since its $2.6 billion acquisition of SolarCity last year, and Tesla said in a statement that it "will work with energy providers around the world seeking to overcome barriers in the way of building a sustainable, renewable energy grid of their own."

Stationary storage is "something I think will probably be as big as the car business long term," Tesla CEO Elon Musk said during a tour of the Gigafactory last year. "And will actually have a growth rate probably several times that of what the car business is per year. The growth in stationary storage is really under appreciated. That's a super-exponential growth rate."
