Tempe-based First Solar Inc. will build a large solar plant in the West Valley that will use a massive battery to deliver power to Arizona Public Service Co., the companies said Monday.
The project will be unique not only for the size of the battery being put to use, but for the way the plant is operated, officials said. APS recently has placed other batteries on the grid, but they are much smaller than what will come with the solar plant.
