Now in the electric car maker’s most recent earnings call this week, Tesla showed just how far along the company has actually come towards selling batteries for the power grid market. Tesla CEO Elon Musk said on the call that Tesla has already been “bidding on a lot of RFPs [request for proposals],” for utilities looking to build energy storage projects.
Utilities, particularly in California, have begun to look into building out big battery banks that can store energy and help them better manage their grids. Battery banks can help smooth out clean energy, which only provides power when the sun shines or the wind blows. For example, batteries built next to a solar farm could store the solar energy during the day to be used later at night.
