We started Base because we thought there was a better way to do home backup. We install a battery at your home that gives you up to 36 hours of backup with reduced energy use. When the grid is up, Austin Energy can use the battery to help meet demand. That's what makes backup this affordable.
As an Austin Energy customer, you can get Base Core installed for — with a — monthly membership. You keep your existing energy service and bill, while Base gives your home whole-home backup when the grid goes down.
We know Base works a little differently, so we put together everything you need to know below.
Stay powered,
