Get to know Base

What you need to know before signing up for Base with Austin Energy.

Hi there,

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,

How it works

Backup for your home. Support for the grid.

Austin Energy uses these home batteries to add capacity during peak demand. When the grid is down, your battery keeps your home powered.

When the grid is up and running.

Austin Energy can draw on the battery to add capacity during high demand hours, which helps reduce outage risk.

We've got answers

The — install is the Austin Energy customer price, with a — monthly membership. Austin Energy can draw on the battery to add capacity during high demand hours, which helps reduce outage risk.

When you need backup power, the battery is there for your home.

If you receive your monthly energy bill and service from Austin Energy, you will continue to do so with the installation of a Base Core.
No. Your energy provider does not change when you get a Base Core. If you see language about energy provider services on Base's website, this is because Base also serves customers in other service areas of Texas. If you live outside of Austin Energy's service area, your zip code will return plans here.
During an outage, the batteries automatically detect the loss of grid voltage and immediately disconnect your house from the grid. At that point, the battery supplies energy exclusively to your home — you are legally entitled to this energy, and our batteries will never discharge to the grid during an outage. Once the outage is over, your battery seamlessly reconnects your house to the grid and resumes normal operation.
No. You will only be billed for energy that your home consumes, just like you were before your Base Core was installed. Energy consumed by your property is still measured in full by your meter, and your monthly bill is calculated the same way as before. Your battery sits in front of your electric meter, rather than behind it like most residential storage systems. Therefore, any battery activity will not impact your home since it does not pass through the utility billing meter. Base advises members to reach out to Austin Energy Customer Service directly at 512-494-9400 with specific questions related to energy bills.
The — deposit reserves your spot with Base Power. If the member decides to continue with Base after paying the deposit, that amount will be applied toward the upfront installation cost. If an Austin Energy customer chooses not to move forward with Base after approval, or if their home does not qualify for the program, the deposit will be refunded in full.
Members are not responsible for any battery activity that their home did not use. Batteries must recharge in order to stay operational. The battery can only backup your home if it continuously recharges from the electric grid.
Yes. The battery automatically covers most outages. For longer ones, you can plug a typical portable generator into Base's generator port to keep the battery charged — no transfer switch required.
