Austin, TX
Home battery backup for Austin homeowners
Austin sits at the intersection of Austin Energy, Pedernales Electric Cooperative, and the broader ERCOT grid. The 2021 winter storm and the 2023 ice storm both produced multi-day outages here. Eos installs automatic battery systems that take over the moment the grid drops, regardless of which utility serves your address.
Why Austin is buying batteries
Austin homeowners experienced one of the most public ERCOT grid failures in recent memory during the February 2021 winter storm. Rolling outages stretched into multi-day blackouts, water systems failed, and homes with no backup heat or power had no fallback. The 2023 ice storm produced a similar pattern at smaller scale, with extensive tree damage and multi-day power loss across central and west Austin.
Battery adoption has accelerated since. Austin homes commonly land in the Pro or Premium tier, which provides enough capacity to ride out a multi-day event with essentials and some climate control. Larger homes in west Austin and the Hill Country suburbs (Lakeway, Bee Cave, Dripping Springs) often go for the Ultimate tier with full-home backup.
For homes already on solar, we add battery storage to capture solar production during the day and use it overnight or during outages. Austin Energy has well-established interconnection rules for solar+battery, which we handle on your behalf.

Common questions from Austin homeowners
Which utility serves Austin homes?
Inside Austin city limits, Austin Energy is the municipally-owned electric utility. Suburbs like Lakeway, Bee Cave, and parts of Dripping Springs are served by Pedernales Electric Cooperative (PEC). North Austin and Williamson County areas may also fall under Oncor or other co-ops. Our team confirms which utility serves your address and submits the correct interconnection paperwork.
Did the 2021 Winter Storm Uri affect Austin?
Significantly. Austin was one of the hardest-hit metros during Uri in February 2021, with rolling outages and cold snaps that left some neighborhoods without power for 4 to 6 days. The 2023 ice storm also brought widespread tree-related outages across central and west Austin. Battery interest in Austin has stayed strong since.
How long is the lead time for an Austin installation?
Outside the Greater Houston metro, scheduling is slightly longer than our typical 1 to 2 week window. Austin installations typically run 4 to 6 weeks total from first contact to a working system, including permit processing through City of Austin Development Services and utility coordination.
Does Austin Energy support battery interconnection?
Yes. Austin Energy has a defined interconnection process for residential battery storage, including backup-only configurations and solar+battery installs. We submit the standard interconnection notification on your behalf and coordinate any utility-side work required.
