The Austin Energy home battery rebate pays 500 dollars upfront and more than 300 dollars a year, but only 165 batteries have enrolled toward a 1,500 system cap

Austin Energy, the city owned utility, caps the Power Partner Battery Pilot at 1,500 approved home battery systems in its first year. As of June 2026, about 165 batteries across just over 100 customers had signed up, even as the utility counts on this and similar programs to reach 78 megawatts of demand response capacity by 2027 and 270 megawatts by 2035.

The Austin Energy home battery rebate pays 500 dollars upfront

Austin Energy, the city owned utility that serves the Texas capital, runs a home battery rebate called the Power Partner Battery Pilot, paying an enrolled residential customer 500 dollars upfront for an eligible home battery, plus an additional average of more than 300 dollars a year for letting the utility draw stored power from that battery during periods of high electricity demand. The annual payment follows a formula, 75 dollars per kilowatt each year, based on the size of the battery, the reserve level the customer sets, and the average number of hours the battery took part in a demand response event, a scheduled window in which the utility calls on customer batteries instead of running extra power plants.

Which batteries qualify and what enrolling requires

The battery must have received permission to operate after February 18, 2025 to qualify for the 500 dollar rebate, and there is no limit on how many battery systems one customer can enroll. The utility keeps a live enrollment page online that lists 5 eligible battery brands, Tesla, FranklinWH, SolarEdge, Enphase and Generac. The March 2026 launch announcement and both independent news accounts of it named only the first 4 brands, so a reader checking only that early coverage would miss that Generac equipment now qualifies too, a change visible only on the operating page itself.

During a call event, which can happen on any day including weekends and holidays, the battery must keep at least a fifth of its stored charge in reserve rather than being drawn down further. Austin Energy can call up to 40 of these events a year, not counting grid emergencies, and each typically lasts 2 to 3 hours.

Enrollment is far behind the pilot cap

The pilot caps enrollment at 1,500 approved battery systems in its first year. As of June 2026, more than 100 customers had enrolled about 165 batteries toward that cap, according to Hoodline, leaving most of the year one capacity still open to a new applicant. About 11% of that year one cap was filled by June 2026, a figure calculated by dividing the 165 batteries enrolled into the 1,500 system cap, not a percentage either source states directly.

Remaining capacity is calculated for this article, the 1,500 system cap stated in sources 1, 3 and 4 minus the 165 batteries Hoodline reports as enrolled by June 2026, source 5. Neither source states the remaining figure directly.

This pilot is one piece of a bigger demand response target

Austin Energy already delivers 57 megawatts of flexible capacity through its existing demand response programs, which call on customer thermostats and electric vehicle chargers as well as batteries. The utility is targeting 78 megawatts by 2027 and 270 megawatts by 2035, under its Resource, Generation and Climate Protection Plan. Those 2 targets describe the whole demand response program, not the battery pilot by itself, since no source states a battery only megawatt goal for this specific pilot.
