Wisconsin-based Alliant Energy customers with batteries can earn up to $1,500 in enrollment incentives, plus ongoing payments, by helping strengthen the electric grid

SAN JOSE, Calif., Oct. 20, 2026 /PRNewswire/ — FranklinWH Energy Storage Inc. today announced that Alliant Energy customers in Wisconsin with FranklinWH Systems, are able to participate in Alliant Energy^® Smart Hours, a residential battery program that rewards homeowners for supporting grid reliability while earning financial incentives.

Through the program, Alliant Energy customers receive an enrollment incentive of $100 per kilowatt-hour of battery capacity, up to $1,500 for a FranklinWH System. Participants also earn annual performance payments of $100 for every average kilowatt their system discharges when called upon to support the grid.

Once enrolled, the FranklinWH System automatically sends stored battery energy to the grid during periods of peak electricity demand. Homeowners don’t need to take any action during an event and can set how much stored energy they make available, so they keep an appropriate level of backup power for their home.

FranklinWH has partnered with energy technology company Derapi to streamline enrollment, helping FranklinWH systems connect to Smart Hours.

“Wisconsin homeowners already rely on their FranklinWH System to keep the lights on during outages,” said FranklinWH chief commercial officer, Vincent Ambrose. “Now they can put that same battery to work supporting the electric grid while earning financial incentives. Programs such as Smart Hours show how families can play an active role in building a more reliable grid.”

Alliant Energy’s planned and operational battery projects in Wisconsin total 275 megawatts. By enrolling in Smart Hours, residential battery systems further expand this capacity, offering the utility greater flexibility to meet rising energy demand.

The Smart Hours program adds another utility partnership to FranklinWH’s growing presence across the country. FranklinWH now participates in more than 30 VPPs.
