August 2025 storms and flooding
We Energies crews restored power to more than 150,000 customers after the August 2025 storms, working 16-hour shifts alongside hundreds of mutual-assistance lineworkers while facing historic flooding.
Rg1: 19.342¢ plus a daily charge
The standard residential rate (Rg1, effective January 1, 2026) charges $0.49315 a day and 19.342¢ per kWh, plus a fuel cost adjustment of 0.199¢ and an environmental control charge of 0.052¢ per kWh.
Rg2: pick your 12-hour peak
The Rg2 time-of-use rate prices on-peak energy at 30.084¢ and off-peak at 10.028¢. You choose a 12-hour weekday on-peak window: 7 a.m.–7 p.m., 8 a.m.–8 p.m., 9 a.m.–9 p.m. or 10 a.m.–10 p.m.; holidays are off-peak.
Where a battery fits in Milwaukee
Flood-season backup, the sump pump and time-of-use.
Keep the sump pump running
When storms flood basements, an outage at the same time stops the sump pump. A battery on a critical load panel keeps the pump, refrigeration and internet on while crews restore power.
Size for the pump's start-up
Sump pumps draw a surge when they start. That surge, not just running watts, decides what battery and inverter can carry the circuit.
Shifting a 12-hour peak
Rg2's on-peak window is long, so a battery covers only part of it. The value comes from the gap between 30.084¢ on-peak and 10.028¢ off-peak on the hours you shift.
Pick circuits, not the whole house
Central air, electric dryers and ranges drain a battery fast. Sizing starts from the circuits you need on during an outage.
Milwaukee next to Grand Rapids and Lansing
Across Lake Michigan, Grand Rapids sits on Consumers Energy, with a 2–7 p.m. summer weekday peak and Michigan's automatic outage credits.
Lansing is served by the city-owned Board of Water & Light, where a May 2025 storm left about 24,000 customers without power.

What a home battery job with us covers
Installation of storage and the backup circuits behind it, with the siting and utility paperwork handled.
Battery installation
Wall or floor-mounted storage installed to the listing and to the residential code sections that govern where it may go.
Backup and critical load panel
Deciding and wiring which circuits stay live, and which must never be on backup — the choice that defines what an outage feels like.
Integration with existing PV solar
Connecting storage to an array that is already on the roof, including whether the existing inverter supports it.
Transfer switch and disconnection
The equipment that separates the house from the grid during an outage, which is what makes backup legal as well as possible.
Siting to code
Location, clearances, separation and impact protection assessed against the adopted code before anything is mounted.
Permit, inspection and utility approval
The electrical permit, the inspection, and the utility's own approval step where storage touches the service.
This is installation work. No runtime, capacity or incentive figure is quoted before your loads and your utility are confirmed. Coverage is confirmed per service area rather than promised as blanket availability.
What the work actually looks like
A battery job is an electrical job. The panel, the circuits and the disconnection are most of it.

Can a battery run my sump pump in an outage?+
Yes, if the pump is on a circuit the battery backs up and the battery and inverter can handle its start-up surge. We check the pump and the panel before sizing.
How long will a battery run my house?+
It depends on capacity and which circuits you put on it, so we don't quote a runtime before seeing the panel.
Who installs it, and who is responsible afterwards?+
Seamless Home is the licensed contractor of record on the work it runs. Installation is performed by vetted installing partners engaged as our subcontractors, so the permit, the inspection and any correction notice carry one name.
