Home Battery Backup in Philadelphia, PA

On PECO's time-of-use option, a weekday 2–6 p.m. kWh costs about five times a midnight-to-6 a.m. kWh. And on July 11, 2026, four microbursts knocked out power to tens of thousands of customers across the region.

What a home battery runs during a Worcester winter outageThe grid is down and snow covers the array, so the grid-tied solar system produces nothing. The battery feeds a critical load panel, keeping the refrigerator, heating controls, well pump and networking running, while air conditioning, the electric range and the dryer stay off. A reserve floor is held back for outages.GRID DOWNSOLAR 0 kWFRIDGEHEATPUMPWIFIA/CRANGEDRYEROFFBATTERYreserve floor heldback for outages

PECO TOU (Jun–Nov 2026): 32.404¢ peak · 9.336¢ off-peak · 6.741¢ super off-peak · July 11, 2026: 46,000+ regional customers out at peak.

The short answer

Philadelphia homes are served by PECO. Its optional Time-of-Use Pricing for June 1 to November 30, 2026 is 32.404¢ per kWh at the weekday 2–6 p.m. peak and 6.741¢ super off-peak (midnight to 6 a.m.), against an 11.759¢ standard Price to Compare.

On July 11, 2026, at least four microbursts with 60–70 mph winds tore through West and South Philadelphia. More than 46,000 utility customers in the region lost power at the peak. A battery covers both cases: shifting the peak window and holding chosen circuits through an outage.

PECO rates and outages in Philadelphia

From PECO's published Price to Compare and TOU table and contemporaneous reporting on the July 11, 2026 storms.

PECO TOU: peak is about 5× super off-peak

For June 1 through November 30, 2026, PECO's Time-of-Use Pricing Option for residential supply is 32.404¢ per kWh at peak, 9.336¢ off-peak and 6.741¢ super off-peak. The standard fixed Price to Compare for the same period is 11.759¢. Peak is weekdays 2–6 p.m.; super off-peak is midnight to 6 a.m. every day.

Winter TOU spread was similar

For December 1, 2025 through May 31, 2026, the TOU option was 32.747¢ peak, 8.382¢ off-peak and 6.061¢ super off-peak, against an 11.024¢ Price to Compare. PECO notes these generation prices exclude distribution charges, surcharges and taxes.

July 11, 2026: four microbursts in 30 minutes

The National Weather Service identified at least four microbursts between about 2:44 and 3:15 p.m., with 60–70 mph winds through Lower Merion, West and South Philadelphia. The Northeast Times, citing NBC10, reported more than 46,000 utility customers without power across the region at the peak. A little more than 3,000 PECO customers were still out Sunday evening.

Where a battery fits in Philadelphia

The bill case depends on TOU enrollment; the backup case depends on which circuits you need.

Shift the 2–6 p.m. window

A battery charged overnight at the super off-peak rate and discharged during the weekday peak is the bill case on PECO's TOU option. Whether it pays depends on how much of your load lands in those four hours — we look at your interval data before saying it does.

TOU is a supply choice, not a default

PECO's TOU pricing applies to customers who buy supply from PECO, have a smart meter and enroll. Customers on a competitive supplier, or on the standard fixed Price to Compare, do not see these peak and off-peak prices.

Solar owners: check how TOU affects net metering

PECO's own Q&A on TOU and interconnection says TOU may suit net-metered solar customers and EV owners, and that TOU changes how exported energy is valued. Read that document, or ask us to walk through your bill, before switching.

Backup for the summer storm pattern

The July 2026 event was a short, violent afternoon storm. Most customers were restored within a day or two, but a few thousand waited longer. Circuits for refrigeration, medical equipment, a sump pump and some cooling are the usual backup list.

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.

Peak is weekdays 2 p.m. to 6 p.m. Off-peak is weekdays 6 a.m. to 2 p.m. and 6 p.m. to midnight, plus 6 a.m. to midnight on weekends and holidays. Super off-peak is midnight to 6 a.m. every day.

What does PECO charge on TOU versus the standard rate?+

For June 1 to November 30, 2026, the TOU generation-plus-transmission prices are 32.404¢ peak, 9.336¢ off-peak and 6.741¢ super off-peak per kWh, against an 11.759¢ standard Price to Compare. These exclude distribution charges and taxes, and the next period's prices start December 1.

How bad was the July 2026 storm?+

At least four microbursts hit on July 11, 2026. More than 46,000 utility customers in the region lost power at the peak, according to NBC10 as reported by the Northeast Times. By Monday morning, CBS Philadelphia reported fewer than 800 PECO customers in Philadelphia still out.

Do solar panels keep my power on in an outage?+

Not on their own. Grid-tied inverters shut down when the grid is down. A battery and an isolating transfer device are what let solar keep chosen circuits running.

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. Coverage is confirmed per service area rather than promised as blanket availability.
