West Penn Power & solar.

FirstEnergy's West Penn Power territory wraps around Pittsburgh to the south, east, and north. Lower rates than Duquesne mean slightly longer paybacks, but the net metering rules are the same statewide.

1:1

kWh for kWh

Each kWh you export offsets one kWh you import later, at the full retail rate, on the kWh-based parts of your bill.

↻

Monthly carryover

Extra kWh roll forward month to month, so summer surplus covers the dark winter months.

5/31

Annual true-up

Each May 31, West Penn Power pays out any leftover credit at the price to compare, which is less than retail. So don't oversize your system.
