Which utility serves this customer?
Each Pennsylvania utility has different net metering rules, rebate programs, and pitch angles. Selecting here loads the right calculator math and proposal template.
PECO
PECO Energy · Philadelphia metro + Bucks/Chester/Delaware/Montgomery/York county portions · ~1.6M customers · Exelon subsidiary
1:1 retail rate net metering at ~$0.21/kWh; monthly excess carries forward at retail, annual true-up May 31 settled at Price-to-Compare (~$0.11/kWh in 2026), not full retail. Residential cap 50 kW. No proposed changes to net metering policy as of Q2 2026. The most stable solar-economics market in PA.
Lead with: Stable 1:1 retail NEM + winter resilience + system rescue
PPL Electric
PPL Electric Utilities · central & eastern PA · Lehigh Valley (Allentown, Bethlehem, Easton), Wilkes-Barre/Scranton, Harrisburg metro, Williamsport, Pottsville · ~1.5M customers across 29 counties · PPL Corporation subsidiary
Currently 1:1 retail-rate NEM (~$0.21/kWh). PPL filed rate case R-2025-3057164 to move customer-generators from GSC-1 (fixed-price) to GSC-2 (hourly LMP-based credits) — estimated 70-80% reduction in NEM value. Settlement March 13, 2026. Grandfathered customers stay on GSC-1 for 10 years IF they (a) submitted interconnection app on/before Sept 30, 2025 AND (b) achieve PTO or Certificate of Completion on/before Dec 31, 2026. 10-year grandfathering protection is capped at 140 MW aggregate — oversubscription possible.
Lead with: URGENCY — 10-year grandfather closes Dec 31, 2026 (140 MW cap)
Duquesne Light
Duquesne Light Company · Pittsburgh + most of Allegheny County + parts of Beaver County · ~600K customers · independent (not FirstEnergy/PPL)
1:1 retail rate net metering at ~$0.18-0.20/kWh; monthly excess carries forward, annual true-up in June settled at Price-to-Compare (~$0.08-0.10/kWh), same convention as PECO and the rest of PA. Residential cap 50 kW. No proposed changes to net metering policy as of Q2 2026. Western PA solar production runs ~16% below eastern PA (~1,050 kWh/kW/yr vs ~1,250 in PECO/eastern PPL territory).
Lead with: Stable 1:1 retail NEM + winter resilience + western-PA reality
Met-Ed
Metropolitan Edison (FirstEnergy PA) · south-central PA · Reading, York fringe, Harrisburg metro fringe (areas not served by PPL) · ~565K customers
Currently 1:1 retail-rate NEM. FirstEnergy filed DSP-VII Feb 4, 2026 for 2027-2031 service period, moving customer-generators to Hourly Pricing Default Service Rider (MRPL-based) — structurally similar to PPL's GSC-2 change. Only 3 years of grandfathering proposed; intervenors arguing for 10. Implementation Jun 1, 2027. Met-Ed/PENELEC/West Penn/Penn Power legally consolidated into FirstEnergy Pennsylvania Electric Company (FE PA) on Jan 1, 2024 but operating brands retained.
Lead with: URGENCY — DSP-VII Jun 1, 2027 + 3-yr grandfather proposed (10-yr in play)
