Which utility serves this customer?
Each West Virginia utility has different net metering rules, rebate programs, and pitch angles. Selecting here loads the right calculator math and proposal template.
Appalachian Power WV
Appalachian Power (AEP subsidiary) WV · ~430-440K WV customers · southern WV service area (Charleston / Huntington / Beckley / Bluefield corridor) · regulated IOU under WV Public Service Commission oversight · PJM APS Zone
Post-sunset since March 1, 2026 (application cutoff) / September 1, 2026 (completion cutoff). New residential NM applicants credited at ~12.4¢/kWh export vs ~17.2¢/kWh retail — ~4.8¢/kWh spread on every self-consumed kWh the battery shifts. Post-sunset customers are metered on SEPARATE gross import/export registers (no netting), so that spread is real and battery-addressable (addressable slice = full retail − export credit). COHORT NOTE: customers grandfathered on pre-sunset 1:1 retail NM are on NETTED full-retail terms — for them the battery bill value is ~0 (same class as OH/MO); the tool screens cohort before quoting spread savings and pitches resilience-first to grandfathered customers. April 2026 +4% rate hike effective June 1, 2026 (~$4.84/mo on a 1,000 kWh bill). ~25% rate growth over the past 5 years per WV PSC filings. APCo also serves VA under a separate (1:1 NM preserved) regulatory regime — verify customer is in WV territory before quoting these dynamics.
Lead with: Post-sunset EDG spread + PJM APS Zone rate hedge + derecho/winter-storm resilience + system takeover
Mon Power
Mon Power (Monongahela Power Company, FirstEnergy subsidiary) · north-central WV including Morgantown + the I-79 corridor · ~390K WV customers (combined FE WV operations ~545K with Potomac Edison) · regulated IOU under WV Public Service Commission · PJM
Post-sunset since January 1, 2025. New residential customers credited at $0.0934/kWh export vs ~13-14¢/kWh retail — ~4-5¢/kWh spread on every self-consumed kWh. Post-sunset customers are metered on SEPARATE gross import/export registers (no netting), so that spread is real and battery-addressable (addressable slice = full retail − $0.0934 export credit). COHORT NOTE: customers grandfathered on pre-sunset 1:1 retail NM are on NETTED full-retail terms — for them the battery bill value is ~0 (same class as OH/MO); the tool screens cohort before quoting spread savings and pitches resilience-first to grandfathered customers. FirstEnergy supply rates rose 27-28% in 2025 (PJM capacity-cost pass-through; PJM capacity costs spiked 833% in a single 2024 auction). FirstEnergy proposed +3% Aug 1, 2026 + +2.9% June 1, 2027 distribution increases on top of the 2025 supply hike. Same parent as OH's Ohio Edison + CEI + Toledo Edison; same structural rate pressure pattern.
Lead with: Post-sunset EDG spread + FirstEnergy 27-28% supply-hike pattern + derecho/winter-storm resilience
Potomac Edison WV
Potomac Edison (FirstEnergy subsidiary) WV · WV Eastern Panhandle (Berkeley / Jefferson / Morgan / Hampshire / Mineral / Hardy / Grant / Pendleton counties) · ~155K WV customers · regulated IOU under WV Public Service Commission · PJM
Sister utility to Mon Power — same FirstEnergy parent, same January 1, 2025 NM sunset, same $0.0934/kWh post-sunset export credit, same retail rate range ~13-14¢/kWh. Post-sunset customers are metered on SEPARATE gross import/export registers (no netting), so the ~4-5¢/kWh spread is real and battery-addressable (addressable slice = full retail − $0.0934 export credit). COHORT NOTE: customers grandfathered on pre-sunset 1:1 retail NM are on NETTED full-retail terms — for them the battery bill value is ~0 (same class as OH/MO); the tool screens cohort before quoting spread savings and pitches resilience-first to grandfathered customers. Same FirstEnergy 27-28% 2025 supply-rate hike and same +3% Aug 1, 2026 + +2.9% June 1, 2027 proposed distribution increases. Potomac Edison serves the Eastern Panhandle (Berkeley + Jefferson counties are the highest-growth WV counties; commuter overlap with DC metro adds bill-sensitivity context).
Lead with: Post-sunset EDG spread + FirstEnergy 27-28% supply-hike pattern + Eastern Panhandle winter-storm resilience
