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.

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.

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).
