Pepco VPP pilot filed (up to 185 MW flexible-load resources); same PSC docket cycle as BGE — pending approval, not yet enrolling. PJM PEPCO Zone capacity-cost pressure flowing through riders.
Lead with: 1:1 NM preserved + Pepco VPP pilot pending + RCES $5K grant + DC-metro resilience
Delmarva Power
Delmarva Power (Exelon subsidiary) · Eastern Shore MD + portions of Delaware · MD-only customer count not cleanly broken out · PJM DPL Zone · regulated IOU under Maryland Public Service Commission (PSC)
Full retail 1:1 net metering for residential systems ≤ 100 kW, indefinite credit rollover (MD statutory). PTC 12.09¢/kWh (Mar-May 2026). Customer charge $8-$12/mo (Phase A research could not directly verify the exact figure — refine via tariff PDF re-fetch). NO VPP pilot filed (Exelon focus is BGE/Pepco). PJM DPL Zone capacity-cost pressure flowing through riders.
Lead with: 1:1 NM preserved + RCES $5K grant + Eastern Shore coastal resilience + system takeover
Potomac Edison (MD)
Potomac Edison (FirstEnergy subsidiary) · ~285K customers · 7 western Maryland counties (Frederick, Washington, Allegany, Garrett, Carroll, Howard, Montgomery — western edges) · PJM APS Zone · regulated IOU under Maryland Public Service Commission (PSC)
Full retail 1:1 net metering for residential systems ≤ 100 kW, indefinite credit rollover (MD statutory). PTC 11.19¢/kWh (Mar-May 2026) — LOWEST of the 4 MD IOUs. Customer charge $8-$12/mo (Phase A research could not directly verify exact figure — refine via tariff PDF re-fetch). NO VPP pilot filed (FirstEnergy posture in MD is different from Exelon). PJM APS Zone — same zone as APCo VA; capacity-cost pressure flowing through riders. FirstEnergy's OH territory saw 27-28% supply hikes — different state, different regulator, but the parent-company capital-recovery posture is the same.
Lead with: 1:1 NM preserved + RCES $5K grant + western MD mountain resilience + system takeover
