Each Maryland utility has different net metering rules, rebate programs, and pitch angles. Selecting here loads the right calculator math and proposal template.
BGE
Baltimore Gas & Electric (Exelon subsidiary) · ~1.3M electric customers · Baltimore City + Baltimore/Anne Arundel/Howard/Carroll/Harford counties + parts of PG/Montgomery/Calvert · PJM BGE Zone · regulated IOU under Maryland Public Service Commission (PSC)
Full retail 1:1 net metering TODAY (energy credited at retail; indefinite credit-rollover election survives — 2023 law, that's crediting, not the term). The 2026 Utility RELIEF Act (Ch. 353 / HB 1532) made the grandfather TERM Commission-determined and undetermined; new solar after July 1, 2027 gets no NEM.

BGE VPP pilot (Case 9761, DRIVE Act) PENDING — positioning only, never income. Every battery add follows the MD two-track configuration rule. 2012 derecho ~430K peak / 762K+ customer-outages over ~9 days.
Lead with: 2026 law made your NEM term finite (PSC-set, undetermined) + approved MYP climb + RCES $5K reserve-first + 2012-derecho resilience — battery structured to the MD two-track rule
Pepco
Pepco (Potomac Electric Power Company, Exelon subsidiary) · ~582K Maryland customers (the ~894K figure is MD+DC combined — MD-only is ~582K) · Montgomery + Prince George's counties · PJM PEPCO Zone · regulated IOU under Maryland Public Service Commission (PSC). Maryland-only — D.C. rates and rulings do not apply.
Full retail 1:1 net metering TODAY (indefinite credit-rollover election survives — 2023 law, that's crediting, not the term).

Every battery add follows the MD two-track configuration rule. 2012 derecho ~483K out across MD+D.C.
Lead with: 2026 law made your NEM term finite (PSC-set, undetermined) + recurring Pepco rate asks + RCES $5K reserve-first + DC-metro resilience — battery structured to the MD two-track rule
Delmarva Power
Delmarva Power (Exelon subsidiary) · ~205K Maryland electric customers · Eastern Shore MD (Salisbury/Ocean City/Somerset/Dorchester/lower shore) · PJM DPL Zone · regulated IOU under Maryland Public Service Commission (PSC). Maryland-only — Delaware rates and filings do not apply.
Full retail 1:1 net metering TODAY (indefinite credit-rollover election survives — 2023 law, that's crediting, not the term). The 2026 Utility RELIEF Act (Ch. 353 / HB 1532) made the grandfather TERM Commission-determined and undetermined; new solar after July 1, 2027 gets no NEM. All-in ~22.5¢/kWh — the HIGHEST of the 4 MD IOUs (heaviest distribution ~7.15¢); customer charge $9.43. MYP ~$28.9M (2023-25) extended to 6/30/2026 — a successor filing is likely. NO VPP pilot (the pending MD pilots are BGE's and Pepco's). Every battery add follows the MD two-track configuration rule. Eastern Shore storm isolation (Isaias 2020 + Feb 2026 blizzard).
Lead with: 2026 law made your NEM term finite (PSC-set, undetermined) + the highest MD rates + RCES $5K reserve-first + Eastern-Shore resilience — battery structured to the MD two-track rule
Potomac Edison (MD)
Potomac Edison (FirstEnergy subsidiary) · ~285K Maryland customers · western Maryland (Frederick, Washington, Allegany, Garrett, plus edges of Carroll/Howard/Montgomery) · PJM APS Zone · regulated IOU under Maryland Public Service Commission (PSC).

All-in ~13.2¢/kWh — the LOWEST of the 4 MD IOUs (customer charge $6.00), so the today-rate-hedge is smaller — but the sharpest documented FORWARD pressure: MD OPC found the western-MD APS zone faces the largest MD bill impact (~24%) from the 2025/26 PJM capacity results, via competitively-bid SOS. NO VPP pilot (FirstEnergy has no MD battery program). Every battery add follows the MD two-track configuration rule. Western-MD winter (Feb 2014 ice / mountain wind).
