Key Electricity Cost Drivers in Maryland
Primary market structure, generation mix, and environmental factors shaping electricity costs across Maryland:
1. Standard Offer Service (SOS) Auctions
The Maryland PSC oversees semi-annual wholesale auctions that establish default supply rates for utility customers who do not choose a third-party supplier.
2. EmPOWER Maryland Energy Efficiency Act
State efficiency programs fund rebate initiatives and grid upgrades through small monthly customer utility statement surcharges.
3. PJM Grid & Regional Transmission Charges
Wholesale pricing reflects PJM capacity auction results, regional transmission congestion, and Mid-Atlantic clean energy procurement rules.
