BGE Net Metering + Maryland SREC Market + Baltimore City ≠ County AHJ
BGE Credits Solar Exports at Full Retail Rate. Maryland SRECs Earn Per MWh. Baltimore City and Baltimore County Are Completely Separate Jurisdictions — Confirm Before You Build.
BGE (Baltimore Gas and Electric, an Exelon subsidiary) serves the Baltimore metro with net metering at the full retail rate, as required by Maryland law. Maryland's Solar Renewable Energy Credit (SREC) program adds a second layer of financial benefit — solar owners earn one SREC per megawatt-hour of generation, sellable on the Maryland SREC market. Baltimore City and Baltimore County are completely separate governmental jurisdictions in Maryland: Baltimore City is an independent city not part of Baltimore County. The building departments are separate, the permit portals are separate, and routing to the wrong one results in immediate rejection. We confirm AHJ per address before building every Baltimore plan set.
BGE Net Metering · Full Retail Rate · Required by Maryland Law
✅BGE net metering: credits solar exports at full retail electricity rate
✅Maryland law requires BGE to offer net metering for residential solar
✅BGE interconnection application: submit simultaneously with building permit
⚠️Some outer BGE service territory may have different program terms — confirm per address
✅Maryland property tax exemption for solar energy systems — permanent
MD SRECs · Baltimore City ≠ Baltimore County · NEC 2020
✅Maryland SRECs: earn 1 credit per MWh of solar generation — sellable on the MD SREC market
✅SREC registration through PJM-GATS — ongoing annual income for the system lifetime
⚠️Baltimore City is an independent city NOT part of Baltimore County — separate AHJs
⚠️Baltimore City Dept of Housing ≠ Baltimore County Permits — routing wrong = rejection
✅NEC 2020 under Maryland state adoption — consistent across all BGE service territory
⚠️ Baltimore City and Baltimore County are completely separate jurisdictions with separate building departments. Baltimore City is an independent city in Maryland — it is not part of Baltimore County. A plan set addressed to Baltimore County for a Baltimore City address (or vice versa) is rejected immediately. We confirm the correct AHJ for every address before building.
Why Baltimore Installers Outsource
City vs County AHJ Confusion. MD SREC Registration Not Included. BGE Interconnection Not Formatted.
Routing Baltimore City Address to Baltimore County Permits — or Vice Versa
Baltimore City and Baltimore County are legally separate jurisdictions in Maryland. Baltimore City Department of Housing and Community Development handles city permits. Baltimore County Permits and Development Management handles county permits. These are different offices, different portals, different fees. Routing to the wrong jurisdiction results in immediate rejection — no overlap in authority.
Maryland SREC Registration Not Included in Project Package
Maryland SRECs require registration in PJM-GATS for the solar system to earn and trade credits. SRECs provide ongoing annual income for the system lifetime. Installers who don't walk Baltimore customers through SREC registration leave meaningful annual income on the table. We include MD SREC registration documentation guidance in every Baltimore plan set deliverable.
BGE Interconnection Format — Maryland-Specific Application Requirements
BGE's interconnection process for residential solar follows Maryland PSC regulations with specific documentation requirements. Generic interconnection packages not formatted for BGE's Maryland-specific forms may require revision requests that delay the interconnection approval timeline. We format every Baltimore plan set for BGE interconnection submission.

Four Things That Define Solar in Baltimore.
MD SRECs
Maryland Solar RECs — Earn One Per MWh · Sellable on the SREC Market
Maryland's SREC program lets solar owners earn one Solar Renewable Energy Credit for every megawatt-hour of solar generation. SRECs are registered in PJM-GATS and can be sold to utilities or on the open market. MD SREC prices fluctuate based on utility compliance demand under Maryland's Renewable Portfolio Standard. For Baltimore solar customers, MD SRECs are a meaningful second financial benefit layered on top of BGE net metering — ongoing annual income for the system lifetime.
City ≠ County
Baltimore City and Baltimore County Are Completely Separate Jurisdictions
Baltimore City is an independent city in Maryland that is not part of Baltimore County — a distinctive legal structure unlike most US metros. Each has its own building department, permit portal, fee schedule, and permit process. Baltimore City Department of Housing handles city permits. Baltimore County Permits and Development Management handles county permits. Howard County, Anne Arundel County, and Harford County each also maintain their own separate building departments.
BGE NEM
BGE Full Retail Net Metering — Required by Maryland Law
BGE (Baltimore Gas and Electric, an Exelon subsidiary) offers net metering at the full retail electricity rate as required by Maryland law. Monthly excess generation credits roll forward with annual true-up. BGE serves approximately 1.3 million electric customers in central Maryland. BGE's residential solar interconnection process under 10 kW is well-established.
Healthcare Market
Baltimore — Hopkins, UMMS, and the Mid-Atlantic Healthcare Corridor
Baltimore is home to Johns Hopkins Hospital, University of Maryland Medical System, MedStar Health, and dozens of affiliated research and clinical facilities. This healthcare concentration creates large commercial rooftop and carport solar demand. The Port of Baltimore logistics corridor and the growing biotech sector in the I-270 corridor also create commercial solar opportunities.
