In Part 3 of our five-part series on siting and scaling community solar, we examine the shifting regulatory and operational landscape facing Maryland community solar developers and project owners. While the federal One Big Beautiful Bill Act (OBBBA) has compressed renewable energy tax horizons nationwide, highly specific state-level clean energy mandates and utility rules dictate day-to-day project execution and asset underwriting.

What began in 2017 as a limited, three-year pilot program quickly transformed into a cornerstone of Maryland’s renewable energy strategy. Over a seven-year trial run, the state's pilot successfully nurtured 139 projects representing over 200 MW of capacity. This momentum led to the passage of Maryland House Bill 908 (HB 908) in 2023, which codified the pilot into a permanent state fixture. 

When the Maryland Public Service Commission (PSC) finalized the permanent program's regulations in February 2025, it lifted previous program caps and expanded individual project limits from 2 MW to 5 MW, cementing community solar as a long-term economic driver for the state.

Maryland's regulatory shift from pilot project to permanent program suggests immediate opportunity on paper. In practice, capital providers and developers face a far more complex grid infrastructure. Securing land and a conditional interconnection position no longer guarantees commercial viability. 

To successfully de-risk these assets, market participants must navigate three interconnected structural hurdles: a rigid geographic subscriber wall, an impending net-metering revenue cliff and thin-market LMI compliance risks.

Geographically matching subscribers to a project’s specific utility territory may be the norm across the country, but in Maryland, this dynamic forces developers into a difficult trade-off: "Should I build where land is affordable but the market is thin, or pay a heavy premium to build where subscribers are plentiful?" This operational dilemma plays out directly across Maryland's major utility footprints, drawing a sharp line between rural supply and urban demand.

To bypass the geographic wall, developers should prioritize securing commercial and industrial (C&I) rooftop solar rights on manufacturing or logistics facilities directly within BGE and Pepco territories. This approach positions capacity where customer demand is concentrated, driving down customer acquisition costs and reducing long-term subscriber churn risk. 

Furthermore, Maryland explicitly favors preferred sites, such as rooftops, parking structures and brownfields and allows larger co-located systems on them. The trade-off is a higher cost-per-watt footprint and roof/site agreements that must last the life of the project.

Beyond geographic constraints, project value stacks face severe regulatory volatility. Under Maryland HB 1532, the state is moving away from full 1:1 retail-rate net energy metering (NEM 1.0) toward a reduced-compensation successor framework (NEM 2.0). While the PSC has until February 1, 2027, to finalize the exact NEM 2.0 rate structure, industry projections indicate that export credits will fall well below full retail parity. Consequently, securing grandfathered status is one of the most important factors in determining an asset's long-term bankability and solar project debt sizing.

To protect pipeline valuations, asset owners must aggressively direct capital toward projects positioned to meet the 50% interconnection deposit milestone before the July 1, 2027 deadline.

Solar financial modeling should adopt a dual-track approach: calculate baseline debt sizing and investor returns against conservative NEM 2.0 rate projections, treating 1:1 retail pricing strictly as financial upside until the deposit milestone is fully executed. Additionally, EPC construction milestones and liquidated damages should be tied directly to the July 1, 2030 COD cutoff to insulate project yields from contractor delays.

The third operational hurdle is Maryland’s aggressive 40% Low- and Moderate-Income (LMI) subscriber mandate. While the state's adoption of income self-attestation significantly reduces upfront customer acquisition costs (CAC), maintaining that 40% threshold continuously for 25 years requires flawless subscriber asset management.

This challenge is severely compounded by the state's geographic mismatch. Projects built on lower-cost land in DPL or PE territories are legally forced to source their 40% LMI allocation from a small, low-density rural customer base. In these thin markets, customer churn creates immediate systemic compliance risk. Because a handful of residential cancellations can easily push an asset below the mandatory 40% floor, a project that drops out of compliance faces temporary or permanent removal from the program, putting its entire revenue stream at risk.

Fortunately, unallocated revenue isn't immediately lost, but the recovery window is tight. Since 2025, Maryland allows projects to bank unsubscribed energy and retroactively allocate those credits to new subscribers within a strict 12-month rolling window. Credits left unallocated past the 365-day mark are permanently paid out at utility avoided-cost rates, which represent a mere fraction of full retail value. Because each utility banked credits differently, owners need to monitor balances and expiration dates closely. Fast backfilling of churned subscribers protects both LMI compliance and the value of every banked credit.

Additionally, view the LMI mandate as an opportunity to reduce default risk and backfill churned accounts by partnering with a subscriber platform that can execute utility sizing and allocation integrations, automate account validation and provide 60-day remittance forecasting for seamless net-crediting integration across BGE, Pepco, DPL and PE.

Maryland’s transition to a permanent community solar market offers long-term regulatory stability, but the era of simple project underwriting is officially over. Maximizing project yields in this mature landscape requires a highly coordinated, automated asset management strategy that simultaneously accounts for utility geographic constraints, rigid interconnection queue management, collapsing rate designs and continuous subscriber operations.

In Part 4: The New Jersey Squeeze, we examine another Mid-Atlantic market transition. We will analyze how fixed incentive structures, strict LMI requirements, mandatory subscriber discounts and severe siting constraints are squeezing project margins across New Jersey’s community solar landscape.

Navigating state equity mandates while protecting project margins requires a subscriber management partner that understands local regulatory mechanics.

Solar Simplified helps community solar asset owners automate LMI verification, integrate with Utility Consolidated Billing frameworks, manage subscriber churn and maintain compliance throughout the life of the asset.
