Carve-out: 2% solar PV by 2020
Tracking system: PJM-Generation Attributes Tracking System (PJM-GATS)
Maryland has a renewable portfolio standard to reach 20% renewables by 2020, including 2% solar PV. Midmarket customers may be eligible for several incentives offered by the Maryland Energy Administration. The Maryland Public Service Commission (PSC) has approved its final regulations for establishing a three-year pilot community solar program.
- The PSC opened submission for community solar pilot subscribers in April 2017. Applications received after May 5, 2017 will be processed in order of receipt.
Net metering is available until the aggregate capacity of all net-metered systems reaches 1.5 GW. Net excess generation is carried over as a kilowatt-hour credit for 12 months and reconciled after the 12-month period at the commodity energy supply rate the commodity energy supply rate.
System size limit: 2 MW
Aggregate cap: 1,500 MW
Credit: Net excess generation is credited at the retail rate.
RECs: Customers retain ownership of renewable energy certificates (RECs).
Meter aggregation: Virtual net metering is allowed for agricultural customers, non-profits, and municipal governments.
The 2008 rules apply to interconnections of all types of distributed generation systems of less than 10 MW for all types of utilities. PJM Interconnections are exempt from this rule. Maryland interconnection rules cover four tiers, which are subject to specific technical screens and review procedures.
System size limit: 10 MW
Liability insurance: Not required for Level 1, required for Levels 2, 3 and 4 ($2 million per occurrence and $4 million in aggregate for systems larger than 1 MW).
External disconnect switch: Required ("lockable isolation device" or "draw-out type circuit breaker with a provision for padlocking at the draw-out position").
Third Party Ownership
Third party power purchase agreements are allowed in Maryland.
In 2015, the Maryland PSC began a three-year community solar pilot program. Pilot projects must be ≤2 MW and have at least two subscribers. Individual subscriptions are capped at 200 kW (or 60% of the project's total subscription). The Maryland PSC determines compensation rates. The PSC opened submission for community solar pilot subscribers in April 2017. Applications received after May 5, 2017 will be processed in order of receipt.
