The state framework sets the default. Where Delmarva Power (MD) pays something different, the utility tariff governs and is what the card above reports.
| Compensation mechanism | Net energy metering: generation and consumption are netted over the billing period; net excess generation is credited and paid under the statutory accrual choice. |
|---|---|
| Export rate | No single statewide export price: for the annual-accrual option, net excess generation is valued at the electric company's generation or commodity portion of the customer's applicable rate, averaged over the prior 12 months; indefinite-accrual value is set by a PSC method. |
| Rate effective | Current statutory framework: 3,000 MW cap effective October 1, 2021; indefinite net-excess-generation accrual option enacted effective October 1, 2023. |
| Credit rollover | Customer may accrue net excess generation for up to 12 months ending with the billing cycle immediately before the end of April, or (for eligible customers other than the stated municipal/cooperative exceptions) elect indefinite accrual; the utility carries credits forward until offset, the accrual period expires, or the account closes. |
| Credit expiration | Annual-accrual credits settle at the end of the 12-month period ending with the billing cycle immediately before the end of April; indefinite-accrual credits remain until offset or account closure, with payment at closure under the statute. |
| Annual true-up | Billing cycle complete immediately before the end of April; annual-accrual payment is due on or before 30 days after that cycle. |
| Aggregate program cap | 3,000 MW statewide rated generating capacity for eligible customer-generators. |
| Program status | Open on installed-capacity data: 1,537 MW, or 51.23% of the 3,000 MW cap, was installed as of June 30, 2025. The PSC reports approximately 2,911 MW of pending community-solar projects, so the pipeline nearly exceeds the cap before existing capacity is included. |
| Grandfathering | No separate statewide grandfathering provision was verified in the current sources reviewed; the 2023 change is described as an election to accrue indefinitely, and the statute preserves customer-generator ownership of renewable attributes/RECs. |
| Regulator | Maryland Public Service Commission. |
| Governing rule | Md. Code, Public Utilities Article §7-306; interconnection standards are COMAR 20.50.09, with net-metering/aggregation provisions also in COMAR 20.50.10. |
