What does your utility pay?

No single rate — formula based

Formula, not a single published dollar rate: monthly excess-kWh credits are valued at the participating account's volumetric supply-service plus distribution-service charges, excluding societal-benefits-program charges.

Delmarva Power & Light · Delaware

Effective January 1, 2024 for the monthly excess-kWh credit formula.

Delmarva's customer-facing interconnection checklist says customers generating renewable electricity can interconnect and receive bill credits for excess generation; the applicable credit depends on the account rate schedule under 26 DE Admin. Code 3012.

Delaware requires electric suppliers and electric distribution companies to offer net metering for eligible customer-generators. For commission-regulated utilities, including Delmarva Power, monthly excess-kWh credits are valued at the sum of the account's volumetric supply and distribution charges, excluding specified societal-benefits charges; this is a rate-schedule formula, not one statewide dollar-per-kWh rate. Credits offset later monthly usage, but as of May 31, 2023 unused credits at the end of the annualized billing period revert to the EDC without reimbursement. Systems generally may not exceed 25 kW per Delmarva residential meter, 2 MW per Delmarva nonresidential meter, or 150 kW per Delmarva farm meter, and production is generally limited to 110% of expected consumption. The PSC regulation also permits an 8.0% system-wide penetration stop and states a future carryover change due by December 1, 2026.

Program details

Compensation mechanismNet metering credits excess kWh against subsequent monthly consumption. Effective January 1, 2024 for residential and nonresidential commission-regulated customers, the monthly credit is valued at the sum of the account's volumetric supply-service and distribution-service charges, excluding societal-benefits-program charges.
Export rateThere is no single statewide dollar-per-kWh export rate: the monthly excess-kWh credit is the sum of the participating account's volumetric supply-service and distribution-service components, excluding societal-benefits-program charges, according to that account's rate schedule.
Rate effectiveThe rate formula is effective January 1, 2024.
Credit rolloverYes. Excess kWh credits are credited to subsequent billing periods to offset consumption until all credits are used, before the end of the annualized billing period.
Credit expirationAt the end of the annualized billing period, excess kWh credits revert to the electric distribution company; the utility shall not reimburse, credit, or otherwise remunerate the customer for them.
Annual true-upThe annualized billing period is 12 consecutive monthly billing periods; the first begins on the first day of the first full monthly billing period after interconnection and generation begin.
Residential system cap25 kW per Delmarva meter for residential customers.
Commercial system cap2 MW per Delmarva meter for nonresidential customers; 150 kW per Delmarva meter for farm customers, subject to the stated DNREC exception process.
Aggregate program capAn EDC may elect not to provide net metering to additional customers if total customer-generation using net metering exceeds 8.0% of the capacity necessary to meet the EDC's average Delaware transmission peak demand for the preceding 3 years.
Program statusThe 8.0% threshold is an elective stop: an EDC may elect not to provide net metering services to additional customers after the threshold is exceeded.
RegulatorDelaware Public Service Commission.
DocketPSC Regulation Docket No. 65; Order No. 10644 adopted the 2025 amendments to the net-metering rules.
Governing rule26 Del. Admin. Code 3012, Rules for Regulation of Net Metering, implementing 26 Del.C. § 1014.
GrandfatheringThe rule states that eligibility for net-energy-metering services is not limited by direct ownership, joint ownership, or third-party ownership or financing of the generating facility, where net metering would otherwise be available.
Interconnection applicationA customer-generator facility must satisfy 26 DE Admin. Code 3012, meet applicable NEC, IEEE, and UL safety and performance standards, and comply with the electric supplier's interconnection tariffs and operating guidelines; Delmarva's process uses a two-part interconnection application and agreement.
Interconnection timelineThe reviewed statewide rule does not specify a single completion deadline; it requires interconnection and operation in parallel with the EDC's transmission and distribution facilities and directs interconnection requirements to a standard tariff.
Pending changeThe Delaware Public Service Commission adopted amendments to 26 DE Admin. Code 3012 (Rules for Regulation of Net Metering) as final by Order No. 10908 dated December 17, 2025, published in the March 1, 2026 Delaware Register of Regulations; the order takes effect 10 days after final publication.

Rates by utility

State rules set the framework. Individual utilities often pay something different, and where they do the utility tariff governs.
