The state framework sets the default. Where KU (Kentucky Utilities) pays something different, the utility tariff governs and is what the card above reports.
| Compensation mechanism | Utility-specific net metering with dollar-denominated bill credits for exported generation under KRS 278.465-.468; the PSC sets the compensation rate in a utility-initiated ratemaking proceeding. |
|---|---|
| Export rate | There is no single statewide export rate. Current published utility examples are LG&E $0.07089/kWh residential, KU $0.07534/kWh residential, Duke Energy Kentucky $0.065427/kWh for both residential and non-residential customers, and Kentucky Power $0.09746/kWh residential and $0.09657/kWh commercial under NMS II. |
| Rate effective | Rates are utility- and tariff-specific. LG&E/KU's 2023-00404 NMS-2 rates were ordered August 30, 2024; Duke Energy Kentucky's current single ACEGC rate was ordered June 1, 2026; Kentucky Power's NMS II rates were set in the May 14, 2021 order. |
| Credit rollover | Yes. Excess dollar-denominated bill credits carry forward to the customer's next bill, subject to the utility tariff; they are not transferable between customers or premises. |
| Credit expiration | There is no annual statewide expiration date stated. If the customer closes the account, accumulated credits end with the account and no cash refund is paid; utility tariffs also state credits are not transferable between customers or locations. |
| Annual true-up | No annual true-up date is prescribed in the statewide statute; compensation and netting occur each billing period, with unused credits carried to the next bill. |
| Aggregate program cap | 1% of each retail electric supplier's single-hour peak load during a calendar year; once reached, the supplier has no further obligation to offer net metering to new customer-generators, subject to the statute and PSC-approved tariff implementation. |
| Program status | Utility-specific and threshold-based, not a single statewide closed program. The current LG&E/KU tariff states the companies cease offering NMS-2 to new customer-generators after the combined NMS-1/NMS-2 capacity reaches 1% of single-hour peak load and PSC approval is received; Duke's tariff framework uses the same 1% supplier threshold. |
| Grandfathering | Yes. For an eligible facility in service before the effective date of the initial PSC net-metering order, the tariff provisions in place when service began, including the one-to-one kWh credit, remain at the premises for 25 years, subject to the statutory conditions and the utility tariff. |
| Regulator | Kentucky Public Service Commission (PSC), which has jurisdiction over the retail suppliers' net-metering tariffs and sets utility-specific compensation through ratemaking proceedings. |
| Governing rule | KRS 278.465 through KRS 278.468, as amended effective January 1, 2020, plus each utility's PSC-approved net-metering and interconnection tariff. |
| Pending change | Yes. KU and LG&E filed a joint petition for reconsideration of the February 16, 2026 rate-case orders in Cases 2025-00113 and 2025-00114; the filing seeks changes to several issues while identifying the NMS-2 rates as retained at their current levels in the final orders. |
