Kentucky's post-2020 net-metering framework uses utility-specific, dollar-denominated bill credits for exported electricity rather than a single statewide export rate. Eligible facilities are generally limited to 45 kW, credits carry forward by billing period but are not cash-refunded at account closure, and preexisting customers retain the applicable legacy one-to-one kWh credit for 25 years. The Kentucky Public Service Commission sets utility-specific rates through ratemaking proceedings; current published examples are LG&E $0.07089/kWh, KU $0.07534/kWh, Duke Energy Kentucky $0.065427/kWh, and Kentucky Power $0.09746/kWh residential.

Program details

Compensation mechanismUtility-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 rateThere 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 effectiveRates 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 rolloverYes. 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 expirationThere 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-upNo 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.
Residential system cap45 kW rated capacity for an eligible electric generating facility; the statute does not create a separate residential cap.
Commercial system cap45 kW rated capacity for an eligible electric generating facility; the statute does not create a separate commercial cap.
Aggregate program cap1% 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 statusUtility-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.
RegulatorKentucky Public Service Commission (PSC), which has jurisdiction over the retail suppliers' net-metering tariffs and sets utility-specific compensation through ratemaking proceedings.
DocketKey implementation and rate dockets read: 2019-00256 (implementation discussion), 2020-00174 (Kentucky Power), 2020-00349 and 2020-00350 (KU/LG&E), 2023-00404 (KU/LG&E rate update), 2023-00413 (Duke), and 2025-00258 (Duke rate update).
Governing ruleKRS 278.465 through KRS 278.468, as amended effective January 1, 2020, plus each utility's PSC-approved net-metering and interconnection tariff.
GrandfatheringYes. 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.
Interconnection applicationApplication is utility-specific. The KU/LG&E interconnection tariff requires a Level 1 or Level 2 Application for Interconnection and Net Metering; Level 1 is for qualifying certified inverter-based systems, while Level 2 applies when Level 1 conditions are not met and may require technical documentation and fees.
Interconnection timelineNo single statewide review timeline is stated. Under the KU/LG&E tariff, the company must notify a Level 1 applicant within 20 business days whether the request is approved or denied; time awaiting additional information is excluded.
Pending changeYes. 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.
