Kentucky Utilities Co

KU offers a voluntary residential Time-of-Day Energy rate (Rate RTOD-Energy) as an opt-in alternative to the standard residential rate. On-peak hours are weekdays from 6 am to 10 am and 6 pm to 10 pm Eastern Standard Time, shifting one hour later during Daylight Saving Time. All weekend hours are off-peak. The PSC approved a settlement effective January 2026; the current approved rates are in the KU tariff on file at psc.ky.gov/tariffs. The rate is limited to 500 participants, accepted first-come, first-served.

KU does not offer a separate rebate for purchasing or installing a Level 2 EVSE. The utility's EV financial program is the Optimized EV Charging demand response initiative: residential customers on the standard Rate RS who enroll a qualifying Wi-Fi-connected Level 2 smart charger or compatible EV receive a one-time $25 enrollment incentive and an ongoing $5 monthly participation incentive. Enrollment and account management occur through the ChargingRewards platform. The utility may invoke up to 10 demand response events per year during periods of extreme grid stress; participants who opt out of those events forfeit the monthly incentive and may be disenrolled. The RTOD-Energy rate and the Optimized EV Charging program can be used independently.

KU is an integrated investor-owned utility in a traditionally regulated state; the Kentucky PSC sets its rates through contested rate cases rather than through a competitive retail market. KU also serves a small slice of southwestern Virginia covering five counties and one independent city (Norton), where customers are served under KU's Kentucky franchise and Kentucky PSC-approved rates.
