LG&E's voluntary residential Time-of-Day Energy rate, called RTOD-Energy, is the main tool for EV owners who want to cut charging costs. It is an opt-in alternative to the standard residential Rate RS. On-peak hours change across five seasonal periods, not two: winter (January through the 2nd Saturday in March, and the 1st Sunday in November through December) runs weekdays 6 am to 10 am and 6 pm to 10 pm; the spring and fall DST-transition weeks (2nd Sunday in March through March 31, and November 1 through the 1st Saturday in November) shift to weekdays 7 am to 11 am and 7 pm to 11 pm; and summer proper (April through October) narrows to a single weekday window of 2 pm to 6 pm. All weekend hours are off-peak year-round. Charging an EV overnight, or midday during the summer season, lands in the off-peak window, which is the point of the rate. The rate is best suited to drivers who can shift most charging out of whichever peak window applies for the current season.

LG&E does not pay a rebate for purchasing or installing a home Level 2 charger. The EV-specific incentive is the Optimized EV Charging managed-charging program, which pays $25 at enrollment and $5 per month to residential customers who let the utility optimize charging through a qualifying Level 2 smart charger or compatible EV. The RTOD-Energy rate and the Optimized EV Charging program can be used independently. LG&E's commercial EV offering is a turnkey hosting arrangement where the business pays installation and monthly hosting fees, not a rebate.

LG&E 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. LG&E and its sibling utility KU share the lge-ku.com site and nearly identical program designs, but they file separately: LG&E's current rates come from PSC Case No. 2025-00114, where the Kentucky PSC approved a settlement with modifications on February 16, 2026. LG&E serves the Louisville metro and nearby counties, while KU serves other parts of Kentucky.
