Southwestern Electric Power Company (SWEPCO)

SWEPCO offers an optional residential time-of-use rate in Arkansas known as Rate Schedule 8. The on-peak window runs from 1:01 p.m. through 7:00 p.m. on weekdays, excluding national holidays, during July, August, and September only. Outside those hours, and during all other months, customers pay the lower off-peak rate. Enrollment requires an Advanced Metering Infrastructure (AMI) meter, and SWEPCO reserves the right to limit participation based on AMI availability. The specific peak and off-peak energy rates in cents per kWh were not publicly accessible during research and are flagged for re-verification. In Louisiana and Texas, no residential EV-specific TOU rate has been confirmed; customers in those states pay the standard residential rate.

A $250 rebate is available to SWEPCO residential customers who own or rent a single-family home and install an ENERGY STAR-certified Level 2 EV charging station. The rebate is funded on a first-come, first-served basis while funding lasts, and has been confirmed available in Arkansas, Louisiana, and Texas. A separate $250 rebate applies to multifamily Level 2 EV charging projects in Louisiana and Texas. These rebates do not require enrollment in any particular rate plan, so they can be combined with the optional TOU rate in Arkansas.

SWEPCO is a vertically integrated investor-owned utility regulated by three separate state commissions: the Arkansas Public Service Commission, the Louisiana Public Service Commission, and the Public Utility Commission of Texas. Its Texas service territory sits outside the ERCOT grid and operates under SPP (Southwest Power Pool), which means Texas customers deal directly with SWEPCO for rates rather than choosing a competitive retail provider. The Louisiana tariff includes Schedule 73, a pilot rate effective August 30, 2025, for commercial operators of public EV charging facilities; this is the utility's primary commercial EV infrastructure offering.
