Mississippi Power Company

Mississippi Power does not offer a separate time-of-use rate built around EV charging. The utility states that customers who drive plug-in vehicles take its standard residential rate, and it has signaled that EV-specific rates may come later. In practice this means there is no off-peak window that lowers the price of overnight charging below the standard residential energy charge. EV owners on Mississippi Power pay the same per-kWh price to charge at 2 a.m. as they would running any other appliance.

Where Mississippi Power does help is on upfront cost. Residential customers can claim a vehicle rebate, up to $1,250 for a new EV, $1,000 for a leased EV, $750 for a used EV (purchase price $10,000 or more) or new plug-in hybrid, and $500 for a leased or used plug-in hybrid, plus $250 toward a Level 2 home charger. The rebate forms say to apply within 120 days of the vehicle purchase or lease and to allow about 16 weeks for processing; Mississippi Power reserves the right to modify or cancel the rebates at any time. These rebates do not depend on any rate enrollment. Commercial customers follow a separate form, with $2,000 per Level 2 charger, also applied for within 120 days of purchase.

Mississippi Power is the Southern Company subsidiary covering the Gulf Coast and Pine Belt, and it is distinct from Entergy Mississippi, which serves other parts of the state. Confirm your service territory on a recent bill before applying, since the two utilities run separate programs.
