Mississippi's Rule Right Now
Hooking up: residential systems of 20 kW or less at Entergy Mississippi use its Level 1 Interconnection Application and Agreement. Approval of the application and documents puts you in the Solar Net Metering Program. Your bill then shows a fee of $95 to $135 that is one-time and non-refundable. Only approved systems receive a connection from Mississippi Power as well.
Net metering: only Entergy Mississippi and Mississippi Power customers fall under the PSC's Renewable Energy Net Metering Rule; co-op members go by their co-op's rules. In practice, this is net billing: the utility buys exported power at avoided cost, then adds a 2.5 cents/kWh adder, and settles monthly. For residential systems, the cap is the smaller of 20 kW and 110% of annual peak demand.

Key Information for Mississippi
- Exported power earns little: in 2026, Entergy Mississippi's credit for power you send to the grid pays 6.1 cents/kWh, while customers with low and moderate income receive 8.1 cents/kWh. A plug-in kit earns its keep by covering what your home uses.
- Power is fairly cheap here: in 2024, homes paid an average of 13.39 cents/kWh, and across every customer group the state's average price ranked 33rd, so what you save on each kWh is modest.
- At Entergy Mississippi and Mississippi Power, the first 1,000 solar customers who qualify for low-income status get an additional 2 cents/kWh credit that lasts 15 years.
