Summary

Mississippi's Renewable Energy Net Metering Rule requires Entergy Mississippi and Mississippi Power to offer net metering to any customer self-generating with renewables. Residential solar is capped at 20 kW nameplate DC, non-residential at 2 MW, all enforced by the Public Service Commission.

101 All EUs shall offer Net Metering to any customer that seeks to generate electricity on the customer's side of the EU's meter using Renewable Energy sources, provided: 1. For residential customers, Net Metering nameplate direct current capacity of the aggregated DGFs at the customer's premises shall be limited to 20 kW... 2. For non-residential customers... shall be limited to 2 MW... 102 EUs may refuse additional net metering requests if the total Net Metering direct current capacity... exceeds at any time 3 percent of the EU's total system peak demand...

Full Breakdown

There is no statewide solar-installation permit in Mississippi; roof systems clear local building and electrical permits. The statewide layer is the Public Service Commission's Renewable Energy Net Metering Rule (MRENMR) and companion interconnection rule (MDGIR). Under MRENMR 101, regulated utilities must offer net metering to renewable self-generators, with residential nameplate capacity limited to 20 kW DC and non-residential to 2 MW. To connect, a customer files a Standard Application and meets IEEE 1547 interconnection standards. Self-consumed energy offsets at full retail; exported excess earns the Total Benefits of Distributed Generation rate. Utilities may refuse requests once installed capacity reaches 3% of their prior-year system peak.

Violations & Penalties

A distributed generation facility that fails the MDGIR interconnection standards or IEEE 1547 testing is denied grid connection. A regulated utility that refuses an eligible net-metering request below the 3% cap answers to the Public Service Commission by complaint.

Frequently Asked Questions

Do I need a statewide permit to install solar in Mississippi?

No. There is no state solar-installation permit. Local building and electrical permits apply, and to net meter you file a Standard Application with your utility and meet the MDGIR interconnection standards.

Which utilities must offer net metering?

The rule binds regulated electric utilities, Entergy Mississippi and Mississippi Power. Electric cooperatives and municipal systems fall largely outside the Commission's net-metering mandate.

How is exported solar credited?

Energy you self-consume offsets at the full retail rate. Excess exported to the grid earns the Total Benefits of Distributed Generation rate: avoided cost of wholesale power plus 2.5 cents per kWh.
