Connecting to the Grid

Once you have determined that you are Ready for Solar, you may begin the process of connecting your solar system to Mississippi Power’s grid.

Below are the steps needed to connect your system to the grid:

Step 1 — Utility Application and Agreements

For systems 20kW and less

Apply to interconnect your system with our Mississippi Power electric grid using the application provided below for renewable systems producing up to 20kW of power. The application includes an interconnection agreement establishing your responsibility for the safe and lawful operation of the solar system.

We advise you to:

  1. Complete the application with your solar installer.
  2. Return the completed application and agreement to the email or postal address listed on the application.

For systems over 20kW

If your project is over 20kW, other policies apply. Please contact one of our energy experts for more information at 1-855-693-8326.

Step 2 — Installation and Operation

When you are finished with Step 1 and have a conditionally approved application, your installation may begin. Follow the steps below to begin your installation.

  • You or your installer should contact:
    • Local building and electrical code offices to see if permits are required
    • Homeowner associations, if applicable, to determine any community restrictions
  • Your system will need to be installed to the latest version of the National Electric Code (NEC) and other applicable codes. A certificate of completion is required from code officials before testing or long-term operation begins.
  • Mississippi Power may need to replace the electric meter at your home. This will require a brief service interruption.
  • Your qualified installer should perform tests to determine if the system is operating correctly according to the Mississippi Public Service Commission's interconnection rules. Have your installer notify Mississippi Power 48 hours before the day of this testing, as the company is required to observe these tests before authorizing long term operation. During these tests, Mississippi Power will also verify that the installed equipment conforms to the submitted application.
  • Upon satisfactory completion of the above tests and a receipt of the required certificate of completion, Mississippi Power will authorize your PV system to be placed in operation.
