PROJECT OVERVIEW Mississippi Power and Origis Energy, along with officials from the Area Development Partnership and Lamar County, are working together on the Sumrall I Solar Project, the state’s largest solar facility.

When operational, the $100-million facility will have a capacity of 52 megawatts (MW) and will generate enough electricity to power approximately 8,000 homes.

Origis Energy, a global solar company powering the solar revolutionSM with utility scale, commercial and public sector solar energy systems worldwide, will build, own, and operate the solar project. Mississippi Power will receive all the energy and associated renewable energy credits produced by the facility, which it may use to

serve customers with solar energy or sell to third parties for the benefit of customers.

Origis Energy will construct the solar facility on 590 acres in Sumrall. The project will create up to 100 jobs during construction. It is scheduled to be completed by the first quarter of 2017 and will have a 25-year power purchase agreement with Mississippi Power.

Above is a photograph showing the type of ground-mounted installation Origis Energy will be using the Sumrall I Solar Project. The facility will utilize 215,000 polycrystalline solar panels mounted on single-axis trackers. The site will be interconnected to the Mississippi Power transmission system.
