Solar power in Mississippi

Mississippi has substantial potential for solar power, though it remains an underutilized generation method. The rate of installations has increased in recent years, reaching 438 MW of installed capacity in early 2023, ranking 36th among the states. Rooftop photovoltaics could provide 31.2% of all electricity used in Mississippi from 11,700 MW if solar panels were installed on every available roof.

In 2011, the Sierra Club sued the United States Department of Energy which was providing investment in a coal gasification plant being built by Mississippi Power. In 2012 Mississippi Power had only 0.05% renewables in its power mix. In a settlement in 2014, Mississippi Power agreed to allow net metering, and to offer 100 MW of wind or solar power purchase agreements. Mississippi is one of only two states, along with Florida, to have no potential for standard commercial wind power, having no locations that would provide at least 30% capacity factor, although 30,000 MW of 100 meter high turbines would operate at 25% capacity factor.

Mississippi Power which provides energy in southeast Mississippi has started a program to contract for 210 MW of solar power in 2014, possibly increasing to 525 MW. 100 MW would be from small scale distributed installations.

Offering net metering is required by federal law, but Mississippi is one of only four states to not have adopted a statewide policy on net metering, which means it needs to be negotiated with the utility.
