The southeastern region of the United States has been slow to move away from fossil fuels (coal, oil and natural gas) because of the cost of renewable energy.
Numerous nuclear power plants were built in the region in the 1960s and 1970s. The capital cost to build and maintain the nuclear power plants to US Nuclear Regulatory Commission has proven significantly greater than forecast. Several nuclear power plants have been closed in the region over the previous decade.
The southeastern region of the US has significant solar potential. State regulators have resisted developing solar energy, because of the cost of the solar systems. However, the cost of solar systems has dropped significantly over the last few years. Utilities in the region are now beginning to integrate solar energy into the power grid.
Virginia is the latest southeastern state planning to develop renewable energy to replace fossil fueled power plants. Florida recently replaced an expensive coal fueled power plant with an inexpensive solar park. South Carolina is pursuing different solar projects to replace the power from a nuclear power plant that was closed in 2017. It cost $20 billion to close the nuclear power plant. Georgia is currently building the largest solar park in the southeast region of the United States.
