Are regional transmission organizations the future for renewables in the Southeast?

Renewable energy, particularly solar, is poised for significant growth in the southeastern United States. The Southeast has also mostly retained a vertically integrated utility model, and most utilities in the region have not joined a Regional Transmission Organization or Independent System Operator (collectively known as, RTO). Recent developments have led stakeholders and policymakers in the Southeast to rethink whether it is beneficial for some utilities to join RTOs – something that is generally seen as a positive development for renewable energy.
