At a glance
SERC covers much of the Southeast, a region of vertically integrated utilities, aggressive economic-development incentives, and accelerating datacenter recruitment in Georgia, the Carolinas, and Tennessee.
How does SERC compare with other grid regions?
By site count SERC is the 4th-largest of 9 regions GridCensus tracks, with 21,546 candidate sites. Its average DC Readiness of 55.8 is the 2nd-highest of 9, above the 53.0 national average. The average interconnection-queue wait of 4.3 yrs is the 6th-shortest of 9. Sites here see an average queue depth of 50 projects at their nearest point of interconnection. Catalogued substation capacity near these sites sums to 1.3M MW, a theoretical aggregate rather than available headroom.
Which states and site types make up SERC?
Florida (4,343 sites, 20%), Alabama (3,107 sites, 14%) and North Carolina (2,641 sites, 12%) hold the largest shares of the region's candidate sites. By type, substation-adjacent sites make up 40% (8,574; 26% nationally), industrial sites make up 22% (4,767; 24% nationally) and former mine sites make up 16% (3,513; 18% nationally).
