Datacenter Sites by ISO / RTO Region

PJM coordinates the grid across 13 mid-Atlantic and Midwest states. It contains the world's densest datacenter cluster (Northern Virginia's 'Data Center Alley'), and its interconnection queue is the most closely watched speed-to-power constraint in the country.

WECC spans the entire western interconnection outside California's ISO, from the Rockies to the Pacific Northwest. Abundant hydro and renewables pair with rapidly growing load and long transmission distances.

MISO runs the grid across 15 central US states. Deep industrial land inventory and competitive power pricing make it an emerging datacenter frontier, though queue timelines have lengthened.

SPP coordinates the central plains. Among the windiest grids in North America, it offers some of the lowest energy prices and shortest queues — attractive for power-hungry, latency-tolerant workloads.

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.

ERCOT is the standalone Texas grid. Its connect-and-manage interconnection model offers the fastest path to energization in the country, fueling explosive datacenter and crypto load growth.

CAISO runs most of California's grid. Silicon Valley demand and aggressive clean-energy goals collide with high power prices and constrained transmission — a premium but challenging market.

ISO New England coordinates the six-state Northeast. Winter peaking, constrained gas supply, and limited land keep it a niche datacenter market, but proximity to Boston drives latency-sensitive demand.

NYISO operates the New York State grid. Upstate hydro and nuclear power pair with downstate latency demand, while transmission congestion between zones shapes where new load can connect.
