New power plants in the U.S. wait in line to connect to the grid
LOADSTAR reads the queue files of the seven U.S. ISOs and RTOs every day and publishes one number: how much of the capacity in line shows an executed interconnection agreement in the operator’s file.
Why it matters. New electricity demand, AI data centers included, needs new supply. This is the generation and storage capacity waiting to connect, as requested, not what will be built.
