How much of the pipeline is real

An interconnection agreement and a construction start are the two strongest signals that a queue project will be built. A listed date that has already passed is the strongest sign it will not be built on time.

0% of Southern Company's planned MW in the seven ISO queues is past due, against 11% for all developers.
