Interconnection Queue
The backlog of energy projects (solar, wind, battery) waiting for utility approval to connect to the grid. As of 2024, over 2,000 GW of generation is waiting in U.S. queues.
Why It Matters
Residential solar interconnection is typically faster than utility-scale, but queue backlogs can still cause delays. In some utility territories, PTO wait times have increased significantly.
