4 Years

Average Queue Time

When a project does clear its feasibility study, the real wait begins. The national median from interconnection request to energization is 4 years for utility-scale solar, 38 months for storage, 5 years for onshore wind, and 19 months for a substation upgrade[6].

A four-year queue means carrying deposits on land nobody is allowed to build on, month after month, for 48 straight billing cycles. It means re-bidding transformer contracts twice before a shovel moves. For developers holding a signed offtake agreement, every restudy is another renegotiation — and financing does not wait politely.

Gigawatts Waiting

Over 2,300 gigawatts of generation and storage sit in U.S. interconnection queues — close to double everything currently plugged in. For most of it the constraint isn't the resource. The power is there. The wires are not.[7]
