Power pipeline — the interconnection queue
What's coming, not just what's built: generation and storage waiting to connect to the grid, by state — with the withdrawal reality applied.
Interconnection queues are the binding constraint on the AI buildout. Nationally, 1,745 GW of new generation and storage is waiting to connect — roughly 3× what’s operational today. But history is sobering: only 11% of requested capacity has historically reached operation, so the realistic near-term add is closer to 198 GW. Toggle the map between the raw queue and that withdrawal-adjusted view — the gap is the story.

What’s in the queue
by resource type| Resource | GW queued | Share |
|---|---|---|
| Solar+Battery | 404 | 23% |
| Solar | 397 | 23% |
| Battery | 385 | 22% |
| Gas | 240 | 14% |
| Wind | 178 | 10% |
| Other | 33 | 2% |
| Offshore Wind | 23 | 1% |
| Wind+Battery | 16 | 1% |
The grid’s near-term supply mix is overwhelmingly solar, storage and gas — what’s queued shapes what powers data centers next.
By grid region
ISO / RTOThe demand side — who’s waiting for power
The queue above is generation supply. The data-center demand queue (large loads waiting for power) is published unevenly by grid operators, so coverage is partial today — we show it where it exists and label the gaps honestly.

About the power pipeline
The U.S. interconnection queue holds roughly 1,745 GW of generation and storage seeking to connect to the grid — the forward-looking supply that will (or won’t) power the AI data-center buildout. Because only about 11% of requested capacity has historically reached operation, we show both the raw queue and a withdrawal-adjusted view. Data is from Lawrence Berkeley National Laboratory’s U.S. interconnection queue dataset (CC BY 4.0), as of 2026-06-18; see the methodology.
