Large-load and data center interconnection
Large loads such as data centers enter the grid through load interconnection requests, and the public pages treat them unevenly. NYISO reports large-load requests in its Gold Book with summer and winter MW in separate columns. TNEI manages data-center requests from 10 MW to 500 MW and above, Nira models generation and load development, and GridCARE says it has qualified 5 GW across the US.

Where large-load requests show up
How rows are readPublished load readings
The queue tracker separates requested MW, conditional study classifications and signed contracts. Each reading names its population and date:
- ERCOT: Conditional base load, 66,400 MW (2026-09-03)
- ERCOT: Conditional studied load, 127,900 MW (2026-09-03)
- ERCOT: Conditional studied load (chart), 125,400 MW (2026-09-03)
- ERCOT: Excluded from Batch Zero, 302,200 MW (2026-09-03)
- ERCOT: Load requests (preliminary), 458,700 MW (2026-05-19)
- AEP Ohio: Load requests (prior interest), 30,000 MW (2026-02-12)
- AEP Ohio: Paid study requests, 13,022.7 MW (2026-02-12)
- AEP Ohio: New-tariff contracted load, 5,642 MW (2026-02-12)
- AEP Ohio: Pre-tariff contracted load, 12,219 MW (2026-02-12)
- AEP Ohio: Total contracted load, 17,861 MW (2026-02-12)
- Dominion Zone: Delivery-point requests, 70,000 MW (2026-02-02)
- Dominion Zone: Requests with assigned dates, 25,000 MW (2026-02-02)
- Salt River Project: Transition cluster requests, 7,200 MW (2025-10)
Operators
NYISO’s 2024 Gold Book lists queue position, owner or operator, project and zone for large loads; it is historical reporting, not a current wait estimate. IESO, AESO and BPA also list load connections beside generation; the other operator pages in this table describe generation and storage queues.
Software
PowerClerk handles large generators and large loads in one workflow. Smarter Grid Solutions connects distributed generation, storage and large loads within network limits.
Advisory and capacity discovery
Enerzinx covers renewables, data centers and utility-scale energy. ICF supports generation and load connections, and Pterra does load interconnection engineering. GridCARE Power Finder identifies latent grid capacity and its Energize product supports flexible loads.
