Data Center Interconnection Queue: PJM, ERCOT, and NYISO

This is the large load interconnection queue: 1,100+ data center, fab, and industrial requests totaling 260+ GW across PJM, ERCOT, and NYISO. Each row carries an energization probability so headline queue megawatts are not treated as certain load.

Frequently asked questions

What is a large load interconnection request?

A request by a large electricity customer, such as a data center, semiconductor fab or hydrogen plant, to connect new demand to the transmission grid, usually 20 MW or more.

Which grids does the Large Load Monitor cover?

PJM, ERCOT and NYISO today, covering 1,100+ requests and 260+ GW, with MISO, ISO-NE, CAISO and SPP planned.

How is energization probability estimated?

An interpretable model scores each request on study stage, substation headroom, site control and regulatory signals, then weights MW by probability and expected timing.
