Large loads and data centers

Your interconnection path, milestone by milestone.

Register a data center or other large load and follow its path in any of the 7 US ISOs, from the first request to approval to energize. Rule changes that touch large loads are matched to your site.

What changes for you

The rules that change for large loads.

Large load rules are being written now, in the ISOs, at FERC and in the states. These are the ones that set your timeline.

01

ERCOT large load interconnection

Loads of 75 MW and up: the request to the transmission provider, the Large Load Interconnection Study, the interconnection agreement and financial security.

02

ERCOT Batch Zero

The batch study for loads of 75 MW and up under PGRR 145 and NPRR 1325: how a load is classified, the MW it is allocated, and when it moves to a later batch.

03

Co-location and controllable load

Pairing a load with on-site generation behind one point of interconnection as a Withdrawal-Limited Private Use Network, and registering as a Provisional Controllable Load Resource, under the Batch Zero rules.

04

Approval to energize

The Planning Guide prerequisites: telemetry, the stability assessment and a current Load Commissioning Plan.

05

SPP High Impact Large Load

SPP's 90-day HILL Delivery Point Study for loads of 10 MW and up at 69 kV or below, or 50 MW and up above 69 kV, and the 150-day generation assessment when you pair the load with generation.

06

FERC and state proceedings

FERC and state commission proceedings on large loads, including the PUCT review that Texas SB 6 requires before a new large load nets with an existing generator.

What you get

What PhronEdge gives large loads.

Watch it work

A large load registration plan

Register the site as a large load in any of the 7 US ISOs. PhronEdge lays out each step with its owner, its documents and a citation to the rule.

The right steps for your setup

Batch Zero class, co-located generation and controllable load each add or remove steps, so the plan fits your site.

Changes matched to your site

When a rule touching large loads changes, the Attention tab shows what it means for your site and the action-by date.

Deadlines on your calendar

Every milestone and filing date on the calendar, and in your own calendar app through the calendar feed.

Cited answers from Relay

Ask how a protocol revision or a commission rule affects your load and get an answer cited to the source.

Live grid conditions

Load against peak, prices and the generation mix in your ISO in the Market tab.

In the product

A rule changes. You see what it means for your site.

PhronEdge maps the change to the asset it affects, explains what changed and why it matters, gives the act-by date and tells you what to do next.

How it works

How large loads use PhronEdge, in 3 steps.

1

Register the site

Choose the ISO, the load type and the expected peak demand in MW.

2

Get the path

Every step from the first request to approval to energize, with owners and documents.

3

Track the rule changes

New large load rules arrive matched to your site, with dates on your calendar.

Questions

What large loads ask us.

Something else on your mind? Book a call with us.

ERCOT's large load interconnection process applies to loads of 75 MW and up. PhronEdge flags a site below that threshold when you register it.

All 7. ERCOT, SPP and NYISO each run their own large load process. PJM, MISO, CAISO and ISO-NE have no load interconnection queue, so the plan follows the path through the Transmission Owner that serves the site. Each step carries its owner, its documents and a citation to the rule.

Data centers, crypto mining, hydrogen, industrial loads and others.

Yes. Link the site to a generation asset you have registered. In ERCOT that adds the co-location steps, and in SPP it adds the generation assessment.
