PGRR145 / NPRR1325 · the batch study process
The Batch Zero clock.
On 2026-06-02 the ERCOT Board approved PGRR145/NPRR1325 — the revision package that ends the serial large-load study process and replaces it with batches.[1] Recommended effective 2026-07-11, pending PUCT, which takes the package up on 2026-07-09. Eight days after that PUCT meeting, the first hard deadline lands. Miss it and a project is excluded from Batch Zero.

Dates from the PGRR145 Board Report (2026-06-02), verified against the June 1–2, 2026 Board materials. “Pending PUCT” means the deadline sits inside the Board-approved package and takes effect subject to PUCT approval. Day counts are end-of-day Central time.
How the batch study works, in plain English
Until now, every large load (≥75 MW) was studied one at a time, in the order it showed up — a serial queue that produced the 410-GW pile-up. Batch Zero studies everyone who qualifies at once.[1]
Get in. By 2026-07-10, an interconnecting large-load entity must submit its study and dynamic-model data plus eligibility materials. That date is also the last day for legacy approvals under the serial process. By 2026-07-24, the transmission or distribution provider files the qualification package — attestations, disclosures, financial-security confirmations — and projects electing the PCLR pathway file Form W Part A (notarized and binding). ERCOT flags incomplete packages by 2026-08-07; the roster is fixed at the final inclusion cut, 2026-08-31.
Get studied. ERCOT studies the batch as a group and publishes the final report with MW allocations on 2027-04-09. Allocated MW is reserved against restudy; a commitment gate — signed interconnection agreement plus financial commitments — converts an allocation to firm, and non-committed projects are automatically removed. The minimum allocation threshold is roughly 100 MW (90% for requests of 100 MW or less).[1]
Or get curtailable power sooner. The PCLR election (Provisional Controllable Load Resource) trades firmness for speed: firm service up to a load-commitment limit, with consumption above it curtailable via SCED dispatch, ahead of transmission buildout. It is not an eligibility bypass, and the obligations run with the facility.[1]
Miss it, wait. Projects excluded from Batch Zero wait for Batch 1 — a potential case build in June 2027.[1]
The money attached to a request, as proposed under 16 TAC §25.194 (PUCT Project 58481). The docket shows no adoption order — these numbers bind nobody yet, and the docket is the place to watch.[2]
- $100k / $300k
- Study fee — $100,000 for 75–249 MW; $300,000 at 250 MW and above.
- $50k per MW
- Financial security, roughly 20% refundable on withdrawal.
- $50k per MW
- Non-refundable interconnection fee on contracted demand, with staged refunds over five years of operation.
A 300-MW data center under the proposal: $300k study fee + $15M security + $15M interconnection fee. Source: proposed rule text, docket 58481 (203 filings and counting; watch the docket for the order, not law-firm alerts for a date).
