Plain-English framing: ERCOT runs the Texas grid. The waitlist for new very-large electric loads (mostly data centers and crypto) is over 230 GW — more than the entire current ERCOT system peak. Batch Zero is a one-time amnesty-style process to clear that backlog under shared rules, instead of making every project wait years. The centerpiece — the Provisional Controllable Load Resource (PCLR) — lets a data center connect early in exchange for agreeing that ERCOT can curtail it in real time down to its 'minimum firm load' until the transmission upgrades that would let it run full-out are built. It is the load-side mirror of how curtailable generation already plugs in. The May 13 TAC meeting was the last serious chance for material amendments. The ERCOT comments filed May 11 — on MW allocation methodology and studied-load treatment — are the ones to read carefully because they determine how Batch Zero slots get rationed between projects if applications exceed available headroom. The June 1 Board vote is procedurally a rubber stamp; the rules are effectively final now. The operative date for developers is July 24 — the Declaration of Intent deadline. Miss it and the project drops to the ordinary queue.

Why it matters
Nine weeks remain until July 24. This is the only live deadline in U.S. data-center site readiness where the structured filing that developers must produce (Form W Part A + modeling data including the per-study-year minimum firm-load limit) is also exactly the dataset Cliff's approval-outcomes corpus needs to capture. Two product implications: (1) Before June 1, the public ERCOT docket should be re-scraped to confirm the May 13 TAC vote text and any last-second amendments to the MW allocation / studied-load treatment language. Even one tweak there changes how a developer should size and time their Declaration of Intent. (2) The July 24 cutover is the natural cutoff for a 'Batch Zero filing assistant' surface: ingest a developer's project spec (location, peak MW, ramp curve, expected minimum firm load), produce a draft Form W Part A and modeling-data package, flag missing inputs. The same surface re-positions cleanly as the PCLR contract-negotiation aid post-July-24 for projects that won a slot. Pair with the PUCT financial-security rule (16 TAC §25.194, $50k/MW non-refundable) so the developer sees the ERCOT timing gate AND the PUCT cost gate in one underwriting view.
