ERCOT puts surveyed connection requests at 177 GW
ERCOT's preliminary large-load survey responses cover approximately 177 gigawatts of requested grid connections, the Texas grid operator said, with West Texas accounting for 73 GW, or 41% of capacity. The figures describe connection requests, not approved, built or contracted demand.
In a Nov. 4 filing prepared for the Public Utility Commission of Texas' Nov. 5 open meeting, ERCOT said 433 of 465 loads had responded to its State and Community Impact request for information. That is 93% of the loads surveyed, covering approximately 97% of requested interconnection capacity, according to ERCOT. The percentages measure different things: response count and requested capacity.
The results, filed in PUCT Project No. 59142, are preliminary as of Nov. 5 and subject to change. A separate utility survey has a response deadline of 5 p.m. CST on Nov. 6.
All 245 large loads, defined as requests of at least 75 megawatts, responded to the community-impact survey. ERCOT said 417 responses arrived on time and 16 arrived late; 32 medium-load responses remained outstanding.
The detailed capacity and location charts use a reviewed dataset of 429 loads, rather than the full 433 responses. The location chart assigns zones using facility coordinates. ERCOT cautioned that the zone assigned when a facility connects can differ. West Texas has the largest share of requested capacity in the preliminary count, not a majority.
The survey also leaves gaps in project information. ERCOT said respondents answered 83% of nearly 67,000 questions. Projects planning to connect in 2028 or later returned more answers marked not applicable or unable to answer, which ERCOT linked to their earlier stage of development.
Separately, ERCOT's Batch Zero eligibility review remains incomplete. Staff and outside counsel have reviewed first-round responses from 257 developers. Recurring problems include missing documentation of related companies, inability to demonstrate control of a site, uncertainty over equipment delivery before connection and difficulty confirming financial security amounts.
ERCOT said it was issuing second-round requests and expected to send them to 80% of developers. Those requests give developers five business days to explain deficiencies. The filing does not say that the full 80% had already received them.
The separate medium-load survey went to 132 utilities on Oct. 26, one request per utility. It covers connection requests for 10 MW to less than 75 MW received from July 1 through Oct. 31. The filing sets the Nov. 6 deadline but does not establish that utilities have submitted their answers. ERCOT plans to follow up with utilities that do not respond; the timing of a later round to update responses is not set.
