Texas Resource Entity To Pay $40,000 Under Settlement With PUC Staff
The following story is brought free of charge to readers by VertexOne, the exclusive EDI provider of EnergyChoiceMatters.com
El Campo Wind LLC would pay $40,000 under a settlement with Texas PUC Staff to resolve alleged violations of 16 Texas
Administrative Code (TAC) § 25.503(f)(10) related to compliance with Electric Reliability
Council of Texas (ERCOT) requests for information.
ERCOT uses the Power System Simulator for Engineering (PSS/E) modeling software tool
for transmission planning, simulation, and analysis. Pursuant to Planning Guide Revision
Request (PGRR) 085, ERCOT began transitioning its electric grid model from PSS/E v33
to PSS/E v35 modeling software for improved accuracy and to ensure greater reliability. The
transition required all Resource Entities with user defined dynamic models (DMs) to
upload updated DMs compatible with the new software and accompanying information
such as model quality tests (DM package). The deadline for Resource Entities to upload
their updated DM package to ERCOT was July 1, 2022.
According to a proposed order included with the settlement, El Campo is a Resource Entity that used user defined DMs. ERCOT required El Campo
to provide updated dynamic models, and associated information such as model quality
tests, compatible with ERCOT’s upgraded modeling software.
According to the settlement, El Campo submitted four DM packages to ERCOT before the July 1, 2022 deadline, but ERCOT
rejected each submission for failure to satisfy all requirements. The settlement states that El Campo therefore did not timely
submit all requested data by the deadline.
According to the settlement, El Campo in response to various requests from ERCOT provided multiple additional DM packages, but these subsequent submissions were also rejected as not acceptable
According to a proposed order included with the settlement, El Campo provided an updated DM package as required under PGRR 085 to ERCOT on
August 7, 2025. ERCOT accepted this model submission on May 5, 2026.
The August 7, 2025 date is 966 days after an extended compliance deadline of December 16, 2022, and 1,134 days after the
initial deadline established in Market Notice W-B031521-01.
The settlement states, "El Campo attempted in good faith to meet every DM modeling deadline established by
ERCOT; however, El Campo has been constrained from compliance with such deadlines
by the need to obtain information from the Original Equipment Manufacturer ('OEM') for
its wind turbines and the production of the requisite models and Model Quality Tests
('MQTs') by its engineering consultants. El Campo has no control over its OEM's or
consultants' response rate or workflow and is not able to produce the DM modeling
packages that ERCOT requires without reliance on these third parties".
Per a proposed order, El Campo indicated that corrective actions have been taken to timely provide necessary
data to ERCOT and to prevent further violations of Commission rules, including hiring additional regulatory staff and engineering consultants
The settlement states, "El Campo incurred significant out-of-pocket costs in retaining and hiring new engineering
consultants to engage with its OEM to provide several iterations of updated dynamic
models[.]"
