Texas QSE To Pay $240,000 Under Settlement With PUC Staff
The following story is brought free of charge to readers by VertexOne, the exclusive EDI provider of EnergyChoiceMatters.com
Enerwise Global Technologies LLC would pay $240,000 under a settlement with Staff of the Public Utility Commission of Texas to resolve alleged violations of applicable rules and protocols relating to responsive reserve service (RRS) and emergency response service (ERS) obligations
The settlement states, "Between September 17, 2021 and December 30, 2022, Enerwise repeatedly failed to provide sufficient RRS or provide ERCOT appropriate justification and a plan to correct the shortfall within ten minutes of notification from ERCOT".
The settlement states that such failures occurred on 13 dates for a total of 435 SCED intervals, including 104 five-minute SCED intervals on July 13, 2022 and 158 five-minute SCED intervals on December 29, 2022
Regarding ERS, the settlement states, "Between June 22, 2021 and September 6, 2023, ERCOT performed unannounced tests of Enerwise’s ERS resources."
The settlement states, "On each of the test days, one of more of Enerwise’s resources failed to achieve both a test performance factor of 0.95 or greater and an EIPF [ERS Interval Performance Factor] for the full first interval of the test of 0.95 or greater."
The settlement states, "Despite multiple ERS resources failing three or more consecutive tests, Enerwise continued to offer those resources in the ERS program."
The settlement states that the ERS violations reflect, "one or more resources failing ERS deployment testing
over 19 non-consecutive days and continuing to bid resources despite repeated failures of deployment tests."
The settlement also lists three ERS performance violations in which Enerwise failed to provide the full ERS obligation during certain periods and failed to meet the 95 percent performance obligation
The settlement states:
"On July 13, 2022, at approximately 2:55 p.m., ERCOT issued instructions to Enerwise to deploy non-weather sensitive ERS-30 and, at approximately 4:03 p.m., issued another deployment of ERS-30 for the new time period.
"ERCOT’s post-event analysis showed that Enerwise failed, during both deployments, to provide the full ERS obligation during the first full interval for ERS-30 and had an overall EVENTPF [event performance factor] of 83.30 percent.
"On September 6, 2023, at approximately 7:44 p.m., ERCOT issued instructions to Enerwise to deploy ERS-30.
"ERCOT’s post-event analysis showed that Enerwise failed to provide the full ERS obligation during the first full interval for ERS-30 and had an overall EVENTPF of 90.02 percent."
The $240,000 penalty under the settlement would be payable in 12 monthly payments of $20,000.
The settlement describes mitigating and corrective actions by Enerwise as follows:
"Regarding the RRS violations, Enerwise noted additional Load Resources that it used to meet its obligations on most of the instances in question. Enerwise also has implemented revisions to its approach of moving the obligation of a Load Resource when its telemetry is affected and its ability to provide RRS may be compromised; has increased the automation of its load scheduler; and has implemented a proactive approach to contacting ERCOT when Enerwise observes that its portfolio is experiencing any issues providing RRS.
"Regarding ERS testing and deployment performance, Enerwise demonstrated that despite individual resource testing issues, the company’s Portfolio Availability has consistently been greater than 95% since the February-May 2020 contract period. Enerwise also has removed several resources from its portfolio, stopped offering a resource pending further testing to ensure appropriate performance, and retained customers that have shown consistent passing performance of 100% or greater since December 12, 2022. In addition, Enerwise has increased internal staffing and implemented internal process changes to improve customer communication, customer compliance, testing compliance, and bid development. Enerwise also has increased automation in its dispatch system."
More specifically, Enerwise has agreed to remove certain ERS Resources, identified confidentially, from the program and will not offer them as ERS Resources.
An additional ERS Resource is identified, on a confidential basis, which Enerwise will not offer again as an ERS Resource until the customer demonstrates that such Resource is able to meet its performance
obligations by performing an Enerwise orchestrated test demonstrating the customer’s ability to meet or exceed the MW value to be enrolled in ERS 30 for the intended enrollment period.
