Texas QSE to Pay $50,000 Under Settlement

Exelon Generation Company, LLC would pay $50,000 under a settlement with Staff of the Public Utility Commission of Texas to resolve allegations that Constellation Energy Commodities Group violated Electric Reliability Council of Texas (ERCOT) Protocols §§ 8.1.3.1, relating to Performance Criteria for Emergency Interruptible Load Service (EILS), and 8.1.1.4.2, relating to Responsive Reserve Service Energy Deployment Criteria.

ERCOT Protocols § 8. 1.3.1(6)(t) requires an EILS load to achieve an EILS Event Performance Factor (EILSEPF) of at least 0.95.

On August 4, 2011, ERCOT deployed EILS at 15:54:31. The settlement states that CECG failed to curtail its EILS loads within ten minutes. The settlement states that CECG's EILSEPF, calculated by ERCOT in accordance with Protocols § 8.1.3.1(6), was 0.69.

ERCOT Protocols § 8.1.1.4.2(1)(b) requires a QSE providing Responsive Reserve Service (RRS) to have a Load Resource (LR) response that is not less than 95% or more than 150% of the requested MW deployment ten minutes after a VDI.

On August 24, 2011, ERCOT issued an instruction to all QSEs with LR providing RRS to deploy Group 1 of their LR assets. . The settlement states that 10 minutes after the dispatch instruction, CECG had deployed 46 percent of its Group 1 LR assets.
