Constellation Units to Pay $42,500 Under Texas Settlements

Two Exelon companies would collectively pay $42,500 under separate settlements with Staff of the Public Utility Commission of Texas relating to performance under the Emergency Interruptible Load Service (EILS) program.

Specifically, Constellation Alliance II, LP and Exelon Generation Company, LLC (on behalf of Constellation Energy Commodities Group, Inc.) have entered separate settlements with Staff to resolve investigations into alleged violation of Section 39.151(d) and (j) of the Public Utility Regulatory Act, P.U.C. SUBST. R. 25.503(f)(2), related to market participants compliance with ERCOT Protocols, and ERCOT Protocol § 8.1.3.1(6)(a), relating to Performance Criteria for Emergency Interruptible Load Service (EILS) Qualified Scheduling Entities (QSEs) obligations, on February 2-3, 2011.

Constellation Alliance II would pay $25,000 under its settlement, and Exelon Generation Company would pay $17,500 under its settlement.

The settlements state that on February 2, 2011, both Constellation Alliance and Constellation Energy Commodities Group failed, within 10 minutes of receiving ERCOT's Verbal Dispatch Instruction (VDI), to reduce operating at a load level higher than its declared maximum base load.

Constellation Alliance did not reduce its load level to no higher than its declared maximum base load until the interval ending at 09:15 AM, which was not within 10 minutes of the VDI. For the initial time interval when the Constellation Alliance EILS loads were expected to deploy, Constellation Alliance had curtailed approximately 10% of its contracted capacity.

Constellation Energy Commodities Group (CECG) did not meet its load reduction obligation until the interval ending at 06:30 AM, which was not within 10 minutes of the VDI. For the initial time interval when the CECG EILS loads were expected to deploy, CECG had curtailed approximately 79% of its contracted capacity.
