Twin Eagle Resource Management, LLC would pay $7,500 under a settlement with Staff of the Public Utility Commission of Texas to resolve alleged violations of ERCOT Nodal Protocols §§ 6.4.6(1) and former 5.5.2.

The settlement states that Twin Eagle was a Qualified Scheduling Entity (QSE) for Generation Resource Panda Temple Combined Cycle 1.

Under ERCOT Nodal Protocols § 6.4.6(1), QSEs must provide ERCOT with accurate telemetry of the current capability of each Resource including the Resource Status.

The settlement states that, "On January 13, 2017, at approximately 21:30, Panda Temple Combined Cycle 1 received a RUC instruction for three hours starting on January 13, 2017, hour ending 23, through January 14, 2017, hour ending 1."

The settlement states opting out of a RUC instruction (Resource Status code ONOPTOUT) means that the QSE chooses to self-commit the Resource and will provide the required energy based on its offer curve. Accepting the RUC instruction (Resource Status code ONRUC) means that the Resource will participate in the RUC settlement process, which includes setting the energy offer curve at the $1500 offer floor and contributing to the calculation of the Real-Time On-Line Reliability Deployment Price Adder.

The settlement states, "Twin Eagle expressed their intent to self-commit in response to the RUC instruction during a call with an ERCOT operator approximately five minutes after the instruction. To forward this goal, Twin Eagle telemetered Resource Status code ONOPTOUT for the RUC hours."

The settlement states, that, in January 2017, ERCOT Nodal Protocols § 5.5.2 provided the ability to opt out of a RUC instruction by updating the Current Operating Plan (COP) and setting the Resource Status in the COP to ONOPTOUT before the end of the Adjustment Period (one hour before the beginning of the RUC hour). ERCOT Nodal Protocols § 5.5.2 did not provide the ability to opt out of a RUC instruction by telemetering ONOPTOUT during the Adjustment Period until June 2017, when Nodal Protocol Revision Request 744 was implemented.

The settlement states, "Twin Eagle received the RUC instruction 30 minutes before the beginning of the RUC hour. Twin Eagle could not effectually update its COP to ONOPTOUT because the Adjustment Period was closed. Therefore, Twin Eagle should have telemetered ONRUC instead of ONOPTOUT, acknowledging that opting out was not feasible and accepting the RUC instruction."

The settlement states, "Twin Eagle provided 100% of the energy required by the RUC instruction."

The settlement states, "This Agreement represents a compromise of claims and allegations, and the execution of this agreement does not admit the truth or accuracy of anything contained in this Agreement, the Proposed Order, or any such disputed claims."
