Golden Spread Electric Cooperative, Inc. would pay $25,000 under a settlement with Staff of the Public Utility Commission of Texas to resolve alleged violations of 16 Texas Administrative Code (TAC) § 25.503(f)(2), concerning alleged failure to adhere to Electric Reliability Council of Texas (ERCOT) Nodal Operating Guides § 7.1.2(1)(j), relating to QSE and TSP responsibilities and ERCOT Nodal Protocols § 8.1.1.4.3(3), relating to Non-Spinning Reserve Service (NSRS) Energy Deployment Criteria.

That settlement states that, "On December 28, 2017, Golden Spread's XML communication facility experienced a power supply issue that caused it to go off-line. The facility remained off-line for a total of 27 days. During this period, ERCOT sent an NSRS deployment instruction to Golden Spread. Because of the off-line status, Golden Spread did not receive the instruction."

That settlement states that, "Golden Spread's ELK2 generation resource is qualified to provide NSRS. On January 23, 2018, ELK2 had an off-line NSRS responsibility of between 85 and 190 MW."

That settlement states that, "Within twenty minutes of receiving an NSRS deployment instruction from ERCOT, Golden Spread must update the telemetered Ancillary Service Schedule for the off-line generation resource to reflect the deployment amount, which indicates to Security- Constrained Economic Dispatch that the resource is available to be deployed."

That settlement states that, "Within twenty-five minutes of receiving an NSRS deployment instruction from ERCOT, Golden Spread must ensure that ELK2 is on-line with an energy offer curve, and the telemetered net generation for the resource must be greater than or equal to the resource's telemetered LSL in megawatts multiplied by P1, or 0.90. Once ELK2 has met that threshold, Golden Spread must telemeter the resource status code 'ON' to indicate that the resource is online."

That settlement states that, "On January 23, 2018 at 06:43 AM, Golden Spread received an NSRS deployment instruction from ERCOT for its ELK2 generation unit. Because the XML communication facility was down, Golden Spread did not receive the deployment instruction and failed to meet all three requirements for the ELK2 unit."

That settlement states that, "To mitigate the occurrence of similar violations in the future, Golden Spread has added various redundancy systems to lessen the likelihood of future communication failures and to better detect any failures if they do occur."
