Texas QSE To Pay $50,000 Under Settlement With PUC Staff

CPS Energy would pay $50,000 under a settlement agreement with Staff of the Public Utility Commission of Texas to resolve alleged violations of, ERCOT Nodal Protocols § 8.1.1.4.2(1)(a), and ERCOT Operating Guide § 7.1.2(1)(j), "relating to CPS's alleged failure to respond to three Responsive Reserve Service (RRS) deployments due, in part, to issues associated with system upgrades, which impacted the inter-control communications protocol (ICCP) link."

The settlement states, "On April 30, 2019 at 21:37:20, ERCOT issued two RRS deployments: a 74.3 MW RRS deployment to QCPSE and a 36.6 MW RRS deployment to QCPSE2," both of which are CPS QSEs

The settlement states, "Neither QSE timely updated the RRS schedules for the units to which it had assigned the RRS obligations, preventing Security Constrained Economic Dispatch (SCED) from dispatching the required RRS MWs."

The settlement states, "On July 15, 2019 at 14:37:32, ERCOT issued a 39.1 MW RRS deployment to QCPSE2. The QSE did not timely update the RRS schedule for the unit to which it had assigned the RRS obligations, again preventing SCED from dispatching the required RRS MWs."

The settlement details various corrective actions undertaken by CPS, including training and system changes
