EDF Energy Services, LLC (EDF) would pay $475,000 under a settlement with Staff of the Public Utility Commission of Texas to resolve alleged violations of ERCOT Nodal Protocols §§ 22.214.171.124, relating to
operational data requirements and, 126.96.36.199, relating to ancillary services capacity monitor.
A statement from EDF Energy Services is below
The settlement states that EDF is the Qualified Scheduling Entity (QSE) for CVC_CC1.
The settlement states that under ERCOT Nodal Protocols § 188.8.131.52, EDF is required to provide real-time telemetry
data to ERCOT, including Non-Frequency Responsive Capacity (NFRC).
The settlement states that under ERCOT Nodal Protocols § 184.108.40.206(2), each QSE is required to operate resources
providing ancillary service capacity to meet its obligations.
The settlement states that, "EDF is regularly awarded RRS [Responsive Reserve] ancillary service obligations for CVC_CC1. Commission Staff asserts
that between the dates of March 27, 2016 and December 28, 2017, there were 113 operating hours
for which EDF failed to reserve sufficient capacity to meet its RRS obligations. EDF asserts that a
calculation error resulted in inaccurately telemetered Non-Frequency Responsive Capacity
(NFRC) values leading to the appearance of a lack of headroom. EDF further asserts that
CVC_CC1 had enough physical headroom to provide the required RRS capacity and there
was no reliability risk to the bulk electric system."
The settlement states that, "Commission Staff asserts that NFRC miscalculations do not fully account for EDF's capacity
shortfall. Commission Staff further asserts that EDF had an obligation to telemeter accurate
NFRC values. Finally, Commission Staff asserts that failing to reserve sufficient capacity to
meet an RRS obligation and failing to telemeter accurate data can each pose a reliability risk
to the bulk electric system."
The settlement states that, "To prevent future violations, EDF has created an alarm to alert real-time operators of any
capacity shortfalls. EDF has self-mitigated the amount of RRS sold into the day-ahead
market and hired third party contractors to update the logic in the distributed control system
to accurately reflect the NFRC value."
EDF Energy Services provided the following statement concerning the matter: "EDF Energy Services, LLC was assessed an administrative penalty by the Texas PUC for failure to reserve adequate capacity for its Response Reserve (RRS) obligation as the QSE for a third-party power generation facility in 2017. The root cause for the capacity shortfall was identified to be the third party generation facility sending an incorrect Non-frequency Responsive Capacity (NFRC) calculation to EDF. EDF has implemented detective controls to help third-party generation facilities identify and mitigate the duration of any such issues in the future. Additionally, EDF has worked with generator owners to assist in the proper implementation of NFRC calculations at their respective facilities."
