ERCOT said in a notice of the disposition of an Alternative Dispute Resolution (ADR) proceeding with the Lower Colorado River Authority (LCRA) that, pursuant to ERCOT Protocol Section 20.10.1(1), with respect to Settlement Interval ending 17:00 on Operating Day August 15, 2019, ERCOT will make an adjustment required to resolve this ADR through the issuance of Resettlement Statements to impacted Market Participants.

ERCOT will issue a separate Market Notice upon issuance of those Resettlement Statements.

ERCOT said that it misapplied Protocol Section 6.6.5.1(1), Resource Base Point Deviation Charge, when it imposed Base Point Deviation Charges on LCRA for the 15-minute Settlement Interval ending 17:00 on Operating Day August 15, 2019

ERCOT said that, "Protocol Section 6.6.5.1(1) states that a Qualified Scheduling Entity (QSE) for a Generation Resource must pay a Base Point Deviation Charge if it “did not follow Dispatch Instructions and Ancillary Service deployments within defined tolerances.” For the 15-minute Settlement Interval ending 17:00 on August 15, 2019, however, LCRA was following a Dispatch Instruction—issued by ERCOT at 15:50—to stay On-Line and generating through Hour Ending 17:00. Nodal Operating Guide 2.3.1.2(5) provides that “ERCOT, at its sole discretion, may request that the hydro Generation Resource(s) remain On-Line and generating after an initial deployment [of RRS].” Despite the Dispatch Instruction issued at 15:50, ERCOT systems automatically calculated a Base Point Deviation Charge for LCRA for the Settlement Interval ending 17:00 for Operating Day August 15, 2019, because during that interval LCRA’s units were in ONRR status and there was no RRS deployment. In such a case, the units’ Base Points are automatically set to zero in ERCOT’s systems. Because ERCOT’s automated systems did not take into account ERCOT’s 15:50 Dispatch Instruction, LCRA incorrectly incurred a Base Point Deviation Charge. Given this, ERCOT is granting LCRA’s ADR request for reimbursement of the Base Point Deviation Charges incurred for the 15-minute Settlement Interval ending 17:00 on August 15, 2019."

"These charges total $53,407.23," ERCOT said

With respect to the other three Settlement Intervals for which LCRA incurred Base Point Deviation Charges for the Operating Days at issue, ERCOT has determined that there is no basis to grant LCRA’s request for reimbursement. Unlike the Settlement Interval ending 17:00 on August 15, 2019, ERCOT has determined that LCRA was under no Dispatch Instruction from ERCOT to continue generating during these three Settlement Intervals.

ERCOT also denied separate relief sought under ADR from DC Energy and Monterey TX LLC
