PurposePurpose

(ERCOT)(ERCOT)Modifies Section 6.8.2.2 to explicitly state the Modifies Section 6.8.2.2 to explicitly state the criteria currently used to determine eligibility for criteria currently used to determine eligibility for Out of Merit Capacity (OOMC) startup costs, as Out of Merit Capacity (OOMC) startup costs, as well as clawback of startup costs and also well as clawback of startup costs and also incorporates ‘max zero’ logic into the settlement incorporates ‘max zero’ logic into the settlement formula that calculates the price for the startup formula that calculates the price for the startup costscosts

BenefitBenefit Provides clarity of the settlement rules, and a Provides clarity of the settlement rules, and a reduction of settlement and billing disputes.reduction of settlement and billing disputes.







ERCOT often receives settlement and billing ERCOT often receives settlement and billing disputes regarding eligibility for OOMC startup disputes regarding eligibility for OOMC startup costs and the associated clawback. These costs and the associated clawback. These settlement and billing disputes are mainly a settlement and billing disputes are mainly a result of a lack of understanding of the criteria result of a lack of understanding of the criteria used to determine startup and clawback used to determine startup and clawback eligibility. The criteria are currently reflected in eligibility. The criteria are currently reflected in the Charge Matrix posted on ERCOT’s website, the Charge Matrix posted on ERCOT’s website, but not in the ERCOT Protocols. Updating the but not in the ERCOT Protocols. Updating the Protocols to reflect the criteria documented in Protocols to reflect the criteria documented in the Charge Matrix as well as the settlement the Charge Matrix as well as the settlement practice for the clawback will provide the clarity practice for the clawback will provide the clarity needed to avoid such future settlement and needed to avoid such future settlement and billing disputes.billing disputes.


ERCOT also receives settlement and billing ERCOT also receives settlement and billing disputes and questions pertaining to the disputes and questions pertaining to the implementation of the “max zero” logic on the implementation of the “max zero” logic on the OOMC startup cost formula (PSOOMC startup cost formula (PSuiui).

PRR 676 (RPRS Solution with Nodal RUC-Type (RPRS Solution with Nodal RUC-Type Procurement and Cost Allocation), which was Procurement and Cost Allocation), which was approved by the ERCOT Board on 09/19/06, approved by the ERCOT Board on 09/19/06, included this logic. However, Replacement included this logic. However, Replacement Reserve Service (RPRS) settlement was the main Reserve Service (RPRS) settlement was the main focus of PRR 676 and following a market focus of PRR 676 and following a market participant appeal the PUCT ruled the PRR participant appeal the PUCT ruled the PRR should not be implemented. ERCOT reintroduced should not be implemented. ERCOT reintroduced the “max zero” logic in PRR 809 since it was the “max zero” logic in PRR 809 since it was collateral damage in the PRR 676 decision and collateral damage in the PRR 676 decision and the market had previously reached agreement the market had previously reached agreement that Generation Resources should not be charged that Generation Resources should not be charged for providing OOMC Service.for providing OOMC Service.
