Filing excerpt
With the implementation of real-time co-optimization in December 2025, the ORDC was replaced by individual ancillary service demand curves (ASDCs) that are designed to mimic the operation of the ORDC.
The replacement of the ORDC scarcity pricing mechanism with new Ancillary Service Demand Curves (ASDCs) requires Vistra to update its bidding strategies and optimization models for its Texas generation fleet. This change necessitates investment in software, analytics, and consulting to maintain competitiveness.
