Texas PUC Issues Questions For Stakeholder Comment On Real-Time Co-optimization, Marginal Losses; Ask About Impact On Retail Market, Cost Recovery Mechanism

After finalizing the questions at yesterday's open meeting, the Texas PUC issued questions for stakeholder comment in Project No. 48540, Review of Real-Time Co-optimization (RTC) in the ERCOT Market, and Project No. 48539, Review of the Inclusion of Marginal Losses in Security-Constrained Economic Dispatch

Both sets of questions include questions about the impact on the retail market and retail customers from each proposed policy. Additionally, the questions ask for comment about costs incurred by market participants for implementation, and impacts on market participant systems and operations

For RTC, a question asks: What is the appropriate funding mechanism for the ERCOT implementation costs associated with RTC? How should these costs be recovered?

For marginal losses, a question asks: Assuming the Commission decided to go forward with implementation of marginal transmission losses, what are the key issues related to determining the appropriate treatment and allocation of the marginal transmission loss surplus revenues?

For RTC, a question added from the open meeting discussion is: What effects, if any, would the implementation of RTC have on existing administrative scarcity pricing mechanisms, such as the Operating Reserves Demand Curve and the Reliability Deployment Price Adder?
