In these comments filed with the Texas Public Utility Commission, RAP responds to recommendations made by other organizations in the PUC’s Project 40000, Proceeding to Ensure Resource Adequacy in Texas. In markets with a significant share of variable resources, such as exists in Texas, RAP recommends designing markets to properly value investment in the operational flexibility needed to ensure reliability. RAP suggests that an enhanced forward services market approach is consistent with existing market mechanisms and the PUC’s goals.
