Project #40268

PUC Rulemaking to Amend PUC Subst. R. §25.505, Relating to Resource Adequacy in the Electric Reliability Council of Texas (ERCOT) Power Region

Summary

The proposed amendments will amend §25.505(g), relating to the scarcity pricing mechanism, by increasing the high and low system offer caps and the peaker net margin, and to remove outdated portions of the rule.

Although Texas currently has an adequate and reliable supply of electricity available to meet its projected demands, the Electric Reliability Council of Texas (ERCOT) has projected that capacity reserves will decrease over the next several years. The proposed amendments allow for a structured increase in bid caps applicable in the ERCOT market and other changes to the scarcity pricing mechanism, ensuring that the ERCOT market sends the appropriate price signals to encourage development of generation resources.
