Brattle has filed with the Texas PUC a presentation concerning the impact of proposed ORDC changes
The presentation assesses several candidate wider curves, selected from stakeholders and ERCOT proposals, to show a range of possibilities.
The presentation shows
• Each curve's parameters and shape
• Whether each curve reaches HCAP before PRC < 3000
• Impacts on prices and CC revenues assuming dynamic self-commitment but static investment
• Impacts on reserve margins and reliability assuming dynamic self-commitment and investment (such that prices equilibrate to long-run marginal cost) and no additional measures to support resource adequacy
The analysis does not account for extreme supply shortages as observed in February 2021, "and thus overstates reliability absent other measures to prevent such shortages; modest changes to the ORDC cannot be viewed as a solution to such risks," Brattle's presentation states
