Texas PUC Staff Outline Potential Next Steps On Review of Operating Reserves Demand Curve (ORDC)
April 08,2016
Staff of the Public Utility Commission of Texas have filed a memo outlining potential next steps in the Commission's review of the Operating Reserves Demand Curve (ORDC), for consideration by the Commission.
Possible next steps raised by Staff include:
1. Allow ERCOT to gather more data. Because the ORDC has been in production for less than two years, the Commission could defer action and allow ERCOT to gather additional relevant data regarding its performance and effectiveness over time.
2. Order ERCOT to Perform Additional Analysis. The Commission could request that ERCOT conduct additional analysis, such as quantifying the expected equilibrium reserve margin for each proposal, undertaking additional study to determine a more accurate VOLL, analyzing the inputs to the LOLP calculation, or running additional backcasts. Cost estimates for such analyses have not yet been studied.
3. Hold a workshop. The Commission could convene a workshop to review stakeholder positions or other related issues. Such a workshop could be presided over by the Commissioners or by Staff.
Staff's memo also reviews stakeholder comments and ERCOT backcast results, and offers a summary of salient concepts and objectives regarding possible ORDC modifications set forth by the commenting parties.
