ERCOT Resource Adequacy

Resource Adequacy at ERCOT

Any opinions voiced in the articles linked below are those of the article authors only, and not necessarily endorsed by Competitive Assets

The latest round of efforts to address generation concerns in ERCOT dates back to 2010, when the PUCT opened Project No. 37897, related to resource adequacy and shortage pricing (1/19/10).  Since then, the Commission has held a number of workshops, opened additional projects, reviewed consultant studies and stakeholder comments, and revised rules and ERCOT practices – all in an attempt to increase the planning reserve margin and/or forestall potential power shortages.  At the same time, ERCOT has been hard at work, developing new programs to increase load participation in the market, commissioning various studies, and working with stakeholders on relevant issues (e.g., to revise inputs into the Capacity, Demand, and Reserves (CDR) reports).  On August 29, 2013, the PUCT decided to move forward in addressing resource adequacy at ERCOT, including steps to implement the Operating Reserve Demand Curve (ORDC).  On this page, we will track the latest news about this work, including latest studies and decisions, and highlight pertinent reports.
