Market Design Analysis

The Public Utility Commission of Texas (PUC) and ERCOT Board have been evaluating possible approaches to encourage new generation development within the ERCOT region to maintain adequate capacity reserves. This section includes reports and presentations associated with this investigative effort.

Planning Reserve Margin Analysis

The ERCOT Board of Directors has established a minimum target reserve margin equal to 13.75 percent of peak electricity demand to serve electric needs in the case of very high demand or unexpectedly high levels of generation plant outages. This section consists of reports that describe the methodology and results of studies that help the ERCOT Board determine the appropriate target reserve margin.

Resource Adequacy Assessments

Capacity, Demand and Reserves Report

This biannual report contains a 10-year forecast of electric use and expected generation resources.

Seasonal Assessment of Resource Adequacy

The SARA is based on criteria similar to CDR, however the seasonal outlook reflects near-term weather forecasts, generator outage trends, and updates to the generation fleet. 

Wind and Solar

Wind and solar profiles for use in ERCOT planning studies, as well as files showing the derivation of wind and solar peak capacity percentages using approved CDR methodologies.
