ERCOT counts on an adequate supply of electric generation to meet demand and maintain capacity reserves to help support grid reliability if shortfalls occur.
This section includes access to ERCOT market studies and analysis materials related to resource adequacy as well as ERCOT short- and long-term forecast reports on generation supply and demand.
Reports produced prior to 2012 are located in the yearly archive section of Reports and Presentations

ERCOT developed a drought risk monitoring tool to screen for potential drought-related impacts to generation resources. The tool predicts whether water supplies used by generation resources in the ERCOT region are at risk of reaching levels requiring closer monitoring over the next 6 to 18 months, based on the most recent reservoir and lake levels from the Texas Water Development Board (TWDB) and historical trends in water usage. The documents available in this section include summaries of the results of this analysis, documentation of the tool methodology, and other related reports.

Resource Adequacy Assessments
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.
Capacity, Demand and Reserves Report
This biannual report contains a 10-year forecast of electric use and expected generation resources.
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.
