Resource Adequacy 2016

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.

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, as well as materials with the PUC's review of the reliability standard for the ERCOT region.

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.
