UFE Analysis Reports

Unaccounted-For-Energy (UFE) is calculated for each settlement interval as the difference between the total generation supplied to the ERCOT system and the total system load plus losses. UFE for each settlement interval is then allocated to the loads.

The annual UFE analysis report contains both ERCOT-wide and UFE allocation category quantities as follows:

  1. Total UFE MWhs;
  2. Total UFE cost;
  3. Percent of total UFE to ERCOT Load;
  4. Percent of total UFE cost; and
  5. Notice of any factors that may be contributing to UFE.

UFE analysis reports are prepared annually and posted by April 30 each year. In this section, you will find the UFE analysis reports beginning with 2002.
