  1. Monthly Regulation Deployment Analysis – August ‘12 September QMWG

  2. Assumptions • The analysis presented here was done using 5 minute average, maximum and minimum data • For these purposes, the term “regulation deployed” refers to the total amount of regulation that was requested by ERCOT from the various QSEs and does not necessarily imply that the energy was realized • Load and wind volatility for a given interval was calculated as the difference between the average value for that interval and the average value for the previous interval • It should be noted that in the context of this analysis, “deviation” does not necessarily indicate that a Market Participant is behaving incorrectly • A WGR may “deviate” from expected during periods in which the weather is changing rapidly • A thermal generator may “deviate” from expected when shutting down as a result of the non-optimal method in use during the analysis period
