EFOR is an indicator of the time the unit was forced out due to unplanned problems or equipment repairs, but also considers those periods when the unit is in service, but cannot reach full capability due to unplanned component or equipment repairs. These full forced outages and the equivalent full outage hours of the forced deratings are summed and compared to the actual time the utility wanted the unit in service. The resulting statistic is the EFOR. 14 New Generation Under Construction . Gordon Evans Combustion Turbines - Two 74 MW Simple Cycle CT's -June 2000 - One 150 MW Simple Cycle CT -June 2001 .
