The units for EPT don't make sense. First, in the numerator, MW (megawatts) is a unit of power (energy per unit time), not energy. Second, in the denominator, the units are energy MWh (megawatt-hours). The overall unit is thus 1/h; it should be a unit of time, not reciprocal time (which could be a unit of frequency). Confusion of units is common in the press; I hope someone who knows an accepted or "received" definition of EPT will correct this.--Egnatoff 13:02, 16 October 2009 (UTC)
