Why has the name plate capacity changed from 25 megawatt (MW) for the discharge unit in O.Reg.227/00 to 73 MW in O.Reg.127/01?
The name plate capacity of 25 MW for the discharge unit under O.Reg.227/00 refers to the electricity output, whereas the 73 MW refers to the total energy input per discharge unit under O.Reg.127/01. This is required because O.Reg.227/00 has been extended to include other sectors which may not generate electricity but have significant energy inputs to their processes. The 73 MW energy input value is derived by dividing the 25 MW electrical output value by the efficiency of the generation unit.
