Load factors to end June 2014

摘要

Data was available for 399 out of 428 operating nuclear power plants greater than 150 MWe in capacity, at the end of June 2014. The average load factor for this 371.9 GW fleet for the 12 months to June 2014 was 71.2 compared to an overall lifetime load factor average of 72.9%. The average load factor for the first six months of 2014 was 71.4%. That last figure seems to denote a recurrent trend in this report; there are a lot of instances of small improvements. Three of the four main reactor types show improvement in annual average load factor for three quarters in a row (not PHWRs). There are fewer lower-performing reactors (the group with load factors of less than 25% shrunk) while there were a greater number of better performers (the group with load factors from 85-89% load factor increased by 46 basis points from 12.7% to 17.3%), at the expense of some of the lower categories.
