Load factors by utility to end June 2013

摘要

In the 12 months to the end of June 2013, data were available for 404 reactors rated at least 150 MWe gross which together generated about 2329 TWh of electricity. Combined total generation was down around 2% on the equivalent period the in 2011/12 period and 10% on the same period in 2010/11, principally due to the sustained closures of reactors in Japan. The average load factor of the operating reactors over the 12 months to end June 2013 was 67.7%, compared with 72.5% for 2011/12. For pressurized water reactors (263 units) the average load factor was 72.3%; boiling water reactors (83 units), 57.0%; pressurized heavy water reactors (45 units), 75.0% and RBMK (11 units) 81.0%. One magnox reactor was also in operation (Wylfa 1, UK), together with one fast breeder reactor (Beloyarsk 3) in Russia.
