In 2008, German nuclear power plants increased their gross electricity production by 5.9 percent. Production rose from 140.5 billion kilowatt hours (billion kWh) in 2007 to 148.4 billion kWh last year. Top of the table was the Isar 2 nuclear power plant in Bavaria with an annual production of 12.1 billion kWh with an output of 1,475 megawatts (MWe). To a large extent, this significant productivity increase in the German nuclear energy economy is also attributable to electricity production in the nuclear power plants in Hesse where Biblis A produced 9 billion kWh and Biblis B 11 billion kWh. Following refurbishment and inspection measures, Block B went back online in December 2007 and Block A in February 2008. Last year the two blocks achieved the best result in their operating history. In December 2008, Biblis B reached a further milestone when the power plant block exceeded the production mark of 250 billion kilowatt hours.
According to the most recent data available from the Working Group on Energy Balances, the share of nuclear power in primary energy consumption in Germany rose from 11.1 percent in 2007 to 11.5 percent in 2008. In relation to the total primary energy consumption of 480 million tonnes of coal equivalents (million t SKE) last year, electricity production from nuclear power plants increased by 5.7 percent to 55.3 million t SKE.
Once again the figures support the outstanding contribution of CO2-free electricity production from nuclear power to Germany`s security of supply and its efforts regarding climate protection.
