The economical benefit resulting from the reduction of variable cost can be estimated at EUR 72 million if nuclear production were replaced by coal, and EUR 245 million if replaced by gas.20 This corresponds to a yearly benefit of EUR 0.07 and EUR 0.25/MWh, respectively. However, this last consideration applies only to a situation in which nuclear energy is often at margins and is therefore peculiar to countries with a large share of nuclear power. Table 3.6 summarises the results for the 2007-2009 period.
