One of Peter Dutton’s key selling points for nuclear power, its “always on” reliable generation of electricity, has been put to the test in a new analysis, which found that a fleet of modern nuclear plants is, on balance, about as reliable as a fleet of wind and solar farms – if those wind and solar farms were in the midst of a very bad renewable energy drought.
The analysis by David Osmond, a senior wind engineer who runs weekly simulations of Australia’s main electricity grid, compared outages experienced by solar and wind during renewables droughts – known as “dunkelflaute” – to outages in nuclear energy generators.
For the renewable energy side of the equation, Osmond draws on Griffith University modelling of 42 years of synthetic wind and solar data quantifying the risk of renewable energy droughts to Australia’s future energy supply.
The nuclear side of the equation is based on Osmond’s own analysis of seven years of daily nuclear fleet data since 2018 from European countries with four or more reactors.
Noting there has been more investigation into renewable droughts and the reliability of solar and wind in Australia than nuclear, Osmond sought to examine the “worst case scenario” for nuclear – periods with simultaneous issues with multiple reactors.
