Fossil fuel generation in the UK fell to record lows last month, while renewables provided a quarter of all electricity, turning August into “the cleanest calendar month of the year in modern times” according to energy experts at consultancy EnAppSys.
The firm’s senior analyst Rob Lalor said generation from fossil fuels amounted to just 8.7TWh last month, only marginally higher than the 8.6TWh posted in August 2017. He said these figures represent the lowest levels of fossil fuel generation in a single calendar month since the Second World War.
“For the second August running, the GB power market has seen record low levels of fossil fuel generation driven by low demand for electricity and growth in levels of renewable generation. This occurred despite reduced levels of nuclear and wind generation in 2018,” said Lalor.
While Lalor said that the summer months typically see lower levels of electricity demand against the levels seen across winter, “rising levels of renewables in the summer months have been key to reductions in emissions over time”.
“Levels of wind generation are typically far higher during winter months, but solar generation will peak during the sunniest periods of the year. This offers a complementary balance between the fuel types and although last month levels of renewable generation were down 31 per cent from the 12-month high, renewables still provided a quarter of all generation.”
