Renewable energy supplied 21.7 per cent of grid energy in October, the highest figure since complete National Electricity Market data became available, according to the latest pitt&sherry CEDEX report.

The penetration of renewables for the year now stands at 14.7 per cent, the highest proportion since 1982 when electricity demand was half of what it is now and hydro power accounted for practically all renewable energy. Record wind and hydro power meant their contribution to the grid was just 63 gigawatt-hours (or 0.4 per cent of total generation) less than brown coal.

Total emissions also fell by 0.8 per cent over the past year, thanks to a fall in both black and brown coal generation, and gas generation, which were pushed out by the increases in renewables. Emissions were at their lowest levels in over a year, which the report said demonstrated “how quickly and effectively emissions could be reduced by increasing the share of renewable generation”. Emissions, however, were still four per cent higher than the year to 2014.

Wind power set new records, both in absolute and relative terms, supplying 6.4 per cent of total generation for the month.

Demand was stable, with a decrease of just 0.07 per cent.
