South West WA received 35 per cent of its power from renewable energy in October, up from 25 per cent a year ago, due to two new wind farms and continued installation of rooftop solar panels.
The new Yandin and Warradarge wind farms in the Mid-West pushed wind’s share of generation from 12 to 17 per cent, to overtake rooftop solar panels that rose from 13 to 16 per cent.
Collie’s coal-fired power stations produced 29 per cent of the power consumed on the South West Interconnected System in October 2020, a massive cut from 37 per cent in 2019.
Coal-fired output dropped by more than a fifth, an indication of the immense financial pressure facing the town’s two privately-owned coal mines and the Bluewaters Power station.
Gas is now the dominant fossil fuel burnt to generate power, with 35 per cent of the market, but still lost 2 per cent of the market year on year due to the surge in renewable energy.
The 212-megawatt Yandin wind farm has generated power since July.
Warradarge started in August but only connected its full 180 MW in late October, indicating that future years could see a more power generated by wind in October.
The data comes from OpenNEM, a platform that just extended its coverage to WA and, unlike market operator AEMO, includes generation from rooftop solar.
