Energy prices in November fell significantly due to increased use of renewables, with average prices for major customers down by almost 30% on the previous month.
The Western Australian Government’s plan to exit state-owned coal by 2030 and deliver large-scale renewables will continue to increase renewable energy output and keep downward pressure on energy prices.
WA Premier Roger Cook said, “Becoming a renewable energy powerhouse underpins our plans to diversify our economy, ensuring it continues to be the strongest in the nation.
“My government is delivering record investment in our transmission infrastructure to connect households and businesses to cheaper renewable energy.”
Energy and Decarbonisation Minister Amber-Jade Sanderson said, “Renewable energy is the cheapest form of generation, and renewables and storage firmed by gas when needed is the least cost energy mix for households and businesses.
