Renewable Energy Hits Spring Record on SWIS

  • WA becoming a renewable energy powerhouse with new generation record
  • Renewables account for 55.78% of energy on the South West Interconnected System in November
  • First time that renewable energy has provided a majority of energy used by households and industry

The Cook Government's drive to make Western Australia a renewable energy powerhouse is setting records, with more than half the power used in November coming from renewable energy.

The South West Interconnected System (SWIS) reached a record 55.78 per cent renewable energy contribution in November, eclipsing the previous record of 49 per cent, set in November 2024.

Energy prices in November fell significantly due to increased use of renewables, with average prices for major customers down by almost 30 per cent on the previous month.

The Cook 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.

The Clean Energy Link program to expand and upgrade the SWIS transmission grid will unlock more renewable energy resources.

The Government's Residential Battery Scheme is enabling households to benefit further from the State's clean energy transition, through rebates and no-interest loans to install solar panels and batteries.

The scheme delivers important cost of living relief by enabling households to store and use more of their solar energy, driving down power bills.

The scheme will enable 100,000 households to gain the benefits of solar energy.

As stated by Premier Roger Cook:

"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."

As stated by Energy and Decarbonisation Minister Amber-Jade Sanderson:

"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.

"The latest renewable generation figures and average energy price for November show what can be achieved as more renewable energy generation enters our power grid.

"We are unlocking more renewable energy through transmission infrastructure upgrades and expansion, which will continue to put downward pressure on prices."
