We understand that the security of electricity supply is vital to our customers, particularly over Summer when energy use is at its peak.

Our energy portfolio is a mix of coal, gas and renewable energy assets. These assets produce energy that feeds into the National Energy Market, but the energy landscape has changed in recent years with the Summer peak being even more important to our customers.

How does AGL’s generation fleet contribute meeting peak demand?


Working together as a portfolio is key to meeting peak demand.

Our coal-fired power stations provide the baseload generation while our gas and renewable assets are smaller and more agile, so can help us to meet high demand during peak periods like Summer.

Recent upgrades on site


AGL invests a significant amount of funds to maintain our plants and keep them running reliably to meet our customers’ needs.

We've stepped-up planned maintenance at all our sites to improve safety and reliability and we’re continuing to invest in gas and renewables to increase our ability to rapidly dispatch more energy into the network.

Here is some of the work we’ve been doing…

  • Upgrade coal dredgers at the Loy Yang mine. The mine provides coal to Loy Yang A and Alinta’s Loy Yang B power station, which generate a combined 50% of Victoria’s electricity requirements and feed into the national grid.
  • Installation of a new control system on Unit 1 at Bayswater to improve plant stability, operational flexibility and reliability.
  • Additional maintenance work is scheduled for Torrens Island Power Station after the Summer peak period.
  • A recently approved $25 million upgrade to Loy Yang’s Unit 2 – increasing the capacity by 15 MW, but not coal consumption or emissions, ensures Loy Yang remains a safe, reliable and competitive supplier to the NEM.
  • A new titanium condenser at Loy Yang Unit 4, helping to keep the unit on full load, even on the hottest summer days.
  • And we’re rewarding NSW customers for reducing their energy use during peak times. The Peak Energy Rewards Program aims to deliver an additional 20 MW, enough to power more than 3,000 houses, by offering financial incentive to registered customers to voluntarily switch off appliances at peak times.
