Queensland managed to evade power blackouts on Monday night but is being warned of more potential power shortfalls coming.
The Australian Energy Market Operator (AEMO) had earlier issued a forecast that demand could outstrip supply for Monday afternoon and evening, but shortfalls were averted.
But AEMO issued a statement saying it had invoked its powers under the National Electricity Rules and the efforts “provided sufficient generation to cover the lack of reserve 3 shortfall.”
Powerlink Queensland confirmed the winter heating and “unexpected generator outages” were contributing to power shortfalls.
The coming days for Queensland and New South Wales also have the potential for power supply reserve shortfalls occurring.
“Despite there being sufficient physical generation capacity in Queensland today, AEMO is taking steps to address a critical electricity supply shortfall presently forecast for 6pm to 8pm AEST today.” AEMO said in a statement.
“To maintain power system security and reliability, AEMO is using its powers under the national electricity rules, including to direct generators, to alleviate lack of reserve conditions.”
Powerlink Queensland said using less power during periods of potential electricity shortages may lessen the stress on the power system and ensure essential services and commercial businesses avoid losing power.
This includes considering the number of rooms that require heating and turning off TVs, computers, and other appliances not being used.
“By carefully managing electricity use at home and in your workplace, the community can help ensure that power system security is maintained in Queensland,” Powerlink chief executive Paul Simshauser said.
“We’re really only talking about two or three hours in the evening peak — so around about sort of 5:30pm to 8:30pm, and just in the morning.”
AEMO said it would continue to take actions in order “improve electricity reserves, including directing generators into the market, which helped meet electricity shortfalls in Queensland and New South Wales.”
