Heat and LNG development pushes electricity demand to record high

Monday’s heat contributed to a new record in Queensland, with demand on the electricity transmission network reaching an all-time peak.

Demand on Powerlink Queensland’s network reached 9097MW at 5.30pm on Monday (February 1) – the highest on record and 206MW higher than the previous record set in 2010.

Powerlink chief executive Merryn York said strong demand from LNG processing facilities in the Surat Basin had a significant role to play in the record.

“The previous record demand on the transmission network of 8891MW in 2010 occurred before gas processing facilities were constructed in the Surat – in contrast to 2010, which included no LNG-related load, approximately 450MW of this record demand is powering the new LNG facilities in south-western Queensland,” Ms York said.

“The timing of the demand peak is also significant with the record set later in the day at 5.30pm. This change in timing is mainly due to the impacts of strong rooftop solar panel uptake across Queensland offsetting demand, which would previously have had to be supplied through the networks.”

“Queenslanders with solar panels use their own generation until the late afternoon and then return to the electricity supply network for electricity to run air conditioners and other appliances from the early evening onwards.

“We plan and operate the network to allow for these hot conditions, particularly around this time of year.”
