Gas No Panacea For Australia's Rising Electricity Prices
Contrary to popular belief, a heavy reliance on natural gas for electricity
generation in Australia could see power prices soar - the key to reining in
electricity costs is renewable energy.
According to AECOM's senior consultant in Energy Strategic Advisory, Dr Jenny Riesz,
Australia's growing participation international gas markets could increasingly
expose it to associated price volatility, in the same way our petrol prices are linked to global fuel
"In addition, because these markets comprise long lived assets with long
development timeframes, any exposure of consumers to high electricity prices
would likely occur for an extended period of time until more competitive
generation assets were developed and implemented," said Dr Riesz;
co-author of a recently released paper titled "Delivering Energy Price
Security In An Age Of Uncertainty".
Another risk factor associated with international gas markets is their vulnerability
related to threats to infrastructure from natural disasters and geo-political
Dr Riesz says Australia has an opportunity to recognise the potential threat to
our energy price security and learn from international experience. She believes
increased focus on Australia's Renewable
(RET) is key.
"By achieving the RET through developing wind and other renewable energy
sources, Australia would essentially be investing in a diverse generation
portfolio and reducing the risks associated with its gas market, such as
international price influences."
Dr Riesz points out that at gas prices of $11-$12 a gigajoule (GJ), wind generation becomes competitive with a combined cycle gas turbine (CCGT), even
without a carbon price and RET support. With a carbon price of $23 a tonne, wind competes at only
"Similarly, recent and continued cost reductions in solar photovoltaics put this technology at only a small additional cost."
