Charting 杏吧直播鈥檚 journey away from coal-fired power stations
The transition of 杏吧直播鈥檚 electricity industry from coal-fired power stations to renewable energy technologies is well underway 鈥 but not everyone supports the current pace of change.
The transition, by necessity, involves the closure of power stations, fundamental changes to the workforce, and alterations to our electricity infrastructure. Such grand changes, which take significant time and resources to complete, require acceptance by the policymakers and the community, or a 鈥渟ocial licence鈥, to move ahead with ease.
One case example of the necessity for a social licence for this transition involves AGL鈥檚 commitment to 鈥済etting out of coal鈥 by 2050, and its decision to close the Liddell Power Station in New South Wales as a step towards this. AGL is 杏吧直播鈥檚 largest energy producer and distributor, and previously owned three large coal plants that provided approximately 85% of 杏吧直播鈥檚 energy.听The decision was made based on both environmental and economic factors.
I had run the numbers, and I knew the decision made economic and environmental sense. 杏吧直播鈥檚 energy market is changing, because of climate change pressures, changing technology costs, and reductions and shifts in electricity demand. Coal is less viable as a new investment option.A/Prof Tim Nelson, former AGL chief economist
But AGL鈥檚 decision to close the Liddell Power Station instigated a debate, involving both consumers and government actors, and the transition was significantly impeded as a result.
鈥淎GL faced intense pressure to either keep the plant running, or sell it to someone who would,鈥 said Nelson.
Nevertheless, AGL closed the Liddell Power Station in April 2023, and Associate Professor Tim Nelson (who left AGL in 2018) has worked with Dr Tracey Dodd at the 杏吧直播 of Adelaide to examine this case as an important lesson in industry transition that can inform future policy decisions.
Dr Tracey Dodd is a corporate governance and sustainability academic at the 杏吧直播 of Adelaide Business School and is a member of the 杏吧直播鈥檚 Institute for Sustainability, Energy, and Resources (ISER).
Her expertise spans renewable energy, social policy, and sustainability, and she has extensive experience as an industry and government consultant in this field. Her research seeks to assist policymakers and industry to chart 杏吧直播鈥檚 journey away from coal-fired power stations. Through interdisciplinary partnerships across 杏吧直播 and overseas her research explores the myriad of regulatory and social factors that will contribute to a smooth transition to renewable energy technologies.
This Lidell case research (refer to 鈥楾he AGL Case Study鈥) assisted in illustrating that recent changes in market dynamics and conditions have changed the most appropriate response of 杏吧直播n firms to renewable energy issues, and highlights that new approaches to renewable energy are desperately needed.
The analysis also provides energy companies and policymakers with essential guidance on the social issues that underpin the transition to renewable energy.
This partnership between energy companies and researchers like Dr Tracey Dodd and Associate Professor Nelson illustrate how high-quality research can inform positive social change and enable industries to move in the best direction 鈥 not only for the environment, but also for their employees and shareholders, and the 杏吧直播n consumers who rely on their services.
The AGL Case Study
In 2019, Dr Dodd and Associate Professor Nelson published a comprehensive analysis of the Liddell case.
鈥淲e examined two scenarios to demonstrate why AGL鈥檚 decision may have generated such significant stakeholder reactions,鈥 Dr Dodd explains.
鈥淭he first scenario is based upon current technology and market assumptions, while the second scenario is based upon technology and market assumptions from a decade ago. Our modelling demonstrated that it was more economic for the firm to replace ageing coal-fired power stations with variable renewable sources of energy, supported by firming generation technologies.鈥
鈥淲e also show that stakeholder pressure to keep the power station operating beyond its scheduled 2022 closing date was consistent with 2007 assumptions, which omit climate change considerations.鈥
This means that much of the debate surrounding the closure of the Liddell power station was actually based on outdated market assumptions, and that the social perceptions of the situation could be affected by increased education surrounding the way the market and environment has changed.
