The renewable energy transition in Australia has faced significant challenges, with a particular focus on the issue of connections and their impact on the overall pace of the shift towards renewables. The Australian Energy Market Operator (AEMO) provides valuable insights into the progress of renewable energy projects, highlighting the bottleneck caused by the lack of connections. This issue has led to a slowdown in the pipeline of renewables, despite the strong approval activity for new projects.
One of the key reasons for the dominance of batteries in the pipeline is Australia's lopsided transition, driven by household rooftops rather than utilities. This has resulted in a daily energy 'duck curve,' where electricity prices crash during the day, making batteries a more profitable venture for utilities. However, this situation is expected to change as investment shifts to chase more profitable opportunities, following the natural course of capitalism.
The Capacity Investment Scheme (CIS) has not effectively addressed the issue of underbid-generation projects, instead triggering a need for business model reworks or abandonment. The good news is that the storage boom will reduce gas's role in setting prices within the National Electricity Market (NEM), potentially leading to lower wholesale prices.
The connections problem is evident in the extended implementation times, which have reached two years. Despite a recent drop in completions, the pipeline remains reasonable, indicating that improvements are on the horizon as connections and firming power projects progress.
However, the overall transition is still significantly behind schedule. State governments are resorting to publicly subsidizing unprofitable coal-fired power to bridge the generation gap, highlighting the urgency of the situation. The author suggests that a carbon price and gas reservation policy could have prevented these issues, but the politicization of the transition has led to a complex web of problems.
The gas cartel is exacerbating the situation by spiking wholesale and retail electricity prices, which are mistakenly blamed on the transition. This has fueled community resistance and increased skepticism, further delaying the connections lag. The result is a 'half-pregnant' grid, producing large amounts of firmed renewable power at a decreasing cost, but not enough to phase out old coal power by projected deadlines.
The author argues against building obscenely expensive coal or nuclear power, both of which are slower and require public subsidies. Instead, they advocate for utility-scale solar plus battery as the 'killer app' of the transition, emphasizing the falling costs of batteries and the competitiveness of this technology. The solution, according to the author, lies in government acknowledgment of past mistakes, realistic deadline setting, and rebuilding political consensus for the transition.
Despite the challenges, the author remains optimistic about the future of renewable energy in Australia, but questions the likelihood of the government taking the necessary steps to address the issues.
