Clean Energy Council (CEC) data has shown $2 billion worth of storage and hybrid projects have reached the investment stage in Q2.

The latest Renewable Projects Quarterly Report provides a detailed snapshot of Australia’s clean energy and storage investment pipeline. CEC chief executive Kane Thornton says that while an overall increase in investment activity during the quarter was encouraging, further action is required, citing a raft of barriers due to a “historic lack of leadership, planning and foresight over the prior decade”.

“These challenges make final investment decisions for large scale renewables projects more difficult and include under-investment in transmission, grid connection challenges, inconsistent planning policies, constraints in supply chains and workforce as Australia competes with global leaders that are all accelerating their demand for renewable energy,” Kane says.

“There is an enormous pipeline of renewable energy projects in Australia, but investors are swamped with global opportunity at a time when these barriers make Australian projects less attractive. The critical development needed to achieve 82% renewable generation by 2030 is not guaranteed unless we target the obstacles currently creating investment uncertainty for new energy generation.”

The data highlights of the report include battery storage projects leading the way for financial commitments during Q2 2023 with six projects totalling 3,802MWh added across Australia, breaking the billion-dollar barrier for the first time.

Furthermore, construction activity has been shown to remain strong as four generation projects commenced construction during the quarter, comprising an additional 1,172MW of capacity, while five projects reached the commissioning stage, contributing a total of 551MW.

Despite stronger results than during the previous quarter, new financial commitments in generation projects have also observed the slowest first half of a year since the Clean Energy Council began recording data in 2017. Four generation projects, totalling 348MW of generation capacity reached financial commitment.

Additionally, new financial commitments in large-scale generation during Q2 totalled 348MW worth $225 million, more than $1 billion (-82%) less than the rolling quarterly average over the last 12 months, which fell to $1.3 billion.

A total of four generation projects with 348 MW reached financial commitment during the quarter, the largest among them being the Ardandra Storage and Solar Project in Queensland.

While this quarterly result was an improvement on Q1, when there were no large-scale generation projects committed, investment levels so far this year are 50% below the rolling 12-month quarterly average of 699MW and are a long way off the pace necessary for Australia to achieve an 82% renewable energy share by 2030.

Looking further along the project pipeline, five generation and storage projects commenced construction in Q2. A total of nine projects reached the final commissioned stage in Q2, totalling $1.3 billion worth of investment.
