Expected ROI of MW scale storage system project in Australia 2025

Did Australia invest in energy storage projects in Q1 2025?

Australia's remarkable run of investment commitments to energy storage projects continued in Q1 2025. Six storage projects representing 1,510 MW (capacity) / 5,016 MWh (energy output) reached financial close – the second-highest quarterly result for newly financially committed storage projects.

How many storage projects are there in Australia?

There are also 69 committed storage projects (either standalone or hybrid projects) currently in this pipeline, equivalent to 12,532 MW / 32,078 MWh in capacity / energy output. Read the latest updates from the Clean Energy Council and across the industry. When it comes to Australia’s energy future, communities have legitimate questions.

How many battery storage projects commenced construction in 2025?

In addition to the six projects that reached financial commitment, a further three battery storage projects commenced construction in the first quarter of 2025, with a total of 840 MW / 2.9 GWh in storage capacity / energy output.

Will Australia's NEM see a massive increase in battery energy storage capacity?

Australia’s NEM will see a massive increase in grid-scale battery energy storage capacity in the next three years. There are 16.8 GW of battery projects that could come online in the National Electricity Market (NEM) by the end of 2027.

Why should Australia invest in energy storage systems?

Energy storage systems, such as big batteries, are a critical part of Australia’s future energy mix and act as a reliable back-up system allowing us to store renewable energy for when it is needed most and keep the lights on under all conditions. It’s great to see the high levels of investment we’ve seen over the past couple of years continue.

Will a new battery buildout increase battery capacity in Australia?

Even so, this buildout would result in a sevenfold increase in operational battery capacity over the next three years. Australia has a massive pipeline of grid-scale battery energy storage projects. 16.5 GW of new battery projects could arrive in the NEM in the next 3 years.
