AGL, with project partners ElectraNet and WorleyParsons, are exploring large-scale energy storage in a new project.

The Energy Storage for Commercial Renewable Integration (ESCRI) project explored commercial frameworks that can be used to operate utility-scale storage within the National Electricity Market (NEM).

A new report examining the project’s findings and the commercial feasibility of large-scale grid-connected energy storage is now available.  

The report provides a comprehensive overview of the opportunities and challenges for utility-scale storage and will be a useful resource for informing future projects.

ARENA provided AGL with $445,846 in funding toward the $1,029,578 project to carry out the investigation with project partners ElectraNet and WorleyParsons.

A detailed business case was modelled around a 10 MW/20 MWh lithium-ion battery connected at the Dalrymple substation on the Yorke Peninsula in South Australia.

South Australia has the highest proportion of renewable energy generation in Australia, making it an ideal location for the investigation.

The storage technology examined is not currently commercial.

The analysis also found there are several potential revenue streams for utility-scale storage. Revenue is site specific and some revenue streams are traded off against others, making it difficult to capture the full value of each stream.

Utility-scale energy storage could ultimately enable more value to be achieved from solar and wind farms by supplying generation at times when demand is high.
