2023 was the year of the Big Battery

2023 was the year of the Big Battery. 1GW/1.5GWh of projects energized in 2023 (for projects over 1MW).

Not only was it a record-breaking year, Big Battery deployment smashed previous records. Twice as much capacity was energized in 2023 than in our previous best year (2021).

The figures signal the coming of age of the Big Battery. Clearly the deployment volume is at a new level. But it’s the number of projects being energized that has stepped up to a new level.

Only two projects over 100MWh were energized in 2021, with one (the Victorian Big Battery) made up more than half of 2021’s tally. In 2023 there were eight projects over 100MWh, four of which were over 200MWh.

What’s under construction confirms 2023 as a turning point for the Big Battery. 5GW / 12GWh of is currently under construction, and that’s just counting projects over 50MW. That is 6x the amount that was under construction at the same time last year.

What’s being built is larger again – 72% of the volume is from projects exceeding 500MWh. It’s not only larger, it’s longer: currently operating projects 200-500MWh in size have a weighted average storage duration of 1.5 hours; projects currently under construction of the same capacity have 2 hours storage duration. The bigger projects, those over 500MWh, are longer again (2.8 hour weighted average).

Those mega projects deserve their own colour. Here’s where you’ll find them.

The Big Battery may have come of age, but it’s got some rapid growing to do from here. SunWiz is tracking 168GWh of projects that could see the light of day.

Much more information on Big Batteries is contained in the 2024 SunWiz Annual Battery Market Report. See https://www.sunwiz.com.au/battery-market-report-australia-2024/ to download a sample.

SunWiz wishes to note its grid-scale market size research is based upon multiple datasources, many of whom deserve acknowledgement for their contribution to our industry: in particular RenewEconomy, AltEnergy, and Anero.id.

Interval Meter Data Tool Disclaimer

The Interval Meter Data Tool is designed to convert standard form meter data for the OpenSolar platform.

Users are responsible for meeting the requirements of the data that needs to be uploaded to the tool, which extends to but is not limited to

The completeness and accuracy of the data
Ensuring that there are no missing records
Uploading the data in one of the compatible intervals (15m, 30m or 1h).

Data uploaded to the Interval Meter Data Tool should not contain multiple datasets. In the case an excel file is uploaded, only the first sheet will be considered.

The accuracy of the output is dependent on the user’s dataset, therefore SunWiz does not guarantee the accuracy of the output.

The user must acknowledge that the output of the tool is beyond the control of SunWiz, and they must ensure that the data is accurate on their own behalf.

In the event that the program runs into an issue, the user will be issued with warnings or solutions to address or resolve the issue.

If the user requires additional support, they can avail it as a separate service from SunWiz

Warranties on performance

The Interval Meter Data tool from SunWiz attempts to convert most frequently occurring types of standard meter data file types in specific formats for the purpose of being used on the OpenSolar platform. Unless mentioned otherwise, SunWiz does not extend any guarantee of any kind, either expressed or implied, on the limited success of the Interval Meter Data Tool and the extent of it’s automation. Depending on the user’s upload, the program may require additional inputs, the training for which is not included in the purchase of this service and can be purchased separately.

Input requirements

The Interval Meter Data Tool accepts data in the 15-minute, 30-minute and 60-minute(hourly) intervals. In case the file is uploaded in an excel format (*.xls, *.xlsx, *.xlsm), only the first sheet of the file will be considered. Our tool is required to accept raw meter data, usually highlighted as ‘E’ data in its standard format; and therefore SunWiz does not guarantee that all data formats will be accepted.

For complete automation, the file must adhere to an acceptable standard format. In the case of an issue, the user will be provided with instructions by the tool on how it can be resolved. Warnings will be issued if the data is incompatible, incomplete with missing records and if multiple datasets are uploaded at once.
