The NT government has announced the Wurrumiyanga Solar Infill and Energy Storage Pilot Project is closer to completion, with the battery energy storage system currently being tested in Berrimah.

Wurrumiyanga, a community on the southern coast of Bathurst Island, already oprates on some solar, however the project will provide an additional 1.1 megawatt solar array, together with a 1.75 MVA battery energy storage system. The battery itself will provide 3 megawatt hours of storage capacity.

Tiwi MP Manuel Brown, whose electorate of Arafura covers Wurrumiyanga, said it was great to see the largest community on Bathurst Island driving down emissions.

"Testing underway means my community will get more renewable energy soon," the MP said.

"A renewables future is now one step closer for the Wurrumiyanga community and we look forward to extending the lessons learnt from this project to other remote Territory communities."

The government has said the battery system will be transported to Wurrumiyanga once testing is complete, before another round of testing will take place to ensure it integrates successfully with the local power grid.

"The project is estimated to reduce diesel fuel consumption by 519,000 litres in the first year of operation by introducing additional renewable energy technology, with works expected to be completed by May 2024," the government said.

Renewables Minister Energy Kate Worden said the NT was in the process of transitioning to a "future where renewable energy will play a greater role in our energy consumption" as they work towards net zero emissions by 2050.

"The Wurrumiyanga Solar Infill and Energy Storage Pilot Project will give the community cleaner power and reduce the need to rely on diesel generators," Minister Worden said.

The NT government has a target of 50 per cent renewable energy by 2030. This includes an average of 70 per cent renewables in all communities supplied by the Indigenous Essential Services program.
