Sydney-based electric trucking start-up New Energy Transport has secured a site for what will become Australia's largest heavy electric truck depot to date.

The company describes itself as a "new type of trucking enterprise" that operates a fleet of fully electric prime movers powered by wholesale renewable energy. It plans to establish a network of freight corridors connecting Sydney, Wollongong, and Canberra.

On Friday, New Energy Transport announced that it had acquired a site near Wilton, south-west of Sydney, which is expected to serve as a launch point for electric line-haul operations between Sydney and Melbourne.

"By combining low-cost renewable energy, high-speed charging, and electric prime movers, New Energy Transport offers zero-emission road freight at diesel-based prices," said Daniel Bleakley, Co-Chief Executive Officer of New Energy Transport and a former journalist.

Plans for the site have been endorsed by the NSW Member of Parliament for Wollondilly, Judy Hannan, who stated that the project would help reduce air and noise pollution, stimulate the local economy, and create long-term, high-quality employment opportunities.

"The testing of the trucks shows that there are alternatives which are not only better for the environment but also more beneficial for drivers and business owners," Hannan said. "I look forward to the next stages of the rollout and hope that Wollondilly will be part of this transformation within the industry."

By 2031, New Energy Transport aims to operate a fleet of more than 200 all-electric trucks serving Adelaide, Melbourne, Sydney, Canberra, and Brisbane.

The company also claims to have completed Australia's longest single-charge electric truck delivery - a 480-kilometre round trip transporting 36 tonnes from Picton, south of Sydney, to Beresfield in the Hunter region.

Compared with Multiquip's diesel-powered trucks, the Windrose electric truck reportedly completed the journey 40 minutes faster - a 12% time saving - due to its ability to maintain higher speeds on uphill sections where diesel trucks typically slow down.

According to Multiquip, its diesel trucks average 85 km/h on this route, while the Windrose electric truck achieved an average speed of 98 km/h, to the surprise of diesel drivers observing its performance.

"This is the longest single-charge electric trucking demonstration in Australia to date," Bleakley said. "The successful journey demonstrates that zero-emission road freight can be achieved in a cost-competitive manner while enhancing productivity and performance compared with diesel-based freight."
