Port's Electric Truck Trial Cuts Energy Costs by 60%, Maintenance by 30%

Patrick Terminals, one of Australia's largest port operators, has released results from a A$7 million trial of heavy-duty electric terminal trucks at its Fremantle container terminal in Western Australia, revealing compelling operational cost savings and emissions reductions that could accelerate the electrification of the nation's logistics sector. The trial, co-funded with A$2.5 million from the Australian Renewable Energy Agency (ARENA), replaced eight of the terminal's diesel tractor fleet with nine Terberg battery-electric terminal tractors—the extra unit provided for redundancy—operating around the clock in a real-world port environment. The results announced on 14 July 2026 show that electric trucks cut energy costs by 60% compared to diesel, though terminal manager Peter Chesi acknowledged this was 'somewhat offset by the price of electricity in WA and the diesel rebate.' Maintenance costs fell by 30%, a significant number for an industry where heavy-duty equipment downtime and servicing are major line items. Scope-one greenhouse gas emissions at the facility dropped by 15%, an immediate climate benefit. On the performance side, the electric tractors hauled loads of up to 65 tonnes with ease and recharged to 80% battery capacity in under one hour, matching the duty cycles required for continuous port operations. Driver acceptance was high, with operators reporting smoother and quieter rides—a factor that can improve safety and retention in a tight labour market. The trial's success comes amid a broader wave of heavy-duty electric vehicle adoption in Australia. Logistics majors Unilever, Linfox, and Woolworths have already added heavy electric trucks to their fleets, and Volvo has just launched the first locally manufactured electric prime movers. Together with the Patrick Terminals data, these developments suggest that the business case for electrifying freight transport is maturing rapidly, at least for short-haul and terminal operations where vehicles return to base frequently and charging infrastructure can be centralized. However, the trial also surfaced challenges. Western Australia's electricity grid, still heavily reliant on fossil fuels, means the carbon intensity of the electricity used for charging tempers the net climate gain unless renewables are scaled concurrently. Additionally, the diesel fuel tax rebate—a politically sensitive subsidy—dulls the relative economic advantage of electricity. Despite the promising results, Patrick Terminals has not committed to purchasing additional electric trucks, remaining in what Chesi calls a 'discovery phase.' The caution reflects the pragmatic approach typical of major capital-intensive operators: they will watch how the technology, grid, and regulatory environment evolve before scaling up. Yet the trial provides a clear template. The Fremantle experience demonstrates that electric terminal tractors are technologically viable for heavy port logistics, having withstood the rigours of 24/7 operation without reliability issues. The performance data—65-tonne tow capacity, sub-hour fast charging, significant cost reductions—gives ammunition to procurement managers in other ports and freight hubs to push for electrification mandates. For ARENA, the outcome validates its mission to de-risk clean technology adoption in hard-to-abate sectors. Looking ahead, the most immediate impact may be the signalling effect: if a cautious operator like Patrick Terminals can achieve a 60% energy cost reduction, the total cost of ownership case for electric port equipment becomes harder to ignore. The next 12–18 months will test whether other terminals follow suit, and whether governments address the diesel rebate distortion. As battery costs continue to decline and fast-charging technology improves, the economics will only become more favourable. The Fremantle trial may well be remembered as the point where Australian port electrification shifted from pilot to pathway.
