WA EV Network: Drivers Report Malfunctioning Chargers & Reliability Issues

As soaring fuel costs drive increased interest in electric vehicles (EVs), a critical piece of Western Australia’s infrastructure – its state government-owned charging network – is facing scrutiny. Despite being lauded as one of the world’s longest “electric highways,” recent reports suggest the network is struggling to deliver on its promise, leaving drivers with range anxiety, particularly those traversing the remote Nullarbor Plain.

Automakers and dealerships have reported a spike in electric and hybrid vehicle sales in Australia since the outbreak of the Iran war, further highlighting the importance of a reliable charging infrastructure. The WA EV Network, completed in June 2025 with 110 charging points across the state, even earned a spot on Time Magazine’s list of the world’s 100 greatest places to visit in 2024. Though, the reality on the ground appears to be far from the idyllic picture painted by these accolades.

Infrastructure Challenges on the Eyre Highway

The core of the problem lies in persistent malfunctions, limited charging speeds, and unreliable power supplies plaguing several stations along the Eyre Highway, the main route across the Nullarbor. Perth resident Chris Johnson, a member of the Australian Electric Vehicle Association (AEVA) committee, initially praised the network’s launch, noting an “overwhelmingly positive” response from EV drivers. Johnson himself had successfully driven from Perth to Sydney several times since 2023, initially relying on a network of crowdfunded chargers before the WA EV Network’s expansion.

However, recent experiences have soured that initial optimism. Johnson now finds himself opting for flights rather than driving due to the uncertainty surrounding charger availability. He recounts a trip last June where the Madura Pass charging station on the Nullarbor was already malfunctioning, delivering only 11 kilowatts per hour instead of the expected 50. At the next station, Mundrabilla, the charger reportedly caused a blackout by overloading the roadhouse’s generator. These incidents are echoed by other EV drivers on the Plugshare EV map website, with many now advising to only use the slower AC charger at Mundrabilla.

The slower charging speeds create significant delays. Johnson cites one AEVA member taking 14 hours to travel between Eucla and Fraser Range – a journey that should typically take seven hours. This unreliability raises serious concerns about drivers becoming stranded along the remote route.

Power Supply and Network Design

The WA EV Network is a joint initiative between state government-owned enterprises Synergy and Horizon Power, representing a $43 million investment in EV charging infrastructure. Horizon Power is responsible for the more remote charging stations along the Eyre Highway. Ideally, DC chargers along this route should deliver 50 kilowatts per hour, allowing for a full charge in approximately one hour, depending on the vehicle type. Slower AC chargers are also available, but significantly extend charging times.

A key challenge is the reliance on off-grid chargers, which depend on standalone power systems or roadhouse generators. Retired mechanical engineer Jon Edwards, who built the first EV charger on the Eyre Highway in 2022 – powered by recycled chip frying oil from the Caiguna Roadhouse – highlighted the strain these chargers place on existing infrastructure. “The generators are running flat out, all the caravan park air conditioners are going flat out – they’re cooking tea, freezers doors are being opened and closed,” Edwards explained, emphasizing the limited capacity of these remote locations. He notes that the unreliability has led to many off-grid chargers having their power output reduced to slower charging speeds.

Government Response and Future Upgrades

WA Greens leader Brad Pettitt acknowledges the network’s initial promise but stresses the necessitate for ongoing maintenance and upgrades. He argues that the current issues leave EV drivers “stranded, or certainly having very long, slow trips.” Pettitt emphasizes that a network is only as strong as its weakest link.

In a statement, a Horizon Power spokesperson acknowledged that individual chargers may occasionally require maintenance, particularly given the challenging operating environment. They stated that the company works with charging operators and site hosts to address issues through established monitoring, maintenance, and escalation processes, using learnings to inform ongoing improvements. Energy Minister Amber Jade-Sanderson deferred comment to Horizon Power.

Implications for EV Adoption and Tourism

The problems with the WA EV Network have broader implications beyond individual travelers. The state government’s investment was intended to encourage EV adoption and position Western Australia as a leader in sustainable tourism. However, the current unreliability risks undermining these goals. Potential EV buyers may be deterred by range anxiety, while tourists may opt for other destinations with more dependable charging infrastructure. Here’s particularly concerning given the rising fuel prices, which are a key driver of interest in EVs.

The situation also highlights the complexities of building out charging infrastructure in remote areas. The need for robust power supplies, reliable maintenance, and careful network planning are crucial for ensuring a positive EV driving experience. The reliance on existing roadhouse infrastructure, while convenient, presents challenges in terms of capacity and stability.

What’s Next for the WA EV Network?

Horizon Power has not provided a specific timeline for addressing the identified issues. However, the company’s statement suggests a commitment to ongoing monitoring, maintenance, and improvements. Further investment in grid upgrades and alternative power sources, such as solar and battery storage, may be necessary to ensure the long-term reliability of the network. The state government will likely face increasing pressure to address these concerns as EV adoption continues to grow. The success of the WA EV Network – and the broader transition to electric vehicles in Western Australia – hinges on resolving these infrastructure challenges and restoring driver confidence.
