As electric trucks move from trials to early deployment, megawatt charging has quickly become the headline technology. Faster charging, shorter stops and higher utilisation sound like the obvious answer for freight operators under pressure to maintain productivity.
But according to industry practitioners working at the sharp end of heavy vehicle electrification, megawatt charging alone will not unlock mass adoption. The reality is more complex — and far more operational.
Faster charging doesn’t solve every problem
Megawatt Charging Systems (MCS) will play an important role in long-haul electric freight, particularly on major corridors such as the Hume Highway. However, the idea that megawatt chargers are the single missing piece is overly simplistic.
“Megawatt charging will absolutely play a role, but it won’t be the ubiquitous solution for everything.”
Rainer Knobloch, Chief Commercial Officer of NewVolt, says fleets need to look beyond charger power ratings and focus on how charging fits into real-world operations.
For many duty cycles, particularly urban and regional work, ultra-fast CCS charging at 500–700kW may be sufficient. The challenge is not just how fast a truck can charge, but when it charges, where it charges, and what that energy costs at that time.
Why CCS and megawatt charging will coexist
Rather than replacing existing standards, megawatt charging is expected to sit alongside high-power CCS.
“I don’t think CCS is dead. Ultra-fast CCS will creep up to six or seven hundred kilowatts, and that will be enough for a vast majority of duty cycles, particularly around cities.”
This has major implications for infrastructure planning. Fleets operating mixed routes may not need megawatt charging everywhere — but they do need reliable, accessible charging that aligns with shift patterns and delivery windows.
Energy cost matters more than charger size
One of the least understood aspects of electric freight is how sensitive operating costs are to electricity pricing.
Many heavy vehicles operate overnight, particularly on long-haul routes. That creates a mismatch between when trucks need energy and when renewable electricity is cheapest.
“If you’ve got significant excess solar in the middle of the day, how are you getting those cheap electrons into a truck when most of the charging needs to happen at night?”
This is where charging speed alone fails to solve the problem. Even a megawatt charger delivering power quickly can be expensive to run if electricity is being drawn at peak prices.
Battery storage is becoming central to the equation
Battery energy storage is increasingly seen as a key enabler — not just for grid stability, but for freight economics.
Falling battery costs are changing the viability of on-site storage, allowing operators to capture low-cost energy and deploy it later when trucks need it.
“The biggest thing we’re seeing is the collapse in battery prices. That changes the economics completely.”
NewVolt assesses charging economics using a combination of:
Levelised Cost of Energy (LCOE)
Levelised Cost of Storage (LCOS)
Levelised Cost of Charging (LCOC)
The interaction between these three factors often matters more than charger output alone, particularly for fleets operating on tight margins.
Deployment speed is just as important as power
Another shift underway is how charging infrastructure is deployed. Traditional projects often rely on major grid upgrades, long lead times and heavy capital investment.
New products and approaches are now emerging that reduce dependency on lengthy network upgrades, allowing sites to be deployed faster and more flexibly.
“Previously, you’d be waiting a long time for grid upgrades. Now we’re seeing products that can be deployed much more quickly, without that same level of upfront investment.”
Companies such as Kwetta and Virtos are among those rethinking how high-power charging can be delivered with less reliance on traditional grid expansion.
Lean sites before mega-hubs
Rather than building large, high-capacity charging hubs from day one, many operators are now considering leaner sites designed to unlock routes first and scale later.
“We probably don’t need giant sites on day one. We need leaner sites to unlock routes and work towards the techno-economics.”
This approach reduces risk, allows fleets to learn from real operations, and avoids over-investing before utilisation is proven.
Why collaboration matters
The emerging charging ecosystem for heavy vehicles will require coordination between fleets, infrastructure providers, energy companies and governments.
Programs such as Drive to Zero, led by CALSTART, are built around shared learning and collective problem-solving rather than isolated projects. In Australia, agencies such as Australian Renewable Energy Agency continue to support early-stage deployment, but the long-term goal is commercial viability without ongoing subsidy.
“This isn’t going to be solved by one party stepping up and doing everything. Everyone has to lean in.”
The real answer: systems, not silver bullets
Megawatt charging will be part of the future of electric trucking — but it is not the shortcut some hope it will be.
For fleets, success will depend on integrating charging speed, energy pricing, storage, route planning and operational timing into a single system. Those who focus only on charger size risk missing the bigger picture.
The fleets that move first will not be the ones chasing the biggest numbers on a specification sheet, but those that understand how to power trucks reliably, affordably and at scale.
