What is D2E repowering?
Diesel-to-Electric (D2E) repowering converts an existing diesel truck into a full battery electric vehicle (BEV) by:
- Removing the internal combustion engine (ICE), fuel system, exhaust system, and transmission
- Replacing them with a fully electric drivetrain, battery packs, and an electric motor
Significant reduction of Total Cost of Operation
2E Repowering allows fleets to capture the benefits of electric trucks at a lower capital expense.
Operational expenses as energy cost and traffic charges are drastically reduced
Repowering: A New Life for Your Truck
Repowering transforms a diesel truck into a fully electric vehicle, delivering:
- Higher energy efficiency: 1,1 kWh/km for a Battery Electric Truck vs 3 kWh/km for a diesel truck
- Potential for full renewable energy
- Zero emissions: CO2, NOx, SOx, particulates
- Significantly reduced road taxes
- Lower maintenance costs, roughly half
- Extended operational life,
At the heart of our approach is the circular economy — giving your existing asset a second life instead of replacing it.
The retrofit process upgrades the truck’s systems while preserving key components like the original chassis, axles, cabin, brakes, suspension, and steering — ensuring maximum reliability and sustainability.
Our Mission
"TROVA accelerates the shift to sustainable transportation through diesel-to-electric truck repowering."
"We support a circular economy and renewable energy use, while facilitating an economic efficient logistics industry through cost reduction.”

Environmental Regulations
Governments are imposing stricter environmental regulations to reduce air pollution and greenhouse gas emissions. Many cities are implementing Low Emission Zones (LEZ) and plan to ban Diesel vehicles.
Why should you repower your trucks?
Modernisation without full replacement
Retrofit allows companies to upgrade their existing fleet without purchasing entirely new vehicles, which are up to 50% more expensive. New electric trucks have delivery times of 12-18 months.
Corporate Social Responsibility (CSR)
Many companies have sustainability or carbon reduction goals as part of their corporate strategy (ESG). Repowering to electric trucks helps to meet these targets because of its circular economy nature.
Energy Cost savings
Battery Electric Trucks (BET) are with 1,1 kWh/km superior in energy efficiency vs a diesel truck (3 kWh/km). In addition diesel cost is increasing and ETS2 will add to its cost.The energy cost of an electric truck is about half of that of a diesel truck.
The cost of electricity is indeed dependent on multiple parameters (sun, wind, time of day, gas,...) in which Energy Management systems can lead to cost saving
Access to incentives & subsidies
Zero emission trucks have a significantly lower road tax. Some governments offer financial incentives to facilitate the energy transition.
Reduced maintenance costs
Electric drivetrains have fewer moving parts compared to diesel engines, which translates to lower maintenance requirements. There is no need to change oil, exhaust system repairs, or engine related maintenance that come with a diesel vehicle.
