Conversion to electric as a strategic decision to reduce overall fleet costs
Up to 425 km of range after an upgrade to electric and without the cost of a new vehicle? Upfitting to electric is your strategic decision to reduce total fleet costs and comply with climate regulations. The federal government supported this step until 2024 with a subsidy rate of up to 80% of the additional costs – no new funding calls are planned.
The topic briefly and concisely
The conversion to electric reduces the total cost of ownership (TCO) for fleets due to lower energy and maintenance costs as well as tax benefits.
State subsidies (KsNI) covered up to 80% of the additional costs of a conversion; the program ran until 2024, and new funding calls are not planned.
The continued use of existing vehicles through a diesel-to-electric conversion (DTE) is an active contribution to the circular economy and reduces the CO₂ footprint.
Rising diesel prices, increasing regulatory pressure from the Clean Vehicles Directive, and high CO₂ levies are burdening the budgets of fleet operators. Many feel forced to choose between expensive new vehicles and uncertain residual values of their existing fleet. But there is a third, economically superior option: converting to electric as a strategic decision to reduce total fleet costs. This approach, also known as DTE, not only preserves the value of your proven vehicles but also significantly reduces operating costs. Based on a clear analysis of the Total Cost of Ownership (TCO), we show you how to shape this transition pragmatically and realistically assess the available subsidies.
Why electrification is now an inevitable strategic decision
In view of CO₂ taxes and the German implementation of the Clean Vehicles Directive (CVD), inaction is becoming expensive for fleet operators. Since 2021, the CVD has already prescribed binding minimum quotas for clean vehicles in public tenders, which have been tightened further since 2026. A perspective focused purely on the purchase price falls short here. The decisive key figure is the total cost of ownership (TCO), which includes all expenses over the entire lifespan of a vehicle. A conversion reduces these costs by up to 40% through savings in energy, maintenance, and taxes. The KsNI funding directive of the Federal Ministry for Digital and Transport (BMDV) supported conversions until 2024 with up to 80% of the additional costs, making the decision even more economical. With the right analysis of the total fleet costs, the transition becomes plannable and profitable. This strategic step not only secures your competitiveness, but also prepares your fleet for a locally emission-free future.
Your 4-point plan to reduce fleet costs through electrification
A successful transition requires a pragmatic and structured approach. With this four-step checklist, the conversion to electric becomes a plannable strategic decision.
Inventory and requirements analysis: Precisely record the daily mileages and typical routes of your fleet. This data forms the basis for configuring the optimal battery size and range, for example up to 425 km for a converted Sprinter.
Perform TCO comparison: Compare the total lifecycle costs of your current diesel vehicles with the projected costs after conversion. Take into account energy prices, maintenance, taxes, tolls and the annual income from the GHG quota of up to €6,950 for an N3 vehicle.
Check funding opportunities: Identify all relevant funding pools. The BMDV's KsNI guideline offered up to 80% subsidies for vehicle conversion until 2024 and included the development of the necessary charging infrastructure.
Plan implementation and charging infrastructure: Coordinate your conversion slots early; no new funding calls from the KsNI are planned. In parallel, plan the development of the charging infrastructure, which ensures the operational readiness of your fleet with up to 165 kW DC fast charging.
Each of these steps helps to make the amortization calculation for your fleet transparent and to minimize risks. In this way, the transformation becomes a calculable success.
The facts: TCO benefits of a diesel-to-electric conversion in detail
Lower operating costs as the primary driver
The greatest leverage for reducing TCO lies in running costs. Electricity costs per kilometer are significantly lower and, above all, more stable compared to diesel. An electric drive also has up to 90% fewer moving parts than an internal combustion engine, which drastically reduces maintenance requirements. Oil changes, exhaust system repairs, and clutch wear are completely eliminated, reducing service costs by up to 40%. Added to this are financial advantages such as exemption from vehicle tax for ten years and significant savings on the truck toll. These combined savings mean that the investment in a conversion often pays for itself after just three to five years.
Additional income through the GHG quota
Every electrified commercial vehicle generates additional annual income through the sale of the greenhouse gas reduction quota (GHG quota). As an owner, you can have the saved CO₂ emissions certified and sell them to companies subject to quota obligations. For a light e-transporter (class N1), this can be up to 625 euros per year; for heavy trucks, the revenues increase significantly. This income further improves the TCO balance and accelerates the amortization of your investment. With professional assertion of the GHG quota, you can exploit this potential without any administrative effort. The conversion is therefore not only a cost saving, but also becomes a new source of income.
Government subsidies as leverage: Up to 80% subsidy was available until 2024
The Federal Government accelerated the transport transition with subsidies that turned the conversion to electric into a profitable strategic decision. The central instrument was the BMDV's funding guideline "Climate-friendly Commercial Vehicles and Infrastructure" (KsNI).
80% subsidy for vehicle conversion: Until 2024, the state covered up to 80% of the additional costs incurred by electrifying a diesel vehicle compared to a conventional new vehicle.
40% subsidy for charging infrastructure: The construction of the necessary charging infrastructure on company premises was also supported with 40% of the investment costs.
Funding for feasibility studies: Even the analysis of the fleet's electrification potential was eligible for funding.
Important: The KsNI guideline ran until 2024, and no new funding calls are planned. For open programs, it is advisable to start the process early. A conversion instead of a new purchase was the most economical option thanks to this funding. The combination of falling operating costs and a circular economy remains a reliable foundation for setting the course for the future.
More than just costs: Sustainability and circular economy as a strategic advantage
The conversion to electric is more than just financial optimization; it is a clear commitment to sustainability. By converting your existing vehicles instead of buying new ones, you act in the spirit of the circular economy. You extend the lifespan of a proven chassis by many years and avoid the CO₂ emissions and resource consumption associated with the production of a completely new vehicle. This reduces your company's CO₂ footprint in two ways: in operation and in procurement. A converted vehicle saves several tons of CO₂ over its second half of life. This demonstrable sustainability performance strengthens your brand with customers and partners and helps in fulfilling ESG criteria (Environmental, Social, and Governance). If you continue to use the existing fleet, you position your company as a responsible pioneer. In this way, electrification becomes an integral part of your future strategy.
Practicality in focus: mastering range and charging infrastructure
Ranges for every area of application
The concern about insufficient range is unfounded with modern electric commercial vehicles. HEERO offers the right solution for every requirement profile. The HEERO eTransporter achieves up to 500 kilometers with one battery charge. A Sprinter offers a practical range of up to 425 kilometers. Even special vehicles such as the low-floor or low-entry bus can cover up to 300 kilometers and thus easily cover typical daily routes in regular or shuttle services. The tourer for nine people even achieves a range of up to 400 kilometers.
Setting up an intelligent charging infrastructure
An efficient charging infrastructure is the backbone of every electric fleet. HEERO vehicles support DC fast charging with up to 135 kW, the low-floor bus even with up to 165 kW. This means a battery can be recharged to 80% of its capacity in around 45 minutes. We support you in planning and implementing the right charging solution directly at your depot. In the past, the investment was additionally facilitated by government funding programs. Well-thought-out charging and route planning ensures maximum vehicle availability and gives you planning security for the next ten years. This makes the transition to electromobility not only strategically wise, but also absolutely reliable in day-to-day operations.
