Your Bus Electric Network: Reduce TCO with 80% funding and set the course by 2025
Already over 3,500 eBuses are receiving an 80% subsidy – when will you electrify your fleet? Transitioning to a comprehensive electric bus network is inevitable, yet high costs and bureaucracy hamper many fleet operators. Act now before the current funding period ends.
The topic briefly and concisely
The BMDV subsidy offers an 80% grant for e-buses and DTE conversions, as well as 40% for charging infrastructure, but applications must be submitted by 31 August 2025.
The EU directive 'Clean Vehicles Directive' creates legal pressure for conversion, as it mandates increasing minimum quotas for zero-emission vehicles in public procurement.
The Diesel-to-Electric conversion (DTE) reduces the Total Cost of Ownership (TCO) through lower investment, energy, and maintenance costs, offering a sustainable alternative to purchasing new vehicles.
Rising diesel prices, strict EU regulations, and the pressure to reduce CO₂ emissions pose significant challenges for fleet operators. Building a high-performance electric bus network is the strategic response to these challenges. It involves more than just replacing vehicles; it requires a thoughtful restructuring of your operational processes. The current funding guideline from the Federal Ministry for Digital and Transport (BMDV) offers a unique opportunity: up to 80% subsidy for vehicle procurement or conversion and 40% for charging infrastructure. However, the application deadline is 31 August 2025. This guide illustrates in four clear steps how to maximise this funding and significantly reduce the Total Cost of Ownership (TCO) of your fleet.
The Facts: Why Now is the Right Time for Electrification
Electrifying your bus fleet is no longer an option, but a business and regulatory necessity. The conditions in 2025 are more favourable than ever before, but require swift action.
Here are the four crucial facts for your planning:
80% investment subsidy: The BMDV supports the acquisition of new electric buses as well as the Diesel-to-Electric (DTE) conversion with up to 80% of the additional costs compared to a diesel counterpart.
40% for charging infrastructure: The establishment of the necessary charging infrastructure, from the wall box to the DC fast charging point, is subsidised with up to 40% of the investment costs.
Deadline 31 August 2025: All project outlines for the current funding round must be submitted by this date to be considered.
EU pressure through the Clean Vehicles Directive: This EU directive requires public contracting authorities to meet fixed quotas for emission-free vehicles, which will be further tightened from 2026.
This constellation of high subsidy and impending deadline creates an urgency that must be strategically utilised. The next step is a clear action plan.
Your 4-Point Action Plan for a Profitable E-Bus Network
A successful bus electric network does not happen by chance, but through a structured process. With this checklist, you ensure that you take advantage of all opportunities and minimise risks.
Follow these four steps to timely implementation:
Conduct fleet and needs analysis: Analyse your current routes and operating costs. A detailed Total-Cost-of-Ownership calculation shows for which vehicles a conversion with up to 425 km range is most cost-effective.
Apply for funding in a timely manner: Compile all documents for the funding application. The process requires care, but the deadline on 31 August 2025 leaves no room for delays. A specialised partner can provide decisive support here.
Determine vehicle strategy (New vs Conversion): Decide which vehicles will be newly acquired and which will be converted. Especially with expensive special structures, D2E conversion is often the more economical choice and conserves valuable resources. Find out about suitable conversion solutions.
Intelligently plan charging infrastructure: Dimension your charging infrastructure based on the real energy needs of your fleet. Consider charging capacities of up to 165 kW DC for maximum efficiency in operations.
With this plan, you lay the foundation for the financial and technical implementation of your project.
Make optimal use of funding opportunities: Save up to 80% of costs
The current 'Guideline for the Promotion of Alternative Drives for Buses in Passenger Transport' from the BMDV is the central instrument for an economical fleet conversion. It specifically covers the two largest cost blocks.
The funding covers 80% of the additional investment costs for vehicles. This applies both to the purchase of brand-new eBuses and to the professional D2E conversion of existing diesel vehicles. This drastically reduces acquisition costs and accelerates the return on investment. A detailed project outline is required for a successful application, which includes, among other things, the CO₂ savings potential and the degree of electrification. The eBus funding application must be submitted by the deadline on 31 August 2025. The grants are awarded through a competitive process, which is why professional preparation is crucial. In this way, the financial barrier to entering electromobility is significantly lowered.
TCO Analysis: How Conversion Reduces Total Costs
The Total Cost of Ownership (TCO), in other words, the overall operating costs, is the crucial figure for the profitability of your fleet. It includes far more than just the purchase price. Switching to electric drives demonstrably reduces TCO.
The greatest savings occur in these three areas:
Energy costs: The cost per kilometre for electricity is significantly lower than for diesel, often by more than 50%, depending on current energy prices.
Maintenance and service: An electric motor has significantly fewer moving parts than an internal combustion engine. This reduces maintenance effort and the associated costs by up to 60%.
Taxes and levies: Electric vehicles benefit from tax incentives and are exempt from CO₂ levies, further reducing ongoing costs.
Especially with the DTE conversion, the TCO advantage is maximised. You receive a technically as-new electric vehicle with a range of up to 425 km, without having to bear the high investment costs of a completely new vehicle. This not only conserves your budget but also valuable resources in terms of the circular economy. The right charging infrastructure is key to fully realising these advantages.
Charging Infrastructure: The backbone for up to 400 km range
A robust charging infrastructure is the heart of any electric bus network and crucial for operational safety. The planning should be tailored to the specific requirements of your fleet.
Heero vehicles are designed for maximum flexibility. The Tourer minibus achieves up to 400 km range with its 96 kWh net battery and can charge with up to 135 kW DC. The low-floor bus with its 115 kWh net battery even charges with up to 165 kW DC. Charging to 80% often takes only about 30 minutes. The 40% funding from the BMDV for the charging infrastructure makes the investment in powerful DC charging systems particularly attractive. A careful analysis of your idle times and routes, as described in our blog post on e-bus locations, ensures that the charging capacity is optimally sized. This helps avoid expensive load peaks and guarantees maximum vehicle availability, creating the technological basis for a sustainable fleet strategy.
Circular economy in practice: CO₂ reduction through DTE technology
The conversion from diesel to electric drive is a prime example of practical circular economy and sustainability. Instead of scrapping a fully functional vehicle, its lifespan is extended by many years.
This approach reduces the resource consumption for manufacturing a new chassis and body by almost 100%. This alone saves several tonnes of CO₂ per vehicle. In operation, a converted bus then runs completely emission-free and quietly, directly improving the quality of life in cities. With modern battery systems, such as the 115 kWh net batteries in low-floor buses, practical ranges of up to 300 km are achieved. The D2E conversion is therefore not only an economically wise decision but also a strong commitment to ecological responsibility and resource conservation.
