Electric bus costs 2025: Optimize TCO with 80% funding and secure deadlines.
Up to 3,500 electric buses already secure 80% funding – when will you electrify your fleet? In light of rising diesel prices and the final funding deadline on August 31, 2025, now is the crucial time to make the switch.
The topic briefly and concisely
The application deadline for the 80% funding for electric buses and 40% for charging infrastructure by the BMDV ends on August 31, 2025.
The Total Cost of Ownership (TCO) of electric buses is often lower than that of diesel buses due to lower energy and maintenance costs.
The conversion from diesel to electric drive (DTE) is a cost-effective and sustainable alternative to new purchases, supporting the principles of a circular economy.
The electrification of your bus fleet is not a question of 'if', but 'when' and 'how'. Bureaucratic hurdles, high initial investments, and uncertainties regarding range hold back many decision-makers. At the same time, the EU regulations of the Clean Vehicles Directive and volatile diesel prices demand action. This guide pragmatically shows you how to reduce current electric bus costs through targeted funding by up to 80%. We explain the crucial steps, from analyzing the Total Cost of Ownership (TCO) to timely application submission, and how retrofitting existing vehicles can strengthen the circular economy.
Transform legal pressure into a competitive advantage
The regulatory framework for fleet operators is tightening. The EU's Clean Vehicles Directive (CVD) already mandates fixed quotas for zero-emission vehicles in public procurement. By the end of 2025, 45% of all newly procured buses must be low-emission, with half of them being completely zero-emission. These requirements apply not only to new purchases but also to service contracts in public transportation (ÖPNV). Many companies underestimate that the deadline for the current funding call from the Federal Ministry of Digital and Transport (BMDV) already ends on August 31, 2025. Those who do not act now risk not only losing up to 80% of subsidies but also facing significant disadvantages in future awards. Therefore, the strategic transition secures you a leading market position. The next step is a clearly defined action plan.
Plan your transition in four pragmatic steps
A structured process is key to success in fleet electrification. With this checklist, you can navigate the transition safely:
Needs analysis and TCO determination: Analyze your current routes and operating costs. Determine the Total Cost of Ownership (TCO), that is the total costs over the lifespan, of an electric bus compared to diesel. In doing so, consider energy, maintenance, insurance, and subsidies.
Make technology decision: Check whether a new purchase or a diesel-to-electric conversion (DTE) is the better solution. A DTE conversion can be up to 50% cheaper for specialty vehicles than a new vehicle.
Apply for funding on time: Compile all documents for the BMDV funding. Note the application deadline of August 31, 2025, to receive 80% of the additional costs for the electric bus and 40% for the charging infrastructure.
Design charging infrastructure: Plan the necessary charging infrastructure at your operating site. Intelligent charging and energy management can reduce operating costs by another 15%.
Securing financing is the most important lever.
Cover up to 80% of the costs with the BMDV guideline
The current funding guideline for electromobility from the BMDV is the central instrument for reducing procurement costs. It subsidizes the additional investment costs of electric vehicles compared to comparable diesel vehicles by 80%. This applies both to the purchase of new E-bus models and to the conversion of existing diesel vehicles. Additionally, the establishment of non-public charging infrastructure is subsidized by 40% of the costs. Applications must be submitted by August 31, 2025, to benefit from these conditions. The funding is designed to significantly lower the economic threshold for switching. It also makes the decision for an E-bus purchase or conversion feasible for small and medium-sized enterprises (SMEs). This financial support fundamentally changes the entire cost calculation.
Use the Total Cost of Ownership as a decision-making basis
The pure acquisition costs of an electric bus are only part of the truth. An analysis of the Total Cost of Ownership (TCO) shows that the higher initial investments are significantly offset by much lower operating costs. A converted e-bus can even be cheaper over its lifetime than a new diesel vehicle.
Energy costs: Electricity is significantly cheaper per kilometer than diesel. Savings of over 50% are realistic here.
Maintenance and repair: Electric drives have fewer wear parts than combustion engines, reducing maintenance costs by up to 60%.
Taxes and fees: Electric vehicles benefit from a ten-year exemption from vehicle tax.
GHG quota: Revenues from trading greenhouse gas reduction quotas create an additional source of income of several thousand euros per vehicle per year.
Especially the diesel-to-electric conversion offers enormous potential for cost reduction. It is a prime example of applied circular economy and conserves valuable resources. This technological solution deserves closer examination.
Maximize efficiency with DTE retrofitting and modern technology
The diesel-to-electric conversion (DTE) is a core competence of HEERO and is often the most economical solution. Instead of scrapping a fully functional vehicle, the diesel powertrain is replaced with a highly efficient electric drive. This not only conserves your budget but also the environment. Our HEERO electric buses rely on cutting-edge technology. The medium-low-floor bus achieves a range of up to 300 kilometers with its 137 kWh battery. Thanks to a DC charging power of up to 165 kW, it is recharged to 80% in around 30 minutes. The tourer for 9 people even achieves up to 400 kilometers with its 110 kWh battery. These values prove that the range anxiety with modern e-buses is unfounded. The performance of the batteries and the charging infrastructure are crucial for smooth operation.
Strategically plan charging infrastructure and battery life
A well-thought-out charging strategy is essential for efficient operation. Depot charging overnight is the most common and cost-effective method. Modern charging and energy management systems optimize charging processes and avoid expensive load peaks. The lifespan of batteries is another important factor. Modern lithium iron phosphate (LFP) batteries are designed for a long lifespan of over 4,000 charging cycles. Even after being used in the vehicle, the batteries still have about 80% of their capacity and can find a second life in stationary storage. This second-life concept significantly improves the ecological balance and TCO of your fleet. This completes the circle from economical acquisition to sustainable operation. Now it’s your turn to set the course.

FAQ
What does Total Cost of Ownership (TCO) mean for an electric bus?
The Total Cost of Ownership (TCO) or overall operating costs include all costs incurred during the entire lifetime of a bus. This includes acquisition, energy costs (electricity vs. diesel), maintenance, insurance, taxes, and the potential resale value or income from the GHG quota. For e-buses, the TCO is often lower because the operating costs offset the higher acquisition costs.
Who benefits from converting a diesel bus to electric drive?
The conversion (Diesel-to-Electric, DTE) is particularly worthwhile for operators with expensive special bodies or relatively young vehicles whose bodywork is still in good condition. It is a sustainable and often more cost-effective alternative to a new purchase, which also conserves resources through the circular economy.
What charging infrastructure do I need for an electric bus?
For the operation of electric buses, a charging infrastructure at the depot (depot charging) is required. The required charging power depends on the fleet size, the cycle plans, and the battery capacity of the vehicles. HEERO offers DC fast charging with up to 165 kW, which allows for short charging times. The construction is subsidized by 40%.
How long does a battery last in an electric bus?
The lifespan of a modern e-bus battery is designed for demanding public transport use and often lasts eight to ten years or more. Even after the end of its use in the vehicle, the batteries still typically have up to 80% of their capacity and can be reused as stationary energy storage (Second Life).
Can I receive the same funding for a conversion as for a new purchase?
Yes, the BMDV's electromobility funding guideline treats the conversion of an existing vehicle as equivalent to the acquisition of a new vehicle. In both cases, 80% of the additional investment costs compared to a reference diesel vehicle are funded.
What happens if I miss the deadline on August 31, 2025?
If you miss the application deadline, you will no longer be able to take advantage of the current very high funding of 80%. Future funding programs are uncertain and may have significantly lower quotas. At the same time, the legal requirements under the Clean Vehicles Directive continue to increase, making it economically difficult to switch without funding.
