Buy electric buses with funding: Your plan for fleet electrification after the 2026 call for applications
Over 3,500 e-buses benefited from government subsidies – when will you electrify your fleet? In view of rising diesel prices and stricter climate regulations, the transition is not a question of "if," but "when." The 2026 funding call for buses ended on July 21, 2026; up to 70% of the additional costs were subsidized.
The topic briefly and concisely
State funding covered up to 70% of the additional costs for purchasing or converting an electric bus and 40% for charging infrastructure; the application deadline ended on July 21, 2026.
Consider the Total Cost of Ownership (TCO) rather than just the purchase price; e-buses save up to 60% on maintenance and energy.
The diesel-to-electric conversion (DTE) is a sustainable alternative to purchasing new vehicles, conserving resources and extending the lifecycle of your fleet.
The electrification of bus fleets is a central challenge for municipalities and public transport companies. High investment costs, bureaucratic effort and technological uncertainties hold many decision-makers back. At the same time, the EU's Clean Vehicles Directive and national climate targets are increasing the pressure to act. This article is your pragmatic guide: We show you how to buy an electric bus or retrofit your existing fleet with a clear 4-point checklist, significantly reduce the Total Cost of Ownership (TCO), and outline where state funding for vehicles and retrofits stands today – the 2026 funding call for buses ended on July 21, 2026. Discover an economically and ecologically sustainable path.
First August 31, 2025: Why now is the right time to act
Converting the fleet remains a strategic decision. The funding guidelines from the Federal Ministry for Digital and Transport (BMDV) most recently granted a subsidy rate of up to 70% of the additional costs for low levels of electrification, otherwise 55%, for the purchase or conversion of electric buses. The 2026 funding call for buses ended on July 21, 2026; a follow-up call has not been announced. This does not take away the urgency of the decision, but shifts its justification to operating costs and regulatory requirements.
In parallel, the European Clean Vehicles Directive (CVD) is increasing the pressure on public contracting authorities. Since August 2021, it has mandated binding minimum quotas for the procurement of zero-emission buses, which will be further tightened from 2026 onwards. Those who postpone the conversion risk not only higher operating costs, but also non-compliance with legal requirements. Following the expiration of federal funding, it is primarily the increasing regulatory requirements that drive the decision for a future-proof investment in an electric bus. The next step is a structured plan for your own fleet.
4-point plan for the e-bus: funding situation in retrospect
A successful transition requires a systematic approach. With the following checklist, you can safely navigate the process of buying an electric bus and properly classifying the funding situation:
Conduct a needs analysis: Analyze your current route profiles with a mileage of up to 500 kilometers per day. Record passenger volume and specific requirements to identify the right vehicle model, from the Minibus-elektro to the 12-meter bus.
Choose the right solution: Decide between a new vehicle and a conversion. A conversion transforms your existing diesel vehicles into high-performance electric buses while preserving your budget and valuable resources – a clear commitment to the circular economy.
Prepare the funding application: Gather all necessary documents; the federal KsNI guideline expired in 2024, and no new funding calls are planned. It funded up to 80% of the additional costs for vehicles and conversions, as well as 40% for charging infrastructure.
Plan implementation and commissioning: Clarify the location requirements for the charging infrastructure with a charging capacity of up to 165 kW. Plan the integration of the new vehicles into operations and the training of at least 10% of your driving personnel.
The choice of the right technology solution is the key to long-term success.
Costs in Focus: Total Cost of Ownership instead of pure acquisition
The higher purchase price of an electric bus initially deters many fleet operators. However, a sole focus on the purchase price falls short. Crucial for an economic evaluation is the Total Cost of Ownership (TCO), i.e. the total operating costs over the entire lifespan of the vehicle. The TCO analysis shows that electric buses often outperform their diesel counterparts after just a few years.
The key factors for the more favorable operating electric bus costs are:
Energy costs: Electricity costs per 100 kilometers are significantly lower than expenses for diesel, often at only 50% of the cost.
Maintenance and repair: Electric buses have fewer wear parts. The elimination of oil changes, exhaust systems, and complex engine components reduces maintenance costs by up to 60%.
Government subsidies: The grant of up to 70% for purchase or conversion lowered the initial investment to the level of a diesel bus and made the TCO attractive; the call for funding ended on July 21, 2026.
Tax advantages: Electric vehicles often benefit from a ten-year vehicle tax exemption.
Particularly, the conversion offers a lever to further optimize the TCO, as the expensive body and chassis are preserved. But it is not only the costs; the technological performance is also convincing today.
Technology that convinces: Mastering range and charging infrastructure
The concern about insufficient range is a thing of the past. Modern electric buses offer practical ranges for almost every purpose. Our HEERO models cover distances of up to 400 kilometers on a single charge, such as the HEERO Tourer for 9 people. Even our specialized low-floor buses reliably achieve up to 300 kilometers. These values are based on real operational data and offer planning security for daily operations.
The battery and charging technology is at the heart of this performance. Here are the facts:
Battery capacity: Our standard models, such as the rear low-floor bus, use a battery with 110 kWh gross and 96 kWh net capacity. The medium low-floor bus has a larger battery with 137 kWh gross (115 kWh net).
DC fast charging: As standard, our buses charge with up to 135 kW. The medium low-floor bus even achieves a charging capacity of up to 165 kW, which reduces the charging time to around 45 minutes for an 80% charge.
Funded infrastructure: The charging infrastructure required for operation was also subsidized at 40% in the 2026 call, which significantly reduced implementation costs.
With the right combination of vehicle and charging concept, the Elektrobusse Reichweite can be optimally managed. This leads to a sustainable solution that goes beyond pure usage.
Sustainability through circular economy: The lifespan of electric buses
An electric bus is more than just a locally emission-free vehicle; it is a building block of the circular economy. This is especially true for the DTE conversion. Instead of scrapping a fully functional bus, its lifecycle is extended by at least ten years. This not only saves around 80 tons of CO₂, which would be generated during the production of a new bus, but also conserves valuable resources.
The battery itself is also designed for long and sustainable use. When a vehicle battery reaches about 80% of its original capacity after many years of intensive use, it is no longer optimal for demanding vehicle operation. However, it is far from being waste. These batteries begin a second life as stationary energy storage systems and help to stabilize power grids or maximize the self-consumption of solar power in depots. Only after this second lifecycle are the batteries sent to a specialized recycling process, where over 90% of valuable raw materials such as lithium, cobalt, and nickel are recovered. This closes the loop and makes the electric bus an all-round sustainable investment.
