Fehlentscheidungen bei Diesel- vs. Elektrobusersatz
Definition
Research on regional WA school buses finds that there is now no economic or technical barrier to a 100% electric school bus fleet, even though current operations use 935 diesel buses on 17-year contracts with about 55 replacements per year.[4] A related project notes that school bus fleets typically run on 15–20 year replacement cycles and that strategies are needed to align those cycles with the transition to battery-electric buses.[6] The Bus Industry Confederation’s fleet replacement modelling shows that differing state ZEB programs (e.g. Queensland, NSW, Victoria) and delays related to ZEB supply can distort replacement timing and average fleet age.[2] In Victoria, the ZEB Transition Plan requires all new public transport bus purchases from July 2025 to be zero-emission and outlines a roadmap for replacing more than 4,500 buses, with some operators switching immediately and others more gradually.[1][3] Without robust modelling tools, operators may continue buying diesel buses where electric is already economically feasible, missing fuel and maintenance savings and potential government support, or switch too early on low-utilisation routes where electric’s higher capex is not recovered.
Key Findings
- Financial Impact: Quantified (logic-based): Studies on electric bus feasibility in regional WA indicate electric school buses can match or beat diesel on total cost of ownership over typical 15–20 year cycles.[4][6] If an operator continues buying diesel instead of switching to cost-competitive electric, they forgo potential savings of AUD 5,000–10,000 per year in fuel and maintenance, yielding AUD 75,000–200,000 over a 15–20 year life per bus. For a 30-bus school/employee fleet this corresponds to AUD 2.25–6.0 million of unrealised savings over one lifecycle if decision-making is not optimised.
- Frequency: High during the current decade (2025–2035) as states roll out ZEB policies and operators face at least one major replacement decision per bus.
- Root Cause: Lack of integrated data on route energy usage, electricity vs diesel prices, infrastructure costs and policy/grant timelines. Decisions are made on upfront vehicle cost rather than full TCO, and risk aversion or misinformation about ZEB feasibility in regional contexts causes delayed adoption.
Why This Matters
The Pitch: Australian school and employee bus fleets waste AUD 50,000–150,000 per bus over its life by mistiming the switch from diesel to electric. Automated scenario modelling of TCO, grants and policy cut-off dates transforms this into savings.
