The challenge
Rural mobile care services struggle, beyond the labour shortage, with high fuel costs — average daily distance is around 150 km per vehicle. The goal was a holistic, sustainable energy and mobility concept involving local citizens.
How we delivered it
- 01
Consulting & planning
Calculation of the economically optimal PV and charging-point expansion. The resulting conversion roadmap was the basis for technical delivery.
- 02
Renewable energy
In May 2024 two PV systems totalling 38 kWp were installed on the company premises.
- 03
Charging infrastructure
Eight 11 kW charging points were installed on the company premises.
- 04
Fleet transition
The existing fleet of 15 petrol vehicles is being fully converted to electric step by step.
- 05
Citizen participation
Through profit-sharing rights, employees and patients participate actively in the sustainable transformation of the care service — with attractive interest opportunities for investors.
What the project achieves
- Cost reduction: fuel operating costs fall by 52% per year.
- Attractive return: average internal rate of return (IRR) of 40%.
- Fossil fuel savings: 32,850 litres of petrol per year.
- Climate protection: 77 t CO₂e p.a. from fleet change + 13 t CO₂e p.a. from on-site PV (34 MWh at 380 g/kWh CO₂e).
