Project objectives and scope
Zero Emission Mobility: The transport company Sales-Lentz (Luxembourg) has set the goal of completely switching to zero-emission transport by 2030. To do this, it is modernizing its energy infrastructure, replacing 5,000 solar panels installed 20 years ago with more powerful modern models.
Partnership: The project is being implemented jointly with Enerdeal (part of the EDP group since 2023), a specialist in large-scale industrial solar installations.
Technical details
Capacities and technologies: The new panels will increase annual energy production to 1.6 GWh at four sites. Innovative solutions are used, including storage batteries for storing energy during the day and charging the buses at night. The installations will be placed on roofs, on the ground and above carports.
Environmental impact: Annual savings of 700 tons of CO₂ (equivalent to 10 million km of electric vehicle mileage). Old panels will be dismantled and donated to charity.
Financing and payback
Investments: The volume is not disclosed, but we are talking about “tens of millions of euros”.
Government support: 33% of the project cost is covered by Luxembourg subsidies (excluding batteries, which are fully financed by the company).
Cooperation models: Enerdeal either sells projects to clients or finances them independently with subsequent lease (50% of the company’s turnover).
Payback period:
- Without subsidies – 5-7 years.
- With government support – 3-4 years thanks to incentives from Luxembourg, which is actively developing solar energy.
Transport strategy
Electric buses: By 2030, the entire Sales-Lentz fleet (the largest private fleet in the region) should be zero-emission. The company currently has 200 electric buses and plans to increase their number to 600 in 5 years.
Energy autonomy:
The goal is to cover 10% of energy needs from renewable energy sources, despite limitations in the area and capacity of the networks.
Context and market impact
Enerdeal examples:
- Luxembourg’s largest carport with 500 parking spaces for Ceratizit (1.3 GWh/year).
- A 30,000 m² solar installation on the roof for Guardian Glass.
Trends:
Energy efficiency and decarbonization are becoming criteria for business survival. Customers are increasingly demanding “green” solutions in the supply chain. Electricity is a key vector of decarbonization, which is pushing companies to invest in renewable energy.
Conclusion
The Sales-Lentz and Enerdeal project reflects a global shift in the transport and energy industries:
- Technology: Focus on innovation (storage, increasing the efficiency of panels) and synergies between energy and transport.
- Economy: Fast payback of projects due to reduced cost of technology and government support.
- Environment: Ambitious decarbonization goals go beyond the Paris Agreement, demonstrating business leadership in the climate agenda.
This case shows how large companies can combine environmental initiatives with economic benefits, creating precedents for the transformation of the entire industry
