Investment aid for energy infrastructure
Do you want to request financial aid for an energy infrastructure investment?
Under the Law of 8 December 2025, the Ministry of the Economy offers investment aid to companies investing in the construction or modernisation of energy infrastructure.
Article 11 supports four categories of infrastructure:
- Electricity networks — transmission and distribution grids
- Gas infrastructure — exclusively dedicated to the use of hydrogen or gas of renewable origin (biogas, biomethane)
- CO2 infrastructure — transport and storage networks for captured CO2
- Heating and cooling networks — district heating and cooling systems
- Projects of common interest — cross-border infrastructure projects listed under EU energy regulation
Please note: No aid may be granted for energy infrastructure that benefits from a full or partial exemption from third-party access obligations or regulated tariffs under EU internal energy market legislation.
Please note: No aid may be granted for investments in gas or electricity storage projects under this article.
Please note: Aid for gas infrastructure may only be granted if the infrastructure is exclusively dedicated to the use of hydrogen or gas of renewable origin.
We can advise you on:
- whether your project and company meet the eligibility criteria
- which infrastructure category applies to your investment
- how to prepare your financing gap analysis and business plan before submitting via MyGuichet.lu
Maximum amount of financial aid
The eligible costs are the total investment costs. The aid may cover up to 100% of the financing gap, defined as the difference between the eligible costs and the operating profit of the investment over its lifetime. The aid is limited to the minimum necessary to carry out the project.
There is no cap on the aid rate under the competitive tendering procedure. Projects are selected on the basis of the amount of aid requested.
Please note: The application must be submitted before the start of works or the first binding order of equipment. Minimum thresholds apply: EUR 50,000 for SMEs and EUR 100,000 for large companies.

Key benefits
Benefit from the following advantages:
-
Total investment costs are eligible
Unlike most other articles under the Environmental Law, Article 11 does not require a counterfactual deduction. The full investment cost is eligible, making this measure particularly suited to large-scale infrastructure projects where no less costly alternative exists. -
No cap on the aid rate
Under the competitive tendering procedure, the aid rate is not capped. The aid is determined by the financing gap and the amount requested, giving applicants full flexibility to request the level of support their project genuinely requires. -
Expert support throughout the process
Luxinnovation helps you assess your eligibility, prepare your financing gap analysis and submit your application via MyGuichet.lu.
