TransportTo make this measure more effective and tailored to the specific context of your company, we recommend that you first perform an overall analysis of your energy situation.
In most companies, the need for a server room has become a matter of course. Unfortunately, information on the energy consumption of the technological equipment used is not necessarily available prior to installation. IT infrastructures require a lot of energy and represent high costs, which are generally accepted as they are. However, there is great potential for savings.
With a view to optimising the server infrastructure, the following steps indicate a recommended analysis approach.
An in-depth analysis by a company in the sector in question will create a solid basis for any adjustments that may need to be made.
There are a number of possible solutions:
There are other benefits to be considered in relation to outsourcing solutions (e.g. data security, additional services, reduced maintenance costs).
Use the to simulate energy saving measures
In an existing infrastructure, the simulator helps to identify different electricity-saving measures.
Involve the IT supplier or contractual partner in the measures mentioned to reduce electricity consumption.
Attention: incentive effect to be complied with when applying for subsidies (state or otherwise) and subject to compliance with the eligibility conditions.
In order to respect the “incentive effect”, no binding commitment (signing a quotation; paying a deposit) may be made BEFORE submitting the application file or receiving the agreement in principle from the State or the electricity and natural gas supplier following an subsidy application.
Fit 4 Sustainability programme
The Fit 4 Sustainability programme provides co-financing for environmental audits and action plans on one or more topics selected by the company (energy, GHG, waste, water, etc.).
Aid of up to 60%, 70% and 80%, depending on the size of the company, for the fees associated with carrying out an environmental study (energy audit and/or carbon footprint assessment) and a detailed, costed action plan to reduce its consumption/GHG emissions (medium- and long-term investments, ROI, etc.) – open to SMEs and large companies (except those that must carry out studies required by the environmental authorities, including mandatory energy audits)

Aid for environmental protection
The law of 8 December 2025 on the renewal of the aid scheme for environmental and climate protection provides for the granting of investment aid to SMEs and large companies established in Luxembourg, with a business licence, and carrying out projects that contribute to environmental or climate protection.
This aid supports investments aimed at improving energy efficiency outside buildings. It is intended for initiatives that either reduce energy consumption by at least 20% or achieve energy savings of at least 250 MWh per year.
The following maximum rates apply:
| Activity | Company size | ||
|---|---|---|---|
| Small | Medium | Large | |
| Energy efficiency outside buildings | 25 % | 20 % | 15 % |
When equipment is added to an existing installation and there is no counterfactual investment that is less environmentally friendly, the aid rate shown in the table above is doubled.
SMEs may receive aid upon request if they meet the conditions set out in Article 7 of this law, provided that the aid is less than €100,000 and more than €50,000.
Large enterprises, as well as SMEs, will also be able to participate in regular calls for projects, which will be announced below when they become available.
The General Directorate – State Aid and Company Financing will verify the eligibility of applications.
Call for projects for measures promoting energy efficiency outside buildings
A call for projects is open from 5 January 2026 to 30 June 2026 to support measures that promote energy efficiency outside buildings.
This call will be conducted on a ‘first come, first served’ basis, i.e. aid will be granted in the order in which applications are received, until the €15 million budget is exhausted. No specifications have been published; only the conditions specified in the law of 8 December 2025 on the renewal of the environmental and climate protection aid scheme will apply.
SME aid scheme – Aid for miscellaneous investments
10-20 % subsidies to small and medium-sized businesses for miscellaneous investments aimed at promoting the modernisation and competitiveness of the Luxembourg economy.

Any questions?
N.B. State subsidies cannot be combined for the same project.
Since 2015, natural gas and electricity suppliers have been required to make energy savings for consumers under the obligation scheme. Since then, energy suppliers have been offering support and advice, as well as subsidy programmes for consumers to implement energy efficiency measures.
The amount of the premium is proportional to the annual energy saving (in MWh).
The following suppliers offer this service for companies:
N.B. Supplier subsidies can be combined with any state subsidies for the same project.
The tax relief is calculated based on the investments and operating expenses incurred as part of an ecological and energy transition project.
The tax relief rate is set at 18% and is applied directly to the amount of tax due.
This deduction can be combined with standard state subsidies.
For the project to be eligible, it must meet at least one of the following objectives:
For certain objectives, minimum thresholds must be met.
To verify your eligibility and ensure that these thresholds are satisfied, it is recommended that the impact of the measure on one of the above conditions be certified by an expert or a design office.
