RUE action plan

In the context of the Rational Use of Energy (RUE) action plan, Elia’s customers in Flanders (at a voltage level up to and including 70 kV) can submit an application for a grant when implementing measures aimed at saving primary energy.

General Conditions 

What conditions (in Dutch) must a customer meet to claim subsidies to carry out energy-saving measures?

  • First, an energy study needs to be carried out by a recognised energy expert, the customer himself or a third party designated by the customer. Then, the customer submits the application to Elia. Only when Elia has approved the application may the customer order the implementation of the measure.
  • The measure for which a subsidy was requested must have been implemented after a maximum realisation period of 2 years. In the event of unforeseen delays a reprieve may be granted. The request must be made in writing.
  • The maximum total subsidy per customer per site is €200,000 for applications.
  • Invoices must post-date the energy study and may be at most 1 year old on the date on which the invoice is submitted.
  • The subsidies that Elia can grant on the basis of the RUE action plan are limited by the available budget.
  • Measures covered by the CHP and green certificates system (e.g. solar panels) are not eligible for subsidies.



The chart below provides a general overview of the procedure.



Energy study

The energy study or energy audit is carried out by a recognised energy expert, the customer himself or a third party designated by the customer. Energy experts are recognised on the basis of an energy policy agreement, the Energy Planning Decree or some other qualification system adopted by the Flemish government for the provision of energy advice to companies. An energy study or energy audit approved on the basis of some other Flemish government aid scheme is also acceptable.

Here is a list of organizations with energy experts that can perform an energy audit, visit the following web page (in flemish):

To apply for a grant, candidates must use the application form (in Dutch). If Elia deems further information to be necessary to complete the application dossier, it will not hesitate to request it. Among other things, the subsidy application asks candidates to submit for approval a calculation of the measure’s savings potential.

The subsidy is calculated on the basis of the payback time. Priority is given to savings measures that have a payback time (PBT) of two to five years. The subsidy is calculated as follows:

  • PBT < 2 years: no grant;
  • 2 years < PBT ≤ 5 years: grant = (10xPBT-10)%;
  • 5 years < PBT ≤ 10 years: grant = 40%.


The maximum total subsidy per customer per site is €200,000.

N.B.: The payback time for new facilities or extensions to existing facilities is calculated on the basis of the additional investment or additional saving compared with the standard. If the application is declared admissible, Elia will issue an approval decision. The measure in question must only be started once approval has been received from Elia. No subsidy can be granted to projects that have already started before the approval date.


After implementation of the measure, the Measure Reporting Form (in Dutch) must be submitted to Elia. The relevant invoices must also be appended to the reporting dossier so that the whole investment cost is justified by documentary evidence. Elia may also request additional information.
