Investment plans

Anticipating future requirements, Elia is already planning future investment projects to develop its grid.

To keep the authorities and the electricity market players abreast of developments, Elia produces investment plans in which it defines the grid development projects it plans to carry out. The investment plans are organised according to the distribution of powers and responsibilities between the different levels of government in Belgium, by voltage level:

At European level, Elia plays an active part in ENTSO-E (European Network of Transmission System Operators). A Ten-Year Network Development Plan covering the entire network of all ENTSO-E members is published every two years.



Federal Development Plan

The Federal Development Plan sets out a detailed estimate of transmission capacity requirements, based on multiple scenarios, and the investment programme that Elia pledges to carry out to meet these requirements.

The Plan factors in adequate reserve capacity requirements and projects of interest designated by the European Union for trans-European networks. Since 2006, the Plan has also been accompanied by an environmental impact report.

It is drawn up in collaboration with the Directorate-General for Energy and the Federal Planning Bureau, in accordance with the Electricity Act of 29 April 1999 on the organisation of the electricity market.
