For the purposes of this network study, the "reference context" as described in Annex 3 "Methodology applied to grid studies" is defined as follows:
The "European generation vector" and the "European load vector" are based on the EU-SAFE scenario of the study "Elia's adequacy & Flexibility study 2024-2034", published in June 2023, for grid situations before 2035 and on the Flex+ scenario of the federal development plan 2024-2034, published in March 2023, for grid situations after 2035.
The "Belgian generation vector" is based on the CENTRAL scenario of the "Adequacy and Flexibility 2024 - 2034" study carried out by Elia in 2023 for grid situations before 2035 and the Flex+ scenario of the federal development plan 2024-2034 published in March 2023 for grid situations after 2035.
The "load vector" is based on load profiles for the reference period 01/03/2022-28/02/2023, forecasts of local consumption trends, sectoral consumption trends, taking into account the limitation of a total Belgian load corresponding to the CENTRAL scenario of the "Adequacy and Flexibility 2024 - 2034" study carried out by Elia in 2023 for the grid situations before 2035 and the Flex+ scenario of the Federal Development Plan 2024-2034 published in March 2023 for grid situations after 2035.
The hourly operational capacity of all generation units and consumers is generated on the basis of a simulation based on flows from the coupling of the European markets, taking into account a minRAM of 70% from the year 2025 and, for the climate years, the historical years 1995, 2007 and 2008 for the grid situations before 2035 and a synthetic climate year for the grid situations after 2035.
