The overall objective of the research project ‘FLEXibility of the power system in the NETherlands’ (FLEXNET) was to analyse demand and supply of flexibility in the power system of the Netherlands up to 2050 at both the national and regional level. The project was commissioned and funded by the Top Sector Energy (TSE) under the tender programme System Integration. In addition, the project was cofounded by GasTerra and Energie-Nederland. 

FLEXNET was carried out by a consortium consisting of the Energy research Centre of the Netherlands (ECN) and several members of Netbeheer Nederland – i.e. the Dutch branch organisation of energy network operators – in particular Alliander, Enexis, Stedin, TenneT and Gasunie Transport Services (GTS).

The FLEXNET project consisted of three phases, each addressing a specific main question:

  • Phase 1 (‘The demand for flexibility’): what are the flexibility needs of a sustainable and reliable power system in the Netherlands up to 2050?
  • Phase 2 (‘The supply of flexibility’): which mix of robust flexibility options can meet the predicted flexibility needs in a socially optimal way?
  • Phase 3 (‘Societal framework to trade-off grid reinforcement and deployment of flexibility’): in which situations is deployment of flexibility a more attractive option than grid reinforcement to overcome predicted overloads of the power network?

The FLEXNET project has resulted in the following publications (‘deliverables’):
