FLUVIUS SYSTEM OPERATOR

Their core work

Fluvius (formerly Eandis) is the distribution system operator (DSO) for electricity and gas across the Flanders region of Belgium, managing the grid infrastructure that connects energy producers to millions of end users. In H2020, they contributed real-world grid operations expertise to projects addressing TSO-DSO coordination, household energy efficiency, and sustainable public buildings. Their role centers on demonstrating how distribution networks can integrate renewables, enable demand response, and support municipal climate targets at scale.

What they specialise in

How they've shifted over time

Fluvius entered H2020 in 2017 with a focus on consumer-facing energy saving (ASSIST), then shifted toward grid-level coordination and long-term sustainability planning in 2019 with CoordiNet and SURE2050. The later projects reflect a move from end-user support toward systemic challenges: market design for grid services, renewable integration, and municipal decarbonization strategies. This mirrors the broader European shift from energy efficiency awareness toward active grid transformation.

Fluvius is moving toward active grid management and market-based coordination of distributed energy resources — a direction that will intensify as renewables penetration grows in Flanders.

How they like to work

Fluvius participates as a partner or third party, never as coordinator — consistent with its role as an infrastructure operator contributing real-world testbeds rather than leading research. With 51 partners across 12 countries from just 3 projects, they join large consortia where their value is providing operational grid data and demonstration sites. They are a reliable infrastructure partner rather than a research driver.

Through 3 projects, Fluvius has connected with 51 unique partners across 12 European countries, reflecting participation in large-scale demonstration and coordination actions. Their network spans Southern, Western, and Northern Europe typical of energy grid projects.

What sets them apart

Fluvius is the sole DSO for all of Flanders, giving it unmatched access to regional grid data, municipal partnerships, and millions of connected households. For any consortium needing a real-world distribution grid testbed in Belgium, Fluvius is effectively the only option. Their dual focus on grid-level operations and municipal climate commitments makes them a bridge between technical energy projects and local governance.

Highlights from their portfolio

• CoordiNet
  Large-scale demonstration of TSO-DSO coordination for grid services procurement — directly relevant to the future European electricity market design.
• SURE2050
  Combines energy efficiency with public real estate strategy in Flemish municipalities, linking Covenant of Mayors 2030 commitments to concrete financing and management plans.
