FINGRID OYJ

Their core work

Fingrid is Finland's national electricity transmission system operator (TSO), responsible for operating and maintaining the high-voltage power grid that connects power producers to regional distribution networks and to neighboring countries. In H2020 projects, they contribute real-world grid operational expertise, helping develop solutions for integrating massive volumes of renewable energy, managing cross-border power flows, and designing new market platforms where transmission and distribution operators coordinate with consumers. Their participation brings the perspective of a large-scale grid operator managing one of the most interconnected Nordic power systems.

What they specialise in

How they've shifted over time

Fingrid's H2020 journey began with fundamental grid stability challenges — MIGRATE (2016) tackled the physical effects of integrating large volumes of power electronics into the transmission network. From 2019 onward, their focus shifted decisively toward market architecture and operator coordination: INTERRFACE addressed TSO-DSO interfaces and pan-European market design, while OneNet pushed toward a unified European energy network. The trajectory is clear — from hardware-level grid challenges to software-level market platforms and multi-actor coordination.

Fingrid is moving toward pan-European energy market harmonization and digitalized grid coordination, making them a strong partner for projects designing the operational architecture of Europe's future unified energy system.

How they like to work

Fingrid participates exclusively as a consortium partner, never as coordinator — consistent with their role as a national infrastructure operator contributing domain expertise rather than managing research projects. They work in large consortia (131 unique partners across 3 projects), which reflects the nature of pan-European grid harmonization efforts that require participation from TSOs, DSOs, and market actors across many countries. This makes them a reliable, low-maintenance consortium partner who brings real operational data and grid-level validation capabilities.

Fingrid has collaborated with 131 unique partners across 27 countries in just 3 projects, reflecting their participation in some of the largest European energy system coordination initiatives. Their network spans virtually all EU member states, with strong connections to other Nordic and Central European TSOs.

What sets them apart

Fingrid operates one of Europe's most advanced and interconnected transmission grids, with strong cross-border links to Sweden, Norway, Estonia, and Russia. As a national TSO, they offer something most research partners cannot: access to real grid operational data, validation environments at transmission scale, and direct influence on how European network codes are implemented nationally. For any consortium working on energy system integration, grid services, or market design, Fingrid brings the operator's seat at the table.

Highlights from their portfolio

• OneNet
  Largest funding (EUR 484,575) and most ambitious scope — designing a single pan-European network for coordinating TSOs, DSOs, and consumers across all energy markets.
• INTERRFACE
  Directly addresses the TSO-DSO-Consumer interface architecture, a critical bottleneck for deploying grid services across Europe's fragmented energy system.
• MIGRATE
  Tackled the foundational challenge of massive power electronics integration into the European grid — a precondition for renewable energy scaling.
