TERNA - RETE ELETTRICA NAZIONALE SPA

Their core work

Terna is Italy's national electricity transmission system operator (TSO), responsible for planning, managing, and operating the Italian high-voltage grid. In EU research, they bring real-world transmission network expertise into collaborative projects — validating methodologies, providing operational data, and ensuring that academic solutions are grounded in actual grid constraints. Their H2020 participation focuses on integrating flexibility resources (storage, demand response, renewables) into transmission and distribution planning, and on defining market mechanisms that enable the energy transition at system scale. They are not a research lab: they are the grid owner asking "does this actually work for a national TSO?"

What they specialise in

How they've shifted over time

In their earlier H2020 engagement (OSMOSE, starting 2018), Terna's focus was on the macro level: how should Europe's electricity system combine flexibility sources, and what market rules are needed to support the energy transition? By 2019, with FlexPlan, the focus shifted toward concrete planning tools — specifically how to incorporate storage and flexible resources into T&D grid expansion decisions using regional scenarios. The direction is clear: from system-level market design toward operational grid planning methodologies that a TSO can actually embed in investment decisions.

Terna is moving from contributing to high-level flexibility frameworks toward applying planning tools operationally, suggesting future collaborations that produce TSO-ready decision-support methodologies will be the strongest fit.

How they like to work

Terna participates exclusively as a consortium partner — never as coordinator in these projects — which reflects their industry role: they join to validate and apply research, not to lead academic work packages. Their 58 unique partners across just 2 projects indicates very large international consortia, typical of energy system projects under Horizon 2020 where multiple TSOs, universities, and technology providers collaborate. This means working with Terna requires fitting into a crowded consortium, but gains you access to real Italian transmission grid expertise and data.

Terna has built connections with 58 distinct organisations across 10 countries through just two projects, which reflects the scale of pan-European energy consortia rather than a dense personal network. Their reach is clearly European, spanning multiple TSOs, research institutes, and technology companies across the continent.

What sets them apart

Terna is one of Europe's largest TSOs, operating roughly 74,000 km of high-voltage lines — this gives them something almost no research partner can offer: real grid data, operational constraints, and the institutional authority to say whether a methodology is deployable. For any project targeting European grid flexibility or transmission planning, having Italy's TSO in the consortium provides immediate credibility with regulators and other national operators. Their participation signals a project is serious about implementation, not just academic publication.

Highlights from their portfolio

• OSMOSE
  The largest of Terna's two funded projects (EUR 745,707), it tackled the full stack of flexibility — from technical options to market design — at a European system scale, positioning Terna at the centre of energy transition policy debate.
• FlexPlan
  Represents a pivot toward concrete TSO planning tools, using regional scenario modelling to evaluate how storage and flexibility should reshape grid investment decisions across transmission and distribution networks.
