Their core work

MEPSO is the national electricity transmission system operator (TSO) of North Macedonia, responsible for operating and managing the country's high-voltage electricity grid and balancing supply and demand in real time. As a TSO, they coordinate cross-border electricity flows with neighboring grid operators across the Balkans and broader Eastern Europe, which makes them a natural partner in any project touching regional grid integration. In H2020, they contributed operational TSO expertise and real-world grid infrastructure to consortia working on cross-border renewable energy management and intelligent transmission market technologies. Their value to research consortia lies in providing access to an actual national grid system at the southeastern frontier of the European electricity market.

What they specialise in

How they've shifted over time

MEPSO's first H2020 engagement (CROSSBOW, 2017) focused on the physical and technical challenge of managing cross-border flows of variable renewable energy with storage, with ICT as a supporting tool — reflecting the core operational concerns of a grid operator entering the era of high RES penetration. By 2019, their second project (TRINITY) shifted toward the market layer: intelligent market technologies, NEMO coordination, and transmission enhancement through market design rather than just infrastructure. This is a meaningful evolution: from grid physics and storage buffers toward market intelligence and automated trading mechanisms, tracking the broader maturation of European energy market integration.

MEPSO is moving from infrastructure-level grid balancing toward market-layer intelligence, suggesting future collaboration fit with projects on electricity market coupling, automated trading, and smart grid market interfaces.

How they like to work

MEPSO has never led an H2020 project — both participations are as a consortium member, which is typical for national TSOs that bring operational infrastructure rather than research capacity. Despite only two projects, they have engaged with 42 unique partners across 15 countries, indicating large multi-partner consortia where they serve as one of several grid operator validation nodes. This pattern suggests they are easy to bring into large consortia as a real-world testbed, but should not be expected to drive project management or research coordination.

MEPSO has built a network of 42 partners across 15 countries from just two projects — an unusually broad footprint for an organization of this size. Their network is pan-European with a clear emphasis on Eastern and Southeastern European energy actors, reflecting the geographic scope of cross-border TSO projects.

What sets them apart

MEPSO is the only TSO in North Macedonia, which gives them a monopoly position as the entry point for any EU-funded project requiring grid access, operational data, or real-world validation in the Western Balkans energy corridor. For consortia needing a Southeastern European TSO to satisfy geographic diversity requirements or to demonstrate solutions at the edge of the synchronized European grid, MEPSO fills a slot no other Macedonian organization can. Their small funding footprint also suggests they join as lightweight operational partners, keeping consortium overhead low.

Highlights from their portfolio

• CROSSBOW
  Largest of MEPSO's two projects (EUR 181,538) and the broadest in scope — a transnational initiative linking Eastern European TSOs to jointly manage variable renewables and storage across national borders.
• TRINITY
  Marks MEPSO's step into intelligent market technologies and NEMO coordination, showing their engagement with the market-layer of grid management beyond physical transmission.
