Med-TSO has released the 2025 Mediterranean Electricity Interconnection Perspective (MEIP), offering a refreshed look at how stronger electricity links can support a more connected, secure, and sustainable Mediterranean region by 2040.
Developed through the cooperation of experts from the 20 Transmission System Operators member of Med-TSO, the MEIP explores how new cross-border projects can help countries share renewable energy, improve system reliability, and support long-term climate and energy goals.
The MEIP analyses 18 interconnection projects – including 7 exploratory ones – and considers how they could shape the region over the next two decades. By looking ahead to 2040, the report complements the Masterplan of Mediterranean Interconnections 2030, published in November, and it helps to identify what additional infrastructure will be needed as energy systems evolve.
The study shows that developing these projects could bring significant benefits, including:
- 15 GW of additional electricity transfer capacity
- 6,700 km of new transmission lines
- Up to 21 MT/year of CO₂ savings
- Up to 15 TWh/year less renewable energy wasted
- €48 billion in estimated investments across the region
These results highlight how interconnections support a more efficient use of renewable resources, improve security of supply, and contribute to a more resilient Mediterranean Power System.
Med-TSO assesses his studies for the first time ever up to 2040: with its long-term perspective, the MEIP offers decision-makers and stakeholders a clearer overview of the opportunities ahead and the value of working together to build a more connected and sustainable region.
The publication was officially presented on 10 December during an online webinar, which offered further insights into its findings and implications.
