Ukrenergo Taps Icelandic Know-How to Supercharge High-Voltage Grid Efficiency

Partnership aims to boost power-line capacity, speed renewables integration, and accelerate post-war grid recovery. alohavan joi

Key Highlights

  • Strategic Talks: Ukrenergo CEO Oleksii Brech met with Iceland’s Ambassador to Ukraine Fridrik Jónsson to launch a project that upgrades existing 330–750 kV lines with advanced Icelandic technologies.

  • Why Iceland? The Nordic island is a global leader in high-voltage efficiency solutions, thanks to its 100 % renewable electricity mix and long-distance transmission expertise.

  • Project Goals:

    • Increase current-carrying capacity on war-damaged lines

    • Enhance grid flexibility for faster renewable-energy integration

    • Improve reliability of power evacuation from major plants

  • Funding Snapshot:

    • €4 million—Icelandic contribution via UNDP for Ukraine’s energy recovery

    • €5.8 million—additional grant to the Energy Support Fund for Ukraine

    • €0.5 million—direct assistance to Ukrenergo since 2022 Russian invasion


1. What the Upgrade Involves

Component Icelandic Expertise Expected Benefit for Ukraine
High-Temperature Low-Sag (HTLS) Conductors Proven on long Icelandic spans 20–40 % capacity boost without new towers
Dynamic Line Rating (DLR) Sensors Real-time weather-based ampacity calculations Maximises load while preventing overloads
Grid-Hardening Materials Corrosion-resistant fittings for harsh climates Extends asset life amid wartime damage
Digital Twins & AI Analytics Predictive maintenance models Cuts outage risk and repair costs

2. Strategic Impact

  1. War-Time Resilience – Restores lost transmission capacity quickly, avoiding lengthy new-line construction.

  2. Renewables Readiness – Flexible lines ease curtailment and attract new solar-wind investments.

  3. Post-War Reconstruction – Sets technical standards aligned with ENTSO-E, facilitating deeper EU grid synchronisation.

Oleksii Brech, CEO, Ukrenergo:
“Transmitting higher volumes through existing corridors is one of the smartest ways to rebuild faster and greener.”


3. Iceland’s Financial & Technical Support

  • UNDP Channel: €4 million earmarked for transformer repair, spare parts, and grid-monitoring equipment.

  • Energy Support Fund: €5.8 million contribution for emergency gear and grid modernisation.

  • Direct Aid to Ukrenergo: €0.5 million for line-maintenance kits and workforce safety gear.


Next Steps

  1. Feasibility Study (Q3 2025): Joint Icelandic-Ukrainian task force to map priority corridors and tech specs.

  2. Pilot Installation (Q1 2026): Deploy HTLS conductors and DLR sensors on a critical east-west trunk line.

  3. Scale-Out Phase (2026-2028): Expand upgrades across 1,000 km of high-voltage network, funded by EU and multilateral partners.
