2025
Croatia
HOPS, the Croatian transmission system operator, finished its Climate Risk and Vulnerability Assessment (CR&VA) in September 2025. The study looks at how climate change could affect the Croatian transmission grid under two climate scenarios (RCP 4.5 and RCP 8.5) and across three future time periods up to 2100. The assessment identifies where the grid is most exposed to risks such as storms, flooding, wildfires and extreme heat, guiding HOPS’ plans for future projects.
Highlights
01
Based on EURO-CORDEX climate data and EU Regulation 2021/2139.
02
Created in collaboration with the Ekonerg Institute (Croatia).
03
Includes exposure maps of the grid to climate hazards, risks, and vulnerability of assessts.
Main Information
The CR&VA is HOPS’ first national study on how climate change could affect the power grid. It uses European climate data (EURO-CORDEX) to show which parts of the grid are most at risk from future (extreme) weather conditions. The results are presented in detailed maps that show exposure, vulnerability, and overall risk across Croatia.
The study was carried out with the Ekonerg Institute and follows European rules on climate risk assessment. The findings are planned to shape HOPS’ actions toward strengthening and designing the country’s future grid infrastructure.
