Croatia recorded a 54.3% fall in variable renewable generation in the week to 20 September, while its net electricity imports increased. The decline was among the sharpest in the region during the same period. Hydropower output rose 34.28%, providing some offset to weaker wind and solar production.
Despite the hydro rebound, Croatia’s net imports rose by 4.20%. Croatian electricity demand fell by 9.76% to 325.54 GWh. The combination of lower demand and higher import volumes indicates a shift in how electricity was supplied during the week.
Supply mix changes and limits of weekly averages
The weekly figures suggest changes in Croatia’s supply mix during a period when consumers used less power. They do not show, on their own, how much of any renewable shortfall was covered by hydropower, domestic thermal generation or imports in each hour. That hourly breakdown is relevant for understanding balancing needs across trading intervals.
Commercially, suppliers must meet delivery commitments when wind and solar output falls. Hydropower operators also face decisions on when to use available generation within the operating day. Import prices and border capacity can influence both supplier coverage and generation scheduling.
Power price movement alongside operational shifts
Croatia’s weekly average power price eased by 0.35%. The limited change coincided with a sharper operational shift, including a steep fall in renewable output and higher cross-border purchases. This occurred even as demand contracted over the same week.
