Austrian power generator Verbund reported a sharp drop in hydroelectric output in H1 due to poor water supply and lower sales prices, it said on Thursday, with overall generation from all sources dropping 7.9% year over year to 13.32 terawatt-hours from 14.46 TWh.
The hydro coefficient for the run-of-river power plants fell 8 percentage points to 0.68% from 0.76% in H1 2025, 32 percentage points lower than the long-term average.
Hydropower during H1 was 11.19 TWh, 9.8% down from 12.40 TWh a year ago. Wind and solar power were up at 952 gigawatt-hours and 221 GWh, respectively, from 844 GWh and 219 GWh.
There was an increase, however, in power generation coefficient from new renewable plants at 0.82, up 4 percentage points versus H1 2025, but 18 percentage points lower than planned.
