Two-thirds of the country's electricity is normally generated using water, for example, from run-of-river power plants which use generators that work by channeling the stream through a water turbine.
Austrian summers usually see a lot of rainfall which means that the country can meet most of its electricity demand with water and other renewable sources.
But the drought meant hydropower output has slumped massively - meaning the Alpine country has had to buy expensive electricity from abroad.
Austrians currently pay five times as much for electricity and gas as they did last year. As a result, consumer consumption has fallen significantly.
According to Mr Seidl, there are several reasons why Europe is facing an enormous price rise for electricity.
"The first reason is a lack of generation from thermal power because cooling water is missing. And less generation from hydropower, and a rise in gas prices," he said. Another problem is Austria's lack of grid capacity, which constantly leads to bottlenecks on transmission lines.
