AHP is by far the largest producer of environ- mentally friendly electricity from hydropower in Austria. AHP uses its power plants to ensure that Verbund and its customers always have access to the eco-product “Austrian Hydro Power”. “Austrian Hydro Power” is a clean energy generated from 100 % hydropower and bears the TUeV quality seal.

Such projects resulted in the erec- tion of the »Reisseck/Kreuzeck power plants« and the »Malta power plants«.

The Malta storage power plants have an output of 891,000 kW with an additional 406,000 kW from the storage pumps in the Galgenbichl and Rottau power stations and use natural inflows to generate more than 900 million kWh of valuable electricity each year from environmentally friendly hydropower.
