Kölnbrein Arch Dam: A Marvel of Engineering Location: Austria
Completed Cost: $154 Million
Year Completed: 1979
Standing at an impressive height of 660 feet, the Kölnbrein arch dam, located in the stunning Hohe Tauern mountain range, became the tallest dam in Austria upon its completion in 1979. While its striking design captivates the eye, the dam serves crucial functions that extend beyond its aesthetic appeal.
The Kölnbrein dam plays a vital role in the region's energy infrastructure, acting as the primary reservoir for a sophisticated three-stage pump-storage power system. This extensive system includes nine dams and four hydroelectric power plants, all interconnected through a network of penstocks and pipelines. The strategic design allows for efficient energy storage and distribution, harnessing the power of water to generate electricity when demand peaks.
Kölnbrein Dam: Powering Austria's Energy Future The Kölnbrein Dam, a monumental structure owned by Verbund Power Company, boasts an impressive installed capacity of 1,028.5 megawatts (MW). This capacity enables the dam to generate approximately 1,216 gigawatt-hours (GWh) of electricity each year, equivalent to about 4,380 terajoules (TJ) of energy.
This significant power output plays a crucial role in supporting Austria’s energy needs, contributing to a sustainable energy framework that emphasizes renewable resources. The dam's ability to harness water efficiently not only provides reliable electricity but also enhances the stability of the national grid, especially during peak demand periods.
