Harteværket, Hydroelectric power station and technology museum in Kolding Municipality, Denmark
Harteværket is a hydroelectric power station and technology museum in Kolding comprising turbine halls, exhibition spaces, and outdoor areas. The facility displays the technical structure of a working electricity plant while showing how water is converted into power through machinery.
The plant was built between 1918 and 1920 to meet Denmark's growing electricity demand during World War I. It was the country's first major hydroelectric facility and transformed how the region received power.
The plant reflects how Denmark approached industrial development in the early 1900s through innovative energy solutions. Visitors can see how the community depended on this facility to power their daily lives and industries.
Visitors can walk through the grounds and explore different sections, with guided tours available for those who want more details. The outdoor water play area works best in warmer months, and there are picnic spaces throughout the property.
The station still generates electricity for Kolding today using the same water power that made it work over a century ago. This makes it a living working facility rather than simply a museum piece frozen in time.
