Ever been powered by beer? Here, at the Wasserkraftwerk Pulvermühle, it is more than a catchy slogan. It is a liquid legacy.
The Wasserkraftwerk Pulvermühle stands as a testament to Salzburg’s innovative spirit. It also shows how the city harnesses its natural resources. This historic watermill, now a power plant, has been a vital part of Salzburg’s energy landscape for centuries.
The story of the Wasserkraftwerk Pulvermühle is intertwined with the Almkanal. The Almkanal is an artificial waterway that has supplied Salzburg with water since the Middle Ages. Its origins trace back to the 8th century. The oldest section is the Müllner Arm. This channel regulated and diverted the Riedenburgbach. Mills were built along this channel. They gave the suburb of Mülln its name.
In the 12th century, the Domkapitel and Stift St. Peter ordered a tunnel to be built through the Mönchsberg. This Stiftsarmstollen was constructed from 1136 to 1143. To supply enough water to the mills at the tunnel exit, a wooden channel was built. It ran through the Leopoldskroner Moor to the Rosittenbach. Excess water flowed to the Riedenburgbach. This led to the mills in Mülln. At this water division point, the Pulvermühle emerged. Today, it is the Stieglbrauerei power plant in Leopoldskron.
By the late 19th century, the Almkanal powered up to 120 mill wheels. Over 400 water rights existed.
Since 1906, the Stiegl brewery operates this power plant. The Wasserkraftwerk Pulvermühle contributes to covering peak demand. It also provides emergency power to the brewery.
Today, the Almkanal still powers 18 power plants. These produce a total output of 1.2 MW. The Eichetwerk is the oldest hydroelectric power plant in Salzburg. The Wasserkraftwerk Pulvermühle and the municipal emergency power generator are also powered by the Almkanal. Thanks to sufficient water supply even in winter, the annual power generation is 8.5 GWh. This corresponds to the electricity needs of approximately 2,400 households.
The Wasserkraftwerk Pulvermühle is not just a historical landmark. It continues to play a crucial role in Salzburg’s sustainable energy efforts. This power plant combines tradition with modern technology. It offers a glimpse into the city’s past and a vision for a greener future.
As you stand here, consider the ingenuity that has kept this Wasserkraftwerk Pulvermühle running. Also, think about the power of water and its enduring impact on Salzburg.
