The Salzburg Mitte thermal power station is a district heating power station and a power station for generating electricity. The cogeneration plant is on the edge of Salzburg's old town in the Elisabeth-Vorstadt district , directly on the Salzach . The Salzburg Mitte substation is connected to the area . They are operated by Salzburg AG .
The power plant is characterized by an exceptional architecture because it is located in the buffer zone of the UNESCO World Heritage Historic Center of the City of Salzburg . The substation is also considered to be architecturally outstanding. They were planned by the Swiss architecture firm Bétrix & Consolascio (Marie-Claude Bétrix, Eraldo Consolascio) with Eric Maier , who also designed the Nord heating power station .
History and architecture
Old central heating plant
The central heating plant was built in 1955 by the then Stadtwerke Salzburg (today Salzburg AG) directly on Elisabethkai near the Lehener Bridge , bordering the Westbahn out of town , to provide a customer-oriented district heating source for the developing districts of Elisabeth-Vorstadt , Lehen and Schallmoos . After ten months of construction, it was put into operation on October 10, 1955.
Flue gas cleaning system and substation in Salzburg Mitte
In 1987, a flue gas cleaning system was retrofitted in order to reduce sulfur dioxide emissions in the middle of the city. It was designed by Bétrix & Consolascio as a circular disc segment structure, the Kapuzinerberg (eastern) facade has decorative structures reminiscent of fortifications, which already point to postmodernism . The roof has a brick structure, the sides fine horizontal chiselling. The cleaning system forms the middle of the system ensemble.
In 1989 a new substation was planned and carried out in 1992–1995. The building, at the corner of Alois-Schmiedbaur-Straße / Gebirgsjägerplatz (northeast corner of the area), is an intersection of two cubic structures that denote work and operating rooms. The structure is designed to be transparent to the material: The operating wing is made of light-colored concrete, facing the Gebirgsjägerplatz with a row of windows and an arcade-like space to the street, with a fully glazed sales area (today the office of the Chamber of Architects and Engineering Consultants). The second body is made of wooden formwork and lies along the mountain hunter's place over the operating wing. It contains loading zones, technical rooms, offices, two roof gardens and a small official apartment.
Another operational building is integrated in the L-shaped substation.
Central heating power plant with new operating building
In 1999–2003 the outdated power plant, directly on Elisabethkai, was rebuilt. Since it is located directly in the buffer zone of the UNESCO heritage (the old power station had a red-and-white-striped chimney as usual and otherwise purely functional concrete complexes), a structurally appropriate solution had to be found. Especially the classic view from Mönchsberg over the old town towards Maria Plain has the Elisabeth suburb and the power plant in the background.
Bétrix, Consolascio and Maier developed a very formalistic solution (draft 1995). The monolithic, altogether 120 meter long building of the power plant presents itself as concrete, anthracite colored , stepped cubic body, likewise the 70 meter high chimney. The design is in the tradition of brutalism ( French brut 'raw'). Experiences from the neutral retouching of the restoration practice flowed into this , that color-neutral surfaces are set back, so that the building can disappear in the shadow of the urban landscape despite its massiveness. The pumping station is located on the Salzach, as a cube in the same surface, but white, as an opposite pole and accent, which reveals its technical function even less.
Next to it, in the south-east corner towards the underpass of Schwarzstrasse, a company building was built, a simple, staggered storey in exposed concrete, opened on the bottom floor by a ribbon of windows (design 2000). The interior of the company building is intimate and friendly in contrast to the exterior.
The design was approved by the City of Salzburg's Design Advisory Board, which is responsible for major projects. In architectural circles it is considered a prime example of modern industrial architecture in dealing with the requirements of cityscape protection . However, the “bunker-like” design caused a stir among the population, the appearance of the power plant is still controversial today. Recognition with the architecture prize of the State of Salzburg - the company building was nominated, not the power plant itself - failed due to political influence.
The district heating plant has been illuminated in blue at night since 2009, an installation by the Salzburg lighting designer Herward Dunkel.
Technical equipment and operation
The power plant is equipped with a heavy oil- fired gas and steam system. It has a thermal output of 127 MW and an electrical output of 85 MW ; the annual production is 322.485 million kWh of heat and 314.43 million kWh of electricity. The heavy oil boiler (built in 2001) has a fuel heat output of 90,000 kW, the gas turbine with waste heat boiler (2003) of 165,600 kW. The bottleneck power is 54,700 kW electrical (gas turbine), 28,960 kW electrical (steam turbine), 127,000 kW (thermal).
The combined heat and power plant supplies 34,000 households with electricity and 27,000 more with heat, especially the Salzburg state hospitals .
Around 3000 cubic meters of water from the Salzach are withdrawn every hour for cooling and, for nature conservation reasons, fed back at a maximum of 10 degrees more than when it was withdrawn.
Since the integration of the waste heat rail south (AWS) and the biomass cogeneration plant in Siezenheim , the power plant can temporarily be completely shut down in summer, and the city is supplied with renewable energy and waste heat.
