Største kraftverk i Tyskland

The Großkraftwerk Mannheim (GKM) is Germany's largest power plant, located in the Rhine-Neckar metropolitan region. The GKM produces electricity for over 2.5 million people, businesses, and industries, and provides district heating for around 120,000 households. With the commissioning of Block 9 in May 2015, GKM became the largest energy site in Baden-Württemberg.

Block 9: Effektivt og miljøvennlig

Block 9 was constructed as a replacement for Blocks 3 and 4 and became operational after a six-year construction period, starting from May 2010 and concluding in May 2015. With a capacity of 911 MW, Block 9 sets new standards in environmental and climate protection, thanks to its efficiency rate of 46.4% and fuel utilization of up to 70%. The façade project for Block 9, carried out by Implenia Fassadentechnik, involved the implementation of a double-skin, thermally and acoustically insulated cladding, and flat roof structures, costing around 12.5 million CHF (approximately 10.258 million EUR).

Omfattende byggearbeid inkludert

The contract for the new power plant block was awarded to a consortium under the technical leadership of Implenia's predecessor. The scope of work included the extensive construction of both main and auxiliary facilities, consisting of more than 26 individual structures, such as the boiler house, machine hall, stair towers, and fly ash silos, mostly built using slipform construction. Critical infrastructure such as the switchgear building and coal storage were also part of the project, with the primary constructions predominantly deep-founded.

Betydelige infrastrukturarbeid fullført

Besides the core structures, the project included substantial infrastructure works within the facility, such as the construction of roads, rail systems, and underground utilities. Key materials moved and used during construction consisted of 430,000 m³ of earth excavation, 130,000 m³ of reinforced concrete (15,000 m³ built using slipform), and 39,400 m² of steel sheet piles. The total value of the executed works amounted to 222 million CHF. The construction faced significant challenges due to the large volume of materials that needed to be handled within a confined site area.

Moderne hardkullkraftverk ferdigstilt

Block 9 of the Mannheim coal power plant was officially put into operation in September 2015 and is considered one of the most modern hard coal power plants globally. Implenia's role included the construction of several critical structures, such as the cooling water induction structure, machine hall, steam generator building, switchgear building, cooling water pump structure, and transformer building. The project also encompassed the build-out of flue gas desulfurization and cooling water intake structures.

Avansert forskalingsinnsats levert

Implenia employed various formwork systems, including Trio, support brackets SB 1 and SB 2, flexible formwork for ceilings, heavy-duty shoring systems like Peri Up, and KG 240 consoles for climbing units. One major challenge of the project was the planning and erection of thick components, particularly turbine tables, on heavy-duty shoring systems. The formwork and formwork construction in the power plant were the main application areas for Implenia in this 1.6 million CHF project, executed under the consortium of Bilfinger, Diringer & Scheidel, Ed. Züblin, and Heberger.
