Large heat storage system (2) Lot 6 Electrical engineering Text automatically translated in your browsing language Automatically translated

27/2024

The client, Stadtwerke Lemgo GmbH (hereinafter also the contracting authority or client), is planning to build an atmospheric heat storage system with a volume of approximately 15,000 m3 at a cylindrical height of 49.5 m at the Liemer Weg site in Lemgo. The jacket of the heat storage system is to be equipped with a PV system (500kW peak, limited to 270kW). Additional plant components are to be erected in a separate building at the site. The following components are planned: an air-water large heat pump (approximately 3.5 MWth), a heat collector system (approximately 2.4 MWth), 2 electric boiler systems (approximately 5 MW), E and MSR technology, pipelines, pumps and fittings and other ancillary equipment. The facilities will be completely rebuilt. The entire volume will be put out to tender in lots (see Part A). In the nearer area of the Liemer Weg there are already regenerative heat generators (solar thermal system, sewage treatment plant heat pump). Depending on the boundary conditions, the heat generation is greater than the heat demand of the network. With the use of the heat accumulator, the excess heat generated is made usable and the yield of the regenerative generators is increased by decoupling heat generation and heat consumption in time. Another task of the storage system is the resting pressure position for the district heating network due to the static height of the water level. In the future, the new large-scale heat storage system will be the central control element for the entire district heating network. This storage facility is then used to control the entire heat supply to the central district heating network Lemgo as required. The height and location are due to operational needs. The commissioning of the entire plant is planned from September 2026, with an award in July 2025. The subject of this procurement procedure (EU procurement procedure (Part 2)) is the construction of an electric boiler system (Lot 4), plant engineering (Lot 5), electrical engineering (Lot 6) and medium-voltage systems (Lot 8).
