The virtual tour and the presentation of the solar thermal energy supply of “Energie und Wasser Potsdam” was a highlight of the AGFW event "Solnet 4.0 - Online Workshop Solar Heat Networks - Market Status Today and Approaches for Sustainable Development Tomorrow (Solare Wärmenetze – Marktstand heute und Ansätze für eine nachhaltige Entwicklung morgen)" on 23.09.2020.
In this video Mr. René Elgert (construction manager of the solar thermal power plant from Energie und Wasser Potsdam GmbH) gives detailed insights into the technical concept, the implementation and then operation of the collector field, the integration into the district heating network and the technical center (heat station).
In the joint research project, funded by the Federal Ministry for Economic Affairs and Energy (BMWi), AGFW, Solites, the Hamburg Institute and the publishers of the trade journal “Energiekommune” had set themselves the goal of providing practical information about the technology and user concepts of solar thermal energy, visiting systems and clarifying open questions.

Solar thermal energy in district heating
Heating networks with renewable energies offer promising opportunities to make progress in the local heat transition. Increasingly, large-scale ground-mounted solar thermal systems are being integrated in this process. Today, these systems are implemented by heating suppliers primarily for business reasons and as a measure of local climate protection. The current double-digit growth is mainly taking place in two areas: existing urban district heating networks in metropolitan areas and smaller, mostly new heating networks in rural areas. There are also promising market prospects for the housing industry.

Located in the northwest part of Germany’s capital city Berlin, Vattenfall operates the combined heat and power plant Reuter West. Commissioning in 1987 and 1989 the two identical heat and power plant units generate electricity (installed capacity of 564 MWel) and heat (installed capacity of 878 MWth) simultaneously according to the principle of cogeneration. Despite the age of the CHP of 30-years, the fuel utilization efficiency amounts to 80% due to ongoing efficiency and optimisation measures.
Equipped with efficient flue gas cleaning systems the generation units still represent a highly efficient hard coal plant. To reach the climate goals and supporting the heat transition Germany decided to have a coal phase out during the next years. As a result, the heat and power generation needs to find some alternatives and Vattenfall Berlin has already been driving this process for several years.
In September 2019 for example, Vattenfall connected Europe‘s largest power-to-heat plant (120 MWth) to the district heating network at the Reuter West power plant area in Berlin. As the general optimisation and upgrade process and the transformation to higher shares of renewable energies are also targets of European (H2020) research activities the virtual study tour is embedded in an online webinar from Upgrade DH and RES-DHC.
Sign up to participate at the high-level webinar with examples and ideas from all over Europe and join the virtual study tour. In addition to visiting some areas that are not accessible otherwise and insights of ongoing innovative activities for the real heat transition, you will afterwards have the opportunity to find your own way through a virtual model of Reuter West.
