Saane water to heat Freiburg
Groupe E wants to utilise the water of the Saane to generate renewable heat for the greater Fribourg area. The PLACAD project provides for the expansion of an existing heating centre, a pumping station and two 1.2-kilometre-long parallel pipelines.
By 2027 at the latest, water from the Saane will cover 10 per cent of the heat demand in the Fribourg area, Groupe E announced in a press release. The energy supplier from Granges-Paccot is planning to build a three-part infrastructure to generate around 60 gigawatt hours of renewable thermal energy per year. This is enough to cover the needs of around 7500 households.
The PLACAD project provides for the expansion of the existing heating centre on the former Ritter site. In future, three water-to-water heat pumps will operate here. They will be supported by two gas boilers in winter or in an emergency.
The associated pumping station is planned in the Magere Au dam building. The connection between the heating centre and the pumping station is via two parallel pipes, each 1.2 kilometres long. They run through the Perolles forest, under the tennis courts of the Heilig Kreuz college and across the Saane.
The pipeline route will partly follow existing paths, but any environmental impact will be compensated for, Groupe E explains. This includes plans to extend the Lake Perolles nature reserve to include an island of old woodland. Groupe E will provide information online about any adverse effects on leisure activities in the Perolles forest. The corresponding website also provides an insight into the development of the project.
