Potential and feasibility study for heat supply in Aesch
The municipality of Aesch (BL) is actively tackling the challenges of climate change and is working on a sustainable, economical and secure heat supply for households and businesses. The aim of the municipality is to achieve the national climate targets (net-zero greenhouse gas emissions by 2050) and build an energy-efficient infrastructure.
Due to the revision of the cantonal energy law, natural gas-supplied municipalities such as Aesch will have to draw up a new energy plan over the next five years - a central component of which is heat planning.
Analysis and implementation options
This study analyses how buildings in Aesch can be supplied with emission-free and renewable energy sources for heating and hot water in the future. An analysis of the energy supply from bodies of water and geothermal energy was carried out by eicher+pauli and shows their potential.
Local and district heating solutions also play a special role, as Aesch has a high proportion of non-residential buildings, apartment blocks and terraced single-family houses. TEP Energy has analysed and modelled the economic viability and coverage of these solutions in order to create a basis for decision-making on the future heat supply for the municipality.
The feasibility study takes into account technical, economic and legal framework conditions. TEP Energy uses spatial energy planning methods (read more) to analyse the possible applications of air-water heat pumps, taking into account noise protection and the economic viability of local and district heating networks. At the same time, existing restrictions - such as the groundwater protection area or the limited availability of wood and biogas - are included in the planning.
The project is being carried out in close co-operation with the municipality of Aesch, the Basel-Landschaft Office for Environmental Protection and Energy and eicher+pauli. The results of this study form the basis for heat planning in Aesch.
