Bioenergy villages have been implemented in Germany and Austria very successfully. This experience can be used for the initiation and preparation of more bioenergy villages in other European countries. The main challenge of the development of bioenergy villages is the social component. Structures have to be established that allow a broad citizen participation process and the integration of all relevant stake�?¬holders and decision makers. When Energy Conservation Measures (ECMs) bundles are modelled, the results have to be revised with regard to the synergetic effects between ECMs and energy supply measures. High energy savings from measures in the buildings de�?¬crease the energy demand and reduce the viability of e.g. a district heating system. Different types of biomass sources and renewable energies can be applied in different pathways in bioenergy villages. The assessment of the technical solutions typically follows technical, economic and environmental metrics. Three main operating models are applied that vary in accordance with the regional circumstances: The citizen model, the ESCO model and a combination of both models. The selection of the legal entity for the citizens model depends on criteria such as the structure of organisation, the liability and other risk factors, the minimum capital and the decision-making process. The shared ownership model can also be applied, then public or private building owners finance a share of the measures, e.g. the ECM in their buildings. Regarding the economic assessment of the project, a life cycle analysis is recommended that covers full costs over the life-cycle and discounts these costs according to the year when they occur. Since bioenergy villages comprise extensive bundles of technical measures, the financing of these investments is a crucial point of the concepts. Besides the planning of the biomass supply and the technical and economic calculation, also the financing concept, the potential operating and the ownership models, the legal structure and the risk assessment should already be elaborated within the preparatory.
Konstanze Stein is a Project Manager at KEA Climate Protection and Energy Agency Baden-Württemberg. She has been working for KEA since 2004, first at section grant programs and since 2005 at energy service development section. She has steered a lot of energy service projects in Baden-Württemberg and has advised municipalities regarding energy efficiency. Currently, she works in the European BIOVILL project that focus on transfer of experience gained in countries where bioenergy villages already exists (Germany and Austria) to countries with less examples in this sector. The evaluation of existing bioenergy villages and the compilation of the different components of these business models are crucial elements of the project.
