44 | EXAMPLE PROJECTS Germany: “Bioenergy village” Feldheim supplies itself with wind, sun and biogas 55 wind turbines supply most of the village’s electricity, 250 gigawatt hours per year The lion’s share of the electricity, 250 gigawatt hours per year, is supplied by the 55 wind turbines. In addition, there are 2.75 gigawatt hours of solar power, which come from 284 decentralised photovoltaic systems. Together with a lithium-ion battery with a capacity of 10.7 megawatt hours, this becomes an intelligent power grid. A combined heat and power plant with 0.5 megawatts of electrical power generates electricity and heat from biogas. The approximately 130 inhabitants of the village of Feldheim, southwest of Berlin, have taken the topic of energy supply into their own hands: Since 2010, they have been supplying themselves with electricity and heat from renewable energies. 90 per cent of the houses are connected to the local heating network. The customers are also shareholders of Feldheim Energie GmbH & Co KG. They now save 31 per cent on electricity and 10 per cent on heating costs and can rely on stable prices. Local businesses benefit from the construction and operation of the facilities. The project attracts interested parties and is part of collaborative research efforts with universities. In addition, a combined heat and power plant with 0.5 megawatts of electrical output provides 4 gigawatt hours of electricity and 2.2 gigawatt hours of heat for the local heating network per year. It is operated with biogas from maize silage and liquid manure, while the fermentation residues serve as fertiliser. In winter, a woodchip plant provides additional heat. Feldheim has received a grant from the EU for the local heating network. In total, the bioenergy village avoids around 170,000 tonnes of CO 2 emissions per year.
EXAMPLE PROJECTS | 45 Georgia: Small hydropower helps to support tourism The Aragvi II small hydropower plant blends inconspicuously into Georgian nature. In Georgia, hydropower plays an important role in securing a reliable energy supply and reducing dependence on fossil fuels. In the north-east of Georgia, the Aragvi II small hydropower plant supports the electricity supply of the emerging ski and tourism region of Gudauri. For small and large hydropower projects, it is particularly important to assess and consider the environmental impacts before, during and after completion. For the Aragvi II project, it was particularly important that the power plant did not disturb the natural environment. The power plant, which includes the operator’s office, the primary machinery and the turbine, is designed to blend into the mountain landscape. The 2 MW horizontal Francis turbine provided by Voith Hydro generates approximately 13 GWh per year, depending on the season, and was commissioned in early 2019. With many years of experience, Voith Hydro is one of the leading industrial partners for the planning, construction, maintenance and modernisation of hydropower plants in the region. With an output of three megawatts, the turbine generates around 13 gigawatt hours of electricity per year. Hydropower ensures a reliable energy supply and thus promotes tourism in Georgia.
