Small Domestic Electrical Installations

Today, microgeneration systems generate relatively small amounts of energy at the site of a domestic or commercial building. However, it is estimated that by 2050, 30 to 40 per cent of the UK s electricity demand could be met by Installing microgeneration equipment to all types of buildings. 

Generator This term refers to generation companies who generate electricity and supply it to networks for transmission and distribution to connected consumers. Since it only relates to generators supplying networks, it can be concluded that the term does not refer to generators that form part of, for example, domestic or small-scale commercial/ industrial installations. 

Numerous examples of small fuel cell-based power units produced and used for domestic applications could be cited. Thus, the Vaillant Group, which has production facilities in a number of European countries, has developed a combined heat and power unit (CHP unit) designed for an electric power output of 4.6 kW and a heat output of 11 kW. Such units were installed in several countries (Germany, the Netherlands, Spain, Portugal). The European Commission has supported 30% of the full project costs, estimated at 8.6 billion [Kommu-nalwirtschaft, No. 2, p. 107 (2004)].
