Citizen-owned Power Plant Project
Since 2002, Okayama City has been supporting NPO organizations certified by Okayama Prefecture, which install renewable energy power equipments at city-owned facilities with money collected from the public (donation, state subsidies, loans, own funds). The city lends the NPO organizations sites for power station installation at no charge and provides them with the necessary supports for the smooth realization of their projects, based on the consultation with them. The city can use the installed equipments and the power generated by them for the facilities without charge. The surplus electricity is sold to electric power companies. The NPO organizations are in charge of maintenance of the equipments during the statutory life-time. After the end of the period, the organizations transfer them to the city without compensation. The NPO organizations carry out environmental education activities about renewable energy or work on new Citizen-owned Power Plant projects by referring to the results of prior projects. The collaboration of citizens with the municipal administration aims to enhance installation of renewable energy power equipments in Okayama City and to spread information about them among citizens. It is also intended to be a model case of regional development through citizen-government engagement. Project achievements: Three Photovoltaic power equipments have been installed at municipal nursery schools (Fiscal Year 2002: 5.2kw, FY 2007: 10.1kw, FY 20: 10.1kw). For FY 2011, installment of further equipment (5kw) is planned.\" Start year 2002
