In the period Summer 2005 until end of the year 2006 a first parabolic trough system has been constructed and operated in Chonburi province, Thailand. The aim was to demonstrate this environmental friendly technology for energy production in Southeast Asia. The regional governments have made decisions to promote solar and biomass energy production by implementing an adder system in 2007. Solar and biomass electricity producers get a fixed additional price per kilowatt hour fed into the national grid. This allows that the private sector invests in renewable energy power plants in the rural areas to meet the demand of electricity. This decentralized energy production ensures the economical development in the rural areas and communities away from the central cities.
