In 2007, the General Office of the State Council issued "Views on the Implementation of Deepening the Reform on Power System during the Eleventh Five-Year Plan Period" (The General Office of the State Council Doc. No.19 2007), which standardised the restructuring of power enterprises at the county level, and encouraged the involvement of independent power companies. Since 2007, the State encourages all types of investors to invest in rural power grids.
