The example of the Yunnan Province demonstrated that rural end-users limited their monthly electricity consumption to a level that makes it completely unattractive to the electricity company to invest further in infrastructure and maintenance. According to the Chinese "one county one supplier" policy, the supplier is to provide the full range of services at a given price. Market access by other investors is difficult if not impossible. This, along with rigid rules on production, supply and marketing of electricity, prevents innovation, competition and reform.
