Abstract: Pricing mechanism of heating supply by wind power and its economic factors were analyzed by a case study. The results show that, based on the current unit-heating price, heating demand and heat station investment, treating heat station and wind farm as a whole has better economics than treating the heat station alone. Moreover, with a given condition of unit-heating price, heaing demand and heat station investment, the maximum electricity price that can be afford by a heat station should be controlled in a certain range to make the project profitable. Subsidizing for the investment of a heat station could be used to ensure the profit of the projects of heating supply by wind power.
