The traditional environmental impact assessment (EIA) hadn’t convert the environmental benefits of power generation by using natural gas into currency
resulting in gratuitous occupation of their environmental value (EV). By using the theory of environmental economics
an assessment of the EV for power generation by using natural gas has been carried out. The results show that the EV of power generation with natural gas can reach to RMB89.639 yuan/(MW·h)
providing basis for reference to the EV trading in the power market.
