The coal-fired power industry in China is confronted with issues on Nitrogen Oxide (NOx) abatement and corresponding additional costs. The selection of denitration technologies and measures is a scientific, economic, and political issue. Several domestic studies estimate the denitration costs and their influencing factors in the context of Chinese power industry. The influencing factors on denitration cost during operations and manufacturing can be credited to the average total cost of denitration. Denitration technologies and measures can be evaluated based on the unit cost of pollution reduction (UCPR), which can be calculated from the marginal abatement cost function. The UCPR was used to examine the cost-effectiveness of each emission reduction technologies and measures. Our analysis shows that the factors, electricity capacity, denitration technology, and construction measure, play incredible roles in determining denitration cost, whereas selective catalytic reduction denitration technology and technological transformation construction measure are the most favored options as regards denitration practice from power plants in China. Given that the mean value of the UCPR is 1.19 cent/kWh, compared with the 1 cent/kWh subsidy, the national denitration subsidy on electricity price is reasonable. Although the NOx abatement strategies provide beneficial effects, some related measures are needed for their implementation.
