上海市火电行业NOx排污费征收标准及情景分析

基于火电行业典型样本的脱硝成本,以调整排污征收标准使得企业得到相对收入,即未脱硝排污费大于脱硝后总支出为判别标准,得出NOx排污征收标准最低值应为1.2元/0.95kg,最终需达到4.0元/0.95kg以上,当征收标准为1.2~10.0元/0.95kg时脱硝总支出占单位电量收入为0.5%~5.0%.根据情景分析,“十二五”征收标准为1.2元/0.95kg时5a总排污费达3.4~4.4亿元,如作为推动企业脱硝建设补贴资金来源,则可补贴额度为23~30元/kW,占实际建设支出的23.1%~30.6%,单位电量总支出占单位电量收入比例为1.5%~1.6%.“十三五”NOx排污征收标准调整为2.4元/0.95kg时5a总排污费为2.9~4.4亿元,可作为NOx超量削减奖励资金,发挥经济杠杆作用,挖掘脱硝设施减排潜力.

Disposing NOx charge standard and charge scenario analysis in Shanghai

Based on the cost of denitration in thermal power to study the charge standard for disposing NOx, the measure standard was that ex-denitration was larger than the total expand by denitration. The outcome was that disposing NOx charge standards imposed the minimum value should be 1.2 RMB/0.95kg, at the end should reach 4.0 RMB/0.95kg or more. The total expand to income unit of electricity was 0.5%~5.0% when the the charge standard was 1.2~10.0 RMB/0.95kg. Therefore, scenario analysis showed that, if the charge standard was raised to 1.2 RMB/0.95kg in the twelfth five year plan, the total sewage charges will be 3.4~4.4 billion. If the sewage charges could be the denitration subsidies, the highest subsidies was 23~30 RMB/0.95kg, and the maximum grant amount of actual expenditures accounted for 23.1%~30.6%. Total expenditure unit of electricity consumption-income ratio was 1.5%~1.6%. The sewage charge was about 2.9~4.4 billion when disposing NOx charge standards imposed adjusted to 2.4 RMB/0.95kg in the thirteen five year plan. The sewage charge could be the incentive funds to the excess NOx reduction, in order to play the role of economic levers, and tap the potential of NOx emission reduction facilities.
