The invention discloses a monthly commissioning scale analysis method for a new energy project based on a consumption control target, and relates to the technical field of power system analysis, and the method specifically comprises the following steps: giving a province or a region S in the Tth year; inputting a new energy newly-added construction scale W issued by the province or region S at thebeginning of the Tth year; and readjusting the newly-added construction scale W according to the consumption target completion situation, forming the adjusted newly-added new energy installation scale W-adj in the Tth year, wherein W-adj = W-deltaW, the delta W is a preset down-regulation amplitude value, and the delta W can be 100 thousand kilowatts or 500 thousand kilowatts or 1 million kilowatts or the like according to different provinces or region actual situations. According to the monthly commissioning scale analysis method for the new energy project based on the consumption control target, the annual newly-added new energy installation target can be scientifically and reasonably distributed to each month, and a powerful support is provided for formulating the monthly commissioningscale of the provincial power grid new energy project.
