The invention provides an economic evaluation method for new energy consumption in consideration of power generation and starting fees. The method comprises the steps of calculating an actual contribution sequence of new energy and thermal power under the condition of loading and a thermal power starting and stopping situation with the maximum consumption of new energy as an optimization objective; calculating coal consumption c1 generated by thermal power generation; calculating starting coal consumption c2 of a thermal power generating unit; calculating a comprehensive coal consumption rate etas; calculating a power generating cost pre of thermal power per kilowatt hour; and calculating the power generating cost which is increased due to consumption of new energy. The technical scheme provided by the invention can objectively evaluate the influence of the consumption of new energy on operating economy, provides a technical base for making a decision of the consumption of new energy, can satisfy the highest consumption of new energy, and also considers the coal consumption rate and the operating cost of the thermal power generating unit.
