The invention provides an evaluation method of an energy-saving type power grid. The evaluation method comprises the steps of 1. establishing an evaluation index system of the energy-saving type power grid, wherein the evaluation index system is provided with four kinds of indexes such as power grid structure, power grid operation, power grid management and power grid equipment; 2. dividing the indexes in the evaluation index system into a maximum type, a minimum type and a moderate type; 3. converting the minimum type index and the moderate type index into the maximum type index; 4. carrying out dimensionless treatment on the indexes; 5. removing the correlation among the indexes; 6. empowering all levels of indexes; and 7. determining a comprehensive evaluation result of the four kinds of indexes according to dimensionless values and weights of the indexes. According to the evaluation method provided by the invention, the energy-saving level can be judged according to the evaluation indexes, thus the advantages and the disadvantages of lower carbon and energy saving benefits of the power grid are obtained; the evaluation indexes are divided into four kinds, namely power grid structure, power grid operation, power grid management and power grid equipment, and the energy saving benefit of the power grid is reflected by each kind on a certain macro level.
