The invention discloses a new district electric power load prediction method for a top design mode. For a newly developed district, due to a lack of historical data, usually prediction can only be carried out by use of a load density method or a load index method, which representing great difficulty in predicting the electric power load of the new district. The technical scheme adopted in the invention comprises the following steps: performing cooperation presetting on the electric power load of an upper-level district where the new district is located to give a predicted value, and dividing a whole region into the new district and an old district according to development situations; using the load intensity method or the load index method to calculate a lower limit and an upper limit of the electric power load of the new district; according to load historical data, predicting the load of the old district; according to a region load prediction value and an old district load prediction value, calculating the new district load; and if multiple districts exist in the whole region, distributing a load to each district according to weight proportions. The method can well overcome the uncertainties in predicting the new district load by use of a conventional method, and improves the credibility of new district load prediction.
