In this article, mathematical models are compiled based on the dynamics of electricity supply volumes in the Republic of Uzbekistan for 2010-2023, as well as for the period from 2010 to 2017 and beyond. The forecast indicators for the period from 2024 to 2030 have been determined. The dynamics of the growth of electricity supply volumes during the study period is also analyzed.

The article clarifies the concept of loss as an object of accounting in order to improve the accounting of expenses associated with the supply of electricity, as well as to identify and assess electrical losses, to fully objectively and systematically reflect them in accounting. It is disclosed that the losses in the economic system of the energy supply organization should be understood as the loss of the asset that exists in the organization, and the cost of sales should be understood as the expenses of the organization. When analyzing losses associated with delivery, the scientific basis for dividing them into more detailed direct losses and inefficient costs is given.
