This article describes the problem of production localization in the power engineering and electrical engineering industry. At the present time, the Russian economy is facing the issue of competition between domestic and foreign manufacturers in the field of power engineering. This is due, firstly, to the large deterioration of the equipment installed at generation and power transmission facilities, power, and, secondly, to the technologies used for manufacturing the power generation equipment becoming obsolete. The localization of production equipment can partially solve these problems. Furthermore, production localization has to be controlled by the state, for which the so-called localization level is used in world practice. The authors of the article present a study of the existing methods and their comparison. It is also revealed that none of these take into account the specifics of power engineering. As a result of the investigation, the authors propose a method of assessing the level of localization that takes into account the cost of imported raw materials, the price of the final product, the cost of all raw materials used in the production process of power engineering and electrical engineering. In this study, the authors identified a relationship between the localization level and the industry-specific cost and the availability of resources. Therefore, in order to control the localization process we proposed to consider the uniformity of the production localization process. Production localization uniformity entails constructing a system of coordinates along the axes of which lie the localization levels of individual cost items. This localization uniformity is determined by the direction of the line passing through the point of origin and the point of intersection of the levels of localization. The authors defined the conditions that characterize the uniformity of the process of localization and described them in this article. Thus, the authors have developed a tool for measuring and monitoring the production localization process at any stage of the implementation of this strategy.
