TY - JOUR N2 - The paper presents the main issues of the management of electrical grids. Selected information technology tools supporting electrical grids maintenance are presented. In electrical infrastructure maintenance of power companies, geographic information systems are increasingly used to support the management of their resources. Their functionalities in terms of creating comprehensive databases for the electrical infrastructure of the power sector are described. The important information technology tools regarding spatial systems for supporting maintenance and operation management electrical grids and the conditions of their implementation are presented. This paper also attempts to present an innovative multidimensional evaluation of the technical and economic benefits resulting from the use of modern information technology tools for the management of energy infrastructure.
