The main task in the design of power supply is the development of the project and its feasibility study (feasibility study), as well as engineering solutions that will ensure reliable operation of the future system and high-quality, uninterrupted supply of consumers with electricity at the lowest cost.
The basis for the design of power grids is the elaboration of materials that substantiate the necessity and expediency of both the development and re-equipment of existing grids and the arrangement of completely new power supply areas. This includes: the permanent power supply scheme, sections with the development of power grids as components of power plants and schemes of external power supply of large industrial facilities. This document needs to be approved in order to start the power grid design procedure itself.
