The project aims to introduce innovative and energy-efficient solutions in the power supply system through technical re-equipment of substation No. 23 ZRU-6kV, VRU-35kV, which ensures the functioning of infrastructure facilities in the Ternivskyi district of the city of Kryvyi Rih. Today, the substation equipment is in working condition, but a significant part of it is morally and physically outdated, in particular, oil circuit breakers are used, which have increased operational risks, significant maintenance costs and a lower level of reliability compared to modern technologies. The lack of redundancy at the substation level and the high level of dependence of critical facilities on its stable operation create a systemic risk of emergency shutdowns, which can lead to the shutdown of water supply and drainage, electric transport and energy infrastructure facilities. Thus, there is a significant gap between the current state of the energy infrastructure and the required level of reliability, safety, energy efficiency and compliance with modern technical standards required to ensure the sustainable functioning of the city economy. The project goal is expected to be achieved by:  replacing outdated 6 and 35 kV oil circuit breakers with modern 6 and 35 kV vacuum circuit breakers;  replacing 35 kV disconnectors;  upgrading relay protection and automation systems with the introduction of modern digital solutions;  upgrading current and voltage transformers, insulation equipment;  replacing cable lines of operational circuits;  increasing the level of dispatching and control of energy processes. The implementation of these measures will allow achieving the target level of substation operation that meets modern standards of reliability and safety, reduce technological losses of electricity, increase energy efficiency and ensure stable electricity supply to category I consumers. As a result, the quality and continuity of vital services will be improved, the state of engineering infrastructure will be improved, electricity resources will be distributed more evenly among consumers, and a contribution to climate goals will be achieved through the introduction of more energy-efficient equipment.

The key problem is the use of obsolete equipment, which reduces the reliability of power supply. In particular, the operation of outdated oil circuit breakers, disconnectors, disconnectors, limited capabilities of relay protection and automation systems, as well as wear and tear of auxiliary equipment reduce the overall level of reliability of power supply. The problem is especially relevant given that the substation serves consumers of reliability category I, in particular, water supply and sewage facilities, electric transport and energy infrastructure facilities, the stable operation of which is critically important for ensuring the life of the community. An additional risk factor is the lack of backup power at the substation level, which creates the dependence of a significant part of the city's infrastructure on a single energy node. If these problems are not resolved, there is a high probability of an increase in accidents, which can lead to large-scale power outages. The consequences of such outages may be disruption of the operation of electric transport enterprises and energy infrastructure facilities, as a result, a significant deterioration in the living conditions of the population. The implementation of the project will allow to eliminate the mentioned problems by replacing outdated equipment with modern ones, implementing innovative technical solutions and increasing the level of automation and controllability of the substation. As a result, it will ensure increased reliability of power supply, reduced accident rates, stable operation of critical infrastructure facilities and continuity of basic services to the population. In addition, it is expected to improve the energy efficiency of the substation, reduce operating costs, increase the level of compliance with modern technical standards, as well as strengthen the overall energy sustainability of the community in conditions of increased loads and external challenges. As a result, the implementation of the project will ensure qualitative changes in the functioning of the city's life support systems, increase the level of security and improve the quality of life of residents of the Terni district.
