The purpose of the project "Reconstruction of the 0.4 kV power grid in terms of implementing a ground-based solar power plant for the own needs of sewage treatment plants in the power supply system of the KP "Khmilnykvodokanal" at the address: Vinnytsia region, Khmilnyk, ul. Vugrynovska, 130" is to create a modern, reliable and energy-efficient power supply system for sewage treatment plants by combining traditional sources of electricity with renewable ones. The achievement of the project goal is ensured by implementing the following key methods: Technical modernization of the 0.4 kV power grid Updating outdated network elements, increasing its throughput and reliability of operation. Implementation of a solar power plant Using a renewable energy source to partially cover the own needs of sewage treatment plants. Integration of generation into the existing power supply system Ensuring effective interaction between centralized power supply and own generation. Energy consumption optimization Implementation of energy-efficient solutions and rational equipment operating modes. Automation and monitoring Installation of control, accounting and management systems for electricity consumption and generation. Increasing the level of reliability and safety Implementation of modern protection, backup and safe operation systems. Organizational support for project implementation High-quality design, proper financing, execution of construction and installation works and subsequent maintenance.

Deterioration of electrical networks and equipment Problem: physical and moral aging of cable lines and electrical equipment leads to frequent malfunctions. Solution result: reconstruction of the 0.4 kV network and replacement of equipment will ensure increased reliability, reduced accident rates and stable operation of the system. Dependence on centralized power supply Problem: complete dependence on external sources of electricity creates risks during emergency shutdowns. Solution result: implementation of a solar power plant will allow the facility to partially provide its own electricity and increase energy independence. Risk of interruptions in the operation of treatment facilities Problem: unstable power supply can lead to the shutdown of technological processes. Solution result: a modernized network and the presence of its own generation will ensure the continuity of the facility's operation. High electricity costs Problem: significant electricity consumption creates a significant financial burden. Solution result: the use of solar energy will reduce the amount of electricity consumed from the network and will allow you to reduce costs. Low energy efficiency Problem: lack of modern energy consumption management and control systems. Solution result: implementation of monitoring and optimization systems will allow you to use electricity more efficiently. Lack of use of renewable energy sources Problem: the enterprise does not use alternative energy sources. Solution result: installation of a solar power plant will ensure the transition to partial use of renewable energy and reduce environmental impact. Low energy sustainability of the facility Problem: vulnerability to accidents and instability of the power system. Solution result: creation of a combined power supply system will increase the facility's resilience to external influences.
