The project's goal is to increase the energy sustainability and reliability of the community's wastewater facilities by building a photovoltaic power plant for a complex of buildings and facilities for biological wastewater treatment. The project is designed to: • provide backup and autonomous power supply for wastewater treatment facilities; • reduce electricity consumption from the network and reduce costs for its purchase; • increase energy efficiency and reduce greenhouse gas emissions; • create a model of sustainable energy supply for critical facilities that can be scaled to other community utilities.

Problems and results of their solution as a result of the project implementation Main problems: 1. High energy dependence of the wastewater treatment system on external power supply, which creates risks of stopping the operation of treatment facilities in the event of accidents or outages. 2. Significant electricity consumption (over 1 million kWh per year) and, accordingly, high costs for its purchase, which increases the financial burden on the KP "Water Supply of Voznesenska". 3. Increasing the cost of electricity and instability of tariffs, which complicate the planning of enterprise costs. 4. Lack of backup power sources, which increases the risks of stopping water supply and the emergence of environmental problems in the event of a power outage. 5. Negative environmental impact due to the use of electricity generated from fossil fuels, which contributes to CO₂ emissions and worsening climate indicators. Results of the project implementation: 1. Increasing energy independence and uninterrupted operation of the wastewater treatment system thanks to its own generation source. 2. Reducing electricity consumption from the network to 40–45% of the current level, which will provide annual savings of up to 80 thousand euros. 3. Protecting the community from power outages - treatment plants will be able to operate autonomously even during outages. 4. Reducing the operating costs of the enterprise and reducing the financial burden on the local budget. 5. Reducing greenhouse gas emissions by 160–240 tons of CO₂ annually, which contributes to achieving the environmental goals of the community. 6. Creating a sustainable energy model that can be replicated at other municipal facilities in the Voznesensk community.
