Project goal: The project is aimed at creating a reliable, autonomous and energy-efficient energy supply system for the critical infrastructure of the community by installing cogeneration units (CGU) with a capacity of 2 MW at one of the city boiler houses and gradually connecting them to its key municipal facilities. The implementation of the project will allow the formation of a local energy cluster ("energy island"), which will ensure stable heat and electricity supply during peak loads or emergency situations in external networks. The main tasks of the system project include the installation and integration of a cogeneration unit into the heat supply of the boiler house; use of the generated heat for heating a residential area adjacent to the boiler house, which will increase overall efficiency and reduce the cost of heat energy production; directing the generated electricity to power critical infrastructure facilities of the community (boiler houses, water utility, city hospital), and later - other budget institutions; construction and modernization of its own electrical networks to ensure flexible and safe energy distribution; creation of technical conditions for expanding the energy "island" and connecting new consumers in the future. The project is being implemented in stages, taking into account the technical and financial system of works. A number of prepared steps are already in place, which form the basis for further implementation: a feasibility study (FEO) has been developed in cooperation with the Association of Housing and Utilities Energy Auditors, which confirmed the feasibility of installing a CHP and determined the basic parameters of the project; a preliminary connection scheme and the formation of an energy island have been developed, which allows localizing critical facilities and providing them with backup power in the event of a disconnection from external networks; an audit of energy consumption by the main community institutions (boiler houses, hospital, water utility) has been conducted, which made it possible to take advantage of the need and priority of connection; preparation of technical conditions for laying new cable lines and modernization of existing networks has begun. Further implementation of the project involves the development of design and estimate documentation, procurement procedures, installation and commissioning, as well as the phased connection of facilities to the newly created energy hub. This approach will ensure increased energy security, sustainability, and efficiency of the community's critical infrastructure, especially in the autumn-winter period and in conditions of possible crisis scenarios.
