The main objective of the project is to implement energy-efficient technological solutions to reduce primary energy consumption in the district heating system. The measures necessary to achieve the objectives will include the modernisation of the district heating network by connecting the two district heating systems ‘Stefczyk’ and ‘Kościelna’ in Braniewo, the modernisation of individual heat hubs at ul. Bł. Regina Protmann 6, ul. Wileńska 23, ul. PCK 4 and modernisation of the district heating network at Wiejska and Grota Roweckiego streets. The expansion of the district heating network will enable the connection of new customers to the district heating system, this action will enable the liquidation of individual heat sources, which translates into reductions in greenhouse gas emissions in the region. The planned technological solutions related to the modernization of the heating network enable effective supply of heat for heating purposes (central heating), throughout the year to both new and current customers. The use of the designed thermal insulation system will positively affect the financial stability of the company and, as a consequence, will contribute to increasing investment opportunities in terms of energy efficiency, which in turn will translate into reducing gas emissions to the environment. Reducing greenhouse gas emissions to the atmosphere will contribute to improving the state of the environment, implementing the assumptions of the policy of sustainable development of the economy. In a broader context, the implementation of the project contributes to the long-term climate objectives set out in the strategy papers at national and European level. The material scope of this project will include: • Modernisation of district heating networks • Modernisation of district heating hubs • Construction of new and interconnection of district heating networks Accompanying measures This measure includes the purchase of investor supervision services, promotion and information measures including the marking of project documents, e.g.: tender documentation, notices, contracts with contractors, protocols and other documentation created during the implementation and durability period of the project. In addition, it is planned to mark the place of implementation of the project in accordance with the requirements of the grant agreement. The project assumes educational activities in the field of raising environmental awareness of the local community. As part of the educational campaign, all users of the municipal heating network will be instructed on how to use thermostatic valves, they will be familiarized with the subject of waste prevention and recycling and rational use of water resources. The implementation of the investment in question is one of the elements of the implementation of the company’s long-term development strategy towards obtaining the status of an ‘energy-efficient district heating system’ by the applicant. The strategic goal of the company by the end of 2027 is to produce at least 50% of renewable energy, 50% of waste heat, 75% of heat from cogeneration or 50% of a combination (mix) of these sources. In the area of environmental protection and sustainable development, the implementation of the project will translate into: • reducing emissions of pollutants into the air from other heat-producing sources • increasing energy efficiency, thereby reducing greenhouse gas emissions and having a positive impact on climate change globally • reducing the use of non-renewable raw materials (fossil fuels) for heat production by improving the efficiency of existing installations • reducing the risk of pollution-related corrosion of monuments by improving the efficiency of existing installations for heat production • protecting buildings (buildings, buildings, small architecture) from corrosion due to reduced emissions of pollutants by improving the efficiency of existing installations for energy production
