The project consists of mounting renewable energy sources on private buildings in municipalities: Policzna, Chotcza, Garbatka-summer and Kazan. The main objective of the project is the efficient use of energy from renewable sources in 4 municipalities: Policzna, Chotcza, Garbatka-summer and Kazanów contributing to the creation of environmentally friendly infrastructure. The objectives of the project are related to the use of alternative energy sources by residents of 4 communes, which is connected, among other things, with the improvement of air quality in the region and, therefore, are consistent with the objectives of the Regional Operational Programme of Mazovian Voivodship for the years 2014-2020. The following results will be achieved as a result of the project: Production of electricity from newly built/new RES-based installations – 467,53 MWhe/year, Production of heat from newly built/new RES-based installations – 3 302,33 MWht/year. Estimated annual decrease in greenhouse gas emissions (CI34) – 1 876,28 [tonnes of CO2 equivalent/year]. Production of heat from new generation capacity of RES installations 3 302,33 MWht/year. Production of heat from newly built RES installations 3 302,33 MWht/year. Production of electricity from newly built installations using RES 467,53 MWhe/year. Production of electricity from new generation capacities of installations using RES 467,53 MWhe/year. Products: Additional generation capacity from renewable sources – 3,26 MW; Additional renewable electricity generation capacity – 0,48 MW; Additional capacity to generate heat from renewable sources – 2,78 MW; Number of built units of electricity generation from RES – 98 pcs. Number of built units of heat generation from RES – 378 pcs. The target group of the project will be residents of 4 Municipalities Policzna, Chotcza, Garbatka- Summer and Kazanów.
