The main objective of the project is to increase the share of renewable energy sources in the Wasilków Municipality. This project envisages the construction of PV installations for local electricity supply and solar collector installations for the purpose of CWU heating for own use of public buildings in Wasilków Municipality, in accordance with the guidelines of Measure 5.1 Energy based on renewable energy sources of the Podlaskie Regional Operational Programme 2014-2020: 1. City Hall in Wasilków, ul. Białostocka 7, 16-010 Wasilków 2. Primary school, st. POLNA 1/4 A, 16-010 Wasilków 3. Primary School No. 1, ul. Adam Mickiewicz 2, 16-010 Wasilków 4. Public Primary School, ul. Supraślska 2, Study, 16-010 Wasilków 5. Kindergarten, st. Sienkiewicza 24, 16-010 Wasilków 6. Kindergarten, st. POLNA 1/4 C, 16-010 Wasilków Ultimately, each individual PV installation should cover up to 100 % of the electricity demand depending on technical conditions and, in the case of solar installations, support CWU heating up to 25 % of the daily demand. At the same time, it should meet the objective of reducing CO2 of min 40 % (PV) and at least 25 % (solar installation), as well as the use of generated electricity of up to 100 % for own use in accordance with the existing technical conditions for installation of the installation. CO2 reduction as well as energy utilisation are considered to be priority conditions. This project will run from 31 May 2019 to 31.12.2020.
