As part of the modernisation of the network, measures are being taken to minimise technical and commercial losses e.e. and to meet growing needs for connection capacities (additional potential). The project concerns the modernisation of the distribution network in the Municipalities: Olecko and Świętojno, among others, in order to enable the connection of new e.e. generation units from renewable sources and is part of the task of type 2 of the rules of the competition dz.4.1 Supporting the generation and distribution of energy from renewable sources. As part of the project, construction works are planned for modernisation of overhead lines — replacing them with 15 kV overhead and cable lines, construction of 15 kV cable connectors, modernisation of trafo station 15/0.4kV, construction of new sections of line nn. The work will be carried out in several stages. Value of works PLN 8683684.89 net (10680932.41 gross), w. qualif. 8683684.89 PLN. The project will allow for connection of new installations of renewable sources of e.e. [energy potential oze project 6.00 MW for 1 year]. Planned connection of new final customers to the planned SN and nn lines — 40 pcs. This project represents the reduction of emissions [24.54 t CO2/r] calculated for the amount of reduced losses in the network. The reduction of unit energy losses for grid modernisation will be 22.28 % (difference in the level of losses before and after modernisation). As part of the project, the SN line 29.92 km (modernisation of existing/construction of new sections) will be modernised and built. The project is consistent with the assumptions (SUERMB), (DSRK — Poland until 2030) and regional — Great Mazurskie Lakes 2020, Economic and Social Development Strategy of Eastern Poland until 2020, SRSG voivodeship. Warmińsko-Mazurskie by 2025. Compliance with environmental objectives and enhanced energy security through the use of renewable energy sources.
