The aim of the project is to increase the security and reliability of the electricity distribution network and ensure uninterrupted supply of electricity to customers. The objective is to modernise transformer substations and distribution points using smart technologies. The planned activities of the project are: — Upgrading of transformer substations (Pakruojo TP 110/35/10 kV; Pabradė TP 110/35/10 kV; Parvėjos TP 110/35/10 kV; Sendvario 110/10 kV TP; Švenčionys TP 110/35/10 kV; Sedos TP 110/35/10 kV; Paberze 110/35/10 kV TP; Druskininkai 110/10 kV TP, Vilkpėdė TP). —Modernisation of distribution points (SP-3 in Vilnius; SP-950 in Kaunas during the destruction of SP-353; SP-6 in Šiauliai; SP-256 in Kaunas; SP-7 in Klaipeda; SP-2 in Telšiai; SP-935 in Kaunas; SP-2 in Kretinga; SP-5 Druskininkai.). The main factors behind the project are the ageing of 110/35/10 kV and 35/10 kV transformers, the ageing of 10 kV distribution points, the low automated management of the medium-voltage grid, the aim of increasing the reliability of the electricity distribution network, energy efficiency while reducing CO2 emissions. The TP and SP to be reconstructed are in a different state, but they are not suitable for any facility and do not meet the requirements of a “modern” substation or distribution station. Some of the objects use old analogue relay protection, when microprocessor relays/controllers are currently installed in newly reconstructed facilities, i.e. programmable industrial computers and transformers with reduced technological losses are being built, smart metering is being implemented to remotely scan the distributed and substation electricity used for its own use. Parts of metal and reinforced concrete structures are outdated/worn, which need to be replaced with new ones in order to reduce the number of possible mechanical failures associated with mechanical stress and corrosion.
