Joint Stock Company «Ternopiloblenergo» originates from low-power thermal, diesel and hydropower plants installed during the Austro-Hungarian and Polish periods for illumination of county towns, villages and Ternopil city centre. The key stages of «Ternopiloblenergo» electric power grid development include: 1958 — start of construction of small hydroelectric power plants on Siret and Zbruch rivers and electrification of agricultural segment; 1962 — the beginning of electrification of agricultural segment using the state power grid, 1970 — completion of electrification in the Ternopil region. Core business of «Ternopiloblenergo» includes intake, transmission, distribution and supply of electric energy to the consumers in Ternopil region.
In parallel to the core activities, Ternopil regional energy complex provides reliable, quality power supply, introducing new investment and innovation projects, and enhancing economic efficiency of the segment. The Company's assets include:
- 20,735 km of overhead transmission lines and 949 km of 0.4 - 10 kV cable lines;
- 2,245 km of 35 - 110 kV overhead power lines;
- 5,656 transformer substations 10 / 0.4 kV and 10 kV distribution stations, total capacity of 978.8 MVA;
- 153 transformer substations 35 - 110 kV, total capacity of 1,133.4 MVA.
The Company targets increasing consumer service levels, building friendly relations and creating comfortable conditions for electricity utilisation, achieving 100 % payments for consumed electricity. The Company is currently engaged with the following technologies and projects:
• reconstruction of 0.4 — 10 kV electric grid using self-supporting insulated conductors (SIC);
• replacement of the existing oil-insulated circuit-breakers with vacuum or SF6 circuit-breakers at 35 -110 kV transformer substations;
• replacement of porcelain insulation with polymer insulation at 35 - 110 kV overhead transmission lines;
• implementation of «Diamond» type microprocessor protection, «Regina» type fault recording systems and UZA 10A-2 Relay Protection and Automation at 35 - 110 kV substations;
• implementation of thermal control equipment;
• introduction of the automated system of commercial electricity metering (ASCEM);
• implementation of corporate communication system based on modern digital radio-relay stations and automatic exchanges;
• using XLPE cables for further development of 10 kV cable networks.
