Ukrenergo has signed a contract with the Indian company Kalpataru Power Transmission Ltd for the reconstruction of 330 kV overhead lines including the replacement of a lightning protection cable with an optical ground wire. This is the first, linear part, of the project for the FOCL southern ring construction to be implemented as part of the Development Concept of the NPC Ukrenergo telecommunications network approved in 2019.
Under the contract, fibre-optic communication lines (FOCL) will be installed on twenty 330 kV overhead lines with a total length of 1,375 km in 10 regions of Ukraine (Kyiv, Vinnytsia, Kirovohrad, Cherkasy, Poltava, Dnipropetrovsk, Zaporizhia, Kherson, Mykolaiv, and Odesa).
The contract provides for the “turnkey” construction of the linear part of the project: from design (detailed design documentation phase), supply of necessary equipment, construction and installation to commissioning of the FOCL linear part. Work will commence once the detailed design is developed by the contractor and approved. Given the scale, the project will be completed in 2024.
The contract value is 14.15 million euros (excluding VAT). The funding source is loan funds of the European Investment Bank (EIB) saved during the implementation of the investment project for the construction of the 750 kV OHL Zaporizhia NPP–Kakhovska.
It should be noted that during international competitive bidding, 6 proposals were received from companies from 5 countries – Poland, Kazakhstan, Turkey, China, and India. Through competition among bidders, the purchase price decreased by 35% compared to the estimated cost. As a result, almost 7.5 million euros of EIB loan funds were saved.
In parallel, it is planned to implement the second, station part, of the project for the construction of the FOCL southern ring, which provides for the installation of DWDM (Dense Wavelength Division Multiplexing) equipment at 36 facilities of Ukrenergo and adjacent generation facilities. Preparations are currently underway for international competitive bidding for the equipment installation. The second part of the project usually requires a much shorter time for implementation, so the linear and station parts of the project will be completed synchronously.
Fibre-optic communication lines will ensure high reliability of office and process data transfer between the Company’s facilities and with the generation, in full volume and with guaranteed high speed. After all, the key advantages of fibre-optic communication lines with DWDM equipment are the high optical fibre bandwidth, information transfer speed of up to 400 Gbps, as well as insensitivity to the electromagnetic interference of overhead power lines.
The project will deliver our own backbone network of high-speed process and office communication, which is currently provided mainly through leased communication channels in these regions. As of today, Ukrenergo has built more than 2.5 thousand km of own fibre-optic communication lines, which is almost 25% of the Company’s communication network.
Building own fibre-optic communication lines in the central and southern regions, as well as the connection of existing FOCL sections in Kyiv–Vinnytsia–Lviv–Kremenchuk and Kharkiv–Donbas, will make it possible to have a single optical network, which will form the basis for the further development of modern telecommunications in the IPS of Ukraine.
In addition, the use of fibre-optic communication lines will significantly increase the level of monitoring of the equipment performance at the Company’s power facilities, facilitate instantaneous tracking of any deviations in the network operation and prevent process disturbances. In the market conditions and the context of the future integration of the Ukrainian power system into ENTSO-E, this is an essential component in the technological complex of operational control of the power system, its resilient and stable operation.
It will be recalled that it is the third contract in the history of Ukrenergo’s cooperation with Kalpataru Power Transmission Ltd. Earlier, the Indian company successfully built the OHL 750 kV Rivnenska NPP–Kyivska and diversions of OHL 330 kV Chornobylska NPP–Pivnichna at the 750 kV Kyivska substation.
