The Commercial Court of the Odesa oblast has returned Ukrenergo the Ukrainian section of the 750 kV interstate high-voltage overhead line Yuzhno-Ukrainska NPP – Isakcha (226 km of power lines). Previously, it served as a contribution to the joint venture agreement between Ukrenergo, the Southern Energy Company Consortium (Odessa) and EMFESZ Kft (Hungary).
The return of the 750 kV line Yuzhno-Ukrainska NPP – Isakcha will allow Ukrenergo to begin work on a project of common interest with the EU Energy Community (Project of mutual interest, PMI) for construction of 750/400 kV Primorska substation with interstate 400 kV OHL Primorska – Isakcha. The project will increase the capacity of the interconnector with Romania to 1000-1200 MW, strengthen the reliability of electricity supply in the south of Ukraine and Moldova, and remove restrictions on RES generation capacity in this region.
The feasibility of renewing the 750 kV transmission line Yuzhno-Ukrainska NPP – Isakcha with changing its voltage to 400 kV (750 kV voltage is atypical for ENTSO-E networks) was established in the course of studies of the integration of electricity networks and electricity markets of the Black Sea region supported US Energy Association (USEA). The project is supported by the Romanian TSO Transelectrica.
The estimated cost of construction is €226 million financed by IFIs. The Project is to be completed by 2026.
Earlier, the transmission line became the company’s contribution to joint activities with the aim of renewing this interstate power line to expand the export possibilities. However, due to the Consortium’s inactivity, the transmission line has not been renovated, and most of it was damaged.
At the same time, the line remains the state’s property under the management rights of NPC Ukrenergo, and the company has all the necessary permits to use the land along the route of the line.
