Andrey Mayorov, First Deputy Director General and the Chief Engineer of Rosseti, has reported about the progress of repair operations in the North Caucasian Federal District at the meeting in Magas chaired by Evgeniy Grabchak, Deputy Minister of Energy of the Russian Federation.

Early in October, the maintenance and repair program works were delivered by 109% of the schedule. The main equipment operations were completed.

Over the nine-month period, Rosseti has reduced the failure rate at 110+ kV electric power networks by 10% as compared to the corresponding rate in 2017.

135 ice-melting tests were conducted on overhead power transmission lines, a pool of standby equipment was set up, 156 emergency power supply sources were prepared (9.345 MW in total), and emergency reserve sets for Chechenenergo and Dagenergo were completed.

Several milestones of the investment program will be reached this year in the regions of the North Caucasus; in total, 1,262 MVA of transformer capacity and 703 km of power transmission lines will be put into operation.

Key projects:

·       500 kV overhead line Nevinnomyssk – Alania and the 500 kV Alania substation installed to transmit the power generated by Rostov Nuclear Power Plant and Stavropol Water Power Plant to the North Caucasian power grid systems

·       Construction of the main 330 kV transit line Artem – Derbent, refit of the 330 kV Derbent substation with capacity augmentation from 250 to 400 MVA

·       Installation of the second 125 MVA autotransformer at the 330 kV Artem substation to make good the power deficiency

·       Completion of installation of the 110 kV overhead power line Grozny Thermal Power Plant – Plievo Novaya with installation of a short-circuit point for ice-melting to transmit the power generated by the Grozny TPP

·       Refit of the 110 kV Golovnaya substation for technological connection of the Ust-Dzheguta Small Water Power Plant

·       Refit of the 110 kV Yuzhnaya substation with replacement of two transformers.
