The group of companies "Indastek" started detailed design of 220 kV "Annunciation — Varvarovka, calling at 220 kV switchyard Tambovka (Cranes)." Work carried out in the framework of the investment project to increase electric grid complex energonadezhnosti East Amur region, where the construction of the cosmodrome "East". Construction Customer — JSC "FGC UES".
According to the representative of the group of companies "Indastek" Edward Anan, "At the moment, is working documentation and procurement of major equipment. For construction works union plans to start in March of this year. "
