Sayano-Shushenskaya Hydro Electric Power plant was completely restored

Sayano-Shushenskaya Hydro Electric Power plant was completely restored.

Launching of SS HEP was held with the participation of Igor Sechin, the head of "Rosneft" , who was the leader of the legal committee of HEP restoration, as well as Evgeny Dod, the head of "Rushydro". Launching of the final hydraulic unit means that HEP is completely restored after more than five years of repair works and it can maintain output at full capacity. The full capacity which Sayano-Shushenskaya HEP can reach again is 6.400MW. With this index the hydro electric power plant ranks the 13th place in the world. After the restoration hydraulic units are equipped by new system of technological protection, which will stop unit operation in case of emergency. Maximum unit efficiency is 96.6% and operating life is 40 years. It is worth to mention that BPA Company is a partner of HEP for a lot of years.

One of the projects is BPA Company completely restored low voltage packaged transformer substation 0,4кВ andswitch gear 6 kV of Sayano-Shushenskaya HEP named after P.S. Neporozhniy. The customer of this kind of restoration was JSC "Rushydro". The place of operation was the building of SS HEP. The delivery of equipment, units and materials, removal of equipment was achieved as well as construction-assembly work of new equipment – power transformers (1000kVA и 630kVA), low voltage boards of modular type, distributing point, boards with circuit breakers,switch gear 6 kV (switch gearwith drawout circuit-breaker and microprocessor units RPEA), power cable and control cable. Start-up and adjustment work with high-voltage testing of the unitsincluding the reports of electric laboratory was performed.

The complex testing of the mounted equipment was arranged; as-builts for the mounted equipment of SS HEP were prepared and approved by the inspection board. As the result of cooperation of SS HEP, BPA and other companies who took part in restoration, the condition of water development facilities of Sayano-Shushenskaya HEP and the level of their maintenance level meet all technical requirements.
