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.
