500 kV Yenisey substation
In April 2011 Stroytransgaz concluded a contract with FGC UES JSC for the greenfield construction of the 500 kV Yenisey substation with 500 kV HV and 220 kV HV branch lines. Stroytransgaz will carry out detail design, procurement and construction work.
The works comprise the construction of more than 30 km of 10 kV, 220 kV, and 500 kV HV lines, and putting into operation 1,602 MVA of transformer capacity as follows:
- Construction of a 500 kV outdoor switchgear
- Construction of a 220 kV outdoor switchgear
- Parking house construction
- Support building construction
- Warehouse construction
- Substation control building construction
- Relay panel building construction
- Construction of 220 kV and 500 kV branch lines
- Construction of 10 kV HV lines
- Upgrading of 110 kV and 220 kV HV lines
- Installation of seven phases of AT 500/220/10 kV (one standby phase) of 1602 MVA (6*267 MVA) total capacity
The 500 kV Yenisey substation is located in the central part of the Krasnoyarsk Krai and is maintained by the Krasnoyarsk Power Grid Company, a branch of FGC UES JSC. The project aims to enhance the reliability of power supply in the Krasnoyarsk Krai, and to ensure the growing needs in power supply of industrial facilities, including iron and steel plants.
Since 2011 to 2014 the 500 kV Yenisey substation is planned to be integrated into the unified power grid by two stages.
