Union Minister of State for Power (I/C) Shri Jyotiraditya M. Scindia, dedicated the 1200 kV Ultra High Voltage (UHV) AC National Test Station of Power Grid Corporation of India Limited (POWERGRID) to the Nation today. The world’s highest voltage level, 1200kV UHVAC sub-station is located at Bina in Madhya Pradesh.
It is an outstanding International achievement in high voltage power transmission.
The project involves a unique Public Private Partnership (PPP) model, where all the UHV equipments have been developed indigenously by a consortium of 35 Indian power equipment manufacturers in association with POWERGRID, who provided
the necessary resources and basic system design & specifications. The private manufacturers have created suitable facilities to design & manufacture 1200 kV equipments for the test station.
The test station is an important milestone in development of India’s electric power transmission. This will facilitate transfer of bulk power from remotely located generating stations to long distance load centers.
This innovation will also result in saving of huge Right of Way (ROW), minimize impact on flora & fauna and will ensure cost effective bulk power transmission corridors in the country. One 1200kV Single Circuit line is expected to transmit 6000 to 8000 MW power, thereby offers higher power transfer capacity per meter of ROW in comparison to 400 kV and 800kV transmission system.
Further, due to indigenous development of equipment / materials, the system will give a strategic advantage besides cost economy and timely Operation & Maintenance.
POWERGRID a ‘Navratna’ Company and the ‘Central Transmission Utility (CTU)’ of the country is at present operating more than 96,000 ckt. kms. of transmission lines along with 159 Sub-stations having a transformation capacity of over 1,51,000 MVA. With the use of state-of-the-art preventive maintenance techniques, average availability of transmission system is consistently maintained at 99.9%. The Inter-regional power transmission capacity of National Grid today is about 28,000 MW.
