Union Minister of State for Power Jyotiraditya M Scindia dedicated Power Grid Corporation of India Ltd's (PGCL) 1,200-kV ultra high voltage (UHV) AC national test station to the nation on Wednesday.
The world’s highest voltage level, 1,200-kV UHVAC sub-station is located at Bina. Madhya Pradesh.
The project involves the public private partnership (PPP) model, where all the UHV equipment has been developed indigenously by a consortium of 35 Indian power equipment manufacturers in association with PowerGrid, which provided the resources and basic system design & specifications.The private manufacturers have created suitable facilities to design & manufacture 1,200 kV equipments for the test station.
The test station is an important milestone in development of India’s electric power transmission. It will facilitate the 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), minimise the impact on flora and fauna, and ensure cost-effective bulk power transmission corridors in the country. One 1,200-kV single circuit line is expected to transmit 6,000 to 8,000 mw power, offer higher power transfer capacity per meter of ROW icompared to 400 kV and 800kV transmission systems. Further, due to the indigenous development of equipment/ material, the system will give a strategic advantage besides cost economy and timely operation & maintenance.
PowerGrid, a ‘Navratna’ company and the country's central transmission utility (CTU) is at present operating more than 96,000 ckt km 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, the average availability of the transmission system is consistently maintained at 99.9 per cent.
The inter-regional power transmission capacity of the National Grid today is about 28,000 mw.
