Chennai:
In a bid to cut down on
transmission losses and protect the power grid from blackouts, Power Grid
Corporation of India has tied up with Indian Institute of Technology Kharagpur
to develop high temperature superconducting (HTS) cable.
Power Grid director (projects) I S Jha said that lot of
research in developing superconducting cable is being undertaken across the
world and Power Grid has taken up this research and technology project wit IIT
Kharagpur.
Superconductors are materials that can carry DC electricity
without resistance. HTS cables have the potential to revolutionize the power
delivery industry by reducing costs and maximizing the use of existing conduits
for electric power transmission.
Jha said a usual cable would melt if huge load of power is
transmitted. But HTS cables have the possibility to withstand huge load of
power besides cutting down on transmission losses.
Jha
also said that Power grid is planning to develop a green corridor at a cost of
Rs 34,000 crore. A report has already been submiteed. It would have intra-state
and inter-state component. The report suggests allocation of Rs 21,000 crore
for Intra state and Rs 13,000 crore for inter-state transmission in India.
He
said Tamil Nadu will take up the green corridor project under the intra-state
project component. The wind and solar power will be integrated under the same
grid, he said.
Presently
the total installed capacity in India is about 200 GW.
The
capacity from conventional sources namely coal, gas, diesel,
nuclear
and large hydro amounts to about 88 per cent share and
non-conventional or renewable contribution is about
12 per cent.
