(a) whether the Government propose to formulate a scheme to inter-link all the power grids with one another in the country;
(b) if so, the details thereof;
(c) the estimated expenditure likely to be incurred thereon;
(d) the sources of funds proposed to be mobilized; and
(e) the time by which the scheme is likely to be implemented?
THE MINISTER OF POWER ( SHRI P.M. SAYEED )
(a) & (b) : A plan has been chalked out for development of a National Power Grid
through integration of all the regional transmission systems in the country. The present
inter-regional transmission capacity in the country is 9,500 MW which is likely to
increase to over 30,000 MW by 2012. A list of the existing inter-regional transmission
lines and those under construction/planned for completion by 2012 is at Annex.
(c) & (d) : An investment of around Rs. 70,000 crore has been envisaged in the
Central sector in 10th and 11th Plans on intra-regional and inter-regional transmission
lines for development of the National Power Grid. The required funds will be mobilized
through internal resources of PGCIL, domestic loans and external commercial
borrowings by PGCIL, budgetary support to PGCIL and investment from private sector.
(e) : Integration of regional grids is a continuing process. In addition to the inter-
regional transmission lines which have been planned for completion upto 2012, more
inter-regional and intra-regional links may be required depending upon the generation
addition and power flow requirement.
