The grid lines are associated with the 1,600 MW Parbati hydro power project and 800 megawatt Koldam hydro project in Himachal Pradesh.

PGCL's directors approved the proposal last week. The issue will now be referred to the Central Electricity Regulatory Commission for final clearance, PGCIL Chairman and Managing Director R.P. Singh said.

While the 800 MW Koldam project is being built by National Thermal Power Corp. Ltd., the 1,600 MW Parbati valley project is being constructed by National Hydroelectric Power Corp. Singh said PGCIL had cleared the western region system strengthening project in Maharashtra and Gujarat states.

The project would be a joint venture between PGCIL and REL, Singh said.
