Commissioning shall not take so long as all the major contracts for construction of WDFC (1500kms+) have already been awarded to contractors and about 92% contracts for EDFC (Ludhiana-Sonnagar 1300+km) have been awarded.
It is expected that that above shall be fully commissioned in phases 3-5 years.(although the target is yr 2019/20 which is likely to be extended by an year or two)
For other 4 DFCs planned it will take much longer as funds have not been arranged for the same.
