Following the intervention of the Punjab State Electricity Regulatory Commission (PSERC), the proposed expenditure of Rs. 220 crore on laying new transmission lines has been brought down to Rs. 80 crore, helping a saving of whopping Rs. 140 crore.
The reduction in expenditure became possible after the PSERC ordered fresh study and ground survey by the Punjab State Transmission Corporation Limited (PSTCL) which made proposal for laying new transmission lines.
The Punjab State Power Corporation Limited (PSPCL) bears all expenditure for works carried out by the PSTCL which is further transferred to consumers in the form of power tariff.
Moreover, the PSPCL failed to find out the discrepancy in the PSTCL proposal.
In December last year, the PSTCL sought permission from PSERC to incur Rs. 220 crore for upgradation of three substations at Phari (near Khanna), Hoshiapur and Majra in Mullanpur.
After the fresh survey, it came to light that the transmission lines proposed by the PSTCL were longer, which when reduced to shorter distance, led to considerable cost reduction.
A 220 -KV substation has been planned to provide relief to the transmission system at Gobindg arh while a 220-KV substation has been planned at Majra keeping in view the metro project in Chandigarh.
The Greater Mohali Development Authority (GMADA) has sought an additional load of 900 MVA. The 220KV substation in Hoshiarpur has been planned to provide relief to overloaded system in the area.
These substations will be completed in three years and the work on these will start in the current financial year, with tentative commissioning by 2016-17.
The commission approved the upgradation of 66-KV Phari substation to 220 KV along with loop-in-loop-out one circuit of 220 KV Ganguwal Gobindgarh line. A new substation will come up in Hoshiarpur along with loop-in-loop-out of the 220 KV Nakodar-Rahana Jattan transmission line.
Similarly, for Majra substation, loop-in-loop-out of the 220-KV substation would come up at Ganguwal in Mohali.
The PSERC has also directed both the PSPCL and PSTCL to ensure all the 66 KV works required for disbursal of power from 220-KV substations are as planned and executed in a timebound manner.
