To ensure uninterrupted and better quality power supply as well as to meet its future requirements, the Chandigarh administration has given nod for undertaking four projects worth around Rs 90 crores.


The standing finance committee chaired by UT adviser K K Sharma has approved the setting up of 66 kilovolt (kv) sub-station at Sector 26 along with underground cable from 66 kv IT park grid sub-station. For this purpose, Rs 37 crore has been allocated.

The committee has also approved 66 kv transmission line with underground cable from Sector 32 to Sector 34 grid sub-station with estimated cost of around Rs 11 crore. Another 66 kv transmission line along with associated 66 kv line bays to upcoming 66 kv grid sub-station at Raipur Kalan at cost of Rs 17 crore and upgradation of 33 kv grid sub-station in Sector 18 to 66 kv at cost of Rs 23 crore have been approved.

UT superintending engineer M P Singh said that all the four projects would help in improving the existing infrastructure. The work on all the projects is expected to start shortly.

There are a total of 13 66 kv sub-stations in the city and each sub-station has a life of 25 years.

As per official record, around six sub-stations have completed the expected life span of 25 years.

MP Singh said that the new sub-station would help them in addressing the problem of overloading of transformers.

A recent study by powergrid revealed that under emergency situations, some of the system elements get critically loaded and therefore there was a need to strengthen the transmission system at various points in the city.

Due to limited land available in the city, the department has decided to opt for gas-insulated sub stations (GIS) technology. This will be the first GIS sub-station of the city.

Outlining the advantages of GIS technology, MP Singh said it requires space 1/10th less space compared to ordinary sub-stations and is more reliable as compared to conventional air-insulated sub-station (AIS) as the number of outages is less. Besides that GIS sub-station is maintenance free and easy to assemble.

220-kilovolt (kv) power sub-station hanging fire

Even one year after getting the nod from the union power ministry’s standing committee on power system planning (northern region), the ambitious project to set up a 220 kv power sub-station is yet to materialise. The electricity department had got the mandatory approval in January 2013.

MP Singh said that the powergrid need to conduct a survey and based on the findings the department would seek allotment of the land required for setting up the station.
