Work on laying 110 kV underground feeder cables from the 220 kV Ayathil substation to the upcoming 110 kV gas insulated switchgear (GIS) substation of the KSEB at the Power House complex in the city will commence on Thursday.
In order to facilitate the work, there will be traffic restrictions on the Kollam-Ayoor KSTP road from Chemmamukku junction to Ayathil junction from Thursday.
Under the restrictions to be implemented in association with the city traffic police, vehicles reaching Ayathil junction to proceed towards Kollam city through the KSTP road will have to take a deviation from Ayathil from Thursday till further notice. Under the restrictions, parking of vehicles will also not be allowed from Chemmamukku junction to the Ayathil power house. The KSEB authorities here have called upon the people to cooperate with the restriction. Work on the GIS substation was inaugurated by Electricity Minister Aryadan Mohammed on May 15 last year. At that time, the Minister had called for the cooperation of the people when it came to laying the underground feeder lines. He said that though the schedule is to commission the substation within two years from May 2015, it could be commissioned even in 18 months if the people readily cooperated with the works pertaining to the laying of the underground feeder lines.

The KSEB authorities said the 40 mega volt ampere (MVA) capacity GIS substation is coming up at a cost of Rs.43.69 crore. The substation is being constructed on the basis of the calculation that the power demand in Kollam city was growing at the rate of 7 per cent annually. The GIS substation will stand on 47 cents of land.
The current power requirements of Kollam city is met from the Ayathil and Kavanad substations through seven 11 kV feeders with a capacity of 30 MVA. With the commissioning of the GIS substation, Kollam city’s power position will be added by nine 11 kV feeders with a capacity of 40 MVA.
The advantage of the substation is that it requires only one-tenth of the land area required to accommodate traditional sub stations of the same capacity.
