The Southern Power Distribution Company Limited (SPDCL) will set up more sub-stations to tide over the overload problems in the city.

The SPDCL has chalked out plans to construct 33/11 KV sub-stations at Mutyalampadu, Durgapuram, Governorpet, and Brindavan Colony soon. The works are likely to commence in August.

The Irrigation Department has parted with some land for the sub-station at Brindavan Colony, and it is likely to ease overload on Bandar Road, a commercial hub.

The proposed new sub-stations will ease the problem temporarily only if the increasing demand is to be considered.

The SPDCL needs to add at least one sub-station every year in the city to meet the growing demand. But, the SPDCL could not take up any move in that direction for various reasons, including non-availability of land, officials say.

Demand increasing

The city requires at least 140 MW of power every day and the demand is ever increasing.

The existing five sub-stations, including the ones at indoor stadium and Mogalrajpuram, in the city are overloaded.

The problem is worse at Ring Road as the consumption is touching 850 amps, crossing the allocated 700 amps.

There is an urgent need for setting up two to three sub-stations to cater to the needs of Patamata and other nearby areas, officials say.

The overloading is leading to frequent tripping of supply and voltage fluctuations as the existing network cannot withstand the load.

The power supply trips automatically if the consumption crosses the permitted limit of 700 amps. But in some sub-stations, it is crossing 850 amps.

Existing network cannot take the load even if the supply matches demand. The city requires more sub-stations and transformers to avoid this kind of problems, officials say.
