Hiccups on power generation front in State

In the past one week, power generation in the State has come down drastically owing to the shutting down of three units out of seven at the Raichur Thermal Power Station (RTPS) and the shutting down of 13 units out of 33 at various hydel power stations.

With an installed capacity of 1,470 MW (7x210 MW), the RTPS has a generating capacity of 35 million units a day. But with functioning of only four units, the generation has come down to 14.51 mu per day.

All the major hydel power stations in the State, which have an aggregated installed capacity of 3,500 MW, generating about 28.61 mu of power per day as against the normal generation between 40 mu and 45 mu during monsoon. About 13 hydel units (of different capacities) out of 33 units at some major hydel stations have been shut down since a long time for one reason or the other.

Out of seven units at RTPS, only four units are functioning. The second unit was shut down from July 15 for an annual maintenance and the unit is expected to be commissioned by September-end. The fourth unit was shut down on August 3 following a leakage found in copper tubes in its boiler section. The unit is expected to restart operation by Saturday.

The sixth unit was shut down from July 30 for the annual maintenance and the unit is expected to become operational by August 15. Meanwhile, the 250-MW eighth unit, which was synchronized last month, is expected to start commercial operation only after August 15. Among the hydel power stations, three units out of six are in operation at the Nagjhari Power House, two units out of four are in operation at the Varahi Underground Power House, nine units out of 10 are in operation at Sharavathi Generation Station, two units out of five are in operation at the Bhadra Hydro-Electrical Power House and one unit out of two are in operation at the Mani Dam Power House.

Supply and demand

At present, the average power generation in the State stands at 50 mu per day, including the 22 mu from the thermal plants (RTPS 14 mu and BTPS 7 mu), 28.60 mu from the hydel station and 1.15 mu from the diesel generation set, and another 60 mu of power is being imported from the central grid taking the total availability of power in the State to 112 mu per day. Whereas, the power demand in the State stands at 140 mu per day.

The situation has forced the Karnataka Power Transmission Corporation Limited (KPTCL) to cut down the minimum allotment of power to various power supply companies in the State. The KPTCL has directed them to limit the power utilisation within the allotment made to them by imposing unscheduled power shutdown in their respective jurisdictions.

So the Gulbarga Electricity Supply Company (GESCOM) has been imposing three to four hours of unscheduled power shutdown every day in its jurisdiction for the past three days.
