Snags lead to power cuts

Ranchi, March 20: Large parts of the state was today forced to go without power after one unit of Tenughat Vidyut Nigam Ltd (TVNL) developed snags in the small hours of today and had to be shut down for emergency repairs.

TVNL general manager Ramavtar Sahu said the power crisis was likely to continue till tomorrow noon because the unit would remain shut for 36 hours to complete all necessary repairs.

“The unit-II developed snags in its boiler section after the midnight. We have informed the central load despatch centre that we will need 36 hours to complete the repairs. We expect to switch on the unit only after tomorrow noon,” Sahu said.

With two units, TVNL has an installed capacity of 440MW and the generation averages 360-400MW. With one unit down, generation from the TVNL plant was around 170MW today.

Again, only one unit has been working at Patratu Thermal Power Station (PTPS) for the past two days due to ongoing repair work. Patratu thermal station comprises 10 units. But only three have been operational in the recent times. Thus, against an installed capacity of 840MW, the total generation at PTPS varies between 50MW and 160MW on any given day. But for the last few days, with only one unit functional, generation from PTPS grossed 36MW.

Figures released by the Eastern Regional Load Despatch Centre indicated against an average peak time demand of 1,050MW, total generation from the state’s two thermal power plants at Patratu and Tenughat grossed 206MW, leaving a huge gap of 850MW.

Efforts were made to bridge the gap as far as possible by drawing power from the central pool and other outside sources. But the huge gap between the demand and the supply left Jharkhand Urja Vikas Nigam Ltd with no option but to order phase-wise load-shedding across its command areas, spread over 12 out of the 24 districts of the state.
