Delay in replacement of runners at Ganguwal, Kotla powerhouses causes Rs 150-cr loss

The alleged delay in the replacement of turbine runners of one unit each at Ganguwal and Kotla hydro powerhouses of Bhakra Beas Management Board (BBMB) have reportedly led to a loss of Rs 150 crore on account of huge generation loss of more than 750 million units.
Ganguwal and Kotla powerhouses of the BBMB are located on the Nangal hydel channel, each having a capacity of 77.65 MW. The 24.2 MW units of each powerhouse were recently renovated and modernised by Bharat Heavy Electricals Limited (BHEL).
However, the runner of 24.2 MW unit no 3 of the Kotla powerhouse failed in August 2013 and the runner of 24.2 MW unit no 2 of the Ganguwal powerhouse failed in September 2013. Both the units remain under breakdown for the past about two years and ultimately the BBMB decided to invite tenders for their replacement.
According to sources, the Nangal hydel channel requires 12,500 cusecs for full power generation at Ganguwal and Kotla powerhouses. Hence, during the months when the water releases from the Bhakra were in excess of 12,500 cusecs, there was power generation loss of 24.2 MW at each of the Ganguwal and Kotla powerhouses. So, the total energy loss up to June 30 is estimated to be more than 750 million units (MUs). Sources said that even at a rate of Rs 2 per unit, the loss to the partner states on account of 751 MU generation loss is assessed at Rs 150 crore.
Sources said that had the BBMB taken up the matter with BHEL at the beginning instead of going for the tender process, BHEL could have been pressed to replace the runners at minimum cost or even free of cost.
BBMB chief engineer (generation) Manmohan Singh Khural said the allotment of tenders for installing the turbine runners in the units of the powerhouses was under process and these would be finalised in a day or two after which the work to replace the runners would start.
About the delay in the replacement of runners, he said since it was government work, they had to consider a lot of things, including the cost to purchase such equipment.
