In what has come as a shock to the Haryana power generation corporation ltd (HPGCL), the 300 MW unit 2 at Yamuna Nagar thermal power station has come under forced shutdown since the past seven days because of a technical glitch.
Concerned over the flaw, the HPGCL authorities, which prima facie found 'operational negligence', suspended an executive engineer and two assistant engineers on June 6.
According to the information, the unit tripped following an abnormal increase in temperature of turbine bearings. The temperature had risen abnormally, as the lubrication system was not functioning properly, said the officials requesting anonymity.
The work of erection, procurement and construction of this plant was allotted to Reliance Infra Ltd, who further got it done by its vendor company, Shanghai Electric Company of China.
Admitting the tripping, HPGCL managing director Anurag Aggrawal told HT that the extent of damage and time taken to repair the same would be known only after few days when turbine would be opened in the presence of Chinese engineers from Shanghai Electrical Corporation.
He said, “It might take about a fortnight or two to gauge the extent and level of the damage''. “Though, the said snag in the unit is shocking, it will not affect the power supply at all as we have already made long-term power arrangements'', he said.
However, the power utilities had claimed to have made adequate arrangements for 24-hour power supply to cities and a number of rural feeders on urban pattern, the forced closure of this 300 MW unit was not seen as good omen for power utilities before the start of eight-hour power supply for agriculture sector, which was scheduled to start from June15.
While the 600 MW unit of Khedar thermal plant was under shutdown due to low demand, another 210 MW unit at Panipat was non-functional because of a snag in turbine, and 660 MW unit of power plant at Jhajjar was also under overhauling.
The daily power availability from all sources was 1,365 lakh units, a day currently, while the power demand was likely to increase from June 15. Though the HPGCL had adequate power to meet the demand, it would have to make Khedar plant functional in case of further increase in the demand in the coming days, sources held.
