The UP government has denied any role of the state in the collapse of the Northern and Eastern power grids that occurred Tuesday afternoon. The massive failure crippled the entire state for several hours second time in two days.
The Northern grid had collapsed Monday as well with the Centre holding overdrawing of power by UP,Punjab and Haryana responsible. The UP government promptly removed UPPCL Chief Managing Director Avinash Awasthi.
Through a press release,UPPCL chairman Anil Kumar Gupta denied any role of UP in the grid collapse. Taking into consideration the parameters at the time of grid failure,there is no reason to believe that any power operations in UP triggered it, Gupta said. Power officials today said the grid collapsed around 1:02 pm
Gupta said power swing was suspected on account of some transmission line tripping that caused grid failure. Further investigation was required to ascertain the real cause,he added.
According to officials,UPs power system was stable without any emergency condition or any known abnormality before the failure of grid. The grid frequency,which should be in the range of 49.5 and 50.2,was 49.7.
Overdrawal at that time was bare minimum at 40 MW. The ex-bus generation from UP Rajya Vidyut Utpadan Nigam Limited thermal power stations was around 2200 MW and scheduled supply from central sector was only 3,339 MW.
Officials claimed there was no violation of Total Transfer Capability or Available Transfer Capability and that means there was no imbalance in grid parity in the state.
