Almost a month after the Beas tragedy that left 24 engineering students dead, the state government probe gave a clean chit to the state load despatch centre (SLDC), working under the ambit of Himachal Pradesh electricity board.
The SLDC had ordered the Larji dam officials to close down the generation of power. Subsequently, the release of water from the dam swept away the 24 students and a tour operator from Hyderabad on June 8.
The state government had ordered a probe to ascertain the role of the SLDC in the tragedy on the suggestion of Mandi divisional commissioner Onkar Sharma to the Himachal Pradesh high court.
Chief engineer, directorate of energy, Neeraj Kapoor on Saturday submitted a report, comprising three volumes, to principal secretary of multipower projects SKBS Negi.
The report concludes that the high water level led to more generation, forcing the SLDC to ask five power projects to close down their generation on the fateful day.
When water was released from Larji dam, the SLDC had asked power projects, including the Giri project of 60MW, Bhawa of 4.5MW and Baspa of 325MW to shutdown generation.
The report said that the SLDC had adopted a laid down procedure to convey the message received from the Northern Region Load Despatch Centre (NRLDC) as the frequency was more in the dams.
The report clearly states that the SLDC had asked all power projects under its purview to close down generation as the frequency had increased in the grid.
Frequency in the grid should not increase more than 50 Hertz, while it should not fall below 49.7 htz as the variations could adversely impact the grid.
In his report, Kapoor stressed upon the need for improving the understanding between SLDC and Northern Region Load Despatch Centre (NRLDC). “We have received the report and the action would be taken as per the recommendations in the report,” said principal secretary MPP SKBS Negi speaking to Hindustan Times.
The divisional commissioner Mandi detected that the SLDC on June 8 had asked the Larji hydro project and Bhabha hydro projects to shed load.
