New Delhi: The Power Ministry will soon start making public details about progress made in strengthening electricity grids that is aimed at preventing instances like the recent grid failures.

The seven-member panel, chaired by Central Electricity Authority chairman A S Bakshi, in its report on failure of grids on July 30 and 31 has suggested a slew of measures to boost the performance and security of grids system.

The twin grid failures on July 30 and 31 had impacted more than half of country's population.

A senior government official said the panel's recommendations, including ways to prevent "undesirable operation" of electricity grids, are being considered seriously by the Power Ministry.

In a recent meeting, the Ministry took the decision that progress of the recommendations made by the committee would be made public. The updates are likely to be made public on a monthly basis, the official told.

The panel, set up by the Power Ministry, had observed that "no single factor" was responsible for grid disturbances on July 30 and 31.

In its report submitted to the Power Ministry last month, the panel had suggested an extensive review and audit of the protection systems to avoid their undesirable operation.

Prevention of overdrwling of power from grid

Aimed at preventing the practice of overdrawl from the grid, the committee had also emphasised the need to review penal provisions (under 2003 Electricity Act) to "ensure better compliance of instructions of Load Desptach Centres and directions of Central Commission".

Load Despatch Centres are responsible for real time monitoring the frequency and flow of electricity in the grids. Another panel suggestion was granting more autonomy to all Load Despatch Centres so that they can take and implement decisions relating to operation and security of the grid.

"To avoid congestion in intra-State transmission system, planning and investment at state level need to be improved," the panel had said. Further, there was a recommendation for having a separate task force involving experts from academics, power utilities and system operators -- to carry out a detailed analysis of present grid conditions as well as anticipated scenarios that could lead to disturbances.

"The committee may identify medium and long term corrective measures as well as technological solutions to improve the health of the grid," the report had said.

To provide power supply for essential services when there is a grid failure, the panel has proposed islanding scheme. "Efforts should be made to design islanding scheme based on frequency sensing relays so that in case of imminent grid failure, electrical islands can be formed.

"These electrical islands can not only help in maintaining supply to essential services but would also help in faster restoration of grid," the report had noted.

Considered one of the worst power crises in the world, the failure of Northern, Eastern and North Eastern grids on July 31 affected more than half of country's population.

The massive collapse happened less than 24 hours after the Northern grid snapped and was revived on July 30. India has five electricity grids Northern, Eastern, North Eastern, Southern and Western. All of them are inter-connected, except the Southern grid.
