New Delhi, May 9
With the failure of the Centre and Central Electricity Regulatory Commission (CERC) to take any stringent action against the Delhi and UP state power utilities allegedly overdrawing power for the past many days, the north power grid is under serious threat of collapsing any time.

As per the real time data provided by Northern Regional Load Dispatch Centre (NRLDC), at 7.53 p.m. today the frequency of the grid dipped to 48.76 hrtz as against the minimum frequency of 49hrtz required. At 7.50 pm, it had declined to 48.67hrtz, thus affecting the voltage in the region and leading to power cuts in various towns of the region.

As against its scheduled withdrawal of 2501 MW, UP was found to be withdrawing 2963 MW, Delhi withdrawing 1937 MW as against 1913 MW, Haryana drawing 1864 MW against schedule of 1763 MW and Punjab drawing 2434 MW as against 2181 MW quota.

However, Rajasthan, Himachal, J&K, Uttaranchal were drawing much less power as against the schedule thus saving the grid.

Although Power Minister Shushilkumar Shinde is blaming UP for the power crisis in national Capital, but sources said Punjab, Haryana, Delhi are also overdrawing power thus leading to power crisis in Punjab and Haryana besides endangering the power grid itself.

Punjab had registered its protest to the Power Ministry claiming that due to overloading of the transmission lines, it was unable to evacuate 1200 MW from the eastern states, though it has entered into financial contract with them. “We are only able to evacuate 600 MW as against 1200 MW contracts, due to overloading of transmission lines,” Punjab Chief Secretary K.R. Lakhanpal has said.

After complaints by Northern Regional Load Dispatch Centre (NRLDC) states and Power Ministry, the CERC today imposed a penalty of Rs 1 lakh on Uttar Pradesh Power Corporation Ltd. (UPPCL) for an unauthorised over-drawal from the Northern Grid even when the frequency was below the threshold level of 49.0 Hertz.

As per the Indian Electricity Grid Code (IEGC), the states are required to curtail their over-drawal in order to prevent a grid collapse if the frequency falls below 49.0 Hertz.

The sources said such a nominal penalty would not have any desired impact on the power scenario in the region, already facing a power deficit of 4000 MW.

Several areas go without power
Tribune News Service

Ropar, May 9
Many cities and rural areas in the state remained without power since last night when all units of thermal plant, here became non-functional due to a fault in transmission lines caused by rain and storm. Sources say non-functioning of six units of the plant caused loss of 300 lakh units to the state.

PSEB sources said the power crisis came to notice when the transmission line of 220 KV from Ropar to Jamsher got damaged at 10.30 pm last night due to rain and heavy wind. As a result the five functional units, each of 210 MW, of the plant, came to a halt. While one unit of the plant was already shut down for annual maintenance.

As thermal plant stopped generation, many areas of the state like Ropar, Gobindgarh, Ludhiana, Nawanshahr, and Mohali faced power black out till morning, sources added. Power shortage also surfaced in Chandigarh when a fault was detected in the transmission line of the city linked with Punjab grid last night.

Sources said the power crisis continues to persist in the state as only three units of the plant, had become operational till 6 pm and two continued to be closed. Tower of the transmission lines suffered damages last night and some of the areas still did not get supply of power. General Manger of the plant, N.K Arora, said three units each of 210 MW have become operational while the remaining two units will become operational very soon.
