Government turns down TNEB’s proposal

T. Ramakrishnan

To reduce duration of power supply for the farm sector

CHENNAI: The State government, while giving its approval for “power holiday” for cities and towns and zonal holidays for industry, has turned down the Electricity Board’s proposal for reducing the duration of power supply for the farm sector.

According to the proposal, the six-hour supply during day would be reduced to four hours. This would save nearly 700 megawatt daily, says a source.

At present, the farm sector is divided into two groups. From 6 a.m. to 12 p.m, one group is given three-phase supply and the other single phase supply. The situation changes the other way between noon and 6 p.m.

Had the proposal been implemented, the farm sector would have been split into three groups. While one group would get three phase supply for four hours, the second group would receive single phase supply during the period and the third group would go without the supply.

When the proposal came up for consideration, the government decided not to disturb the present arrangement for five days in a week.

Only on two days, the farm sector would have four-hour supply, the sources say. Those two days would vary from place to place. For example, in Chengalpattu circle, farm connections would have four hours’ supply on Sundays and Mondays. In Villupuram region, this would be on Tuesdays and Fridays.

Talking of the failure of southwest monsoon, another source points out that the present storage of hydro stations is almost one-fourth of the storage last year.

The storage, expressed in terms of million units (MU) of possible energy generation, was about 576 MU on Saturday morning against 2,188 MU on the corresponding day last year.

Inflow was a meagre six MU whereas it used to be at least 100 MU during the same period in previous years, the sources say.

Since April, the hydro generation (as on date) accounted for about 1,540 MU while it was 1,210 MU between April and the elapsed period of July last year.

In view of the current crisis in the southern region, the technical coordination panel of the Southern Regional Electricity Board held its meeting at Bangalore a few days ago and reiterated that the frequency of the region’s grid should be maintained in the range of 49 to 50.5 cycles. [The standard frequency of operation is 50 cycles.]

Big jump

As all the southern States are witnessing a big jump in their demand, each State tries to overdraw from the system. As a result, the frequency, on many occasions, goes down below the permitted levels.

Though the region has not experienced any major disruption, power managers are concerned over the trend.

The sources say that on Saturday, the frequency position was fairly better in view of steep fall in demand following rains in parts of the southern region.
