Ranchi, 13 other districts in dark

Ranchi, May 12: Fourteen of the state’s 24 districts had to endure prolonged power cuts in the peak of summer today after a TVNL unit was forced to shut down following a snag.

According to Ramavtar Sahu, general manager of Tenughat Vidyut Nigam Ltd at Lalpania in Bokaro district, the situation is likely to improve only by tomorrow afternoon.

The shutdown meant an overall deficit of over 300 MW, despite drawing from DVC and the central pool. This left the state power board, Jharkhand Urja Vikas Nigam Ltd (JUVNL), no option but to enforce blackouts throughout command areas spread over Ranchi, Gumla, Lohardaga, Khunti, Simdega, West Singhbhum, Seraikela-Kharsawan, Latehar, Chatra, Garhwa and Palamau districts, in phases.

Even the state capital was not spared as all sub-stations in Ranchi resorted to limited load shedding to match supplies with demand.

Sahu said the TVNL unit would be restarted tomorrow only if repairs were completed by this evening.

“We were forced to take the measure early this morning following snags in the boiler section of Unit 2. Necessary repairs have begun. We expect to complete repairs by late this evening so that we can light up the unit early tomorrow,” Sahu told The Telegraph over phone from Lalpania.

Normal power supplies could be expected by tomorrow afternoon after the unit is re-synchronised into the state grid.

TVNL, equipped with two units, has an installed capacity of 420 MW. However, following the shut down of one of the units, generation from TVNL has come down to a paltry 175 MW.

Figures released by eastern load despatch centre indicated that following the shut down of a TVNL unit, total generation in the state plunged to a low of 275 MW against a peak time demand of over 1,050 MW.

While TVNL was generating 175 MW against its installed capacity of 420 MW, another 100 MW was being contributed by Patratu Thermal Power Station at Ramgarh district.

To meet the demand-supply gap, JUVNL was drawing around 340 MW from the central pool. Another 100 MW was being contributed by DVC.

However, an uncovered deficit of over 300 MW left JUVNL with no option but to enforce blackouts throughout its command areas, including Ranchi.
