AP Transco has stepped up daily power purchases from outside sources to a high of 26 million units to compensate for the loss suffered by the grid following withdrawal of several power stations due to various reasons, including voluntary tripping for annual overhauling.

Till recently, the purchases from these sources used to be around 17 mu only. Extra purchases became possible as transmission lines were available for use for the time being connecting the State with upcountry grids. The overall unrestricted demand (with the usual cuts in rural areas) stood at 289 mu on Tuesday while the Transco could supply only 240 mu — a shortfall of 49 mu.

Adding to the woes, two units of NTPC’s pit-head super thermal station at Talcher in Orissa tripped due to coal shortage. As a result, AP lost 220 MW out of its share from there.

Even now, more than 90 per cent of the installed capacity available under the gas-based power stations in the State is kept idle for want of gas from D-6 well of K-G basin of Reliance Industries Limited.
