COMMENTS
The general power supply position in Rajasthan is satisfactory. Supply during peak
load hours has substantially increased from 2,728 MW in 1995-96 to 4,267 MW in
2003-04. But along with this, demand is also increasing at a much faster pace. As a
result, the peak shortage, which used to be in the range of 21 to 23 per cent earlier, is
now ranging between 26 to 30 per cent. Due to ever increasing demand of the
agricultural sector, frequent power cuts have been imposed on industries causing
heavy losses to them. The energy shortage is marginal. This is ranging around three
per cent, which is a slight improvement over the previous years.
The earlier failure rate of transformers is not readily available but in the postrestructuring
period the failure rate of distribution transformers has increased from
13.43 to 17.55 per cent. In the case of power transformers, the failure rate has come
down from 14.96 to 11.13 per cent.
