The reliability of the transmission system is very high, almost 100 per cent, and that of
the distribution system is rated as 99 per cent. The Board has put in place a system for
measuring and monitoring interruptions, a major area of complaints from the public.
The distribution transformers (DTs) failure rate has been brought down from 10.99
per cent in 1998-99 to 7.3 per cent in 2004-05. The failure rate of power transformers
too was low, only 1.45 per cent in 2004-05. The Board meters all supplies except
agricultural supply, since it is free – agriculturists are getting free power from the
Board since 1990. The system of collection is excellent; services are disconnected if
the dues are not paid within a specified date, which results in almost 100 per cent
collection. The Board has been maintaining this system for decades, which has been
accepted by consumers without any resentment. The maintenance of the transmission
and distribution system can be rated as good based on the above facts.
FINANCIAL PERFORMANCE
As mentioned earlier, the financial position of the Board is seriously affected by free
power to the agricultural sector on Government directive and the highly subsidised
power to the domestic sector. Although the government is mandated to compensate
the Board for its losses, it has not been able to do so because of its own financial
difficulties. The situation has somewhat improved with the setting up the SERC, and
there is now a legal force for compensation.
This has naturally led to continued losses despite its good technical performance as
could be seen from the details given below:
