The spread of high voltage transmission lines (≥ 11 kV) is such that it can form a square matrix of area 1.93 km² (i.e. on average, at least one HT line within 0.7 km vicinity) in 160,205 km² total area of the state. DISCOMs owned and operated LT lines (below 11 kV) are 292,158 circuit kilometres. Therefore, there are at least one HT or LT line availability on average within the vicinity of 306 meters in the entire state. However, to 31 July 2015, the maximum peak load met was only 6847 MW, and the annual energy supplied was 48,323 million kWh during the year 2014-15.
