According to the state Chief Minister Mr N Chandrababu Naidu, the reason for the power cut is failure of the the central sector units to supply committed power to the tune of 11 million units including Neyveli unit of 6.6 million units.
Further, poor rainfall at the Krishna basin has aggravated the power situation. Though the power generation is expected to be 2470 MW from the Krishna basis - Srisailam Right Bank 770 MW, Srisailam Light Bank 800 MW and Nagarjunasagar 900 MW - due to lack of water in the reservoirs the power generation has almost come to standstill.
While the present demand per day is estimated at 145.5 million units, the generation is just at 137.5 million units leaving a demand-supply gap of just 8 million units per day. It is attributed to the lower generation of power at the hydel units besides shutdown of some of the central sector genration units in the state.
According to the APTransco sources, the corporation has stopped the power supply to Tamil Nadu and Karnataka. As per the earlier agreements with both the states, Andhra Pradesh is expected to supply 3.5 million units.
Mr Naidu claimed that Andhra Pradesh has added about 4,216 MW capacity in the last 3 to 4 years and proposed to further increase the capacity by another 3,300 MW in the next 3 to 4 years.
Meanwhile, APTransco has asked the private gas power units including AP Genco units to postpone their plan to shutdown for annual maintenance and repairs, as a standby support to power grid. Further it asked the NTPC Simhadri unit to maintain the power generation even from the second 500 MW unit.
Speaking on the drought situation in the state, Mr Naidu said that the drinking water problem is alrming and Hyderabad and Visakhapatnam may also have to suffer with water supply restrictions. "We have asked railways to extend rakes for transportation of water and fodder", he said.
Further, Mr Naidu renewed his appeal to Karnataka to release water from the Almatti dam as they are not using the water as of now.
