Vijayawada- The heavy inflows into Srisailam dam across river Krishna has come as a boon to the Andhra Pradesh government. The flood discharge in Srisailam will help boost hydel power generation bringing in cheap power into the state electricity grid.
About 715 million units of hydel power is expected to be generated from Srisailam powerhouses at a cost of Rs 1,14.4 crore or Rs 1.6 per unit. On the other hand, the generation cost of thermal power for the same quantity is Rs 329 crore or Rs 4.6 per unit. The government expects to save Rs 215 crore in the power sector this monsoon. This will provide relief to discoms, which have been unable to buy power at exorbitant rates, according to official sources.
This was revealed at a teleconference held by energy, forest and environment minister Balineni Srinivasa Reddy on Sunday with energy department officials on the impact of massive inflows into Srisailam dam and generation of hydel power.
At the conference, energy secretary N Srikant said according to recent estimates generation of hydel power was recorded at 24 million units from all reservoirs against 20 MU during the same period in 2018. Discoms will prepare a revised action plan to meet peak demand in the kharif season, expected to reach 185 MU per day.
AP Genco managing director B Sreedhar said while Srisailam powerhouse can generate 16.5 MU per day, the Nagarjunasagar tail pond (50 MW) has started generating power of one million units per day. Officials hope to generate three MU per day through Nagarjunasagar right canal power house (90 MW) within a few days.
Srinivasa Reddy added that the massive inflows into Srisailam would boost hydel power generation. “It is the first time in several years that water was released from Srisailam to Nagarjunasagar project in the second week of August and hydel power generation began at right bank power house. It is expected to generate 715 MU of power this year from Srisailam. This would be the highest in recent years. Hydel power generation may also start from Nagarjunasagar soon,” he said.
The overall power demand was recorded as 162 MU on Sunday against the demand of 148 MU during the first week of August. The power demand had touched the highest 200 MU in May and 181 MU in July second week this year. Following good rains, the demand has come down to 30 MU per day in the first week of this month. This helped the power utilities to save about Rs 100 crore. The demand may reach 185 MU during kharif season.
Srisailam right bank power house can generate 165 million units for the next 10 days at the rate of 16.5 MU a day. If the Krishna river management board (KRMB) allocates 100 tmc ft of water to Andhra Pradesh, Genco would generate around 550 MU of hydel power, he said.
