Low storage in reservoirs may affect hydro power output

Thermal plants undergo trials, ready to step in for hydel units

With the state’s hydel power output expected to dip due to low reservoir levels, the energy department is conducting trials on thermal plants to generate 2,300 MW from October onwards.

Trial runs to supply 1,600 MW from two units of Yeramarus Thermal Power Station (YTPS) and 700 MW from Bellary Thermal Power Station (BTPS) third unit have begun.

If this succeeds, then supply of an additional 2,300 MW to the grid will start in October, G Kumar Naik, managing director of Karnataka Power Corporation Ltd, told DH.

Trials to generate 700 MW power from BTPS began last week and on Friday (Aug 19), 480 MW power was generated.

From August-end, generation of 800 MW from the first unit of YTPS will start.

Subsequently, generation of another 800 MW from YTPS' second unit will commence.

Naik added that since one third of the power (state’s requirement) is generated from hydel sources, the state may fall short of the requirement if rains fail.

The present generation is helping meet the peak load and will suffice till February.

Things can worsen from March. “Since the flexibility has been lost, other plans are being chalked and trial runs to add more power to the grid have started,” Naik said.
Jawaid Akhtar, managing director, Karnataka Power Transmission Corporation Ltd, said that presently, the state is managing with its own generation and all discussions are being held  for the future. Presently, the demand and supply gap is being met. The peak demand on Thursday (August 19, 2016) was 8,789 MW.

The average storage in three major dams is only 48% of their full level. Lingamanakki is 49.52% full, Supa 47.88% and Mani is just 48.57% of its full capacity. The present power generation capacity is 4,242 MW against 4,036 MW last year.

No power is being purchased presently. All the power purchase agreements have expired in May, 2016.

However, the state has been getting 3,921 MW of power a day from the central grid
under a long-term arrangement.

The other major source of power is UPCL, from where a maximum capacity of 1,200 MW can be obtained. On Thursday, the plant supplied 536 MW, Akhtar added.
