India will have a power surplus of 3.1% during peak hours and 1.1% during non-peak hours during 2016-'17, the report added. The peak-hour deficit was at -3.2% last year, while non-peak-hour deficit was at -2.1%. The deficit was as high as 13% about 10 years ago.
According to the data, the country will have more electricity than required from June. Half the states will have surplus power, while others may have a deficit in varying proportions. Southern and western India will have a surplus of 3.3% and 6.9%, respectively, and the eastern, north-eastern and northern regions will have a deficit of 10.3%, 8.3% and 1.8%, respectively. However, the data does not take into account that state utilities often choose to black out areas to reduce their losses, or because of a technical failure, the report said.
The government's data comes days after a joint study by the Associated Chambers of Commerce and Industry of India and consultancy firm PricewaterhouseCoopers concluded that India's power deficit may rise from 2.6% of peak demand in 2015-'16 to 5.6% in 2021-'22.
