Notably, farmers are provided free power by the government. The state government has pegged the subsidy burden on account of free power at Rs 6,000 crore for 2017-18.

The fixed charges will be in the range of Rs 20 per kW to Rs 60 kVA for domestic supply, Rs 50 to 100 per kVA for commercial supply and Rs 85 to 295 per kVA for industrial category including bulk supply, as per the order.
Addressing media persons here, Sidhu said the consolidated gap of Punjab State Power Corporation Limited was worked out at Rs 2,522.62 crore against power utility's proposal of Rs 11,575.53 crore.
"This new tariff is fixed for one year 2017-18," said the chairperson.
However, expenditure of three years has been finalized and annual revenue requirement (ARR) has also been fixed but not tariff for next two years, she added.
The net revenue requirement for PSPCL has been worked out at Rs 28,910.35 crore, Rs 30,241.30 crore and Rs 31,739.58 crore for 2017-18, 2018-19 and 2019-20 respectively.
The two part tariff structure envisages a fixed charge and a variable charge which has been adopted by almost all the states in line with national tariff policy, she said.
The power subsidy burden for the year 2017-18 has been estimated at Rs 10,970 crore including free power to farmers, subsidized power to SC/BC and arrears of Rs 2,800 crore.
However, the subsidy burden does not include the subsidised power at the rate of Rs 5 per unit to industrial category which has been announced by Congress led government in Punjab.

AAP MLA and leader of opposition in Punjab assembly Sukhpal Khaira while condemned the hike in power tariff said it will further dd to the woes of common people who are already facing "steep" inflation. "We demand its rollback," he said.
