The approved tariff determined by the Commission is binding on the licensee and consumers, and no one else has the authority to alter or vary the approved tariff.

( 1 ) THIS writ petition under Art. 226 of the Constitution has been filed for quashing of the 15 per cent surcharge levied on the energy charge in the electricity bill of the petitioner for August, 2000.

( 2 ) THE petitioner is a company registered under the provisions of Companies Act and is engaged in manufacturing two wheelers (scooters and motor cycles ). The petitioner entered into an agreement with U. P. State Electricity Board (hereinafter referred to as UPSEB) on 31-10-1996 for supply of electrical energy in the form of a three phase alternative current at declared pressure of 132 KV and a power not exceeding 800 KV to its factory at A-1, Panki Industrial Area, Site III, Kanpur. The petitioner claims that it is running a non-continuous process industry and has to observe peak hour restirction and, consequently, it does not consume power from 6. 00 p. m. to 11-00 pm. A new tariff was enforced with effect from 9-8-2000 and in the bill dated 5-9-2000 a surcharge of Rs. 6,33,898. 45 was levied on total energy charge of Rs. 42,25,989. 68. The petitioner contends that as it is observing peak hour restriction and is not consuming power during the restricted hours i. e. from 6. 00 pm. to 11. 00 p. m. the levy of surcharge @ 15 per cent is illegal as the same can be levied only on a consumer who is not observing peak hour restriction. The plea taken in the counter affidavit filed by Kanpur Electric Supply Company (herein after referred to as KESCO) is that power is being supplied to the petitioner by an independent feeder emanating from 132 K. V. Navbasta Sub-station and, consequently, under the tarrif approved by U. P. Electricity Regulatory Commission, the petitioner is liable to pay 15 per cent surcharge on energy charge. It further pleaded that this 15 per cent surcharge is not dependent upon observance of peak hour restriction and those who do not observe this restriction and consume power between 6 pm. and 11 pm. have to pay an additional amount of 15 per cent surcharge on energy charge.
