Regulations for access to inter-state transmission system The transmission customers shall be divided into two categories, namely: - (a) Long-term customers, and (b) Short-term customers. The persons availing or intending to avail access to the inter-state transmission system for a period of twenty five years or more shall be the long term customers, The maximum duration for which the short-term access allowed at a time shall not exceed one year.
The transmission charges for use of the transmission system of the transmission licensee for inter-state transmission shall be regulated as under:- • The annual transmission charges payable by a long-term customer for use of the transmission system shall be determined in accordance with the terms and conditions of tariff notified by the Appropriate Commission from time to time and after deducting the adjustable revenue received from the short-term customers, these charges shall be shared by the long-term customers. (ii) The transmission charges payable by a short-term customer shall be calculated in accordance with the following methodology, namely:- (a) Intra-regional system ST_RATE = 0.25 x [TSC/ Av_CAP]/ 365 (b) Inter-regional system ST_RATE = 0.50 [ TSC/ CIR]/365 Where: ST_RATE is the rate for short-term customer in Rs per MW per day. Note:- ST_RATE shall be calculated and applied for each regional transmission system, inter-regional transmission link, and transmission system of the State Transmission Utility or any other transmission licensee forming part of the inter-state transmission system. "TSC" means the annual transmission charges. "Av_CAP" means the average capacity in MW served by the intraregional transmission system of the transmission licensee in the previous financial year ( sum of the generating capacities connected to the transmission system and contracted capacities of other long-term transactions handled by the system of the transmission Licensee) “CIR” means the transmission capacity of the inter-regional system
The transmission charges payable by a short-term customer in case of uncongested transmission corridor shall be levied as under, namely :- (a) Up to 6 hours in a day in one block : 1/4th of ST_RATE (b) More than 6 hours and up to 12 hours in a day in one block : 1/2 of ST_RATE (c) More than 12 hours and upto 24 hours in a day in one block : equal to ST _ RATE
Every transmission licensee shall declare ST _ RATE, calculated in accordance with clause (ii) above, which shall remain fixed for a period of one year. (vi) If the transmission system belongs to the Central Transmission Utility or State Transmission Utility, 25% of the charges collected from the short-term customer for use of its intra-regional transmission system and 12.5% of the charges collected from the short-term customers for use of its inter-regional system shall be retained by the Central Transmission Utility or State Transmission Utility and the remaining part of these charges shall be adjusted towards reduction in the transmission charges payable by the long-term customers. (vii) Open access charges specified in this regulation shall not be applicable for the inter-state transmission system in North-Eastern Region. The charges for use of the inter-state transmission in this region shall be regulated under the separate orders of the Commission issued from time to time.]
Operating Charge 17. (i) A composite operating charge @ Rs.3,000/- per day or part of the day and @ Rs 1,000/- per day or part of the day shall be payable by a short-term customer for each transaction to the each of the Regional Load Despatch Centre involved and State Load Despatch Centre respectively.
Unscheduled Inter-change (UI) charges 18. (i) The mismatch between the scheduled and the actual drawal at drawal point(s) and scheduled and the actual injection at injection point(s) shall be met from the grid and shall be governed by UI pricing mechanism applicable to the inter-state transactions; (ii) A separate bill for UI charges shall be issued to the direct customers and in case of the embedded customers, a composite UI bill for the State as a whole shall be issued, the segregation for which shall be done at the State level.
Legal provision for Tariff determination 61. The Appropriate Commission shall, subject to the provisions of this Act, specify the terms and conditions for the determination of tariff, and in doing so, shall be guided by the following, namely:- (a) the principles and methodologies specified by the Central Commission for determination of the tariff applicable to generating companies and transmission licensees; (b) the generation, transmission, distribution and supply of electricity are conducted on commercial principles; (c) the factors which would encourage competition, efficiency, economical use of the resources, good performance and optimum investments; (d) safeguarding of consumers' interestand at the same time, recovery of the cost of electricity in a reasonable manner; (e) the principles rewarding efficiency in performance; multi year tariffprinciples; (g) that the tariff progressively reflects the cost of supply of electricity and also, reduces and eliminates cross-subsidieswithin the period to be specified by the Appropriate Commission; (h) the promotion of co-generation and generation of electricity from renewable sourcesof energy; (i) the National Electricity Policy and tariff policy: Provided that the terms and conditions for determination of tariff under the Electricity (Supply) Act, 1948, the Electricity Regulatory Commission Act, 1998 and the enactments specified in the Schedule as they stood immediately before the appointed date, shall continue to apply for a period of one year or until the terms and conditions for tariff are specified under this section, whichever is earlier.
(1)The Appropriate Commission shall determine the tariff in accordance with provisions of this Act for – (a) supply of electricity by a generating company to a distribution licensee: Provided that the Appropriate Commission may, in case of shortage of supply of electricity, fix the minimum and maximum ceiling of tariff for sale or purchase of electricity in pursuance of an agreement, entered into between a generating company and a licensee or between licensees, for a period not exceeding one year to ensure reasonable prices of electricity; (b) transmission of electricity ; (c) wheeling of electricity; (d) retail sale of electricity. Provided that in case of distribution of electricity in the same area by two or more distribution licensees, the Appropriate Commission may, for promoting competition among distribution licensees, fix only maximum ceiling of tariff for retail sale of electricity. (2) The Appropriate Commission may require a licensee or a generating company to furnish separate details, as may be specified in respect of generation, transmission and distribution for determination of tariff. (3)The Appropriate Commission shall not, while determining the tariff under this Act, show undue preference to any consumer of electricity but may differentiate according to the consumer's load factor, power factor, voltage, total consumption of electricity during any specified period or the time at which the supply is required or the geographical position of any area, the nature of supply and the purpose for which the supply is required.
No tariff or part of any tariff may ordinarily be amended more frequently than once in any financial year, except in respect of any changes expressly permitted under the terms of any fuel surcharge formula as may be specified. (5) The Commission may require a licensee or a generating company to comply with such procedures as may be specified for calculating the expected revenues from the tariff and charges which he or it is permitted to recover. (6) If any licensee or a generating company recovers a price or charge exceeding the tariff determined under this section, the excess amount shall be recoverable by the person who has paid such price or charge along with interest equivalent to the bank rate without prejudice to any other liability incurred by the licensee.
