Objective, Norms and Methodology

4. Objective.

- The objectives of these regulations are to ensure compliance of the Standards of Performance by the inter-State transmission licensees and to provide for an efficient, reliable, coordinated and economical system of electricity transmission, non-adherence of which would entitle the affected parties to compensation.

5. Standards of Performance.

(1)All inter-State transmission licensees shall comply with the Standards of Performance specified in these regulations:-

(a)Transmission System Availability

(i)The transmission system availability shall be calculated element-wise on monthly basis, in the same manner as provided for in the Central Electricity Regulatory Commission (Terms and Conditions of Tariff) Regulations, 2009, as amended from time to time and any subsequent enactment thereof.

(ii)The deemed availability of the transmission elements under outage shall be as specified in the Central Electricity Regulatory Commission (Terms and Conditions of Tariff) Regulations, 2009, as amended from time to time and any subsequent enactment thereof.

(iii)The element-wise monthly availability of the transmission system shall not be below the availability as given below:-

SI. No.	Transmission Elements	Availability (% of time)
(i)	AC Transmission line	90
(ii)	ICTs	90
(iii)	Reactors	90
(iv)	Static VAR Compensator	90
(v)	Series Compensator	90
(vi)	HVDC (Back-to-back Stations and bi-pole links)	85

Notes : (1) Tower collapse shall not be counted for the purpose of calculation of monthly availability of AC transmission line and HVDC bipole line.

(2)Failure of Inter-Connecting Transformer (ICT) and Reactor shall not be counted for the purpose of calculation of availability of Inter-Connectivity Transformer and Reactor.

(iv)The element-wise monthly availability shall be certified by the Member-Secretary of the Regional Power Committee.

(b)Restoration time

Restoration time for different types of failures of transmission line and Inter-Connecting Transformer (ICT) and reactors shall not exceed the following time limit:-

SI. No.	Types of failures	Restoration Time (Days)
1.	Insulator failure

6.

Any failure by the inter-State transmission licensee to maintain the standards of performance specified in these regulations shall render the said licensee liable to payment of compensation to an affected person claiming such compensation under the provisions of the Act:Provided also that the payment of compensation by the Inter-State transmission licensee shall be without prejudice to any penalty, which may be imposed or any prosecution which may be initiated by the Commission as provided in the Act.

7. Methodology for compensation.

- An affected person who has suffered a loss on account of non-adherence to the Standard of Performance by any inter-State transmission licensee may make an appropriate application to the Commission for award of compensation:Provided that the Commission shall determine the compensation after giving reasonable opportunity to the transmission licensees of being heard:Provided Further that the compensation to be paid by the inter-State transmission licensee to the affected party shall be limited to the transmission charges of the particular element to the extent to which it has affected the supply of electricity to the affected person:Provided Further that the inter-State transmission licensee shall not be entitled to recover the amount of compensation awarded through tariff from the users of the transmission electricity:Provided also that no claim for compensation shall be entertained if the application for the claim is filed after expiry of a period of ninety days from the end of the month when the availability of the transmission system falls short of the availability specified in clause 5(a) and ninety days from the date of restoration of transmission element, as the case may be, for the standards prescribed in clause (b) of Regulation 5 of these regulations.

Chapter 3
Information to be Furnished by the Inter-State Transmission Licensees

8. Information to be furnished by the inter-State Transmission Licensees.

(1)All inter-State transmission licensees, in accordance with section 59 of the Act, shall furnish to the Commission, (a) the level of performance achieved; and (b) the number of cases in which compensation was paid; and (c) the aggregate amount of the compensation, in the formats in the Schedule of these regulations.
