Objective, Norms and Methodology
4. Objective. - The objectives of these regulations are to ensure compliance of the Standards of Performance by the intra-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 intra-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 manner as provided in the Bihar Electricity Regulatory Commission (Multi Year Transmission Tariff and SLDC Charges) Regulations, 2018, 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 Bihar Electricity Regulatory Commission (Multi Year Transmission Tariff and SLDC Charges) Regulations, 2018, 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 under:

Information to be Furnished by the Intra-State Transmission licensees
8. Information to be furnished by the intra-State Transmission Licensees. - (1) All intra- 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. (2) Such information in the requisite formats shall be submitted to the Commission twice during the financial year, on six monthly basis by 31st October and 30th April for the periods April to September and October to March respectively. (3) All intra-State transmission licensees shall display on their websites the actual performance against the specified Standards of Performance on a monthly basis and the aggregate amount of compensation paid, if any, in the formats enclosed in the Schedule.Chapter 4
Miscellaneous
9. Power to Relax. - The Commission may, if it considers necessary or expedient to do so and for the reasons to be recorded in writing, relax adherence to any specific Standard of Performance during Force Majeure conditions such as war, mutiny, civil commotion, riot, flood, cyclone, Storm, lightning, earthquake, grid failure, and strike/curfew, lockout, fire affecting the intra-State Transmission Licensee's installations and operation activities, or under such other specific circumstances: Provided that the Intra-State Transmission Licensee shall not be discharged from its liability on account of its failure to maintain the Standards of Performance under these regulations if such failure can be attributed to the negligence or deficiency or lack of preventive maintenance of the intra-state transmission system or failure to take reasonable precaution which has resulted in loss to the affected person. 10. Power to remove difficulties. - If any difficulty arises in giving effect to any of the provisions of these Regulations, the Commission may, by general or specific order, make such provisions not inconsistent with the provisions of the Act, as may appear to be necessary for removing the difficulty. 11. Power to Amend. - The commission may, at any time after consultation with the licensees and other persons likely to be affected add, vary, alter, modify or amend any provisions of these regulations.Schedule

IV. Data to be furnished by the intra-State Transmission Licensees to SLDC
(1) The Dependability Index defined as D=Nc/ (Nc+Nf)
Where Nc is the number of correct operations during the given time interval and Nf is the number of failures to operate at internal power system faults
(2) The Security Index defined as S= Nc/(Nc+Nu)
where Nu is the number of unwanted operations.
(3) The Reliability Index defined R= Nc/(Nc+Ni)
where Ni is the number of incorrect operations and is the sum of NF and Nu.
(4) From above 1/S+1/D= 1/R+1
(5) The number of trippings of each transmission element. Five or more trippings of a transmission element in a month to be put on the website by the intra-State Transmission Licensees and reported to the Commission by SLDC
Note. - 1. The data for these indices are presently prescribed for collection by the System Operator.
