- (1.)THE Central Electricity Regulatory Commission (Sharing of Inter -State Transmission Charges and Losses) Regulations, 2010 (hereinafter "Sharing Regulations") came into effect from 1.7.2011.
(2.)NATIONAL Load Dispatch Centre as the Implementing Agency has been entrusted with the responsibility for computation of transmission charges and losses under the Sharing Regulations for each financial year. Further, Regulation 17 of the Sharing Regulations provides that the Implementing Agency shall be required to provide the following information consequent to the computation of transmission charges and losses undertaken by it:
(a) Approved Basic Network Data and Assumptions, if any; (b) Zonal or nodal transmission charges for the next financial year differentiated by block of months; (c) Zonal or nodal transmission losses data; (d) Schedule of charges payable by each constituent for the future Application Period, after undertaking necessary true -up of costs as per these regulations and detailed procedures.

(3.)THE Implementing Agency in its letter No. POSOCO/Trans. Pricing/DICs dated 23.11.2012 has submitted following information in compliance with Regulation 17 of the Sharing Regulations:
(a) Basic Network and load flow data approved by Validation Committee (b) Yearly Transmission Charge (YTC) details of ISTS Licensees (c) PoC rates and loss percentage computation details (d) Assumptions used for computation of PoC rates and Losses (e) Schedule of charges payable by each DIC for the year 2012 -13 (period October 2012 to March, 2013) (f) List of assets of other non -ISTS Licensees whose assets have been certified as being used for interstate transmission by the RPCs (Whose transmission charges have been considered for sharing along with the ISTS)

We have carefully examined the basic network data and assumptions, the results of the Load Flow Studies, the yearly transmission charges of the ISTS licensees and the calculation of POC charges for generation and demand zone submitted by the Implementing Agency. It is noticed that the Implementing Agency has considered the zoning of the inter -State Generation Stations on the basis of the joint reading of Regulation 3(a) and Regulation 7(1)(t)(iv) of the Sharing Regulations, i.e. in order to be considered as a separate zone for the purpose of PoC rates, two parameters, namely generating station being considered as regional entity as per Grid Code and being directly connected to 400 kV ISTS, have been taken into account. We approve the proposed zoning of such generating stations as a generating station in order to be considered as a separate zone should not only be a regional entity having beneficiaries in more than one state and its scheduling being done by RLDC but should also be directly connected to the 400 kV ISTS. As a result of such zoning, generating station of Ratnagiri Gas and Power Limited and Indira Gandhi Super Thermal Power Project, Jhajjar which are regional entities but are connected to the ISTS through the state transmission systems of Maharashtra and Haryana respectively will now be considered according to the injection PoC rate of the concerned State. We have also examined the calculation of losses on POC basis, average losses, final % losses applicable on generation and demand zones. We find that the calculations submitted by the Implementing Agency have been done as per the Sharing Regulations and amendments thereof.
