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/CERC dated 1.1.2015 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 fourth quarter of the year 2014–15 (period January to March, 2015)

(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)

4. We have 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. 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 Sharing Regulations and amendments thereof.

5. The Commission had by its order dated 26.12.2014 approved the slabs of PoC rates for National grid and also approved the slabs in respect of transmission losses. The Implementing Agency after computation of PoC rates and transmission losses for each injection and withdrawal zone has assigned them to different tiers of slabs. We have gone through the details furnished by Implementing Agency and find the same to be in order. We approve the applicable PoC slab rates for Long Term Access and Medium Term Open Access (MTOA) in Rs./MW/Month and rates for Short Term Open Access (STOA) in paisa per unit for each Generation (injection) zone and Demand (withdrawal) zone as per the details at Annexure-I to this order.

6. In the Principal Regulations it is provided that there shall be three slab rates for injection and demand PoC charges for the year up to 2013–14, after which the same shall be rationalized in the year 2014–15 based on a review by the Commission. The review of the slab rate as proposed in the third amendment of Sharing Regulations is under consideration of the Commission. The outcome of review will be applicable from the date as per decision of the Commission

7. Similarly, we have examined the details of PoC losses in percentage for each Generation (injection) zone and Demand (withdrawal) zone and its applicable slab as per slabs approved by the Commission and have found them to be in order. We, therefore, approve the same as per the details at Annexure—II to this order. These average slabs for each region shall be applied based on last week's actual Regional Losses.

8. In exercise of power under Regulation 17(2) of Sharing Regulations, we approve the Basic Network, Load Flow, assumptions used for computation of the final PoC rates and final transmission losses, their fitment into slabs and schedule of charges payable by each DIC for the Fourth quarter of the year 2014–15 i.e. from 1.1.2015 to 31.3.2015, as submitted by Implementing Agency. We also direct the Implementing Agency to publish zonal PoC Rates and zonal Transmission Losses and associated details that will enable a clear understanding of the calculations used for arriving at these rates, along with underlying network information and base load flows used, in accordance with the Regulation 17(3) of Sharing Regulations.

9. In order to ensure smooth change over for short term transactions from the existing rates to the new rates of sharing of transmission charges, we direct that in respect of the applications made for scheduling of bilateral and collective transactions received before 5.1.2015, short-term open access charges would be payable at the rates applicable for the application period from October-December, 2014(Q3) 2014–15 and for applications received on or after 5.1.2015 the short-term open access charges shall be payable as per the application period from 1.1.2015 to 31.3.2015 (Q4) 2014–15. In keeping with the application of weekly losses, we direct that the application of the new PoC loss slabs for Fourth quarter would be made applicable from 5.1.2015.

10. The Implementing Agency is directed to endorse a copy of this order to all DICs and other concerned agencies. The Implementing Agency and Central Transmission Utility shall also give wide publicity to this order through their websites.
