1 Renewable Regulatory Fund () Mechanism : -

2 : Chronology of events Outline : Objectives at a glance : Approach : Applicability Role of different stakeholders Brief on CERC Orders on State Load Dispatch Centre-GETCO 2

3 : Chronology of events IEGC Regulations, 2010 notified on Clause 5 and Clause 7 of Annexure 1 of IEGC : UI charges arrived at due to the variation of generation by wind and solar shall be shared amongst all the states through Renewable Regulatory Charge to be operated through Renewable Regulatory Fund. Clause 9 of Annexure 1 of IEGC : NLDC shall prepare a detailed procedure for implementation of the mechanism of Renewable Regulatory Fund and submit the same for approval by the Commission. CERC examined the proposal submitted by NLDC and the modified procedure was notified on State Load Dispatch Centre-GETCO 3

4 : Objectives at a glance Scheduling of Wind/Solar generation Generation from renewable to become more acceptable and market friendly States already having met RPO targets may not find it averse to encourage renewable generation further Better System Operation State Load Dispatch Centre-GETCO 4

5 : Approach Achieve better generation prediction using weather forecasting tools Immune wind generators from paying deviation in UI charges up to a certain level of variation No UI charges payable/receivable by Solar Generator Socialize the deviation charges arrived due to variations amongst different state utilities Develop a self sustaining mechanism towards better acceptance of intermittent generation State Load Dispatch Centre-GETCO 5

6 : Applicability Commissioning of pooling stations on or after Pooling station shall be considered as a basic building block for the purpose of scheduling, metering & energy accounting Wind Generators/Coordina ting Agency shall be responsible for the purpose of scheduling, metering & energy accounting Wind farm with Collective Cap. of 10 MW and above, Solar with cap. of 5 MW and above & plant connection Point 33 KV & Above Applicability Not Applicable to plants selling power through Collective Transactions State Load Dispatch Centre-GETCO 6

7 Role of different stakeholders towards Implementation State Load Dispatch Centre-GETCO 7

8 Role of Wind Generators Wind farms 10 MW and above, connected at 33 KV and above and commissioned their pooling station on or after Submission of connectivity details to concerned SLDC/RLDC Declaration about agreement, if any Provide details of Contracts and Contracted path to the concerned SLDC RLDC RPC Generation forecast with periodic updates to SLDC RLDC To provide Data Acquisition System facility to SLDC. State Load Dispatch Centre-GETCO 8

9 SLDCs Role of SLDCs/RPCs/RLDCs/NLDC (1)» Scheduling on daily basis with periodic revisions» Schedule and actual generation meter data to be sent to RLDCs and RPCs» Payments/receipts to/from concerned Generators and Settlement of accounts with RLDCs» Processed data of energy meters along with final schedule to be sent to RPCs on weekly basis» Vetting of solar generation schedule & Monitoring and performing checks» Direct co-ordination with Regional entities for contracts & energy meter data State Load Dispatch Centre-GETCO 9

10 Role of SLDCs/RPCs/RLDCs/NLDC (2) RPCs» Issuance of Statement of Energy Accounting on Weekly basis» Data handling of contracts for issuance of energy and deviation accounts» To work out details towards Capping, Additional UI charges etc. if any. NLDC» To maintain and operate» Issuance of statement & collection of Renewable Regulatory Charge State Load Dispatch Centre-GETCO 10

12 CERC Hearings and Orders Suo - motu Petition of CERC dated and subsequent hearings on , , and on As directed in hearing in CERC on , MNRE has convened a meeting on As per OM dated , MNRE has constituted the task force under Mr. S. K. Soonee, CEO POSOCO to resolve the implementation issues As per CERC Order dated , report of the task force along with suggested measures to be submitted to the commission by CERC Has issued final order on State Load Dispatch Centre-GETCO 12

13 Brief of Final Order A. Point of scheduling, coordination agency and eligible generators: Pooling station considered as basic building block. Concept of coordinating agency introduced. Any person, generator or any other mutually agreed agency. The pooling stations that are commissioned on or after have been considered for the purpose of mechanism. Necessary amendment in IEGC is in process. State Load Dispatch Centre-GETCO 13

14 Brief of Final Order B. Payment mechanism Existing method for payment of energy charges as per actual generation is to be continued. State Load Dispatch Centre-GETCO 14

15 Brief of Final Order C. Multiple contract rates, captive wind generating plants, other options Concept of reference rate is introduced. Reference rate for New Grid: Rs.4.00 Reference rate for SR Grid: Rs.5.00 For wheeling, Contract rate would be: ZERO Reference rate is for determining financial implication for variability of wind generator, irrespective of whether it is selling to the state through a contract or through open access. Financial implication would be the difference between Reference Rate and UI rate. State Load Dispatch Centre-GETCO 15

16 Brief of Final Order D. De-pooling Arrangement. Preferably mutually agreed mechanism. In case of disagreement, the UI charges should be shared based on actual generation on weekly basis during the same time frame. State Load Dispatch Centre-GETCO 16

17 Brief of Final Order E. Over generation above 50% of schedule. UI cap rate for over generation above 50% of the schedule shall be continued. State Load Dispatch Centre-GETCO 17

18 Brief of Final Order F. Miscellaneous Metering, Data acquisition and data communication shall be as per prevailing norms of Grid code. In case the ABT meter is not installed by the respective STU or DISCOM by , the same may be installed by CTU at the cost of concerned STU/DISCOM. Mock exercise for forecasting and scheduling has already been commenced from NLDC is directed to align the procedure for implementation of the mechanism of which is under process. State Load Dispatch Centre-GETCO 18

19 Scheduling and Settlement of Accounts (As per old procedure) Scheduling of Wind power generation plant is being carried out under mock trial and it will be implemented with full commercial impact from The schedule by wind power generating stations may be revised by giving advance notice to SLDC. The revision by wind power generating station will be effective from 6 th time-block. There may be maximum of 8 revisions for each 3 hour time slot starting form 00:00 hours during the day. Concerned RLDC/SLDC shall maintain the record of schedule from renewable power generating station based on type of renewable energy source. State Load Dispatch Centre-GETCO 19

20 Contd.. Wind Generators shall be responsible for forecasting their generation up to an accuracy of 70%. Actual Generation beyond +/- 30% of schedule, UI charges would be applicable. Actual Generation within +/- 30%, no UI charges to Generator. Variation within +/- 30%, UI would be applicable to host State. UI charges shall be shared among all the States of the country in the ratio of their peak demand met in the previous month. Max. generation of 150% of schedule would be allowed in a time block, from grid security point of view. Generation above 150%, charges payable to WEG would be UI charges corresponding to Hz. For intra-state transactions, deviation of actual generation within +/-30% would be settled through. Deviation outside +/-30% would be settled directly. State Load Dispatch Centre-GETCO 20

21 Contd.. For inter-state transactions, deviation of actual generation for the purchasing State would be settled at UI rate through. Implication due to deviation within +/-30% would be settled with host State through. Deviation outside +/-30% would be settled directly. If sale of power to two or more States, the deviation would be dealt with proportionate to the share in the generation of wind farm. Host State will receive compensation from, for total or part difference of schedule and actual generation additional UI rate on account of under-generation by WEG as per the CERC UI regulation Host State also will receive from, difference between UI rate and cap UI rate for under drawl beyond the % MW prescribed in UI regulation, to the extent of Under drawl by State because of over generation by WEG.
