2. Audit of SR UI & Reactive accounts Reconciliation statement sent on 27.10.2010 Response received from NLC stg I &II,NLC I Expn, TNEB,KPTCL,KSEB Reconciliation statement for Oct 10 also sent on 16.11.10statement

3. Scheduling of Talcher stg II Clause 6.4 of IEGC The national interconnected grid is divided into control areas, like Regional ISTS, States, DVC, etc. where the load dispatch centre or system operator of the respective control area controls its generation and/or load to maintain its interchange schedule with other control areas whenever required to do so and contributes to frequency regulation of the synchronously operating system. The Load Despatch Centre of a control area therefore is responsible for coordinating the scheduling of a generating station, within the control area, real time monitoring the station’s operation, checking that there is no gaming (gaming is an intentional mis-declaration of a parameter related to commercial mechanism in vogue, in order to make an undue commercial gain) in its availability declaration or in any other way revision of availability declaration and injection schedule, switching instructions, metering and energy accounting, issuance of UI accounts within the control area, collections/disbursement of UI payments, outageplaning etc.. Control area definition in IEGC: An electrical system bounded by interconnections (tie lines), metering and telemetry which controls its generation and/or load to maintain its interchange schedule with other control areas whenever required to do so and contributes to frequency regulation of the synchronously operating system.

4. Why SRLDC ? Minimal to and fro co-ordination between RLDC’s and SLDc’s in case of scheduling process involving surrender,recall etc. Less time in to and fro communication Right from planning to implementation Talcher II is apart of SR system. Only geographically located in ER system SR boundary is upto Talcher AC I/C & Jeypore end of Gazuwaka line In analogy to 6.4.2c(iii) of IEGC and SoR of IEGC 2010 in para 41.13, the control area jurisdiction of Talcher-II shall be with SRLDC as more than 50% share is to SR constituents.SoR of IEGC 2010 In case of Open Access transaction also the nodal RLDC is that of importing region. On same Anology SRLDC is nodal agency for Talcher-II

5. It plays a vital role in the LGBR of SR SPS already in place for eventualities like unit /pole tripping. Present system is working fine for over 8 years. Continued

6. Extracts from SoR on IEGC dt.18.06.2010 41. Demarcation of responsibilities( Regulation 6.4 of draft grid code regulations) 41.13 This has been done to ensure certainty in the demarcation of responsibilities. The IPP with their business strategy would decide quantum of power to be sold through long term, Medium term and short terms. The connectivity to ISTS and STU system indicates that generator wants to avail this flexibility. As the customer of this type of generator would be in more than one region, RLDC through its communication system would be able to coordinate with more than one regions and also RLDC would be aware of system operating conditions like transmission constraints, Voltage conditions etc and would be in better position to ensure that scheduling to various consumers of the IPP is done optimally on day to day basis. Hence, we have decided that if the host State has more than 50% share of power, then that generating station shall be under the jurisdiction of SLDC, else it shall be under RLDC. Regarding the apprehension of some stakeholders on frequent toggling of control area jurisdiction, it is clarified that the control area jurisdiction is decided on the basis of permanent share of the host State, which will not change frequently, hence frequent toggling would not be there. Moreover, initially when one or two units/ stages of the project will come under commercial operation, the jurisdiction would be more likely with SLDC depending on the share of the host State. On the progressive commissioning of units/ stages, it is more likely that the share of the host State would decrease and become equal to or less than 50%, resulting in shifting of control area jurisdiction from SLDC to RLDC. In future also, when more units are commissioned, it is more likely that the control area jurisdiction will remain with RLDC and there would not be frequent toggling. Regarding the apprehension of some stakeholders about the problem in metering during due to this toggling, it is clarified that the interface meters at CTU and STU interfaces shall be installed as per the CEA regulations on metering. It is further clarified that as switchover of control area would be done expeditiously after the change w.e.f. the next billing period i.e. next week UI accounting there shall not be any problem in energy accounting as anticipated by SLDC, Maharashtra. For inter-State energy accounting, it shall be as per CERC ABT mechanism.

7. SEM STATUS Installation of standby SEMs for NLC feeders: As decided in the Special Committee meeting at Neyveli, SEMs are to be installed by NLC and TNEB at the remote end of 220kV feeders emanating from TS-II stage I. Its more than 6 months but the SEMs are yet to be installed. The status may please be intimated.
