3 Milestones towards One Country-One Grid - One Frequency 44 GW of Inter Regional Transfer 29 of kV 3 HVDC Back to Back stations National Load Dispatch Centre 3 Regional Load Dispatch Centre National Transmission Asset Management Centre (under commissioning) Worlds largest Wide Area Monitoring Project (under execution) Grid in st Dec 13 One Country One Grid One Frequency North West East Northeast Central Grid South Grid World s Largest Syncronised Grid 259 GW Dec. 14 South Till Regional Grids 5 Frequencies Presentation title - 18/03/2015 P 3 October 1991 East & Northeast synchronized March 2003 West synchronized with East & Northeast August 2006 North synchronized With Central Grid

4 Building India s Transmission Grid EHV/UHV AC backbone for increasing Power Flow - 29 out of kv AC have Alstom Grid technology Establishing India s Power 765 kv Established India s first 765 kv project at NTPC Sipat Maximum 765kV AC (EHV) substation orders awarded to Alstom Grid 29 out of 50 substations to have Alstom Products India s first local manufacture of 765 kv power transformer India s first local manufacture of GIS up to 400 kv India s first local manufacture of 1200 kv CVT for Power Grid Bina testing station 765 kv substations built India s first 765 kv SS at NTPC Sipat India s first locally manufactured 400 kv GIS India s first locally manufactured 1200 kv CVT for Power Grid Note: EHV - Extra High Voltage (765 kv) UHV - Ultra High Voltage (1200 kv) Presentation title - 18/03/2015 P 4

5 Building India s Transmission Grid 800 kv HVDC links for increasing Power Flow & Reactive Power Control - 3 Back to Back HVDC built by Alstom Grid - 2 Large HVDC each of 800 kv / 3000 MW under execution 800 kv/3,000 MW HVDC Champa-Kurushetra Sasaram, India: 500 MW interconnection of the Eastern and Northern networks HVDC Projects In India Pioneer in Inter-Regional Power bulk power transfer by building 3 Back-to-Back HVDC projects In addition to the transmission of real power between the regions, the links provided also perform a reactive power control role, which helps to stabilize the network voltage. 2,000 MW Voltage level: 500 kv Chandrapur: 1000 MW interconnection between the Western and Southern networks Visakhapatnam: 500 MW interconnection between the Eastern & Southern networks HVDC Convertor Station at Sasaram HVDC Thyristors at Chandrapur HVDC links by Alstom Grid Presentation title - 18/03/2015 P 5

6 70% of India s Transmission Grid Power flow is managed by Alstom Grid technology Strong Leadership in Network Management System in India NLDC NRLDC WRLDC NLDC Bhutan NERLDC NLDC Bangladesh ERLDC Bkup NLDC 3 out of 5 Regional Load Dispatch Centre 4 out of 4 National Load Dispatch Centers in India, Bangladesh, Bhutan and Sri Lanka (under execution). National Load dispatch center for India handles 136 GW of power flow. Load Dispatch Centers at Bangladesh and Bhutan handle 100 % of power flow in the respective countries. NTAMC, world s largest Remote Asset Management project (under commissioning) URTDSM, World s largest wide area monitoring project (under execution) SRLDC NLDC Sri Lanka Presentation title - 18/03/2015 P 6 National Load Dispatch Center (NLDC) by AG Backup National Load Dispatch Center (BNLDC) by AG Regional Load Dispatch Centers (RLDC) by AG Regional Load Dispatch Centers by 3 rd party NLDC, India NLDC, Bhutan NLDC, Bangladesh

7 NTAMC (Under Commissioning) National Transmission Asset Management Centre Integrated World s Largest Transmission Asset Management System Involving 192 Grid Substations NLDC NRLDC WRLDC NTAMC NLDC Bhutan NERLDC NLDC Bangladesh ERLDC Bkup NLDC By Implementing NTAMC & ULDC, Power Grid has segregated the Operation & Asset Management functions with a common set of field measurement devices Access Control, Visual Monitoring, Video Conferencing, IP Telephony integrated into system Objectives met by NTAMC: Enable unmanned remote maintenance operation of transmission assets Redeploy & optimise skilled resources at maintenance hubs & reduce administrative costs Remote fault finding/analysis - reduced down time SRLDC Bkup NTAMC NLDC Sri Lanka NTAMC by AG Backup NTAMC by AG RTAMC by AG Presentation title - 18/03/2015 P 7 National Load Dispatch Center (NLDC) by AG Backup National Load Dispatch Center (BNLDC) by AG Regional Load Dispatch Centers (RLDC) by AG Regional Load Dispatch Centers by 3 rd party

8 URTDSM (Under Execution) World s Largest Wide Area Monitoring Project Super PDC at NLDC Super PDC at Bkup NLDC Project to integrate ~1400 PMUs to the Grid Control Centres To enhance Grid Stability thru closer monitoring of Phasor Angle differences and the state of damping of low signal oscillations Maximise Power Flow OFC Cloud PMUs located at State Sector Substations Presentation title - 18/03/2015 P 8 PMUs located at IPPs PMUs located at Power Grid S/S, Central Sector S/S PMUs located at State Sector Sector Substations

9 Benefits Power Grid India s Technology Road Map Power Grid can leverage Alstom Grid s local world class manufacturing facilities of both EHV & UHV AC-DC Technologies for bulk power transport across India s five electrical regions which is expected to reach ~66 GW by This industrialisation to help Power Grid, Manage the largest synchronised grid in the world (installed capacity of 259 GW) Deal with Power transport between India and neighbouring countries in India Region To manage significant increase of Grid Interactive renewable power generation, from 13% (33.8 GW) today to 21% by 2022 Digital Substation technology for AIS & GIS have demonstrated a paradigm shift in, Reduction in copper use and size of bay Safety considerations Engineering & implementation time of bays and Enabling wide area protection and control Decade Ahead: AC backbone to transit from 765 kv to 1200 kv Expansion of HVDC for bulk power transport and reactive power control Expansion of Digital Substation technology Renewable Management to be part of Grid Control Centres Smart Grid: Transmission Grid already smart due to extensive deployment of technologies Smart Distribution Grid thru Smarter Substations, Smart Power Quality Metering, Demand Response and Storage technologies Presentation title - 18/03/2015 P 9
