ENABLING SMART GRID & METERING

1. ENABLING SMART GRID & METERING GENERATION PORTFOLIO ISSUES and OPPORTUNITIES V.N.Choudhary P.Harisinghaney

2. Enabling Smart GridIssues and opportunities for generators Paradigm Shift 120 years old Model of Centralised generation and Grid, distribution Network and Consumer Is changing

3. Reasons • Regulatory Requirements • Fuel Mid change • Availability of fuel/Constraints • Price of Conventional Fuel Soaring • Demand Response changing • Environmental Issues & Carbon Concern • Technology changes in Digital/Electronics/Communication, Tech/Computation, etc.

4. Contd. Economic reasons Inclusion of ‘ AaamAdmi ‘ Industrialisation Urbanisation

5. contd Evolution of Standards & Quality Concern Interoperability standards – an example Cyber Security

6. Concerns • Efficiency • Waste Reduction • Resource Conservation

7. Issues Mix of Generation Portfolio Changing % of Renewables & Distributed generation is going to increase

8. Alternate Sources With increase in Renewable /alternate sources in grid Intermittent nature of generation Uncertainty will increase Protection standards will change Control will change

9. CONTD. Metering will change Two way interaction Export & Import Real Time billing

10. Contd. Billing as per Time of Day Peak time rate Off Peak time rate Export rate Import rate Frequency related rate

11. Contd. Even Central generating Station will have to Adopt Advance Metering Higher sized Units 660 – 800 MW UHV transmission limes • Energy efficiency calculation • Internal energy • Reactive Power Control • Blackout & Brown out protection

12. Nature of supply varies Base Load Power supplier Peak Load power supplier Intermittent Load supplier Merchant Power supplier Captive Power supplier

13. Degree of SmartnessIncreasing Right from the beginning i.e. 1888 Now it will Lead frog Due to advanced electronics & Communication and software

14. Relevance of Smart grid elements Generation/distribution For Poverty Elimination & Inclusive growth We can use cluster approach

15. Contd. Like Intranet & Internet

16. Contd. Clusters of Renewables & alternative Resources may be Created at remote places

17. contd These clusters can be Interconnected via High Cap Transmission Lines To Connect rural ,mountain ,and desert located population clusters

18. contd Different schemes like RG GrameenVidutikaranYojna APDRP MNREGA Urbanisation PURA May be synergised to generate Energy in rural clusters as cottage industry To provide opportunity for small/home industry & employment

24. RENEWABLE ENERGY SOLAR 301 MW BIOMASS 15 MW GEO THERMAL 30 MW SMALL HYDRO 300 MW WIND 650 MW • 300MW Solar projects by 2014 • 1000MW capacity RE projects by 2017 MOUs • MoU with KPCL signed on 12.01.2009 for development of 500 MW wind energy projects in Karnataka • MoU with GPCL signed on 20.03.2010 for development of 500 MW renewable energy based projects in Gujarat • MoU with A&N Administration signed on 27.11.09 for development of 5+1 MW solar PV projects in Andaman & Nicobar. • MoU with NGRI signed on 26.03.08 for development of Geo-thermal energy based projects.. • MoU with SDC signed on 05.09.08 for development of two-stage gasifier technology. • MoU with Government of Rajasthan for development of wind and solar energy based projects in Rajasthan.

25. DG PORTFOLIO PROJECTS COMMISSIONED: No of Projects 15 Total Capacity: 300.5 kW Household/ Population 2153 /12000 • PROJECTS • UNDER IMPLEMENTATION • 01 Nos • Chhattisgarh: 01 • Capacity: 40 kW, • Micro Hydro, HH-82 • DPRs UNDER CONSIDERATION • 28 NOS. • ER-I : 16 • Coal Mines: 12 • Concerns: • Fuel availability • Gap between revenue and expenditure • Income Generation Scheme • Villages getting electrified with grid supply.

26. Basket of RE Projects Solar PV- 110MW 5MW A&N 5MW Dadri 5MW Faridabad 10MW Unchhahar 25MW Ramagundam 10MW Korba 50MW MP • 2. Solar Thermal-240MW • 15MW Anta • 25MW Singrauli • 50MW Gujarat • 100MW Karnataka • 50MW Rajasthan • 4. Small Hydro (<25MW) • 8MW project at CW outfall of NTPC-Singrauli • 3. Wind energy projects 800MW • 100MW ( Land offered by bidders) under evaluation • 100MW at Guledaguda, Karnataka • 400MW at Karnataka under identification • 200MW at Ambliyara & Vondh in Gujarat • 5. Geothermal-50MW • Preparation of FRs at Tapovan in • Uttarakand & Tatapani in Chhattisgarh.

27. Solar Resource Availability in India • 5000 trillion kWh solar radiation incident in a year over India • Radiation data collected by India Meteorological Department and some other centres • Daily solar radiation 4 - 7 kWh per sq. m. • Most parts of the country receive solar radiation sufficient enough to effectively utilize solar energy systems • Typically, 2.0 hectare of open space is required for one mega watt solar power plant

28. Road Map - Solar Cumulative MW

29. Issues of solar power • Hugh land requirement • Production of the solar cells carries an upfront cost to the environment via production, but offers clean energy throughout the lifespan of the solar cell. • Intermittent power generation & available in day time only • Low efficiency & CUF • High capital cost & high Cost of electricity generated

30. WIND ENERGY IN INDIA • Installed Capacity of India 12009.48 MW as on 30.06.2010 • India ranked 5th in the World in terms of installed capacity after USA, Germany, China, Spain. • India has a potential of 48,199 MW

31. WIND RESOURCE MAP OF INDIA

32. WIND ENERGY IN INDIA • 1150 wind monitoring stations established by C-WET • States with high potential • Tamil Nadu / Gujarat / Maharashtra / Karnataka / Rajasthan / Madhya Pradesh / Andhra Pradesh / Kerala • 216 sites with annual average wind power density > 200 Watts/m2. • Wind Atlas for India has been prepared by C-WET.

33. CRITICAL ISSUES FOR WIND ENERGY PROJECTS • UNCERTAINTY IN ENERGY ESTIMATION FROM A WINDFARM • AVAILABILITY OF LAND • SHARING OF FACILITIES • INTEGRATION WITH THE GRID • PERFORMANCE EVALUATION & TESTING • O&M • MONOPOLY OF MANUFACTURERS • COSTS & ECONOMICS

34. Initiatives in Wind energy by NTPC • 650MW capacity addition plan • Installation of 100 MW Wind Farm under process • MOU signed with KPCL for Development of 500MW wind energy projects in Karnataka • 100MW wind energy project allotted to NTPC at Guledagudda site, Distt. Bagalkot, Karnataka by GoK. • DPR finalised in-house for Guledagudda wind energy project. Approved by Project Sub-Committee of the Board of Directors • MOU with GPCL for development of wind energy projects in Gujarat

35. Hybrid RE Systems In the future, several hybrid systems consisting of wind , solar, Biomass & small hydro installations could be connected in clusters to form micro grids which can support the functions of the smart grid by firming up variable generation. These micro grids can be integrated to a larger power system or national grid. Some hybrid systems could be the combination of the following: PV/Battery, PV/Diesel, PV/Battery/Diesel, Wind/Battery; Wind/Diesel; Wind/Small Hydro; Wind/PV/Small Hydro; Wind/PV/Biomass. Small Hydro/Biomass; Small Hydro/Battery/Biomass;

36. CONCLUSION • Solar & Wind energy technologies are pollution free and environment friendly and are compatible with smart grid. • Hybrid systems shall help in firming up the variations in generation . • Wind energy has very good potential and it is the fastest growing energy source • The future looks bright for RE technologies as smart grid technology will make these installations viable and attractive for generators as well as consumers.
