13 Demand Curve for 2016 & Demand Actual met for 2016, 2017 & Demand Forecast for Demand Actual met for Forecasted Demand for Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

14 TANTRANSCO developed the 400 KV Transmission corridors in order to accommodate the wind energy 1 Tamilnadu Backbone Network 1495 CKMS Rs crores 2 Tamilnadu Wind Power Corridor 846 CKMS Rs crores 33 Tamil Nadu Inter State transfer of Power 696 CKMS - Rs crores

15 Accommodation of maximum wind generation results Deviation Settlement Mechanism Surrendering of Central Generating Stations power. Backing down power purchase from LTA/MTOA Generators. Purchase of high cost power from IPPs. Intraday purchase during sudden withdrawal of wind generation Backing down the TANGEDCO Thermal Stations. Compensation charges towards Backing down

16 To improve spinning reserve in Tamil Nadu control area, the following Hydro pumped storage projects are under pipeline. Kundah 500 MW (4 X 125 MW) expected by Sillahalla MW (4 x 500 MW) expected by Mettur 500 MW (4 X 125 MW) Tamilnadu experiencing much difficulty as there is no spinning reserve from Hydro generation, deprival of monsoon / very low hydro storage and due to less gas allocation for gas stations

17 Suggestions

18 1. Forecasting and Balancing mechanism are an essential tools to aid the integration of the increasing amount of wind energy. 2. Proper Forecasting helps us to make Renewable Energy appear more like a conventional power station. 3. Storage technology to store the renewable energy have to be cost effective. Regulations have to made. Cost for Energy Storage to be included during bidding of PPA itself. 4. Available Transfer Capability (ATC) margin between Regions to be revised practically. 5. Metering and Data storage for State and for the Country for all Generations and Demand.

19 6. Compensation have to be considered by MNRE for accommodating Renewable Energy in Tamilnadu control area for the following items for maintaining thermal units at low PLF Commercial losses to TANGEDCO on various accounts indirectly including compensation paid for the Central Generating Stations Expenditure made on to increase the Transmission corridor capability 7. Future Conventional generating plants have to be designed for low operating flexibility. 8. Strict adherence LVRT & HVRT 9. Facility / Delegation of power for real time trading of power to System Operation to avoid undue delay atleast during wind season with viable commercial implications.
