Coal

Hydro• Hydro potential in NER and

upper part of NR

• Coal reserves mainly in ER

• Distribution of energy resources and consumption centres are extremely unbalanced

• To achieve economy of scale in the delivered cost, power transportation from pit-head generating stations is cheaper option

Necessitate establishment of large no. long distance lines & interconnection of all the five(5) Regional Grids

• National Grid planned in a phased manner• Phase-I envisaged Interconnection of Regional Grids

through HVDC Back-to-Back links having cumulative capacity of 5000 MW has been completed in 2002

• Present inter regional capacity is 9500 MW• It is envisaged to have 37,000 MW inter regional

capacity by 2012 comprising of high capacity HVDC and HVAC lines (both 765kV and 400kV) and 50,000MW by 2016

Development of National Grid

• To conserve the Right-of-Way while meeting the power transfer requirement of immediate as well as long-term – Technology adopted for progressive enhancement of

transmission capacity of same Tr. corridor through –• High capacity 400kV (quad) lines• 800kV EHVAC line initially operated at 400kV• High capacity 800kV HVDC systems initially operated at

600kV• Series compensation and TCSC• High temperature endurance conductor like INVAR• Multi-ckt. line and compact towers (ROW for 800kV line 85 m to 64 m)

– Optimal utilisation of existing infrastructure through –• Series Compensation• Uprating/Upgrading of lines• Enhancement of thermal capacity of line (75 -850 /950 C)

Technology Integration

HVDC Systems• Existing

– Rihand – Dadri 1500 MW, +500 kV – about 800 km– Talcher – Kolar 2000 MW, +500 kV – about 1450 km– HVDC Back to Back links

• Vindchyachal 500 MW : North-West• Gazuwaka 1000 MW – East – South• Chandrapur 1000 MW : West – South• Sasaram : East : North

HVDC System – For Future• Balia – Bhiwadi 2500 MW, +500 kV : Under

advance stage of investment approval. To be implemented by 2009-10.

• Upgradation of Talcher – Kolar by 500 MW• To transfer power from NER, feasibility of

HVDC bipole of 6000 MW, +800 kV is being explored.

• More HVDC links envisaged from NER
