NEED FOR ADEQUATE TRANSMISSION STSYEM

• Generation capacity addition – limited chances• Existing generation mainly in Central / Southern

parts of Kerala• Demand in northern parts of Kerala increasing

at faster rate• Increased import requirement to meet demand• Transport of power to load centres

TRANSMISSION TO FECILITATE

• Import of sufficient power from outside• Evacuation of power from generation projects

within state• Efficient transfer of power to load centres• Grid map

• Kerala• South India

IMPORT OF POWER

• Existing system• Total capacity

• 4500 MW (Possible 2000 MW only due to constraints)

• Constraints• Inter regional• S1 - S2 corridor congestion• Overloading of inter state lines to Kerala

IMPORT OF POWER contd

• Future import requirement• Proposals to increase import

• Sufficient to meet demand up to 2031-32• 400 KV link between Trivandrum – Tuticorin for future

EFFICIENT TRANSFER OF IMPORTED POWER

• 400 KV network within state required– Proposed works• Madakkathara - Areacode DC line by 2017 - 18• Areacode – Mylatti DC line by 2018 - 19

POWER EVACUATION FROM GENERATION PROJECTS

• Proposals for power evacuation from new generation projects

STRENGTHENING OF EXISTING NETWORK

• To overcome inadequacies– Proposals

• To meet the future demand– Projected demand– Existing substations– Future requirements• 400 KV substations• 220 KV substations

MAJOR ISSUES

• Objection from landowners• For cutting trees• For placing towers

• Delay in land acquisition• Contract failures

REMEDIES

• Narrow based towers / Monopoles• Multi voltage / multi circuit towers• EHT UG cable• Submarine cable• HVDC transmission• Higher capacity conductors / HTLS conductors• GIS / Hybrid stations• Existing ROW for new lines• Simplify LA procedure• New system for tendering / selection of

contractors• Timely decisions / Timely payments• Route/Technology options

• Discussion with political parties

ACTION REQUIRED

• Completion of ongoing projects on war footing

• Timely completion of already sanctioned lines• Follow up action with CEA / SRPC/ PGCIL• Renovation / up gradation of existing system• Adopting new technologies and new systems• Long term planning
