KARWAR ULTRA MEGA THERMAL POWER PROJECT PROJECT

EVACUATION CHALLENGES



ENVIRONMENTAL ISSUES PROJECT

KARWAR IS IN COASTAL SURROUNDED BY DENSE FORESTS

  • FOREST CLEARANCE APPROVALS – LONGER LEAD TIMES

  • NECESSITATES QUICK FINANCIAL TIE-UPS AND STATUTORY APPROVALS

  • MAY REQUIRE USE OF MULTI CIRCUIT TOWERS TO CONSERVE ROW


TECHNICAL ISSUES PROJECT

  • LOAD-LOAD GROWTH IN NORTH COASTAL KARNATAKA NOT COMMENSURATE WITH THE GENERATION ADDITION.

  • LOAD CENTRES ARE TOWARDS SOUTH – BANGALORE-MYSORE-MANGALORE-HASSAN.

  • BANGALORE LOADS GROWING AT A PHENOMENAL RATE (15%).


Evacuation strategies core issues
EVACUATION STRATEGIES PROJECTCORE ISSUES

  • EVACUATION FOR A 4000 MW STATION NEEDS TO BE ROBUST

  • LOAD CENTRES ARE FAR AWAY NECESSIATING A NEED FOR LONG LINES

  • HOLISTIC PLANNING:-SHOULD BLEND IN WITH THE EXISTING SCHEME FOR ECONOMY AND BETTER CORRIDOR UTILIZATION

  • VOLTAGE LEVELS:-

    • 765 KV LINES

    • 400 KV D/C QUAD MOOSE

    • 400 KV D/C

Suggested Evacuation Lines OPTION 1OPTION 1

  • KARWAR-MAPUSA ( HVDC B2B LINK)

  • KARWAR-TALAGUPPA (400 KV DOUBLE CKT.)

  • KARWAR-HIRIYUR (400 KV DOUBLE CKT.)

  • HIRIYUR-HASSAN (400 KV DOUBLE CKT.)

  • NELAMANGA-TALAGUPPA BOTH 400 KV CKTS. LILO AT HASSAN

  • HIRIYUR-DODDABALLAPUR 400 KV S/C

  • HIRIYUR-ANATHPUR-DODDABALLAPUR 400 KV S/C

  • NAGARJUNA – HASSAN (400 KV DOUBLE CKT.)

  • HASSAN-MYSORE (400 KV DOUBLE CKT.)

  • MYSORE-NELAMANGALA ONE CKT. LILO AT BIDADI.


Option 1 highlights
OPTION 1: HIGHLIGHTS OPTION 1

  • THE EXISTING CORRIDOR OF TALAGUPPA NELAMANGALA LINE IS USED FOR ENHANCING EVACUATION.

  • BY PROVIDING HVDC BACK-TO-BACK CONNECTION WITH GOA, FLEXIBLE AND GUARANTEED EXPORT TO GOA (WR) CAN BE ACHIEVED.

  • CREATION OF A NEW STATION (DODDABALLAPUR) NEAR BANGALORE HAS BEEN ENVISAGED FOR ADDED SECURITY AND RELIABILITY OF SUPPLY TO AND AROUND BANGALORE.

  • TOUCH POINT HAS BEEN PROVIDED AT ANANTHPUR IN AP – GROWING LOAD CENTRE.

  • MAY REQUIRE COMPENSATION OR STRENGTHENING OF TALGUPPA-HASSAN SECTIONS.

  • N-1 CRITERIA IS BARELY MET.

Option 2 highlights
OPTION -2 HIGHLIGHTS OPTION 1

  • NARENDRA-KOLHAPUR BACK-TO-BACK LINK INSTEAD OF KARWAR-MAPUSA.

  • ADDITIONAL D/C LINE TO BASAVANA BAGEWADI TO SERVE N.KARNATAKA AND ALSO CONNECTS TO TWO HVDC B2B EXPORT PATHS

    • NARENDRA- KOLHAPUR

    • RAICHUR-PARLE

  • ADEQUATE EVACUATION CAPACITY.

Option 3 highlights
OPTION -3 HIGHLIGHTS OPTION 1

  • ADDITIONAL LINE ALONG THE COAST TOWARDS MANGALORE POOLING POINT FOR NAGARJUNA AND KARWAR POWER

    • SERIES CAPACITOR ON THIS LINE MAY BE REQUIRED DUE TO ITS LARGER IMPEDANCE

    • TALGUPPA LINE CAN BE AVOIDED IF NEED BE

  • ADDITIONAL D/C LINE TO BASAVANA BAGEWADI TO SERVE N.KARNATAKA AND ALSO CONNECTS TO TWO HVDC B2B EXPORT PATHS

    • NARENDRA- KOLHAPUR

    • RAICHUR-PARLE

  • MANGALORE-POOLING POINT TO MYSORE ALSO CAN BE CONSIDERED

    • EVACUATION IS SAME AS THE COGENTRIX PROJECT WHICH WAS SHELVED

  • MAXIMUM RELIABILITY WITH MINIMUM FOREST CLEARANCE REQUIREMENT

  • ANOTHER STATION AT HAVERI CAN BE CONSIDERED FOR EVACUATION INSTEAD OF HIRIYUR

    • LILO OF NARENDRA GUTTUR AT HAVERI

    • KARWAR - HAVERI – HIRIYUR D/C QUAD

    • THIS WOULD REDUCE THE LINE LENGTHS

    • THIS WOULD FURTHER REDUCE FOREST CLEARANCE
