EVACUATION CHALLENGES
FOREST MAP OF KARNATAKA
ENVIRONMENTAL ISSUES
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



LOAD-LOAD GROWTH IN NORTH COASTAL
KARNATAKA NOT COMMENSURATE WITH
THE GENERATION ADDITION.
LOAD CENTRES ARE TOWARDS SOUTH –
BANGALORE-MYSORE-MANGALOREHASSAN.
BANGALORE LOADS GROWING AT A
PHENOMENAL RATE (15%).
EVACUATION STRATEGIES
CORE 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

OPTION 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



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.



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
