1. BANGALORE TRANSMISSION PLANNING

2. PRESENT SCENERIO
Peak Load recorded for the state was 9503 MW at 19hrs on 7th April 2014.
The load met in Bangalore city during peak load of the state was 2314 MW with existing transformation capacity
400kV MVA.
220kV MVA.
66kV MVA.

3. PLANNING CRITERIA
Criteria for single contingency (N-1): Outage of single circuit but without load shedding/ rescheduling of generation
Criteria for second contingency (N-1-1): Outage of double circuit but without load shedding/ rescheduling of generation
Criteria for single contingency (N-1): (TRANSFORMERS): Outage of any single unit would not overload the remaining ICTs or the underlying system.

4. PLANNING PROCESS
Bangalore city is modeled for peak load recorded for the state (9500MW).
Load flow studies for existing transmission network of Bangalore area considering,
immediate strengthening required in the system
For different contingency and operating conditions (in certain critical conditions)
Future planning to meet the load growth, in order to overcome congestion and ensure reliable power supply to consumers

17. Yeramarus Evacuation Scheme (Proposed)
Phase-1
To Establish 400/220 kV substation at Gulbarga.
To Establish 400 kV pooling station near ‘BTPS’.
To Establish 400 KV switching station at Chikkanayakanahalli (C.N Halli) near “Loop in Loop Out” (LILO) point of the existing 400/220 KV sub-station at Hassan.
400 kV DC Line with Quad Moose Conductor to link ‘YTPS’ with the proposed 400 kV pooling station near ‘BTPS’. ( 150 kms)
