Regional cooperation?

Wide variation in resource endowments



Full potential not exploited



Economic opportunities energy exporting countries
Enhanced opportunities for climate change mitigation
Single fuel dominance


Hydropower, coal, natural gas and other renewable energies
Sharing of low cost energy resources
Energy resource diversification and energy security
Acute power shortages

Electricity Supplies
• Region to add about
63000MW of coal power
(2012-2017)
• Will generate about 410
TWh per year
– About 390 million CO2
emissions
Hydropower (GW per 100 persons)
Coal (tons per person)
Gas (tcf per 100 persons)

SAARC Regional Energy Trade
Study (SRETS)

Proposed projects





India-Nepal power interconnections
 Dhalkebar to Muzaffarpur
 Gorakhpur to Butwal
Bangladesh-India power interconnection
 Western border of Bangladesh
 Assist Bangladesh to import power from India
Bhutan-India interconnections
 Catering increased hydropower development and crossborder trade
India-Sri Lanka interconnection
Establishment of a regional power market

Economic Benefits

Benefits of regional cooperation


Dhalkebar-Muzaffarpur transmission line
Analysis carried out with an investment
planning model


Reduced integrated South Asia
transmission network of 40 nodes and 166
transmission lines
“with” and “without” project scenarios.
13
Methodology
Power transfer analysis based on load flow model of India-BhutanBangladesh-Sri Lanka (>3200 buses)
Equivalent network
NATGRID optimisation with DC approx. to load
flow using equiv network (40 nodes, 166 lines)
Scenarios
NATGRID run without
interconnector
NATGRID run with
interconnector
Comparison of scenarios
Benefit = Difference in cost
without and with link
14
Economic Benefits …..

Generation investments


Based on generation plans of the individual
countries
Transmission capacity and electricity demand
projections


Based on the national plans
Extrapolated in certain cases
15
Economic Benefits …..



Benefit of cross-border transmission
measured
Reduced generation costs both investment
and operation
Reduced cost of unserved energy

Due to increased overall effective generation
capacity at the disposal of each of the countries.
16
Economic Benefits …..

Project estimated to cost $186 million


The study analysed






inclusive of in-country transmission network strengthening
to support 1000MW of cross-border flows
Nepal reaching a generation surplus state by 2016/17
Nepal remains a deficit state even by then
Accrued benefits $ 105-215 million per year
Cost of the transmission around $ 20 per year
Interconnector highly beneficial in both scenarios
Benefits far higher in the latter
17
Final remarks

Economic rationale for India-Nepal
interconnections is high



High energy transfers
Significant difference in economic costs
Additional benefits


Climate change mitigation
Improved reliability
