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

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
cross-border 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.
![Page 14: Economics of Regional Energy Cooperation: Nepal Case Study](https://reader036.vdocuments.site/reader036/viewer/2022062222/5681677d550346895ddc839a/html5/thumbnails/14.jpg)

Methodology Power transfer analysis based on load flow model of India-Bhutan-
Bangladesh-Sri Lanka (>3200 buses)
NATGRID optimisation with DC approx. to load flow using equiv network (40 nodes, 166 lines)
NATGRID run without interconnector
Benefit = Difference in cost without and with link
NATGRID run with interconnector
Equivalent network
Scenarios
Comparison of scenarios

15
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
![Page 16: Economics of Regional Energy Cooperation: Nepal Case Study](https://reader036.vdocuments.site/reader036/viewer/2022062222/5681677d550346895ddc839a/html5/thumbnails/16.jpg)
16
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.

17
Economic Benefits ….. Project estimated to cost $186 million
inclusive of in-country transmission network strengthening to support 1000MW of cross-border flows
The study analysed 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

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
