1 Potential Gains from Regional Cooperation and Trade of Electricity in South Asia Govinda R. Timilsina and Mike Toman The World Bank, Washington, DC 5 th Asian Conference of IAEE University of Western Australia Perth, Australia February 2016

3 Presentation Outline Motivation Analytical approach Baseline results Results from full regional trading scenario Sensitivity analysis Conclusions

4 Motivation Why do we need expansion of cross-border or regional trade on electricity in South Asia? Supply deficit and huge room for demand growth Diversity on resource availability across nations and states/provinces Surplus hydro resource in some nations whereas a high demand for it in the others Peak load sharing due to seasonal disparity in demand Environmental and climate change obligations The region is lagging much behind from other parts of the world on regional electricity trading

9 The Model Our focus is on a longer-term, planning horizon; The model jointly optimizes both generation and transmission interconnection systems; Key input data include: electricity load projections; capacity and operation costs and thermal efficiencies of each type of power plant; resource profiles for renewable energy sources; and fuel prices; The methodology and key assumptions were agreed among Bank Country Office and other experts in a regional meeting held in Kathmandu in November 2013.

21 Sensitivity Analysis Seven sensitivity analysis Increased demand Increased coal price Lower availability of hydropower due to climate change Lower costs of renewables (wind and solar) Sub-regional trading instead of full regional trading Delays in planned or committed projects Carbon pricing

22 Sensitivity analysis: Higher demand growth If the electricity demand in each country grows 1% more each year than assumed in the baseline (regional demand for electricity increases 6.2% on average instead of 5.2% assumed in the baseline), then: Baseline Regional Trade Installed Capacity 24% 24% Transmission Interconnection 16% 22% Total cost for electricity supply 28% 29% CO2 Emissions 19% 21%

23 Sensitivity analysis: Higher coal price If the growth of coal prices increases by 1% more than assumed in the baseline (1.9% instead of 1% in the baseline): Installed Capacity Baseline Coal (-5%); Hydro (1%);Wind (4%); CC (43%) Regional Trade Coal (-4%); Hydro (4%);Wind (12%); CC (21%) Transmission Interconnection -15.5% -2.5% Total cost for electricity supply 6.3% 5.6% CO2 Emissions -1.6% -2.2%

24 Sensitivity analysis: Higher price and lower availability of hydro If the capital cost of hydro increases by 10% and availability of hydro generation decreases by 10% due to drought: Installed Capacity Baseline Coal (0.5%); Hydro (- 2%);Wind (3%); CC (3%) Regional Trade Coal (2%); Hydro (- 1.3%);Wind (5%); CC (3%) Transmission Interconnection -0.2% -2.1% Total cost for electricity supply 2.2% 3.6% CO2 Emissions 1.2% 2.3%

25 Sensitivity analysis: Lower costs for wind and solar If the capital cost of wind decreases by 24% (from US$1900 to US$1440/kw) and capital cost of solar decreases by 32% (from US$2200to US$1490/kw): Installed Capacity Baseline Coal (-2%); Solar (64%);Wind (25%); CC (-5%) Regional Trade Coal (-2%); Solar (98%);Wind (34%); CC (-2% Transmission Interconnection -4% -5% Total cost for electricity supply -1.6% -1.9% CO2 Emissions -1.8% -1.3%

26 Key Conclusions All countries in South Asia will gain from regional electricity cooperation over the ; the benefits-cost ratio at the regional level exceeds 5. Although the contribution of cross-border trade to meet India and Pakistan s total electricity demand would be relatively small (approximately 5%, because of their large size of demand), it would absorb almost all economic potential of hydropower resources in Afghanistan, Bhutan and Nepal. Regional trade enhances the exploitation of cleaner source of electricity generation; power sector CO2 emissions reduces by 8%.
