- Introduction Vietnam currently is an energy exporter but it would face manychallenges to energy balance and energy security in the near future. Coal industry presently plays a key position in Vietnams energysector. Studies: This study firstly gives historical story, current picture and prospectof Vietnams coal industry. The study investigates the roles of coal industry in Vietnamsenergy security with focus on power generation sector. The study proposes some solutions to the challenges the coalindustry would face.
- Historical picture & current situation Vietnams coal industry was born in 1840 when the Minh MangKing permitted mining activities in Dong Trieu district (Quang Ninhprovince) Since 1995 to present coal-mining activities have transited fromopen-cut to underground.
- Historical picture & current situationDuring the period 2001 to 2010, Vietnams coal production &consumption has been increasing rapidly. Vietnams production, consumption and export from 2000 to 2010

- Vietnams power development planVietnams power system would move dependence fromhydropower & gas-fired power to coal-fired power 2010 3% 0% 5% 35% 39% 2020 2030 19% 1% 3% Hydropower Coal-fired power 6% 5% Oil & gas-fired power Renewable energy 6% 16% 25% 17% Nuclear power Imported power 9% 12% 52% 48%
- LEAP modelFrom bottom-up: end-user accounting techniques (fuel- All costs, externalitiesdevice-end user-subsector-sector) to top-down for any pollutants,macroeconomic modeling decommission costs and unmet demand Demand side Environment costs Presenting results in LEAP Fueldemand, costs, LEAP by: Chart, table, graph, mind- un-it productions, GHG map... emission, air- pollutant, Supply sideAccounting and simulation methodologies for electricity Exporting results togeneration system and capacity expansion planning MS Excel, Power-point...The study applies a bottom-up model, the LEAP framework, to simulateVietnams power system in the next two decades with the base-year 2010.
- Scenario definitions (I) Simulate the power sectors evolutions for the next 20years with continuation of current policies in Vietnam. (II) Analyze effects of changing energy policies to totalpower demand and power generation structures. (III) Promote power generation share from renewableenergy in the power sector.Group Scenarios Demand side Supply side Baseline scenario BS Average demand forecast (PDP VII) Continuation of current policies for I High-demand HS High demand forecast (PDP VII) power development in scenario Gas scenario NS Average demand forecast (PDP VII) Increase natural gas and LNG use Replace nuclear power by coal Coal scenario CS Average demand forecast (PDP VII) II power Low demand No nuclear power, reduce coal LS Lower power demand scenario use Renewable Increase renewables resources, III RS Average demand forecast (PDP VII) scenario reduce coal use

- Results & analysisVulnerability to power sector caused by high share and highprice of imported fuel: Vulnerability index with different coal prices
- Results & analysisQuantities of Green-house gases (GHGs) from power sector Cumulative GHG emissions 2010-2030 (Million ton CO2e)
- Conclusions The higher power demand growth would be, the fasterVietnam would depend on coal power, especially thoseusing imported coal. The current power generation development plan to 2030could be the least-cost scenario but it could ensure lesssecurity of energy supply than other scenarios. Electricity import ratio in power source structure isreasonable, which could be increase to 2030 to a highervalue. Because of reliance of imported coal which shares formore 50% capacity of power generation structure,imported coal price rise could be vulnerable to thenational economy
- Recomendations To meet increasing power demand while reduce thevulnerability of the power system and improve
