Also, the blending of biodiesel at various ratios will be encouraged for other specific purposes, for ex- ample, to fuel agricultural machines in rural communities and to use in combination with natural gas for buses of the Bangkok Mass Transit Authority (BMTA). Raw materials suitable for biodiesel production are raw palm oil and used cooking oil. • Promotion of Renewable Energy Utilization in Power Ge- neration This will help not only diver- sify fuel sources for power genera- tion and reduce energy import but also develop alternative energy op- tions to enhance the power system stability through the use of clean and environmentally friendly energy. Focus is made on four renew- able energy sources of which the domestic potential is high, namely: solar, wind, biomass/biogas and mini-hydro. • Solar Energy With regard to the PV techno- logy for power generation, about 6 MW of PV applications has been reported so far. Most of them are in remote areas and are off-grid, such as solar cell battery charging stations, PV pumping for village water sup- ply and integrated systems of PV/ wind turbine/diesel engine for power generation in national parks and wildlife sanctuaries. One major grid- connected project is EGAT’s 500- Figure 4 Biodiesel Van kWPha Bong Solar Cell Power Plant operated by EGAT in mountainous Mae Hong Sorn province in north- ern Thailand. The opening ceremony of this largest solar cell power plant in Indochina, worth 187.11 million baht, was launched on 23 July 2004. It is expected to help reduce diesel consumption by 215,385 litres/year. In addition, the government has a policy to speed up electrification nationwide. Pursuant to this, the Pro- vincial Electricity Authority (PEA) is carrying out a project on “solar home system” to electrify about 250 thousand households in remote rural areas, which will be more cost- efficient than the conventional grid- connected extension. The project is to be accomplished by 2007, account- ing for a total capacity of 24 MW. By 2011, it is targeted that 250 MW of the PV system will be in- stalled. Of this, 140 MW will be boosted via the RPS to be imposed on new power plants. The remain- ing 86 MW will be promoted by incentive measures to cover stand- alone systems in remote areas and PV rooftop for factories, buildings, private homes and government build- ings mainly for on-site consumption. Promotion has also been made on the use of solar thermal energy in the form of solar water heaters for use in households and new buildings, solar herbicide extracting system units, and solar dryers in the indus- tries that require the drying process, such as vegetable and fruit drying. Financial support from the ENCON Fund is provided to help reduce the system installation costs.
