Energy supply is one of the major concerns of the world today. With uncertainty in the supply from the main oil producers arising from various reasons and the continued demand for oil by the developing nations, the oil prices are expected to remain high. Since oil is the primary source of fuel for the production of electricity by most of the world’s power plants, the shortage of fuel would cause major catastrophe in our daily activities. Thus, to counter this scenario and overcome the problems resulting from the depletion of proven fossil fuel resources, various measures have been taken. One such measure is the establishment of an alternative source of energy such as the renewable energy. One of the renewable energy sources is biomass residues, which is widely available especially in the ASEAN. The EC-ASEAN Cogeneration Programme, one of the collaborative venture between ASEAN and EC has come up with a number of successfully commissioned Full-Scale Demonstration Projects (FSDP) using biomass residues. Four of the FSDPs located in Thailand and Malaysia have been connected to the grid. These projects have been operating very well and since the biomass fuel is easily available in the ASEAN region, replication should not pose any problem. Thus, this article would highlight the success stories in implementing biomass residue-based grid-connected projects through cooperation between the ASEAN and the EC.
