17 5. Concluding Remarks Thailand has set a challenging gtarget via the AEDP , having electricity come from RE at 9,198 MW by Apart from reducing CO2 Emission target, it is expected to reorganize the whole electricity supply industry through the deployment of 21 st Century technologies. Smart grid technologies has come to play a key part to support this transition period, enabling more sustainable power supply & efficient energy consumptions of the country. The smart grid development is undergoing as a transition driver to the ultimate success for future de carbonized power system within the nation. 17
