Assessment and Design Options of Thailand’s Feed-in Policies
Thailand has been one of the successful countries in promoting electricity generation from renewable energy
sources (RES-E). The main mechanism is driven by feed-in policies. These programs were firstly implemented as fixed
premium tariffs, so-called Adder scheme, in 2006. Since the policy implementation, it effectively stimulates the national
renewable electricity market. Renewable energy uses for electricity, in Thailand, increase steadily over the last decade. The
proportion of the RES-E generation increased from 4.3% in 2007 to 9.9% in 2014. The policies have now been in the
transition stage from Adder to fixed feed-in tariff (or FIT) schemes. The fixed FITs of rooftop solar power were initially
promulgated in 2013. Afterward, the FITs of other RES-E generations were then applied in 2015. From the ten-year
experiences, the policy implementation has achieved in attracting many private RES-E generators. The investors, however,
still face the main problems of uncertainty and discontinuity. The several policy options are then discussed.
