Technically feasible annual hydropower potential is 13,564 GWh with 75% already utilized. Installed hydro capacity is about 3,561 MW and 26 plants are owned and operated by Electricity Generating Authority of Thailand (EGAT) with around 70 MW - some 40 small and mini hydro plants - operated by Department of Alternative Energy Development and Efficiency and Provincial Electric Authority.
Under the Power Development Plan, a total installed energy capacity of 73,211 MW is targeted by 2037. Development is focusing on renewables like solar and wind, leading to an increased demand for hydropower to provide grid stability services. If the target is achieved, 11% of the installed capacity by 2037 will come from hydropower too.
