* VSPP = Very Small Power Producers
Economy of wind turbine operations in Thailand
Taken from Economic evaluation of wind project and
cost trend [by EGAT]
EGAT power development plan 2007
Electrical Generation Authority of Thailand
Wind energy is ‘not reliable’ Wind energy production is not
included in the plan Wind energy is supported
Unreliable wind energy projects
Large number of wind energy project proposals exceeded EGAT planned allocation
Pending and new proposals are regulated 200 THB/kW* deposits are imposed
* Approximately 5.99 USD/kW or 38.31 RMB/kW
