Super set to build hybrid power plant published : 12 Jul 2021 at 04:30 SET-listed Super Energy Corporation is planning to develop Thailand's first power plant based on hybrid renewable resources under a "firm" power purchase agreement (PPA). A firm PPA refers to a steady supply of electricity provided to the Electricity Generating Authority of Thailand (Egat). Usually renewable power, except electricity produced by refuse-derived fuel, is in the non-firm PPA category. Sun, wind and biomass are intermittent sources of power because their production depends on weather conditions and seasons. Jormsup Lochaya, chief executive and vice-chairman of the Super Energy board, said the company will develop the hybrid renewable project this year and expects to start operation by the end of next year.
