Founded in 1982 as a distributor of power equipment by Mr. Gunkul Dhumrongpiyawut, who has extensive experience and strong relationship with local government authorizes in the Thai power space.

This integration allows GUNKUL to not only transform its business model from the volatile trading and EPC business to the highly stable solar and wind farm business, but also to capture on a timely basis the growth potential of Thailand’s over 1,800 MW solar power capacity slated for completion by end-2015
