Founded in 1986, PESCO set out with a purpose to provide reliable, specialized engineering services in an emerging field.

Over 40 years of dedication and discipline have shaped PESCO into a trusted one-stop service contractor for mechanical, electrical, and plumbing (MEP) systems —and one of Thailand’s leading engineering companies, delivering quality that endures.

With more than 500 permanent, well-trained, and highly experienced staff, supported by modern tools, equipment, and facilities, we have completed and designed over 300 construction projects for some of the largest local and international companies in Thailand. Our expertise spans across mechanical, electrical, and plumbing systems—ensuring efficiency, safety, and reliability at every level of clients facility.

Beyond MEP, PESCO also leads the way in clean energy solutions. With over a decade of experience in Engineering, Procurement, and Construction (EPC) of solar power plants, we have successfully delivered projects exceeding 200 MWp COD and earned recognition as the Best Electrical Contractor in Southeast Asia. Our EPC services cover everything from permits, design, and budgeting to turnkey delivery—providing clients with seamless, future-ready energy solutions.

To ensure precision and efficiency, we operate with a 3,300 sq.m. central warehouse in Lat Lum Kaeo and dedicated on-site project staging areas, streamlining logistics and safeguarding project timelines.

At PESCO, we don’t just build systems—we build trust, efficiency, and long-term value. For four decades, our guiding motto has remained unchanged:
