Seo Eng Joo: Building a Sustainable Business with Sembcorp Solar

September 19, 2025

Seo Eng Joo - a homegrown SME in the cold-chain logistics industry - made a decision seven years ago to take control of their energy future. Running 24/7 operations for energy-intensive freezers and warehouse is challenging, as they face mounting energy demands and growing expectations to be sustainable. To manage rising electricity costs and reduce their environment impact, they took the initiative to start their journey towards greater efficiency and lower emissions by partnering with Sembcorp Solar Singapore.

"Building a sustainable future is at the heart of our family values. Partnering with Sembcorp Solar helped us to transform these values into real impact." 

- Charlie Seo, Business Development Director 

Since installing Sembcorp's Solar PV system with a contracted capacity of 775kWp, Seo Eng Joo has consistently reduced its electricity costs year-on-year. The solar installation has proven to be a reliable source of energy savings, delivering average annual cost reductions of approximately $20,000 from 2019 to the present.

Their decision wasn't just about immediate savings. It was a strategic move to stay resilient and relevant in a changing energy landscape. That forward-thinking mindset continues to shape their path. 

Besides incorporating solar energy their operations, Seo Eng Joo's sustainability path also involved the upgrading of old inductions lighting to LED in phases, and their warehouse lighting is currently being upgraded to LED lighting with motion sensors, Seo Eng Joo also sends materials such as plastics and paper carton boxes for recycling.
