GreenYellow highlights energy savings strategies

Jeremy Colson, head of the Energy Efficiency Business Line at GreenYellow

As a key participant in the Vietnam Energy Transition Forum, GreenYellow contributed vital expertise on achieving significant energy efficiency gains without upfront capital expenditure.

On November 5, Jeremy Colson, GreenYellow's head of the Energy Efficiency Business Line, delivered a presentation focused on bridging the gap between sustainability goals and financial reality. The session highlighted how the energy service company (ESCO) model allows businesses to immediately upgrade critical, high-consumption utilities – such as ageing chillers, heating, ventilation, and air conditioning (HVAC), and refrigeration systems – by transferring the full investment cost and operational risk to GreenYellow.

The presentation drew interest from critical stakeholders within the industry. Colson moved beyond theory to showcase practical applications where businesses gain access to fully funded, multi-technology solutions with guaranteed performance and no operational disruptions.

"Companies know what needs to be done. They see the potential in upgrading chillers, optimising HVAC, and switching to cleaner energy sources, but budget constraints, technical complexity, and operational risks often stand in the way," said Colson. "That’s exactly why the ESCO model exists: to unlock savings, enable upgrades, and transfer the risk."

GreenYellow's participation underscores its commitment to leading corporate in Vietnam towards energy consumption optimisation and decarbonisation. By removing the primary financial barriers, it is accelerating the adoption of energy efficiency projects across the country.

GreenYellow, founded in France in 2007 and expanded to Vietnam in 2020, has become a major player in the energy transition, and a partner of corporates in their decarbonisation journey and quest for energy independence.
