In this blog, Jyoti Bisbey explores why seawater air conditioning (SWAC) and deep-water district cooling are emerging as compelling opportunities for private investment—particularly in small island developing states like Grenada. Drawing on global examples from Toronto, Tahiti, and Honolulu, the piece highlights how these systems deliver significant energy savings, reliable long-term revenues, and measurable climate benefits. It outlines practical PPP models and contract structures that can unlock bankable, low-carbon cooling infrastructure—positioning SWAC as both a climate solution and a scalable investment asset class.
