The development stages:Under Construction/2014-03,In operation/2016-10.The investment is US$150mn.Developed by the US Virgin Islands Water and Power Authority (Wapa), the project involves outfitting seven oil-fired power plants on the islands of St. Croix and St. Thomas to enable them to burn liquefied petroleum gas (LPG, or propane) as the primary fuel source. By switching to cleaner-burning propane, Wapa is expecting to cut its greenhouse gas emissions by 20% as well as reducing its fuel costs by around 30%, resulting in smaller energy bills for customers.
