Boston and Cambridge, Massachusetts have decided to build a joint district energy network, using waste heat from a 256MW cogeneration plant.
The Boston Globe reported in February that, instead of dumping some 70 million gallons of waste-heat water into the river every day, the GenOn Kendall Cogeneration Station in Cambridge would convert it to steam and pipe it across the Charles River to Boston. The US $112 million pipe is to be completed by 2016 at the latest, and serve some 250 customers in the business district.
