In recent years, there has been growing interest in combined heat and power (CHP), also called cogeneration. CHP works by using modular turbines connected in parallel to generate electrical power on site, capturing the heat created, and using it to heat the facility in winter, and drive an absorption chiller in warm months.
So, why is a technology that has been around since Edison creating interest from industries as diverse as manufacturing, shopping malls, and health care? Three reasons: efficiency, money, and independence.
