The US Environmental Protection Agency (EPA) has awarded the Energy Star Combined Heat and Power award to three facilities that have used CHP technology to protect public health and the environment.

The winners are the Dominion Transmission-Crayne Station in Waynesburg, Pennsylvania; KPMG LLP in Minneapolis; and the University of Cincinnati in Ohio.

By using CHP technology, the award winners achieved an estimated annual energy savings of more than $4m and avoided carbon pollution equivalent to that from nearly 20,000 cars on the road.

The EPA says the three facilities achieved operating efficiencies ranging from 68% to 73%, much higher than the efficiency of separate production of electricity and thermal energy, which can be less than 50%.

“Combined heat and power systems are an exciting and innovative technology—it pays us back by cutting energy costs and protecting the environment,” said Gina McCarthy, Assistant Administrator for EPA’s Office of Air and Radiation. “By using this technology, our award winners are demonstrating their commitment to clean, healthy air and creating a path for others to follow.”
