Distributed generation

Distributed Generation

NRG Energy Centers, which include district energy systems, are energy-efficient, highly reliable and environmentally sound methods of heating and cooling multiple buildings from a single source. CHP plants generate power and use heat from that process to create steam and/or chilled water.

Each facility has a unique configuration and set of services offered. Some heat, some cool and some do both. Others provide steam for industrial processes. Several systems serve one or two large users, while others serve hundreds of customers of all types and sizes within the core of major U.S. cities.

Our Energy Centers provide district heating and/or cooling to more than 10 million square feet of building space nationwide, including hospitals, hotels, commercial office buildings and sports arenas.

The next cogeneration

CHP, also known as cogeneration, captures the heat in waste exhaust gas and turns it into useful energy by converting it into steam, hot water or even chilled water that can then be distributed to users based on their needs. We operate our network of CHP facilities with professional teams that are available 24/7. The CHP process is inherently more efficient than and nearly half as fuel-intensive as traditional generation technologies. This reduces energy costs and emissions and, in some locations, enables real-time sales of power back to the grid.

A few operational details of some of our CHP plants:

  • University of Bridgeport – providing thermal energy and electricity to the campus through a highly efficient fuel cell provided by FuelCell Energy
  • Arizona State University – providing heating, cooling and electricity to the university's distribution system connecting 88 buildings on ASU's Tempe campus and its research facilities
  • University Medical Center of Princeton – providing power, steam, chilled water and backup power to this new, state-of-the-art hospital campus
