Over a half century of reliable energy uilt in 1949, the original cogeneration plant “Green Steam” beneits Bhoused power boilers and steam turbines to serve Cambridge’s electric distribution system and he Boston-Cambridge “Green Steam” system integrates highly By capturing heat previously lost to the environment, “Green Steam” 80% by 2050 eicient CHP technology with a 26-mile network – making it one of the greatly improves overall eiciency and reduces regional GHG emissions. “Green Steam” supports several industrial facilities. Following economic largest and most extensive district energy systems in the United States Boston and Cambridge’s goal to reduce growth in East Cambridge in the 1960’s, the main to generate both electricity and steam.

Combined Heat and Power (CHP), or cogeneration, is an energy eicient technology that generates thermal energy (heating and cooling) and electricity from a single energy source. hrough the production of electricity, heat is produced as a byproduct and recycled into useful thermal energy. Beneits of CHP CHP systems can atain up to 80 percent eiciency, as opposed to the 35 percent eiciency achieved when thermal energy and electricity are produced separately in boilers and power plants, respectively. Less fuel is combusted with CHP systems, reducing emissions, air pollutants and costs. he ability to combine CHP with other energy sources and leverage various fuel sources also provides reliability. CHP and district energy District energy systems produce and distribute energy from a central plant and can be combined with CHP systems to further reduce carbon emissions. For example, in Boston and Cambridge, Veolia’s district energy system leverages recovered thermal energy, or “Green Steam,” produced as a byproduct of electricity generation at Kendall Cogeneration Station to supply its steam network. his CHP technology, combined with Veolia’s recent infrastructure improvements, have improved reliability, eliminated thermal discharge to the Charles River and signiicantly reduced the region’s overall carbon footprint. The Boston-Cambridge “Green Steam” system integrates highly “Green Steam” eliminates a major source of thermal pollution to the efficient CHP technology with a 26-mile network – making it one of the Charles River, improves air quality by burning cleaner fuel sources and largest and most extensive district energy systems in the United States reduces regional GHG emissions. to generate both electricity and steam. twiter: @veolia_na www.veolianorthamerica.com Resourcing the world Veolia North America 53 State Street, 14th loor • Boston, MA 02109 tel + 1 617 849 6600 [email protected] twiter: @veolia_na veolianorthamerica.com.
