2012PresidentialExecutiveOrder:NationalGoalof40GWofnewCHPinstalledby2020
• Most CHP owned by non‐utility sector
• 82 GW of CHP capacity at more than 4,100 industrial and commercial facilities
• Approximately 8% of current U.S. generating capacity and more than 12% of total MWhgenerated annually
• According to IDEA, District energy CHP systems in cities and university campuses represent approximately 5 GW of installed CHP

• Economic Advantage• CHP projects succeed because of low gas prices
• High total system efficiency
• Sustainability Advantage• Lower carbon footprint and CPP ERCs
• Improved public perception
• Reliability Advantage• Islanding and microgrids• Relieve grid congestion
NATURAL GAS PRICES ARE HISTORICALLY LOW AND PROJECTED TO STAY LOW FOR THE LONG‐TERM – DRIVER FOR CHP
