1 Community Energy Planning Ken Smith President & CEO

2 Community Utility District Energy was initiated as 501(c)3 non-profit utility in 1979 District Cooling added in 1993 St. Paul Cogeneration added in 1998, forming what is now No stockholders, cost-based rates Public-private partnership city, county, state, federal agencies BOMA, chambers of commerce, industry Compete for business 80/60% market share for heating and cooling respectively

3 Our Background System developers, operators, and managers Hands-on experience in engineering, system development, and community energy system ownership and management Experts in implementing unique solutions to create advanced, integrated energy systems

12 Thermal Policy & CHP

13 Wasted Energy Source: Recycled Energy Development, data from US Energy Information Agency

14 Some 60% of primary energy is lost as waste heat. -Energy Efficiency, p. 9 September 2011

15 System Efficiency

16 Applications for CHP Large CHP (>20 MW) Industrial sites Colleges and universities District energy systems Mid-Size CHP (1-20 MW) High-growth industrial applications Manufacturing and assembly plants Institutional, military and government facilities Large commercial sites District energy systems Small CHP (<1 MW) Source: DOE Office of Energy Efficiency and Renewable Energy

17 Minnesota CHP Generation Summary Minnesota CHP Generation Summary Data as of January Number of CHP System Installations: 35 State CHP Generation Capacity (MW): 918 State Total Generation Capacity (MW): 14,715 State CHP Generation Capacity (%): 6.2% Average CHP System Capacity (MW): Median CHP System Capacity (MW): 5.00 Source:

18 Recovering Stranded Energy Capturing wasted heat that a building, industrial site or power plant is already emitting Use recovered heat to generate clean thermal energy (hot water, steam, chilled water) or clean electricity. Opportunity to vastly improve industrial energy efficiency, competitiveness of U.S. industrial sector, and provide a source of pollution-free energy
