University of New HampshireCombined Heat Power Project Why Build a Cogeneration Plant? By-products include low-cost heating and cooling More reliable More flexibile energy sources also apply to heating and cooling, not just electricity. Cleaner air 20 tons less nitrogen oxides emitted annually 200 tons less sulfur dioxide emitted annually 34,000 tons less carbon dioxide emitted annually University of New HampshireUtility Infrastructure Project Objectives Develop a Utility Plan to meet the steam, chilled water, and electricity needs of the campus through 2025 Design and construct utility infrastructure in 2005 that will meet the short term campus energy requirements in the most flexible and economic manner Assure that expansion of utility infrastructure allows UNH to meet long term energy requirements in the most economic manner Assure that new infrastructure build-out maximizes energy efficiency, so that future energy cost avoidance will pay for the capital costs of the equipment Components of UNH Utility Needs Heat (steam) Air Conditioning (chilled water) Electricity Steam Requirements for the Future The existing central heating plant has reached capacity. Remote boilers had to be installed at Holloway Commons in order to preserve system capacity for Kingsbury Existing equipment is aging Capital cost of adding future heating capacity: In 2005, to serve 2005-2009: $10 million In 2009, to serve 2009-2015: $3 million In 2015, to serve 2015-2025: $4 million TOTAL: $17 million needed for steam capacity Chilled Water Requirements for the Future Capital costs for local building chillers: College Road, 8 buildings: $9 million Horton, McConnell, Kingsbury, Morse, Parsons, Paul Arts, Philbrook, Spaulding James area, 7 buildings: $2.2 million Demeritt, James, Kendall, Morrill, Nesmith, NH Hall, Taylor TOTAL: $11.2 million needed for chilled water capacity Electrical Requirements for the Future Substations 1 2 are 40 years old Substation 3 will need replacemen
