Problem Statement: Campus Facilities Master Plan (FMP) calls for adding 3.4M GSF between FMP precipitates need to study utility infrastructure; $52M in urgent renewal needs identified No support for University System or State of Maryland debt issuance Operating budget must amortize debt, and Off-balance sheet financing required

Key Issues: Availability & Cost of capital funding Impact of deal on UM balance sheet Future utility consumption profiles Anticipated impact of utility deregulation Impact of new emissions in non-attainment area Determine options for existing employees Identify technical and legal consultants Prepare performance-oriented RFP; evaluate responses Manage interest of governing board, Governor and State Agencies

Results Achieved: ò New technology doubles efficiency of CHP from 35% to nearly 70% ò Energy consumption (BTUs) reduced by 32% ò NO x, So x, PM 10 emissions 50% – 95% below thresholds established by EPA ò $120M in projected savings over 20 year term fund debt service ò Low cost, tax exempt, off-balance sheet financing achieved ò $73M in utility system improvements completed ò New technology doubles efficiency of CHP from 35% to nearly 70% ò Energy consumption (BTUs) reduced by 32% ò NO x, So x, PM 10 emissions 50% – 95% below thresholds established by EPA ò $120M in projected savings over 20 year term fund debt service ò Low cost, tax exempt, off-balance sheet financing achieved ò $73M in utility system improvements completed

Energy Savings: Trillions of BTUs Equivalent to Energy Consumed by 7,590 Homes
