Problem Statement:Problem Statement:
Campus Facilities Master Plan (FMP) calls for adding 3.4M GSF between 1990-2005
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: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:Results Achieved: New technology doubles efficiency of CHP
from 35% to nearly 70%
Energy consumption (BTU’s) reduced by 32%
NOx, Sox, PM10 emissions 50% – 95% below thresholds established by EPA
$120M in projected savings over 20 year term fund debt service
Low cost, tax exempt, off-balance sheet financing achieved
$73M in utility system improvements completed
