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

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:

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
Energy Savings:
