Energy Security (through ESPC II)

• Interconnection with Electric Grid

Two separate feeders into substation

• Underground Electrical Distribution System

• Automatic Load-Shed Scheme

• 5.8 MW Engine-Generator

Dual Fuel/Primary Power Source during early stages of campus development

• 4 - 4.5 MW Turbine-Generators

• 2 MW Standby Diesel Generator


ESPC III – Development Considerations

• Expanded Auto Load Shed Scheme

• Additional Dual-fuel Generation Assets

• Steam from CUP vs. Local Steam Generators– Labs and vivariums

• Challenging Site


• Electrical Generation Two - 7.5 MW turbine-generators (dual fuel) One - 4.5 MW turbine-generator (natural gas only) One - 5 MW steam turbine-generator Two - 2.25 MW diesel black-start generators

• Back-up Fuel Storage (80,000 gal)• Chilled Water (3 @ 2,500 tons + 1 relocated)• Cooling Towers for Chillers and Steam Condensers• Thermal Energy Storage (2 million gal)• Heat Recovery Steam Generators (132,000 lbh)• Dual-fuel Steam Back-up Boiler (one 25 KPPH)• Heating Hot Water Converters (112 MMBTUH)

ESPC III Base – Major Physical Features


CUP: Bird’s Eye Perspective


Micro Grid – Systems Integration Challenges

• Mission requirements• Procurement sequence

Multiple designers Development/communication of criteria “Consulting Party” concurrence

• Points of interface Building automation system (BAS) Plant controls Utility distribution system

• Operational constraints Mission Physical parameters Environmental requirements/ restrictions Fiscal considerations Export limitations

• Optimization elements CUP equipment deployment in response to

campus loads Campus interaction with PJM grid/ market Load management in buildings to enhance

demand response capability

• Practical challenges Grid separation Black Start recovery Building systems status/ restart Critical load management Human interaction Level of automation


ESPC Environmental Benefits

• Annual Energy Savings:Current: 640,000 MMBtuESPC III Base: 275,000 MMBtu

• Pollution Prevention (annual):Current: 50,000 metric tons CO2-equivalent

ESPC III Base: 22,000 metric tons CO2-equivalent

• Co-Generation reduces GSA NCR Demand: Response during “Gold Days” (approximately 22 MW currently; nearly 33 MW post-ESPC III Base)


Other ESPC Project Benefits

• Reduced first-cost to Government• Reduced recurring costs to Government• More energy efficient campus• Fixed accountability for systems performance• Flexibility to meet evolving program requirements• Adaptive re-use of historic structures• Demand response capability ($ to GSA)• Enhanced Energy Security

Ability to continue mission independent of the grid
