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
ESPC III Base – Major Physical Features • 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)
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 MMBtu • ESPC 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
