White Oak Microgrid
Definition White Oak FDA Microgrid
Local Power Generation • 26MW power supply (currently being
expanded to 55MW to handle the
installation’s peak load)
• Leverage waste heat (CHP) to condition
buildings
• Puts more power on the grid than it takes
off
Co-exist with the utility • Works in parallel with Pepco under a three-
party Interconnect Agreement.
• Participate in demand response events
• Utilize spinning reserve to maintain energy
surety
Can operate totally independent of utility grid Operate mission critical functions independent
(islanding capability) of Pepco, enabling FDA to continue
operations regardless of what happens
outside the campus
Ability to manage and control your local load • Match load to supply
•Ability to make power purchase decisions

Additional Value:
•Expanded Auto Load Shed Scheme
•Additional Dual-fuel Generation Assets
•Combined Heat and Power – maximizing BTUs
•Interconnect agreements with the utility
