3. Infrastructure
 Public Works Network (PWN)
– Fiber communications system
– Designed, Installed and Maintained
by Public Works Division
– PWD IT and security requirements
– Monitor/Control/Metering
– GE Microgrid controller
– 60 motorized switches
– 11 Substations with breaker control
– 2 Cogeneration plants
– 3 Chilled water plants + small
chillers (8500 tons cooling)
– Over 50 PV systems 8MW
– 250+ building controls
– Future Sewage Treatment plant
– Future Well field operations
• Cogen plant 1 $16M
7.2MW solar turbine Taurus 70
Generates 55% of base load
55,000 + MWH/year
Collects 35 MBTU/Hr heat for heating and
cooling of 60% of the base.
• Cogen/utility plant 2 - $48M
9.2MW/ twin 4.6MW Mercury 50
twin turbine for peak following
2 - 20 MBTU/hr boilers
3- 650 ton Chillers 1 – Electric Centrifugal
2 – Absorption
Expected generation full year 55,000+ MWH
• PV systems
8MW/ 54 locations tie to buildings
Size of systems 20-1200 KW
• Battery Energy Storage System
654 KW located on 1200 KW system
• Chiller plants (8 Central plants)
8500 tons cooling capacity

4. Smart Grid/Microgrid
• DOD OSD effort: ESTCP contract
–GE systems identified as the contractor for
install
–2 year $2M contract for installation and
testing
–Limited scope using existing points
already installed to expand controls
–Scope includes
– Controller/server,
– Capacitor bank,
– power factor control
– Battery Energy Storage
–Can be disabled for manual control
• MCAGCC systems long range plan parallels
scope
–Will combine all systems into a single
control network capable of monitoring,
control, and load shedding
– Generation- Automatic function to switch
from normal to renewable and island base
– Substation- monitoring, load shedding
• Way ahead
–EMCS Fiber network must be upgraded to a
hybrid Fiber/RF configuration Completed
–New smart switches for overlapping network
Completed
–New network for substations/switches
Completed
–Power factor controls on Cogen 1 Completed
–Project P1232 - New infrastructure upgrades
for whole base island mode FY 16
• Microgrid Controller project
- Tested for initial programming
- Base had multiple changes
- Updating program with P1232
project to incorporate all
generation and electrical grid
changes
• Base currently has one of the largest
DOD type 2B Microgrid system using
Cogeneration
- Current operation automatically
picks up about 10MW of load in
utility loss and sheds as
necessary
