Case study: Los Angeles Air Force base.
Part of California’s “Permanent Load Shift” program, a statewide effort to reduce peak demand on the electrical grid.
The 500-kWh system provides backup power in the event of power outages.
10-20 percent of the center’s daily electrical consumption shifted to off-peak hours
The system’s reliability and multifaceted safety features were an important factor
Discovery Science Center will see reduced electrical bill

Alcatraz Island Microgrid: Summary
22
Alcatraz Island Project Timeline – Origins in 1953 (!)
- SMUD Solar Array would reduce diesel use and trim electricity costs (by $0.01/kWh) - Roof stanchions installed on the New Industries Building, but
- Protests from Historical Landmark Preservation Society brought the project to a halt - SMUD dropped out
1953: Anchor severs underwater transmission line to Alcatraz, just before the prison closed
~1976: Re-opened by National Park Service with diesel generation
1995: NPS, NREL contract with SMUD to install Solar on Alcatraz
2009: ARRA Funding enabled the $3.6MM Solar project to continue… - Greatly improved technology options = more PV in a smaller space - Positioned to be non-visible to island visitors or the shore - Inverters and Controls to operate and manage the entire island

2013 Operating Data Total solar kWh: 376,061
Average solar kWh per week: 6,964
Total generator kWh: 403,450
Average generator kWh per week: 7,471
Average island load kW: 74 Total annual consumption kWh: 654,523
Generator output % by kWh: 61.6% PV output % by kWh: 57.5%
Total days of data: 378

Island Microgrid Control Scheme
If Battery approaches minimum charge, Gen-Set is automatically turned on, synchronized
Gen-Set operates at peak efficiency to charge batteries and support Island Loads Once batteries are topped-off, Gen-Set is automatically shut down
307 kW Solar Array on the Cell house Building produces maximum power and directly powers Island AC Loads
Excess Solar Energy charges a 2 MWh battery bank
If Battery approaches maximum charge, Solar output is automatically curtailed (rare, but happens occasionally in the summer)
27
Economics of the Alcatraz Island Microgrid
Cell House roof renovations Historical preservation requirements Design-in-place battery, converter room 2010 PV panels ~$3/W
Early pilot of new microgrid technologies Achieved primary goal of fuel savings and Increased reliability
Electricity cost in 2010: $0.76/kWh Electricity cost today: ~$0.71/kWh

EMOS, and Gensets @ each site.
• EMOS master @ distribution/SCADA level.
• New, underground fiber optic comm’s backbone
• Energy Management Operating System – Microgrid Design Software – Software interface for configuring the monitoring and control
parameters for multiple assets on-the-fly – Drag-and-drop interface for quick failsafe configuration – Small-footprint Industrial PC-based configurable software (Site
Controller)
• Site Controller – On-site Microgrid Controller – Hardware platform that runs EMOS™ and Asset-Control
Software Modules – Monitors and Controls Microgrid Assets (Generators, Batteries,
Load Relays) – Remote and local access control, monitoring, and data storage
and analysis
34
What are EMOS™ and the Site Controller?
• Create a self-configuring microgrid with an electrical “one-line”
• A software application that runs on a computing platform consisting of:
1) “Drag-and-drop” graphical user interface (GUI)
2) Library of device drivers (inverters, batteries, generators TQG/AMMPS)
3) Core Energy Management Application
4) Historical Performance Database
