ON-SITE ENERGY GENERATION UTILIZATION LIST

developed by Scott Sklar, The Stella Group, Ltd, 2004

Federal facilities use energy and technologies today that cost-effectively and reliably provide energy on-site. In many cases, these options off set high rates, protect sophisticated equipment from power fluctuations, obviate the need to run wires, lower noise and vibrations, lower emissions and wastes, and most importantly assure that functions continue even when the electric power grid or natural gas pipelines may be inoperative.

Battery Bank Auamentation or Displacement - Adding length of back-up power to traditional battery banks

Battery Charging (small electronics - lap tops, pdas, computers, walkie-talkies) - Small power (under 100 watts)

Building Air-Conditioning and Lighting - Solar thermal driven absorption coolers use concentrated solar by day and natural gas, landfill gas, biogas and propane when the sun doesn't shine

Cathodic Protection (rust prevention) - A portfolio of small electric producers including fuel cells, heat engines, microhydropower, photovoltaics, and small wind

Diesel Generator Replacement - Same portfolio as above, but in many cases hybridized or with batteries

Lighting (outside area, motion detector and remote liahting) - Solar and wind lighting systems attached to building, light poles, or specialized for safety

Monitoring and/or Surveillance (cameras, motion detectors, sensors) - Low power operation - primarily solar and small wind. Power quality - dedicated sophisticated controls and digital equipment such as communications and computers that are susceptible to surges, swells and transients from the electric power grid

Power Reliability (communications and computers) - Absolute reliable back-up power for days, weeks or longer

Remote and Moveable Power Gen Sets - Using shipping container and pontoons, several systems are "plop and drop" and have quick connectors to add or rotate generation

Truck Idling Displacement - Scaffolding at truck stops or loading points which provide energy and in some cases even cooling/heating, telephone, television and internet access from truck cab

Uninterruptible Power System (UPS) - A portfolio of distributed generation devices which range from 1 kW to 250 kW, on skids, and standardized. Some systems can be leased.

Waste Heat from Pipeline Pumps - Utilization of waste heat from pipeline compressor pumps and industrial processes in 55kW or 250 kW increments of electric power

Water Pumping and Pipeline Pumps - Solar and wind water pumping from 60 hp and 600 hp size which can be remote or grid-intertied, and industrial pump back-up or augmentation (meaning offsetting grid power or back-up reliability)

RECENT HIGHLIGHTS:

• FAA and State of Maryland - 1 kW fuel cells systems to back up communications: FAA Radar communications at McCord AFB and State of Maryland Emergency Communications System. A vista Labs (W A)
• Drop and plop" photovoltaics, wind and minifuel cell standardized systems on shipping containers. SkyBuilt (V A)
• Solar-driven water pumping 60 horsepower (through 600 horsepower) at Joshua Tree Park (CA) . WorldWater (NJ)
• Substation Augmentation using concentrating solar tied to aRC heat engine (used by geothermal industry) at 1 megawatt for Arizona Public Service. Solargenex Energy LLC (NC) and Ormat (NV)
• TruckStop Non-Idling Installations in Tennessee, New York and five other states. IdleAire (TN)
