Temporary Power for the Colonias — Hybrid Micro-grid On-demand Power
Problem: Remote communities without basic services (water, waste water, electricity)
Solution: Develop local temporary power microgrid in community
Funding Agency: Texas State Energy Conservationent Station Xtreme Power Solutions, Inc.
Enabling Technology:Hybrid Generation Micro-Grid
Xtreme Power’s PowerCell and associated control and switching technology allows the development and integration of a 20KW peak demand portable power system that is supplied by an integral diesel engine running bio-diesel supplemented by wind and solar cells. Power will be supplied to residents via buried cable to a power pedestal installed outside the dwelling (similar to power pedestals found in RV parks). Each dwelling will be supplied with a 15 Amp circuit limited to 1kW demand. A pre-paid system will be in-place to allow residents to purchase power from the system. The expected price for power from this system is $0.20-$0.25/kWhr.
The system envisioned will capable of supplying a peak demand of 20kW. Efficiencies resulting from the power storage system supplemented by the renewable power generation systems will allow the micro-grid system to provide power on a 24 hour basis with only 5-8 hours of diesel engine run-time.
Hybrid generation and storage system installed in trailer
PowerCell stack with associated charge controllers and inverters racked in rear
Bio-diesel generator installed in front separated from battery and electronic compartment by heat shield and partitions.
PV array mounted on roof
Wind Turbine mounted on tower next to system
System will installed in central location with grid wires to power pedestals buried in private easements.
PowerCell Specifications:
Size: 5” x 51/4” x 25”
Nominal Voltage: 12VDC
Capacity: 1.2 kWh (100 Amp-hour)
Efficiency: 98% (typical lead-acid is 55% to 91% depending upon the state of charge)
