Power Assessment

• Objectives
• Identify power generation distribution
  equipment needs
• Optimize selection and application of power and
  distribution equipment

• Benefits
• Maintainability (MTTR)
• Reliability (MTBF)
• Availability
• Fuel Consumption
• Size Weight
• COST LOGISTICS BURDEN

Power Assessment Discussion Topics

• Match power system to load - right sizing
• Wetstacking occurs at light loads
• Centralized Power vs. Power Islands
• Military vs. Commercial assets
• Power Distribution vs. Power Connection
• Redundancy / Reliability needs vary by unit
• Grid Design can have dramatic impact on
  transportability
• Heating Cooling loads are single largest loads
  in most tactical systems
