Energy Storage / UPS Systems

Properly configured, energy storage benefits include:

• Improved power quality and reliability ("premium" power)
• "Green Power" dispatch/purchase options
• Reduced sizing of distributed generation systems (if applicable)
• Energy/demand cost savings from load leveling
• Decreased transmission and distribution infrastructure investment

Energy storage weaknesses include:

• High cost for long duration storage system
• Parasitic power losses to keep unit charge
• High maintenance (eg. frequent testing, charge assessment for batteries)
