Energy Storage ApplicationsDistributed Generation and Grid Support

• Demand Management– Arbitrage– Peak Shaving– Congestion Charges

• Capital Deferral– Substation Upgrade– Transmission and Distribution

• Enhanced Power Quality• Increased Efficiency

– Reduces Spinning Reserve– Reduced Cost for T&D Losses

• Load Following• Frequency Regulation• Reduced Financial Losses

from Improved Electric Reliability

• Renewable Support

Transmission, Distribution and Substation Capital Deferral

• Install Near End Use• Upgradable in Smaller Steps • Defer Until Complete Upgrade

is Necessary• Life Extension by Reducing

Load• Potentially Most Valuable

Attribute

•Upgrade in Right-Sized Increments•Address Temporary or Seasonal Loads
