Multiple applications served by an Energy Storage System

Enable integration of more renewables

Improve integration of energy generated from photovoltaic

and wind turbines and maximize returns from these assets

Optimize transmission and distribution systems

Defer upgrades, relieve congestion, control voltage, provide

reserves, and improve grid reliability

Enable micro-grid development

Create a new and more flexible grid by combining smart devices and local generation with energy storage

Reduce energy costs

Enable demand side load management to reduce demand

charges and take advantage of differential energy prices


Issues Facing T&D Operators…

• Integration of increasing penetration of variable renewable generation

• Increase in distributed generation

• Aging infrastructure and capital allocation

• Rapid Load growth

• Threat from self-generation



Issues Facing Building Owners...

• Increasing demand charges

• Increasing frequency of power outages

• Participation in demand response programs

• Significant changing time of use energy charges

• Threat of net-metering changes reducing effectiveness of installed PV



Issues Facing Renewable Operators…

• Increasing Ramp Rate Requirements imposed by Grid Connection Codes

• High Grid Connection Charges

• Day Ahead Prediction Requirements

• Declining Subsidiaries

• Output Curtailment

• Frequency Control Rules

• Increased location restrictions
