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
