Battery = Storage
HOEPER GREEN POWEREnvironmentally Friendly Building Solutions
Why do we need storage?
Why Energy Storage ?
o I want to reduce my utility costs
o I often experience power outages
o I want to be more energy independent
o I want to have reliable power off the grid
o I want to be prepared against natural disasters
o My electricity provider makes it difficult to go solar

Common uses for storage:
-Off Grid
-Backup Power-Reducing Peak Demand Charges
-Self Consumption
HOEPER GREEN POWEREnvironmentally Friendly Building Solutions
Storage becomes much more
important as intermittent and
variable generation becomes more prevelant
