Battery = Storage


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

Historically used for off grid applications

Common uses for storage:

-Off Grid

-Backup Power-Reducing Peak Demand Charges

-Self Consumption


Storage becomes much more

important as intermittent and

variable generation becomes more prevelant

-Off Grid

Customers will want less maintenance

and less inconvenienceAlternative for loss of net metering

MicrogridDeveloping countries


Going off-grid with a storage-plus-solar system increases the LCOE by $0.23/kWh on average, which

more than doubles the cost of electricity for an average home.Credit: Hittinger/Siddiqui



-Backup Power

Customers will want less maintenance

and less inconvenienceMicrogrid

Generally not cost efficient

Borrego Microgrid – SDG&E



-Peak Demand

Generally commercial and industrial



-Self Consumption

largest future use

“hide” the distributed generationnecessary in some markets (Hawaii)

Where do we put the storage?

-In front of the meter

utility-behind the meter

homes and businesses


In front of the meter
