Electricity demand is not constant throughout the day. This forces energy suppliers to use less efficient generators which can be easily turned on and off to match demand. By storing electricity when demand is low and expending this electricity when demand is high electricity demand can be flattened, allowing for the use of more efficient generators. This study investigates whether or not this can be economically viable at a residential level. This study found that for none of the storage technologies or pricing schemes studied was this application economically viable. It was found that the initial cost and the replacement costs were the bulk of the costs, and that efficiency is the most important factor to the amount of revenue generated by the system.
