The Japanese government has set a power sector goal for photovoltaic (PV) power usage to reach 53 million kW by 2030. To achieve the large-scale introduction of PV, a large storage capacity, in the form of pumped storage systems or batteries, is needed to store surplus electricity from PV plants. At the same time, in the transport sector, the electric vehicle

There are four major benefits to energy storage. First, it can be used to smooth the flow of power, which can increase or decrease in unpredictable ways. Second, storage can be integrated into electricity systems so that if a main source of power fails, it provides a backup service, improving reliability.
In a case study of a system with load and renewable resource characteristics from the U.S. state of Texas, we find that energy storage delivers value by increasing the cost-effective penetration of renewable energy, reducing total investments in nuclear power and gas-fired peaking units, and improving the utilization of all installed capacity.
In general, they conclude that storage provides only a small contribution to meet residual electricity peak load in the current and near-future energy system. This results in the statement that each new storage deployed in addition to the existing ones makes the price spread smaller, see Figure 16, and, hence, reduces its own economic benefits.
The model found that one company's products were more economic than the other's in 86 percent of the sites because of the product's ability to charge and discharge more quickly, with an average increased profitability of almost $25 per kilowatt-hour of energy storage installed per year.
Historically, companies, grid operators, independent power providers, and utilities have invested in energy-storage devices to provide a specific benefit, either for themselves or for the grid. As storage costs fall, ownership will broaden and many new business models will emerge.
The major result is that the perspectives of electricity storage systems from an economic viewpoint are highly dependent on the storage's operation time, the nature of the overall system, availability of other flexibility options, and sector coupling.
