3. The Role of Storage Batteries and Their Importance
Storage batteries play a role in coordinating supply and demand by storing electricity during periods of low demand and releasing it during periods of high demand to level out peaks, thereby improving the stability of the electricity supply. In addition to improving energy efficiency and promoting the use of renewable energy through this technology, storage batteries complement weather-dependent renewable energy sources, which tend to be unstable in terms of power generation, by storing surplus power and using it when needed, thereby promoting more efficient use.
Furthermore, the biggest advantage for consumers is that usage fees can be significantly reduced.
By reducing electricity consumption during peak hours, electricity rates can be leveled out, thus avoiding high electricity prices (maximum demand) that, once raised, do not fall thereafter, and reducing overall electricity costs. This improvement in cost efficiency is especially important for companies.
On the other hand, since more than 70% of Japan’s power supply composition is provided by thermal power generation, the use of storage batteries is also suitable for environmental considerations, as they promote the use of renewable energy sources, thereby reducing dependence on fossil fuels and contributing to CO2 emissions reduction.
4. stability of power supply in case of “what if” situations
Above all, storage batteries are capable of supplying power even in the event of a power outage, and are therefore seen as a powerful tool for ensuring the continuity of critical infrastructure and services. This is because storage batteries are expected to play an important role in times of disaster, especially in critical facilities such as hospitals and data centers, where the stability of power supply is enhanced, and in high-rise buildings, where human lives may be at stake depending on whether or not elevators are in operation.
Conclusion
Increasing energy demand and peak load problems are having a significant impact on the stability of the power supply.
In this context, storage batteries are expected to be realized as a sustainable energy system, as they promote the efficient use of energy and renewable energy, thereby contributing to cost reduction and environmental protection.
