| What are the benefits of installing energy storage systems for businesses? |
| Setting up an energy storage system can really improve the reliability and quality of your facility’s power supply. One of the most measurable benefits is shifting peak and off-peak electricity usage—charging the system at night when rates are low, and discharging during peak hours to save on costs. You can also join demand response programs to earn discounts by discharging during grid stress periods. |
| How should we determine the right capacity for its energy storage system? |
| Start by looking at your actual power usage and what you expect the storage system to do. A good rule of thumb is to base the system size on twice your contracted capacity. If your facility often exceeds that limit, consider scaling up to avoid penalties. |
| How can businesses profit from energy storage systems? |
| There are several ways to generate value. You can take advantage of peak/off-peak price differences, participate in demand response programs for rate discounts, or even trade stored energy on the market when prices fluctuate. Plus, having backup power helps avoid losses from unexpected outages. |
| Why do renewable energy systems need storage? |
| Renewables like solar and wind are intermittent—they depend on weather and time of day. Storage helps smooth out supply by saving excess energy during high production periods and releasing it when demand spikes or generation drops. This boosts efficiency, lowers costs, and supports carbon reduction goals. |
| What are the requirements for installing an energy storage system? |
| You’ll need enough space for the equipment, plus room for maintenance access and proper ventilation. It’s best to place the system close to where the power is used to reduce transmission losses. You also need a suitable grid connection point and must follow fire safety and environmental regulations. |
| Can energy storage systems be insured? |
| Yes, they can typically be covered by public liability and third-party electrical insurance. This protects against fire damage or injuries caused by system failures. However, coverage depends on the insurer’s assessment of the site’s safety design and operational standards. |
| What are common types of energy storage suitable for businesses? |
| It depends on your operations and available resources. Lithium-ion and lithium iron phosphate batteries are popular and well-developed. If you have more space, vanadium flow batteries are an option. There are also physical storage methods like pumped hydro, compressed air, flywheels, and gravity-based systems—each suited to different needs and budgets. |
| How much does it cost to install an energy storage system? |
| Costs vary based on capacity, technology, and installation needs. For lithium battery systems, expect around NT$10–12 million per megawatt-hour. Smaller setups will differ. Don’t forget to factor in installation, maintenance, upgrades, and power management systems. A detailed budget based on your usage and ROI timeline is essential. |
| How long does it take to install an energy storage system? |
| It depends on the scale and site conditions. Generally, the whole process—from application to installation—takes 3 to 6 months. This includes design, permitting, equipment selection, and procurement. Larger projects or special equipment may take longer. If no major construction is needed, installation itself may only take 1 to 2 months. |
| How can businesses reduce risks when installing energy storage? |
| Start with high-quality batteries and a solid safety design that meets standards. Use experienced professionals for design and installation to ensure compliance and system reliability. Regular inspections and maintenance help catch issues early. Also, install fire safety systems and emergency protocols—and make sure to get fire and liability insurance for added protection |
