What are typical applications of stationary energy storage systems?

• A. Grid stabilization, peak shaving, renewable energy integration, backup power, and load leveling.
• B. Vehicle propulsion and heavy machinery.
• C. Medical imaging.
• D. Cooking and heating.

Answer: (A)

Stationary energy storage systems are placed in fixed locations to support electrical grids and facilities by storing energy for times when it’s most needed. The typical uses include stabilizing grid frequency and voltage so operations stay reliable, and reducing peak demand so overall energy costs and stress on the system are lowered. They also help with renewable energy integration by holding excess generation from solar or wind and releasing it when generation dips or demand rises, which smooths out variability. Backup power is another key role, providing electricity to critical loads during outages and maintaining essential services. Finally, load leveling aims to even out energy use over time, shifting consumption from high-demand periods to more favorable times.

Options that focus on mobile applications, like propulsion for vehicles or heavy machinery, or contexts such as medical imaging or cooking/heating, don't illustr​ate the typical use of stationary storage in a utility or facility setting.
