Clear answer
Clear answer, explained.
Battery energy storage systems (BESS) provide immediate backup power when the grid fails, maintaining electricity for critical systems. When integrated with solar or microgrid infrastructure, batteries can store renewable energy and continue supplying power during extended outages. They also help stabilise voltage and frequency, ensuring reliable operation of communications equipment, lighting, medical devices, and emergency coordination systems.
