What is grid energy storage?
Grid energy storage, also known as large-scale energy storage, is a set of technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power, releasing it when needed.
How does energy storage work?
Energy storage acts as a buffer, capturing excess energy when supply exceeds demand and releasing it when needed. This balancing act ensures a steady, reliable power supply, smoothing out the intermittent nature of renewable sources. Batteries are among the most versatile and widely used energy storage options.
Why do we need energy storage systems?
A wide array of storage technologies have been developed so that the grid can meet everyday energy needs. Energy storage systems provide a wide array of technological approaches to managing our power supply in order to create a more resilient energy infrastructure and bring cost savings to utilities and consumers.
