This article examines emerging trends in BESS applications, including advances in battery technologies, the development of hybrid energy storage systems (HESSes), and the introduction of AI-based solutions for optimization. By storing energy from both renewable sources, such as solar and wind, and the conventional power grid, BESSes balance supply and demand, stabilizing power. . As global energy consumption increases and renewable power sources continue to rise, the demand for advanced energy storage systems has never been greater. In 2025, battery technology is undergoing a major transformation — shaping the future of everything from electric vehicles to off-grid solar. . We expect 63 gigawatts (GW) of new utility-scale electric-generating capacity to be added to the U. power grid in 2025 in our latest Preliminary Monthly Electric Generator Inventory report. This amount represents an almost 30% increase from 2024 when 48. 6 GW of capacity was installed, the largest. .
At its core, grid-side energy storage relies on a combination of hardware and software components. The hardware includes large-scale batteries—such as lithium-ion, flow batteries, or emerging solid-state types—that store excess energy during low demand periods. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources. . Electrical Energy Storage (EES) systems store electricity and convert it back to electrical energy when needed. 1 Batteries are one of the most common forms of electrical energy storage. The first battery, Volta's cell, was developed in 1800.
