Electric grid is going through a rapid transformation with significant demand growth, large scale integration of renewable energy sources, and infrastructure upgrades to support electrification and data center loads and to enhance reliability and grid flexibility. Energy storage is at the center of this transformation providing system operators with a flexible resource to support renewable integration and enhanced grid reliability. Advances in battery technologies, particularly lithium-ion batteries, have been pivotal in enabling modular storage system architectures suitable for wide range of grid applications. This lecture will explore advances in battery technologies and the engineering of large grid-scale energy storage systems, focusing on their design, performance, and suitability for utility scale applications. Additionally, it will highlight large-scale implementations, discuss emerging technology trends and address industry’s needs for the future grid.
