An Introduction to Microgrids

A microgrid is a flexible and localized power generation system that combines multiple assets. While each system is unique, they all share common elements. A microgrid utilizes renewable energy sources such as solar panels, wind turbines, battery storage, diesel gensets and combined heat and power (CHP) modules–operating separately or in parallel.
