Fundamentals of Battery Energy Storage System (BESS)

Fundamentals of Battery Energy Storage System (BESS) is a 3-day training course. A Battery Energy Storage System (BESS) is a technology developed for storing electric charge by using specially developed batteries.

Battery storage is a technology that enables power system operators and utilities to store energy for later use. A BESS is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.

Fundamentals of Battery Energy Storage System (BESS) training should be suitable for engineers, managers, supervisors as well as professional and technical personnel.
