Fundamentals of Battery Energy Storage System (BESS) is a 3-day course that evaluates the costs and investment benefits of using a BESS system.

Participants will also learn best practices for energy storage engineering and installation.

Battery energy storage systems (BESS) are among the most widespread and accepted solutions for residential, commercial, and industrial applications.

Battery energy storage systems power everything from our phones to cars, houses, and even retail and industrial facilities. Batteries can store electricity by converting it into stored chemical energy, which is converted back to electricity as needed.

Benefits of battery energy storage include:

  • Creates flexibility for the electric grid as outages become increasingly costly by preventing extended downtime and providing backup power when needed
  • Boosts the quality and reliability of energy delivery by providing temporary continuity during outages
  • Injects and extracts energy according to changes in load in real time
  • Reduces environmental impact through improved energy efficiency, reduced carbon emissions, and a new opportunity for renewables
  • It can significantly lower energy costs by reducing fossil fuel use and lost revenue from outages

From 2020 to 2021, the energy storage market doubled in size, and global storage capacity is expected to increase by 56% in the next five years. 

Energy analysts believe that all of this energy storage capacity will have wide-reaching effects in terms of energy efficiency and use, especially for site operators and service providers.

Many energy professionals feel that battery energy storage is especially effective in combination with solar energy. The reasoning is this:

Solar energy storage mitigates the intermittent nature of renewable power and guarantees a steady supply of electricity.

Generally speaking, batteries for a home or business solar energy system include a built-in inverter to change the DC current generated by solar panels into the AC current needed to power appliances or equipment.

Consequently, a solar battery storage works with an energy management systemthat manages the charge and discharge cycles based on real-time needs and availability.

Fundamentals of Battery Energy Storage System (BESS) Course by Tonex

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.
