BESS –  Battery Energy Storage Systems

What is a  BESS?

A battery storage system is made of devices that create energy from renewable solutions like solar and wind. The energy is then stored in high-performing lithium batteries in order to be released to when power is most needed. 

How does a BESS work?

A Battery storage system uses several components to work and each system has its own algorithm with computerized control systems. This is what allows the energy to travel from its renewable source to the high quality batteries used. 

What is the life expectancy of a BESS battery?

The average life expectancy of these batteries is 8 to 12 years 

How long does it take to build a BESS?

The size of the BESS determines the construction period, but this can take between 6 to 12 months. 

Different types of battery energy storage

Although lithium-ion batteries are the preferred product when it comes to to battery storage systems, there are other types that can be used for this such as:

  • Lead acid batteries
  • Lead carbon batteries
  • Flow batteries
  • Sodium-sulfur (NaS) batteries
  • Solid state batteries 

4 benefits of BESS 

  • Backup power: Whether you use BESS as your sole power source or rely on it as a backup. Having enough backup power is a smart decision if faced with a power outage. 

  • Less dependence on the grid: In some areas of the UK the national grid is not as efficient and more prone to blackouts.

  • Reduce carbon footprint: Collecting renewable energy through BESS reduces greenhouse gas emissions and minimizes pollution. 

  • Long term cost savings: BEES are not cheap to install, but in the long run they pay for themselves. They ultimately make big savings on energy bills and add value to a property.
