BESS FAQs

Information on Battery Energy Storage Systems (BESS)

1. What is a Battery Energy Storage System (BESS)?

A Battery Energy Storage System stores electricity for later use, often sourced from renewable technologies such as solar and wind. It enables surplus energy to be retained and discharged during periods of high demand, helping to balance supply and demand across the grid.

2. How does BESS support the transition to renewable energy?

BESS facilitates the integration of intermittent renewable sources by stabilising grid fluctuations and reducing price volatility. It ensures that energy generated from renewables can be used efficiently, regardless of weather conditions, supporting the UK’s net-zero carbon goals.

3. What are the benefits of using BESS?

Battery storage offers multiple advantages, including reduced energy costs, enhanced grid resilience, improved energy security and lower carbon emissions. It also supports peak shaving, load shifting and backup power, while enabling businesses to sell stored energy or use it during peak pricing periods.

4. What sectors benefit most from BESS?

BESS is valuable across various sectors, including manufacturing, data centres, defence, telecommunications and remote facilities. It supports energy resilience, uninterrupted power supply and compliance with environmental regulations.
