Technical FAQs 4

How much energy does a Bess site hold?

A BESS site with a capacity of 200 MW/800 MWh holds a substantial amount of stored energy. This is loadshedding? equivalent to a single unit at Medupi Power Station running for an hour.

What is Bess energy storage & how does it work?

BESS stores excess energy during high generation periods and releases it during low renewable output, ensuring continuous power supply. Integrating energy storage with renewables aids in reducing greenhouse gas emissions and promotes sustainable energy practices.

Do I need backup power for a Bess auxiliary load?

For certain projects, backup power must be provided for the BESS auxiliary load as required by the BESS supplier or fire codes. Some BESS suppliers mandate uninterrupted power to maintain the operation of thermal management systems, ensuring battery temperatures remain within desired limits to minimize degradation.

Who is responsible for the electricity costs associated with Bess auxiliary loads?

Project owners are also responsible for the electricity costs associated with the BESS auxiliary load during operation. The electricity cost for auxiliary loads depends on the energy consumption (kWh) and the pricing structure set by independent system operators or utilities. For example:
