Technical FAQs 4

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:

What is a battery energy storage system (BESS)?

Battery Energy Storage Systems (BESS) are pivotal technologies for sustainable and efficient energy solutions.

Should a battery energy storage system be installed for customer self-use?

Remarks: If a Battery Energy Storage System (BESS) will be installed for customer self-use, it should be ensured the BESS does not have capability to export power to or back energize the distribution network connected in parallel with the main grid.

How do I connect a Bess to a power supply?

The incoming cable shall be sized based on maximum allowable input current to the BESS. Connect the BESS from utility supply mains. With small required charging current of BESS, the remaining supply can be used for other relatively steady loads.
