Do Bess products need an external power supply?

Most BESS products on the market require an external power supply circuit for their auxiliary loads, although some have built-in circuits and do not need an external supply.

Does Bess require uninterrupted power?

Some BESS suppliers mandate uninterrupted power to maintain the operation of thermal management systems, ensuring battery temperatures remain within desired limits to minimize degradation. BESS fire safety standards, such as NFPA 855, outline minimum requirements for backup power for fire safety systems.

Does Colombia have a power purchase agreement for hybrid solar & Bess projects?

As of now, Colombia’s reliability charge (Cargo por Confiabilidad) has encouraged hybrid solar + BESS projects to progress. Large energy companies have expressed that there are no Power Purchasing Agreements (PPAs) available specifically for stand-alone storage projects, making it harder to finance those projects.

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.

What if a Bess product does not meet backup power requirements?

If a BESS product cannot meet these backup power requirements as mandated by the code or the Authority Having Jurisdiction (AHJ), an external backup power source needs to be provided. Options for backup power include local distribution network feeders (if available with sufficient kVA rating) or backup generators.
