How do I choose a Bess supplier?

Jeff Zwijack outlines key factors in selecting BESS suppliers, focusing on quality, warranties, and strategic partnerships for long-term success.

What is a Bess product warranty?

Where the supplier is also the BESS manufacturer, the product warranties provided are key. For BESS projects, battery cell degradation is inevitable, but a comprehensive product warranty helps ensure that this can be modelled by the developer as part of their return on investment calculation and be priced for.

Do Bess developers need to review their procurement plans?

For BESS developers, these tariff increases will necessitate a review of their procurement plans for their projects to either secure alternative supplies of batteries and construction materials or otherwise ameliorate the impact of the increases.

Does Bess have a quality control process?

Analysis of BESS manufacturing issues and defects conducted by Clean Energy Associates reveals that about 30% of faults originate during battery cell manufacture. System-level defects accounted for almost 50% of our findings. Compared to the cell-manufacturing process, BESS integration has fewer quality control procedures.

Why do you need a Bess RFP?

A well-structured BESS RFP ensures you receive comprehensive, competitive, and technically compliant proposals in time. By defining clear technical specifications, vendor qualifications, and pricing expectations, you can select the best energy storage solution for your needs.

Should Bess warranty terms be included in a separate document?

Many suppliers try to include the BESS warranty terms in a separate document (i.e. outside of the main supply agreement). It is also not uncommon for the supplier to be a different entity to the entity that will provide services in connection with the BESS under an LTSA. Both approaches are problematic for different reasons.
