BESS Consulting FAQs
What information do you need to start a BESS feasibility study?
Typically your load profile or electricity bills, site details, grid connection information and the intended application (peak shaving, backup, hybrid or utility-scale). We guide you on anything missing.
Can you help choose between Li-ion, VRFB and hybrid technologies?
Yes. Technology selection is part of our scope, comparing options against your application, site, safety and commercial requirements.
Do you prepare documents for tenders and vendor evaluation?
Yes. We prepare technical specifications, scope of work, evaluation criteria, BoM and RFI/RFQ/tender documents, and can review vendor quotations.
Can BESS be combined with an existing or planned solar plant?
Yes. We model and design hybrid solar + storage systems using tools such as HOMER and PVsyst.
