About BESS Manufacturers
BESS Manufacturers is a directory of battery energy storage equipment manufacturers. We built it because procurement teams, project developers, and engineers in the energy storage industry deserve a single, reliable place to compare suppliers.
What we do
We maintain detailed profiles for 76 manufacturers across battery cells, DC blocks, PCS, AC blocks, and plant controls. Each profile includes technical specifications, product datasheets, certifications, financial data, and ESG filings — all sourced from public filings and official documentation.
We also publish in-depth analysis of manufacturer comparisons and industry developments, and maintain a technical glossary of energy storage industry terms.
The team
BESS Manufacturers is built and maintained by a small team of energy storage professionals based in Europe. We work in the BESS industry ourselves and built this directory to solve a problem we had first-hand: fragmented, outdated, and hard-to-find manufacturer information.
Our editorial content is written by the team — manufacturer profiles are sourced from public filings and official documentation, not paid submissions.
Our principles
Facts only
Every data point is sourced from public filings, official datasheets, or company disclosures. We don't editorialize or create rankings.
Free to use
The entire directory is free to use. No login required, no gated content.
Built by industry
We work in the BESS industry ourselves. The directory exists because we needed it — and so does the rest of the market.
