Municipal utilities & suppliers
Gets: Neutral economics, grid operator deadlines, comparable quotes — without a vendor lens.
Contributes: Project plans and experience from their own grid area.
Start calculating →The ecosystem
Give to get.
BESS-Market is neither a directory nor a lead broker. It is a loop: every participant contributes one thing they already have — and receives something they cannot get alone.
The loop
- 01
Tools
Developers and utilities calculate, check deadlines and plan — free of charge.
- 02
Project intent
Concrete projects emerge: size, region, timeline, needs.
- 03
Partners
Manufacturers, EPCs, optimisers and capital providers want to reach these projects.
- 04
Data
In return they contribute anonymised market data — the tools get more accurate.
More accurate tools attract more projects. More projects make the platform more valuable for partners. The flywheel turns faster every month.
Who we are built for
Mid-market · 1–30 MW
Municipal utilities, regional developers and industrial companies. Too small for expensive analyst houses, too big to do on the side. This is our focus — about two thirds of municipal storage projects are below 10 MW.
Large projects · above 30 MW
Utility-scale storage, connection at 110 kV and above, structured offtake and institutional finance. The same tools, set up for the demands of large projects.

Our rules
Trust is the actual product. That is why these rules are public here — not in an internal memo.
- 01
Rankings are not for sale
No provider appears preferred in the configurator, search or benchmarks because it pays. Paid visibility exists only visibly separated and labelled as such.
- 02
No lead selling
Your contact details go to third parties only with your explicit consent — case by case, never in bulk. Calculating stays anonymous. If you want offers, you say so yourself.
- 03
Aggregated data only
What we publish as a benchmark is always aggregated and anonymised, with the method disclosed. At least five contributors per value — otherwise no value.
- 04
No exclusivity for large partners
No manufacturer or optimiser buys a category. Only exception: whoever contributes data first is named as the sole source for a limited time.
- 05
No trading on our own account
We do not buy projects, give offtake guarantees or pre-finance anything. We broker — and stay independent.
Become a data or expert partner
No partner conversation with us starts with an invoice. You contribute one kind of data or your expertise — we turn it into a tool or a benchmark and name you as the source.
