Pricing
Bessify system pricing
Safety shapes the Bessify system. Making storage a sound investment shapes its economics.
Bessify designs and builds a complete AC-connected energy storage system in Estonia, including its own PCS, battery management and control firmware. We publish indicative prices so you can assess that engineering against the economics of your project.
Our introductory pricing reflects our position as a new manufacturer establishing its first customer relationships. The system retains the safety architecture and engineering described throughout this website.

See our Privacy notice for how we handle enquiries.
An indicative equipment estimate for a single system, not a binding quotation. Project pricing is agreed individually. No payment or reservation is made here.
System certification and first deliveries are targeted for Q3 2027, subject to successful testing and certification. Preferred dates are an enquiry, not a delivery commitment.
Where the economics come from
Engineering the whole system gives us control of cost
We design the battery architecture, PCS, sensing and controls together. Our single-module Energy architecture reduces duplicated electronics. Where available components did not meet our technical requirements or offer a competitive price, we developed our own.
Safety and performance requirements guided component selection. Where meeting those requirements cost more, we accepted that cost. We pursued savings through system design, manufacturing and reducing duplicated components.
Safety in the system price
TRPPS 1 active propagation prevention and TRPPS 2 independent water-deluge and progressive-flooding protection are part of the system design.
Ownership through life
Bessify owns its PCS and control firmware. The engineering behind the system remains available to maintain, support and develop it throughout its life.
A clear basis for comparison
A complete AC system. A defined supply scope
The price covers the integrated Bessify system at the factory gate. When comparing proposals, compare usable AC energy, included equipment and delivery scope on the same basis.
€175per usable AC kWh · 3 MW / 2 h
€158per usable AC kWh · 1.5 MW / 4 h
€150per usable AC kWh · 750 kW / 8 h
The same 6 MWh of net usable AC energy in every configuration, so the unit price falls as the power configuration reduces. Indicative factory-gate estimates.

| Item | Price basis |
|---|---|
| Energy | 6 MWh net usable AC energy per system at its 690 V output terminals, at beginning of life. Internal conversion losses and auxiliary consumption are accounted for. Final operating windows and verified performance follow testing. |
| Power and duration | 3 MW / 2 h, 1.5 MW / 4 h or 750 kW / 8 h, using the same Energy platform. |
| Included equipment | Energy, Power and Thermal compartments; Bessify PCS, battery management, sensing, Core control firmware and system safety functions. |
| AC interface | 690 V, three-phase, 50/60 Hz. Project-specific equipment beyond the system terminals must be identified separately in the project scope. |
| Factory-gate terms | Jüri, Estonia. Prices in euro. Delivery, installation, site works, grid connection, commissioning, applicable taxes and project-specific regulatory charges are excluded. |
| Support and warranty | Support charges, equipment warranty conditions and any capacity agreement are set out separately in the commercial proposal. Core must remain in service under the current equipment warranty offer. |
| Optional services | Control for multi-system sites and Intelligence services are scoped and priced separately. |
| Quotation | Final price, validity, payment terms and delivery schedule are confirmed for each project, taking account of configuration, component pricing and commercial terms. |
