Contracting Battery Storage — Revenue Without Capital Investment
Invest €0. 25% of the proceeds — for you.
Most providers sell hardware or electricity. CUBE CONCEPTS builds the system behind it.
How BESS Contracting works
The basic logic: You have the grid connection and the location. CUBE CONCEPTS has the capital, technology, and operational experience.
The Contracting model: CUBE CONCEPTS builds and operates the facility at its own expense. The customer shares 25% of the net market proceeds—with no upfront investment. Transfer of ownership is optional (purchase option).
Contracting or purchase — which option is right for you?
How the energy storage generates revenue
The battery storage system unlocks two independent revenue streams simultaneously. The multi-market optimization automatically decides which market is currently the most profitable.
Profit Sharing — How Contracting Revenues Are Divided
Four stages, fully disclosed — before signing.
Risk allocation in Contracting — contractually defined
When it comes to the Contracting model, the answer is clear: CUBE CONCEPTS.
| CUBE CONCEPTS wears | You provide |
|---|---|
| Total Investment Risk (CAPEX) | Area at the location |
| Technical operational risk | Network connection capacity |
| Failure risk of the storage facility | Load cycle data for design |
| Component Selection and Supplier Risk | Operating permit (coordination by CUBE) |
| Operating costs (O&M, insurance) | — |
| FTM Marketing Risk | — |
Common Objections to the Contracting Model — Direct Responses
„€0 in personal investment and still €25 in revenue—what’s the catch?”
There are no hidden fees. CUBE CONCEPTS only earns a fee when the investment performs—75% of the net market proceeds. No performance, no fee. That is how our interests are aligned.
„How can I check the billed revenue — I don't have my own access to the trading data?”
Open-Book: monthly itemized billing for your location — not pooled. Each revenue channel, each OPEX item, each billing period visible. Agreed upon before your signature.
„What if the grid energy markets collapse - will we still have costs?”
No. Your risk is structurally zero: no CAPEX, no OPEX, no guaranteed payments. Weaker market phases reduce the shared revenue — but do not generate costs for you.

What the Contracting model can do for your business
Battery storage in return for industrial electricity prices
Starting in 2026, KUEBLL companies will be able to apply for a government-subsidized industrial electricity rate of approximately 5 cents per kWh for up to 50% of their electricity consumption.
At least 50% of the aid disbursed must be used for climate protection measures. Battery storage systems qualify—Contracting counts as a qualifying measure. (CISAF para. 121)
20 years of network charge exemption for systems with commissioning until August 4, 2029. Not extendable, not retroactively acquirable.
