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.

01
Gross revenue
Balancing energy (FCR, aFRR, mFRR as a supplementary channel) + spot market arbitrage. Fully automated optimization via CUBE EfficiencyUnit.
02
OPEX deduction
O&M, Marketing, IT, Monitoring — each item disclosed individually. No flat-rate margin.
03
Net sales
Remaining profit after all operating expenses — basis for the division between you and CUBE CONCEPTS.
04
Profit Sharing — project-specific, open-book
Agreed before signing. All assumptions to be disclosed.

Individual billing: No pool model — your system will be billed separately. You will see exactly how much your battery storage system has generated.
Open-book: Transparency within the business relationship — no public cost presentation.
Example Calculation — 1 MW Battery Storage
FTM Gross Revenue €200,000–300,000
OPEX deduction -€55,000
Net sales €145,000–€245,000
Your share (25–%) €36,000–€61,000/year

Risk distribution

Risk allocation in Contracting — contractually defined

When it comes to the Contracting model, the answer is clear: CUBE CONCEPTS.

CUBE CONCEPTS wearsYou provide
Total Investment Risk (CAPEX)Area at the location
Technical operational riskNetwork connection capacity
Failure risk of the storage facilityLoad cycle data for design
Component Selection and Supplier RiskOperating permit (coordination by CUBE)
Operating costs (O&M, insurance)
FTM Marketing Risk
Weaker market phases reduce the shared net revenue—but they don't create costs for the customer. This is structurally different from purchasing, where market risk lies entirely internally.
Common Objections

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.
