The installation of a BESS is carried out in four phases - We offer the first phase free of charge for companies with a strong business case
Accurate calculations of installation costs and revenue streams provide a clear overview of the potential benefits
If the company has access to renewable energy, a BESS solution is often a strong and profitable long-term investment
Read our White Paper and gain key insights into all aspects of BESS investments in the market
A BESS investment should always be based on a comprehensive business case that reflects both costs, savings, and revenue over the expected lifetime of the system. It is crucial that the business case is built on realistic assumptions and does not rely on maximum or theoretical best-case scenarios.
The business case should include all relevant CAPEX and OPEX elements, including hardware investment, service, software, warranties, and battery degradation. On the revenue side, both stable savings and more variable income streams must be incorporated, with a clear distinction between secure and uncertain elements.
In addition, sensitivity analyses should be conducted to show how changes in electricity prices, tariffs, usage patterns, or battery utilisation affect returns.
A realistic business case may not necessarily look the most attractive on paper, but it provides the strongest foundation for a decision that remains robust over time.
SolarFuture Has Expertise in BESS
A BESS system is not just a battery — it is an asset that must perform technically, economically, and commercially for many years. Value is only realised when dimensioning, operation, and market integration work seamlessly together.
This is where SolarFuture differentiates itself by delivering tailored BESS solutions that strengthen energy security, reduce energy costs, and support companies’ green transition. We work with standardised solutions, but always tailor them to the individual company’s consumption profile, grid conditions, and commercial objectives.
ValueStorage – SolarFuture’s BESS Concept
ValueStorage™ is SolarFuture’s proven BESS concept, developed with documented financial performance and designed for industrial companies seeking lower energy costs, improved supply security, and a stronger sustainability profile — without tying up unnecessary liquidity.
SolarFuture acts as the coordinating partner, ensuring that all components function in harmony — technically, regulatory-wise, and financially.
No two companies are alike, and there is no standard BESS solution. The purpose of a pre-analysis is to clarify the company’s specific technical, operational, and market conditions before dimensioning and investment decisions are made.
As a minimum, the analysis should include historical electricity consumption, effect profiles, grid connection conditions, infrastructure, and any potential on-site generation. At the same time, physical site conditions such as space availability, access conditions, fire safety, and existing installations are assessed. These factors have a direct impact on both system design and cost.
The pre-analysis also helps identify potential constraints at an early stage. These may include grid limitations, lack of available capacity, or conditions that restrict certain use cases. The earlier these are identified, the greater the likelihood that the final solution will be both technically and economically viable.
SolarFuture acts as EPC across all phases
SolarFuture serves as EPC for all phases, with full responsibility throughout the process. We act as system integrator and accountable partner, maintaining full oversight of both the technical solution and market integration. This includes:
We document performance
SolarFuture has strong references from large energy consumers and solar power plants. We manage fire and safety design, FAT/SAT testing (Factory or Site Acceptance Tests), and acceptance testing, and we ensure a comprehensive lifecycle plan for the battery system.
We do not promise simplified standard solutions or theoretical maximum cases. Instead, we deliver robust decision-making foundations and BESS solutions with documented performance and real economic value.
The result is a measurable, reliable, and future-proof BESS solution.
A concrete business case example can illustrate how different elements interact in practice. Typically, the case demonstrates how a BESS system is dimensioned based on the company’s power demand and how value is distributed between cost savings and revenue streams.
The example should clearly outline:
which use cases are prioritised,
which assumptions form the basis of the calculations, and
how payback period and returns develop over time.
The purpose of the example is not to present a universal answer, but to demonstrate the structure of the decision-making framework. This makes it easier for companies to relate the figures to their own conditions and assess which parameters are most critical in their specific situation.
A BESS investment is only attractive if the numbers add up. We assess this together using a cash flow model that consolidates CAPEX and OPEX against savings and revenues, clearly showing when the investment becomes profitable.
