At the same time, the analysis makes it clear that the economic efficiency of a large-scale battery storage system cannot be assessed in isolation. The decisive factor is the interplay of technical parameters (usable capacity, efficiency, degradation and service life) with commercial factors such as investment expenditure, price trends and the chosen marketing strategy.
Based on this, the whitepaper shows how a robust investment case should be structured. In addition to key financial figures, risks should also be taken into account as well as regulatory and strategic framework conditions. Successful grid connection, supply chain dependencies and geopolitical influences have a direct impact on profitability and should be systematically analysed in different scenarios.
For investors, the question of technology selection also arises. Lithium-ion, zinc-bromide and sodium-ion storage systems each offer specific advantages and risk profiles. Which technology is suitable depends on the specific application and the strategic objectives of the investor.
The whitepaper concludes that investment decisions for large-scale battery storage systems are only future-proof if they are made holistically. Those who bring together technical, economic and strategic requirements and consistently take individual project parameters into account create the basis for sustainable returns and utilise the opportunities of a rapidly changing electricity market.
