Battery storage systems are becoming a central component of the European energy transition. With the growing market and an increasing number of project developments, the financial viability of storage projects is becoming a crucial question for developers, investors and lenders. The financial consulting boutique Capcora and the marketing specialist suena energy have jointly written the white paper "Bankability by Design: Financing and Marketing Models for Battery Storage Projects". The publication analyses how banks and other debt capital providers evaluate battery storage projects and what influence marketing strategies, risk distribution and financing structures have on the bankability of a project.
The white paper combines the perspectives of project financing and marketing and examines the factors that determine the financial viability of battery storage projects: the reliability of future revenues, the contractual design of projects and the handling of price risks on the market. The analysis shows that financing requirements must be taken into account at an early stage of the project and have a significant impact on the design of storage projects.
A key finding of the white paper is that identical battery storage systems can lead to significantly different financing results depending on their commercial design. A case study shows how different forms of revenue hedging affect the capital requirements, the leverage ratio and the financial viability of the same storage project.
"The market for battery storage systems is developing into an asset class in its own right. For banks and other investors, the focus is not on the theoretical revenue potential, but on the question of how reliable and plannable a project's future cash flows are. This is where marketing strategy and risk distribution become more important," says Alexander Kuhn, Managing Partner at Capcora.
"Battery storage systems are increasingly seen as critical infrastructure for the energy transition. However, their financing is not determined solely by the technology, but by the quality of the project structure. Those who integrate marketing models into project development at an early stage create the basis for financially viable and economically successful storage projects," says Lennard Wilkening, CEO and co-founder of suena energy.
The white paper is aimed at project developers, investors and financing partners. It shows which factors are decisive in financing decisions and how battery storage projects can be structured in such a way that they can be financed on the capital market.
