Capital
Think economically about battery storage.
wattss Capital makes battery storage financeable and provides investors with access to a growing pipeline of BESS projects in Europe.
Battery storage requires more than good technology – it requires the right financial structures. wattss Capital combines project expertise with capital market know-how: as a financing partner for companies and as an investment platform for investors, family offices, and investment foundations.
Financing Solutions
The right financing structure often determines whether a battery storage project is realized – or not. wattss Capital structures solutions that fit your situation: with predictable installments, minimal capital commitment, and a partner who knows the project from start to finish.
Financial Leasing
Implement modern battery storage without high upfront investment. Our financial leasing enables companies and public institutions to acquire a battery storage system with predictable leasing installments and minimal capital commitment. After the leasing period expires, the storage system typically transfers to your ownership.
Together with leading partner banks in Switzerland and the EU, we offer flexible terms and transparent conditions: structured from a single source and tailored to your needs.
