The energy transition is fundamentally reshaping the power system. Large-scale battery storage systems play a central role in this transformation: they balance fluctuations, stabilise the grid and generate returns from multiple sources. What was long considered a technical niche topic is increasingly developing into an asset class in its own right – with concrete access routes for professional investors.
Electricity demand is growing significantly faster than overall energy consumption through 2030. At the same time, conventional capacity is disappearing from the grid: nuclear power is being reduced, while coal-fired power plants are being phased out. Renewable energy sources are taking on an ever-larger share, but they do not generate electricity consistently. This is precisely what creates a structural need for storage solutions.
Large-scale battery storage systems are therefore not merely a topic for the next market cycle, but a response to a fundamental transformation of the energy system. The fact that infrastructure ranks among the most sought-after asset classes in 2025–2026, with many investors increasing their allocations, fits this picture. Investors entering the market today are not reacting to a scenario, but to a development that is already a regulatory and economic reality.

Multiple Revenue Streams: The Principle of Revenue Stacking
A large-scale battery storage system is not a passive asset. It generates revenue on several levels simultaneously – depending on the market, this can result in annual revenues of EUR 40,000 to 180,000 per MW. This combination of market-based and contractual cash flows gives BESS investments a genuine infrastructure character: real assets, a useful life of 15+ years and low correlation with equity and bond markets.
- Energy arbitrage approx. 58%
Capturing day-night price spreads. Day-ahead and intraday trading. Between 1 and 4 cycles per day possible. - Balancing energy SRL/PRL approx. 30%
Primary and secondary control reserve: contract-based, predictable revenues. Frequency reserve capacity provided to grid operators. - Contractual cash flows approx. 12%
Direct agreements with grid operators and utilities.
Webinar Replay: Battery Storage for Professional Investors
In the webinar held on 7 May 2026, Agnes Rivas from Picard Angst and Bernhard Glück from MW Storage explain why battery storage is increasingly being perceived as an asset class in its own right. The discussion focuses on the economic function of BESS, the revenue logic and access via the MW Storage Fund for professional investors.
Webinar Replay: Battery Storage as an Infrastructure Topic for Pension Funds
The webinar held on 6 May 2026 is aimed specifically at Swiss pension funds. Agnes Rivas and Yonten Wagma explain how battery storage can be classified as an infrastructure topic from a regulatory perspective, the role played by BVV 2 compliance and which solution approaches are available through the VALYOU Investment Foundation.
Battery storage is not a bet on the future – it is operational infrastructure that is already generating returns today.
Offers
Depending on the investor profile, two different access routes are available.
MW Storage Fund
The MW Storage Fund is aimed at professional investors. It invests in BESS projects in Switzerland, Germany and Finland, has a track record dating back to 2019 and is structured as an open-end / evergreen vehicle in EUR. For investors seeking direct and scalable access to this market segment, the fund offers a clear and structured approach.
VALYOU Investment Foundation
The VALYOU Investment Foundation is aimed at Swiss pension funds. It is BVV 2-compliant, authorised by OAK BV, structured in CHF and does not require capital commitments. It invests in BESS projects and offers access specifically tailored to the regulatory and operational requirements of occupational pension institutions.
Battery storage is no longer merely a technical infrastructure topic, but an investable market segment with concrete access routes. “With a cumulative net return of 253% at the Ingenbohl site from January 2021 to December 2025 and first place in the KGAST ranking, the VALYOU Investment Foundation demonstrates the potential of this area.” The MW Storage Fund complements this picture with operational projects in three countries and a track record dating back to 2019.
Picard Angst supports investors in accessing this asset class – with regulatory clarity, experienced partners and an assessment tailored to the respective portfolio.
