OSLO, NORWAY — September 8, 2026 — Electrification technology provider Volue has released new research demonstrating that two European battery energy storage projects built to identical technical specifications and costs can yield significantly different financial returns based on trading execution.
In its white paper, From Asset to Algorithm, Volue argues that the European battery storage market has transitioned into a second operational phase. Over the past decade, competition centered primarily on hardware costs per kilowatt-hour, cell chemistry, and warranty parameters. As hardware costs have converged, Volue asserts that physical specs no longer serve as the primary differentiator for asset profitability.
Instead, project returns are determined by three core factors: grid access, market access and ongoing trading strategy. Of these, trading performance is the only variable that can be improved year after year.
Shifting Revenue Channels and Market Compression
The report highlights a structural transition in battery revenue streams across Europe. Early storage business cases relied heavily on frequency-response and ancillary service markets designed for grid stabilization. However, as additional storage capacity enters service, returns in these markets are thinning.
Volue projects that value creation will continue migrating toward wholesale trading—specifically continuous intraday markets. The paper cautions that increased asset participation will eventually compress margins in intraday markets as well.
At the same time, operational timescales across European power markets are accelerating:
- Quarter-Hourly Settlement: Europe’s shift to 15-minute day-ahead trading intervals has multiplied daily trade decisions.
- Complex Ancillary Integration: Managing multiple market participation models leaves shorter timeframes for execution, expanding revenue opportunities while narrowing the margin for human error.
Algorithmic Integration and Asset Degradation Management
Trading battery storage requires balancing single-asset capacity across interacting revenue channels while factoring in physical degradation costs per cycle. Volue concludes that forecasting, portfolio optimization, and trade execution can no longer operate as siloed functions, as errors in initial forecasting compound through to final execution.
Helmut Spindler, General Manager Trading & Optimisation at Volue, stated:
“Europe has built a remarkable amount of storage in a short space of time, and the next phase is about getting the most out of it. Trading and the operation of assets continue to become more complex, all of which makes operating performance a much bigger part of the return.“
He added:
“From Asset to Algorithm puts evidence behind the fact that the gap is now created in the trading room rather than at the point of procurement. That matters for anyone financing, building or operating storage in Europe, because it changes where value is created and how performance should be measured. We have published the findings openly because the market as a whole benefits from a clearer, evidence-based view of where battery revenue is heading.“
The findings are intended to inform battery developers, investors, asset managers and traders seeking to maximise returns from European BESS portfolios.
