BESS Revenue Benchmarks
Comparison of European BESS revenue benchmarks.

Executive introduction
Why European BESS benchmarks differentiate?
Published BESS revenue benchmarks for the same market and the same asset duration significantly differ. The divergence is almost never a view on price levels — it is a set of methodological choices sitting underneath the headline figure. For an investment committee, the useful question is not which benchmark is highest, but which assumption set matches the asset, the route to market and the financing structure in front of you.
1.0 vs 1.5–2.0 cycles/day
Cycling intensity
A benchmark assuming 1.0 cycles/day and one assuming 1.5–2.0 cycles/day describe the same asset with radically different throughput and revenue potential. Resulting degradation is not taking into consideration.
94% vs 100%
System availability
Modelled cases often assume 98–100% availability. Realised fleets sit below 100% once outages, grid curtailment and augmentation downtime are included. The timing of unavailability is the key driver for the revenue implications.
Capture rate
Foresight assumption
Perfect-foresight optimisation sets an unreachable upper bound. Real trading desks operate on rolling forecasts and with increasing asset sizes the effect becomes more significant.
90% vs 100%
Usable SoC
Min/Max SoC limits determine range within the BESS can operate. Benchmarks vary between 100% usable SoC and 90% (min of 5% and max of 95%).
