D6 · All markets side by side

All of a battery's revenue sources seen together: energy continuously, capacity in steps — alternatives, not additive.

D6 · revenue transparency

All markets side by side

All revenue sources of the same battery seen together. Energy products move continuously; capacity products advance in hourly steps. The key: they are ALTERNATIVES — optimising means choosing the right market each hour, not summing them all.

Energy (Day-Ahead / intraday)

Moves continuously — every hour has a price; the battery follows the charge/discharge spread.

Reserves (FCR / aFRR / mFRR)

In steps: capacity is reserved hour by hour, paid on availability.

Capacity

Guaranteed availability at peak — long-term remuneration, not tied to the hourly price.

And then?

Real revenue depends on quality metering data for imbalance settlement — that is the layer Stromfee builds.

Quality data for imbalance settlement

The potential shown here only becomes real revenue if it can be settled cleanly: revenue-quality metering data and market settlement decide what is billable. Stromfee builds exactly this layer of transparency.
