Reality anchor: real asset vs. potential
The ceiling below is the THEORETICAL Day-Ahead arbitrage revenue under a perfect forecast (zone IE_SEM, current day, via our dispatch engine). A real asset never reaches this ceiling: imperfect forecast, round-trip efficiency, cycling. The quantified reference of a REAL asset is our GERMAN 1.5 MW battery (GDPR-anonymised) — it is a German example, not an Irish asset.
Ceilings computed via core.dispatch_day on real Day-Ahead prices (zone IE_SEM). The delta between potential and realised is exactly the layer of transparency Stromfee builds.
Who earns what — and where?
Irish market roles, cleanly separated.
Balancing responsible / trader
Reads here when charging is worthwhile: at negative prices, you are paid to charge.
Asset operator
More negative intervals = more economically usable cycles for the battery.
Investor
A rising share of negative intervals widens the business case — without extrapolating from a single month.
Grid operator (EirGrid) / SEMOpx
Negative prices reflect over-production; the market clears the surplus, the transmission operator keeps the grid balanced. No trading profit.
Quality data for imbalance settlement
The potential shown here becomes real revenue only if it can be settled cleanly: revenue-quality metering data and the market settlements decide what is billable. Stromfee builds exactly this layer of transparency.
