Reality anchor: real asset vs. potential
The ceiling below is the THEORETICAL Day-Ahead arbitrage revenue with a perfect forecast (zone GB, current day, via our dispatch engine). A real asset never reaches this ceiling: imperfect forecast, efficiency, cycling. The quantified reference of a REAL asset is our GERMAN 1.5 MW battery (GDPR-anonymised) — it is a German example, not a British asset.
Ceilings computed via core.dispatch_day on real Day-Ahead prices (zone GB). The delta between potential and realised is exactly the layer of transparency that Stromfee builds.
Who earns what — and where?
British market roles, clearly 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.
System operator (NESO) / exchanges
Negative prices reflect overproduction; the market clears the surplus, the system operator handles grid balance. No trading profit.
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.
