Stored energy only pays when it is traded against the market. We compute the Decke — the perfect-foresight day-ahead ceiling every ≥1 MW battery could reach — and benchmark real assets against it. Live across 34 markets, independent of vendor and trader.
The instinct never changed: follow the price. The scale did.
Shelly & Loxone spot-price switching. We taught loads — heat pumps, boilers, pumps — to run when power is cheapest. The idea, proven in the home.
BESS arbitrage power-trading optimization. The same instinct at industrial scale: batteries trading the day-ahead and intraday markets, optimized to the perfect-foresight ceiling.
Built on our arbitrage trading heritage (Fariah) — a perfect-foresight dispatch optimizer that prices every market, every day. Independent, no trading book of our own.
Real day-ahead data, refreshed daily. The Decke a 1 MW · 2 h battery could have captured. Click a market for the full radar.
No hardware to sell, no trading book. We optimize and benchmark — vendor- and trader-neutral.
Every ≥1 MW battery from public registries, real capacities, real prices — not a model assumption.
Day-ahead arbitrage across Europe and worldwide. The same neutral ceiling, every market, every day.
We compute the perfect-foresight arbitrage ceiling for any ≥1 MW battery — independent, from public data — and show the gap to reality.
