Battery storage arbitrage margin for a day on the German-Luxembourg day-ahead ma
Battery storage arbitrage margin for a day on the German-Luxembourg day-ahead market (EPEX SPOT DE-LU hourly prices): for a 1, 2 or 4 hour battery, the cheapest charging hours and the most expensive discharging hours, the daily price spread and the gross margin per MW of power after round-trip losses (default 88%). One full cycle per day, perfect foresight, no grid fees or degradation: an upper-bound screening number, not a trading result.
