Battery Arbitrage Opportunity — Week 13, 2026

Germany experienced another high-value battery-arbitrage week as wholesale electricity prices moved from slightly negative levels to almost €300/MWh. EUnix Market Intelligence identified a maximum daily arbitrage spread of €264.03/MWh and 34 strong opportunity hours. An illustrative 1 MW / 1 MWh battery simulation produced €233 in gross weekly arbitrage revenue, showing that strong market spreads do not always translate into equally high realised returns.
