- Wishaw outperformed peers - by maximizing Balancing Mechanism imports instead of relying on Dynamic Regulation High.
- Batteries cycled 15% less in September as lower wholesale spreads reduced the incentive to cycle frequently, weakening Dynamic Containment revenues.

Introduction
In September 2024, battery energy storage systems in Great Britain earned average revenues of £37.5k/MW (annualized). This was 20% lower than in August - despite September 10th being the single highest-earning day of 2024 so far for batteries. However, one battery bucked this trend and earned higher revenues in September than it did in August - by maximizing its Balancing Mechanism availability.
