Record-high Balancing Mechanism revenues in August 2024
Battery energy storage revenues in Great Britain rose by 42% in August, earning £56k/MW/year. This almost tied the high for 2024 set in April. August featured an additional 49 hours of negative power prices, as high wind generation met low demand.
In August, revenues from wholesale trading, frequency response, and the Balancing Mechanism all increased. The largest increase came from the Balancing Mechanism which rose to £12k/MW/year, beating the previous record set in April 2024 by £2.5k/MW/year.
