GB batteries saved consumers £188 million since December 2024
Modo Energy quantifies the consumer benefit of Great Britain's growing BESS fleet over a five-month window.

GB battery storage has saved consumers £188 million since December 2024, according to Modo Energy. The number spans roughly five months of fleet operation and captures value across wholesale arbitrage and system balancing: two of the primary revenue streams for GB BESS assets.
Modo Energy does not break the £188 million figure by individual revenue stream in the headline data, so the split between wholesale and ancillary services contributions is not confirmed here. What the aggregate does show is that the consumer saving is material at the system level, not confined to a single grid constraint zone or service.
The GB BESS pipeline has grown sharply over the same period, meaning the per-unit saving rate and total installed capacity are both moving targets. Analysts tracking capture prices or aFRR revenues should note that Modo's £188 million is a gross consumer-benefit figure, not a revenue or margin number for asset owners.
