Quantum Data Energy (MAST ) has delivered record electricity generation and revenues from its 100% owned Pyebridge 8.1 MW flexible generation power asset over the first eleven months of 2025, with both production and sales significantly ahead of the prior year. The performance underscores the growing demand for flexible power generation as intermittent renewable supply increases across the UK grid.
In November 2025, Pyebridge maintained strong monthly output and sales of around 1.3 Gigawatt hours of electricity, matching October's record performance. Over the first eleven months of 2025, the plant generated and sold about 9.2 Gigawatt hours, an increase of about 71% compared to the same period in 2024.
As a result, total revenues for the first eleven months of 2025 rose to around £1.45 million, the highest income generated over this period in any year and an increase of about 136% on the prior year. These revenues were achieved on an average production level of about 5.5 MW, equivalent to roughly £286,000 per MW per annum.
Meanwhile, Pyebridge achieved an average electricity sales price of around £139 per megawatt hour for the period, representing an outperformance of approximately 71% versus the average wholesale electricity price. The plant generated and sold electricity for an average of eleven hours per day, highlighting both the strength of demand for flexible generation capacity and the robustness of Quantum's operating model.
Quantum Data Energy’s Head of Finance Tanya Zwemstra said: “We are pleased to report that Pyebridge consistently delivered monthly electricity generation exceeding 1 GWh for three consecutive months, accompanied by strong revenue performance.”
“This achievement highlights QDE's unwavering commitment to delivering reliable energy to the UK grid through scalable, flexible, modular power solutions.”
