Quantum Data Energy (MAST ) said its 100% owned Pyebridge 8.1 MW flexible generation power asset delivered record electricity generation and revenues for the calendar year 2025.
Electricity generated and sold in 2025 totalled around 10.8 gigawatt/hours (GWh), up around 71% versus the prior year. Meanwhile, revenues for the year rose sharply year-on-year, with the company reporting total 2025 revenues of around £1.6 million, its highest for any calendar year to date.
In addition, Pyebridge generated and sold around 1.6 GWh in December 2025, which the company said was the highest monthly output achieved by the asset so far.
Quantum Data Energy attributed the sustained high output to robust operational performance and growing demand for flexible generation capacity, particularly as intermittent renewable supply increases. Over the year, Pyebridge averaged around 5.6 MW in production, equating to around £291,000 per MW per annum in revenue.
The company also highlighted that Pyebridge achieved an average realised electricity sales price of around £135 per MWh during 2025, which it said outperformed the average wholesale market electricity price by around 67%. The plant generated and sold electricity for an average of 11 hours per day across the year, which it views as further validation of its flexible generation model.
Quantum Data Energy’s CEO Pieter Krügel said: "We are very proud of the 2025 full year results that we achieved with our Pyebridge asset, which represent record high electricity generation and revenues. The results underscore the successful outcome of the refurbishment programme at Pyebridge, as well as the ongoing strong demand for flexible generation power amid intermittent renewable supply. QDE's core business model is to generate and supply flexible power at a premium when the national grid is constrained, and that business model is clearly working very well. We are looking forward to 2026 during which we plan to grow our portfolio of assets as we advance toward our first target of 300 MW at some pace."

A strong full-year performance at Pyebridge underlines how valuable dispatchable, flexible capacity can be when power markets are balancing higher renewable penetration. If the asset can maintain this level of utilisation and pricing through 2026, it should provide a solid cash-generating base for the group while it assesses further opportunities in flexible generation.
