Pieter Krügel, CEO of Quantum Data Energy PLC, said: "We are delighted to confirm that construction of our Bordesley 5 MW FlexGen project has commenced at pace and is progressing on schedule and on budget. With the civils, electrical, genset and gas packages all placed during March 2026, the project is now firmly into delivery mode. Our partnership with Power Balancing Services Ltd validates QDE's capital-light scaling model, allowing us to retain meaningful equity exposure to a high-quality, cash-generative asset while limiting dilution for our shareholders. Bordesley will be QDE's third operational flexible generation asset and represents another important step toward our 300 MW target and beyond. The £1m placing recently completed enables to progress other "shovel-ready" sites with the capital providing the potential for necessary capital contributions alongside project level debt financing discussions which are currently underway which we hope to be able to announce to the market in the coming weeks."
