Prospex Energy cuts Romeral operating costs after transformer installation
Prospex Energy (PXEN) has completed the installation of a new transformer at its Romeral gas-to-power plant in Andalucía, Spain, replacing a rental unit and cutting monthly operating costs by ~€14,000.
The replacement transformer was ordered in September 2025, with a rental unit installed in February 2026 to support generation while the new equipment was manufactured and made available for installation.
Operator Tarba Energía successfully completed the swap between 9 and 10 September, with generation and power exports resuming on 11 September. Overnight generation on 10 September reached 15.25 hours, with generation continuing since then.
Prospex CEO Tom Reynolds said: “I am delighted that the operation to swap out the rental transformer with its permanent replacement has been achieved safely and with minimum disruption to generation activity. The plant is now exporting electricity, supported by strong electricity pricing.
“It is important to note that Tarba has been self-sufficient through July and August, demonstrating its potential to generate sustainable cash flow; the €14,000 per month reduction in rental fees will further enhance its profitability. The successful operation is a testament to the hard work and proficiency of the Tarba team.”
View from Vox
The transformer installation removes a meaningful recurring cost and comes as Romeral benefits from solid generation and supportive power prices. The more important development is that Tarba has been cash self-sufficient through the summer, reducing the funding burden on Prospex.
