Prospex Energy Cuts Romeral Costs with New Transformer
Prospex Energy has completed installation of a new transformer at its Romeral gas-to-power plant in Andalucía, Spain, replacing a rental unit and reducing operating costs by approximately $16,200 (€14,000) per month.
The permanent transformer was ordered in September 2025, while a rental unit was installed in February 2026 to maintain generation during manufacturing. Operator Tarba Energía completed the replacement between 9 and 10 September, with generation and electricity exports resuming on 11 September. Overnight generation on 10 September reached 15.25 hours.
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.”
Reynolds said Tarba had been self-sufficient through July and August, while lower rental costs are expected to support profitability. Romeral is currently exporting electricity, supported by strong electricity pricing.
