Operational and Market Challenges
The insolvency report cites a combination of operational and market difficulties that hindered the plant's performance and cash flow. Electricity production has consistently failed to meet initial forecasts, while a surge in solar generation capacity across the Iberian market has driven wholesale electricity prices down, sometimes to zero or negative levels. Beyond market pressures, the project has faced technical issues and fires. Additionally, the company has been involved in disputes with its contractor, China Triumph International Engineering, a subsidiary of a Chinese state-owned conglomerate.
Failed Expansion and Future Outlook
In 2024, Welink proposed a €400 million 'hybridisation' project to add wind power and battery storage to the site, aiming for a total capacity exceeding 600 MW. However, the Portuguese Environment Agency (APA) issued an unfavorable opinion, citing concerns over environmental values in the area. A revised plan was submitted for public consultation, but the APA has not reached a final decision. Within the current insolvency process, the primary objective is to secure new investors to purchase the asset.
