BDO brought in to oversee insolvency of Portugal’s largest solar facility Solara4
The company behind Portugal’s largest solar power station has entered insolvency proceedings after the €175 million project in the Algarve failed to generate enough revenue to cover its debts.
Welink Energy Portugal 2 UK, the British-registered parent of Solara4, is now under the oversight of BDO, which is managing the restructuring process on behalf of creditors. BDO is a global professional services firm, with the engagement led by its Restructuring and Insolvency practice.
The 220-megawatt plant is located close to the border with Spain in the southern municipality of Alcoutim. It currently remains operational despite the ongoing insolvency filing. According to reporting from Expresso, advisers are working to stabilize the facility’s performance while preparing it for a possible sale to new investors.
BDO has been brought in to oversee the insolvency proceedings, a role that generally places a consultancy at the center of coordinating between a distressed company, its creditors, and any potential buyers.
In cases like this, the overseeing firm is usually tasked with assessing the company’s financial position, reporting findings back to creditors. The consultants will decide whether it is best to restructure or sell the business, depending on which option can maximize recovery for those still owed money.
This kind of engagement typically includes reviewing operational and financial records, identifying the root causes of underperformance, and evaluating whether the underlying asset, in this case a working power plant, still holds enough value to attract buyers. The firm overseeing proceedings often does not run day-to-day operations itself; rather, it monitors the process and reports on progress while specialists come in to take over operational management.
Indeed, the Alcoutim facility has been transferred from Ireland’s Welink Investments to renewable energy company Exus, which is working alongside energy consultancy Enertis to determine what investment is needed to improve production.
Falling prices and technical setbacks
The insolvency follows a difficult stretch for Solara4. A damaging mix of lower-than-expected electricity production, technical failures, fires, and falling wholesale energy prices has strained the project’s finances. The rapid expansion of solar generation across the Iberian Peninsula has pushed prices to zero, and at times below zero, during periods of high supply, leaving the plant with far lower revenues than originally forecast.
The facility has also suffered several fires within the past year, damaging equipment and driving up maintenance costs. Some incidents were tied to equipment failures, including problems with inverters that left sections of the plant offline for extended periods.
The principal creditors are reportedly Investec and Kommunalkredit Austria, which helped finance construction with an initial €100 million and are still owed around €64 million. The project is also caught up in a €143 million dispute with CTIEC, a subsidiary of a Chinese state-owned construction group, over alleged unfinished work following the end of its contract in 2023.
A hybrid plan still awaiting approval
Welink has argued that the solar plant cannot remain viable on its own and has proposed combining it with wind generation and battery storage to diversify income. Earlier plans called for 25 wind turbines, additional solar capacity, and a battery park, but the proposal drew strong environmental objections over its proximity to breeding grounds used by eagles and other protected species.
A revised version has been under public consultation, and a final decision from Portugal’s environment agency remains pending.
With its parent company now insolvent and creditors preparing for a possible sale, the future ownership of Portugal’s flagship solar project remains uncertain, even as BDO continues its work behind the scenes to guide the process toward resolution.
