Abengoa was founded in Seville in 1941 and grew into a Spanish multinational building renewable energy, water and infrastructure projects in over 80 countries. By 2014 it employed about 20,000 people and reported €1.5 billion in annual sales. Growth was funded by project finance: each plant and desalination facility carried its own debt, nominally non-recourse to the parent. In practice, the parent guaranteed much of it.
By 2014, total debt had reached roughly €20 billion — most of it buried in project-finance vehicles that kept the parent's headline leverage looking manageable. On 25 November 2015, the industrial group Gonvarri pulled out of a €350 million rescue, and Abengoa entered pre-insolvency proceedings. In 2016 it posted a record €7.6 billion net loss. Two restructurings followed, in 2017 and 2019, but neither restored viability.
In February 2021, the parent company filed for bankruptcy. The regional government of Andalusia refused €20 million in aid; the state fund SEPI denied a support package in June 2022. By November 2022, the main subsidiaries were also in bankruptcy. A judge dissolved the parent on 1 July 2022. The assets were eventually sold to COX Energy Group, preserving over 11,000 jobs. It was the second-largest corporate collapse in Spanish history.
Abengoa's €20B project-finance debt, hidden in vehicles, triggered Spain's second-largest corporate collapse.
Project-finance debt let Abengoa grow without showing the leverage on its own balance sheet — until the guarantees were called and the structure became visible.
The company kept expanding into new countries and technologies (solar, biofuels, desalination) while its cash flow could not service the debt the expansion required.
When Gonvarri pulled out of the €350 million rescue, there was no alternative — the debt was too large for any single investor to backstop.
Project-finance debt that looks off-balance-sheet is still debt. Abengoa's guarantees turned a portfolio of independent projects into one highly leveraged company.
Abengoa's collapse cost creditors billions and prompted a review of Spain's insolvency framework, which was reformed in September 2022. The sale to COX Energy preserved the operating businesses and most jobs, but the parent company's shareholders were wiped out. The case became a warning about the risks of growth funded by project-finance leverage.
