U.S. recognizes four new renewable energy awards against Spain

Judge Randolph Moss of the U.S. District Court for the District of Columbia issued four rulings in favor of investors in the OperaFund, Schwab, Steag, and Renergy cases, Spanish media reported on October 7, 2026. The rulings order the recognition in the United States of arbitral awards linked to changes in remuneration for renewable energy in Spain.

The decisions add 98.1 million euros, including compensation, costs, and interest, to the obligations recognized in that country. With these rulings, the number of U.S. decisions against Spain rises to thirteen, and the amount recognized or enforceable there approaches 935 million euros, according to media coverage. These figures describe obligations recognized by courts; they do not establish that any amounts have been paid.

Four claims linked to wind investments

The disputes concern investments in Spanish wind farms by companies based in Malta, Switzerland, Germany, and Luxembourg. The investors brought their claims before the International Centre for Settlement of Investment Disputes (ICSID) following regulatory changes that, between 2010 and 2014, modified the economic terms of the incentive scheme.

According to published reports, the amounts of the awards before adding costs and interest are 29.3 million euros for OperaFund and Schwab, 27.7 million euros for Steag, and 32.9 million euros for Renergy. Surcharges and additional items bring the total associated with the four proceedings to 98.1 million euros.

What the U.S. court decided

Moss denied Spain’s requests to dismiss or stay the proceedings and ordered judgment in favor of the creditors. According to news reports on the rulings, the judge held that ICSID awards must receive the same recognition in the United States as a final judgment of its own courts. He also indicated that Spain had not disputed the amounts claimed, so they were recognized in full.

The Spanish defense had raised, among other arguments, issues related to European Union state aid rules, the competence of European Union institutions, and international comity. The court did not accept those objections in these proceedings. The decisions described concern the recognition and enforcement of the awards in the United States; they do not in themselves mean that payment has been collected, nor do they allow the claim that any specific asset has been attached.

A dispute with cumulative financial effects

Before these rulings, nine U.S. proceedings—including Watkins, Antin, RREEF, and Eurus—totaled 836.6 million euros, according to media coverage. The figure of nearly 935 million results from adding the new cases and reflects amounts recognized or enforceable in that jurisdiction, not payments made.

The dispute is part of a broader conflict over enforcement of arbitral awards related to changes in renewable energy premiums. Spanish media have also reported rulings in favor of creditors in the United Kingdom, Australia, and Singapore. In each country, the routes for recognition and enforcement depend on its own procedures; the possibility of seeking measures against assets does not mean that such measures have been granted or carried out.
