INTESA SANPAOLO ONCE AGAIN AT THE FOREFRONT IN THE UNITED STATES:
NEW FINANCING FOR ENERGY STORAGE PROJECT IN NEVADA

• The IMI CIB Division participated in a ~US$290 million financing to support Roccasecca battery energy storage project
• The transaction adds to the Group’s numerous initiatives in the renewable energy sector, such as the Big Muddy solar project in Illinois
• Nicola Doninelli: “This transaction confirms our commitment to supporting the development of advanced energy infrastructure in the United States”.

Milano/New York, 1 April 2026 – The IMI Corporate & Investment Banking Division of Intesa Sanpaolo, led by Mauro Micillo, has participated with a pool of international banks in a financing of approximately US$290 million in favor of a battery energy storage project located in Boulder City, Nevada.

The financing will support the construction and operations of the Roccasecca project, a 127 MW / 506 MWh battery energy storage system currently under construction and expected to reach commercial operation in 2026. Once completed, it is expected to contribute to strengthening grid reliability and flexibility in the U.S. Southwest power market.

The financing is in connection with the sale of the Roccasecca project by IOWN Energy, on behalf of its client Eolus North America, to DESRI, a leading independent power producer.

Battery storage is a key enabler of the energy transition, and we are pleased to leverage our project finance capabilities and sector expertise to support projects that contribute to a more sustainable and resilient energy system.”

The initiative further strengthens Intesa Sanpaolo’s footprint in the United States, a strategic market where the IMI Corporate & Investment Banking Division continues to support the development of sustainable and resilient energy infrastructure.

This transaction adds to the numerous projects in which the Bank has supported renewable energy transactions across the country, including the financing of the Big Muddy solar project in Illinois, one of the most significant photovoltaic plants in the Midwest, reaffirming the Group’s commitment to accelerating the energy transition across the Americas.
