Spanish infrastructure and renewable energy conglomerate, Acciona has announced that it has signed an agreement with the US-based company Tenaska to acquire a portfolio of solar PV projects in seven states across the country. The portfolio comprises approximately 3,000 megawatts (MW) of rated power in utility-scale solar plants and an additional 1.000 MW capacity of battery storage.

The transaction covers 20 projects located in the States of Pennsylvania, Ohio, Kentucky, Illinois, Kansas, Oklahoma and Missouri, within the scope of the PJM Interconnection and Southwest Power Pool (SPP) markets.

“This operation represents an opportunity for Acciona to increase our commitment to renewable energy and sustainability in the United States through photovoltaic and energy storage technology, after the investments we have already made in wind power”, said Rafael Esteban, Acciona’s Energy Division director, North America. “We will materialise a large part of the projects between 2021 and 2023.”

Tenaska – through Tenaska Solar Ventures, the company’s solar development services business – will work with Acciona to complete development of the projects.

“We are excited to join forces with Acciona on this renewables portfolio, pairing Tenaska’s extensive expertise in development with their origination and construction capabilities,” said Steve Johnson, senior vice president of Tenaska Solar Ventures. “This transaction highlights Tenaska’s ability to monetise our team’s knowledge and skillsets while operating under various development models.”

The Spanish firm plans to put eight projects from this portfolio into service before the end of 2023, adding around 1,500 MW of peak power (some 1,200 MW of rated power) to its renewable energy assets in North America, where it already has more than 1,245 MW of wind power capacity installed or under construction. 

The addition of a 1,000 MW energy storage development portfolio allows Acciona to offer cutting-edge technologies and services to these U.S. markets.

Globally, Acciona owns and operates around 10,000 MW of renewable energy capacity worldwide, in 16 countries on the five continents.
