What Atlantica Sustainable Infrastructure does

Atlantica Sustainable Infrastructure is a private sustainable infrastructure company that develops, owns, and operates a diversified portfolio of renewable energy, storage, and complementary infrastructure assets across 12 countries in North America, Europe, South America, and Africa. Founded in December 2013 and previously NASDAQ-listed (ticker AY), the company was taken private in December 2024 when Energy Capital Partners and co-investors acquired it for approximately $7.5 billion ($22 per share). Headquartered in London, Atlantica operates roughly 2.9 GW of generation capacity, 1,363 miles of high-voltage transmission lines, and a 10.4 GW development pipeline of new renewable and storage projects.

The company's asset base spans solar PV and parabolic trough concentrated solar power (e.g., Solana 280 MW and Mojave 280 MW), onshore wind (including the Vento portfolio in the US and assets in Canada, Uruguay, and Colombia), geothermal (the 135 MW Coso facility, the third-largest in the United States), standalone battery energy storage systems (Coso Batteries 1 and 2, totaling 180 MWh), a 300 MW natural gas cogeneration plant in Mexico serving Pemex, water desalination in Algeria, and district heating in Calgary. In-house operation and maintenance teams cover approximately 74% of consolidated revenue, and the integrated development function partners with junior developers across the US, Spain, Italy, Colombia, Uruguay, Chile, and Mexico.

Atlantica generates revenue primarily through long-term (15-25 year) power purchase agreements with investment-grade utility, government, and corporate offtakers such as APS, PG&E, SCE, Hydro-Québec, Idaho Power, the Kingdom of Spain, and UTE Uruguay. A second revenue stream comes from regulated transmission concessions in Peru, Chile, and Uruguay under fixed USD tariffs adjusted by US inflation. The company funds growth through both project-level non-recourse debt and corporate Green Senior Notes under a formal Green Finance Framework. First nine months of 2024 revenue reached $918.7 million (+7.0% YoY) with adjusted EBITDA of $657.5 million (+4.8% YoY), and the average remaining PPA contract life is 13-15 years, supporting high revenue predictability.

Broad incumbents

• Engie: Global energy utility and IPP with large renewable energy, transmission, and gas-fired generation portfolios across Europe, North America, South America, and Africa. Overlaps with Atlantica in renewable generation, transmission, and natural gas cogeneration but at much larger scale and broader scope.
