About Ataca and Pantac

Ataca and Pantac are utility-scale solar photovoltaic generation assets in South America, held within Ardian's infrastructure portfolio. Ataca comprises three ground-mounted solar plants in northern Chile with combined capacity of 26.5 MW, while Pantac refers to the Peruvian solar plant at Tacna in the south of the country, rated at 19.4 MW at acquisition and later 22.2 MW. Together the assets were originally developed by the Spanish renewables group Solarpack, which retained operations, maintenance and day-to-day asset management following the initial investment. The plants sell power under long-term contracts in the Chilean and Peruvian markets, positioning the portfolio as a contracted, cash-generative renewable-energy infrastructure holding rather than a conventional operating company.

Ownership journey

The plants were built and brought into operation by Solarpack Corporacion Tecnologica, a solar developer active across the Chilean and Peruvian markets. In September 2016 Ardian, investing through Ardian Infrastructure Fund IV, acquired an 81 percent stake in the four solar photovoltaic plants for roughly USD 31 million, alongside a minority position in Solarpack and a seat on its board. The transaction, covering the Ataca assets in Chile and the Pantac asset in Peru, marked Ardian Infrastructure's first investment on the American continent. In January 2024 Ardian and Solarpack completed a strategic reorganisation of their joint venture, under which Ardian moved to full 100 percent ownership of the three northern Chilean plants and the Tacna plant in Peru. Ardian remains the active owner of the assets, and no exit or secondary sale of the portfolio has been recorded.

Under PE ownership

The 2016 acquisition gave Ardian an entry point into contracted South American solar generation while leaving Solarpack, as developer and specialist operator, responsible for running the plants day to day. Over the holding period the Peruvian Tacna asset grew from 19.4 MW to 22.2 MW of installed capacity, and in January 2024 Ardian consolidated the joint venture to gain full control of the Chilean and Peruvian plants it retained. Following that step Ardian transferred management to AGR-AM, its dedicated renewable-asset manager for Spain and Latin America, integrating the plants directly into its clean-energy platform. The reorganisation gave each party clean ownership of its respective assets, with Solarpack keeping the Panamericana and Moquegua plants in southern Peru.
