# ATOME picks Sungrow Hydrogen for 260,000 t/yr Villeta low-carbon fertilizer plant in Paraguay

Publication Date: 05.06.2026, 10:00

The 110 MW alkaline electrolyser order, powered by Itaipu Dam hydropower, advances one of Latin America's first utility-scale green nitrogen plants.

[ATOME](https://www.atomeplc.com/) has selected Sungrow Hydrogen to supply the electrolysers for its 260,000 t/yr low-carbon fertilizer plant at Villeta, Paraguay, following a competitive tender managed by EPC partner Casale.

The project will deploy 110 MW of Sungrow's alkaline electrolyser technology, powered by 100% renewable baseload hydropower from the Itaipu Dam, to produce the green hydrogen feedstock for 260,000 t/yr of low-carbon calcium ammonium nitrate (CAN). A long-term service agreement will cover maintenance of the equipment.

ATOME described the award as the start of a long-term partnership with Sungrow, with cooperation on further projects already under discussion. The selection follows direct equity investments in ATOME by Casale and Baker Hughes, which the company said support its strategy of offering a one-stop-shop package to project investors and lenders.

Villeta ranks among the first utility-scale green nitrogen projects in Latin America, a region heavily dependent on imported fertilizer. Calcium ammonium nitrate produced from hydropower-based hydrogen would give regional growers a domestically made, lower-carbon alternative to imported nitrogen.

Sungrow's appointment moves the flagship project toward construction as ATOME firms up its technology and financing partners.
