The retrofit of two coal-fired generating units (847 MWe) at San Juan Generating Station with Mitsubishi Heavy Industries’ (MHI) KM CDR Process™ for CO2 capture.

Both operating units (Units 1 and 4) were equipped with environmental controls for nitrogen oxides, sulfur dioxide, particulate matter, and mercury, making the SJGS facility carbon capture-ready from an emissions perspective.

The City of Farmington, a part-owner of SJGS, would have been jointly responsible with Enchant for site-specific decisions regarding the SJGS. Enchant would have managed the CO2 capture retrofit process and would have been responsible for decision-making related to the overall direction of the project.

On December 20, 2022, the City of Farmington announced that they withdrew from the project at following unsuccessful legal challenges to keep SJGS in operation.
