Confidence: medium · Status: ai estimated · Capex basis: reported · AI checked 06 Jun 2026

Notes
Plant-specific greenfield capex was not found in official owner/government sources; a 2021 industry report stated ATCO had bought the rights to develop the project for $500m. Government sources confirm the project is 325 MW and 2,600 MWh (8 hours). The capex figure appears to be a project acquisition/development cost reported in media, not an owner press release, so confidence is medium.
