Notes
No project-specific greenfield capex figure was found in owner/developer, government, or project documents. Available official sources confirm Pacific Partnerships is developing the Cobbora Solar Farm and co-located BESS, and third-party/project sources describe the battery as 400 MW / 1600 MWh for the overall Cobbora Project or 400 MW / 800 MWh in some references. The NEM entry provided by the user lists Cobbora BESS at 520.8 MW / 800 MWh, which appears inconsistent with the public project descriptions and should be reviewed. No verified O&M benchmark source was pulled because the request prioritized project-specific capex and the search results did not yield a plant-specific investment figure.
