Notes
No plant-specific battery-only capex was found from the owner/developer/trust; the best available reported figure is the SEC's $370 million investment for the integrated Horsham energy park. Battery capacity is 100 MW / 200 MWh. Commissioning is targeted for 2027. Fixed OPEX uses server-side fallback because no project-specific O&M source was found. Emissions intensity set to zero for battery storage.
