Notes
Plant-specific greenfield capex was found in a 2021 project announcement: estimated cost of $150 million for the 150 MW/150 MWh Hazelwood Battery Energy Storage System, funded by ENGIE and Macquarie's Green Investment Group, with construction commencing in late 2021 and commissioning in 2023. The user-provided capacity for this DUID is 40 MW, but the source figure applies to the full Hazelwood battery project, not a 40 MW unit. No project-specific O&M was found; server-side default O&M was retained. The project is a battery storage asset with no fuel, heat rate, or emissions intensity in operation.
