Notes
Project-specific source states direct investment of approximately $1.5 billion for the Portland Energy Park. Project website states the battery has an initial lifespan of 20 years. No plant-specific O&M, fuel, or performance data beyond defaults were found; O&M defaults retained. Capex assumes the full 1,000 MW / 2,500 MWh project rather than a subset, consistent with the project description.
