## Data quality

- Capacity figures use different conventions: EIA reports 440.3 MW of plant nameplate capacity, while project sources separately report 300 MWac solar, approximately 390 MWp solar, and 140.25 MW/561 MWh of storage. The project was publicly announced as operating on March 15, 2022, while MN8’s later project history identifies April 2022 as the commercial-operation period. The later transition to MN8 is described as part of MN8’s succession from the Goldman Sachs Renewable Power platform rather than as a separately priced project sale. No separate expansion, battery augmentation, repowering, or retirement milestone is identified in the project history summarized here.
