## Data quality

- Public project sources describe Patriot as an 829 MW facility, while current EIA/FERC records list two 435 MW nameplate units and an 870 MW aggregate nameplate capacity; this directory uses the current 870 MW configuration. July 2016 is the EIA-recorded initial operation date, while the public Siemens/Panda commissioning announcement was dated November 16, 2016; both milestones are retained as distinct operating milestones. The plant received a 30 MW uprate effective June 2021, and a further 30 MW equipment upgrade was planned for 2026. The reviewed FERC asset rows do not identify a retirement or repowering event for Hamilton Patriot.
