## Data quality

- The EIA plant record reports 417.50 MW of nameplate capacity, while 2014 transaction announcements round the facility to 417 MW; this directory uses 417.5 MW for EIA plant 3175. No retirement date is established. The documented 2013 equipment work was refurbishment of two generators rather than a stated repowering, and the project remains under a license expiring in 2030.
