## Data quality

- The 1,098.2 MW figure is the plant's EIA-based total nameplate capacity; other published sources report different figures, including approximately 1,130 MW and 1,193 MW, reflecting differing rating or aggregation bases. The LS Power transaction was announced in March 2026 and remained subject to regulatory approvals, with closing expected later in 2026; it should not be treated as a completed acquisition as of August 2, 2026. No separate retirement or repowering milestone is identified in the cited plant records.
