## Data quality

- Capacity figures use different conventions: EIA reports 574.6 MW of nameplate capacity, LCRA reports 556 MW of net maximum capacity, and project descriptions commonly refer to the plant as 540 MW. The City of San Marcos's 3.52% interest is an ownership and project-cost participation share, not sale consideration. No acquisition or sale transaction for this exact EIA plant was disclosed in the reviewed project, owner, contractor, or regulatory records; the records describe an LCRA-developed replacement project rather than a purchased asset. No separate expansion or repowering event was identified. The material change was construction of the replacement facility and retirement of the predecessor plant.
