## Data quality

- Reported capacity figures differ by source: PSEG’s station page lists 2,280 MW total and a 1,309 MW PSEG share, while Constellation lists its 43% share as 995 MW. This directory record therefore emphasizes the verified two-unit configuration and ownership percentages rather than selecting one nameplate figure. PSEG’s official station page reports commercial service in 1977 and 1981, while a later PSEG release reports 1976 and 1980; the timeline uses the station page’s unit-specific service years and avoids unsupported exact operating dates. No completed Salem retirement or repowering milestone was identified. Available operator and regulatory material instead describes subsequent license-renewal efforts and planned power uprates. The 2001 acquisition amount was a portfolio transaction consideration, not Salem-specific project financing.
