Summary Comments:
- Ft. Nelson fresh water is steam injected during combustion to lower NOx emissions.
- Some data may differ from that appearing in previously-published reports due to updated power records obtained for those periods, differing reporting periods, revised CEA data, improved measurement or estimating techniques, or typographical corrections.
