Does PG&E prefer a plant design with significant Duct Firing capacity?
PG&E will calculate the costs and benefits of any specific proposed plant design. It will take into account the costs of specific design considerations including the long-term operational costs such as increased heat rate and/or reduced output at normal operating loads, and maintenance expenses, as well as the benefits of the additional capacity and operational flexibility. 4) In completing Appendix E “Guarantee at Peak July Conditions”, many of the closest geographically weather stations on the NCDC website do not contain a full 10 years of data. Would you prefer more data from a site further away, or accept the closer weather station if there are >5 yrs of data available? Should we calculate performance at the average relative humidity as well? (11-18-04) Please use the weather station site that best approximates the temperature and humidity conditions of plant site and has 10 plus years of consistent data. The calculations should include both temperature and humidity.
