CREATION AND CORRECTION OF FUTURE TIME INTERVAL POWER GENERATION CURVES FOR POWER GENERATION COSTING AND PRICING
First Claim
1. A method for creating projected power production data comprising:
- storing historical heat rate curves and historical process information for at least one power generation unit in a historical heat rate curve database;
retrieving at least one historical heat rate curve from the database for a selected time interval;
correcting the at least one historical rate curve using correction factors which are based on differences between the historical process information and projected process information; and
creating a projected cost curve for a future time interval based on at least one corrected historical heat rate curve.

Abstract
Methods, apparatus, and articles of manufacture such as software media for creating projected power production data are disclosed. The method may comprise storing historical heat rate data and historical process information for at least one power generation unit in a historical heat rate database. The method may also comprise retrieving the historical heat rate data from the database for a selected time interval and correcting the historical rate data using correction factors which may be based on differences between the historical process information and projected process information; and creating a projected cost or a projected price for a future time interval based on the retrieved historical heat rate data.
