William Hamilton enhanced capacity modeling in the NREL/SAM repository by implementing a configuration-driven adjustment to the MSPT sf_adjust scaling factor. He updated this parameter from 0.0 to 5.0 across multiple JSON configuration files, including IPH_LCOH Calculator, MSPT_All Equity Partnership Flip, and MSPT_Leveraged Partnership Flip, ensuring consistency across related scenarios. Leveraging his skills in configuration management and proficiency with JSON, William improved the fidelity of capacity calculations and enabled more accurate scenario analysis. His work focused on traceable, maintainable changes, supporting better cost estimation and decision making. The depth of his contribution reflects careful attention to configuration integrity.
