Alexander Zolan contributed to the NREL/REopt.jl repository over six months, delivering seven features and resolving three bugs to enhance energy modeling capabilities. He implemented new parameters for forced dispatch of ASHPs, improved annual electric load calculations, and integrated technologies like CST and HighTempThermalStorage, focusing on both technical rigor and business value. His work involved code refactoring, changelog management, and thorough documentation using Julia, Markdown, and TOML. By addressing tariff calculation logic, emission factor handling, and renewable energy reporting, Alexander improved modeling fidelity, maintainability, and transparency, demonstrating a methodical approach to both feature development and codebase reliability.

February 2025: Completed the Electrical Load Calculation Improvements and Reporting feature in NREL/REopt.jl, introducing a new annual electric load result with thermal conversions and clarifications for electrified vs non-electrified thermal loads. Documentation and comments were updated to improve clarity on load aggregation and renewable energy definitions, and the CHANGELOG was reconciled to reflect the total site load. This work enhances the reliability of site-level load reporting and supports electrification planning.
