Worked on the catalyst-cooperative/pudl repository to deliver the EIA 860 Multifuel Table Integration, expanding the data pipeline to support multifuel generator capabilities. This involved designing new database tables and columns to capture generators that burn, co-fire, or switch between multiple fuels, and updating associated metadata and documentation. Database migrations were implemented to ensure seamless integration of the new schema, supporting richer fuel-type tracking for downstream analytics. Leveraged Python and SQL for data engineering and modeling tasks, focusing on ETL processes that enable more comprehensive reporting for users managing multifuel generators. No bug fixes were recorded during this period.
