August 2025 monthly summary for pik-piam development work. Focused on delivering stable version management, reliable CI workflows, and foundational model improvements for REMIND integration, with thorough documentation and release housekeeping. Highlights include new version management for piamInterfaces, cleanup of ECEMF mappings, CalcSeProduction implementation and documentation in mrremind, and model feasibility enhancements through hydro potenial increases in Eastern Europe.

Month: 2025-07 — Focused feature delivery in pik-piam/piamInterfaces to enhance energy system cost modeling. Implemented Energy System Cost Mapping Enhancements by introducing new mapping variables for fuel cost, investments, and operation & maintenance (O&M) cost in the supply sector, enabling more granular cost analysis and robust financial planning. Key commit: 7299c0115e6a97eef9e5292f167750cc704ebee2 (message: add energy system cost variables).

Monthly summary for 2025-05 (pik-piam/piamInterfaces): Delivered ECEMF Variable Expansion and updated documentation, plus critical fixes to Transportation Emissions Mapping in ECEMF CSV. This enhances model coverage (capacity, capital costs, emissions, final energy, and trade), improves data integrity for energy demand with/without bunkers, and cleans up project metadata to prevent conflicts. Result: better accuracy in emissions and energy accounting, streamlined release with refreshed versioning and README, and increased maintainability.

November 2024 performance for pik-piam/piamInterfaces focused on data integrity in multi-region uploads and clear release governance. Delivered a critical bug fix to ensure EU27 is included in EU21 uploads when auto drop is configured, and completed a release-management update by bumping the package to 0.36.10 with an updated release date. These changes stabilise cross-region data flows and improve release cadence for the module, reducing production risk and supporting reliable deployments.
