June 2025 (2025-06) monthly summary for NREL/REopt_API focusing on delivered features, fixes, and business impact. Key features delivered: - REopt.jl dependency updates and cost parameter alignment to stabilize model costs and O&M across branches, including updates from v0.53.0 through v0.53.1 and development branches, ensuring consistent inputs for financial calculations. - Electric Storage cost modeling enhancements, adding om_cost_fraction_of_installed_cost and updating defaults to reflect 2024 dollars for improved cost accuracy and budgeting. - Expanded test coverage by adding new ElectricStorage inputs to all_inputs_test.json to validate handling of new configurations. - BAU capital cost fields introduced in FinancialOutputs: initial_capital_costs_after_incentives_bau and lifecycle_capital_costs_bau to improve BAU financial reporting. - Boiler and Chiller installed cost and size tracking added to ExistingBoilerInputs/Outputs and ExistingChillerInputs/Outputs for better capital planning and asset management. - Documentation updated: CHANGELOG now reflects merged branch changes, PV/battery cost parameters, and GHP inputs validations. Major bugs fixed: - Database Migrations Consolidation: merged Django migrations to resolve dependencies and ensure a coherent migration sequence, reducing deployment risk and migration errors. Overall impact and accomplishments: - Strengthened model fidelity and financial accuracy for REopt_API, enabling more reliable cost, LCOE, and NPV analyses across projects. - Improved testing stability and data integrity through expanded inputs and stabilized migrations, accelerating future development and releases. - Clearer governance for cost parameters and BAU reporting, supporting better business decisions and financial planning. Technologies/skills demonstrated: - Cross-language integration (Julia: REopt.jl; Python/Django); JSON-based configuration; cost modeling and NPV/LCOE considerations; test data management; Git-based release discipline and migration governance.

May 2025 focused on stabilizing core REopt API delivery while expanding capability for size-class driven cost modeling and data integrity. Deliveries span migrations consolidation, CST data model integrity, API access configuration, and cost-modeling enhancements, with dependencies updated to validate sizing features.

April 2025 - NREL/REopt_API Monthly Summary: Focused on delivering features that improve resource efficiency, expand visibility into demand and costs, and harden CI/CD and data reliability. Delivered concrete business value through targeted resource optimization, enhanced reporting metrics, and robust fixes across the deployment lifecycle.

March 2025: The NREL/REopt_API team delivered substantial enhancements to financial modeling and emissions reporting, reinforcing business-value decision support and API reliability. Key features were implemented, including an enhanced FinancialOutputs model with granular capital costs, O&M, and CHP standby cost reporting; alignment with REopt.jl for emissions calculations and API migrations; and comprehensive emissions reporting improvements with CO2e labeling, per-year units, and improved workbook/user documentation. Critical reliability fixes were addressed: lifecycle CHP standby charge reference corrected and a BAU ExistingBoiler load workaround; CO2 labeling consistency updated across the workbook. These efforts improved total cost of ownership accuracy, emissions reporting readiness, and developer usability, while showcasing strong cross-repo collaboration, dependency management with REopt.jl, and thorough documentation practices.

February 2025 highlights focused on strengthening financial modeling, reliability, and deployment stability across NREL/REopt.jl and NREL/REopt_API to improve decision support for stakeholders and speed of iteration.

January 2025 performance summary for NREL REopt platforms (NREL/REopt.jl and NREL/REopt_API). Highlights include leap year accuracy fixes for URDB rate tariffs, expanded leap year test data (2023–2024) and year-input alignment across CoolingLoad, ElectricLoad, and HeatingLoad, along with substantial test infrastructure improvements and release-readiness work. The work delivered improved model accuracy, reliability in annual energy/cost calculations, and clearer, maintainable code and documentation, positioning the project for v0.50.0 release.

2024-12 monthly development summary for NREL/REopt.jl and NREL/REopt_API. Focused on delivering high-value features, stabilizing tests, and improving release readiness. Highlights include enhancements to financial modeling accuracy, input validation improvements, and cross-repo reliability, with emphasis on business value and technical excellence.

Concise monthly summary focusing on key accomplishments for 2024-11 across REopt_API and REopt.jl with emphasis on data integrity, expanded financial visibility, and end-to-end validation. Overall, this month delivered improvements in data handling, input hygiene, testing, and financial reporting metrics, strengthening the reliability of investment decisions and project economics.

Concise monthly summary for 2024-10 focusing on delivering robust load-profile capabilities and API readiness across REopt.jl and REopt_API. Key outcomes include enhanced input validation and normalization for simulated_load, standardized load_type handling for heating loads, expanded load-profile input capabilities (year, vector inputs, normalize/scale flag), POST support for simulated_load, broader test coverage, and a dependency update to ensure alignment with the latest features.
