BlueSky - BlueSky Release v1.1

Version 1.1 Release Notes

In April 2025, EIA released Version 1.1 of the Project BlueSky prototype model. Given current resource constraints, EIA will pause future Project BlueSky model development activity.

Project BlueSky enabled EIA to explore new energy modeling approaches, and this foundational work will serve as a basis for EIA’s future long-term model development efforts as EIA continues to advance its energy modeling capabilities.

What's Changed

• cleaned up code formatting, addressed bugs.
• reorganized layout of the prototype, e.g., moved input files to parent directory.
• created common subdirectory to house configurations and other scripts that are useful across the sectoral modules.
• created a model class within the common directory and added the class structure to the electricity model which allows for consistent declaration of model objects.
• added to sample directory: electricity_data_pipeline which generates some of the electricity input files from their source data, such as the variable renewable energy capacity factors, the capacity supply curves, transmission-related data, and others.
• added to sample directory: enduse_data_pipeline which generates the end-use shapes residential input files from its source data.
• Added to sample directory: baseload_data_pipeline which generates the base load residential input file from its source data.
• Added to sample directory: integration_rebuild which hosts an in-development version of a redesigned and refactored model instantiation and integration architecture
• changed layout of BaseLoad input file so that it only includes load data for the initial model year and future years as adjusted based on end-use category input assumptions.
• added checks within configurations to limit users passing wrong information and updated more unit tests.
• renamed indices within the electricity model

BlueSky - BlueSky Initial Release v1.0

On October 31, 2024, we released the BlueSky Prototype publicly via GitHub under the Apache 2.0 open-source license. This basic prototype is the first step toward creating a next generation model. The prototype includes:

• data pipeline structure and pre-processors
• sample modules that represent residential demand, hydrogen production and distribution, and the electric power sector
• two different integrated solution techniques
• and two different methods to test the sensitivity of results.

Given the prototype's limited scope, we have omitted any reference to a specific country, region, or timeframe in the input data.
