TransitionZero's open source grid-model translator becomes core part of the Linux Foundation's OpenGrid

Climate tech non-profit TransitionZero said its open source translator, which converts power system models between frameworks and commercial tools including PLEXOS, PyPSA, Sienna and OSeMOSYS, has become a core part of OpenGrid, the Linux Foundation and Breakthrough Energy initiative launched the same day to modernise electricity-grid planning. Built with Breakthrough Energy support, the translator is part of TransitionZero's open core of free tools for energy modelling, and the organisation plans to add it to its no-code Scenario Builder platform so users can import their existing model files directly, citing IEA figures that more than 2,500 gigawatts of renewable, storage and large-load projects are stalled in grid connection queues worldwide.
