Siemens has quietly hinted at (expected late 2025 or 2026). Rumored features include:
Version 36.1 added example renewable dynamics data and improved setup files for Geomagnetically Induced Current (GIC) calculations, facilitating faster modeling of modern energy systems.

Why it matters: If you try to simulate a 500 MW solar plant using synchronous machine models, your transient stability results will be wrong by an order of magnitude. Version 35 fixes this physics gap. Siemens has quietly hinted at (expected late 2025 or 2026)
