Tuesday September 15, 2026 09:20 - 09:30 CEST
Main Stage
Europe's energy transition has hit an inconvenient truth: we cannot build grid fast enough. Investment needs reach €584 billion by 2030 and €1.2 trillion by 2040, yet permitting still takes the better part of a decade, roughly 1,700 GW of renewables sit waiting in connection queues, and in 2024 Germany alone spent €2.8 billion simply managing congestion.

PowSyBl runs load flow in production at TSOs; its short-circuit side is younger. We do not need a perfect fault engine to make the next leap. Treat PowSyBl as a *grid engine* — it gives the short-circuit power Scc, the fault current Icc, line parameters and source strength, the boundary conditions a protection study needs since relays are set on Icc min and max.
