Abstract
This article examines how volatile electricity prices driven by renewable energy integration challenge traditional industrial production logics in Germany. It highlights the conflict between flexible, market-oriented production strategies and regulatory incentives that still favour constant load profiles, particularly through individual network charges under §19 (2) StromNEV. By analysing the resulting economic trade-offs for energy-intensive firms, the paper reveals structural barriers to system-friendly demand flexibility. It concludes that realigning regulatory frameworks with the dynamics of renewable-based power systems is essential to unlock efficiency potentials and support the energy transition without undermining industrial competitiveness.
