Ideas and Concepts for an Efficient Decentralized Energy Transition in Germany

The German energy transition is facing several systemic design flaws that hinder the optimal integration of decentralized renewable energy resources such as residential photovoltaics and battery storage systems. This paper analyzes technical and regulatory barriers within the current smart metering infrastructure, grid pricing models, and inverter grid codes. It further proposes a set of practical and technically grounded solutions — including a pricing scheme, simplified metering architectures, local powerline communication, and improved inverter grid code requirements — to enable a more robust, decentralized energy system.
