Requirements of the integration of renewable energies on the regulation of network charges

German energy and climate policy aims to reduce greenhouse gas emissions by 40% until 2020 and by 80-95% until 2050 compared to 1990 levels. One central measure to reach this goal is the expansion of renewable energies in the power sector. The share of renewable in electricity generation shall increase to at least 80% by 2050. This target requires a transformation of the power system not only at the generation stage but also requires changes on the demand side and in the network.

Objective

This project undertakes an analysis of the current German network tariff system and possible advancements in the context of an electricity supply system based on renewable energies and the consequently altered network utilization. The analysis addresses incentive structures, cost allocation, and distributional effects under special consideration of self-generation, network tariffs for generation (G-component), and regional differences. In the end recommendations for the advancement of the network tariff system in the context of a RES-E based system will be derived.
