Germany's New Dynamic Grid Tariffs Leverage EV Flexibility for Enhanced Energy Efficiency

Johanna from UnternehmerTUM discusses the "Grids and Benefits" project, which aims to address the strain on Germany's electricity grid due to increasing electric vehicle (EV) usage. The current flat tariff system does not incentivize efficient energy use or reflect actual load demands. By implementing dynamic grid fees and leveraging EV flexibility through smart charging, this project seeks to manage demand peaks and renewable feed-in pressures effectively. It proposes cost-reflective network tariffs that are spatially and temporally granular, considering weather patterns for accurate load projections at medium-to-low voltage levels in specific regions known as "Entlastungsregionen." A 15-minute time resolution model is suggested with tariffs set a day ahead of market closure using a traffic light system initially for signaling grid conditions—green indicates surplus capacity while red signals congestion—which will evolve into complex price signaling linked to redispatch processes. An aggregator optimizes these price signals without consumer intervention during inconvenient hours like nighttime. Testing involves IT infrastructure by Transnet BW with components such as 500 EVs and home chargers aimed at enhancing public charging capabilities through partnerships like MeinGau’s involvement based on real-world data analysis focusing on congestion points within high-level coalitions promoting bidirectional charging initiatives supported collaboratively towards successful deployment outcomes.

Talk of session: How to Best Leverage EV Flexibility with Smart and Bi-directional Charging?

This session will explore how smart and bidirectional charging can improve grid integration and sustainability within EV infrastructure. We will also discuss how to make smart charging a mainstream solution, focusing on intuitive design, seamless integration with the grid and other sectors, energy management, and key legal considerations to create a more accessible and efficient charging ecosystem.
