FNN-Roadmap: Vom Netz zum System

The Energy System in 2030

Climate protection, the expansion of renewable energies and sector coupling require a systematic restructuring of the energy system. The power grid plays a key role in this by ensuring the secure integration of renewable generation plants and new consumers live electric vehicles and guarantee a reliable electricity supply. The distribution grid with centralized generation is becoming a network with decentralized players. VDE FNN vision "The Energy System in 2030" describes the path towards this system.

Our goals

We are making the energy system fit for the future: digital, flexible and reliable

  • Ensure an effective interaction of systems and participants in the power grid and make optimal use of their capabilities
  • Develop the Smart Metering system as a new part of the infrastructure to bring players in the system together, safely and reliably
  • Monitor and maintain reliability at a constant level despite increasing complexity of the grid

We bring the energy transition to the customer

  • Drive customer value for new energy world by enabling each customer to contribute to flexibility and reducing complexity in the system
  • Ensure an optimal involvement of all stakeholders and accelerate the implementation through technical rules and targeted measures
  • Promote standardised interfaces which are manufacturer-independent and compatible with different systems

We design a sustainable grid operation and contribute to climate neutrality

  • Optimize service life and environmental sustainability of plants to be upgradable, modular and contribute to the circular economy
  • Classify potential minimization of grid losses and implement sustainable path management strategies as well as improve sustainable maintenance of network equipment
  • Help shape the framework:
    • Contribute to European standards and solutions as a basis for the development of the power grid
    • Manage and accelerate the integration of renewable energies transparently

Towards a “climate protection grid” by 2030 - our roadmap

VDE FNN has defined its vision for the energy system in 2030 through a roadmap, which provides concrete details from VDE FNN continuous work and points to solutions for the challenges ahead.

Our main action points are:

  • Supporting the system transformation while ensuring a secure and reliable energy supply
  • Bringing the energy transition to the customer
  • Developing grid operation in a climate-friendly and sustainable way

No system design without rulemaking

VDE FNN has developed the so-called "FNN Scenario" to ensure that technical regulation is developed consistently and with foresight. To this end, FNN experts regularly analyze existing scenarios and resolutions, such as the grid development plan of the Federal Network Agency, climate summits and targets for electric mobility, and develop them further. The scenario for 2030 contains concrete assumptions for system-relevant variables such as gross electricity consumption, the number of electric vehicles on the streets and the performance of storage systems and power-to-X plants. The scenario compares to data from 2018 and presents variables in different categories: generation, load, flexibility and infrastructure. The 2030 scenario lays out the assumptions onto which VDE FNN bases its work on rulemaking. This provides the energy sector with orientation as well as planning and investment security. The 2030 scenario is the basis for the work of VDE FNN together with the roadmap "From grid to system", which was presented at the 2017 congress and has been continuously implemented since then.

The VDE FNN Sensitivity column describes the topics which are influenced by the changes in the key parameters of the scenarios. Areas of work such as the regulation framework or technical requirements for e-mobility must adapt to the evolving system. VDE FNN continuously monitors these developments and proposes solutions for the energy system by 2030.

Main areas of work

European Network Codes

The European network codes are network requirements for a cross-border electricity exchange harmonized on a Europe-wide basis. The goals are to improve the internal market for electricity and establish a functional and transparent wholesale market. VDE FNN describes in the VDE-applications rules both the concrete EU specifications and the specifics for the German electric power system.

Compatible network connection for energy storage

Storage systems are an important component of the energy transition. They offer the possibility to bring more flexibility into the energy system. Especially in combination with renewable energies, they offer the possibility to supply electricity from sustainable sources even when they are not generating electricity.

Interest in E-Mobility is growing. The decisive factor for the success of E-Mobility is a proper integration into the energy system from the outset. In this way, E-Mobility can be deployed faster, cost-effectively and can serve as additional support for the entire power system.

Environmental protection

Every measure has an impact on the environment and nature, which must be included from the beginning. Defining effective measures, e.g. for bird protection or minimising electromagnetic fields and contributes to investment security. FNN is as a key contact for environmental associations.
