The transformation of the energy system must be implemented at many different levels – for example through the instrument of municipal heat planning. The measures involved can significantly increase electricity demand in distribution grids, for instance through the growing use of heat pumps. For municipal heat planners, the effects of such measures on the expansion needs of the supraregionally connected electricity grid have so far been barely visible, or have only become apparent at a late stage, as the relevant planning requires detailed and sensitive grid data. The SKALE research project, funded by the Federal Ministry for Economic Affairs and Energy, therefore addresses the question of the extent to which local measures can be reconciled with the federal government’s overarching targets.

SKALE develops scalable and comparative methods to estimate the need for grid expansion in municipal energy networks across Germany. We start with an automated approximation of electricity distribution grids based on geodata. Additionally, we use grid expansion planning and heat planning approaches to compile comparable datasets, to enable municipal stakeholders to understand the systemic effects of local heat planning measures. To this end, the project participants are researching methods for estimating loads and electricity generation potential on the one hand, and existing grid infrastructures and grid expansion needs on the other, across the country and in simplified form. One of the intended outcomes is an online atlas that visualises indicators such as regional grid expansion needs and CO₂ savings.

In the SKALE project, the Institute of Networked Energy Systems is primarily addressing the question of how generally comparable and computationally viable energy network models can be generated on the basis of publicly available data sources in order to assess municipal heat planning measures. In addition, the Institute is examining, from an overall system perspective, how the electrification of heat supply affects the need to expand electricity grids.

Our core topics and challenges related to the SKALE project:

Research Group

Energy System Modelling

The Energy System Modelling research group is developing methods and solutions for the planning and operation of future energy infrastructures. The primary focus lies in examining how various technologies can contribute to creating energy systems that are sustainable, reliable, and cost-effective.

Challenge

Balancing energy supply and demand

The simultaneity of electricity generation and consumption is the basis for a stable energy system. While fossil and nuclear power plants have so far been deployed according to demand, the dominant renewable energies in the electricity system are heavily dependent on weather - and therefore not available at any given time.
