Without information and communication technologies, energy supply has become inconceivable. They enable the flow of information between energy providers, consumers, transformer stations and other subsystems, monitor the grid and sound the alarm in the event of problems. At the same time, digitalization involves risks such as manipulation, cyber attacks and defective applications. Energy supply is a critical infrastructure (KRITIS). A blackout would therefore have far-reaching consequences for society. The claim is: Digital energy infrastructures must be both secure and safeguarding. This means that they must be able to defend themselves against attacks and failures and at the same time keep the entire system functional. What opportunities and what challenges however could arise? Who are the main players and what is their responsibility? What needs to be done at regulatory level and in practice? The ESYS working group “Resilience of Digitalized Energy Systems” develops scientific based policy options to deal with these questions.

The regulatory issues in the electricity market today are different from the issues that characterised the liberalisation phase at the turn of the millennium and strongly influenced the German energy market’s current design. Consequently, this market design now needs to be adapted to the new conditions. In view of the likely future challenges, it is necessary to fundamentally rethink the market design’s ongoing development in the light of past experience. An optimised market design can deliver climate protection targets more efficiently and effectively, improve the integration of renewable energy and contribute to security of supply. The working group is formulating proposals and identifying policy options for restructuring the electricity market in order to enable decarbonisation of the energy system by the 2030 deadline. To this end, it is examining the European emissions trading scheme, the promotion of renewable energy and the interactions between the electricity industry and the transport and heating sectors.

As a result of the growth in renewable energy, electricity is now produced in smaller generating units as well as in large power plants. More and more private individuals, companies and municipalities are feeding power into the grid from their own wind or photovoltaic installations. While many people regard this development as an opportunity to play an active part in the energy transition, it remains unclear how the trend towards a decentralised energy supply will affect the overall system. Will a viable new system architecture emerge, or will the energy system become fragmented, resulting in more and more problems? The Working Group aims to demonstrate how centralised and decentralised components can be integrated to create a stable supply system. To this end, it is investigating the technical options, the regulatory framework and the economic, social and policy issues.

The 2030 Agenda for Sustainable Development and the Paris Climate Agreement establish the goals of limiting global warming to well below 2°C and achieving global greenhouse gas neutrality by the second half of the century. In order to meet this challenge, it will be necessary to reorganise Europe’s energy supply into a common European system. The Working Group is studying the regulatory, policy and economic framework of European energy policy, particularly in terms of existing barriers to the establishment of a European energy union. Based on its findings, it is developing governance guidelines for a sustainable, secure and affordable energy union geared towards achieving complete carbon neutrality. The Working Group aims to identify the best way of managing this process, as well as how to distribute the relevant tasks fairly and efficiently among the EU’s members and how to involve civil society and the private sector.

Bioenergy has several advantages. Being easy to store, it can compensate for fluctuations in wind and solar power and can also generate heat. As well as being used to produce fuel, biomass can be combined with CCS technology to remove greenhouse gases from the atmosphere. Climate models suggest that this will be necessary within the next few decades. However, there are also a number of drawbacks. Unless sustainability criteria are enforced, the cultivation of energy crops will produce greenhouse gases, have a negative impact on biodiversity and soil quality, and cause water pollution. The Working Group aims to identify the best options for the sustainable, climate-friendly use of bioenergy as part of our energy supply.

If the goal of reducing carbon emissions by 80 to 95 percent is to be met, switching electricity generation to renewable sources will not be enough on its own – it will also be necessary to ensure more climate-friendly energy production for the heating and transport sectors. This will require technologies such as Power-to-X, which uses electricity to produce heat, synthetic gas and fuels. It will also be necessary to adapt the markets, regulatory framework and infrastructure. Chaired by Eberhard Umbach, this Working Group analyses development paths for closer coupling of the electricity, heating and transport sectors.

The decisions we take today will have a major influence on the development of our future energy system. In the transport sector, for example, although the existing service station network could also sell biofuels and synthetic petrol, electric cars and fuel cell vehicles will need a completely new infrastructure to supply them with electricity or hydrogen. A system geared towards just one of these technologies would create path dependencies that could be difficult to overcome at a later date. Against this backdrop, the Working Group is drafting a position paper that will outline strategies for tackling these difficult decisions in order to help the relevant actors to address path dependencies and shape the future of the transport sector.

A collapse of the energy supply system would threaten both the economy and society as a whole. The energy system should therefore be as robust as possible, ideally even “learning” from disruption so that it is better prepared to cope with future incidents. How can we ensure a secure energy supply even when several unforeseen events occur simultaneously? And how does the energy transition affect the robustness of the system? A study produced by the Working Group describes a number of illustrative “threat scenarios”. The resulting position paper contains measures for a resilient energy system of the future.

It will not be possible to achieve an overall reduction in energy consumption unless private consumers start using less energy. However, high electricity bills very rarely induce people to actively change their energy consumption patterns. Drawing on findings from the field of behavioural science, this Working Group has studied a range of issues including the incentives that could be successfully deployed to encourage private households to save energy.

The energy transition is affecting demand for raw materials. With coal, oil and gas consumption expected to fall in the long term, bioenergy can help to offset the fluctuating supply of wind and solar power. However, the expansion of our renewable energy plants, storage systems and grids is causing a rise in demand for metals. This Working Group studied ways of reducing Germany’s dependence on raw material imports, along with measures to help secure our long-term energy supply.

Since energy scenarios frequently inform policymaking, it is particularly important that their results should be transparent and verifiable. However, many of the organisations tasked with producing energy scenarios do not disclose their simulation models. Moreover, it can sometimes be hard to determine whether conditions stipulated by the commissioning organisation have affected the results. In order to promote greater transparency, this Working Group developed a series of guidelines for working with energy scenarios.

The power generated by wind and photovoltaic plants fluctuates depending on the weather. In order to compensate for these fluctuations, it is necessary to develop technologies that support flexibility – we need flexible dispatchable power plants, storage systems, and demand-side management that achieves a balance between supply and demand. The challenge is to identify technologies that combine stability with sustainability, cost-effectiveness and social acceptability. This Working Group compared around 130 system configurations using its own simulation model.

In order to mitigate global warming, it is vital that as many countries as possible should make their energy supply systems more sustainable. Closer coordination of Germany’s energy transition measures and European energy and climate policy can contribute to this goal. This Working Group identified the requirements for an internationally compatible European model, focusing in particular on the European emissions trading system, the promotion of renewable energy and the EU’s internal electricity market.

Every year, the joint academy project ESYS holds its annual conference Energie.System.Wende. (Energy.System.Transition, link to German web site) in Berlin. Panel discussions and workshops provide an opportunity to present the project’s ideas and results and discuss them with interested parties from different industries and disciplines.

The Energiewende Research Forum (link to German web site) is a transdisciplinary dialogue platform. Its plenary brings together actors from government, academia, industry and civil society to discuss policy options in the field of energy research and policy. The plenary meetings are organised by the management committee (Leitungskollegium).

The joint academy project “Energy Systems of the Future” (ESYS) is a partner of the HUMBOLDT-VIADRINA Governance Platform. In the Trialogues on the energy transition (link to German web site), ESYS experts engage in discussions with actors from government, industry and civil society organisations. These one-day meetings serve to explore different perspectives on the topics addressed by ESYS and to highlight the social dimension of the relevant issues.

The ESYS Working Groups organise workshops and expert discussions (link to German web site) in order to draw on the practical expertise of energy policy actors. The WGs invite between 10 and 15 experts from academia, government, industry and civil society organisations to discuss their interim results.

Approximately once a year, the project members come together at the Harnack House in Berlin for the ESYS conference (link to German web site), where they discuss the ongoing development of the project’s themes and priorities. The current working groups also present their interim results to the conference.
