Future of Energy Supply in the Capital Region


Energy Transition

The "German Energiewende" initiated a transformation process which aims to lead our current energy system based on fossil fuels towards a sustainable system relying on renewable energy sources.

It is against this backdrop, where politics, economy and science come together, that we are working on solutions for the "energy supply of the future".

Climate Protection

Among other goals the energy concept of the Federal Government aims for the following: By 2050 at least 80 percent reduction of greenhouse gas emissions from what they were in 1990. By the same time renewable energies are to account for 60 percent of the gross final energy consumption. Electricity generated from renewable energy sources is to account for 80 percent of gross electricity consumption in 2050. Primary energy consumption is to be 50 percent lower than in 2008 and the electricity consumption is to be cut by 25 percent. In the transport sector, final energy consumption is to fall by about 40 percent, the baseline in this case being 2005. The German Goverment´s Climate Action Programm 2020


According to the Federal Government the year 2020 will see 1 million e-cars on Germany’s roads. Reality check: As of 2015 a total of 18.948 e-cars and 107.745 hybrids have been registered according to national vehicle register (Source) now. What about the capital region? Nearly 1.200 e-cars are registered in Berlin and Brandenburg, as well as close to 11.000 hybrids. When it comes to the charging infrastructure in both states, the Berlin Agency for Electromobility (eMO), estimates that there are 300 public charging stations as of now. Vision 2020


In some of the grid areas in Brandenburg the amount of energy coming from renewable sources already accounts for 100 percent. However, this doesn’t lead to a full supply but to days with extreme regenerative overproduction and to days when no ‘green energy‘ is generated at all. The task of balancing an increasing energy supply from renewable – weather dependent – sources with a fluctuating demand, becomes more complex, thus creating new challenges for the energy distribution network.

In the last 20 years

the amount of regenerative power generation has increased rapidly. In 2014, it accounted for 27,4 percent of the gross electricity consumption in Germany. The development of these renewable generation capacities took place very differently, depending on the region. It was also undertaken isolated from the local energy consumption and regardless of the transmission capacities of the grids.

Nearly every day

conventional and regenerative generators in Brandenburg have to be slowed or even shut down ("forced interventions") in order to stabilize and relieve the local grids. This is caused by high regenerative feed-ins on one hand and low consumption on the other.

Just a few seconds

normally remain for the personnel at the grid control center to decide if, when and where conventional and regenerative generators have to be slowed or even shut down. The worst-case scenario involves a black-out.

Solution Smart Grid?

A so-called “smart grid” is formed by improving conventional grid infrastructure with an innovative information and communication technology. With the help of a smart grid, it is possible to manage a growing amount of decentralized power generators, storages and consumers. Smart Grids and Meters (EU Comission)

Project Details

What we do

In our project we are showing where and when regenerative surplus energy occurs in the capital region. We have also set up a smart grid in which electro mobility is integrated as well. Thus, we are able to demonstrate the “future of energy supply”.

Our smart grid

is located on the central campus of the Brandenburg University of Technology (BTU) Cottbus-Senftenberg in Cottbus. A photovoltaic station and a combined heat and power plant (CHP) are used as generators within the smart grid. A stationary batter, several e-cars, a Power-to-Heat (P2H) and a Power-to-Gas (P2G) installation serve as controllable loads. Detailed info on smart grid (PDF)

Part of a nationwide strategy

In 2012, the Federal Government selected four regions to become part of the nationwide promotional program called “Electromobility showcase”. Here, the economic and academic sectors of each region were to exhibit their capacity in this field.

The states of Baden-Württemberg, Niedersachsen, Bavaria and Saxony as well a Berlin and Brandenburg (“the capital region”) became part of the initiative. The latter two formed the “Berlin-Brandenburg International Showcase for Electromobility” which consists of 30 chore projects, 257 partners and is coordinated by the “Berlin Agency for Electromobility” (eMO).

In 2013, SMART Capital Region, one of the chore projects of the Berlin-Brandenburg showcase was started. It is 100 percent funded by the government of Brandenburg (Ministry for Economic Affairs and Energy, MWE) and will terminate at the end of 2016.

We are charging bidirectional!

Bidirectional charging means that vehicles are capable of feeding energy back into the grid if needed. By doing so, they turn into ‘rolling energy storages‘. With our present technology we successfully have demonstrated this important stage concerning the evolution of electro mobility, thus positioning ourselves within this field of research.


Our smart grid is set up in close proximity to our ‘Visitors Center Smart Energy Grids‘ (German short version ‘BIENe‘). People who are interested in our work can explore its different components by following a ‘tour of signs‘ that is set up around BIENe. At the visitors center itself, we welcome diverse groups while facilitating workshops and other events. Here, a time line gives an insight into the development of electro mobility in general and the electrical power supply in the capital region. It’s definitely worth a visit!


Electro mobility in Germany

“In the next years we will see a slowly but growing number of plug-in hybrids on Germanys roads. The routes that can be covered by electric drive will also increase up to 60 km. The main car manufacturers already sell battery-electric vehicles with a slowly increasing battery capacity. Different concept cars have been introduced with battery capacities that range from 350 to 500 km. These cars will be available in the upcoming years.”

Energy distribution in Germany

„An enormous expansion und modification of the power grids has become necessary but due to local resistance this process is only very slowly moving forward. A growing amount of cabling is economically disadvantageous due to its high costs. From a ‘power supply operational‘-point of view, it also has to be considered difficult. However, regenerative generation will grow further and will keep on increasing beyond the peak load. Conventional generation will be continuingly forced out of the market but has to be kept connected to the grid in order to serve as a ‘spare capacity‘ in times with no regenerative feed-ins. This ‘stand-by-modus‘ is to be financed through the electricity price itself.”

Prof. Dr.-Ing. Harald Schwarz

Energy region Brandenburg

„From an academic perspective Brandenburg serves as an excellent ‘real-time laboratory‘ to research the interactions of different players in the energy sector. It’s a state in which conventional and regenerative generation are equally high. To add to that, the amount of regenerative energy in its grids already covers 100 percent of the power consumption. Around here we are facing a situation of what reality will look like in the rest of Germany in about 30 years from now.”

Prof. Dr.-Ing. Harald Schwarz

Beyond SCR

“As part of the ‘Berlin-Brandenburg National Showcase for Electromobility‘, SCR has contributed to research the future situation within the last three years. The projects topic will be further developed and thus will continue as part of the program ‘Showcase Smart Energy – Digital Agenda for the Energy Transition” of the Federal Ministry of Economic Affairs and Energy until 2020.”
