Interview, 05 Apr 2017

Mr. Dreger, how high is China’s OFDI, and how has it been developing over the past few years? Chinese global FDI amounts to 150 billion US dollars—and it is on the rise. The flows have grown substantially since the financial crisis. China is now the second largest investor in the global ... more

Mr. Schill, what role does decentralized prosumage with solar power and battery storage currently play in Germany? The battery-supported self-generation and consumption of electricity from solar sources is still a niche in the German market. Around 50,000 storage batteries have been installed here ... more

Starting from a low level, in recent years the battery-supported self-consumption of solar electricity (solar prosumage) has grown significantly in Germany. Its growth is primarily due to the opposing trends in household electricity prices and feed-in tariffs in conjunction with government ... more

This report examines China’s strategy for investing in Europe. While investing in Western Europe is primarily about obtaining access to advanced technologies, investing in Central and Eastern Europe is more about establishing a presence in the EU common market and expanding infrastructure—which also fits into the framework of the New Silk Road Initiative. An econometric analysis reveals that the investments largely follow conventional explanatory patterns. If we distinguish between different forms of market access, the determinants become much more specific. A high industrial share, sound institutions, and unit labor costs in the target country all have a negative impact on investment in new ventures, but not on investment in existing companies. Differing investment patterns, as well as the heterogeneous interests of the EU member states, make it difficult to implement a coordinated response to the Chinese investment offensive. At the very least, however, a kind of reciprocity should be introduced within the framework of an investment protection agreement between the EU and China. This could reduce the growing skepticism surrounding Chinese investment activities.

Starting from a low level, in recent years the battery-supported self-consumption of solar electricity (solar prosumage) has grown significantly in Germany. Its growth is primarily due to the opposing trends in household electricity prices and feed-in tariffs in conjunction with government incentives for battery storage. Various benefits of solar prosumage speak to its positive potential in the German energy transformation. It takes consumer preferences into consideration, may increase general acceptance of the energy transformation—facilitating private participation in investment in the process—and relieves distribution networks. However, solar prosumage also has potential disadvantages, especially with regard to economic efficiency. Total system costs are lower if decentralized batteries are operated in a system-oriented way and if they are available for further electricity market activities, as compared to a case where distributed storage is purely focused on self-consumption. This is the finding of a model analysis carried out at DIW Berlin. It is also the reason why policymakers should focus on ensuring that photovoltaic battery systems are designed and operated to serve the overall system. Conversely, the Renewable Energy Sources Act (EEG) surcharge for solar prosumage should be abolished. In addition, models allowing tenants to generate and store their own solar electricity should not be disadvantaged, and political scenarios relevant to energy policy must take solar prosumage into adequate consideration. The political framework for photovoltaic battery storage systems must be structured in a way that minimizes undesirable effects.
