"Integration into the national grid of onshore and offshore wind energy generated in Germany by the year 2020"

The final version of the dena study “Integration into the national grid of onshore and offshore wind energy generated in Germany by the year 2020” (dena Grid Study I) commissioned by the Deutsche Energie-Agentur (dena) was presented to the general public in February 2005. The steps necessary to integrate power production, especially from wind systems, into the electricity supply system can now be examined in this completed study of over 500 pages.

The results of the study show, that the Federal Government's planned goal of a share of at least 20 percent of renewable energy in power generation in Germany between 2015 and 2020 is achievable. However, the precondition for this is the implementation of the measures shown in the study with regard to the onward development of the power supply system. On this basis, the study addresses these most important points:

  • Approximately 400 km of the existing 380 kV grid has to be upgraded; approximately 850 km new construction is needed
  • Reliable energy supplies on today's standards can be guaranteed if certain technical measures are implemented
  • Approximately 20 to 40 million tons CO2 emissions can be avoided in 2015 according to the structure of the power plans in operation then
  • Additional costs for the expansion of wind energy will cost private households between 0.39 and 0.49 Cent € per kWh in 2015.
