abstract:
germany is rather experienced and still forward stepping towards the the energy transition, in german named “energiewende”. especially solar and wind power (together with other green renewables) come up with a share of nearly 38% of the electricity production in germany. this success is a “public” one in the meaning, that many private individuals, citizens, farmers, companies, organisations and others have the ownership of renewable energy installations by more than 50%. many cities and some industrial distributors form a virtual power plant by its own, collecting and distributing renewable electricity in a smart way.
nevertheless these specific solutions are far away from the status of forming a smart grid with all its interdependencies, even not regionally. so, the german government started a new approach forming “real” smart grids with its new supporting program, named smart energy showcases” (sinteg). one of the chosen projects is placed in the north-west of germany. it name is enera, which means “energy area” and which is co-ordinated by the medium-sized energy distributor ewe (in my home city oldenburg). it has a volume of 200 million euros, of which about 80 companies and industrial partners bear the main part of 140 million euros.
in the model region are living about 400 000 people (200 000 households); their share of renewable electricity is more than 170%. this region and the connected enera-project are treated as a blueprint for the energy transition process in whole germany. this project is a high demanding thread.
enera demonstrates how energy infrastructure can be innovated to provide great resilience despite the new requirements and the wide range of technologies used simultaneously. furthermore, enera demonstrates how markets and digitalization reduces grid expansion costs considerably and provides opportunities for innovative business models. enera consists of the three core categories: grid, market, data.
what are the integral parts and tasks of this project?
the answer will partly be given in this lecture.
