German Electricity Market in 2017 – records for battery storage and redispatch

TenneT published its market report for Germany and the Netherlands and provides some very interesting insights:  While wholesale prices increased, power plant operators were facing decreasing revenues close or below zero. The first tenders for renewable generation reached low subsidy-levels below 7€cent/kWh and the market utility-scale battery storage seemed to take-off, but remains a rather small market for now.

While this is currently a primary task of the transmission system operator, the distributed character of the energy transition requires a more decentralized approach. Now, the question how to organize the TSO-DSO coordination efficiently becomes a very important issue.
