Congestion due to too much generation in the high voltage grid.

Use flexibility through NODES as an alternative to shutting down renewable in their redispatch process.
Electricity production from wind power has seen impressive growth in recent years in the Mitnetz grid area. Generation in the grid are much higher than the local consumption and congestions results in wind mills being forced to shut down. Mitnetz wanted to test buying local flexibility as an alternative to traditional means of managing this situation. Entelios, one of the leading demand response aggregators in Germany are offering local flexibility through NODES. Instead of shutting down the wind mills, the flexibility of a nearby industrial facility is activated to absorb the excess wind power. NODES brings both parties together. The project has been managed by E-Bridge, a leading German consulting firm.
In 2017, a total of 1.4 Bn Euros have been spent by the German grid operators for emergency congestion management measures, mainly due to an excess of renewable production. Together with Mitnetz and Entelios, NODES has proven that there are better alternatives. Purely market based via NODES. Cheaper and greener.
