The request model dictates how and from whom the control signal is transmitted to us as the direct marketer under the Redispatch 2.0 measures at the plant. There are two distinct request models: tolerance-based and demand-based.
Tolerance-based The instructing grid operator sends the control signal and executes the control Works in the same way as the feed-in management procedure Grid operator and its technology is responsible for implementation Demand-based  The instructing grid operator sends the control signal to the EIV and asks the EIV to execute the control  The EIV and the control technology available to him/her is responsible for the technical implementation The tolerance-based model will be used as the standard request model. The demand-based model can be implemented if necessary for technical reasons.
