There are various measures:
Redispatching: Reducing and increasing electricity feed-in from power plants according to a contractual arrangement with a network operator or with a statutory obligation towards the network operator with reimbursement of costs
Reserve power plants: Deployment of reserve power plant capacity to compensate for a deficit of redispatch capacity according to a contractual arrangement with costs being reimbursed
Feed-in management: Curtailment of energy fed into the grid from renewable sources and combined heat and power plants at the network operator's request with reimbursement of costs.
Adjustment measures: Adjustments of feed-in and/or offtake of electricity at the network operator's request without compensation for costs if the other measures are insufficient.
The network operators are obliged, without undue delay, to inform the regulatory authority of the reasons for the adjustments and measures that were implemented.
