Feed-In Management
The feed-in management, commonly referred to as Eisman or Einsman, refers to the targeted control of electricity feed-in from renewable energy sources, particularly from photovoltaic systems, into the public electricity grid.
Purpose: The primary goal of feed-in management is to ensure the stability and security of the electricity grid. Fluctuating feed-in from renewable energies, which may depend on factors like sunlight, can lead to grid overloads or underloads. Feed-in management is intended to cushion these fluctuations and maintain a balanced grid.
Procedure: Grid operators are authorized to temporarily reduce or completely interrupt the feed-in from renewable energy plants in the event of impending grid bottlenecks. This is usually done remotely through appropriate interfaces on the plants. Plant operators are typically informed in advance about possible feed-in limitations.
Reasons for Feed-in Management:
- Grid Overload: When too much electricity is fed into the grid, it can lead to overheating of lines or the tripping of fuses.
- Grid Fluctuations: Fluctuations in grid frequency can cause disruptions in electricity supply.
- Protection of Plants: Feed-in management can also protect the plants themselves from damage.
Impacts:
- Loss of Revenue: For plant operators, feed-in management usually means a loss of revenue, as the generated electricity cannot be fully fed into the grid.
- Compensations: Legal regulations have been established to compensate the operators of renewable energy plants for their revenue losses. The amount of compensation is determined by various factors, such as the duration of feed-in limitations and the installed capacity of the plant.
