Wind and Solar Energy Curtailment: Experience and Practices in the United States
National Renewable Energy Laboratory (NREL)
[...] Curtailment is a reduction in the output of a generator from what it could otherwise produce given available resources, typically on an involuntary basis. Curtailment of generation has been a normal occurrence since the beginning of the electric power industry.

A growing concern in electric power systems is renewable energy curtailment, meaning some of this fuel-free and emissions-free energy is unusable due to a variety of factors. There are two primary drivers behind renewable energy curtailment. The first is transmission constraints where the renewable generation sometimes exceeds the capacity of the local transmission system and energy cannot be delivered to load centers. [...]. The second driver is the ability of conventional generators to vary output to accommodate renewable generation.
Tapping into the Benefits of Energy Curtailment
Embracing energy curtailment can turn your company into a flexible energy consumer, setting you up to react quickly and take advantage of changes in the energy market.
Energy Curtailment Program
In order to deliver a reliable supply of electricity to our customers, we are sometimes required to employ a variety of conservation and demand management strategies. One of these strategies is our Curtailment Program, which involves requesting certain customers reduce their load on the electricity system during the winter peak period (8 a.m. - 9 p.m. daily during December, January, February and March).
Was ist Einspeisemanagement?
Mit dem Begriff Einspeisemanagement, abgekürzt auch Eisman oder Einsman genannt, ist die vom Netzbetreiber vorgenommene Abregelung der Einspeisung von Strom aus Erneuerbaren Energien sowie KWK- und Grubengasanlagen in das Stromnetz gemeint.
