'''Load rejection''' in an [electric power system](/source/electric_power_system) is the condition in which there is a sudden [load](/source/Electrical_load) [loss](/source/Power_outage) in the system which causes the [generating equipment](/source/Electricity_generation) to be over-frequency.

A load rejection test is part of [commissioning](/source/Project_commissioning) for power systems to confirm that the system can withstand a sudden loss of load and return to normal operating conditions using its [governor](/source/Governor_(device)).<ref>{{cite web|url=http://gasturbinespower.asmedigitalcollection.asme.org/article.aspx?articleid=1688944 |title=ASME DC &#124; Journal of Engineering for Gas Turbines and Power &#124; Load Rejection Tests and Their Dynamic Simulations With a 150 kW Class Microsteam Turbine |publisher=Gasturbinespower.asmedigitalcollection.asme.org |date= |accessdate=2014-04-21}}</ref> [Load banks](/source/Load_bank) are normally used for these tests.
