Baseload

A base load power plant (or base load power station) is one that provides a steady flow of power regardless of total power demand by the grid. These plants run at all times through the year except in the case of repairs or scheduled maintenance.Power plants are designated base load based on their low cost generation, efficiency and safety at set outputs. Baseload power plants do not change production to match power consumption demands since it is always cheaper to run them rather than running higher cost combined cycle plants or combustion turbines. Typically these plants are large enough to provide a majority of the power used by a grid, making them slow to fire up and cool down. Thus, they are more effective when used continuously to cover the power baseload required by the grid.

Grundlast bezeichnet die Netzbelastung, die während eines Tages in einem Stromnetz nicht unterschritten wird. Da der niedrigste Stromverbrauch meist nachts auftritt, wird die Höhe der Grundlast bestimmt von Industrieanlagen, die nachts produzieren, Straßenbeleuchtung, und Dauerverbrauchern in Haushalt und Gewerbe. Darüber hinaus kann die Grundlast von den Energieversorgungsunternehmen noch erhöht werden, indem zu Schwachlastzeiten Pumpspeicherkraftwerke gefüllt werden oder Nachtspeicherheizungen eingeschaltet werden.
