Responsive - Peak Load Power Plants

Peak load power plants, also called 'peaking' or 'grid stability' power plants, feed energy to the grid every time there is a peak in power demand to be met instantaneously. Thanks to their responsiveness, very fast starting and ramping capabilities, engine power plants are highly flexible. They are perfectly well-suited to react as quickly as required by an unexpected increase of power demand or changes in weather conditions leading to a decrease of the power supplied by intermittent renewable energy sources (intermittency & flexibility challenges). Unlike traditional power plants including nuclear and coal power plants but also gas turbines, engine power plants are able to adjust power production without causing higher costs of maintenance: they are made to make up for variations.

Engine Power Plants: a Highly Responsive Technology

As shown by this graph from the Inter- national Energy (IEA), "Internal Combustion Engines" and "Internal Combustion Engines operated with a Combined steam Cycle" are highly responsive and perform particularly well in comparison with other technologies available. Engine Power Plants are able to start-up and ramp-up very quickly as well as to work efficiently with both high and low loads. Therefore they represent an optimal technology to complete the electricity provided by growing shares of intermittent renewables.
