Advantages of Electricity Storage to the Electric Grid

COURSE NO: R02-013
Advantages of Electricity Storage to the Electric Grid
Course Highlights

This online engineering PDH course discusses advantages to the electric grid that are gained through using electricity storage systems to supplement electrical generation systems. It presents a total of fourteen such advantages provided by an electricity storage capability, including ancillary services, grid system services and functional uses, end user/utility customer functional services, and renewables integration.


One example of an advantage is time-shifting, the purchase of electric energy when prices are low, and then storing it and using or selling the energy later when prices are high. Another example, possible only under certain grid conditions, is using energy storage to reduce the need to buy new central station generating capacity. A third example is using energy storage for grid regulation, that is, the damping of momentary differences caused by fluctuations in generation and loads. In general, the rapid-response characteristic (i.e., fast ramp rate) of most storage systems makes them especially valuable as a regulation resource.


This 2 PDH online course is intended for electric systems engineers/planners, storage system vendors, and regulators concerned with the design and implementation of stationary energy storage systems.
