Cost, Performance and Maturity of Electricity Storage Technologies

COURSE NO: R05-002
Cost, Performance and Maturity of Electricity Storage Technologies
Course Highlights

This online engineering PDH course discusses the cost, performance and maturity of electricity storage technologies, with much of the discussion focusing on recent developments in battery technology.


The sections of the course are organized by technology and provide a snapshot of the status, trends in deployment, data sheets on performance, and design features. Estimates of life-cycle costs for each technology are also provided, along with the key assumptions used. Emerging technologies still in the early research and development stage are noted in the last section of the course but are not reviewed in detail.


In general, electricity storage technologies can be classified by the power they can deliver and the time required delivering it.  Thus compressed air energy storage and pumped hydro are capable of discharge times in tens of hours with power ratings reaching 1000 MW. In contrast to these large sizes, flywheels and batteries cluster in the lower end of the discharge duration spectrum, ranging from a few seconds to 6 hours.


This 5 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.

Course Quiz

Once you complete your course review, you need to take a multiple-choice quiz consisting of thirty (30) questions to earn 5 PDH credits. The quiz will be based on this publication.

The minimum passing score is 70%. There is no time limit on the quiz, and you can take it multiple times until you pass at no additional cost.
Certificate of Completion

Upon successful completion of the quiz, print your Certificate of Completion instantly. (Note: if you are paying by check or money order, you will be able to print it after we receive your payment.) For your convenience, we will also email it to you. Please note that you can log in to your account at any time to access and print your Certificate of Completion.
