Buyer Beware

If it's too good to be true, it probably is!

 

There are many opportunities to save money by applying Power Quality solutions and many of these solutions provide energy savings and other savings opportunities beyond their primary intention but it is important to recognize some of the significantly overstated marketing claims by manufacturers. The energy savings claims are often overstated by an order of magnitude (10X) or more. 

 

The intention of this paper was not to argue the detailed technical aspects of each solution, per se, but rather to point out the pitfalls in believing the information publicized regarding these types of equipment. In addition, this paper was assembled in an attempt to show the dramatic change in sales methods for Power Quality solutions over the past several years.

Mike Holt’s Comment: EPRI (Electric Power Research Institute) is looking to evaluate "energy saving" devices. The following is of interest for the project:

• Names and information (technical specifications, marketing literature, etc.) for retrofit energy saving devices to help identifying the spectrum of technologies. 
• Technical papers that address the technology, performance, testing, and evaluation of retrofit energy saving devices. Specifically, technologies that claim energy savings.
• Site studies and test reports.

EPRI is not seeking general comments, anecdotes, or opinions about particular technologies or manufacturers. If you would like to contribute to this study, please contact Tom Geist at [TGeist@epri.com].
