Is any one familiar with the Peak Energy Saver from  The unit is intended to store energy from motors used in the home and then supply the stored energy back to the home, thus reducing consumption.  Clames to reduce energy consumption between 10% and 25%.   Fact or Fiction, does any one know?   

Thanks PJ Stevens

Thanks Bob.  This providing me a quick uptake on the whole issue...greatly appreciated!

You're welcome Fred. Good luck to you.

Power factor correction is old, well established technnlogy which is widely used across industry and larger electricity power users. However this technology is used to reduce wasted power measuured as Kvar to bring KVA closer to KW and is not well known industry wide to be used for the above application. Further information can be seen at
Therefore there would need to be authoritative offical independent research conducted for reliable information.

Power Factor Correction is ONLY worth considering for electricity users who are penalized (billed) for inadequate power factor by the utility. All others are billed for kW, not KVA, so it is a complete waste of money for all others to fall prey to scammers hawking power factor correction devices to homeowners and typical commercial customers.

Unfortuantely that is not the whole picture. Granted billing is in KW however improving power factor in an industrial/commercial environment will have a saving as motors will now be operating optimally hence be more efficent so last longer with less maintenance.

Because also KVA is closer to KW then any voltage optimisiation equipment will also make more savings.


Improving a building or plant's power factor does NOTHING for individual motors. I sincerely hope you are not hawking your views for personal gain.

I like your phrase horsefeathers though here in the UK we may say rockin' horse dung!.... joking aside though I can only vouch for how industrial 3phase sites are billed here, the US may be different billing. So installing PFC equipment will (a) reduce the Kvar known as the reactive charge (b) potentially reduce the availability or capacity charge and (c) reduce the load on the transformer, the I2R losses or load losses. Potentially also reduce line losses but that will depend where the capacitors are placed.

Well, I work with the conservation guys at a big local electric utility. One of them told me, by way of agreeing that residential power factor correction is a complete scam, that out of their 400,000 (yes - four hundred thousand) electric customers, only FOUR are on power factor billing.

I imagine those four are large industrial sites, such as paper mills, with access to engineers to evaluate and implement alternatives.

4 out of 400K? All 4 are most likely large industrial customers with 3 phase power. There is absolutely no reason for any residential customer to be concerned about this. I've never seen/heard of any time of PF charge on single phase power.
