"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."
"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,…"
"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…"
"Unfortuantely that is not the whole picture. Granted billing is in KW however improving power factor 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…"
"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…"
"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 to bring KVA closer to KW and is not used for the above…"
"By residential solar, you mean Photo Voltaic I will assume, where the energy from the sun is converted to electric power. The conversion is to DC, direct current, for which power factor is not applicable. There is a second device, called an…"
"Unless your utility bills you for low power factor (I've not seen one that does for residential) this device will save no money. On commercial applications a simple capacitor wired across the motor leads or power line is what is used to correct…"
"It is looking like a good deal, but I am sorry to say that I do not know about this and I am curious to find more about this. Thank you for taking our attention to this. I am going to find out more and will be back here with detail information, but…"
"I did see a demo of this system recently. Classic KVAR scam. They claim now that reducing current on the neutral conductor is proof of "recycling" energy. Its a new pitch and they had a few people at their booth. It is only a new variation…"
A presentation by Greg Labbé in April 2014 on retrofitting vintage home for energy efficiency. He talked about basic building science, brick houses, movement of heat energy and moisture in and out of the house, air barrier and water barrier, house…
