| Oct 14, 2013 at 15:25 | comment | added | Lord Loh. | I have my doubts about PFC and savings to the customer. It appears to me that better PFC saves the Power Cos a lot of money. The Power Cos can bill the customers for Watts and not the VA (reactive power sent back). Unless the Co is fining for poor power factor, the customer seems to have no incentive to correct it. Do I have my facts wrong? Does PFC benefit the customer financially or otherwise? | |

| Oct 14, 2013 at 9:13 | comment | added | user36129 | @DougMcClean ah, thanks for the wiki, I was wrong then. I guess I had the wrong statistic in my head. Also, MSalters, there is no real leading or trailing phase shift as a cause of residential power factor as most of the distortion (which would be a better term) is from switching power supplies, not from phase-shifted loads. | |
| Oct 14, 2013 at 8:57 | comment | added | MSalters | I'd also expect the residential power factors to be partially leading, partially trailing, and most certainly uncorrelated. | |
| Oct 14, 2013 at 7:07 | comment | added | Doug McClean | Is that really true, @user36129 ? Wikipedia says that in 2008, 36.2% of electrical energy consumption in the US was residential. en.wikipedia.org/wiki/… (I agree with your broader point that it probably isn't worth the administrative costs.) | |
| Oct 14, 2013 at 6:07 | comment | added | user36129 | Also, kind of implied in this answer: households don't make up any kind of significant part of the electrical power consumption on the large scale. Household lighting has a sub-single digit percentage and even in summertime when everybody's home with the AC on, household power consumption is still usually below 10%. And it's distributed among orders of magnitude more users. Administrating that many users for so little potential gain is deemed just not worth it. | |
