Are there any advantages to applying PFC to individual homes? Is seems to me that the only advantage would be to the power company.

Hello regulatorcontrolrepair

Welcome to the forum.

This question has been discussed a number of times, and while there are some who are strongly of the opinion that power factor correction will save KWHrs, I can not see any foundation for that belief other than snake oil marketing.

Power factor correction reduces the inductive reactive current provided that it is correctly applied. This can reduce the current drawn from the supply, but it will not alter the KW consumed. As most domestic metering and charging is based on KWHrs, there will be no reduction in the power bill even if the current is reduced.
Unfortunately, there are many who promote the reduction in current as being a reduction in power therefore a reduction in bill. - Not true.

The only winner is the power company.

Best regards,
