Aren't normal customers, i.e. consumers, only billed by kWhr? I thought it's only the large industrial users that had to monitor their power factor and stay under a certain value.
If so, reducing powerfactor will not reduce your powerbill. I.e. scam.
And what if you load the net capacitively (instead of inductively, like with motors) already? Then adding more caps would only worsen the situation.
