I was just a little worried because I have heard that Dave Carlon's MegabigPower was shut down by the PUD because of harmonics issue.
PUD is a good acro for them. every so often you read unsettling things about them and their power allocation policies. Don't live there so don't really follow them. A while ago the buzz was about them actively discouraging high-power density users like data centers and mining farms - or at least ones without political clout. They claim it is 'taking advantage' of the low-cost power and takes away power availability to smaller people. Riiiiggghttt....Anywho thing is, power factor issues - and if needed, suppressing harmonics - can be addressed at the main feed from the utility using capacitors and/or reactors. Every so often you will see them on power poles, look like a bank of rectangular boxes with HV terminals. If serious enough that the utility might care it is a 1-time fix with analysis of issue and then installing the correction for it.
That makes me feel very good.
