I'm not sure how much of a problem this will be. Most commercial/industrial
buildings use tubular fluorescents and/or high pressure sodium lights which
save far more energy than CFLs so there's no incentive (nor mandate) to
switch to CFLs. (Changing from magnetic to electronic ballasts may be a
problem but I don't know how prevalent this is.)

As lighting is only 9% of residential energy use, even changing to 100%
CFL/LED with SMPS may not be a major problem. Electic rates already embed
charges for residential power factor issues (rather than use demand
metering). It's likely that the utilities will merely ask for rate increases
to compensate for their increased costs related to harmonics.
