Their conclusion was that the poco may recoup savings on the pf cap due to reduced overall transformer, generator and line current loading, but an individual HO would not see any cost savings.
IIRC, a residential kilowatthour meter measures only real power consumption, and ignores reactive power (the inductive or capacitive current draw). So a homeowner won't see any difference on the electric bill. The POCOs just figure that residences have about the same power factor, and it's just figured into the rates they charge.
