Very good news for you. I am sure you will see a reduction in power usage.
A power meter is calibrated to 250V. Being that the meter is a stupid device and measures current flow thru the meter based on 250V to determine your power consumption. Any voltage below 250V means you have to use more current flow to compensate. Power =Voltage x Current. The long service drop wire causes a lot of power to be lost before it gets to your house.
