What is this Pass-Through Charge on my first invoice?
The Pass-Through charges you may see, typically on a first invoice are normally the connection fees from the local metering company. If you select a new move in when you enroll (where you are allowed to select your own service start date), you are requesting that the local metering company send out a representative on that day to read the meter and switch it on if needed. The Pass Through Charge is the fee that the metering company charges you for sending out that representative outside of the normal monthly schedule.
