TDU delivery charge

Also: delivery charge, TDSP charge, wires charge

A regulated charge for transmitting and distributing electricity through the local delivery system.

What it means

Delivery charges can include fixed and usage-based components. A REP may pass them through on the retail bill, but changing the REP normally does not change the TDU assigned to the address.
