A commercial electricity bill is made up of supply charges (the electricity itself) and delivery charges (moving it through the local utility system), plus other charges that vary by account, utility, and market. See supplier vs. utility charges for the full distinction.
At a high level, there is a distinction between energy supply and delivery. The supply portion covers the electricity purchased for the business. Delivery charges relate to moving electricity through the local utility system and maintaining that system. There can also be other applicable charges depending on the account, utility, market, and contract.
