A provision in a rate schedule stating that a customer's bill cannot fall below a specified level. For example, the electric energy charge may be 6.4 cents per kilowatt-hour (kWh), the customer charge may be $4, with a minimum monthly charge equal to the customer charge. In this case, a customer would be billed for $4 if usage were anywhere between zero and 62 kWh. However, even though the minimum charge may be stated in terms of a customer charge, a minimum charge differs from a customer charge in that charges for energy consumed are added to a customer charge, whereas a minimum charge ensures that the bill for energy consumed does not fall below a certain amount, even if little or no energy is consumed. A minimum charge is similar to a customer charge because it is designed to recover fixed costs of services such as meter reading, billing and facilities maintenance. Although this charge does not generally recover the full cost of these services, it does give the customer a price signal that these costs do exist.

The total of all the payments a customer will owe for electric services, regardless of how much electricity the customer uses during a billing period. Generally, it is the total of all customer service charges, demand charges, and any other fees that are assessed regardless of the amount of energy used during any one billing period.

The lowest amount which applies to the transport of a consignment, irrespective of weight or volume.

The lowest rate applicable on each type of cargo service no matter how small the shipment.

The lowest charge for which a shipment will be handled after discount and/or adjustment.

The lowest charge that can be applied to transporting a shipment.

The lowest charge that can be assessed to transport a shipment. Molar Volume The volume occupied by one molecular mass in grammes (g mole) under specific conditions. For an ideal gas at standard temperature and pressure it is 0.0224 mVg mole. Mole The mass that is numerically equal to the molecular mass. It is most frequently expressed as the gram molecular mass (g mole) but may also be expressed in other mass units, i.e. kg mole. At the same pressure and temperature the volume of one mole is the same for all perfect gases. It is practical to assume that petroleum gases are "perfect" gases. Mole Fraction The number of moles of any component in a mixture divided by the total number of moles in the mixture (see 2.17).

The least amount of freight and/or accessorial charges Estes will bill the customer.

The lowest charge that can be assessed to transport a shipment, sometimes referred to as the "Absolute Minimum."

The lowest amount that will be charged regardless of the amount of service rendered.
