Exhibit 27-1

How Electricity Flows To Its Users

Large-scale electric generators, such as coal plants or large wind farms, are connected to transformers that increase the electricity’s voltage, or potential energy, enabling it to be sent via transmission lines over long distances. Transmission lines carry electricity to substations equipped with transformers that decrease the voltage; from there, the low-voltage electricity is carried on distribution lines to industrial, commercial and residential customers.
