FOOTNOTE DATA<br />

Schedule Page: 426.14 Line No.: 19 Column: a<br />

The original entries in column f were in two decimal places, which the <strong>FERC</strong> software<br />

rounds automatically to whole numbers. The entry here is an adjustment to present the<br />

correct total.<br />

Schedule Page: 426.14 Line No.: 21 Column: a<br />

The Distribution Substation section includes substations that are characterized as<br />

Transmission based on the methodology where any substation that has a<br />

transmission-to-transmission transformation (Primary voltage >=60kV <strong>and</strong> secondary voltage<br />

>= 60kV), is defined as a transmission station, regardless of the number of distribution<br />

assets in the station. There are 600 Distribution Substations <strong>and</strong> 53 Transmission<br />

Substations with distribution transformer banks. Of the Distribution Substations, there<br />

are 462 substations with => 10 MVa capacity <strong>and</strong> 138 with < 10 MVa capacity.<br />

Schedule Page: 426.17 Line No.: 19 Column: a<br />

The original entries in column f were in two decimal places, which the <strong>FERC</strong> software<br />

rounds automatically to whole numbers. The entry here is an adjustment to present the<br />

correct total.<br />

Schedule Page: 426.17 Line No.: 21 Column: a<br />

Substation voltage classes are listed separately for each substation. Substations having<br />

combined total capacity of =>10 MVa are listed individually above. All transmission<br />

substations are =>10MVA. A number of substations contain several voltage classes on<br />

multiple lines. All transmission <strong>and</strong> distribution substations are unattended.<br />

There are 93 Transmission Substations <strong>and</strong> 600 Distribution Substations, representing a<br />

total of 693 physical transmission <strong>and</strong> distribution substations. There are 53 Transmission<br />

Substations with both transmission <strong>and</strong> distribution transformers.<br />
