<br />Eleqtric utilities west of the Rocky Mountains are
<br />interconnected in a large synchronous power supply network,
<br />
<br />..;
<br />
<br />,
<br />supplying power in all or part of 14 states.
<br />
<br />Planning for
<br />
<br />
<br />power supply facilities west of the Rocky Mountains is
<br />
<br />coordinated by the WSCC.
<br />
<br />In the fall of 1976 a direct current facility in
<br />
<br />western Nebraska was placed in service.
<br />
<br />This equipment
<br />
<br />will allow the routine transfer of 110 megawatts of electric
<br />power between WSCC and systems in the eastern part of the
<br />
<br />United S1}ates.
<br />
<br />This is not a significant amount of capacity
<br />
<br />>..
<br />t~
<br />
<br />
<br />for the WSCC area, in view of the long transmission distances
<br />
<br />involved;
<br />
<br />The installation of the direct current inter-
<br />
<br />connection was decided upon because technical and reliability
<br />
<br />considerations currently prohibit synchronous alternating
<br />current interconnections.
