Klondike III/Biglow Canyon Wind Integration Project
needs to respond to these requests. If BPA decides to interconnect the wind farms, BPA
needs to decide how best to integrate them into the regional transmission grid.
S.1.2 BPA's Purposes
Purposes are goals to be achieved while meeting the need for the project. These
objectives are used to evaluate alternatives proposed to meet the need. BPA will use
the following purposes to choose among the alternatives.
. Maintain transmission system reliability to industry standards;
. Act consistently with BPA's statutory obligations;
" Continue to meet BPA's contractual obligations;
. Minimize environmental impacts;
. Minimize costs; and
. Encourage development of renewable energy resources.
S.2.1 Proposed Action
BPA's Proposed Action is to: (1) enter into interconnection agreements with PPM
and PGE for their proposed wind projects; and (2) construct and operate a new double-
circuit 230-kV transmission line and ancillary facilities from the proposed wind projects to
BPA's John Day 500-kV Substation. These actions would allow the proposed wind
projects to be interconnected with the Federal Columbia River Transmission System.
The preferred route for the new BPA transmission line is the North Alternative (see
Map 1). The 12-mile long line would generally extend north from PPM's Klondike
Schoolhouse Substation for about 5.3 miles, and then west for the remaining 6.7 miles to
the John Day Substation. PPM's Klondike Ill project would be tied into the new line at
Klondike Schoolhouse Substation. The Biglow Canyon Wind Farm would connect to the
line at a new substation built by PGE located in between Klondike and the new John Day
S.2.2 Middle Alternative
The Middle Alternative would originate from the same location as the Proposed
Action (see Map 1), but would follow a different route to the new 230-kV substation. This
alternative would be about 12.5 miles long. The Middle Alternative has all the
components of the Proposed Action, but uses a different route.
