not .intend to enter into power purchase commitments outside the range of alternatives
studied in the EPM-EIS.

Western cannot establish the appropriate level of environmental documentation and public
review for resource acquisitions to meet long-term finn-power commitments until after
specific resource alternatives have been identified and SLCNIP contract terms determined.
In addition, the required NEPA documentation will depend on whether new generation or
transmission facilities will be constructed as a consequence of the replacement resources
selected.

3.3.4 ENERGY EFFICIENCY EFFORTS

As discussed above, only energy efficiency and demand management directly under
Federal control (Western and possibly Reclamation) will be considered in the Replacement
Resources Process. Western intends to pursue increased energy efficiency on loads and
facilities within its control as a part of replacing unavailable capacity at GCD. Energy
efficiency programs relevant to the Replacement Resources Process will be those programs
where Western is able to decrease the energy and/or capacity requirements through
increased system efficiency.

These programs may include transmission . line/substation efficiency improvements, such
as:

· upgrading voltage of existing lines to reduce losses;

· reconductoring existing lines to reduce system losses;

· constructing new transmission lines that reduce system losses;

· replacing power transformers with lower loss types;

· reconductoring substation bus that has marginal capacity;

· reducing station service loads/more efficient station equipment;

· increasing dispatch efficiency to increase available energy during peak periods;

· applying peak-shifting to selected substation loads (HVAC, battery chargers);
and

· modifying maintenance building lighting, HVAC, insulation.

Western will also continue to examine and implement programs which decrease Western's
dependence on energy. For example, improvements may be proposed to Western's office.
buildings and communications sites, such as:

· modifYing building Iighting/HVAC/insulation;

· applying peak-shifting to selected loads;

· procuring more efficient office equipment (Energy Star, etc.); and .
