• Water Supply Pro - Doc Type: Report/Study

in Chapter I, the study report will address the transmission system

necessary to util ize t'le pumped storage project; however. the Western Area

Power Administration will be respons ib Ie for the transmiss ion svstem

study, including alternative corridors. It is anticipated Hestern will

est {mate a new transmission system for. the entire region plus the specific

system needed to transmit the Dunham Point power to that network.

Past experience with pumped .storage projects 'las shown t'lat the

geology of the site is critical.

To assure that there are viable

alternatives. a geologic investigation pro~ram is scl1eduJed in the plan

formulation stage.

TI1e alternative plans for t'le proposed pOl<er plant s"ooule! be chosen in

order to assess ~he sensitivity of var.i.ous sizes to evaluation factors.

TI1e alternative plans must meet tJ,e four tests (as rlescrihed below) set

fort'l in tJ,e Principals and Standards fOT Multiple Objective Planning of

Water Resources to become candidate plans for possible selection. The

four tests are:

1. Complete In tJ,at provision is made for all necessary investments

or actions needed to assure fun TeaHzation of the p'.ans.

2. Effective in accompl_ishing tJ,e ohjectives.

3. ~fficient in acJ,ieving a given level of performance at the least

cos t.

4. Acceptable to the pub1.ic and compatible with institutional

restraints.

Selection of Preferred Plan

Once the candidate plans are identified. the planning team. "ith

assistance from the sub teams , will arraY a four account evaluation of the

sizes and recomroend a plan or plans to he investigated at tJ,e feasil,ility

'evel. Again a decision to forego the project is possil,le.
