1.0 INTRODUCTION The Annex Creek and Sa 1 mon Creek watersheds are located ; n the mounta i nous areas outs 1 de of downtown Juneau, Alaska. The bas ins typi ca 11 y receive over 100 inches of precipitation annually, largely as snow at higher elevations. The ma in source of energy and capac i ty for the Juneau area ; s the Snettisham Hydroelectric Project, which is operated by the Alaska Power Administration, an agency of the U.S. Government. The area is served by two electric utilities, the Applicant and the Glacier Highway Electric Association (GHEA), a rural electric cooperative with preference status in obtaining wholesale power from Federal sources. The GHEA currently serves about 8% of the tota 1 Juneau area load. The App 1 i cant uses its hydroe 1 ectr i c fac i 1 i ti es at Annex Creek and Salmon Creek to displace more expensive diesel generation. The expected average annual generation of the Project is estimated to be 55. 7 GHh, wh i ch is proj ected to meet approx i ma te 1 y 25% of Juneau I s energy demand in 1985. The Annex Creek Powerhouse has a rated capacity of 4,050 kVA, and contributes 43% of the total Project energy. The Salmon Creek Lower Powerhouse wi 11 contri bute 57% of the tota 1 Project energy. Both components are operated to maximize generation during the peak winter load months of December through April. The Salmon Creek Upper Powerhouse has a rated capaci ty of 3,500 kVA. Because the same penstock serves both the Upper and Lower powerhouses, they cannot be operated simultaneously. This exhibit identifies and discusses the information related to the present Proj ect operati on, energy and capac i ty, and the need for and use of Proj ect power. Sa 1 mon Creek Reservoi r 1 eve 1 rna i ntenance procedures wi th regard to dam safety are also discussed. As in the other Exhibits of this app 1 i ca ti on for new 1 i cense, because the Project inc 1 udes more than one dam with associated facilities, each dam and the associated component parts are described together as a discrete component. The Annex Creek Component is discussed first, followed by the Salmon Creek Component.
