1.0 INTRODUCTION The Annex Creek and Salmon Creek Hydroelectric Project (Project) is located in Southeast Alaska i~ a mountainous region within the City and Borough of Juneau (CBJ). The Project consists of two geographically separate components, Annex Creek and Salmon Creek, whose reservoirs are located approximately 10 miles northeast and 3 miles north of downtown Juneau, respectively. Total Project installed capacity is 18,050 kVA (13.1 MW). The Annex Creek Powerhouse contains two turbine-generator units for a total capacity of 4,050 kVA (3.6 MH) and is located 11 m; 1es east of downtown Juneau on Taku Inlet. The Salmon Creek Upper Powerhouse contains two turbine-generator units for a total capacity of 3,500 kVA (2.8 MW) and the Lower Powerhouse contains one turbine-generator unit rated at 10,500 kVA (6.7 MH>' Due to constraints on the Salmon Creek Upper Penstock, both powerhouses cannot be operated simultaneously. Both are located within the Juneau Townsite which is shown in Exhibit G-l. The existing facilities are described in detail in the following sections and their locations are shown in Exhibit G-1. Since the Project consists of two distinct reservoir components with associated facilities, each reservoir and its associated facilities are described as a discrete development (Component). The Annex Creek Component is described first, followed by Salmon Creek. The Project is owned and operated by Alaska E1 ectri c Light and Power Company (AELP). AELP is an investor-owned electric utility that serves approximately 901 of the population of CBJ. It is estimated that the Project wi 11 supp 1 y a quarter of Juneau IS e 1 ectr i ca 1 energy dur i ng 1985. A br i ef history of AELP and the Project is presented below. AELP was organized in 1893, and in the summer of 1894 began to genera te and dis tr i bute e 1 ectri city produced from the waters of Gold Creek to res i dences and sma 11 bus i nes ses . As Juneau grew, the use of e 1 ectr i city increased, and steam generation facilities were added to the system. The mi n i ng compan i es in the Juneau area a 1 so bu i 1 t the i r own pr iva te genera t i ng facilities, most of which were hydroelectric. In 1914-15 the Gastineau Mining Company constructed first the Sa 1 mon Creek and then the Annex Creek Proj ect fac il i ties. The Proj ec't IS construction history, including the numerous rehabilitation programs, is described fully in Exhibit C. By 1936 all the mining companies and their electric generating facilities had been amalgamated into the Alaska Juneau Mining Company (A-J Industries). As AELP's load continued to grow, it met its addi tiona 1 energy requi rement wi th purchases from A-J Industri es. When the m; nes were permanent 1 y closed in 1944, AELP became the sole purchaser of A-J Industries' hydroelectric energy. Beginning in the late 1960's, A-J Industries, the Alaska Public utilities Commission (APUC), and the Juneau municipal government became i nvo 1 ved ina cos t 1 Y and pro longed 1 ega 1 dispute over the eff; c; ency of A-J Industries' hydroelectric operation and its rate base. The case went to the Alaska Supreme Court and resulted in numerous changes in wholesale rates to
A-2 AELP and, consequently, to AELP's customers. In 1973, AELP purchased A-J Industries' hydroelectric generating facilities and transmission system, and the l.awsuit was resolved. This acquisition included the existing Project facilities. An historical chronology of Project licensing events is included as Appendix A-l.
