Exhibit No. 1 Case Nos. AVU-E-15-05/AVU-G-15-01
S. Morris, Avista Schedule 1, p. 1 of 2
Avista Utilities provides electric and natural gas service within a 26,000 square mile area
of eastern Washington and northern Idaho1. Of the Company’s 370,194 electric and 329,722
natural gas customers (as of December 31, 2014), 127,134 and 78,061, respectively, were Idaho
customers. The Company, headquartered in Spokane, also provides natural gas distribution
service in southwestern and northeastern Oregon. A diagram of the Company’s Corporate
Structure is shown in Exhibit No. 1, Schedule 1 page 2. A map showing Avista’s electric and
natural gas service areas is provided in Exhibit No. 1, Schedule 2.
As of December 31, 2014, Avista Utilities had total assets (electric and natural gas) of
approximately $4.2 billion (on a system basis), with electric retail revenues of $758 million
(system) and natural gas retail revenues of $314 million (system). As of December 2014, the
Utility had 1,658 employees.
On June 30, 2014, the Company completed the sale of its former Ecova business unit to
Cofely USA Inc, an indirect subsidiary of GDF SUEZ, a French multinational utility company.
On July 1, 2014, the Company acquired Alaska Energy and Resources Company (AERC)
by issuing Avista common stock to the holders of AERC common stock in exchange for their
shares. AERC’s primary subsidiary is Alaska Electric Light and Power Company (AEL&P),
which provides electric service to the City and Borough of Juneau, Alaska.  
AERC became a wholly-owned corporation of Avista. AEL&P, a vertically integrated
electric utility providing electric service to the City and Borough of Juneau, continues to be a
wholly-owned corporation of AERC, operating independently of Avista Utilities. AERC and
AEL&P are separate legal entities and their debt is backed by the assets and equity of AERC and
AEL&P, and holders of their debt have no recourse against Avista. Avista does not provide
collateral or guarantees related to AERC or AEL&P debt. The debt and equity of AERC are
excluded from the capital structure proposed in Avista’s rate filings.
1 Avista also serves approximately 25 retail electric customers in western Montana.
