APS
- 2005 Rate Case Filing
On
November 4, 2005, Arizona Public
Service Company ("APS" or "Company") filed an
application with the Arizona Corporation Commission ("ACC"
or "Commission") for a permanent rate increase. APS is seeking
an increase of $449.6 million in
base rates1
or a 21.1 percent increase on
average for the Company's
jurisdictional electric operations.
On
November 22, 2005, RUCO filed a motion to intervene
in the case.
After
discussions with ACC Staff, APS
agreed to file an amended
application containing more recent
operating information (the Company
had originally chosen a test year
ended December 31, 2004).
On
January 31, 2006, APS filed its
amended application which contains
information on a test year ended
September 30, 2005.
On
March 28, 2006, The ACC's Chief
Administrative Law Judge
("CALJ") issued a
procedural order that established
the rules for discovery and the
original filing dates for testimony.
On
March 30, 2006, RUCO filed a motion
to modify the procedural schedule.
On
April 5, 2006 the CALJ issued an
amended rate case procedural order
revising the dates set forth in the
procedural order filed on March 28,
2006.
During the
discovery phase of the proceeding (the period prior to hearing) RUCO
issued data
requests to obtain further information on APS'
application and conducted a full audit and cost of capital analysis.
ACC
Staff, RUCO and other
intervenors to the case filed
direct testimony on all issues,
except for rate design, on Friday,
August 18, 2006. RUCO's
