AGENDA TITLE: Directthe City Managerto Researchand Recommenda Leveling Mechanismfor
the Energy Cost Adjustment (ECA) and, in the Interim, to Implement a Maximum
Levelforthe ECAof $0.025 per Kilowatt-hour Beginning in February2009, (EUD)
MEETING DATE: January 21,2009
PREPARED BY Electric Utility Director
RECOMMENDED ACTION: Direct the City Managerto research and recommend a leveling
mechanism for the Energy Cost Adjustment (ECA) and, i n the
interim, to implement a maximum "cap" for the ECA of $0.025 per
kilowatt-hour beginning in February2009.
BACKGROUND INFORMATION: In August 2007, the Electric Utility Department began
implementation of a monthly Energy Cost Adjustment to ensure that
the utility neither under- or over -collected power costs on a current
basis. Each month, EUD's power costs are compared with the amount of power costs included in base
electric rates ($0.0831 per kilowatt-hour)—the difference becomes the ECA for that month.
In the eighteen months that the ECA has been in effect, the monthly ECA level has ranged from a
negative $0.0125 (credit) to a positive $0.0464 (charge). The average has been $0.0157. When the ECA
was formulated, it was anticipated that its range would be relatively small with the highest level being in
winter months (when overall electric bills are relatively low) of perhaps $0.030 per kilowatt-hour.
For the first sixteen months, the peak ECA level was $0.028 however the ECA has exceeded $0.045 for
the past two months (December2008 and January 2009) in large part due to overall budgeted power
costs being higherthis fiscal year ($46.7 million) as compared to the priorfiscal year ($42.3 million).
Consequently, it is recommended that a "cap" be implementedfor the ECA of $0.025 per kilowatt-hour
beginning in February 2009. Power Supply costs that are not recovered in any particular month because
of the cap will be rolled over to the next month for inclusion in the ECA calculation. Staff will continue its
review of smoothing mechanisms for the ECA for future presentation to the City Council by the City
Manager. From a typical electric customer standpoint, the proposed ECA cap will move the recovery of a
portion of power supply costs from higher cost winter/summer months into lower bill months in the spring
and fall.
FISCAL IMPACT: The recommended ECA cap is expected to have a relatively nominal (and short
term) impact on the utility's cash flow and reserve levelal

"ECA"

What'is an ECA?
• An ECA is a mechanism to collect/credit purchase power
and/or fuel costs on a regular basis
• "ECA"s are called a variety of different names across the
country (i.e. FCA, PCA, etc.)
• Timeframes of adjustment run from monthly to quarterly
to semi-annually to annually
The types of charges included in an ECA run the gamut
from all power supply costs, variable costs only, fuel
only, purchased power only, etc.

California Public Power Credits Are Adapting
To An Evolving Market
Publication date: December 18, 2006
"On the financial side, many utilities that lacked fuel or power cost
adjustments five or 10 years ago have now established them. These
adjustments allow for quicker and more complete recovery of
variable power and fuel supply costs, while at the same time
reducing some of the politics that can limit or delay cost recovery.
We believe utilities that have yet to implement some version of a
variable cost recovery mechanism in their rate structures should
certainly consider them, especially those that are gas -dependent, as
these mechanisms can help to stabilize financial performance and
debt service coverage ratios --two key factors in our credit analysis."
Excerpt
CI
Lodi ECA
• Equals amount of power supply cost different from
8.31 0/kwh
• Energy Cost Adjustment (ECA) updated monthly to
reflect actual EUD costs
• Adjustment for variations in actual vs. projected sales
on a two month lag
• ECA could reflect a char a during periods where costs
are higher than "base" level ora credit when costs are
lower than base level
• ECA identical for all rate classes
• Simple and transparent
• Readily trackable/auditable

*Plus adjustment for over/under collection two months prior.
ECA Variability
Generally market power prices higher in
summer and winter (hence higher ECA)
Seattle City Light Exchange
— Reduces power cost in summer months
— Increases power cost in winter months
N
Issue
• The ECA has exceeded the upper end of the
range we anticipated.
• Winter months of December through
February the ECA will exceed 30/kwh.
• Primary reasons include:
— Seattle energy payback
— Increased fixed NCPA plant expenses
— Higher open market power costs than
prior year

Recommendation
• Limit ECA to a level of 2.5¢ per kwh
• Roll any "excess" power costs to
subsequent month(s)
• Continue exploring other practical ECA
smoothing scenarios
• Return to City Council with a report and
recommendations
