Electric Rate Study Implementation Plan
September 11, 2003
Data Gathering, Modeling and Testing — (5-6 Weeks)
The purpose of this step is to (a) gather data that was not included in the Study and has been
requested by the Utility Committee and (b) develop a model that will allow the staff to validate
the impact of the proposal with respect to customer impact, competitive position, and fiscal
impact. Developing the model is the most complex part. The components of this step
include:
Revising cost comparisons/competitiveness using our PCA and theirs
Inventorying ownership of primary transformers and differences in billing
Inventorying special rate classes and contracts, and explaining rates and rationales
Building a billing model of our existing rate classes using a 20% random sample that can
be used to test the impact of the Rate Study proposals

Staff Analysis/Recommendation — (4-6 Weeks)
The purpose of this step is to allow staff to use the model developed in Step 1 to evaluate the
impacts of the rate proposals and alternative structures and combinations.
From this analysis, staff will develop recommendations that are felt to be most aligned with the
objectives, i.e., provide sufficient revenues and revenue stability to cover operating costs, five-
year CIP, and transfers; keep rates competitive with neighboring utilities; provide proper
economic signals; fair and non-discriminatory rates; easily understood; continuity of pricing.
The Study recommendations that will be evaluated will include:
Rates — structure, timing, phasing
Ratcheting
Class Shifting (cost to a customer to shift classes)
Power Factor (impact of increase power factor premium)
Power Cost Adjustment Calculation
Feasibility of Special Rate Classes
Load Management and Conservation
Cost of Implementation

Public Comment/Testing/2™ Staff Analysis (optional) - (2-4 Weeks)
This step would allow staff to do some focused meetings with customers to go over the
proposed changes in rates. This will allow staff to obtain additional advice and comments
from customers to better refine the final recommendations that would go to City Council. It
would also allow staff to gauge what support or opposition there would be before sending it to
City Council. The risk is that Council members may take their positions on proposals before
getting final recommendations.
Utility Committee Review & City Council Hearings — (4-8 Weeks)
Billing Changes and Testing — (4-8 Weeks)
It is important to note that changes in rates will require us to reprogram our billing software,
and the degree and complexity of changes will impact the cost of programming. The City will
be dependent upon HTE programmers.
Public Notice — (1 week)
