Create a functional one-line diagram using
ETAP software
Collect, research, and report economic
analysis of companies providing power to city
of Breda
Advise and educate city of Breda on alternate
sources of energy and money saving
techniques


Phase 1 development of small town model
power distribution system
Understand costs associated with small
towns in Iowa



Collect cost data for the following areas:
Generation, Transmission, Distribution, and
Regulation.
Many costs are hidden.
Once cost breakdown is complete, we’ll know
which areas we can have the greatest impact.

Generation Charges: MEAN and WAPA
Demand Charges: MEAN and Midwest ISO
Transmission Charges: MidAmerican and
Midwest ISO

IEEE Standards
Power Factor Maintenance: +/- 5% of unity.
Cost Effective Upgrades: All suggested improves must
pay for themselves in 15 years.
 Non Technical Document: All reports must be easily
understood by a non engineer (City Clerk.)

Team learning how to use ETAP
ETAP data is only as good as the model
developed
Data for model continually requiring updates
 Length of conductors
 Types of fuses
