Problem Statement

The energy and transportation demands continue to rise across the state of Iowa. An investment plan will need to be created for the next several decades to meet these demands and remain economical.

The goal of this project is to accurately describe, in a data set, the current energy and transportation sectors within the state of Iowa. This data set will be analyzed by NETPLAN, Iowa State University software, and the results will describe investment strategies as well as emission, un-served demands, capacities, arc flows, and system resiliency.

These results will be displayed on a public website. The current system as well as other scenarios will be available to the user to demonstrate different investment strategies available.

1. Investment Strategies (Cont.)

Project Implementation2. Google Earth Map

I. Acquire all needed infrastructures data for electric and transportation sectors

II. Use the geographical coordination to build KML files ( Keyhole Markup

Language) in Google Earth

III. Add the basic information (owner, size, length,…etc) for each unit to KML files

IV. Implement the KML files on the website using HTML and Java script languages

Project Implementation

Google Earth Interface Java script and HTML code Allows user to specify which

infrastructure component to view

User can view multiple components at a time (Wind speed maps and wind farm locations)

NETPLAN Results Interface Java script and HTML code 21 different scenarios available User can view the results on

the website or download them

Testing and Evaluation

18

• Test the functionality of the website to ensure all the

requirements are met

• Analyze and evaluate the base case result to ensure it is

reasonable and accurate

• Develop scenarios to compare with base case on the future

energy and transportation needs

• Evaluate each scenario for violations

Base CaseAssumptions

o Generation Investment Costs

o Transportation Investment Costs

o Lifespan

o Current Fuel Price

o Average Annual Demand

o Annual Peak Demand

o Emission Rates

o Investment Limits

o Investment Locations 19

Base CaseResults

o High wind and natural gas generation investmentso High wind potential led to feasibility of hybrid vehicleso Emissions per GW dropped significantlyo The total capacity of Iowa increased from approximately

12 GW to 30 GW

Base Case

21

Results (Cont.)

High Wind Investment ScenarioClarification: The total wind capacity we found was for use in Iowa only. If we consider the potential export of energy this number will be much higher.

This scenario represents a possible investment strategy Iowa could undertake. There have been many improvements to wind turbine technology, and this case accounts for increased capacity factor.

We found similar results to that of the base case, however wind investments now covered the capacity of the initial coal investments.

Hybrid vehicles became more feasible since more energy was being generated without an increase in generation sites. We assumed existing and new capacity factors would increase by approximately 15%.

High Wind Investment Scenario

23

Conclusion

24

• Wind is able to provide the most needed energy for the future

with the best economical and environmental solution

• Increase the wind turbine efficiency considered as the best

solution than other wind scenarios

• Investment in wind will also require investment in natural gas

• According to our analysis, hybrid vehicles should become

economically feasible sometime during the next 40 years

Future Work

• Develop and Improve NETPLAN software

• Simulation time

• End of lifespan function

• Running NETPLAN from the website

• Simulation time

• Access to CPLEX
