Abstract
Eagle Bluff is an environmental learning center, which has the goal to become energy self-sufficient using environmentally friendly sources. A plan to make Eagle Bluff energy self-sufficient must be reliable, cost effective and environmentally friendly. Sources of generation that will be examined to see if they meet these criteria are wind, bio-thermal, solar, and fuel cells. After all generating sources are investigated a number of plans will be developed, which use combinations of these sources. An electric layout will be designed that connects the generating sources to Eagle Bluff and to the local utility. Finally an economic analysis will be performed, which examines the investment costs and the future energy production costs. The end result will be a set ofplans, which provide for Eagle Bluffs energy needs, meet regulations, are environmentally friendly, and economically feasible.
Acknowledgment
Eagle Bluff has been very helpful in the initial consultations. They were able to identify their specific zone of interest and were more then willing to supply the necessary information for demand calculations. They provided the team with monthly electric bills going back over a year. Therefore a chart of their average and peak energy usage and demand will be produced. A chart will help view the difference in demand during different parts of year.
The clients were also very cooperative and took the team on a tour through the buildings showing their main load demands. They also showed the team the 350 KW gas powered back-up generator. This unit was installed as a back-up power supply for the learning center. Eagle Bluff uses the back-up generator during peak demands, as requested by the electric company. Currently the electric utility tells them to use it approximately once a month for 5-6 hours, resulting in a 30% discount on the electric bill.
To help estimate the load accurately, Eagle Bluff provided the team with original building blueprints. This will provide the square footage of the building area and therefore could be used to estimate lighting load, power outlets and other smaller loads. Also, Eagle Bluff initiated the collection of local wind measurements which will be provided to the team at a later date. This supplemental information should be used to estimate the possibilities of wind generation compared to the other sources such as bio-thermal or solar energy production.
The team was briefed on the facility’s bio-energy resources as a possible solution to the problem. While some facilities have been installed for turning wood into electricity, the necessary equipment such as a high efficient furnace is not in place.
Problem Statement
General Problem Statement
Eagle Bluff is a residential environmental learning center located in southeast Minnesota. Its maximum energy consumption is 500 KW. The center would like to become energy self-sufficient and remove itself from the electrical grid, except for backup purposes. The center is looking for a solution that is environmentally friendly, reliable, economically feasible and cost effective. A plan that meets these criteria should provide a number of energy sources, an electric layout, economic analysis, and a future cost analysis.
General Solution Approach
In order to provide Eagle Bluff with the required plan a variety of energy sources and storage devices will be investigated. These sources will include wind generation, hydrogen production, solar cells, fuel cells, and bio-thermal. The electric layout needs will be investigated and a proper system will be designed. All governmental and industrial regulations that apply to Eagle Bluffs situation will be investigated and the results will be reflected in any designs. At the end of the researchrecommendations will be given to Eagle Bluff on what systems they should implement according to their finances, location and the available resources. The expected end product will be a report that will include: (1) system requirements and environment, (2) options considered and descriptions, (3) prioritized options and reasons for prioritization, (4) a detailed system design and (5) economic analysis o f investment cost and future operating cost.
Operating Environment
Minnesota weather is known to range from hot to cold. Any system designed for Eagle Bluff will need to with stand wind, snow, ice, and low and high temperatures. Because of the latitude, summer daylight hours are long while winter daylight hours are short. These factors will be considered when deciding on particular types of equipment for power generation. If solar or wind are used, they will need to be placed in particular location to best optimize the sun and the wind. Using Minnesota wind demographics as well as average solar exposures for the area needs to be taken into account when providing the end result. If bio-thermal or hydrogen production are used theimpact be on the environment will need to be consideredand the local available resources will need to be examined. Due to the changing of weather conditions, whether it is seasonal or bad weather will depend on which power source they could use.
Intended Users
The plans created by the design team are intended to be used by Eagle Bluff in selecting new energy sources. The plans will allow Eagle Bluff to determine what forms and amounts of energy sources they would like to install. Also the plans will allow money to be raised to install the new generation and electrical systems. The plans will be used by potential sponsors in determining if Eagle Bluff meets the donation requirements. Visitors to the center will benefit from the implementation of the design. They will be able to view renewable resources and see energy production as it happens.
Intended Uses
Expected uses are separated into two categories:
- The project will be used to giveEagle Bluff and understanding of the possible energy solutions. Also the project will be used to determine the best plansforproducing electric energy in the most economical and environmentally friendly way.The ultimate goal of having some form of the plans implemented.
- Educational purposes. This project should increase education opportunities in the Eagle Bluff learning community and open awareness of energy conservation and clean energy production.
Assumptions
- The total power needed will not exceed 1 MW.
- The protective system used will be accepted by the local utility.
- Project should also provide reliability of the system and its actual dependency on the electrical grid.
Limitations
- Most importantly is that all of the research done by this project team will be concentrated on environmentally friendly way to produce electric energy.
- Project must include a protective system, that consists of a proven technology and applicable for Eagle Bluff.
- Project results are to be understandable to the persons not familiar with energy production and distribution. It needs to be understandable so it can be used as an educational material for students visiting the Eagle Bluff learning center.
Expected End Product and Other Deliverables
The expected end product is to deliver a set of plans that proved Eagle Bluff with a set of energy alternatives. Eagle Bluff should be able to use the plans to raise money and support for the goal of becoming energy self-sufficient. The goal of the project does not include delivering any hardware or software product to Eagle Bluff.

Proposed Approach and Statement of Work
Proposed approach
A. Functional requirements
- Meeting the demand power consumption of Eagle Bluff
The combination of power resources that Eagle Bluff can use must meet the demand needed by them to fully maintain their facility.
- Minimum impact on the environment.
Being an environmentally conscienceous place with the least amount of impact on the environment is one of their goals.
- Upgradeable system design
The design would allow the facility to upgrade the system to generate more power in regard to their needs and expansions.
- Staying connected to the electrical grid and selling any excess power
The design would help to offset the costs associated with new generator as well as helping to lower costs of daily activities.
- Back-up generator on standby
This will help if main source becomes unusable for a period of time
- Educational uses for visiting residents
To have the ability to show them the alternative methods of power production
B. Constraints considerations
- Weather concerns that limit wind and solar power generation
Wind and solar are not constant which would limit their use and increase the use of backup power supply.

E. Testing Requirements
For this particular power system design, power simulation program such as
Modelica. This would enable the visualization of the design before it is
completed.
F. Safety and Security considerations
