Question 17 12 pts Tri-State Generation is a electric power cooperative serving rural electric associations in Colorado and adjacent states. It is currently the subject of a bill passed by the Colorado State Legislature and signed into law by Governor Hickenlooper in 2013 whereby Tri-State isto generate 25% of its future electric power requirements from renewable resources. Tri-State opposed this bill due to the estimated $4 billion in costs which will be imposed on its customers for the conversion from fossil fuel to renewable sourced generation. As an exercise in estimating the scale of the renewable resources which will be required, solve the following problem Assume that instead of a 25% renewable requirement, Tri State is ordered to shut down all of its coal-fired generation and replace it with wind power. The question is (A.) how many wind turbines would be required to comply with such an order, and (B) how much land area would have to occupied to accommodate this number of turbines. The information to answer these two questions is as follows: Existing Coal-Fired power plants operated by Tri-State: Total Tri-State Capacity Share Name Location (MW) (MW) Craig Colorado 1311 655 Nucl Colorado 100 100 Total Tri-State Capacity Share Name Location (MW) (MW) Craig Colorado 1311 655 Nucia Colorado 100 100 Escalante New Mexico 245 245 Laramie River Wyoming 1710 410 San Juan New Mexico 1800 40 418 418 Springerville Arizona "This is the official nameplate" capacity of each plant, le the maximum design output which the unit is capable of. **Megawatts Assume that on average the Tri-State plants operate at an 80% capacity factor, ie, the level of output they run at over a year considering maintenance, demand level outages, etc. Then assume the wind turbines have a design power output (again "nameplate") of 3.0 MW each and that they will operate at 25% capacity due to suitable wind speeds and maintenance requirements. Lastly, each wind turbine requires 80 acres of land for wind clearances, wildlife protection, and other location considerations.
