| Wind Power at Gusta= vus |
| The feasibility of = wind power on campus has been discussed since the early 1990s. | |
| A student initiated= feasibility study was begun in May 2001, driven by improvements in wind turbine technology. | |
| The wind climate on= campus has been monitored continuously since May, 2001 using several weather station= s. | |
| From October 2003 u= ntil October 2005, a 50 m monitoring tower from the Minnesota Department Commerce was = also used. | |
| Wind data have been= combined with power curves for turbines and topographic data to determine potential energy production for several turbine sites. | |
| Energy production h= as been compared to consumption for several years in Ό hour increments and results built into financial models. |
Combining Wind Spee= ds and Power Curves to Predict Production
| In 2005 we hired an= attorney and a consultant to help us sort out some of the issues. | |
| In May 2006, we exp= lored the possibility of selling electricity from one or two turbines to SMMPA by responding to their CBED based request for proposals. We were turned down. | |
| We have since devel= oped an agreement with the City of St. Peter allowing us to consume as much turbi= ne produced electricity as possible without penalty. | |
| We have also come t= o an agreement (in principle) with SMMPA to purchase any excess electricity fo= r a reasonable rate (3.2 cents/kWh). |
| Although we have be= en in discussion with Clipper Wind for almost two years, they now report approximately two year wait in the queue for turbines. Other manufacturers are reporting sim= ilar timelines. | |
| The permitting proc= ess has been explored but cannot be initiated until a turbine supplier is identified a= nd a site (or sites) are chosen. | |
| We plan to apply fo= r federal Renewable Energy Production Incentive (REPI) payments which are currently= 1.9 cents per kwh (fully funded) for electricity that is sold. |
Benefits of wind po= wer at Gustavus
| Economic--keep ener= gy dollars local | |
| Reduced air polluti= on | |
| Reduced impact from= coal mining and transport | |
| Financial save mo= ney for the College |
| Annual electric pro= duction from one Clipper C93 (2.5 MW) turbines is estimated to be between 6.5 and 7.5 million kWh. | |
| Gustavus currently = uses around 16 million kWh. | |
| We estimate that we= could save about $380,000 by not buying about 7.5 million kWh of electricity. Our excess would be only about 440,00= 0 kWh returning $14,000 in revenue. We should also be able to receive REPI fund= for the excess amounting to between $5,000 to $8,300 (60% to 100% level). | |
| While we do not hav= e a firm quote or contract for pricing on turbines we have been told that the total cost will be very close to $3 million per turbine. | |
| With two C93 turbin= es, we estimate that we could reduce what we purchase by about 10.5 million kWh = to around 5.5 million kWh and save approximately $534,000. The excess electricity from two turbi= nes can be sold to SMMPA for about $135,000. REPI funds would range from about $48,000 and $80,000. | |
| A single turbine wo= uld require about 10 years to pay off and return more than $5 million over 20 years.<= /font> | |
| Two turbines would = require about 9 years to pay off and return just under $9 million over 20 years.<= /font> | |

Educational Value of Having Turbines On Campus
| Contribute to the i= dentity and culture of Gustavus | |
| Symbols embodying o= ne of our core values, our commitment to protecting Creation and fostering a healthy environment | |
| We would like every= student or person that sets foot on campus to feel and see our commitment to Creation and that will only happen if the turbines are located on campus. | |
| Prospective student= s, their families, and other groups that come to tour the turbines will also make = the direct connection between Gustavus and the turbines. | |
| Practically, it wou= ld be much easier (and environmentally symbolic) to walk students and groups out to = the turbines rather than drive. | |
