Wind Energy in Higher Education
Case Study: Carleton College Northfield, Minnesota
CARLETON COLLEGE has a 350-foot tall mascot that is setting a new trend among universities by providing both revenue for the school and clean energy for the community. In September 2004, Carleton College dedicated the first college or university owned commercial-scale wind turbine in the nation to complement the college’s environmental statement, which aims to “be a model of environmental stewardship by incorporating ideals of sustainability into the operations of the college and the daily life of individuals.”
The 1.65 megawatt (MW) turbine is located about a mile and a half east of Carleton’s Northfield, Minnesota campus and has become “a popular destination for runners and bikers,” according to Carleton student Dave Holman. “Students love it, the community loves it, and alumni double love it…because it makes sound economic, PR, and ecological sense.”
A bit of friendly rivalry is common among schools, and other nearby universities are getting in on the action as well. Already, the University of Minnesota at Morris has installed a 1.65 MW wind turbine, and St. Olaf College in Northfield, MN is anticipating commissioning a 1.65 MW turbine in July 2006. Holman encourages the rivalry “because when we compete to do good things for society, everybody wins…and tell Olaf that Carleton’s currently winning,” he jokes.
Carleton College is a “local pioneer,” according to Bruce Anderson of RENew Northfield, demonstrating the economic and performance viability of wind development in the community. As the Project Manager f Facilities Planning and Management, Rob Lmppa says that this has been a “great learning experience.” And he is not alone. Already, Lamppa has given 50-60 tours of the turbine to school groups, individuals, and other bus loads of interested groups.
Integrating Wind in the Classroom
Many school wind projects are partially motivated by the educational opportunities in math, science, business, policy, and environmental studies, which are preparing their students with skills in a fast-growing industry. At Carleton, a variety of departments have been involved in various stages of the turbine project, such as, blade design, wind mapping for site assessment, and data conversion. For example, each month, the Carleton College Physics Department posts the wind production data in their building to keep tabs on the turbine electrical generation and revenue stream, over $384,000 to date.
Laying the Groundwork for University Wind Energy
Carleton’s installation of a 1.65 Vestas turbine was the culmination of approximately two years of planning and project development as well as an integral part of larger plans for greater Carleton campus sustainability and active renewable energy planning in the Northfield community.
During the summer of 2002, local citizens group RENew Northfield helped to convene a Northfield community wind energy task force that included the City of Northfield, the Northfield School District, Carleton College, and St. Olaf College. The task force identified a windy site on a farm about 1.5 miles east of Carleton’s campus. The college’s Board of Trustees officially approved the project in February 2004 and the project proceeded on schedule, commissioning and dedicating its turbine in September 2004.
Now that the local community has lived with the turbine for nearly a year and a half, Anderson says that there is generally “broad and strong support for the Carleton wind turbine.” A number of people have called his office at RENew Northfield just to say that they are thankful that the Carleton turbine is in their community. Anderson adds, “many view this project as a symbol of progress and pride in the community.”
Wind Economics and Policy
Electricity from the wind turbine is being sold to Xcel Energy for local use in the Northfield area. Xcel is paying 3.3 cents per kWh through a fixed 20 year contract, under the terms of Xcel’s standard small wind tariff (available for wind projects under 2 MW in Minnesota).
In addition to selling electricity to Xcel, Carleton is receiving 1.5 cents per kWh generated from the State of Minnesota via the Minnesota Renewable Energy Payment Incentive (MN REPI) program. The $1.8 million project at Carleton also was aided by a $150,000 “Community Wind Rebate” from the state of Minnesota. The rest of the capital expenditure was provided from Carleton directly.
The college expects to recoup its investment with interest within 10 to 12 years. After two semesters of independent study on the economics of the turbine, Holman suggests that “Carleton should invest in a wind farm as part of its endowment because it is an incredibly good investment. Wind for Carleton has the risk level of a bond, but returns like a stock with 8-12% per year. In addition to a yearly revenue stream of about $250,000, the PR value of the turbine has been immeasurable.”
By generating wind power, the college offsets about 40% of its electricity use, significantly reducing harmful emissions of carbon dioxide, carbon monoxide, sulfur dioxide, and mercury. Over the life of the turbine, the college will avoid producing 1.5 million tons of carbon dioxide, which is important to students at Carleton who view the turbine as “a very strong piece of their school’s identity,” according to one student.
Paving the Way - St. Olaf and Others Follow Suit
Carleton might find itself to be a trendsetter if other colleges and universities in the Midwest continue to follow through on their own plans to install wind turbines. St. Olaf College, the University of Minnesota at Morris, as well as some k-12 schools are catching on to the benefits of installing a wind turbine. St. Olaf College, located just across town in Northfield, received a $1.5 million grant from Xcel Energy’s Renewable Development fund to install a turbine of their own to match Carleton’s machine. Commissioning is scheduled for July 2006. St. Olaf intends to use the energy directly for its campus rather than sell it to the grid, and expects to supply approximately 30% of the campus electricity demand with wind each year.
St. Olaf also has plans to incorporate the turbine into curriculum with “a really cool set of courses called Campus Ecology I and II in our environmental studies program,” according to Pete Sandberg, Assistant Vice President for Facilities at St. Olaf. The turbine will also likely be integrated into an interim course looking at sustainable and renewable materials, in addition to, energy. “I think the educational uses will multiply pretty quickly beyond anything we can imagine right now,” says Sandberg.
When asked if the college is pleased with the turbine experience thus far, Sandberg echoed the comments of many who have worked in wind project development: “It has been very challenging!”
The community around St. Olaf has been generally supportive of the project. According to Pete Sandberg, Assistant Vice president for Facilities at St. Olaf, “we've had only positive feed back – no opposition, in fact, at the public hearing for the county conditional use permit, a Northfield realtor spoke, and said he believed that the value of properties with a view of the other turbine in Northfield were enhanced!”
Why is a wind turbine such a good fit for schools and universities? “We generated most of our electricity for most of our history,” says Sandberg about the college as its own utility. “We see it as just another way we contribute to keeping the place going as efficiently as possible.”
In the first quarter of 2006, St. Olaf College signed a turbine purchase contract with Vestas, and has installed the footings, transformer, and wiring in the new electrical equipment control room. Construction is scheduled for completion in July 2006. All of the work to date has been paid from college capital funds allocated to the project, which includes the first installment payment of $400,000 to Vestas.
To the northwest, the University of Minnesota at Morris broke ground for its own Vestas 1.65 MW turbine in November 2004, and began producing electricity for the campus in March 2005. Installed at the University’s West Central Research and Outreach Center, the turbine is the first commercial-scale wind energy project at a public university. The turbine supplies the campus with 5.6 million kWh per year, which is more than half of its electricity needs. Many colleges and universities around the U.S. that don’t have wind resources enough for their energy needs are purchasing green power to support renewables on campus. View a list of universities purchasing green power on the Green Power Network.
As has been demonstrated by multiple successful k-12 school projects in Minnesota and Iowa, wind turbines can be a great fit for educational institutions because they provide a clean energy, a new source of revenue and educational opportunities for students. Also schools sometimes have the option of using a wind turbine to directly offset their energy use, which can be a significant economic advantage.
As more and more schools across the nation “go green” in a variety of ways, the Midwest is leading the way for wind.
