Baker Village, 280 kW
This 280 kW array will soon be combined with a 20 kW system slated for installation near the Shirley Baker Commons. These two facilities are designed to produce all of the electricity Baker Village consumes in a typical year, which is approximately 375,000 kWh.
The electricity from these two arrays is used to power all electrical appliances as well as the geothermal heating and cooling system at Baker Village. When the panels produce more electricity than is being consumed the excess generation powers nearby homes in Decorah. Iowa’s net metering law allows Luther to receive a financial credit for surplus production. As a result, Luther draws on these credits when it uses electricity from the grid to power Baker Village on cloudy days, when the panels are snow-covered, and after the sun has set.Winneshiek Energy District to reduce leasing expenses. The Winneshiek Energy District will resell the SRECs to other persons and businesses in Decorah that want to reduce their carbon footprint.
In addition to SREC sales, Luther will pay its leasing expenses with funds that otherwise would have been used for electricity purchases as well as donations to the college earmarked for renewable energy. The intended purchase of the system will be financed via future avoided electricity purchases. Luther expects to pay less for the electricity from the array over the 25-year-rated life of the panels than it would to purchase electricity from the grid. As a result, the project helps to reduce Luther’s operating costs and greenhouse gas emissions over the long run.
