Vestas will be offering UMPI cost estimates for several different options, including decommissioning the turbine and replacing it with another turbine, Rice said.
“If we were to decommission the turbine, we’d want to replace it with a renewable energy system that would provide similar energy and cost savings,” Rice said.
Those other renewable energy options could include solar panels, although officials with UMPI and the University of Maine System are in still “very early in the conversation” about their next steps, Rice said.
When the wind turbine at UMPI began operations in May 2009, exactly nine years ago, it was to produce 1,000,000 kilowatt hours per year and save $100,000 annually in electricity. In other words, over these nine years there should have been 9,000,000 kilowatt hours produced. But there have only been 4.7 million kilowatt hours produced as noted below. That means the wind turbine delivered at only 52% of expectations -- which were low to begin with. So if the power production delivered at only 52% of predictions, how did cost savings deliver at 100% of predictions?
Note that in identical manner, UMPI's "CO2 avoided" is unchanged from 2009 as well from - despite the fact that the turbine delivered at only 52% of going in prediction. In 2009 they predicted 572 tons of CO2 avoided and that's the number they continue to give out.
The University of Maine promised to share all information on the turbine. They have not delivered on this promise either.

"The 600 kilowatt turbine was installed in 2009 at a cost of $2 million. Since then, the turbine has generated 4.7 million kilowatt hours of electricity, the equivalent of powering 436 average American homes, according to the university. Officials estimate it saves UMPI approximately $100,000 annually in electricity costs."
From May 14, 2009
University officials anticipate the turbine will produce about 1 million kilowatt-hours of electricity a year and save the institution more than $100,000 annually in electricity charges. Once fully operational, the windmill is expected to save an estimated 572 tons of carbon dioxide from being released into the atmosphere each year.
