Four years ago the College of the Atlantic in Bar Harbor was given the 125 acre Peggy Rockefeller Farms.
About six weeks ago the school received more than one half a million dollars for the development of a sustainable food program at the farms.
Now another 200 thousand dollar grant is headed to MDI to fund the Renewable Energy Demonstration Projects at the farms.
The grant comes from the Arthur Vining Davis Foundations and will be used to monitor how the farm gets and creates power.
It will also create a lab for education and outreach, with a goal of using zero fossil fuels on the farm.
