Idea 3 of 5 – MMA annual meeting – solar


Solar Energy Systems Town owned

It makes sense for the Town of Medfield to look at the installation and ownership photovoltaic arrays to generate electrical power.  The old landfill is an ideal candidate for such an array, which would be mounted on concrete ballasts that avoid damage to the membrane that caps the site.  I saw a presentation on a solar array in Easthampton on top of its capped landfill.

Easthampton installed its solar array by using both Borerego Solar (Borregosolar.com) and Tighe & Bond engineers.  Borrego will actually finance the installation in exchange for a 20 year contract, so the town does not have to put up any money if it opts to go that route.

Figure on using 5 acres per megawatt, or 6 acres per megawatt with the infrastructure included.  Cost tends to run about $4 m. per megawatt, and is more expensive on a landfill due the the higher cost of the ballasts over poles into the ground.

Parts are warranted for 25 years, and Borrego will include a 19th year bond to cover the cost of the decommissioning, if that is what the town wants.

The town can have access to the remote monitoring, and can even set up a kiosk at a school to tie it into the curriculum.

I spoke with Dartmouth’s town administrator, who shared with me that they own five solar arrays, and that it takes only two of them to generate all the electricity that the town uses.

There are other town owned sites that would be suitable, such as behind the Wheelock School.

  1. Pete, I have a lot of information – which I have given to Mike – regarding photovoltaic electric generation. You should speak with him in this regard or me when I return to Medfield.
    Best,

    Pete, I saw this article in the Globe about a solar array being installed in Scituate on top of their capped landfill. All energy produced will be used by the schools, town hall, etc. and is expected to save $250k per year. Seems like a great idea.
