This weekend, our family did something that we should’ve done a long time ago: we explored the Portland Trails system. My son has been working on a section of it as part of a class project. He wanted to show us the portion his class had been working on, so we packed some water bottles and headed out.
I was pleasantly surprised by how much undeveloped land there still is in the city. In our neighborhood, the trails are mini-nature walks that connect different neighborhoods together, particular around the Lyseth and Moore schools. Eventually our son led us to a section of the trails near his class project that he kept referring to as “the landfill.”
The Landfill
Of course, I didn’t think he literally meant a landfill, as in a “town dump,” but I was wrong. It was, in fact, a capped former landfill tucked away behind Dragon Cement near the Portland/Falmouth line. Apparently it now serves as a Dog Park that is managed by the city. I grew up in Maine, but I’m pretty new to Portland, so I had no idea the former landfill/dog park was there.
There were several signs cautioning against allowing pets to drink from the water (duh!). The grassy hill goes up 70ft to the summit. That doesn’t sound impressive, but it sure looks it, especially after trekking a few miles through the woods with your kids. On the top of the hill, there were some people setting off model rockets. We didn’t dare venture all the way to the top; we didn’t want anyone to catch a plastic cone glued to an M80 in the eye.
It was pretty nice there. You might not guess that it was once a landfill if it weren’t for the orange water oozing out from the base of it.
It was pretty windy that day, which got me to thinking…
Wouldn’t it be Cool?
I’m a sucker for a good story. What better symbol is there for rampant consumerism than a giant pile of rotting American trash? When it comes to being caretakers of the earth, a landfill is a black eye on the face of humanity. What if we could take this place where we once piled our garbage, and turn it into a small wind farm?
Reading up on wind power at Wikipedia and on WikiAnswers (admittedly not the most scientific sources), wind turbines typically run at 10% – 40% of their “capacity factor” based on how much wind there is. So a 1MW wind turbine (large, but not unheard of) at 10% capacity (picking a number at the low end) produces 875 MW over the course of a year. An average household uses roughly 10MW/year, so that’s about 90 houses worth of power.

Obviously, more wind turbines means more power and more homes running on green, renewable energy. There are about 4,210 households in North Deering, so it’d take a whopping 46 turbines to light up the whole neighborhood (not likely!).
Note: I am no power engineer… this is very back-of-the-envelope math by a highly unqualified blogger. Take this with a huge grain of salt.
A Few More Benefits
As I was walking around the old landfill, I noticed that there are already some pretty beefy power lines running adjacent to the site. Wouldn’t it be great if you could just “tie into” the existing lines and get the turbines onto the grid?
I envision a scenario where the City of Portland leases the land that it owns atop the landfill to a green energy company, perhaps with offsetting short-term tax incentives to the prospective lessor, to mitigate taxpayer risk.
The Downsides
I’m sure there are lots of people who would hate to see the dog park mutilated this way. And dog owners have already been pushed out of park after park in Portland – if this little project pushed them out again, there’d be a lot of howling, angry dog owners in this town.
Although the neighborhoods are a pretty good distance away from the site, I’m sure there are people who are close enough (Charlotte Drive, Apple Ledge Drive, and Ledgewood Drive to name a few) that would hear the wind turbines and object to the sound. They would also rightly have valid concerns about their property values.
I have no idea if the idea makes business sense. I know nothing about erecting, operating, and maintaining a wind turbine. I don’t know what’s involved when it comes to selling electricity to a power utility. This might be a financial loser from the get-go, and if it is, then it should be nothing more than an novel idea. Portland needn’t waste time and money on another Kittery debacle.
But it seems like such a neat idea – what do you think?
