17th and Columbia??? I know that intersection and I know there is no substation there. I can also tell you that is on the flat part of North Portland...

Its a substation ATS

The building across the street to the north is Native American Rehabilitation Association of the Northwest, INC.

The substation has been there at least twenty years.

The US economy is expected to expand at a rate averaging 2% per annum for the foreseeable future. Moreover, it is anticipated that industrialization and urbanization of the developing world will occur at a faster pace, resulting in the prospect in 2050 of a planet with several billion more inhabitants aspiring to the standard of living now typical of the developed world. Substantial increases in energy production and consumption will invariably follow to fulfill and sustain these developments and expectations. The challenge will be to supply these energy requirements in North American and worldwide in the most efficient and environmentally benign manner with minimal emissions and effluents of any kind.

Hmmm... Interesting. That looks like a large substation with at least 4 underground cable connections. The high security seems a bit strange (usually just chain link fence's on stuff like this... Well in the UK at least) as does the description of 30+ dump trucks leaving site 24x7 for 6 months. If there are any large recently built or expanded industrial area's nearby It could just have been a planned upgrade to cope with additional load. I notice (using Google street-view) that there is at least one building overlooking this site, do you know anyone working/living in there that might have seen the build process?

It is possible that it's related to this Continental Supergrid
