I just wondered why they chose to transmit it as DC rather than traditional AC. Can't use transformers on that. But then again the farm would generate the power as DC and then have to be put through an inverter or motor/generator to get AC.
It's a toss-up, I guess.
Pretty big project. I would think they would want to use it themselves, but it may be the "end user" is just renting the land for "their" project.
