No, I don't believe there are large hidden costs, and I don't believe that even the discussion on DC and converter stations are actually hidden costs. I believe they are quite obvious when you price out and get capital cost estimates. The basic design principles will set forth a technology and the technology will drive a cost, and I think that's pretty well understood in the industry. I don't think that element of costing would be a surprise to the study.
