Matthew:

How many HVDC lines are in operation in the continental United States? How much does it cost to build HVDC per mile?

The Wikipedia article that you pointed to offered a hint – a 40 km 8 GW line under the English Channel is estimated to have cost $2 billion (a billion UK pounds).

The article also mentions that HVDC is not appropriate for distributed sources that need a lot of taps into the line – it is best used when there is a very large power source that is a long way from a distant load center. That does not sound like it would work well for solar until such time as there are GW sized arrays. Today, the largest arrays in the world are at least one order of magnitude smaller than that.

Zippy-you may be an Electrical Engineer by trade – but unfortunately you’re not very up with latest Grid Supply technology. High Voltage DC power lines can cover large distances with minimal losses. 3% per 1000km. These are available from Swiss/Swedish industrial Giant ABB.

See http://en.wikipedia.org/wiki/HVDC

In other words, you can send Wind from Canada and the south of the USA into load centres with minimal loss.

You can send Solar from Arizona, California, Texas, Florida and Nevada all over continental United States.
