Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Yes, but you also have to factor in the incremental capital cost of the transmission network required, and the costs of transmission loss.  Anyone know a simple formula for calculating transmission loss as a function of transmission distance for a given voltage? At one point does it become uneconomic to transmit solar energy over long distances?  Does it make sense to transmit solar energy not just South/North for increased yields, but also East West for increased daylight window?

As a quick estimate, HVDC is a capital investment of roughly $1.5 million/km (above ground, land based). The losses are supposed to be about 3% per 1000 km.

Thanks. Losses much less than I would have guessed.  Almost immaterial in the context of the efficiencies a larger grid can facilitate.
