Cut Transmission Line Loss by More than 50%? EPRI Points the Way

The Electric Power Research Institute says a superconducting direct current (DC) cable could drop transmission line losses, one of the goblins in moving power from one place to another, by more than 50% — and that it could be available within 10 years using existing technology. Here's more on the report.

Yes, transmission line loss is a big deal. So are 20 years of underinvestment and the possibility that our power grid could choke on the growing amounts of wind and solar energy coming online. Transmission in the Smart Grid era will need a lot of help coping with these issues, and this cable technology could be one of the ways we do it.
