is expected to be completed in 2019. In Brazil, the Xingu-Estreito line over 2076 km (1290 miles) with 800 kV and 4 GW was completed in 2017, and the Xingu-Rio line over 2543 km (1580 miles) with 800 kV and 4 GW was completed in 2019, both to transmit the energy from Belo Monte Dam. As of 2020, no UHVDC line (≥ 800 kV) exists in Europe or North America.
