In August 2015, the consortium named Ishikari Superconducting DC Power Transmission System (Chiyoda Chemical Engineering Plant, SEI, Chubu university, Sakura Internet) announced a successful transmission of 500m long HTS DC cable with a large current of 1.5kA (corresponding to about 300,000 households) and 100MVA in Ishikari city of Hokkaido, Japan. Furthermore, they started the DC current transmission from a solar power plant to a data center in Ishikari. There are no DC-AC conversions in the line and it is expected to be a highly efficient use of the power. A schematic of the system can be found below.
