According to the article during testing in July, the cable is under refrigeration. The article stated that it was the longest superconducting cable so far that is operational in an urban core.

South Korea did it first in 2019 but with a 1km cable instead of a 1.2km cable.

If need low temperature wouldn't the refrigerator system use up energy and negate the benefits?

My thoughts too. Not enough info in the article on how they achieve high-temperature superconducting (although it is called HIGH temperature superconducting, it seill needs refrigeration, just not to as low as 4K degree).
