The Pacific DC Intertie carries power from the Pacific Northwest into Los Angeles and is equipped with elaborate grounding systems: in Oregon, over 1000 electrodes are buried in a ring with a circumference of 2 miles (3.2 kilometers), and in California, huge electrodes are submerged in the Pacific Ocean a few miles offshore.
