Nedonna Beach, Oregon Nedonna Beach is an unincorporated community in Tillamook County, in the U.S. state of Oregon. It serves as the U.S. terminus of the Trans-Pacific Express undersea cable and Southern Cross Cable. Nedonna Beach is west of U.S. Route 101 between Rockaway Beach and Nehalem Bay.
Trans Bay Cable The Trans Bay Cable is a high-voltage direct current underwater cable interconnection between San Francisco, California and Pittsburg, California. The 53 mi cable under San Francisco Bay and through the Carquinez Strait can transmit 400 megawatts of power at a DC voltage of ±200 kV, enough to provide 40% of San Francisco's peak power needs. Owned by SteelRiver Transmission Company, the line connects PG&E's Potrero Substation to its 230 kV transmission line in Pittsburg. The system was completed in November, 2010. The Trans Bay Cable project was the first HVDC system to use the "Modular Multi-Level Converter" (MMC) system.
