ZGlobal performed a comprehensive economic and reliability analysis in support of the $500 million transmission project which was successful in justifying project benefits to the San Francisco ratepayers. ZGlobal’s testimony was filed with the Federal Energy Regulatory Commission (“FERC”) which led to the approval of the project. The Trans Bay Cable is a high-voltage direct current (HVDC) underwater cable interconnection between San Francisco, California, and Pittsburg, California. The 53-mile cable under San Francisco Bay and through the Carquinez Strait can transmit 400 MW of power at a DC voltage of ±200 kV, enough to provide 40% of San Francisco’s peak power. The system was completed in November 2010.’ZGlobal performed a comprehensive economic and reliability analysis in support of the $500 million transmission project which was successful in justifying project benefits to the San Francisco ratepayers.
