A 53-mile submarine power cable between Pittsburg and San Francisco could be switched on within a month.
The Trans Bay Cable will transmit up to 400 megawatts of power across the Bay from power plants and other sources of electricity.
The cable was scheduled to become operational in March.
However, the $505 million project is moving ahead of schedule, according to PJ Johnston, a spokesman for the joint venture that’s financing and installing the cable.
“Testing has been going well,” Johnston said Wednesday. “We’re more than a month ahead of schedule.”
The planned date to switch on the cable is now Feb. 1, according to Johnston.
If the 10-inch cable’s full capacity is used by power traders, it could provide as much as 40 percent of San Franciscans’ peak power needs.
The Potrero Power Plant’s main generator and smokestack generate roughly 360 megawatts of power.
