Trans Bay Cable will power San Francisco

SAN FRANCISCO, CALIFORNIA - A new electrical cable will soon be able to pump an entire power plantÂ’s worth of electricity into San Francisco.

The half-billion dollar Trans Bay Cable will connect San FranciscoÂ’s electrical grid with power plants and other power sources in Pittsburg.

The cable took six weeks to be laid from a ship that reached PG&EÂ’s switch yard at Potrero Hill, according to Trans Bay Cable LLC spokesman P.J. Johnston.

Power that could be carried by the cables after installation is complete could provide 40 percent of San FranciscoÂ’s power needs, Johnston said. Installation is expected to finish by March.

The project is being rolled out by a joint venture that includes Pittsburg, which operates the Pittsburg Power Co., and private companies and investors.

Approval of the project was instrumental in shutting down an aging PG&E power plant at Hunters View in 2006.

San Francisco officials have said they hope it will eventually help them shutter a 360-megawatt Potrero Hill power plant owned by Mirant Corp.

“The energy that the Trans Bay Cable will bring into San Francisco is integral to our efforts to close the Potrero Hill plant,” San Francisco Public Utilities Commission spokesman Tony Winnicker said.

Activists, city officials and PG&E, which competes with Mirant, have argued to state regulators that the Potrero Hill power plant could be shut down once the cable is operational.

But the California Independent System Operator has ruled that would leave San Francisco vulnerable during blackouts because there is no major source of generators in the city.

In a settlement agreement, City Attorney Dennis Herrera agreed to drop city lawsuits against Mirant in exchange for an agreement that it would shutter the plant and redevelop the site once the ISO rules that it is no longer needed to protect against blackouts.

China aims to reduce coal power production

BEIJING - China plans to slash coal-fired power capacity at its five biggest utilities by as much as a third in two years by merging their assets, according to a document seen by Reuters and four sources with knowledge of the matter.

The move to shed older and less-efficient capacity is being driven by pressure to cut heavy debt levels at the utilities. China, is, however, building more coal-fired power plants and approving dozens of new mines to bolster a slowing economy.

The five utilities, which are controlled by the central government, accounted for around 44% of China’s total coal-fired power capacity…
