Trans Bay Cable
The Trans Bay Cable is a high-voltage direct current (HVDC) underwater transmission cable interconnection between San Francisco, California and Pittsburg, California. The 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. The line connects PG&E's Potrero Substation (formerly the switchyard for Potrero Generating Station) 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. History 1998 San Francisco power outage Until recently, San Francisco had two power plants within city limits to support local demand: Hunters Point Power Plant (shut down in 2006) and Potrero Generating Station (shut down in 2011); the remaining electric load for the city is supplied through the grid.

Peaking Power Plant
Peaking power plants, also known as peaker plants, and occasionally just "peakers", are power plants that generally run only when there is a high demand, known as peak demand, for electricity. Because they supply power only occasionally, the power supplied commands a much higher price per kilowatt hour than base load power. Peak load power plants are dispatched in combination with base load power plants, which supply a dependable and consistent amount of electricity, to meet the minimum demand. Although historically peaking power plants were frequently used in conjunction with coal baseload plants, peaking plants are now used less commonly. Combined cycle gas turbine plants have two or more cycles, the first of which is very similar to a peaking plant, with the second running on the waste heat of the first. That type of plant is often capable of rapidly starting up, albeit at reduced efficiency, and then over some hours transitioning to a more efficient baseload generation mode. C ...

California Independent System Operator
The California Independent System Operator (CAISO) is a non-profit Independent System Operator (ISO) serving California. It oversees the operation of California's bulk electric power system, transmission lines, and electricity market generated and transmitted by its member utilities. The CAISO is one of the largest ISOs in the world, delivering 300 million megawatt-hours of electricity each year and managing about 80% of California's electric flow. History The California Legislature created the CAISO in 1998 as part of the state restructuring of electricity markets. The legislature was responding to Federal Energy Regulatory Commission (FERC) recommendations following the passage of the federal Energy Policy Act of 1992, which removed barriers to competition in the wholesale generation of electricity business. FERC regulates CAISO because interstate transmission lines fall under the jurisdiction of federal commerce laws. Management CAISO's leadership consists of executive ...

California Public Utilities Commission
The California Public Utilities Commission (CPUC or PUC) is a regulatory agency that regulates privately owned public utilities in the state of California, including electric power, telecommunications, natural gas and water companies.

History On April 1, 1878, the California Office of the Commissioner of Transportation was created. During the 19th century, public concerns over the unbridled power of the Southern Pacific Railroad grew to the point that a three-member Railroad Commission was established, primarily to approve transportation prices. However, the Southern Pacific quickly dominated this commission to its advantage, and public outrage re-ignited. As experience with public regula ...

Power Outage
A power outage (also called a powercut, a power out, a power failure, a power blackout, a power loss, or a blackout) is the loss of the electrical power network supply to an end user. There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. Power failures are particularly critical at sites where the environment and public safety are at risk. Institutions such as hospitals, sewage treatment plants, and mines will usually have backup power sources such as standby generators, which will automatically start up when electrical power is lost. Other critical systems, such as telecommunication, are also required to have emergency power. The battery room of a telephone exchange usually has arrays of lead–acid batteries for backup and also a socket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
