The Port of Los Angeles is the busiest port in the nation and is committed to becoming an environmental leader.  In 2001, with numerous environmental programs already in existence, Los Angeles has pushed the envelope by developing “Alternative Maritime Power.”

The "Alternative Maritime Power" or AMP is a program that focuses on reducing emissions from container vessels docked at the Los Angeles Port. Instead of running on diesel power while at port, AMP-equipped ships “plug in” to shore-side electrical power. By shutting down the ship’s diesel engines and switching to electricity, more than one ton of nitrogen oxides (Nox) and particulate matter (PM) are eliminated from the air for each day a container vessel is berthed.

The Port of Los Angeles is the first port in the world to use AMP technology for in-service container ships. On June 21, 2004, the Port of Los Angeles and China Shipping Container Line announced the grand opening of the West Basin Container Terminal at Berth 100, the first container terminal in the world to use Alternative Maritime Power.

The Alternative Maritime Power Program has helped reduce the dangerous pollutants that affect surrounding communities by powering massive container ships with on-shore electricity.  By eliminating the use of auxiliary diesel engines while container ships are docked, it has shown an average reduction of 95 per cent in Nox, Sox, and PM10 per vessel call.

The Alternative Maritime Power Program through offering unique implementation of technology and by providing cash incentives to steamship lines to install the AMP equipment has succeeded in improving air emissions in both the port and the surrounding area.

The AMP technology has been used for Naval vessels, Baltic ferries and cruise ships operating in Alaska for several years, but the Port of Los Angeles is the first to use this technology for in-service contained ships.
In April of 2006, the U.S. Environmental Protection Agency announced the recipients of its annual Clean Air Excellence Awards. This award recognizes and honors outstanding, innovative efforts that help to make the air cleaner. Two U.S. port facilities received this award, the Port of Seattle and the Port of Los Angeles. Both ports use the AMP technology.

One of the problems that ships have when they dock is that each port might have different frequencies and voltages.  A TEMCo Shore-Port-to-Ship Power Converter is an economical answer to this problem. These converters are used to convert frequency, voltage and phases.  The most common frequencies are 50Hz, 60Hz, or 400Hz. Common voltages are 208, 240, 400 and 460 volts.  TEMCo Shore-Port-to-Ship Power Converters also offer line isolation, harmonic cancellation and power factor correction.
