The Los Angeles County Metropolitan Transportation Authority has signed a $3.6 million contract with Vycon, a clean energy storage system manufacturer, to put up a Wayside Energy Storage Substation that will harvest power from speeding subway trains.
To be installed at the Red Line Westlake/MacArthur Park Station, the W.E.S.S. will use Vycon’s Regen flywheel energy recovery system.
This will reuse part of the energy to be collected by absorbing and storing in kinetic energy regenerated by braking trains and returning this stored energy to trains in acceleration in a “clean and instantaneous form,” the company describes.
“This recycling of energy will save electricity otherwise wasted in the form of heat,” the company added.
The W.E.S.S. is a project backed by the Federal Transit Administration under the Transit Investments for Greenhouse Gas and Energy Reduction, with funds made available through the American Recovery and Reinvestment Act of 2009.
The new W.E.S.S. can potentially replace chemical battery-based Traction Power Substations, by providing voltage levels support, lower cost for peak power demands, and reduced energy consumption, said Vycon.
It can also help in eliminating the tendencies for train slowdowns and stop or starts by correcting low voltage occurrences; increasing the system’s reliability by means of greater power capacity; and removing redundancy in power source for adjacent substation blackout or emergencies.
“Metro is committed to an extensive energy savings and sustainability program,” said L.A. Metro’s project manager Frank Castro.
Mr. Castro said they have installed 2 megawatts of photovoltaic equipment in the last five years, and the new Wayside Energy Storage Substation project with Vycon will add another 2 MW of green energy output to the railway system. – EcoSeed Staff
