Assessing and Measuring Benefits of Wayside Energy Storage Substations for the LACMTA Metro Gold Line

County Metropolitan Transportation Authority (LACMTA), Turner Engineering Corporation (Tenco), and VYCON, with the support of the City of Los Angeles Mayor’s office are performing a feasibility study for a project to demonstrate a wayside energy storage substation (WESS) on the LACMTA Pasadena Metro Gold Line (Gold Line). The project goal is to quantify and demonstrate the benefits of using a WESS in place of a conventional traction power substation as an economically viable “green” solution to power expanding traffic on an existing urban light rail line. The first phase evaluated proposed WESS sites at Avenue 61 and Lake Avenue on the Gold Line, where operating conditions indicate there is a need for additional power. The feasibility study showed that WESS can reduce power bills by reducing energy consumption and peak power demand charges. This will help LACMTA reduce operating costs and help its utility suppliers reduce power demand during critical peak periods. WESS can provide line voltage support for maximum current draw conditions, to prevent undervoltage conditions. Finally, WESS can be a useful component which can significantly lower the overall capital cost of a light rail traction power system, for new construction or for line renewals.
