Advanced Wayside Energy Storage Systems for Rail Transit. Transit IDEA Program.

摘要

This project explored the use of wayside energy storage systems (WESS) in rail transit systems. The analysis monetized economic and technical benefits for transit agencies but also considered other stakeholders. Navigant Consulting modeled the costs and benefits of various applications through hypothetical simulations as well as case studies using real data from our participating transit agencies: Greater Cleveland Regional Transit Authority (GCRTA) and Denver Regional Transportation District (RTD). Representatives from the two case study transit agencies participated on an expert panel to direct this research, along with the American Public Transportation Association, Sacramento Regional Transit District, and New York City Transit. The Analytica modeling platform was used to build a customized economic and technical WESS simulation model. The project approach consisted of 7 steps: 1) Objectives Identified objectives for transit agencies to utilize WESS. 2) Applications Identified the specific use for WESS to achieve the application. 3) Technologies Identified appropriate storage technologies to meet each application. 4) Benefits Identified and monetized benefits associated with each application. 5) Cost Estimated the capital and operating costs associated with each application. 6) Value Calculated the 15 year Net Present Value (NPV) to estimate the direct financial value of each application. 7) Combined Applications Optimized the NPV by combining applications.
