— FACT SHEET - SYSTEM INTEGRATION AGP Polska, Reliable power supply to support Metro

Innovative traction power supply solution incorporating the world’s largest wayside energy storage system, which captures braking energy from decelerating metro cars and feeds it back to accelerating trains.

— In 2015, the 6.1 kilometers central section of the Customer benefits 01 New Metro Line 2 in Warsaw, Poland second metro line, called M2, was commissioned • Enhanced energy efficiency of metro line through eight meters under the river and serves over reuse of braking energy 140,000 passengers a day on working days. It is • Continuous operation, high performance and pro- powered by seven underground substations sup- ductivity supported by reliable and high-quality plied by ABB that are working dependably. power supply • Improved ecological footprint and reduced ABB’s solution operating costs of new east-west connection • Turnkey supply of five combined traction and • Scalable systems using state-of-the-art and auxiliary substations rated at 15 kV / 825 V DC / proven technologies enabling future extensions 400 V AC and two auxiliary substations rated at • Optimal solutions based on long experience and 15 kV / 400 V AC in-depth knowledge of the demands of the grid as • A 40 MJ (megajoule) wayside energy storage sys- well as storage technologies tem (ESS) based on Envistore® super-capacitors to • Proficient turnkey implementation by experienced recuperate and reuse braking energy from metro system integrator cars. The ENVILINE™ DC wayside ESS is the largest of its kind in the world. • Turnkey project including system studies and specifications • Supply of complete range of substation equip- ment including AC and DC switchgear, transform- ers, rectifiers, substation automation, control and protection systems as well as supervisory control and data acquisition (SCADA) system abb.com/substations Baden,5400 Bruggerstrasse 72 Power Grids - Integration Grid Ltd.
