Ontario is partnering with Toronto Hydro to build a battery energy storage system for the Eglinton Crosstown light rail transit (LRT) line, which will increase the reliability of the line, lower operating costs and reduce emissions.
The power system, which is equivalent to a large battery, will be capable of providing backup and emergency power to the LRT line for up to four hours in the event of a wide-spread power outage, and replaces previous plans for a natural gas facility.
