Con Ed strengthens emergency response with Siemens mobile substations
Con Edison has purchased six mobile substations from Siemens to be used for rapid emergency response in the case of storms, for example.
The rapid deployment mobile substations will help Con Edison increase resilience by reducing the impact of power outages during extreme weather, unexpected events, or even during routine maintenance to minimize downtime.
The New York utility company ordered six custom-made mobile substations, each containing a seven-circuit breaker lineup of Siemens 8DA10 gas-insulated medium voltage switchgear, providing power up to 93.3 megavolt ampere (MVA) in selectable voltage levels.
They come with a special slide-out and slide-up functionality which allows a very compact design of the substation so that it can be easily transported to any location within the utility’s network without any transportation permits.
“Part of resiliency strategy – in addition to preventing power outages – is to restore service to customers as quickly as possible during a major storm or other emergency,” said Robert Brantley, Chief Engineer of Equipment & Field Engineering at Con Edison. “These mobile substations we developed with Siemens are groundbreaking technology that will help us serve our customers better during extreme events.”
“Traditionally when a utility’s substation equipment is impacted by extreme weather, or even needs to be taken out of commission for routine maintenance, outages can occur,” said Brian Dula, head of Siemens Medium Voltage & Systems business Unit in US. “Our goal in designing these mobile substations is to give utilities like Con Edison the flexibility to bring the technology right to where it’s needed and the ability to quickly energize so as to minimize the duration of an outage.”
