Siemens to Provide Technology for National Grid Substation Project

National Grid, a multinational electricity and gas utility, has chosen Siemens to provide its 63 kA arc-resistant switchgear technology for the utility’s new electric substation in downtown Providence, Rhode Island. The new location, replacing the National Grid’s existing South Street Station, will provide reliable, efficient power to the utility’s customers including the City of Providence and much of downtown Providence. Siemens’ 63 kA type GM-SG-AR switchgear is designed to improve power reliability and includes arc-resistant features that increase safety conditions for workers and operators. The technology’s design will also allow National Grid and contractor TRC Companies, Inc. to reduce the project’s physical footprint, resulting in significant project cost savings.

Siemens recently extended the rating of its GM-SG-AR arc-resistant switchgear to 63 kA, which broadens its applications into the oil and gas, chemical, and power generation spaces that require the highest level of arc-resistant, fault-current interrupting.

“As power systems become increasingly complex, utilities and power operators rely on advanced technologies like our 63 kA type GM-SG-AR switchgear to operate the power grid more, efficiently, safely, and reliably than ever,” said Brian Dula, vice president of Siemens Medium Voltage and Systems. “We’re proud that our work with National Grid and TRC on this project is bringing the next generation of power technologies into the substation in an innovative and cost-effective way.”
