  • CES One-Line Service reduces delivery time from up to nine months to just days, enabling faster project completion.
  • The service combines local branch support with strategically placed fulfillment centers across North America for quick assembly and delivery.

City Electric Supply (CES), Dallas, TX, officially launched its streamlined CES One-Line Service. First developed in 2019, the service has evolved into a nationwide offering that delivers panelboards and switchboards faster than ever through CES fulfillment centers in partnership with Siemens. The streamlined service allows contractors to go from diagram to finished product in days, a process that traditionally can take six weeks to nine months, while delivering a high-quality build every time.

"With CES One-Line Service, we’ve built a team and a process to deliver consistent, high-quality service for every customer," said Blair Feidler, VP of operations at CES, in the press release. "From a 400A panel to a 4,000A switchboard, our goal is the same: help branches and customers succeed by providing speed, accuracy, and reliability — everything they need to meet tight deadlines and take on challenging projects with confidence."

CES One-Line Service combines local branch support with six strategically placed fulfillment centers across North America, ensuring orders are assembled and delivered quickly. Trained by Siemens, CES teams follow a centralized, well-tested process that delivers more than 99% accuracy while allowing contractors to skip time-consuming takeoffs. All that’s needed are the one-line drawings.

“Our fulfillment centers are a key part of CES One-Line Service, empowering our branches to collaborate with customers in a whole new way,” said Rich Antonaros, director of CES Online North America, in the press release. “The speed of our process across the network lets branches focus on helping customers finish projects on time and secure the next big one.”
With $26 million in inventory ready for assembly, CES One-Line Service removes material delays from the equation. Contractors benefit from a streamlined process that delivers high-quality panelboards and switchboards wherever they’re needed, backed by Siemens expertise and CES’s commitment to customer success.

“City Electric Supply understands Siemens panelboard and switchboard technology from the ground up and delivers project solutions in record time. Their CES One-Line Service dramatically streamlines project management, offering rapid quotes and quick shipment to ensure projects stay on schedule and budget,” said Lesa Tate, national accounts manager at Siemens in the release.
