Utility Grid Modernization

SEL provides grid modernization solutions that improve reliability, resiliency, and readiness for future demand—at any scale.

The electric power grid is an engineering marvel—the largest, most complex machine ever built—but aging systems designed to meet 20th century needs are straining under 21st century demands. The shift toward renewable energy and the accelerating electrification of transportation and economic activity demand upgrades to the grid and the systems that protect and control it.

The SEL Approach

SEL offers a simpler, leaner approach to modernization programs, with a single PO for the entire process—from design and permitting through building, installation, and commissioning. This simplifies project management, budgeting, and timelines, ensuring on-time delivery.

You have access to SEL engineering experts throughout the entire process, from design through commissioning—and even after the modernization projects are complete. Our global corps of application engineers provide technical support for the entire lifetime of every SEL-manufactured device, at no additional cost.

It all adds up not only to smoother program implementation, but also to lower O&M costs for the entire life of the modernized system.

When you partner with SEL on a modernization program, you have access to our engineering experts before, during, and after all the projects are done.

SEL Engineering Services can assist with everything from protection studies and system modeling to design, procurement, installation, and commissioning.

We use advanced modeling and simulation, informed by decades of power engineering experience, to analyze system requirements, validate full system designs, and optimize the performance of the grid through the devices that protect and control it.

After your modernized systems are commissioned, whenever technical questions arise and devices need service, we’ll be ready to help. We support every device we manufacture and every system we design for the entirety of its lifecycle.

SEL customer service reps and application engineers are stationed in regional offices across North America and around the world, so you can always count on reaching a friendly, knowledgeable human who can connect you with the resources you need.

Partnership and Support

We believe you should never have to worry about whether your protection and control systems will be working when you need them most. That’s why you always have access to SEL engineers—and every device we manufacture comes with a ten-year warranty and free technical support.

After your modernized systems are commissioned, our application engineers provide technical support for SEL products at no cost.

As long as your SEL products remain in service, you have free access to direct technical support from SEL engineers—not just a handful of customer-facing product engineers, but a large corps of application engineers who are intimately familiar with the way our devices are deployed and the systems they support in the field.

Customer support staff and application engineers are stationed in regional offices across North America and around the world.

No matter how often you need to call or how long your SEL products have been in service, our customer service and technical support professionals are ready to help.
