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.
