- Boise, Idaho — SEL will expand to accommodate its growing team with a $25 million investment, including the purchase and remodel of a 170,000-square-foot building. This expansion, expected to be completed in 2026, will support continued innovation and growth in the region.
- Charlotte, North Carolina — SEL will build a 50,000-square-foot office building adjacent to its current facility at 901 Center Park Drive. The $15 million expansion will support the growth of its panels and enclosures manufacturing operations and is scheduled for completion in 2027.
