Infrastructure and Energy Alternatives

Infrastructure and Energy Alternatives

Infrastructure and Energy Alternatives (IEA) was an independent contractor until its acquisition by MasTec in early 2022. The firm now operates as a MasTec subsidiary, focusing on large-scale infrastructure construction. Its wealth origin is not publicly disclosed, as IEA is a corporate operating entity rather than a family office. IEA engineers and constructs projects across clean energy (solar, wind, battery storage), power generation (natural gas and alternative fuel plants), power delivery (transmission and distribution), and data centers. It also builds oil and natural gas pipelines, EV charging infrastructure, and civil infrastructure for water/wastewater and transportation. The firm has a strong US domestic focus, with offices across North America. It does not typically act as a financial investor; instead, it contracts for construction and engineering services. The firm is backed by MasTec's 80+ years of experience and 36,000 skilled professionals. It is certified as a Minority-Controlled Company by the National Minority Suppliers Development Council (NMSDC). No recent standalone operational event was publicly attributed to IEA separate from MasTec. IEA's structural differentiator is its role as a dedicated infrastructure construction arm within a larger publicly traded parent (MasTec). This structure provides access to significant resources, an owned fleet of specialized equipment, and the ability to handle complex, multi-billion-dollar projects across regulated and renewable energy sectors.
