Renewable energy infrastructure represents the fastest-growing application segment in North America's electric insulator market, driven by unprecedented capacity additions and the critical need for grid connection infrastructure. • North America's renewable energy capacity reached 571,519 MW in 2024, with the United States alone contributing 427,886 MW, representing a substantial increase from previous years. This massive capacity requires extensive transmission and distribution infrastructure for grid integration. • The region grew by 45.9 GW (8.7%) in renewable capacity in 2024, driven primarily by expanded solar and offshore wind installations. The U.S. added 38.3 GW of solar capacity in 2024, a 54.0% increase from 2023. Each new renewable project requires transmission connection, substation integration, and collector systems all demanding substantial insulator installations. • Developers and power plant owners are working on plans to add 62.8 GW of new utility-scale electric-generating capacity in 2024. This unprecedented pipeline of renewable projects creates sustained demand for insulators across all voltage classes and product types. • Solar and wind projects are often located in remote areas with abundant renewable resources, requiring long transmission lines to connect to population centers. These new transmission lines require suspension, tension, and post insulators for reliable power delivery. • The U.S. hollow-core insulator market is supported by large-scale infrastructure upgrades and resilient grid construction projects, with wind and solar integration into long-distance transmission networks increasing high-voltage insulator demand. • Renewable projects require substation infrastructure for voltage transformation and grid interconnection.
