Between 2019 and 2025, demand for these critical units nearly tripled. Upgrading the electrical grid, expanding renewable energy, supporting new data centers, and reducing storm vulnerability all require this scarce equipment, alongside specialized materials that are difficult to manufacture. The Department of Energy has announced plans to strengthen the power grid and lower electricity costs, while offering funding
