## Federal Funding to Mitigate Critical Transformer Shortages

Targeting lead-time bottlenecks and severe weather vulnerability, the funding package co-finances procurement and installation of mobile emergency spare autotransformers and ballistic shielding at key 230 kV, 345 kV, and 500 kV transmission substations.

Participating utilities must implement smart digital monitoring packages—including continuous fiber-optic winding thermometry and multi-gas DGA sensors—to extend the operating lifespan of aging bulk power transformers.

## Unlocking Transmission Capacity with Advanced Conductors and DLR

Over $800 million of the funding is earmarked for installing real-time Dynamic Line Rating (DLR) sensor arrays and reconductoring constrained transmission lines with advanced composite-core conductors.

The initiatives aim to unlock an estimated 14 GW of existing grid transfer capacity without requiring protracted environmental right-of-way permitting for new corridors.
