Over 70% of the US Grid Is More Than 25 Years Old. Utilities Are Starting to Catch Up
According to Shale Magazine, more than 70% of the US electricity grid is over 25 years old, with an estimated 31% of transmission and 46% of distribution infrastructure already near or past their intended lifespans. The Bipartisan Infrastructure Law allocated $30 billion for grid upgrades, including $2.3 billion to states for grid resiliency, while the Department of Energy has outlined a pathway for deploying advanced transmission technologies including advanced conductors and dynamic line rating.
What It Means for Subcontractors
- Replacement costs for aging transmission infrastructure are estimated at $10 billion per year, according to advisory firm the Brattle Group, signaling sustained demand for utility construction crews and equipment in the years ahead.
- New renewable energy projects in rural areas require significant transmission line extensions beyond existing urban corridors, opening work in regions where utility construction activity has historically been limited.
- Fragmented grid ownership across hundreds of companies means subcontractors should expect to pursue contracts through multiple utility clients and regional operators rather than a single federal program.
