Grid Infrastructure as the Binding Constraint

Even with accelerated clean energy deployment, the limiting factor for decarbonization is transmission infrastructure. The U.S. electricity grid needs approximately $2.5 trillion in upgrades to support the level of renewable integration needed for the 2035 clean electricity goal.

Core Takeaway

The bill creates a new Transmission Investment Credit providing a 20% credit for qualifying transmission projects — a potentially transformative incentive for projects that have been stalled by insufficient return on investment.
