WASHINGTON, D.C. — U.S. Sen. Martin Heinrich (D-N.M.), a member of the Senate Energy and Natural Resources Committee, introduced legislation to incentivize the construction of new electric transmission infrastructure to meet our decarbonization goals and support the energy transition, while building the clean energy workforce of tomorrow. U.S. Rep. Steven Horsford (D-Nev.) will introduce companion legislation in the House.
The Grid Resiliency Tax Credit Act will provide a targeted 30 percent investment tax credit (ITC) to support investments in large-scale transmission projects and grid enhancing technologies that help to provide consumers with more affordable and reliable electricity.
“To meet our nation’s full potential as a global leader in the clean energy transition and to replace rapidly aging electric infrastructure, we are going to need to invest in building many more transmission lines,” Heinrich said. Over the last decade and a half, tax incentives have sent a powerful signal to private investors to put their capital behind new wind and solar projects. We need to send a similarly strong and long-term financial signal that it is worth the time and effort it takes to steer massive transmission infrastructure projects all the way from planning to construction.”
The targeted approach in the Grid Resiliency Tax Credit Act would incentivize regionally-significant transmission projects and critical transmission subcomponents and grid-enhancing technologies while avoiding incentives for smaller local transmission projects or routine asset replacements.
Overhead, underground, or offshore transmission projects that would qualify for the Grid Resiliency Tax Credit include:
- New Transmission: Projects that (1) cross no fewer than 2 States or not less than 150 continuous miles or the Outer Continental Shelf (2); and not less than 750 megawatts and 345 kilovolts in capacity; or (3) not less than 100 kilovolts and include an advanced transmission conductor.
- Modifications to Existing Transmission: Projects that increase transmission capacity by at least 500 megawatts.
- Transmission Property Used for Interconnection or Generator Tie-Lines: Projects that are not less than 230 kilovolts in capacity and used as generator interconnection tie-lines for interconnecting new generation or for network upgrades.
- Subcomponents: Investments in certain subcomponents, including transformers necessary for the operation of new or modified transmission facilities.
- Grid-Enhancing Technology: Investments in grid-enhancing technology on new and existing transmission facilities for increasing the capacity or line rating.
The Grid Resiliency Tax Credit Act would provide a 10-year tax credit. Starting in 2024, all qualifying transmission projects that are placed in service would qualify for the credit and any qualifying project that starts construction before the end of 2033 could claim the credit. Further, taxpayers would be able to monetize the credit under the Inflation Reduction Act’s new tax-credit transferability provisions.
The American Council on Renewable Energy projects that a 30 percent investment tax credit for regionally-significant transmission projects would add enough new capacity to the grid to integrate an additional 30,000 megawatts of new renewable energy generation. New transmission lines supported by the tax credit would also create over 650,000 clean energy jobs, deploy more than $15 billion in private capital investment, and provide American consumers with $2.3 billion in energy cost savings.
