- Illinois Central Grid Transformation Program Approved, Ushering in Renewable Energy Era
SPRINGFIELD, IL (July 2, 2025) – In a move poised to reshape Illinois’ energy landscape, the Illinois commerce Commission (ICC) has given the green light to the Central Illinois Grid Transformation program, spearheaded by Ameren Transmission Company of Illinois (ATXI) and Ameren Illinois. This ambitious project will modernize and expand the state’s energy grid through the construction of 380 miles of new and upgraded transmission lines [1].
ICC Approves Landmark Energy grid Modernization
The ICC’s approval grants a certificate of public convenience and necessity for the 380-mile initiative. The project will create vital connections across Illinois, linking the energy grid from Indiana to iowa and Missouri. This expanded grid aims to bolster reliability and facilitate access to affordable renewable energy resources.
Did You Know? The Illinois Commerce Commission also regulates telecommunications, natural gas, and water industries within the state.
benefits of the Central Illinois Grid Transformation program
The Central illinois Grid Transformation Program is a key component of the Midcontinent independent System Operator’s (MISO) Long-Range Transmission Plan (LRTP) Tranche 1 project, a multi-state effort across the Upper Midwest. Over the next 20 years, Illinois is projected to reap up to $2.8 billion in financial benefits from this program [2].
Elizabeth Wheeler, Senior Counsel and Director of Regulatory Advocacy at Clean Grid Alliance, emphasized the importance of such infrastructure projects. “Infrastructure projects like the Central Illinois Grid Transformation Program are critical to ensuring low-cost, reliable energy can flow freely across the region,” Wheeler stated.”Modernizing our electric grid with new and upgraded transmission lines is absolutely necesary to support a secure economic future for Illinois.”
Stakeholders Celebrate a Cleaner Energy Future
The decision was met with enthusiasm from environmental and consumer advocacy groups.
“The Central Illinois Grid Transformation Program will deliver a more reliable, affordable energy future for Illinois residents,” said Curt Stokes, Senior Attorney at Environmental Defense Fund. “this project is crucial for grid reliability, unlocking access to affordable renewable energy and delivering billions in benefits from lower carbon emissions.”
Jim Chilsen, Communications Director of the Citizens Utility Board, echoed this sentiment. “We thank the Illinois Commerce Commission for approving this transmission program,which will help advance Illinois’ goal of securing clean and affordable energy for its residents,” Chilsen said. “Smart, cost-effective transmission planning is critical to the clean energy transition, and an absolute must to help Illinois achieve a clean, affordable energy future for all electric customers.”

MISO’s Long-Range Transmission Plan: A Regional Impact
MISO’s Tranche 1 portfolio of LRTP projects, approved in July 2022, is expected to generate $37 billion in regional economic benefits over 20 years. These projects aim to enhance grid reliability and facilitate the integration of new, low-cost renewable energy resources. The Tranche 1 transmission lines are considered “least-regrets” projects, addressing long-standing reliability and efficiency concerns across the regional electricity grid.
| Project | Expected Benefits | Key goal |
|---|---|---|
| Central Illinois Grid Transformation Program | Up to $2.8 Billion for Illinois (over 20 years) | Modernize grid, improve reliability, enable renewable energy access |
| MISO LRTP tranche 1 | $37 Billion Regionally (over 20 years) | Enhance grid reliability, integrate renewable energy |
