ENERGYWIRE: Can the Midwest build transmission fast enough for an evolving grid?

Without billions of dollars in high-voltage power lines, the region may not have enough electricity to meet demand in extreme weather. The Midwest’s grid operator is expected soon to greenlight the country’s largest-ever investment in new power lines to help states and utilities transition to renewable energy. It’s not nearly enough. Experts say that the roughly $20 billion effort, while unprecedented, may be half of what’s needed to support the region’s rapidly evolving power mix.

Regulatory and Construction Updates

Grain Belt Express is a regulated public utility in Kansas, Missouri, Illinois and Indiana and is regulated by the Federal Energy Regulatory Commission (FERC).    

Project Phasing & Construction Timeline

Invenergy Transmission is proposing to construct Grain Belt Express in two phases.   

Phase 1 extends between the line’s Kansas and Missouri interconnection points. Construction-related activities on Phase 1 is anticipated to begin as soon as 2025.

Phase 2 extends between the line’s mid-point Missouri converter station and Indiana interconnection point. A schedule for Phase 2 has not yet been announced but will follow Phase 1. Grain Belt Express remains fully committed to both project phases.

Federal Approvals & Reviews

U.S. Department of Energy Loan Programs Office Environmental Review 

The U.S. Department of Energy (DOE) Loan Programs Office has initiated the federal environmental review and permitting process for the proposed Grain Belt Express Phase 1 (from the line’s Kansas to Missouri interconnection points). An Environmental Impact Statement for the project will be developed and issued for the project, which includes a 75-day public scoping period that was initiated on December 16, 2022. Visit the DOE’s Environment Impact Statement website to learn more and provide input. 



Grain Belt Express Phase 1 received Title 41 of Fixing America’s Surface Transportation Act (FAST-41) designation by the Federal Permitting Improvement Steering Council, signifying its national priority importance to improving grid reliability and energy affordability, particularly in the Midwest region. Grain Belt Express was posted to the permitting dashboard February 20, 2024.

Federal Energy Regulatory Commission

The Federal Energy Regulatory Commission (FERC) has authorized Grain Belt Express to sell transmission capacity to potential customers of the project, including utilities and other load-serving entities or clean energy generators, and to negotiate agreements for 100% of the project’s capacity. Generator interconnection to Grain Belt Express will be subject to the requirements of the project’s FERC-approved open access transmission tariff. 

State Approvals & Reviews


The Kansas Corporation Commission extended Grain Belt Express’s certification as a transmission-only public utility in 2019 with an approved route and a Certificate of Public Convenience and Necessity (CPCN) to construct the approximately 380-mile Kansas portion of the project.

Grain Belt Express received its certificate of convenience and necessity from the Missouri Public Service Commission (MPSC) in 2019.  

As a public utility in Missouri, Grain Belt Express already has long-term transmission service agreements with the Missouri Public Energy Pool (MOPEP) and other Missouri municipal utilities that will provide clean energy and $12.8 million in annual energy savings for at least 39 municipal utilities across Missouri.  

In August 2022, Grain Belt Express filed an amendment request with the MPSC seeking approval to increase the total delivery capacity of the project, bringing five times more energy to Missouri than originally approved in 2019. The amendment request to the Certificate of Convenience and Necessity, which includes identification of a final Tiger Connector route in Missouri, was approved by the MPSC on October 12, 2023.

Grain Belt Express’s additional commitment to deliver more power to Missouri could not have come at a better time for businesses in our region who are facing increased risk for outages and higher energy bills due to more demand and less energy production.
Ray McCarty, Associated Industries of Missouri
You can’t have a strong business climate if manufacturers are worried about the reliability and cost of their power supply. There’s no question, manufacturers and the communities they support across our region will see significant benefits thanks to this essential investment.
Mark Denzler, President & CEO, Illinois Manufacturers’ Association
[Grain Belt Express] will also be capable of moving electricity both directions, which could have helped mitigate the electricity crisis that hit the United States earlier this year. ‘Lines like Grain Belt Express could have been the savior’
Kansas City Star,  April 12, 2021
Our area has been in need of transmission upgrades for some time. The Tiger Connector plan will be good for everyone in our area
