A bipartisan group of Illinois lawmakers gathered at the State Capitol last week to unveil a legislative package aimed at protecting energy affordability and reliability as Illinois moves more toward electrification.

The bipartisan set of lawmakers noted that Illinois is already facing rising energy costs and growing concerns about grid stability. A recent state resource adequacy study warned of tightening capacity margins and potential reliability challenges in the coming years if infrastructure decisions are not carefully managed.

According to them, the package is designed to maintain Illinois’ existing energy infrastructure, prevent unnecessary cost burdens on families and small businesses, and protect vulnerable and low-income residents from higher utility bills.

The legislation includes:

• Senate Bill 3970 and Senate Bill 3979, which require thorough studies and reviews of customer bill impacts before large-scale gas transition projects are approved.
• Senate Bill 3929, which extends closure dates set in CEJA for power plants by 10 additional years.
• Senate Bill 4028, which modernizes outdated interconnection rules that contribute to project delays and inconsistent upgrade costs.

Natural gas continues to play a critical role in Illinois’ energy system by providing reliable, on-demand power that stabilizes the grid during peak demand and extreme weather conditions. This bipartisan package seeks to promote balanced energy policy grounded in affordability, infrastructure readiness, and long-term grid stability.
