A new bill authored by State Rep. Halbrook in the Illinois House seeks to extend deadlines for emission reductions and adjust permit requirements for certain power plant equipment, according to the Illinois State House.

The bill, introduced as HB4123 on Sep. 16, 2025, during the general assembly session 104, was summarized by the state legislature as follows: "Specifies that the amendatory Act may be referred to as the Save Our Power Plants Act. Amends the Environmental Protection Act. In a provision concerning the regulation of greenhouse gases, extends by 15 years the deadlines for attaining specified emission reductions. Effective immediately."

The following is our breakdown, based on the actual bill text, and may include interpretation to clarify its provisions.

In essence, the bill, known as the Save Our Power Plants Act, amends the Environmental Protection Act to address deadlines for emission reductions. It extends these deadlines by 15 years and stipulates that an air pollution construction or operating permit will not be needed for equipment or sites not subject to greenhouse gas regulation. This provision does not exempt owners from other regulatory obligations. The bill outlines specific emission targets and timelines for electric generating units (EGUs) and large greenhouse gas-emitting units, mandating zero emission reductions by various dates depending on the type and location of units. It also involves the Environmental Protection Agency, Illinois Power Agency, and the Illinois Commerce Commission in ongoing reporting and joint assessment of renewable energy progress, emissions reductions, and energy resource adequacy. The Act is effective immediately upon becoming law.

Halbrook has proposed another 18 bills since the beginning of the 104th session.

Bills in Illinois follow a multi-step legislative process, beginning with introduction in either the House or Senate, followed by committee review, floor debates, and votes in both chambers before reaching the governor for approval or veto. The General Assembly operates on a biennial schedule, and while typically thousands of bills are introduced each session, only a fraction successfully pass through the process to become law.

Halbrook, a Republican, was elected to the Illinois State House in 2023 to represent the state's 107th House District, replacing previous state representative Blaine Wilhour.
