Illinois Executive Order for Nuclear Energy Development

Illinois Governor has issued Executive Order 2026-01, effective February 18, 2026, to expedite the development of new nuclear energy generation within the state. The order is a response to the state's Climate and Equitable Jobs Act (CEJA) and the Clean and Reliable Grid Affordability Act (CRGA), which set a goal of 100% clean energy by 2050 and removed previous restrictions on new nuclear power plants. The order also addresses findings from a Resource Adequacy Study indicating potential power shortages in the coming decade due to increased demand and grid interconnection queues.

This executive order signifies a substantive shift in Illinois' energy policy, actively promoting nuclear energy as a component of its clean energy strategy. Energy companies operating in or looking to develop in Illinois should be aware of the new policy direction and potential opportunities. While no specific compliance deadlines or penalties are detailed in this initial order, regulated entities should anticipate further regulatory action and planning processes related to integrated resource planning and grid interconnection as the state implements its clean energy objectives.
