IL SB3341

Amends the Environmental Protection Act to exempt black start facilities from greenhouse gas emission limits, defining black start facilities as generating units capable of operating independently without external electrical supply and essential to electric grid restoration after major system disturbances.

Requires non-public coal and oil-fired electric generating units to reduce CO2e and copollutant emissions to zero by January 1, 2030.

Requires public coal-fired units to achieve zero CO2e emissions by December 31, 2045, with a 45% reduction by January 1, 2035, or face unit retirement by June 30, 2038.

Establishes tiered deadlines for natural gas units (2030-2045) to eliminate CO2e and copollutant emissions through retirement or conversion to 100% green hydrogen technology, with black start facilities limited to 3,200 operating hours annually.

Mandates annual emissions reporting and requires Environmental Protection Agency, Illinois Power Agency, and Illinois Commerce Commission to jointly prepare five-year reliability assessments, with authority to develop mitigation plans delaying emission reductions only if necessary to maintain grid reliability.
