Generation in Illinois
The Investments that Power Illinois
Baseload Generation Ensuring Reliable and Affordable Energy
Designed to run almost all the time, a baseload is provided by large plants using thermal energy to generate electricity. Nuclear and coal make up the majority of baseload generation in Illinois. No current technology can replace baseload generation.
Intermediate Generation
Unlike baseload, intermediate generation is designed to turn on and off throughout the year to accommodate predictable and seasonal changes in demand. Natural gas and coal make up most of Illinois’ intermediate generation.
Peak Generations
Peaking generation is designed to run for short periods of time to meet the most extreme demand changes throughout the day. These plants can be quickly dispatched and provide power on a moments notice. Most peaking plants are powered by natural gas in Illinois.
Intermittent Generation, Renewables
Intermittent generation is designed to minimize the environmental impact of electric generation. It relies upon environmental conditions to provide power. When available, intermittent generation helps to control cost at peak times and provide for a cleaner and healthier environment.
