Illinois Energy Market Update | August 2026
Businesses in Illinois may continue to see elevated electricity prices as higher capacity costs put pressure on them. PJM capacity costs remain a major concern for businesses, and the market is facing another major shortfall as electricity demand continues to grow. Data centers were identified as a major source of this demand, while the Illinois Power Agency’s 2026 procurement plan projects 14.1% annual growth for Ameren Illinois’ industrial load. Transmission congestion costs have also increased by 43% during the first half of the year compared to the same period last year. Illinois businesses should pay close attention to conditions as pricing and energy trends influence future electricity costs.
