The Future of Illinois Energy: Clean Energy Transition Act and Its Effects on Rates
The Climate and Equitable Jobs Act (CEJA), signed into law in 2021, represents the most significant energy legislation in Illinois history. This landmark law sets Illinois on a path to 100% clean energy by 2050 and has profound implications for commercial electricity rates, business incentives, and energy procurement strategies.

Decoding CEJA: What Every Illinois Business MUST Know About the Clean Energy Act
The Climate and Equitable Jobs Act establishes an ambitious roadmap for transforming Illinois' energy sector. Understanding its key provisions helps businesses anticipate changes and position themselves advantageously.
CEJA's Core Objectives
CEJA sets aggressive targets for decarbonizing Illinois' electricity sector:
- 2030: 40% reduction in power sector carbon emissions from 2005 levels
- 2035: 100% carbon-free electricity generation
- 2050: 100% clean energy economy-wide
These targets will be achieved through a combination of renewable energy expansion, nuclear plant preservation, and gradual phase-out of fossil fuel generation.
Key Provisions Affecting Commercial Customers
Nuclear Plant Subsidies
CEJA provides financial support to keep Illinois' nuclear plants operating. Nuclear generates about 50% of Illinois' electricity and is considered essential for grid reliability during the clean energy transition. Commercial customers contribute to these subsidies through small charges on their bills.
Renewable Energy Expansion
The law significantly expands the Illinois Renewable Portfolio Standard, requiring utilities to source increasing percentages of power from wind, solar, and other renewables. This drives major investments in renewable generation infrastructure.
Coal and Gas Plant Phase-Out
CEJA establishes a timeline for reducing and eventually eliminating fossil fuel generation. Private coal plants must close by 2030, and municipal coal plants by 2045. Gas plants face gradual emission reductions leading to closure or carbon capture requirements.
Electric Vehicle Infrastructure
The law includes provisions for expanding EV charging infrastructure, creating opportunities for businesses to participate in the electrification of transportation.
Equity and Workforce Provisions
CEJA includes significant provisions for environmental justice and workforce development:
- Prioritization of clean energy investments in disadvantaged communities
- Job training programs for clean energy careers
- Enhanced energy assistance for low-income households
- Community solar programs targeting underserved populations
Will Your Commercial Energy Bill Skyrocket? Unpacking CEJA's Real Impact on Rates
The question every Illinois business owner asks: how will CEJA affect my energy costs? The answer is nuanced, with both upward pressures and potential savings opportunities.
Factors That May Increase Costs
Massive investments in renewable generation, grid modernization, and transmission infrastructure will be recovered through rates over time.
Supporting nuclear plants adds charges to customer bills, though this cost is offset by the plants' contribution to price stability.
Maintaining grid reliability with more variable renewable generation requires investments in storage and flexible resources.
Energy efficiency programs, workforce development, and equity initiatives are funded through utility charges.
Factors That May Reduce Costs
Once built, wind and solar have no fuel costs, providing long-term price stability compared to fossil fuel volatility.
Enhanced efficiency programs help businesses reduce consumption, offsetting rate increases with lower usage.
Solar, wind, and battery costs continue falling, reducing the cost of new clean energy infrastructure.
Clean energy reduces health and environmental costs not reflected in energy prices but borne by society.
Expert Projections
According to analysis from the Illinois Commerce Commission and independent researchers:
- Near-term rate impacts are expected to be modest, in the range of 1-3% annually
- Long-term impacts depend heavily on technology costs and federal policy
- Businesses that actively manage energy can mitigate or offset rate increases
- The transition creates new opportunities for cost savings through incentives
The Nuclear Factor
Illinois' nuclear plants provide about half the state's electricity and nearly all of its carbon-free power. CEJA's subsidies keep these plants operating, which:
- Prevents replacement with higher-cost alternatives
- Maintains grid reliability during renewable buildout
- Provides price stability compared to gas-dependent markets
Beyond the Bill: 3 Ways to Leverage CEJA Incentives for a Competitive Advantage
CEJA creates significant opportunities for businesses willing to embrace clean energy. Forward-thinking companies can turn the transition into a competitive advantage.
Opportunity 1: Enhanced Solar and Storage Incentives
CEJA dramatically expands Illinois' solar incentive programs:
- Illinois Shines Expansion: Increased capacity and funding for commercial solar projects
- Higher REC Values: Potentially more valuable Renewable Energy Credits for new installations
- Storage Incentives: New programs for battery storage paired with solar
- Community Solar Growth: Expanded opportunities for subscription-based solar
Businesses that act early can lock in attractive incentives before capacity blocks fill. See our guide to renewable energy options in Illinois for details.
Opportunity 2: Energy Efficiency Program Funding
CEJA increases funding for utility energy efficiency programs, expanding available rebates and incentives:
- Equipment Rebates: Enhanced incentives for high-efficiency HVAC, lighting, and controls
- Custom Projects: Funding for unique energy-saving investments
- Technical Assistance: Free or subsidized energy audits and engineering support
- Building Benchmarking: Resources for tracking and improving building performance
Opportunity 3: Electrification and EV Infrastructure
CEJA supports the electrification of transportation, creating opportunities:
- EV Charging Incentives: Rebates for installing workplace and fleet charging
- Make-Ready Programs: Utility investment in electrical infrastructure for charging
- Fleet Electrification: Support for transitioning commercial vehicles
- Customer Attraction: EV charging can attract customers and employees
Strategic Advantage
Businesses that proactively embrace clean energy can reduce costs, attract sustainability-minded customers and employees, meet corporate ESG goals, and position themselves as leaders in their markets.

Near-term rate impacts are expected to be modest. While infrastructure investments will add costs, declining renewable technology costs and efficiency gains provide offsetting factors. Businesses that actively manage energy and leverage incentives can often offset or exceed any rate increases.
CEJA doesn't require individual businesses to use renewable energy. The law applies to the overall electricity sector. However, businesses can voluntarily choose green energy options and access incentives for clean energy investments. The grid will become increasingly clean regardless of individual choices.
CEJA primarily addresses the electricity sector. Natural gas for heating and industrial processes is not directly regulated by CEJA, though broader climate policy may affect gas use over time. Electrification of heating is encouraged but not mandated for commercial buildings.
Yes. CEJA expands utility efficiency programs available to businesses of all sizes. Small commercial solar projects can access Illinois Shines incentives. Community solar offers renewable energy access without installation. Contact your utility or an energy advisor for specific programs.
