Illinois can build on its progress to date and achieve greater reductions by taking the following four actions:

• Energy efficiency. Remove the spending cap on the energy efficiency standard so the utilities can fully meet their savings targets, which ramp up to 2 percent annually starting by 2015.


• Renewable energy. Ensure that alternative compliance payments, which alternative retail electric suppliers must use to meet half of their requirement under the renewable energy standard, are used to increase investment in renewable energy. 


• Existing natural gas plants. Increase the use of combined cycle plants to 75 percent, which is closer to the levels they’re capable of achieving than the 18 percent they at which they ran in 2013.


• Coal plant efficiency. Adopt low-cost operational improvements and best practices at coal plants.

Illinois could meet—or even exceed—its mass-based emission targets by adjusting or removing the spending cap on efficiency while increasing the target to achieve about 20 percent cumulative energy savings by the end of 2025 and increasing the renewable energy standard to 35 percent of the state’s sales by 2030, in line with the state’s bipartisan Clean Jobs Bill. Doing so would cut CO2 emissions by 76 percent below 2012 levels by 2030.

Illinois can develop an implementation plan that maximizes the economic benefits to the state and achieves emission reductions cost-effectively by:

1. Adopting a market-based carbon pricing program, which encourages cost-effective emission cuts and generates revenue that can be used for public investments or reducing taxes. The CPP encourages states to trade credits without formally joining a trading program.  If Illinois surpasses its CPP target through the actions described above, it could generate an average of over $300 million per year in revenue between 2022 and 2030 from out-of-state sources if emission allowances trade at $10 per short ton.


2. Investing in energy efficiency. Efficiency is one of the most cost-effective tools for Illinois to cut its emissions while saving money for residents. The state’s efficiency standard is estimated to save customers over $1 billion per year in 2025.

Even with the stay on the Clean Power Plan, Illinois has every reason to move forward with its transition to a low-carbon power sector. By expanding its clean energy policies and addressing current barriers, Illinois would be ahead of the game when EPA is able to move forward with regulating carbon pollution from power plants. At the same time, the state would be able to scale up the benefits from these policies, reduce the need to invest in other states’ power sectors, and achieve deeper carbon emissions reductions more cost-effectively.
