Energy Efficiency Resource Standards
Electricity
Illinois enacted an energy efficiency resource standard (EERS) in 2007 for investor owned electric utilities, with efficiency programs beginning in 2008. The law required 0.2% savings through efficiency of energy delivered in 2009 and ramps-up to 2.0% by 2015 and every year thereafter.
Natural Gas
Illinois enacted an energy efficiency resource standard (EERS) for investor owned natural gas utilities in 2009 and programs under the standard will begin in 2010. The law requires 0.2% savings through efficiency of energy delivered by 2012 and ramps-up to 1.5% savings by 2019 and every year thereafter.

Decoupling
Illinois does not have any policies to support decoupling; however, some utilities have been approved for revenue-per-customer pilot programs in February of 2008.

Building Energy Codes
Residential
In May of 2009 the Illinois General Assembly passed the Energy Efficient Building Act, which enacts a statewide residential building code and compels the state to adopt the most recently published form of the International Energy Conservation Code (IECC), currently the 2009 IECC. The Act was signed into law by Governor Pat Quinn in August of 2009. The code sets a minimum standard of energy efficiency for all new residential construction and applies to any major renovations or upgrades of existing buildings. The Illinois Capital Development Board is currently finalizing the new code for implementation, which by law must be implemented no later than the end of September, 2010.
Commercial
The 2009 IECC serves as the statewide energy code for all new commercial construction and major renovations or upgrades of existing buildings; this standard of minimum energy efficiency requirements was set forth in the Energy Efficient Commercial Building Act which was later amended to include residential construction and became the Energy Efficient Building Act.

Appliance Standards
Illinois has not enacted any energy efficiency standards for appliances that are not mandated in the federal Energy Policy Act of 2005.
