Incentives background

Senate Bill 1592 was signed into law in August 2007. This statute created the Energy Efficiency Portfolio Standard (EEPS) and a Renewable Portfolio Standard (RPS) and is among the most ambitious clean energy legislation in the nation. The EEPS required Illinois utilities to reduce overall electric usage by 0.2% of demand in 2008, escalating to 2.0% by 2015. The RPS will require utilities to supply 2% of their power from renewable energy sources by 2008 for certain “eligible customers” and that target will escalate to 25% by 2025.

This law creates a substantial budget for programs and incentives to reduce electrical energy usage and demand for customers of ComEd and Ameren Illinois. During the first year, approximately $50 million was devoted to various sectors of utility customers. ComEd and Ameren Illinois focused approximately $38 million on residential, commercial and industrial customers and the Illinois Department of Commerce and Economic (DCEO) utilized about $12 million on the low income and public sectors. During the second year, over $100 million was available for programs and by the third year, over $150 million. This legislation is, by far, the largest opportunity Illinois has had for energy efficiency and demand reduction.
