State and Utility Pollution Reduction Calculator Version 2 (SUPR 2)

Updated February 1st. If you've already downloaded SUPR 2, please download this updated version.

EPA’s Clean Power Plan allows states to pick from many pollution-reducing technologies and policies—including energy efficiency—when designing their compliance plans. What are the costs and emissions benefits of these various compliance options? ACEEE has developed the State and Utility Pollution Reduction Calculator Version 2 (SUPR 2) to help states find the answers. Users can choose from 19 policies and technologies to build their state's compliance scenario, including energy efficiency, renewable energy, nuclear power, emissions control, and natural gas. SUPR 2 shows them how much the scenario will cost and what they will get for that investment. This tool is an update to the SUPR calculator, originally released by ACEEE in April 2015. SUPR 2 reflects the new data and requirements in EPA’s Clean Power Plan final rule.
