Following the Environmental Protection Agency’s (EPA) June 2014 issuance of its draft Clean Power Plan (CPP) – which would cut by 30 percent existing power-plant carbon dioxide emissions from 2005 levels by 2030 – Southwest Power Pool (SPP) performed a reliability impact assessment evaluating the impacts of the plan’s projected generation unit retirements on the reliability of the SPP region’s bulk power system. SPP published its assessment and submitted comments based on that assessment to the EPA on October 9, 2014.
In January 2015, SPP’s Strategic Planning Committee (SPC) directed staff to proceed with a second CPP assessment to identify impacts on existing and planned resources, identify at-risk generation in SPP’s region, evaluate resource planning measures to facilitate compliance with the proposed carbon emission goals, and estimate compliance costs. The SPC instructed staff to first assess compliance with the CPP under a regional approach, then to assess compliance under individual state-by-state approaches. SPP published a report of its regional compliance assessment March 30, 2015. This report includes information and results from the state-by-state compliance analysis along with a comparison of the previously published regional compliance assessment, which was slightly revised based on information discovered through preparation of the state compliance analysis
