Summary
Edison International, through its subsidiary Midwest Generation, LLC, has reached an agreement in principle with the Illinois Environmental Protection Agency regarding emissions reductions at its Illinois coal-fired power plants. This agreement aims to provide clarity on future compliance requirements for mercury, nitrogen oxide (NOx), and sulfur dioxide (SO2) emissions through 2018, contingent on regulatory approval. The implementation will involve significant capital expenditures for environmental retrofits or potential unit shutdowns over three phases, addressing mercury by 2009, NOx by 2011, and SO2 between 2012 and 2018.
Key Highlights
- 1Agreement in principle reached with Illinois EPA for emissions reductions at Midwest Generation's coal plants.
- 2Agreement covers mercury, nitrogen oxide, and sulfur dioxide emissions through 2018, subject to regulatory approval.
- 3Phase 1 (by 2009): Mercury reduction via activated carbon injection, estimated capital expenditure of $60 million.
- 4Phase 2 (by 2011): NOx controls installation on several units, estimated capital expenditure of $450 million.
- 5Phase 3 (2012-2018): SO2 reduction through controls or unit shutdowns, with estimated capital expenditure ranging from $2.2 billion to $2.9 billion.
- 6Implementation requires regulatory proceedings and may involve environmental retrofits or plant unit retirements.
- 7Actual capital expenditures may vary significantly from estimates due to various factors including technology assessment and market outlook.
Frequently Asked Questions
The primary focus is the announcement of an agreement in principle between Edison International's subsidiary, Midwest Generation, LLC, and the Illinois Environmental Protection Agency concerning future emissions reductions at its Illinois coal-fired power plants.
The estimated capital expenditures are approximately $60 million for mercury controls, $450 million for nitrogen oxide controls, and an estimated $2.2 billion to $2.9 billion for sulfur dioxide compliance, depending on the chosen compliance strategy (retrofits vs. shutdowns).
The agreement outlines three phases: mercury reduction by 2009, nitrogen oxide controls by the end of 2011, and sulfur dioxide reduction between 2012 and 2018.
The agreement is an 'agreement in principle' and requires further regulatory proceedings for approval. There is no assurance that all required approvals will be received. Additionally, the final capital expenditures could vary substantially from current estimates due to various factors, including the choice between retrofits and unit shutdowns for SO2 compliance.
