We Energies Clean Air Strategy Navigating the Environmental Regulatory Landscape Kris McKinney Wisconsin Public Utility Institute Seminar March 29, 2011 We Energies - Retail Electric and Gas Utilities Largest electric and gas company in Wisconsin 1.1 million electric customers 1.0 million natural gas customers Corporate Strategy Power the Future Retire/repower coal power plants Build new, more efficient natural gas and coal power plants Add emission controls at coal power plants Add more energy efficiency and renewable energy generation Clean Air Strategy Power the Future commitments identified environmental planning in 2000 Submitted a proposal jointly with WDNR to USEPA in 2000 under federal eXcellence in Leadership innovation program Signed the Wisconsin Multi-Emission Cooperative Agreement (MECA) with WDNR in 2002 Pursued consent decree (EPA Agreement) with USEPA and USDOJ in early 2003 Power Plants - Varying Degrees of Risk Our power plants face varying degrees of environmental regulatory risk depending on the plant’s: Air emission control equipment Water intake structures Coal combustion product management Landfill design and performance characteristics Geographic location What Have We Done So Far? We are taking and have taken numerous actions in response to environmental issues Entering into agreements Repowering coal to natural gas Retiring older, less efficient coal Adding air quality controls Upgrading water intake structures Engaging in a coal combustion product beneficial use program Not using ash ponds Implementing advanced upgrades to operating landfills Construction Schedule Emission Controls & Capacity Additions POWER PLANT & UNIT(S) 2002 2003 2004 2005 2006 2007 2008 2009 Oak Creek 5-6 SO2 & NOx Controls Pleasant Prairie 1 SO2 & NOx Controls NOx Controls Mercury Controls SO2 Controls Presque Isle 1-2 Mercury Controls Retired Presque Isle 3-4 Presque Isle 5-6 Presque Isle 7-9 Retired NOx Controls PM Controls NOx Controls Mercury Controls Valley 1-2 Common (10 Units) Port Washington 1-2 Elm Road 1-2 Renewables Energy Efficiency 2011 2012 SO2 & NOx Controls Oak Creek 7-8 Pleasant Prairie 2 2010 NOx Controls PM Monitors Mercury Monitors REPOWER COAL TO COMBINED CYCLE NATURAL GAS NEW SUPERCRITICAL PULVERIZED COAL 5% OF ENERGY FROM RENEWABLES BY 2011 55 MW OF ENERGY EFFICIENCY 2013 We Energies Emission Trends We Energies Actual & Projected Emissions Nitrogen Oxides & Sulfur Dioxide 1.2 125 Emission Rate (lb/mmBtu) 100 0.8 75 0.6 0.4 50 0.2 25 0.0 0 2000 2002 2004 2006 2008 2010 2012 The capital cost of achieving these emission reductions SO2 NOx $1.2 billion is estimated to be approximately Mass Emissions_ (1000 tons) 1.0 Where do we go from here? Our smallest coal power plants face the most significant decisions in the next few years Compliance decisions at these plants are complicated by potential reliability and steam customer impacts Valley and Milwaukee County are must-run coal cogeneration plants that serve a limited number of steam customers Presque Isle is a must-run plant with respect to the transmission grid due to geographic constraints Questions? ?
