rooftop solar panels), alternative energy sources, and petitions to municipalize (Iowa) as well as service territory expansions by municipal utilities through annexations (Wisconsin). However, IPL and WPL attempt to attract new customers into their service territories in an effort to keep energy rates low for all its customers.
Renewable Energy Standards - As discussed in greater detail below, the states in which IPL and WPL operate have RES, which establish the amount of energy electric utilities or service providers must supply from renewable resources.
IPL - IPL has requirements to comply with RES in both Iowa and Minnesota and primarily relies upon RECs generated from the wind projects it owns and renewable energy acquired under PPAs to meet such requirements. IPL allocates its portfolio of RECs between its Iowa and Minnesota jurisdictions based on a load-ratio share. IPL has excess RECs in Iowa and a shortfall of RECs in Minnesota. However, the excess RECs in Iowa are much larger than the Minnesota shortfall partially due to the relatively small amount of IPL's load served in Minnesota compared to Iowa. IPL is permitted to use its surplus of RECs in Iowa to meet its deficit of RECs in Minnesota. IPL expects to meet both its Iowa and Minnesota renewable energy requirements on a system-wide basis without the need to purchase additional RECs. Iowa - IPL is required to purchase or own 49.8 MW of nameplate capacity from alternate energy or small hydro facilities located in its service area. IPL currently exceeds this Iowa requirement. Minnesota - IPL's total Minnesota retail electric sales supplied with renewable energy sources must be at least 12% currently and 17% by 2016, 20% by 2020, and 25% by 2025. Utilities in Minnesota may meet the requirements of the RES with renewable energy generated by the utility, renewable energy acquired under PPAs, or the use of accumulated or acquired RECs. IPL has met the 12% requirement and currently expects to satisfy future Minnesota RES requirements with its current wind generation and wind PPAs, supplemented as needed by acquiring additional RECs from its anticipated Iowa excess supply.
In addition to the above Minnesota requirement, IPL's total Minnesota retail electric sales supplied with solar power must be at least 1.5% by 2020. IPL currently estimates that approximately 10 MW of solar power would be needed for compliance with this requirement by 2020.
WPL - The Wisconsin RES requires WPL to increase the portion of its total Wisconsin retail electric sales supplied by renewable energy sources above a benchmark of average retail sales from renewables in 2001, 2002 and 2003. The RES required a 2% increase above the benchmark by 2010 and will require a 6% increase above the benchmark by 2015. Based on this RES, WPL was required to supply a minimum of 5.28% of its total Wisconsin retail electric sales with renewable energy sources by 2010 and will be required to increase this amount to 9.28% by 2015. WPL may reach the RES with renewable energy it generates, it acquires under PPAs or through the use of renewable resource credits.

For example, the Consent Decree resulted from allegations originally raised by the Sierra Club that WPL violated various provisions of the Clean Air Act. If we are unsuccessful defending or settling such litigation by governmental agencies, citizen groups, or individuals, we could be subject to restrictions or prohibitions on operating our generation facilities, costly upgrades to our generating facilities, payment of damages or fines, requirements to complete other beneficial environmental projects, and litigation costs, all of which could be material. An adverse result in such legal actions could have a material adverse impact on our financial condition and results of operations. In addition, we may also be subject to third party environmental claims relating to property damage or personal injury that arise from our operations.
We are subject to existing and potential future governmental mandates to provide customers with renewable energy and energy conservation offerings. These mandates are designed in part to mitigate the potential environmental impacts of utility operations. Failure to meet the requirements of these mandates may result in fines or penalties, which could have a material adverse effect on our results of operations. If our regulators do not allow us to recover all or a part of the costs incurred to comply with the mandates, it could have a material adverse effect on our results of operations.
24 Existing environmental laws or regulations may be revised and new laws or regulations seeking to protect the environment and natural resources may be adopted or become applicable to us. Areas in our service territories that are currently attainment areas under National Ambient Air Quality Standards could be designated as non-attainment areas due to new air monitoring results. These revised and new laws or regulations and any areas in our service territories designated as non-attainment may require regulation of mercury, nitrogen oxide, sulfur dioxide, carbon dioxide (CO2) and other greenhouse gases (GHG) emissions, particulates, coal ash and other coal combustion products, wastewater discharges, cooling water intake structures, and threatened, endangered or invasive species.

Actions related to global climate change and reducing GHG emissions could negatively impact us - The primary GHG emitted from our utility operations is CO2 from combustion of fossil fuels at our generating facilities, which are primarily coal-fired facilities. We could incur costs or other obligations to comply with any GHG regulations that are adopted in the future, and could become the target of legal claims or challenges, because generating electricity using fossil fuels emits CO2 and other GHGs. In 2013, a series of actions were announced to reduce carbon emissions, prepare the U.S. for the impacts of climate change, and lead international efforts to address global climate change. In November 2014, future targets for GHG emission reductions for the U.S. were announced in anticipation of achieving a global climate agreement.
The following are some proposed regulations that are expected to impact our operations. In January 2014, the EPA published proposed regulations governing GHG emissions from new generating facilities, which would impact IPL's Marshalltown Generating Station in Iowa and WPL's proposed Riverside Energy Center expansion in Wisconsin. In June 2014, the EPA issued its Clean Air Act Section 111(d) proposal to reduce CO2 emissions from existing fossil-fueled generating facilities. The EPA's proposal is based on broad measures to lower CO2 emissions, which could impact the dispatch of existing fossil-fueled generating facilities and the fuel mix used to generate electricity, and require other actions in order to achieve CO2 emission reduction goals. Due to the uncertainty of the final form of the GHG emissions regulations and solutions, including available control technologies, to comply with regulations to reduce GHG emissions, including CO2, we cannot provide any assurance regarding the potential impacts such future regulations would have on our operations.

Renewables - operating hydroelectric generators and current wind projects, as well as evaluating the development of future wind sites and solar projects. IPL and WPL currently have up to 400 MW and 200 MW of undeveloped wind sites, respectively, available for future wind projects. Alliant Energy, IPL and WPL are also exploring opportunities to integrate solar projects into the portfolio of energy resources as the cost to produce solar energy continues to decline.
Installing emission controls at the more efficient coal-fired EGUs, increasing levels of energy produced by natural gas-fired EGUs, and increasing levels of energy produced by wind projects and other renewable energy resources results in significant environmental benefits. As a result of these efforts, SO2 and NOx emissions are currently expected to be reduced by approximately 90% and 80%, respectively, from 2005 levels by 2025. Mercury emissions are currently expected to be reduced by approximately 90% from 2009 levels by 2025. CO2 emissions have been reduced by approximately 15% from 2005 levels.

CSAPR - CSAPR is a regional SO2 and NOx cap-and-trade program, where compliance with emission limits may be achieved by purchasing emission allowances and/or reducing emissions through changes in operations or the additions of emission controls. In 2015, CSAPR replaced CAIR. Compliance with CSAPR emissions limits began in 2015, with additional emissions limits reductions beginning in 2017. The emission allowances used for Acid Rain and CAIR program compliance cannot be used for compliance with CSAPR. CSAPR emission allowances may be banked for future year compliance. Alliant Energy, IPL and WPL will continue to monitor legal and regulatory developments related to CSAPR and currently expect to meet the final compliance requirements based on planned and completed emission controls projects for various EGUs.
CAVR - CAVR requires states to develop and implement plans to address visibility impairment in designated national parks and wilderness areas across the U.S. with a national goal of no impairment by 2064. These implementation plans require BART emission controls at certain IPL and WPL fossil-fueled EGUs that were built between 1962 and 1977 and other additional measures needed for reducing state contributions to regional haze.

GHG Emissions - Climate change continues to be assessed by policymakers including consideration of the appropriate actions to mitigate global warming. There is continued debate regarding the public policy response that the U.S. should adopt, involving both domestic actions and international efforts.
In 2009, the EPA issued a finding that GHG emissions contribute to climate change, and therefore, threaten public health and welfare. This enabled the EPA to issue rules to report and regulate GHG emissions under the authority of the CAA. The EPA Mandatory GHG Reporting rule requires sources above certain threshold levels to monitor and report emissions. The primary GHG emitted from Alliant Energy's, IPL's and WPL's utility operations is CO2 from the combustion of fossil fuels at their larger EGUs. Emissions of GHG are reported at the facility level in CO2e and include those facilities that emit 25,000 metric tons or more of CO2e annually. Annual emissions reported to the EPA for electric utility and natural gas distribution operations, in terms of total mass of CO2e, were as follows (in millions of metric tons):
Alliant Energy IPL WPL
2013 2012 2011 2013 2012 2011 2013 2012 2011
CO2e emissions (a) 26.6 25.2 26.7 10.9 10.8 12.1 15.7 14.4 14.6
(a) CO2e emissions reported to the EPA represent all emissions from the facilities operated by IPL and WPL and do not reflect their share of co-owned facilities operated by other companies. GHG Tailoring Rule - In 2010, the EPA issued the GHG Tailoring Rule, which establishes a GHG emissions threshold for major sources under the PSD construction permit and Title V operation permit. In June 2014, the Supreme Court ruled that the EPA may not treat GHG emissions as 'air pollutants' for determining whether a major source is required to obtain a PSD or Title V permit, but held that the EPA can continue requiring Best Available Control Technology for GHG emissions from sources otherwise subject to review under the PSD program. This rule remains subject to legal challenges and further rulemaking may also be required to update state regulations implementing the GHG Tailoring Rule to make the Supreme Court's decision effective.
Clean Air Act Section 111(d) - In June 2014, the EPA issued proposed standards under Section 111(d) of the CAA to reduce CO2 emissions from existing fossil-fueled EGUs. The EPA's proposal is based on broad measures that can reduce CO2 emissions from existing fossil-fueled EGUs, including making existing coal-fired EGUs more efficient, increasing dispatch of existing combined-cycle natural gas-fired EGUs, maintaining or expanding zero- or low-CO2 energy resources such as renewables and nuclear, and reducing customer demand for electricity through energy efficiency programs. The state-specific goals are based on an emissions rate basis measured in pounds per net MWh. The EPA is proposing a two-part goal structure: an 'interim goal' that each state meets an average threshold over the period from 2020 through 2029, and a 'final goal' based on a three-year rolling average that each state meets beginning in 2030.
State plans will determine the specific compliance requirements applicable to EGUs. Each state has flexibility in determining how to achieve the goals, which can include the broad measures included by the EPA as well as any other enforceable measures that the state can demonstrate will reduce CO2 emissions from existing fossil-fueled EGUs. The EPA also proposed to give states the option to convert the rate-based goal to a mass-based goal measured in tons. States can develop a state-only plan or collaborate in developing regional multi-state plans. State plans that provide details of how these guidelines are to be met would be required by June 30, 2016. If a state needs additional time and provides proper notification and explanation, the EPA's proposal allows for a one-year extension to submit state-only plans and a two-year extension if a state elects to join a regional multi-state program. In August 2014, the EPA's legal authority to issue the proposed standards under Section 111(d) of the CAA was challenged. The EPA is currently expected to issue final standards in 2015. Depending on the measures included in state plans for Iowa and Wisconsin, the expected dates for the retirement and fuel switching of certain of IPL's and WPL's coal-fired EGUs may be impacted by the new requirements. The implications of these new 52 requirements and the resolution of legal challenges remain highly uncertain, and as a result Alliant Energy, IPL and WPL are currently unable to predict with certainty the final outcome of these standards, but expect that expenditures to comply with any regulations to reduce GHG emissions could be significant.
Clean Air Act Section 111(b) - In January 2014, the EPA published revised proposed New Source Performance Standards under Section 111(b) of the CAA for GHG emissions, which would establish CO2 emissions limits for certain new fossil-fueled EGUs.

2014 vs. 2013 Summary - Electric production fuel expense increased $13 million in 2014 primarily due to the unseasonably cold weather conditions in Alliant Energy's service territory in the first quarter of 2014, which resulted in higher commodity prices and increased customer demand in the first quarter of 2014. This contributed to higher MISO dispatch of IPL's and WPL's EGUs in the first quarter of 2014. The increase in 2014 was also due to changes in the under-/over-collection of fuel-related costs at IPL. These items were partially offset by deferred fuel-related costs incurred that fell outside the approved bandwidth for 2014 at WPL, as well as lower dispatch at WPL's coal-fired EGUs during the third quarter of 2014, which included impacts of lower than planned coal deliveries.
Energy purchases expense increased $114 million in 2014 primarily due to increased prices for electricity, partially resulting from IPL's new DAEC PPA and the expiration of WPL's Kewaunee PPA, and increased volumes partially due to lower dispatch of WPL's coal-fired EGUs during the third quarter of 2014. The increase was also due to extremely cold temperatures in the first quarter of 2014 contributing to higher prices for electricity purchased by IPL and WPL from wholesale energy markets (primarily MISO) for 2014.

These increases were partially offset by the impact weather conditions had on electric sales in 2014. The unseasonably cold weather conditions in IPL's and WPL's service territories in the first quarter of 2014 increased sales and the cooler than normal summer temperatures during the third quarter of 2014 decreased sales. In comparison, temperatures during the third quarter of 2013 were warmer than normal resulting in increased sales. These changes in weather conditions caused an overall decrease in residential and commercial sales in 2014 compared to 2013. The 2013 increase was due to increases in weather-normalized retail sales volumes primarily at WPL related to economic recovery and modest customer growth experienced in WPL's service territory. These increases were partially offset by the unseasonably warm weather conditions during the third quarter of 2012 and a decrease in industrial sales volumes at IPL in 2013 due to lower co-generation customer requirements.
