- The Clean Power Plan was a key element toward United States achievement of the Paris Accord climate goal.
- The stated central climate goal of the Paris Accord is “Holding the increase in global average temperature to well below 2 degrees Celsius above pre-industrial levels”.
U.S. Paris Accord Goal:
Reduce greenhouse gases 26-28% below 2005 levels by 2025
Clean Power Plan Goal:
Reduce CO2 32% below 2005 levels by 2030
Long-term carbon outlook
There are many perspectives on the impacts of climate change and the future path to decarbonization of the global energy system. Our strategy will continue to contemplate broader changes in the energy sector including:
- Two-way flow of energy using smaller and decentralized energy resources
- Broad adoption of electric end-use technologies including transportation
- Increased use of renewable energy and battery storage systems
- Leveraging data systems to build smart and efficient infrastructure
We also support research and development projects to better understand long-term carbon planning. Alliant Energy is participating in an Electric Power Research Institute technical study designed to serve as a public resource by providing a scientific foundation and insights specific to the electric sector on climate policy scenario analysis and greenhouse gas emissions goals. In addition, we fund projects to expand knowledge on our clean energy transition such as analyzing the impacts of emerging technologies, strategies for electric vehicles and customer electrification, and integration of distributed renewables and energy storage.
Clean energy transition
We are transitioning our energy to a cleaner mix and expanding cost-effective renewable resources. We’re also investing in our electric and gas distribution infrastructure, making it stronger, smarter and more adaptable to support evolving energy technologies.
Transitioning our energy resources*
Our energy mix is changing as we continue our move to cleaner energy.
Planned resource additions*
Alliant Energy’s regulated utilities currently own 623 megawatts of wind, 43 megawatts of hydroelectric, and 6.2 megawatts of solar capacity. Planned new resource additions include 1,150 megawatts of owned wind by 2021 as well as expanding our solar power resources. This will be complemented with flexible, highly efficient natural gas generation and approximately 1,000 megawatts of renewable purchase power agreements. Natural gas generation supports a reliable and balanced energy mix that enables the development of intermittent renewable energy.
Smart and dynamic energy grid
We’re optimizing our grid to enable the new two-way flow of energy and
Modernizing our energy infrastructure will make it more flexible to respond to our customers’ needs, improve adaptability to new technologies, plus enhance resiliency and reliability.
Alliant Energy has a long history of environmental stewardship focused on meeting customers’ energy needs in an economical, efficient and sustainable manner. We proactively consider future environmental compliance requirements and proposed regulations in our planning, decision-making, construction and ongoing operations activities.
Metrics and targets guide our future environmental plans. Adopting a long-term strategy prepares us to achieve environmental compliance requirements. It also provides flexibility to adjust our plans if needed.

By the end of 2018, we will have permanently retired approximately 30% of our fossil-fueled generation capacity since 2005. This includes over 1,000 megawatts of retired coal-fired generation. We operate air quality control systems to reduce emissions from our remaining coal-fired generation units.
*owned fossil-fuel generation
Our electric operations will need to withdraw less water as we expand renewable generation. We also expect to eliminate wet ash handling processes and close all of our coal ash ponds by the end of 2023.
Integrated resource planning process
We are focused on managing energy costs for customers while being environmentally responsible, including preparation for a carbon-constrained future. Our electric utility subsidiaries, Interstate Power and Light (IPL) and Wisconsin Power and Light (WPL), are market participants in the Midcontinent Independent System Operator, Inc. (MISO) Regional Transmission Organization. By participating in MISO’s wholesale electricity markets, we provide customers in our service territory with reliable and cost-effective power.
Through technical analysis, MISO establishes requirements for the long-term efficiency and reliability of the electrical system. Adequate generation supply, including a reserve margin, is a key component to planning a reliable electric network, and we are obligated to satisfy those supply requirements.
We use an integrated resource planning process to:
- Determine future energy and capacity needs under a variety of potential sensitivities and futures with varying economic and regulatory policy outlooks.
- Develop an action plan that will satisfy those needs safely, efficiently, and responsibly.
Integrated resource planning process
The integrated resource planning process uses models to evaluate how energy and capacity needs balance with supply. The future planning horizon typically covers 15 to 30 years. We use a year-by-year load forecast that includes both the energy required at the time of maximum consumption and the total amount of energy consumed over time. Energy supply alternatives are modeled using expected performance characteristics, operating and capital costs.
The sensitivity scenarios we consider include potential future policy mandates to reduce greenhouse gas emissions, such as the court-delayed Clean Power Plan or possible replacement regulation, or the effects of monetized greenhouse gas emissions. Alliant Energy has utilized economic projections from the Wood Mackenzie consulting service for fuel prices, market energy costs, capacity prices, and emissions costs including carbon pricing. We will continue to evaluate appropriate integrated resource planning inputs for carbon in the future.
Ultimately, integrated resource planning results are further assessed in light of our strategy and non-quantifiable risks that cannot be considered in the model. This guides our decisions on the best future energy resources to meet our customers’ electricity needs.

Strategic plan opportunities
Our strategic plan aims to expand the portfolio of cleaner and renewable resources while accelerating energy growth to help minimize individual customer prices. We are also modernizing the power grid and gas distribution system to enhance safety, reliability and be more price-competitive and market-responsive for customers.
Alliant Energy expects to invest over $10 billion in these opportunities through 2026 to implement our strategic plan. Near-term capital expenditures from 2018 through 2021 focus primarily on adding renewables and distribution improvements.
Our energy efficiency programs help customers reduce their energy usage and related costs. As our energy portfolio becomes less carbon-intensive, we are also working to increase business adoption of electric forklifts, electric truck refrigeration units, and electric cars and trucks. Through electrification, we believe that electricity can enable broader economy-wide carbon reductions. Our recent activities to advance these initiatives are described in this online sustainability report.
We evaluate and report on potential risk factors, including risks that may be climate-related or carbon-related, in our company’s annual Form 10-K report to the U.S. Securities and Exchange Commission. Risks that may be associated with climate or carbon concerns can be physical risks associated with extreme weather events, regulatory risks associated with changing regulatory requirements and rate recoveries, and economic risks associated with additional required capital expenditures.
We have an enterprise risk management program to identify, communicate and manage significant risks in a structured framework. The risk assessment identifies key themes and trends, quantifies our key risks, and develops management plans and strategies. The Board of Directors is responsible for managing our overall risk profile. The Audit Committee oversees our risk assessment and risk management policies, our financial risk exposures, and how we monitor and control such exposures. The Operations Committee reviews and assesses operational risks including risks associated with climate or carbon concerns.
Programs, plans and actions are put in place to respond to risks that may be associated with climate or carbon concerns.
