Carbon Reductions and Climate Goals
Alliant Energy’s plans for a clean energy future are expected to exceed the carbon reductions and climate goals pledged originally by the U.S. under the voluntary United Nations Paris Accord.
The Paris Accord’s central aim is to strengthen the global response to the threat of climate change. This would be done by keeping a global temperature rise this century well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius.
U.S. Paris Accord Goal:
Reduce greenhouse gases 26-28% below 2005 levels by 2025
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. This includes 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.
Alliant Energy also is participating in an Electric Power Research Institute technical study assessing the state of the science for evaluating a company-specific climate policy scenario analysis or greenhouse gas goal. Key insights from the published study found that there is significant uncertainty between a global temperature goal and an individual company’s emission pathway. More robust methodologies are needed to support company-specific evaluations that consider uncertainties, including attainability of very low global emissions pathways, specific policy design features, non-climate-policy drivers and company-specific circumstances.
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*
*Based on approximate capacity in megawatts as of December 2019
**Does not include Wisconsin Clean Energy Blueprint solar of 1,000 MW to be in-service by end of 2023
**Retirement of 414 MW of coal by end of 2022
Our energy mix is changing as we continue our move to cleaner energy.
Planned resource additions*
Alliant Energy’s regulated utilities currently own 1,097 megawatts of wind, 43 megawatts of hydroelectric, and 6.2 megawatts of solar capacity. Planned new resource additions include 680 megawatts of owned wind by the end of 2020 as well as expanding our solar power resources. This will be complemented with flexible, highly efficient natural gas generation plus more than 1,000 megawatts of renewable purchase power agreements in 2020. 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.
*owned fossil-fuel generation
*owned fossil-fuel generation
We have 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
Alliant Energy’s water withdrawals have decreased due to retirement of fossil-fueled generating facilities. We are implementing water conservation measures and adding renewable resources to further reduce water use from our electric operations.
Integrated resource planning overview
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 and regulations to reduce greenhouse gas emissions or their monetized effects. Alliant Energy utilizes economic projections 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.
