Planning for a sustainable future
Our Wisconsin Clean Energy Blueprint includes plans to provide enough solar energy to power about 260,000 Wisconsin homes by the end of 2023. This will total up to 1,000 megawatts of solar that builds upon the 1,000 megawatts of wind that we’re completing in Iowa by the end of 2020.
We are continuing to engage with our stakeholders on relevant topics such as customer renewable energy options, energy efficiency programs, electrification, infrastructure and technology needed to modernize the way we provide power. These touchpoints will enable our company to deliver the energy solutions and exceptional service essential for achieving a sustainable future in the communities we have the privilege to serve. We are working on our Iowa Clean Energy Blueprint in 2020 and plan to finish by the end of the year.
We’re accelerating our clean energy vision and goals.
Iowa wind farms boost local communities
By the end of 2020, we will have invested $2 billion in new wind farms located in Iowa. This includes eight wind farms that went into service from 2009 to 2020. We have the capacity to deliver about 1,450 megawatts of clean energy.
This expansion of wind energy also delivers strong economic benefits to local communities. Participating counties, communities and schools will receive an estimate of up to $730 million in property taxes over 40 years. Landowners will receive approximately $342 million in lease payments over the same time.
Alliant Energy’s owned wind generation by end of 2020:
Battery provides storage, benefits grid
We energized a battery in Wellman, Iowa, in December 2019 to more sustainably meet our customer’s energy needs. The project not only avoids rebuilding a portion of the local energy grid – it also has expanded the amount of solar power that can be used on the system. Operating the battery as a buffer will level out power fluctuations caused by changes in the sun’s intensity. This new technology also optimizes charging times, reducing costs and provides backup power from the grid improving both energy affordability and reliability for all customers.
Solar and battery pilot project saves dollars
Finding creative energy solutions for a customer was central to a project that was energized in January 2020: bringing power to a remote building near Sauk City, Wisconsin. The building is owned by the Wisconsin Department of Natural Resources. The power line running to it needed to be rebuilt. The cost: $400,000. Our project team found that a combination of solar panels and battery storage could do the same thing. The cost: less than $200,000. Plus, we added a renewable energy option. Win-win!
We’re electrifying to reduce emissions
An electric vehicle is more efficient and already offers a 50% reduction in carbon dioxide emissions by using power from clean energy resources expanding on the Midwest energy grid. Providing emissions-free work site conditions significantly benefits employees by improving local air quality and reducing noise levels. Our company is taking advantage by electrifying our own operations.
