Investing in the Communities We Serve

At Alliant Power, we believe in being responsible stewards in the communities where we live and work. This social responsibility fuels our commitment to giving back in four key areas:

  • Ethics— We will always conduct business with integrity and respect. Alliant Power promotes safety, respect for our employees, customers and suppliers. We work diligently to honor our internal policies, respect the law and maintain transparency and collaboration in our partnerships.
  • Environment— Alliant Power recognizes the need to protect the natural environment. We will follow best practices for recycling, conserving energy, using environmentally friendly technologies and products, and donating to organizations that work to protect our resources.
  • Philanthropy— We are committed to donating a portion of our net income to support non-profit organizations whose mission is to care for children, support veterans, and encourage athletics in our communities.
  • Volunteering— Alliant Power encourages our employees to volunteer. Volunteering can be done through company-organized programs or individual efforts. This has taken the form of serving meals at the local Ronald McDonald House or biking to raise money for healthy meals for those in need.
