The steel industry has a massive carbon footprint, as much as 6% to 7% of the world's greenhouse gas emissions, according to a Rocky Mountain Institute study. A new Nucor steel microplant in Missouri is trying to put a dent in that number.

Nucor's micromill in Sedalia, Missouri, is set to be the first U.S. steel plant to run on wind energy, according to Evergy. The $250 million plant, which is expected to open by the end of the year, is a partnership between the steel company and local utility Evergy, which will power the plant after a 75 megawatt power purchase agreement between the companies.

With sustainability goals becoming increasingly important to companies, plants like this one could be built more frequently, and Evergy senior vice president Chuck Caisley says that the Midwest is in a prime position for more projects like the Nucor plant.

"We sit in the Saudi Arabia of wind," Caisley said. "I think that increasingly there will be sustainability requirements companies will want to meet. In Kansas and midwest Missouri we have great wind to meet current and prospective customers with price competitiveness and sustainability. It reduces our environmental footprint in the area and creates jobs."

The Nucor plant was not initially conceived with a goal of using wind energy, but the Evergy executive said a competitive price ended up attracting the steel-producing company to Missouri over other wind-rich states, like Nebraska and Kansas, who were finalists for the project. Caisley said that the price competitiveness, along with helping Nucor meet sustainability goals, were important to get the project to Missouri. There is a law in the state that lets utilities apply for discounted electric rates for aluminum and steel producers that buy significant amounts of energy.

In an email, Nucor said they are constantly looking for ways to increase their energy efficiency to decrease their environmental impact and that they are pleased that their power provider in Missouri is developing wind resources that can be part of the electric grid serving their new rebar micromill.
