Indiana regulators approved a plan for Indianapolis Power & Light Co. to invest $511 million in pollution controls at its Petersburg and Harding Street coal-fired power plants. The controls are expected to reduce mercury emissions by 80 percent at both plants.
IPL picked Indiana Environmental Partners (IEP) for engineering, procurement and construction of the controls. Major construction at the Petersburg plant is set to begin this fall.
IPL filed a request with the Indiana Utility Regulatory Commission to invest $631 million into a proposed 650 MW combined-cycle natural gas-fired power plant near Martinsville.
