Xcel Energy's Mercury Reduction Plans

Xcel Energy submitted its mercury reduction plans to the Minnesota Public Utilities Commission as required by the Mercury Emissions Reduction Act of 2006. These plans are  Xcel Energy’s plans for reducing mercury at the Sherburne County generating facility in Becker and the Allen S. King plant in Oak Park Heights.

If this proposal meets certain requirements, Xcel Energy is allowed to recover the costs of these upgrades through rate increases. These requirements are spelled out in Minn. Stat. §§ 216B.68 to 216B.688.

As part of the process to determine whether this proposal meets these requirements, the MPCA is required to verify that the mercury emissions-reduction project qualifies under Minn. Stat. § 216B.684, which asks the MPCA to:

  • evaluate the environmental and human health benefits of the proposed project;
  • assess the technical feasibility and cost-effectiveness of the mercury controls; and
  • advise the Public Utilities Commission on the appropriateness of the project.

The MPCA has completed its review of the plans, and found that the projects will likely achieve the Mercury Emission Reduction Act’s goal of reducing mercury emissions by 90% from these coal-fired power plants, and that there is significant public health benefits from the control of mercury.
