"The new state-of-the-art technology at Boswell 4 will make the
generating unit among the cleanest and most efficient in the nation
while helping to preserve the reliable and affordable power our
customers expect," said
EnergyForward is the company's resource strategy to diversify its power supply to a balanced energy mix of one-third coal, one-third renewable energy and one-third natural gas. Minnesota Power's renewable energy portfolio has already enabled the company to meet the state of Minnesota's renewable energy standard of 25 percent by 2025 a decade early.
"Baseload coal generation remains an important energy supply component
supporting Minnesota Power's mission to deliver safe, reliable and
affordable electricity to its customers, even as we add more renewable

That investment also included the installation of a high efficiency
steam turbine at Boswell 4 resulting in 60 megawatts of increased power
capacity with no additional emissions. In
The Boswell 4 environmental upgrade involved replacing the existing wet scrubber and particulate control technology with a semi-dry system that uses less water, installing a powdered activated carbon injection system to capture flue gas mercury, and adding a fabric filter to further control particulates. A new 25,000-square-foot building houses a nine-module Alstom NID system that removes mercury, sulfur dioxide and particulates. Ash management entails the transport and storage of ash in a state approved ash cell that complies with applicable rules. The project meets the requirements of Minnesota's Mercury Emissions Reduction Act and the federal MATS rule (Mercury and Air Toxics Standards).
