Boswell Substation

Minnesota Power needed to construct the Boswell substation as an essential step towards delivering increased quantities of renewable and cleaner energy to the neighboring regions. This project played a crucial role in the comprehensive transformation of a coal plant, which was undergoing a significant upgrade to transition to a more sustainable and environmentally friendly energy source.

On the surface, the Boswell substation seemed to be a straightforward project. However, difficult subsurface conditions required the drilled shafts to be installed using slurry and a tremie. While the project offered many challenges, J.H. Hassinger was able to successfully complete the project to help Minnesota Power further foster a cleaner future and align with evolving energy standards.
