This story is the second installment of a monthly series to update you on our crew’s progress in building two new Detroit substations: Promenade and Islandview. View the first installment here. 

At both sites, crews are digging out soil that is contaminated and unsuitable to build on. At Promenade, excavator operators are also removing an existing sanitary sewer system from the site. Representatives from The Research Corporation of New England (TRC) are regularly present at both sites to conduct tests for water and soil contamination. In the near future, DTE will fill the sites back up with MDOT Class II sand and compact to specifications for foundations and construction.    

As energy use evolves over time, these new substations will improve service for the community by providing additional power capacity and reducing the likelihood of power outages.
