The acquisition of Integrys Energy by Wisconsin Energy is one step closer to being finalized.
The Public Service Commission of Wisconsin has given formal written approval of the acquisition.
The companies announced the proposed acquisition in June of 2014.
All required federal approvals have been received, and shareholders for both companies approved the transaction in November 2014.
With the approval by the Public Service Commission of Wisconsin and the Michigan Public Service Commission last month, only Illinois and Minnesota state approvals remain outstanding.
If all regulatory approvals are received, close of the transaction is anticipated by the end of the summer.
