Donnelly Mechanical is Now an EQUANS Company

EQUANS is a leader in MEP and Facility Management in North America

In August of 2018, Donnelly Mechanical was acquired by ENGIE, a global energy and services group. The acquisition provided us access to a wide range of new resources including a much larger capital base. These resources have allowed us to offer a broader level of service beyond the typical scope of work including project funding and energy management solutions.

In July of 2021, ENGIE announced the launch of a new global business line called EQUANS.

EQUANS companies are leaders in mechanical and electrical construction, industrial and energy infrastructure, and building services across North America. The entities that make up EQUANS North America include a collaborative group of commercial infrastructure experts that support clients to optimize their energy use and efficiently run their facilities. With offices across the U.S. and Canada, our organization offers a rare combination of wide territorial reach and proven local expertise.
