About FORTIS

FORTIS Inc. Like UNS Energy, Fortis was established as the publicly traded corporate parent of a local utility – Newfoundland Power – that has provided electric service since the late 1800s. As the company has expanded through a series of acquisitions, it has retained its commitment to disciplined, patient growth through continued focus on operational excellence.  Today, Fortis is the largest investor-owned gas and electric utility in Canada, providing gas and electric service to more than 3 million customers. Its regulated holdings include gas and electric utilities in five Canadian provinces, New York and two Caribbean countries.

ESG / Sustainability Performance

UNS Energy has worked with the Edison Electric Institute, the American Gas Association, investors and other member utilities to develop reporting metrics that allow investors to assess environmental, social, and governance (ESG) risks for each reporting utility.
