Fortis Inc. operates as a diversified leader in the North American regulated utility industry, with its business heavily weighted toward electricity transmission and distribution. The company's key subsidiaries include ITC Holdings, an independent high-voltage transmission utility in the U.S., alongside regional operators such as UNS Energy in Arizona, Central Hudson in New York, and FortisBC and FortisAlberta in Canada. Geographically, the United States is the largest earnings contributor, though the company maintains a substantial footprint across five Canadian provinces and the Caribbean. Fortis manages over 91,000 circuit kilometers of electricity distribution lines and 51,700 kilometers of natural gas pipelines. Its business model relies on government-approved regulated rates, which provide predictable cash flows and support its capital investment programs.
