The Alberta-based utility company provides electric, gas, and infrastructure solutions. Its main subsidiary is Canadian utilities, which manages electricity, natural gas, and logistics. The main segments are power (production, transmission, and distribution), gas pipelines and liquid, Neltume Ports infrastructure, and logistics. It is based in Calgary, Alberta, and it has operations across Canada and Australia, the US, Mexico, and the United Kingdom. Canadian Utilities introduced a major undertaking called Atcoenergy, which offers efficient and sustainable energy services for Alberta. ATCO was founded in 1947, formerly known as Alberta Trailer Hire. It started with revenues of C$ 1,077 and 15 utility trailers, but now it is a multi-billion-dollar company. It is actively exploring the Canadian oil industry. In 1980, it acquired a 58.1 per cent stake of Canadian Utilities Limited from the US-based International Utilities regained its Canadian proprietorship. This crucial purchase was a turning point for the firm as it pioneered a sustainable top line to ATCO’s book and paid off its long-term investment. The company entered the emission-free or renewable energy business in 2003, with its 32-Megawatt, Oldman River hydroelectric producing plant. Currently, it has been jointly operating in collaboration with the Piikani Nation in southern Alberta. It expanded its footprints to Australia with its acquisition of WA Gas Networks in a C$ 1.1 billion deal in 2011. Now, it is the largest gas utility firm in Western Australia. In 2019, the company took a strategic step to sell its Canada-based fossil fuel-based production facilities for capital worth C$ 821 million to invest in advanced power generation operations.
