Overview

Veresen was a Calgary-based Canadian energy infrastructure company that operated across the midstream natural-gas and power sectors. It developed from Fort Chicago Energy Partners L.P., a publicly traded energy infrastructure business, and adopted the Veresen name as it broadened its portfolio beyond its original pipeline focus. The company was listed on the Toronto Stock Exchange under the ticker VSN. Its principal infrastructure interests included long-distance natural-gas transportation, ethane gathering, natural-gas-liquids processing, storage development, and power generation. The best-known pipeline asset associated with Veresen was Alliance Pipeline, a roughly 3,000-kilometre system connecting natural-gas supplies in western Canada with markets in the United States Midwest. Veresen also held an interest in the Alberta Ethane Gathering System, a pipeline network serving petrochemical facilities in Alberta, and was associated with Aux Sable Liquid Products, a natural-gas-liquids processing operation near Chicago that separated products including methane, ethane, propane, and butane. The company also operated or invested in a varied power-generation portfolio. Its assets and businesses included cogeneration and district-energy facilities in Canada and the United States, the Brush II generating facility in Colorado, East Windsor cogeneration in Ontario, and waste-heat recovery stations connected with the Alliance pipeline system. These operations supplied electricity, steam, or district heating to industrial, commercial, and municipal customers. Veresen additionally pursued hydroelectric and other renewable-energy opportunities, particularly in British Columbia, through interests and acquisitions involving businesses such as Swift Power and Pristine Power. Several proposed developments reflected Veresen's effort to expand its infrastructure platform. These included the Alton Gas Storage project in Nova Scotia and the Jordan Cove Energy Project, a proposed liquefied-natural-gas export terminal at Coos Bay, Oregon. The company's renewable-energy strategy also included proposed run-of-river hydroelectric projects and biomass-related development. Some of these initiatives remained at the proposal or development stage rather than becoming operating assets. In 2010, Fort Chicago announced agreements involving Pristine Power and three British Columbia hydroelectric assets owned by ENMAX Power Corporation. These transactions supported the company's stated move toward renewable generation and diversified its exposure beyond conventional gas infrastructure. The business continued to combine regulated-like or contracted infrastructure characteristics with development and commodity-exposed activities. Pembina Pipeline agreed to acquire Veresen in 2017. The transaction was reported at approximately C$9.7 billion, including assumed debt and other transaction considerations as described in coverage of the deal. Following completion, Veresen ceased to operate as an independent publicly traded company and its assets were integrated into Pembina's infrastructure portfolio. Veresen is therefore a defunct corporate brand rather than an active standalone energy company.

History

Veresen was established in 2003 as part of the evolution of Fort Chicago Energy Partners, a Canadian energy-infrastructure business based in Calgary. Its early identity was closely associated with natural-gas transportation and related midstream infrastructure. The company became publicly traded on the Toronto Stock Exchange and developed a portfolio spanning Canada and the United States. A central holding was Alliance Pipeline, a long-distance natural-gas system of approximately 3,000 kilometres linking western Canadian production with consumers in the U.S. Midwest. Veresen also participated in the Alberta Ethane Gathering System, which transported ethane to petrochemical facilities operated by Nova Chemicals at Joffre and Dow Chemicals at Fort Saskatchewan. Through Aux Sable Liquid Products, the company was involved in processing natural-gas liquids near Chicago, producing products such as methane, ethane, propane, and butane. The business expanded into power generation and district energy. Its portfolio included cogeneration facilities in Charlottetown, Prince Edward Island; London, Ontario; Ripon, California; and San Gabriel, California. The London facility supplied both electricity and district heating, while East Windsor in Ontario provided heat to Ford's Windsor plant as well as electricity. Other assets included the Brush II generating facility in Colorado and waste-heat recovery stations operated through NRGreen Power and associated with pipeline pumping infrastructure in Saskatchewan. Beginning around 2010, Fort Chicago pursued a more explicit diversification strategy into renewable power, with particular attention to British Columbia. It acquired or sought interests in hydroelectric and biomass projects and agreed to purchase Pristine Power, a developer whose portfolio included proposed hydroelectric projects. It also agreed to acquire three British Columbia hydro assets from ENMAX Power Corporation. Swift Power, acquired by Fort Chicago, pursued run-of-river hydroelectric opportunities in the province. These initiatives reflected a strategy of combining established gas infrastructure with contracted or development-stage renewable generation. Veresen's development portfolio also included projects outside its operating assets. The Alton Gas Storage facility was proposed for Nova Scotia, while the Jordan Cove Energy Project involved a proposed liquefied-natural-gas export terminal at the Port of Coos Bay in Oregon. Such projects exposed the company to permitting, commercial, and market-development risks and were not equivalent to completed operating facilities. After adopting the Veresen identity, the company continued to operate as a diversified energy-infrastructure platform with pipeline, gas-processing, storage, and power interests. In 2017, Pembina Pipeline agreed to acquire the company for a reported total value of about C$9.7 billion. Completion of the transaction removed Veresen from the public market and transferred its businesses into Pembina. Veresen consequently became a historical brand and legal entity rather than an active standalone operator.
