With an announcement in late 2023 by Dow Chemical that it would be undertaking an enormous expansion of its ethylene production site in Fort Saskatchewan, AB, it was immediately clear that Alberta’s ethane supplies would need to increase by a significant 110 Mb/d. As we’ll discuss in today’s RBN blog, a deal was signed in February between Dow and Pembina Pipeline Corp. that calls for the midstreamer to provide up to 50 Mb/d of additional ethane supplies and, according to executives at Pembina’s investor day earlier this month, will require the company to invest between C$300 million (US$220 million) and C$500 million (US$367 million) to build out its existing NGL/ethane infrastructure.
