Nicholas M. Gretener


Upstream, Midstream and Downstream Oil & Gas Regulatory and Commercial Lawyer at Bennett Jones Calgary

T: 403.298.3405

Nicholas Gretener's practice is directed towards the regulatory and commercial aspects of operations along the full energy chain—from Upstream (production - generation) to Midstream (processing - transmission) to Downstream (distribution - consumption).

Nick acts for oil and gas exploration, production and marketing companies, LNG producers, oil and gas transmission pipelines and shippers, local distribution companies and other energy producers and consumers.

He appears in hearings before regulatory tribunals across the country (such as the National Energy Board, the Alberta Utilities Commission, the British Columbia Utilities Commission and the Manitoba Public Utilities Board) on a wide array of energy issues, including rate and policy matters, facility certifications and energy export authorizations. Nick also negotiates and drafts energy contracts, particularly natural gas purchase/sale agreements, pipeline transportation agreements and oil and gas transportation tariffs for major Canadian pipelines. Nick has also worked on a number of pipeline project financings.

Prior to entering legal practice, Nick worked as a petroleum reservoir engineer for Gulf Canada Resources (now Conoco-Phillips) and draws on this background in providing effective representation on technical energy issues. He offers his clients practical advice on how to advance their projects through the regulatory process in a timely manner.
