TGG analyzes conventional, unconventional and renewable energy supply, as well its energy transportation. From mega-hydro projects in the 1980s to large crude oil pipelines of the 21st century, we work on the most challenging, complex and controversial energy projects in North America. For the last decade, TGG has focused on fossil fuel supply (shale oil and gas, Canadian tar sands and coal) and transportation (pipelines, rail and terminals).
