Industry Glossary Term

Building Electrification

The process of replacing fossil fuel-based systems in buildings with electric alternatives, such as heat pumps and induction equipment. For subcontractors, it drives demand for electrical, HVAC, and mechanical retrofits. Crews must often hold updated certifications to work on high-voltage systems and EV (Electric Vehicle) charging infrastructure.

Related Terms

Shale Basin

Industry

A large geographic region containing shale rock formations targeted for oil and gas extraction through horizontal drilling and hydraulic fracturing. For subcontractors, shale basins like the Montney or Duvernay represent high-volume, multi-year work corridors. Expect cyclical demand, remote mobilisation, and repeat frac and completions contracts.

BESS (Battery Energy Storage System)

Industry

A large-scale battery installation that stores and dispatches electrical power on remote or off-grid job sites. Subcontractors may be hired to install, commission, or maintain these units alongside diesel generators or solar arrays. Familiarity with high-voltage systems and OEM safety protocols is typically required.

Spoil Pile

Industry

Excavated soil, rock, or debris removed during trenching or grading and stockpiled on-site. Subcontractors are often responsible for its placement, management, and disposal per site plans. Improper handling can trigger environmental compliance issues and project delays.

Dual-Fuel System

Industry

An engine or generator that runs on two fuel sources, typically diesel and natural gas, allowing switching based on availability or cost. Common on remote job sites where field crews manage fuel supply logistics. Subcontractors may need certified technicians and specific maintenance protocols to operate this equipment.

Support Activities for Oil and Gas Operations

Industry

An industry classification covering subcontractors who provide services to upstream oil and gas producers without extracting resources themselves. This includes well servicing, site prep, equipment rental, and pipeline support. Most field service companies in oil and gas fall under this category for tax and regulatory purposes.

Transmission Line

Industry

A high-voltage power line that moves electricity over long distances between generation sources and distribution networks. Subcontractors often support transmission line projects through clearing, trenching, tower erection, and right-of-way maintenance work.
