A facility that converts high-voltage electrical power to usable levels for a job site or facility. Subcontractors in construction and oil & gas often work in, around, or on behalf of substations. Strict access controls and electrical safety certifications are typically required.
Substation
Related Terms
Modular Water Storage
IndustryPortable, stackable tank systems used on remote job sites to store potable, process, or wastewater. Subcontractors deploy them quickly without permanent infrastructure. Common on pipeline, camp, and frac support contracts.
Grid Interconnection
IndustryThe process of connecting a power generation asset to the public electrical grid. For subcontractors, it triggers specific commissioning milestones, inspections, and sign-offs. Delays in interconnection approval can directly impact project timelines and invoicing.
Physical Oil Price
IndustryThe actual market price paid for real barrels of oil delivered at a specific location, as opposed to futures contract prices. For subcontractors, client budgets and contract award activity closely track physical oil prices. When physical prices drop, project deferrals and rate pressure often follow quickly.
Reactivation
IndustryThe process of bringing a dormant well, pipeline, or piece of equipment back into active service, often requiring subcontractors to mobilise crews, conduct inspections, and complete compliance checks before full operations can resume. For field service companies, reactivation work can represent a significant surge in contract opportunities, particularly during periods of rising commodity prices.
VRU (Vapour Recovery Unit)
IndustryA compression system that captures hydrocarbon vapours from storage tanks or production equipment instead of venting them. Subcontractors are often hired to install, maintain, or service VRUs to meet emissions regulations. Familiarity with VRU work is increasingly required on oil and gas production sites.
Grid Hardening
IndustryUpgrades to electrical infrastructure that improve resilience against outages, extreme weather, and physical damage. For subcontractors, it drives demand for line work, equipment installation, and civil construction crews. Contracts often involve tight timelines and utility compliance requirements.
