Related Terms
T&D (Transmission and Distribution)
IndustryThe network of high-voltage power lines, towers, substations, and local distribution lines that move electricity from generators to end users. Subcontractors in this sector handle tasks like line construction, pole installation, and substation work. T&D projects are often awarded through utility frameworks or provincial grid operators.
STEO (Short-term Energy Outlook)
IndustryA monthly U.S. Energy Information Administration report forecasting near-term oil, gas, and energy prices. Subcontractors use it to anticipate upstream spending trends and project demand for field services. Shifts in STEO forecasts often signal whether operators will ramp up or cut back work programmes.
CAPEX (Capital Expenditure)
IndustryFunds an operator spends on major assets like wells, pipelines, or facilities. High CAPEX cycles mean more subcontract opportunities for field crews and equipment providers. Low CAPEX periods often signal slower work volumes and tighter bid competition.
Turnaround
IndustryA planned shutdown of a facility for maintenance, inspection, and repair. Turnarounds often require large numbers of contractors and subcontractors working intensive schedules.
IEA (International Energy Agency)
IndustryAn intergovernmental organisation that publishes global energy outlooks and demand forecasts, which subcontractors and field service companies use to anticipate shifts in upstream and downstream activity levels that may affect project pipelines and contract opportunities.
Working Interest
IndustryAn ownership stake in an oil and gas lease that obligates the holder to pay a share of exploration and production costs. For subcontractors, knowing who holds working interest helps identify who is ultimately responsible for approving work orders and invoices. Operators typically hold majority working interest and are your primary point of contract.
