Large solar power installations, typically 1 MW or greater, built to feed electricity directly into the grid. For subcontractors, these projects involve civil, electrical, and mechanical scopes across remote, fast-paced sites. Crews should expect high headcounts, strict commissioning timelines, and phased work packages.
Utility-Scale Solar
Related Terms
Lean Construction
IndustryA project delivery approach that eliminates wasted time, materials, and labour on job sites. Subcontractors use lean methods to tighten scheduling, reduce idle crew time, and improve handoffs between trades. It often involves short-interval planning tools like the Last Planner System.
Dispatchable Power
IndustryPower generation that can be turned on or off on demand, unlike solar or wind. For field crews, this means reliable site power for tools, lighting, and equipment regardless of weather. Generators and diesel units are common dispatchable power sources on remote job sites.
Curtailment
IndustryA reduction or suspension of oil, gas, or construction operations ordered by the operator or regulator. For subcontractors, curtailment often means standby, demobilisation, or reduced scope with little notice. Review your contract carefully for curtailment clauses that affect payment and mobilisation costs.
Pipeline Interconnect
IndustryA tie-in point where two or more pipelines are joined to allow fluid or gas transfer between systems. Subcontractors are often mobilised for the hot-tap, welding, and pressure-testing work at these connections. Scope can expand quickly, so confirm tie-in specifications before pricing the job.
Well Pairs
IndustryTwo horizontal wells drilled together — one injector, one producer — used in SAGD (Steam-Assisted Gravity Drainage) operations. Subcontractors often mobilise crews and equipment to service both wells simultaneously. Expect back-to-back work scopes and coordinated scheduling across a shared pad site.
Transmission Infrastructure
IndustryLarge-scale pipelines, compressor stations, and related facilities that move oil, gas, or power across long distances. Subcontractors are frequently mobilised for construction, inspection, and maintenance work on these assets. Scopes can be extensive, requiring multi-trade crews and strict regulatory compliance.
