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.

Related Terms
EIA (Energy Information Administration)
IndustryA U.S. federal agency that publishes energy data, forecasts, and market reports. Subcontractors use EIA reports to track oil and gas price trends and anticipate shifts in project demand. Monitoring EIA data helps field service companies time bids and resource planning.
Retrofit
IndustryUpgrading or modifying existing equipment to meet new specs, safety standards, or operational requirements. Subcontractors are often hired specifically for retrofit scopes on aging infrastructure. Work may require specialised certifications and careful coordination with the client's existing systems.
Surface Milling
IndustryA machining process that removes material from a flat surface to restore or achieve precise tolerances on equipment components. Subcontractors are often mobilised to perform surface milling on wellheads, flanges, or structural steel on-site. Proper equipment certifications and dimensional records are typically required for handover documentation.
Marine Infrastructure
IndustryOffshore and coastal structures such as platforms, jetties, pipelines, and subsea systems where field work is performed. Subcontractors must hold marine-specific certifications and follow offshore safety protocols. Mobilisation costs and logistics are typically higher than onshore projects.
Interconnection
IndustryThe physical linking of two or more systems, pipelines, or electrical networks at a shared tie-in point. For subcontractors, interconnection work often requires strict coordination with the prime contractor and operator. Scope boundaries and handoff responsibilities must be clearly defined in your subcontract.
Sitework
IndustryPreparatory ground-level work completed before main construction begins, including grading, excavation, and utility rough-ins. Subcontractors are often scoped for sitework as a standalone package. Delays in sitework directly impact downstream trade access and schedule.
