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.
BESS (Battery Energy Storage System)

Sand Management
IndustryThe process of controlling, monitoring, and removing sand produced alongside oil and gas to protect wellbore equipment and surface facilities. Subcontractors may be hired to install sand screens, separators, or erosion monitoring systems. Poor sand management accelerates equipment wear and increases maintenance callouts.
Solar-Plus-Storage
IndustryA power system pairing solar panels with on-site batteries to supply electricity at remote job sites. Subcontractors may install, maintain, or work alongside these systems instead of diesel generators. Familiarity with this equipment is increasingly expected on off-grid oil and gas and construction sites.
Grid Congestion
IndustryGrid congestion occurs when electrical transmission lines carry more power than they can handle, causing bottlenecks. For subcontractors, it can delay grid-tied project energisation and push back commissioning milestones. Remote site work may shift to temporary generation until congestion is resolved.
Pjm (pennsylvania-New Jersey-Maryland) Interconnection Queue
IndustryA waiting list managed by PJM for new power generation and transmission projects seeking grid connection approval. Subcontractors use it to track upcoming infrastructure builds and time their bids accordingly. Long queue backlogs signal sustained field work demand in the PJM service territory.
Balance-Of-Plant
IndustryAll supporting systems and infrastructure outside the primary process equipment, such as electrical, piping, HVAC, and civil works. For subcontractors, BOP (Balance-of-Plant) scope often represents the bulk of awarded field labour. Knowing what falls under BOP helps avoid scope gaps and missed bid items.
Metallographic Replication
IndustryA non-destructive field technique used to examine the microstructure of in-service metal components without removing them. Technicians apply a softened acetate film to a polished surface, then analyse the hardened impression under a microscope. Subcontractors use it to assess weld integrity, creep damage, or material degradation on piping and pressure vessels.
