Factory Expansion Electrical Scope Checklist in Fiji
Avoid Costly Delays in Your Factory Expansion
Expanding a factory in Fiji is exciting, but it can also feel risky. You want new lines running before the next peak season, and you need the power to be ready long before production ramps up. At the same time, you cannot afford long shutdowns or surprise faults once the new gear is in place.
Electrical work is often where factory projects slow down. Different designers, installers, and testers each look after their own piece, and gaps appear between the scopes. Cables do not match breakers, panels arrive undersized, or shutdowns have to be repeated because one system was missed. Every extra shutdown can mean lost output and extra stress for your team.
A turnkey electrical contractor takes a different approach. One partner looks after load studies, design, procurement, installation, testing and commissioning from the first idea through to energisation. That means fewer surprises, cleaner handovers, and better support when something needs to be adjusted quickly.
This checklist is written for project owners, facility managers and consultants in Fiji who want to brief contractors clearly, de-risk expansions and keep plants running safely and profitably while power systems grow.
Defining the Electrical Scope for Your Expansion
Before anyone starts drawing single-line diagrams, you need a clear link between the business plan and the electrical brief. Start by listing what is changing in the factory, not just in terms of equipment, but also in how you plan to run it.
It helps to cover questions like:
What new machines, process lines or buildings are you adding?
Will shifts increase or change, especially around export or tourism peaks?
Are you planning future stages that might double certain loads later?
Which areas must never lose power, such as cold rooms or servers?
Next, you and your electrical contractor should map the existing setup. This is where many projects skip steps and later run into trouble. A good map will include:
Incoming utility supply and metering
Main switchboard ratings and spare capacity
Distribution boards and motor control centres
Earthing systems and bonding points
Critical circuits like chillers, compressors and IT racks
From that information, your contractor can prepare clear deliverables you can use for internal approvals and planning. At a minimum, ask for:
Updated and proposed single-line diagrams
Load schedules for existing and new equipment
Cable routing concepts so clashes with process services are avoided
A preliminary bill of quantities to support budgeting and procurement plans
With a scope like this, you can have better talks with your internal team before any gear is ordered.
Load Studies and Switchboard Upgrade Strategy
Load studies are the quiet hero of any successful expansion. When they are done early and done well, they stop a long list of problems. When they are rushed, you often see tripping, overheating and unplanned shutdowns later.
A detailed load study from a turnkey electrical contractor should cover:
Expected running loads and starting currents for motors
Diversity factors for different production areas
Power factor and how it might change with the new equipment
Harmonics from variable speed drives and modern production lines
From here, your contractor checks if the existing main switchboards, transformers and feeders can safely carry the extra demand. In warm, humid conditions like we see year-round in Fiji, derating can be a real issue, especially in crowded electrical rooms with limited ventilation.
If capacity is tight, you have a few options:
Replace or extend the main switchboard
Split critical loads to their own sections or boards
Add extra distribution boards closer to large new loads
Plan staged upgrades to match production windows and reduce shutdown time
Safety and compliance cannot be an afterthought. Make sure your electrical partner also looks at:
Fault level calculations for new and existing equipment
Protection coordination so the right breaker trips first
Arc flash risk checks and suitable labelling
Clear and permanent labelling to suit local standards and insurance needs
When this work is done as part of one integrated package, future maintenance and modifications are much easier.
Utility Coordination and Regulatory Approvals
No factory expansion can be energised without the utility on board. In Fiji, that means engaging with Energy Fiji Limited and any other authorities early, not at the end of the project when everyone is in a rush to turn the power on.
A turnkey electrical contractor can handle most of this interaction for you. Typical tasks include:
Preparing updated single-line diagrams and maximum demand estimates
Proposing protection settings at the point of supply
Submitting technical data sheets for major switchgear and transformers
Clarifying any need for metering changes or tariff discussions
Industrial sites often also face bigger questions around:
Transformer upgrades or replacements
New or extended substations
Interfaces between generators, automatic transfer systems and the grid
Access and safety requirements for inspection and switching
An experienced contractor that understands local expectations helps avoid resubmissions, missing documents and last-minute variations. That reduces the chance of your project slipping past the planned expansion window while everyone waits for approval.
Shutdown Planning, Installation, Testing and Commissioning
Even the best design can cause trouble if the shutdown plan is weak. Production teams need to know exactly what will be off, for how long, and what protection will stay in place for critical areas like cold storage, compressors and IT rooms.
Good shutdown planning usually includes:
Choosing off-peak periods, night works or weekends where possible
Detailed method statements and risk assessments
Temporary power or backup plans for key loads
Clear communication with operations, maintenance and safety teams
During installation, quality matters as much as speed. In Fiji’s humid and coastal conditions, attention to detail can make the difference between a long-life system and one that fails early.
Correct cable sizing and neat routing in trays or conduits
Proper glands and terminations to keep out moisture and dust
Strong, tested earthing and bonding connections
Clear and durable labels that match the drawings and schedules
Once gear is installed, testing and commissioning brings it all together. A full process should include:
Insulation resistance and continuity tests for new cabling
Functional testing of breakers, relays and control circuits
Checks that protection operates as designed
Integration tests with automation or process control systems
Final as-built drawings, test records and basic training for your on-site team
When the same contractor has been involved from the beginning, these last steps are quicker and cleaner, with fewer surprises.
Partnering With a Turnkey Electrical Expert in Fiji
Factory expansions work best when the electrical scope is treated as one connected system instead of separate pieces. From early load studies and switchboard planning to utility liaison, shutdown execution and commissioning, having a turnkey electrical contractor responsible for the full picture reduces risk, cuts down on rework and protects production time.
For industrial, commercial and institutional projects across Fiji, our team at Sonic Electric Supplies focuses on that full-scope approach. We are a licensed electrical contractor, and we work with clients who want clear designs, practical installation plans and reliable support through to energisation and beyond. When you review your future expansion plans, it helps to gather your existing electrical data, think through your production peaks and engage an experienced partner early so the electrical scope and programme support your wider business goals.
