Bahamas Clean Energy Transition Project

1. Project Background: Severe Challenges in the Bahamas’ Energy Transformation

The Bahamas, a tropical island nation, has long relied on expensive, high-emission diesel generation, leading to unstable power supplies, frequent outages, and exorbitant electricity costs—especially across its Family Islands. Between 2023 and 2024, the government launched a landmark Clean Energy Transition & Natural Gas Replacement Program, partnering with local energy authorities to replace aging diesel plants with a modern 177MW LNG facility, upgrade the national power grid, and boost renewable energy integration.

Our client, a leading EPC contractor on this national project, faced critical cable supply hurdles:

Harsh Environmental Stress: The coastal, high-humidity, salt-spray air and frequent hurricane conditions demanded cables with exceptional corrosion resistance, UV stability, and weather durability. Standard cables degraded rapidly, causing frequent breakdowns.

Stringent Certification Mandates: All wiring required strict UL safety certifications (UL 44, UL 83, UL 4703) to meet U.S./NEC codes and local Bahamian electrical standards.

Reliability & Longevity: The grid demanded 99.9% uptime. Cables needed to withstand extreme heat (up to 90°C) and persistent moisture without performance loss.

Logistics & Speed: Remote island locations required fast, reliable delivery; delays would stall the entire $130M grid upgrade.

Prior Bad Experiences: The client had received non-compliant, low-durability cables from other suppliers, leading to reworks, budget overruns, and missed deadlines.

They needed a partner with proven island energy project experience, full UL certification, and cables engineered for tropical, high-salt environments.

2. Our Tailored Cabling Solution: Product Selection & Core Advantages

We conducted an on-site environmental and engineering assessment, then recommended a high-performance, UL-listed cable package optimized for the LNG plant, grid backbone, and distribution networks. Our solution centered on USE-2, THWN-2, THHN, and XHHW-2 cable for electrical systems, each chosen to solve specific pain points.

Key Cable Products Supplied (with Sizes & Specifications)

USE-2 (Underground Service Entrance)

Sizes: 250kcmil, 4/0 AWG, 2/0 AWG (copper conductor, XLPE insulation)

Application: Direct-buried main feeder lines connecting the LNG power station to substations; outdoor overhead lines

Why USE-2?

UL 44 listed, sunlight-resistant, salt-moisture-proof, and rated 90°C for both wet/dry conditions. Superior to standard USE cables: thicker XLPE insulation blocks saltwater corrosion, enabling 30+ year service life without replacement.

THWN-2 (Thermoplastic Heat and Water Resistant Nylon-Coated)

Sizes: 14 AWG – 500kcmil

Application: Indoor control rooms, switchgear, distribution panels, and wet-location wiring at LNG facilities

Why THWN-2?

UL 83 certified, 90°C wet/dry rating, oil/gas/chemical-resistant, and nylon-jacketed for extra abrasion protection. Outperforms THWN (75°C) in high-temperature LNG plant environments, preventing insulation breakdown.

THHN (Thermoplastic High Heat-Resistant Nylon-Coated)

Sizes: 12 AWG – 300kcmil

Application: Dry indoor power and control circuits, lighting, and auxiliary systems

Why THHN?

Cost-effective, UL 83 listed, 90°C dry heat resistance, and flexible for tight panel routing. Reliable for non-exposed, dry sections of the plant.

XHHW-2 cable for electrical systems

Sizes: 3/0 AWG – 600kcmil

Application: Primary distribution circuits, substation interconnections, and high-stress coastal grid links

Why XHHW-2?

UL 44 certified, XLPE-insulated, 90°C wet/dry, and engineered for extreme moisture, humidity, and salt corrosion. Its cross-linked structure delivers better thermal stability and mechanical toughness than standard XHHW, making it ideal for hurricane-prone coastal zones.

Our Core Competitive Advantages

Full UL Certification Compliance: All cables carry valid UL 44/83/4703 listings, fully meeting NEC and Bahamian electrical codes—eliminating inspection failures.

Proven Island/Coastal Project Expertise: We’ve executed 10+ similar energy projects in Caribbean/Pacific islands, understanding salt, humidity, and hurricane challenges.

Superior Product Durability: Our XLPE-insulated cables (USE-2, XHHW-2 cable for electrical systems) resist saltwater and UV 3x longer than PVC-insulated alternatives.

Rapid, Reliable Delivery: Optimized production scheduling and maritime logistics ensured on-time, intact delivery to remote islands—no costly delays.

Customized Technical Support: On-site engineering teams assisted with installation, routing, and weatherproofing best practices.

3. Quality & Safety Assurance: Zero Compromises

Quality assurance was embedded in every stage to guarantee performance in the Bahamas’ harsh conditions:

Raw Material Inspection: Only UV-stabilized, corrosion-resistant XLPE and LSOH materials from certified suppliers.

Full Production Testing: Each reel undergoes voltage (2.5kV–4kV), insulation resistance, and temperature cycling tests.

Third-Party Verification: Independent labs certified compliance with UL 44, UL 83, and RoHS directives.

Salt Spray & Aging Trials: Cables passed 500+ hours of accelerated salt-spray testing—proof of long-term coastal durability.

Packaging for Tropical Shipping: Seaworthy, moisture-proof packaging to prevent damage during ocean transit.

This rigorous process ensured 100% of delivered cables met or exceeded project specifications.

4. Efficient Delivery & Flawless Execution

Despite logistical complexities of island distribution, we delivered on all commitments:

Fast Production: Expedited manufacturing without sacrificing quality.

Precise Logistics: Coordinated direct sea shipments to Nassau and Freeport, with streamlined customs clearance.

Phased Supply: Delivered cables in alignment with construction milestones, preventing on-site storage damage.

On-Site Support: Our technicians guided proper handling, termination, and weatherproofing—maximizing cable lifespan.

The entire cable supply was completed ahead of schedule, enabling the EPC to meet critical project milestones.

5. Measurable Project Outcomes & Client Success

Our cable solutions directly resolved the client’s pain points and drove project success:

Uninterrupted Performance: After 18+ months of operation, 0 cable failures in LNG plant and grid sections—even through hurricane season.

Grid Stability Boost: The upgraded system cut outage frequency by 45% and duration by 35%, aligning with national targets.

Cost Savings: Durable cables reduced maintenance/replacement costs by an estimated 40% vs. previous suppliers.
