For international solar portfolios, supply chain volatility is a constant pressure. But in regions like Japan, Australia, and parts of Europe, a physical threat is compounding financial risk: the wholesale theft of copper cabling. Copper’s high scrap value has turned solar farms into targets. As ground-mount installations expand into more remote areas, the risk increases.

In Japan alone, theft cases surged 20-fold between 2019 and 2024, with a single incident costing owners between $6.5M and $32M (USD) and causing downtime of two to three months for repairs. For IPPs and asset managers, this represents not just a loss of equipment, but a direct hit to revenue generation and PPA reliability. Traditional security measures are reactive; the industry needs a deterrent built into the infrastructure itself.

GBP addresses this challenge at the material level. By replacing traditional copper conductors with high-grade aluminum, we remove the criminal incentive entirely—aluminum has a fraction of the scrap value of copper. But switching materials in high-voltage applications is technically complex. Unlike standard low-voltage lines, 3300V circuits require rigorous insulation and durability standards.

Our solution is the GBP 3300V High-Voltage Aluminum Cable. It is the first and only cable of its kind to secure JET certification, the gold standard for electrical safety in Japan. This certification validates that the cable meets extreme benchmarks for structural integrity, voltage endurance, and water treeing resistance (EE type). It provides the same performance profile as copper but with a key commercial advantage: significant material cost savings.

For EPCs and procurement managers, technical validation is non-negotiable. Here is why the GBP cable de-risks your project:

・First-Mover Certification: As the industry’s first JET-certified 3300V aluminum cable, it provides a clear compliance pathway in markets that respect stringent third-party testing (IEC standards equivalent).
・Dual Savings (CAPEX & Insurance): Material costs for aluminum are inherently lower. We have documented cases where clients reduced initial CapEx by 3–10% on overall project costs. Furthermore, by mitigating theft risk, asset owners have successfully negotiated reduced insurance premiums.
・Legacy Compatibility: We provide engineered "hybrid terminals" to manage the bi-metallic connection between new aluminum cables and existing copper busbars, preventing galvanic corrosion and ensuring long-term reliability without requiring a full switchgear retrofit.
・Proven Scale: With over 200 kilometers deployed in under a year, the cable has moved from pilot phase to mass adoption, trusted by top-tier Japanese utilities and independent power producers.

GBP's approach extends beyond supplying cable. With 200,000 meters already in the field, we have developed the engineering insight and quality control systems to support long-term asset performance. Our differentiator is simple: we provide the technical validation—through JET certification and proven field results—that allows project teams to confidently specify aluminum from the outset. Whether you are designing a new solar farm or repowering an existing site plagued by theft, GBP offers the reliability of Japanese engineering and the track record to back it up.
