Hengs Technology Completes Palau Solar-Storage Integration Project; US$2.7 Million to Be Fully Recognized in Q4

Taiwanese solar system integrator Hengs Technology (4582.TW) has reached a new milestone in its overseas expansion. The company undertook a Ministry of Foreign Affairs overseas contract — the Republic of Palau’s “One Stop Shop Building Solar Power Installation Project” — completing system integration and testing on August 30 with a ribbon-cutting ceremony. The project is valued at approximately US$2.7 million (about NT$85 million), with revenue expected to be fully recognized upon acceptance in Q4 2026.

Hengs Technology Chairman Chou Heng-hao said the Palau project goes beyond a simple solar PV installation. It represents a complete energy output solution integrating solar photovoltaics, battery energy storage systems, an Energy Management System (EMS), and electric bus charging infrastructure, covering the National Congress building, gymnasium, and Ministry of Education. Hengs Technology was involved end-to-end, from design planning, equipment procurement, and international logistics to construction management, system integration, testing, and grid interconnection coordination.

The ribbon-cutting ceremony was attended by Taiwan’s Minister of Foreign Affairs Lin Chia-lung, Palau’s Ambassador to Taiwan David Adams Orrukem, Hengs Technology Chairman Chou Heng-hao, alongside Palau President Surangel Whipps Jr., Minister of Public Infrastructure Charles Obichang, and Minister of State Gustav Aitaro — symbolizing concrete results in Taiwan-Palau green energy infrastructure cooperation.

Challenges and Technical Barriers of Overseas Projects

Chou Heng-hao noted that every link in an overseas project is tightly interconnected, making it far more difficult than domestic projects in Taiwan. “Cost and material control” ranks among the biggest challenges. In Taiwan, if a construction site runs short of materials, replenishment is readily available nearby; but in Palau, any shortage requires air freight, which not only delays schedules but also significantly inflates costs. Therefore, advance planning that integrates equipment procurement, international logistics scheduling, and construction progress is indispensable. Facing long-lead-time equipment such as transformers, energy storage containers, and steel structures, Hengs Technology leveraged its years of accumulated supply chain relationships to rapidly coordinate delivery schedules and mitigate lead-time risks.

On the technical side, to address the harsh wind speeds of the island environment, the structural design adopted an instantaneous design wind speed assessment of approximately 67.5 m/s and used SN490 structural steel, balancing wind resistance with steel weight reduction to avoid adding load to existing buildings. Additionally, Palau’s grid voltage is 480V, differing from the 380V or 220V commonly used in Taiwan. Hengs Technology re-integrated inverters, energy storage PCS, power distribution equipment, and charging stations according to local grid conditions, and used the EMS to regulate generation, storage, and charging loads, enabling successful project completion.

From EPC Contractor to Energy Integration Service Provider

Hengs Technology has been deeply engaged in renewable energy for nearly 30 years, accumulating hundreds of domestic and international project records, including 12 in Japan, 3 in Cambodia, and 7 in other overseas markets. The company has also independently developed the “H-ELink” energy management platform. The Palau project marks an upgrade from previous solar PV installations to a complete system export encompassing photovoltaics, energy storage, EMS, charging equipment, and grid interconnection.

The company stated that its core advantages lie in “turnkey project integration capability” and “precise cost and resource control,” enabling it to effectively connect procurement, logistics, engineering, and testing under constrained timelines and overseas supply chain conditions, keeping cost risks within a reasonable range while ensuring construction quality. This is a capability that many international EPC contractors find difficult to match simultaneously, and it is the key to Hengs Technology’s recent transformation from a solar EPC contractor to an energy integration service provider.

Overseas Replication Model and Future Outlook

For Hengs Technology, the significance of the Palau project extends beyond a single project’s revenue. It establishes an energy integration model that can be replicated overseas, combining Taiwan’s complete green energy supply chain with local engineering resources abroad, extending from equipment supply to design, construction, commissioning, and O&M services.

Analysts note that Hengs Technology is expected to use the Palau project as a showcase, continuing to evaluate Pacific island nations and Southeast Asian markets, with Vietnam — where it has already established a subsidiary — as its primary base. Meanwhile, the revenue mix is expected to extend from traditional EPC engineering income toward diversified revenue streams including energy storage, O&M services, and overseas system integration. Driven by global ESG policy initiatives, both domestic and international growth momentum appears promising.
