What TIEN LI OFFSHORE WIND TECHNOLOGY CO LTD does

Tien Li Offshore Wind Technology Co Ltd (天力離岸風電科技股份有限公司) is Taiwan's only MW-class offshore wind turbine blade manufacturer, founded in 2009 and headquartered in Taipei with its core manufacturing operation on a 21-hectare site inside the Taichung Port offshore wind industrial zone. The company produces 85-meter, 35-ton carbon-fiber blades for the Vestas V174-9.5MW platform, the world's largest commercial offshore wind blade, under a technology license transferred from MVOW (later fully absorbed into Vestas) following a 2018 MOU. Process capabilities span blade design, mold research and manufacture, composite layup, resin infusion, forming, painting, and proprietary mold flow analysis. The company also produces blades for downstream customers, with blade effectiveness improvement services included in its offering. Tien Li recorded its first revenue in March 2022 after completing the Taichung Port facility in 2021 and reached a 100-blade production milestone by August 2023, breaking Vestas' global V174 production record with a 17% efficiency improvement over standard man-hours.

Tien Li operates a B2B manufacturing model, selling blades and related services under contract to wind farm developers and wind turbine OEMs, with pricing not publicly disclosed. Primary customers include CIP (Copenhagen Infrastructure Partners) for the Changfang and Xidao wind farms, plus Zhongneng and the Hai Long project (1,044MW under Phase 3-2). The OEM backbone is a Vestas licensing relationship under which Tien Li is the only Vestas blade factory outside Europe, complemented by an MOU with Siemens Gamesa for localized blade O&M services. The company monetizes its core manufacturing line via blade delivery and acceptance, with revenue first recorded at NTD 25.96 million in March 2022. Expansion of the revenue base into professional services is underway through a March 2024 joint venture with Swire Renewable Energy covering Taiwan and Asia-Pacific O&M, a strategic partnership with Taiwan Wind Training to certify blade maintenance technicians (GWO standard, partnership signed July 2025), and participation in the Taiwan Team consortium targeting Formosa 4 (fixed foundation) and Formosa 5 (floating platform) wind farms of up to 3GW.

The company went public on Taiwan's emerging stock market (興櫃, ticker tpe:6793) in 2020 alongside a NTD 2 billion syndicated bank loan and a NTD 360 million cash capital increase. It is led by Chairman Wu Kun-Da (吳坤達) with General Manager Xiao Wei-Cheng bringing carbon-fiber expertise from the defense and sports industries. Headcount grew from approximately 400 (2022) to approximately 600 (2024), and the company holds ISO 9001/14001/45001 certifications covering both blade manufacturing and O&M services through July 2025. The company's stated strategic objective is to position Taiwan as the Asia-Pacific offshore wind turbine blade supply center, exporting locally developed supply chain capability and capturing both production and in-country maintenance revenue.

Direct peers

• Zhuzhou Times New Material Technology (TIMR): China-based manufacturer of wind turbine blades and composite materials, including large-format carbon fiber blades. Comparable to Tien Li in offshore-grade composite blade manufacturing and APAC localization strategy.
• TPI Composites: Independent global manufacturer of composite wind turbine blades, supplying multiple OEMs across onshore and offshore. Comparable to Tien Li as a blade-only manufacturer leveraging OEM licenses and producing large-scale MW-class blades from dedicated plants.
• LM Wind Power: Major independent wind blade manufacturer (a TPI Composites company), with global blade plants and long-standing OEM partnerships (GE, Vestas, SGRE). Most directly comparable to Tien Li in blade-only focus and offshore-grade composite technology.
• Mingyang Smart Energy: Chinese offshore wind OEM with vertical blade production. Comparable to Tien Li as a vertically integrated offshore turbine and blade manufacturer pursuing localization across Asian offshore wind markets.
• Sinoma Science & Technology: China-based composite blade and wind power materials manufacturer supplying domestic and APAC OEMs. Comparable through large-format composite wind blade manufacturing and localization-driven volume play in neighboring offshore wind markets.

Broad incumbents

• Siemens Gamesa (Siemens Energy): Tier-1 offshore wind OEM; Tien Li's partner for localized O&M on the Hai Long project. Comparable as the broader incumbent OEM offering full turbine systems that consume Tien Li's downstream blade and service work.
• Vestas Wind Systems: Global wind turbine OEM and Tien Li's licensor for the V174-9.5MW blade. Comparable as a broader incumbent in offshore wind systems while also being the parent IP and contract counterparty behind Tien Li's manufacturing.
• GE Vernova: US-based offshore wind OEM (Haliade-X platform) with broad renewables portfolio. Comparable as a global incumbent likely to source blades and O&M services in APAC markets where Tien Li could seek cross-OEM optionality.

Regional players

• Nordex: Europe-headquartered wind turbine OEM with strong onshore presence and growing offshore ambitions. Tangentially comparable as an alternative offshore OEM Tien Li could target for blade supply or O&M partnerships in Europe-adjacent markets.

Emerging players

• Bladena: Specialist blade service and structural engineering firm focused on blade O&M, repair, and life-extension. Comparable to Tien Li's growing O&M business and its Swire JV, but without manufacturing scope.
